The Effects of Microcomputer-Based Laboratory on Students’ Macro, Micro, and Symbolic Representation in Learning of Net Ionic Reaction

Abstract

This study used graphs of conductivity measured by Microcomputer-based laboratory (MBL) to promote students’ macro, micro, and symbolic representation in learning of net ionic reaction (NIR). A total of 54 students, aged 14-15 years old, participated in this research, and were randomly divided into an experimental group (N=27) and a control group (N=27), respectively. The treatment in the experimental group was the graphs of conductivity measured by MBL, while the treatment in the control group was the demonstration of acid-base titration experiment. Results revealed that the graphs of the conductivity has a large effect on students’ macro, micro, and symbolic representation, that is, the students in the experimental group build more representations than the students in the control group.
