“…It means that students can develop better scientific understanding by engaging the construction of representation (Tang et al, 2014). Thus, it can be concluded that studying chemistry includes aspects of macroscopic, sub-microscopic and symbolic level (Barak and Farraj, 2013;Adadan et al, 2010;Treagust et al, 2003;Wu et al, 2001;Johnstone, 1991).…”

“…Hence, to help introducing this level, a media that helps students to see and understand sub-microscopic level explanations of chemical phenomena is needed. Learning chemistry through drawing media such as animations enhances students' interest to study representation in chemistry (Barak and Farraj, 2013). In this case, the media must be able to reduce the abstraction level of sub-microscopic level by giving students both its visualization and relevant verbal explanation.…”

Among three levels of chemical representation, the sub-microscopic level is the most difficult to learn by students. To solve the problem, it is assumed that the concept of the discontinuous nature of matter or particle concept should be mastered initially by students before they learn sub-microscopic representations of further chemical phenomena. 131 junior high school students from two schools participated in this study. The study was carried out by implementing structureoriented chemistry teaching on the particle concept that was assisted by the courseware and was continued by teaching the changing state of matter. The research instruments were written tests, questionnaire, observation sheet and interview guideline. Research data were collected before and after the use of the courseware, as well as before and after the teaching of the changing states of matter. The results show that the use of the courseware increases students' understanding of the particle concept for both male and female groups. Meanwhile, particle concept only affects the students' understanding of sub-microscopic representations of the changing states of matter in general and based on gender.

“…When teaching chemistry courses in most education colleges, lecturers still use textbooks and two-dimensional pictures to depict molecules. However, many researchers claim that still pictures are not adequate for building a mental model of new concepts and phenomena and that utilizing dynamic pictures is essential to promoting conceptual understanding [7]. Researchers have found that integrating visual representations such as computerized molecular models, simulations, and animations into the teaching of science may promote students' understanding of unobservable phenomena [8], and afford them the opportunity to make abstract concepts visible.…”

In developing this study, we hypothesized that the integration of computerized techniques and modeling tools into traditional face-to-face instruction can produce a better hybrid model of teaching, capable of motivating students and improving their attitude toward science in general, and toward chemistry in particular. We tested how molecular visualizations and three-dimensional simulations affect students' conceptual understanding of chemistry and their attitudes toward learning chemistry. During the academic year 2016-2017, we incorporated Avogadro software into teaching and tested how it affected students' performance on chemistry exams in their courses. The difference in average scores between the two groups (8.2 points for the experimental group and 6.4 points for the control group) was significant. Student feedback following the initiative was positive and encouraging. Most students indicated that learning chemistry with Avogadro was extremely helpful, bringing the microscopic world of molecules closer to them, and they felt that they would like to see such software integrated into their chemistry studies from day one. Other parameters will be tested in continuation of this study, such as students' attitudes toward learning chemistry and their inquiry skills.

Proteins are the most ubiquitous macromolecules found in the living cells and have severals physiological functions. Therefore, it is fundamental to build a solid knowledge about the proteins three-dimensional structure to better understand the living state. The hierarchical structure of proteins is usually studied in the undergraduate discipline of Biochemistry. Here we described pedagogical interventions designed to increase the pre-service teacher chemistry students' knowledge about protein structure. The activities were made using alternative and cheap materials to encourage the application of these simple methodologies by the future teachers in the secondary school. From the primary structure of insulin chains, students had to construct a three-dimensional structure of insulin. After the activities, the students highlighted an improvement of their previous knowledge about proteins structure. The construction of a three-dimensional model together with other activities seems to be an efficient way to promote the learning about the structure of proteins to undergraduate students. The methodology used was inexpensive and simple and it can be used both in the university and in the high-school.Keywords: Biochemistry education; undergraduate students; protein models. ResumoAs proteínas são macromoléculas amplamente encontradas nas células e possuem inúmeras funções fisiológicas. Consequentemente, é fundamental construir um conhecimento sólido sobre estrutura tridimensional das proteínas. As estruturas proteicas são geralmente estudadas durante a graduação na disciplina de Bioquímica. Neste trabalho descrevemos intervenções pedagógicas planejadas para aumentar o conhecimento de estudantes de Química licenciatura sobre a estrutura de proteínas. As atividades foram realizadas utilizando materiais baratos para encorajar a sua implementação no ensino médio pelos futuros professores. A partir da estrutura primária da insulina, os estudantes construíram a estrutura tridimensional dessa proteína. Após as atividades, os estudantes destacaram uma melhora nos seus conhecimentos prévios sobre a estrutura das proteínas. A construção de um modelo tridimensional juntamente com outras atividades parece ser uma maneira eficiente de promover o aprendizado sobre a estrutura de proteínas aos estudantes de graduação. A metodologia utilizada foi simples e de baixo custo e pode ser utilizada tanto no nível universitário como no nível do ensino médio.
