A Model-Based Inquiry Activity Using LEGO to Promote System Thinking of Grade 11 Students on Buffer Solution Topic

Abstract

System thinking in chemistry education aims to prepare future students who can relate the chemistry knowledge addressing real-world complex phenomenon and having more holistic perspectives. The system thinking skills are divided into three levels: (1) analysis of system, (2) synthesis of system, and (3) implementing knowledge to the real-world issue. In this study, a model-based inquiry learning activity using LEGO was developed to promote students’ system thinking on buffer solution topics. In the activity, LEGO was used as a tool for students to simulate systems for representing the pH controlling process in related natural phenomena such as Maintaining the pH of seawater, the circulatory system, and the food industry, etc. The activity was implemented to 30 Thai high school students in the science and mathematics program using a one-group pretest-posttest design. A test on system thinking specific to the buffer solution topic and a student's self-evaluation questionnaire on system thinking skills were used as tools for collecting data. An analysis of the three levels of system thinking skill showed that the average posttest score of each level was significantly higher than the pretest score in all levels especially in implementing knowledge to the real-world issue. After the activity, students’ reports from the questionnaire indicated that they could relate each component in systems and could elaborate their knowledge to other systems.
