Abstract

This study aims to analyze middle school students' systemic thinking to express organic relations between different organ systems about the movement of food and air and teachers' reflective thinking about science teaching through their reflective journals after the lesson of digestion, circulation, respiration and excretion. Firstly, when investigating the moving route of hamburger eaten inside the body, students expressed the names, locations and forms of organs in the digestive system more than those in the circulatory system or the excretory system. When investigating the moving route of a painkiller taken inside the body, students seemed to have more difficulty in expressing the related organ systems than when investigating the moving route of other things, and they mostly drew pictures of organs in the digestive system as done for the moving route of hamburger. However, when investigating the moving route of water drunk inside the body, students mostly described organs in the digestive system but drew more pictures of organs in the excretory system, than when investigating the moving route of other things. When investigating the moving route of air inhaled inside the body, students mostly drew pictures of organs in the respiratory system, but the rate of their drawing pictures of circulatory organs was low. Secondly, this study analyzed one of the teachers' reflective journals, named Mr. Park. According to his journal, students showed different levels of understanding of organ names, depending on their degrees of familiarity with each organ, and in regard to the locations of organs, science teachers mostly aim to achieve learning objectives so much that they often forget to instruct the locations of organs in fact. As for the forms of organs, science teachers mostly spend so much time explaining the functions of organs that they often forget to describe the exact form of each organ.
