Lipids and proteins: worksheets, concept maps and safe experiments

Popis výsledku v původním jazyce

The purpose of this paper is to describe the possibilities of using worksheets in the teaching of lipids and proteins. The worksheet includes a concept map, suggestions for three safe experiments that can be performed with available household chemicals, and observation results. The worksheets were implemented into action research in two classes taught by the same teacher. The verification of the worksheets took 90 minutes. First, the students filled out the prediction cards, structured the concepts related to the topic of the worksheet, verified the worksheet, wrote the results of the verification, and finally, after performing the experiments, filled in the prediction cards again. It was found that students have a problem with the interpretation of the data and many of them lack the skills needed to carry out the experiment. The knowledge at the beginning and at the end of the lesson was verified by deciding on the truth of the statements on the prediction card. The input knowledge of lipids and proteins was 66% identical, while the output knowledge of lipids was 81% and proteins 91%. The combination of work with a conceptual map and the implementation of experiments led to the consolidation of knowledge in these two thematic units of biochemistry.
