AB  - Природно-математички факултет као институција не постоји више од три деценије, мада је импозантна зграда из средине 20. века на Студентском тргу и даље у мислима Београђана позната као зграда ПМФ-а. 

Природно-математички факултет Универзитета у Београду издвојио се из  Филозофског факулета 1947. године. У тренутку оснивања, ПМФ је био смештен у данашњој згради Ректората, велелепном Капетан Мишином здању. Те школске године овај факултет уписало је 565 студената, а завршило само 26 студената. У наредним годинама број студената се повећавао, а расположиви простор постао је недовољан за потребе студирања све већег броја студената. Међутим, зграда Капетан Мишиног здања, као културно-историјски споменик, била је под заштититом државе, па стога никакве реконструкције и проширења нису били могући. 

Професор Вукић Мићовић, користећи позицију ректора Универзитета у Београду (1952-1954), као и подршку колега, успео је да обезбеди простор за подизање заједничке зграде за Хемијски институт, Физичко-хемијски институт и Минералошки завод. Осмишљавању изгледа зграде значајно и посвећено су допринели професори поменутих институција, хемичари, Вукић Мићовић и Ђорђе Стефановић, физикохемичар, Павле Савић и геолог, Стојан Павловић.

У селидби лабораторијског посуђа и прибора из Капетан Мишиног здања добровољно су учествовали и студенти. Зграда је усељавана постепено, а касније је као орган управљања непокретностима уписан Природно-математички факултет. Факултет је у овом облику постојао до 1990. године, када се сви одсеци, које су биле у његовом саставу, раздвајају на засебне факултете и то: Хемијски, Математички, Географски, Биолошки, Физички и Факултет за физичку хемију. 

Сви набројани факултети и данас користе зграду на Студенстком тргу, а Хемијски факултет површински и у бројности особља има највећи удео у њој. Додатне просторије на другим локацијама на располагању су неким од наведених факултета, али се уопштено може рећи да проблем простора за већину факултета потеклих из ПМФ-а није ни данас решен, а посебно се у томе истичу Географски и Биолошки факултет. 

Шездесет година од завршетка храма природних наука у Београду овај подухват и даље делује недостижно за Управе многих факултета у Србији, иако потребе за модернијим простором без престанка расту.

AB  - The aim of this paper is to investigate the effects of the programme for professional development of chemistry teachers on their competencies for conducting formative and summative assessment in chemistry teaching. The programme participants were 30 chemistry teachers from primary and secondary schools. Data were collected using a questionnaire at the beginning and at the end of the programme implementation. The programme included four workshops with the same structure: the introduction, group work and the discussion of the results obtained through group work. The workshops focused on: i) the assessment as a support for chemistry learning; ii) the harmonization of teaching and learning activities, formative and summative assessment, feedback from formative assessment and the criteria used to evaluate students in summative assessment; iii) the evaluation of the validity of tasks used for formative and summative assessment according to the curricula aims and the educational standards; iv) designing tasks for monitoring students’ progress towards certain educational standards. Teachers’ responses show the impact of the programme for the development of their competencies for assessment, particularly regarding formative and summative assessment and designing various kinds of assessment in accordance with the achievement standards.

AB  - The COVID-19 pandemic and the suspension of face-to-face learning at the University of Belgrade -
Faculty of Chemistry (UBFC) influenced the education of all chemistry students. The realization of the
experimental part of the studies presented a major challenge within all study programmes (Huang, 2020;
Youssef et al., 2020), while the realization of school practice was an additional challenge within the
education of pre-service chemistry teachers. In order to examine the pre-service chemistry teachers’ views
on the quality of the educational processes during the pandemic, we developed a voluntary anonymous
online survey using Google Forms. Six pre-service chemistry teachers, students of the fifth year of the
integrated undergraduate and graduate academic studies at the UBFC, participated in the research. The
survey consisted of four parts with 42 questions altogether. In the first part, the students’ demographic
data were collected. In the second part, the respondents were given several sets of questions regarding
ICT. In the third part, using a five-point Likert scale, the respondents expressed and then explained their
views regarding the general impact of the pandemic on their learning, the effectiveness of online lectures
and theory exercises within different chemistry and chemistry didactics courses, and the effectiveness of
assessments. In addition to this, they estimated the effectiveness of the laboratory exercises, which were
conducted face-to-face during one part of the semester, and the school practice in the pandemic
circumstances. In the last part, the respondents assessed the advantages and disadvantages of online
teaching and its impact on the development of teacher competencies. They put forward some suggestions
on how to improve online teaching and their views on the combination of online and face-to-face teaching
in the future. Respondents had no experience with online teaching/learning before the pandemic, but now
they spend two to eight hours a day engaged in these activities. All students usually use the PDF and PPT
presentations which accompany lectures, five of them use the Faculty's e-platform, while YouTube
videos, e-books, educational applications and web sites and the recordings of online lectures are used less
frequently. The effectiveness of online instruction within chemistry courses was rated 4 (Agree) by most
students (five out of six). Similarly, students rated the effectiveness of the online instruction within
chemistry didactics courses as 4 (three out of six) and 5 (two out of six). The effectiveness of online
theory exercises was rated the same for both chemistry courses and chemistry didactics courses: grade 5
was given by three out of six students, grade 4 was given by two students and grade 3 by one student.
Three out of six students rated the effectiveness of school practice as 3, two students as 4, while one
student rated it 5. The students singled out the lack of contact with pupils at schools as a major obstacle.
However, the preparation for online teaching helped them gain some useful experience for their future
practice. None of the students fully enjoyed online teaching and most of them were more comfortable
during face-to-face instruction due to better social interaction.

AB  - The aim of this research was to establish the effects of argumentation and the quality of arguments related to history of the development of organic chemistry: (i) on the level of the pupils’ knowledge about the composition, structure and general properties of organic compounds; and (ii) on their perception of the key aspect of NOS that scientific knowledge is tentative. A quasi-experiment involved two parallel groups of 14-year-old pupils, a total of 105 of them. The pupils in group А, as opposed to those in group B, were exposed to argumentation in the context of history of the development of organic chemistry. The instruments in this research were a diagnostic test, used to establish how well matched the groups were in terms of previous knowledge, and a post-test, the purpose of which was to establish the effects of argumentation on the pupils’ achievements. After both tests, the pupils expressed their views of the fact that the scientific knowledge is tentative using a five-point Likert scale. All the arguments produced in group A were classified in four categories based on their structure. Although a moderately positive correlation between the quality of arguments and the post-test achievements in group A was established, no significant difference between the arithmetic means in the post-test in groups A and B was found. After the intervention, a significantly higher number of pupils in group A were of the opinion that scientific knowledge is tentative, compared with the number of pupils from group B.

AB  - The aim of this research was to diagnose the students’ problems in the process of connecting the
macroscopic, submicroscopic and symbolic level of representation of physical and chemical changes of
substances and to investigate the potential of demonstration experiments for the purpose of eliminating
those problems. A total of 63 students (31 boys and 32 girls) attending the seventh grade of three primary
schools in Belgrade participated in this research. The data were collected using a test and an interview
which was conducted according to the protocol. The students completed a worksheet with requirements
related to the demonstration experiments. The worksheet had been designed in such a way so that it
guided the students in the process of considering the changes of substances and the analysis of their
answers provided an insight into how that process had gone. The work with each class included: pretesting,
completing the worksheet, post-testing and postponed testing. In order to compare the students’
achievements before and after observing demonstration experiments, the same test was used for the
purpose of the pre- and post-testing. After the lesson, four students from each class (12 students
altogether) were interviewed. Three months later, at the beginning of the following school year, the
students were tested again using the same test (postponed testing).
In the post-test, which was administered immediately after observing the demonstration
experiments, a larger number of students gave correct answers to eight out of nine tasks compared to the
pre-test (for one task the number of correct answers was the same in both tests). For one of the eight tasks
which had been done better, the difference in the percentage of correct answers was statistically
significant. The analysis of worksheets showed that the percentage of students who had provided a correct
answer decreased as the complexity of the mental processes required from the students increased, while
the percentage of the ones who did not provide an answer increased. The analysis of the answers in the
interviews pointed out the problems in connecting the symbolic, submicroscopic and macroscopic level of
representing substances and their changes. In the postponed testing, the students had better achievements
in seven tasks compared to the pre-test, and in two tasks compared to the post-test. The statistically
significant difference in the percentage of correct answers, which was found by comparing the results of
the post-test and the pre-test, was also found for the same task when the results of the postponed test and
the pre-test were compared. That task could be related with the observed demonstration experiments.

abstract = "The aim of this research was to diagnose the students’ problems in the process of connecting the
macroscopic, submicroscopic and symbolic level of representation of physical and chemical changes of
substances and to investigate the potential of demonstration experiments for the purpose of eliminating
those problems. A total of 63 students (31 boys and 32 girls) attending the seventh grade of three primary
schools in Belgrade participated in this research. The data were collected using a test and an interview
which was conducted according to the protocol. The students completed a worksheet with requirements
related to the demonstration experiments. The worksheet had been designed in such a way so that it
guided the students in the process of considering the changes of substances and the analysis of their
answers provided an insight into how that process had gone. The work with each class included: pretesting,
completing the worksheet, post-testing and postponed testing. In order to compare the students’
achievements before and after observing demonstration experiments, the same test was used for the
purpose of the pre- and post-testing. After the lesson, four students from each class (12 students
altogether) were interviewed. Three months later, at the beginning of the following school year, the

AB  - The aim of this research was to investigate the attitudes of fourteen-year-old students towards
science, scientific-research work and the importance of scientific work. The following research questions
were raised:
(i) What are students’ views on science and scientific-research work?
(ii) What are students’ attitudes towards the contribution of scientific work to the development of an
individual and the society?
(iii) What are students’ preferences towards science?
A total of 275 students (146 boys and 129 girls) from six primary schools in Belgrade participated
in this research. The research instrument was a questionnaire through which the following data were
collected: (i) students’ views on science, experiments and the main activities of scientists in natural and
social sciences; (ii) students’ attitudes towards the importance of scientific work for an individual and the
society; (iii) if there were some scientists and scientific discoveries that had made an impression on
students and if they themselves wanted to pursue a career in science in the future.
Based on the answers to the question What is science? it can be concluded that a larger
percentage of students perceives science as dynamic (the answers which point out study, research,
experimenting, making discoveries) than as static (the answers in which science is defined as a set of
knowledge or as a discipline). In students’ opinion, experiment is a part of scientific-research work, it
involves working under artificial, strictly controlled conditions (in a laboratory) and it most often involves
working with substances. Conducting experiments is one of the major activities of scientists, while other
activities mentioned also include the ones which are characteristic of scientific-research work, such as:
observation, analyzing, constructing and testing hypotheses, proving and deduction. Students have
identified certain similarities and differences in the activities done by scientists in natural and social
sciences. In their opinion, regardless of whether a scientist conducts research in the field of natural or
social sciences, he is hard-working, persistent and dedicated to his work, he has a thirst for knowledge,
conducts research and makes new discoveries.
The participants consider science important, both for them personally and for the society in
general. According to their answers, science is important because it enables the acquisition of new
knowledge and the development of an individual and the society and because it provides answers to many
questions.
The largest number of participants admire the discovery of electricity, and accordingly Nikola
Tesla is the scientist whom the largest number of students admire. The periodic table of elements is the
discovery in the field of chemistry which has impressed the students, while Mendeleev is the second most
favourite scientist. It can be observed that students do not have any role models among today’s scientists.
Both the discoveries which relate to modern technologies and the discoveries which represented a
revolution in the development of the society have been mentioned in the students’ answers. Students’
attitudes towards their future career in science are divided. A lack of interest in science or their own poor
achievements in science subjects are the most common reasons for not seeing themselves as scientists in
the future. A statistically significant correlation between a student’s chemistry grade and his/her desire to
pursue a career in science and a correlation between the participant’s gender and the affinity for the
profession of a scientist (in girls’ favour) have been confirmed. In both cases the correlation is weak.

AB  - Како у учионици уз учење научних садржаја, подстаћи учење о природи научног знања и научноистраживачког рада? Бројни су радови у којима се препоручују садржаји из историје хемије као погодан контекст за учење научних појмова и учење о природи науке, тј. за развој обе компоненте научне писмености. Садржаји из историје науке пружају увид ученицима у развој научних идеја, у процес који је доводио до одређених сазнања, у начин резоновања научника, и могу подстаћи ученике да преиспитају сопствени резон и знање. Уграђивање садржаја из историје науке у наставни процес може помоћи ученицима да увиде да је наука резултат људске активности, да научно знање зависи од расположивих доказа, да се стално проверава и развија, тј. да је његова природа променљива.
Аргументовање је активност која је уграђена у научноистраживачки рад, али и у образовни процес. Аргументовано дискутовање је једна од вештина које чине научну писменост. Пружање разноврсних ослонаца ученицима за резоновање, за развој критичког мишљења и способности да формулишу аргументе у научном контексту, може допринети постизању циљева образовања у области природних наука, укључујући и хемију.
Имајући у виду претходно речено, изведено је истраживање са ученицима узраста 14 година приликом учења прве теме у области органске хемије - Увод у органску хемију, с циљем да се испитају: (а) ефекти наставних ситуација у којима ученици продукују аргументе за и против у вези са садржајима из историје развоја органске хемије, на ниво знања о саставу, структури и општим својствима органских једињења; (б) ефекти примењеног начина рада на опажање променљиве природе науке; (в) сложеност и тачност ученичких аргумената. Процењено је да се садржаји из историје развоја органске хемије могу прилагодити предзнању ученика узраста 14 година и, уз претходно знање, да могу послужити као основа за формулисање аргумената.
Иако ефекти наставе која укључује садржаје из историје науке нису занемарљиви, њено планирање и подстицање учења у историјском контексту представља посебан изазов, јер је потребно ученицима модерног доба указати на релевантност открића из претходних векова.

AB  - The content knowledge of pre-service chemistry teachers which includes, among others domains of chemistry, the knowledge about the history of chemistry, represents the basis for the formation of pedagogical content knowledge of teachers. Pedagogical content knowledge is a part of chemistry teachers’ competences that can be defined as a combination of pedagogy and the content of chemistry, including the history of chemistry as well. According to that we created the workshops within the framework of course of the history of chemistry for the pre-service chemistry teachers with the aim to enable them to gain insight into development of chemistry through different historical periods and, in the same time, to offer them the models for their future work with school students on elaboration of chemistry concepts from historical point of view. The workshops comprised different pre-service chemistry teachers’ activities, for example: work with different sources of historical facts, creating a timeline, performing different roles in quizzes (competitors, items creators, moderator, and supervisors of the accuracy of the answers). The work within the workshops has potential to improve the pre-service chemistry teachers understanding on development of chemistry knowledge. The workshops could be also adapted for students of different ages and level of education.

should educate teachers according to these goals. With this view we prepared and performed the
workshop for the pre-service chemistry teachers. Also, we conducted the same workshop with the
in-service chemistry teachers in two countries, Serbia and North Macedonia.
In the framework of the workshop we explored knowledge of the pre-service and in-service chemistry teachers about the definition and goals of sustainable development and engaged the participants with activities throughout they had opportunity to consider issues from the perspective of sustainable development. The workshop contains several parts and its realisation encompasses two classroom periods (90 minutes). Socrative teacher app was used for gathering data during the workshop. In the beginning the participants filled the questionnaire. Some questions from the questionnaire were chosen for a further discussion and different texts or video materials were provided to participants in order to support their reconsideration of previously stated answers. This step was performed several times during the workshop. In the end of the workshop the participants filled the questionnaire again. According to the obtained results, this workshop could be used for improvement of the pre-service and in-service chemistry teachers further work associated with the goals of sustainable development.

AB  - During the past fifteen years, students of the University of Belgrade - Faculty of Teacher Education
learned chemistry within the course Introduction to Natural Sciences. In the realization of this course, teachers from three faculties of the University of Belgrade (the Faculty of Biology, the Faculty of Physics and the Faculty of Chemistry) were engaged. Elementary teachers educate children ages 6 (or 7) to 10. At the beginning of work we usually faced with the situation that the elementary preservice teachers did not like chemistry and they did not feel confident in their knowledge of chemistry. Because of that during the previous period we continually developed syllabus for chemistry teaching and learning within science education of elementary teachers and changed the activities in the classroom in order to improve their knowledge, skills and attitudes toward chemistry and to prepare them to teach chemistry contents within science effectively.
In this presentation the structure of syllabus for elementary pre-service teachers’ education in
chemistry, the directions of its development, the activities in the classroom, as well as the formative
and summative assessment will be shown. We will also consider the problems and obstacles in the
education of elementary teachers in the field of chemistry and sciences that are, despite our efforts, remain unresolved.

AB  - Game-based learning [1,2] can be introduced in schools to support the learning experience, thus
helping students to connect the previous knowledge and the one learned from the game. Games
are fun, engaging and motivating, and if they incorporate chemistry content, they could be a powerful pedagogical tool with a great educational value. Well-designed educational games develop creative thinking, inquiring and problem-solving skills, higher-level thinking skills, collaborative or cooperative learning, self-confidence and decision making [3]. They encourage discussion among students, but also with the teacher, which is a crucial part in developing thinking, clarification and correction of potential misunderstandings and misconceptions.
The escape room method [4,5] has become a very popular innovative method to the chemistry
teaching. Motivated by the International Year of Periodic Table [6], we created and performed
several escape rooms related to the Periodic Table concepts in North Macedonia and Serbia [7,8].
Namely, we introduced educational games and puzzles among chemistry teachers within the
programme for their continuing professional development in two countries. The escape room
included five puzzles: Coded Message, Hidden Words, Improvised Chemistry Competition, Cool
Chemistry Coffee Receipt and The Queen and the King puzzle.
This is rather novice and innovative teaching practice in North Macedonia and Serbia and we are
optimistic to disseminate this idea further together with the teachers in our countries. These
educational games and escape rooms have a potential to increase the students’ interest and
motivation to learn chemistry.

AB  - Проверавање ученичких постигнућа саставни је део наставног процеса и у великој мери обликује начин на који учиници уче. Ученичка постигнућа зависе од примењеног начина проверавања. Тако на пример, ученици који остварују висока постигнућа приликом једног начина проверавања не показују једнаку успешност уколико се начин проверавања промени. Због тога би требало размотрити различите стратегије проверавања и приближити их већем броју ученика.
Садржаји из историје хемије могу служити као контекст за учење хемијских концепата и разумевање природе науке. Такође, контекст историје хемије може се применити и приликом проверавања ученичких постигнућа. Циљ овог истраживања био је да се испитају идеје ученика о хемијским реакцијама и тешкоћама у разумевању закона одржања масе у тим реакцијама кроз приступ који подразумева садржаје из историје хемије. Помоћу текстова, који су били саставни део употребљеног инструмента, ученицима је презентован рад три научника, Лавоазјеа, Ландолта и Ломоносова, у вези са законом одржања масе. Текстови су кроз историјски контекст пружали информације потребне за решавање задатака који су се налазили у наставку инструмента, а који су захтевали предвиђање резултата, формулисање објашњења, извођење закључака, повезивање хемијског знања са ситуацијама из свакодневног живота.
У истраживању су учествовали ученици различитог узраста (укупно 301 ученик) и то: 90 ученика седмог разреда, 107 ученика осмог разреда основне школе и 104 ученика другог разреда гимназије природно-математичког смера.
Постигнућа ученика нису била висока ни у једној групи ученика, а генерално гледано, најуспешнији су били ученици другог разреда гимназије. Информације из историје хемије, о раду три научника у вези са законом одржања масе, неким ученицима биле су корисне приликом формулисања одговора, док другим ученицима, са развијеним мисконцепцијама, нису биле значајне. Тешкоће ученика у разумевању закона одржања масе најчешће су биле повезане са предвиђањем и објашњењем промене масе у отвореном реакционом систему и то углавном у оном где је гас реактант. На основу ученичких одговора, запажено је да су ученици често пружали објашњења у виду дословне формулације закона одржања масе, без критичког разматрања информација доступних у текстовима или задацима.

AB  - The aim of this study is to explore the possible use of the indicators of creative thinking, taken from the Trefoil concept, in the field of chemistry when assessing students' performance, determining the potential for creative development and providing directions for further work. In this way, chemistry instruction might contribute to encouraging the creative abilities of students necessary in the modern, fast-paced world. There is the question of whether the indicators of creative thinking can be useful in evaluating students' achievements in the situation of solving open-ended tasks in the field of chemistry and the kinds of results achieved by students. The research sample included 97 eight-grade students from two primary schools in Belgrade. The research was conducted at the end of the eighth grade in the school year 2016/17, after the entire chemistry curriculum for primary school had been covered. An appropriate achievement test was constructed and then implemented. The obtained results indicate that a large number (30%) of students are capable of formulating several acceptable answers to the given open-ended task, which is a characteristic of divergent thinking in sciences. This finding is even more relevant if we bear in mind that the students from this sample did not have any similar type of demands or experiences in previous classes. This points to the fact that there is a significant potential for developing creative thinking, which might be realised if students solved open-ended tasks more frequently.

AB  - The aim of this research was to investigate whether pupils aged 13, at the end of their first year of studying chemistry, are capable of perceiving the macroscopic and the submicroscopic level of the previously learned contents on chemical reactions, and whether they relate them to the chemical equations (the symbolic representation). Another aim was to establish how much demonstration experiments contribute to a better linking of the mentioned levels. The research featured 69 pupils of the seventh grade from three primary schools. The pre-test was conducted, following which experiments were demonstrated, and the post-testing was carried out in the end. After the intervention, a total of 12 pupils were interviewed about which aspects of chemical reactions they thought of based on the chemical equations. A statistically significant difference in two out of five requirements of the post-test, compared to the pre-test, indicate that the demonstration experiments may contribute to a better linking of three levels of representing chemical reactions. However, when one compares the pupils' answers in the test and in the interview, it can be observed that the correct answers in the test are not always based on understanding the concepts in connection with the chemical reaction.

abstract = "The aim of this research was to investigate whether pupils aged 13, at the end of their first year of studying chemistry, are capable of perceiving the macroscopic and the submicroscopic level of the previously learned contents on chemical reactions, and whether they relate them to the chemical equations (the symbolic representation). Another aim was to establish how much demonstration experiments contribute to a better linking of the mentioned levels.

AB  - The development of students’ abilities to formulate arguments, reason and think critically in scientific context is one of the goals of science education [1]. Episodes from the history of chemistry can serve as that scientific context. The research was conducted with the aim of examining students’ ability to apply the newly acquired knowledge about composition, structure and general properties of organic compounds to formulating arguments for and against the views of the scientists who had contributed to the development of organic chemistry in the 19th century. A total of 43 students aged 14 participated in this research in the school year 2017/18. Firstly, the students individually read the text about the composition, structure and general properties of organic compounds and how these compounds are different from inorganic compounds. After that, they listened to audio-voice recordings in which the views of scientists who are given the credit for the development of organic chemistry were interpreted (Jоns Jacob Berzelius, Friedrich Wоhler, Antoine - Laurent de Lavoisier, Friedrich August Kekulе von Stradonitz and Archibald Scott Couper). After each recording, students were expected to individually estimate whether the presented views of the scientists would be acceptable today or not and to write arguments for and against. The students were given the opportunity to use the text they had previously read as the source of information for formulating arguments. In this approach the students were in a position to apply the acquired knowledge in order to estimate the views of the scientists, and to improve their high-order cognitive skills.
A conclusion supported by at least one justification was labelled as an argument in the analysis of students’ answers in this research. The structure and contents of arguments were evaluated jointly on a 0-to-5 scale according to the modified version of the methodology described in the literature [2]. One third of the total number of produced arguments contains a conclusion, justification and additional explanation of the justification. At the same time, this kind of argument is the most frequent. Based on the obtained results it can be concluded that the episodes from the history of chemistry in combination with some other sources of information can serve as a fruitful context for formulating arguments and stimulating high-order cognitive skills.

AB  - A lot of chemistry teachers express their concern regarding the thinking levels their students use. They wonder how to improve the higher level thinking skills of their students. Teachers are usually satisfied with the students’ convergent thinking during the problem solving, i.e. when they apply the main chemistry ideas logically and produce one correct answer. The key problem of this research is the divergent thinking of primary and secondary school students when they solve open-ended designed chemistry problems, with the contribution of logical, critical and evaluative thinking. Divergent thinking is defined using indicators such as: (i) fluency – the ability to think of many ideas or many possible solutions to a problem, and (ii) flexibility – the ability to use ideas in a new, different, and unusual way 1.
The first examination was conducted with primary school students aged 14 in the school year 2016/2017. The obtained results have shown that 30% of students were able to formulate more acceptable responses to the given open-ended chemistry problems, i.e. the fluency and flexibility of students’ answers were indicated. This finding is important because the students from this sample had not had this kind of experience and demands in their previous education. In addition, the primary school students showed that they could combine the previously acquired knowledge of chemistry, connect it with everyday life, and thus find original answers.
The second examination was conducted with secondary school students aged 16 in the school year 2017/2018. It was shown that about 30% of the secondary school students were able to produce different responses in the items which did not require chemical calculations. As far as stoichiometric calculations are concerned, the percentage of students who were able to formulate more acceptable responses to the given open-ended chemistry problems was less than 10%.
The results of these studies can be used to further develop the approaches which support the divergent thinking of primary and secondary school students in teaching chemistry, as well as to monitor and evaluate the effects of such work by evaluating students' achievements in open-ended problems.

Садржаји из историје науке треба да буду презентовани тако да ученици кроз њих могу да сагледају етапе кроз које су научници пролазили како би дошли до открића што доприноси развоју научног мишљења код ученика.
Иако ученици могу да сагледају бројне карактеристике природе науке и граде разумевање основних научних концепата кроз историјску перспективу, успех оваквог учења зависи од мотивације ученика за учење садржаја науке у историјском контексту и способности увиђања релевантности историјских садржаја за живот у савременом друштву.

AB  - Образовање треба да омогући сваком појединцу знања и вештине као поуздану основу за резоновање и закључивање, доношење одлука и предузимање активности ради остваривања потреба у личном животу, ради испуњавања професионалних задатака и пружања доприноса развоју друштва.
Које су основне идеје које желимо да пренесемо ученицима? Које идеје желимо да пренесемо ученицима у основној школи, а које у средњој школи? Какву слику би требало да им пружимо о науци?
Знања из природних наука се могу представити у облику генерализованих идеја које помажу у разумевању великог броја информација које доноси наука, а први корак јесте њихово идентификовање. Централне идеје науке су неопходне за развијање компетенција које су потребне за решавање проблема у различитим областима. Оне могу помоћи наставницима у планирању активности које воде разумевању појмова и основа су за праћење напретка ученика у учењу.
У оквиру радионице идентификоваћемо идеје које се могу означити као контекстуалне и концептуалне идеје. Контекстуалне идеје могу бити специфичне и опште, а указују на оно разумевање хемије које је релевантно за појединца и друштво. Концептуалне идеје обухватају фундаментално разумевање појмова који се односе на супстанцу, њену структуру, својства и промене, као и разумевање природе науке и научноистраживачког рада. Контекстуалне и концептуалне идеје су међусобно повезане. Контекстуална идеја може обухватати више различитих концептуалних идеја, док специфична концептуална идеја може подржавати разумевање неколико контекстуалних идеја.

AB  - Reagent stereocontrol in the proline-catalyzed aldol reaction of 2,2-dimethyl-1,3-dioxane-5-one 1 with chiral aldehydes has been investigated. Synthetically useful levels of diastereoselectivity could be achieved in reactions with acyclic chiral alpha-oxy and alpha-amino aldehydes in both matched and mismatched cases. By using this reaction as a key step, two medicinally relevant azasugars, 1-deoxy-galactonojirimycin (9) and 2,5-dideoxy-2,5-imino-d-altritol (10), were efficiently synthesized.

AB  - The aim of this research was to explore the effects of two approaches, designated as the historical and the contemporary one, on the level of students' understanding of the properties and the practical use of gases. Our research hypothesis was that the historical context of the discovery of gases and the study of their properties would deepen students' understanding of the properties and the practical use of gases more than the contemporary context. A total of 129 students attending the eighth grade of primary school, aged 14, took part in the research project. After taking a pre-test, the students were divided into two groups (A and B respectively), equal in terms of their test scores. Group A (63 students) was exposed to the historical approach, whereas group B (66 students) was exposed to the contemporary approach. The students from group A individually dealt with a text that presented various episodes from the scientific-research work of Joseph Priestley, whereas the students from group B dealt with a text pertaining to the properties and the use of gases in contemporary society. Having been exposed to different approaches, all the students did a post-test. No statistically significant difference was established between the overall results of the students who had been exposed to the historical approach and those exposed to the contemporary approach, and the research hypothesis was rejected. However, one statistically significant better score in one of the post-test items in group A may be connected with the influence of the corresponding episode from the history of science.

AB  - The aim of this research was to explore students' ideas about chemical reactions and difficulties in understanding the law of conservation of mass in such reactions by using an approach that started from presentations of scientists' work associated with the law. The developed test items relied on: 1) the historical contents that illustrate the experimental work of three scientists (Lavoisier, Landolt and Lomonosov); 2) the description of school experiments and 3) real life situation. In this way, students would have an opportunity to show understanding of the law of conservation of mass in two contexts, one based on the stories from the history of chemistry and the other contemporary, based on school laboratory experiments and real life situation. Students of different ages were selected for the research: the seventh and the eighth grade of primary school (age 13-14), and the second year of grammar school (age 16). The research involved a total of 301 students. The results indicated that students' difficulties were mostly associated with the predictions and explanations of mass changes in open reaction systems in which a gas was a reactant than with the reactions in which a gas was a product.

AB  - History of chemistry could be an important part of the curriculum for pre-service
chemistry teachers’ education. This allows them the deeper understanding of nature
of science and scientific work, as well as to build a base for future planning the
contextual approaches through which their school students could learn about nature
of science. History of Chemistry is taught in the fourth year within the integrated
academic studies curriculum (300 ECTS) for chemistry teachers’ education at the
Faculty of Chemistry University of Belgrade.
During the last three school years at the very beginning of the course of History of
Chemistry the estimation of the knowledge of some historical facts, such as the
scientific contribution of Robert Boyle, Henry Cavendish, Joseph Priestley, Antoine
Lavoisier, John Dalton, Jöns Jacob Berzelius, Alessandro Volta, Michael Faraday was
conducted. These scientists were chosen according to the previous analysis of the
syllabuses of different secondary school and university chemistry and physics
subjects. In this way, we were able to examine whether students pay attention to the
work of scientists when they study various subjects from chemistry and physics
domain. In addition, we asked the students whether they read texts from the history
of science, what was the most important scientific discovery from their point of view,
who was the most significant scientist in their opinion, whether they had a role model
among scientists. Also, we asked students to describe an experiment that they knew
from the history of science.
The obtained results showed that students, future chemistry teachers, have
developed certain attitudes about chemistry as a science, but they possess little
knowledge about the scientific work of scientists. These findings are later useful for
the lessons and workshops planning within the course of history of chemistry.
