ABSTRACT
The purpose of the study was to determine the effectiveness of problem-based learning (PBL) approach to mole concept among students of Techiman Senior High School. The study was quasi-experimental research and nonrandomized control group pre-test – post-test design. The total population considered for the study was 243 second year students of Techiman Senior High School. The sample size was 74 second year students offering the General Science Programme. The selection procedure was nonrandomized. Intact or already existing classrooms were used for the study. The control group consisted of 37 second year students and the experimental group was equally 37 second year students as this arrangement was the prevailing situation in the two intact classes at the time the study was conducted. In the experimental group, the Problem-Based Learning (PBL) approach was used while the Traditional Lecture-Based (TLB) method was used in the control group. The instrument used in the study was the Mole Concept Achievement Test (MCAT) which took the form of pre-test and post-test. The reliability coefficients were found to be 0.736 and 0.751 for the pre-test and post-test respectively. Data were analysed using ttest and bar charts. The results of the study revealed that the PBL resulted in significantly higher students‟ achievement in mole concept than the TLB.
