THE EFFECT OF USING ANALOGY ON THE CONCEPT OF CHEMICAL EQUILIBRIUM ON STUDENTS’ ACHIEVEMENT AND ATTITUDE

Abstract

xv The Effect of Using Analogy on the Concept of Chemical Equilibrium on Students’ Achievement and Attitude ABSTRACT This study was aimed to evaluate the effect of analogy-based instruction on the concept of chemical equilibrium on Grade 11 natural science students’ achievement and attitude compared to the lecture method. The study consisted of 90 grade 11 natural science students’ (45 experimental and 45 control group students). The researcher used convenience sampling technique to select the sample students from the targeted school. Chemical equilibrium achievement test, cognitive retention test, interview, and student generated analogy work sheets were used for data collection. Both quantitative and qualitative data analysis techniques were used to analyze the collected data. The analysis result of pretest revealed that there is no significant difference observed between the two groups (at p>0.05) while significant difference was observed on the posttest between the two groups (at p<0.05). The experimental group students performed better on the posttest than the control group students. Moreover, the analysis of the data gathered through retention test and interview revealed that experimental group students have a positive attitude towards analogical instructional method. These showed that analogy approach helped students to integrate chemistry concepts with daily life and enhance their understanding, made concepts highly memorable, and create enjoyable learning environments.The analysis results showed that analogy instruction enabled students better understand the chemical equilibrium concepts compared to traditional instruction.
