THE EFFECTIVENESS OF STRUCTURED INQUIRY BASED MODULE TO IMPROVE MENTAL MODEL OF CONCEPT MOLE

Abstract

Mole concept is the essential part of chemistry learning and has been the prerequisite to learn other chemistry concepts. Learning source used has not yet connected the three levels of representations completely. The inability to connect the three levels of representations might affect students’ learning outcome and mental model. This study aims to find out the effect of structured inquiry based module on students’ mental model of mole concept. The design of study is Randomized Control Group Postest Only Design. There were 141 students from two Senior High Schools in Padang recruited as the samples of study. The instruments are two-tier mental diagnostic test and semi structured interview. The result of t-test on hypotheses reveals that the mental model of mole concept in experimental group was higher than that of control group of both schools. Hence, it can be said that there is effect of module on students’ mental model of mole concepts in both schools
