This course intends to encourage the study of the chemical structure and function of biomolecules using lectures and practical classes. Looking at the evaluations from previous semesters, it became evident that the subjects of the membrane and extracellular matrix were not being learned in a meaningful way. We also noticed lack of motivation from students due to difficulties in understanding molecules, weakening the teaching/learning process. Given this situation, our work aimed to encourage students to construct the constituent molecules of the membrane and extracellular matrix and assemble these structures, in order to understand molecular interactions, improve understanding of the subject and facilitate the learning process. This was accomplished through a monitoring project with the help of monitors. The proposed methodology consisted of separating the class into groups, where each would be responsible for making and exposing the other students to one of the molecules (Membrane Lipids, integrins, fibronectin, collagen, elastin, laminin, hyaluronic acid), and then discussing these molecules’ structural characteristics and interactions. The students could use various types of materials like cardboard, colored pens and polystyrene. The molecules were presented to the class, and the groups had set up the membrane and the matrix indicating the location of molecules and their possible interactions. All groups created their molecules according to given specifications. They created didactic and colorful molecules and positively interacted with all other groups during the assembly of the membrane and extracellular matrix; they also discussed molecules functions and interactions. We noticed during presentations and evaluation a strong performance in the subjects in question, as well as the construction of a didactic model easily used to understand these subjects; we therefore postulate that the activity achieved its objectives.","PeriodicalId":185758,"journal":{"name":"Journal of Biochemistry Education","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130488154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Enable all children to acquire the problem-solving, thinking, and communication skills of scientists – so that they can be productive and competitive in the new world economy. 2. Generate a “scientific temper” for each nation, with scientifically trained people in many professions, ensuring the rationality and the tolerance essential for a democratic society. 3. Help each nation generate new scientific knowledge and technology by casting the widest possible net for talent. My preferred strategy for the United States: 1. Science education should have a much larger role in all school systems, but only if this science education is of a different kind than is experienced in most schools today. 2. Making such a change will require a redefinition of what we mean by the term  “science education”. 3. To create continually improving education systems, we will need much more collaborative, effective, and use-inspired education research - research that is focused on real school needs and that integrates the best school teachers into the work. 4.

Objectives: We investigated the impact of different kinds of visualization on student’s accomplishments, and the relationship between 2D and 3D visualization on the learning outcomes in biochemistry teaching, as well as gender-related differences in 2D vs 3D perception abilities. Materials and Methods: The research study was conducted on a sample of 149 senior secondary school students, devided into three groups: control group (usual teaching approach), and two experimental groups taught using different kinds of visualization: E1 (2D and 3D static visualization tools), and E2 (3D dynamic visualization tools, in addition). Discussion and results: We measured the students’ learning outcomes in biochemistry, as well as the level of satisfaction with different teaching methods. The data were interpreted by performing statistical measures and analyses. In order to validate our hypothesis, we used one-tail and two-tail ANOVA analyses (along with the t-test). Conclusions: There was no statistical significance regarding 2D vs 3D visualization tools in biochemistry teaching. Although there existed some gender-related differences in students’ achievements (in favor of females), it was not established that they were related to the type of visualization (2D or 3D) tools applied. However students from the E2 group (additional computer animations) were more interested and involved in this kind of teaching. Although the results do not show a statistical significance in favor of 3D visualization, we must conclude that in teaching biochemistry it is certainly a more efficient approach than traditional teacher-oriented lessons. By using this kind of visualization tools in everyday teaching practice, chemistry teachers are given the opportunity to enlighten students with somewhat complex and abstract biochemical concepts.","PeriodicalId":185758,"journal":{"name":"Journal of Biochemistry Education","volume":"6 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128248975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The digital games feature a playful and motivational character that encourages students during the concepts learning, with a different way to learning the concepts studied. Objectives: The objective of this study was the development of a computer game focused on the concepts of ATP formation, including the glycolytic pathway, Krebs cycle and Electron Transport Chain, as well as aspects related to the regulation, and evaluate the usability of it, as well as some evidence of its educational potential. Material and methods: The development of the game followed the following steps: definition of the subject; understanding of game developer (it was chosen the GameMaker); storyboard creation of the game; prototyping, implementation and usability testing. For the evaluation, inspection usability was performed (without involving end users) and subsequently the cognitive route and the usability questionnaire (the latter two with students of the discipline of Biochemistry). Results: The game approached the energy metabolism in three phases: the glycolytic pathway, Krebs cycle and electron transport chain. Each phase has a different purpose, with some questions about the ways. To complete the game, you must correctly answer the questions, avoid the obstacles and achieve the goals of each phase. After usability testing, it found that users could, in a playful manner, actively interact with the content addressed and, through the difficulties presented in the game, had the opportunity to expand and review their knowledge. Conclusions: The game was identified as a motivating and innovative proposal for  teaching, and it had good usability for undergraduate students. The ludic worked as a pedagogical practice encourages student for learning and may assist in the construction of knowledge.","PeriodicalId":185758,"journal":{"name":"Journal of Biochemistry Education","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116942876","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study was to investigate if an interactive didactic model, crafted with simple materials, could facilitate the understanding and learning of students on photosynthesis. Initially students of first year high school class from a public school Western of Parana were asked to diagram what they knew about photosynthesis and respond to a questionnaire. It was concluded that many of the students’ prior concepts were general or inaccurate, such as the idea of photosynthesis being the process of respiration in plants, and O 2 coming from the CO 2 , not from the photo-oxidation of water. These prior conceptions were important for planning the approach to the subject. The process of photosynthesis was then covered in lecture and dialogued, using the interactive didactic model to highlight the explanations. A new questionnaire was completed by the students, and concluded that the use of the interactive didactic model was efficient, since it helped to consolidate correct concepts and simultaneously, introduced new ones as well it shook the equivocal relations.","PeriodicalId":185758,"journal":{"name":"Journal of Biochemistry Education","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114547973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

How to calculate the volume of an egg? Because the rotten egg float? Why has this characteristic rotten egg smell? Because the gray-green color is formed on the surface of the cooked egg yolk? These issues are commonplace and unnoticed in day-to-day. Our grandmothers know how to tell if an egg is rotten or not, you just put the egg in a glass of water. If it is rotten floating, sinking is good. But why this happens? That they do not know answer. With only one egg chemical reactions work, macromolecules (proteins), density, membranes and conservation of matter. Hydrogen sulphide is responsible for the aroma of a freshly cooked egg. This gas as they break down the molecules of albumin, a protein present in the egg is formed. The color comes from a sulfide precipitation, this time with the Fe2+ ion contained in the yolk (Fe2+ + S2  FeS). The use of simple and easy to perform experiments, correlating various knowledge proves a very useful tool in science education. Objectives: Develop multidisciplinary learning contents through the problem. Materials and methods: The teacher provides students with a boiled egg, salt, a syringe and a cup, a plate and water. The teacher lays the aforementioned issues for students and allows them to exchange information with each other, seeking answers through experimentation. Results and discussion: Students engaged with the activity and interaction of groups in order to solve the proposed problem. Still, through trial and error have sought in various ways to find the answers. This tool takes the student to be active in the teaching process, making him seek answers in their acquired knowledge in other areas. We believe that the collective construction of knowledge was significant for students' learning, which can be proven by the constant reminder of concepts worked. Conclusion: The tool fosters the development of the methodology of questioning, making the subject active learner in the learning process. So, being a model for other future work activities with specific concepts. And another point to be considered is the introduction of students in scientific methodology.Keyword: classroom practice, questioning the methodology, experiments with eggs.","PeriodicalId":185758,"journal":{"name":"Journal of Biochemistry Education","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125447203","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
