Teaching Practice and Evaluation Using Teaching Materials of Digestion of Proteins and Lipids

Abstract

Teaching practice incorporating experimental teaching materials for digestion of proteins and lipids was done for an "Animals' bodies and their functions" unit of the science class of the second school year in lower secondary school. Results clarified the following. (1) The class incorporating the experiment stimulated the students' interests. They gave a roughly affirmative evaluation. Students who had conducted the protein experiment, which more emphasized that "The protein and lipids were digested in this experiment using a digestive solution", evaluated the teaching more highly than the students who conducted the experiment on lipids. However, many students felt that the experiment method and the operation were difficult for them. Especially difficult was an operation of the amount of the scale using a Komagome pipette. Therefore, improvement is necessary, such as that through simplification of the experimental method, etc. (2) A class incorporating the experiment for digestion of proteins and lipids can be practiced merely given a room in which to learn progressive contents and a few spare hours.
