Improving the performance of students in volumetric analysis through concept mapping in Wenchi Senior High School

Abstract

The study investigated the use of concept mapping teaching method on Senior high school students’ academic achievement in chemistry. The design of the study was quasi-experimental design with 54 elective science Senior High students selected purposively from Wenchi Senior High School in Brong – Ahafo Region. Twenty – seven (27) students were used for both the control and experimental groups. Experimental groups were taught using concept mapping teaching strategy while Control groups were taught using the Traditional Teaching Method .The study was conducted within six weeks period and the topic covered was volumetric analysis. The students were pre-tested and post-tested using a Tutor Constructed Chemistry Achievement Test (TCCAT). Instrument used for data collection was an achievement test tagged Tutor Constructed Chemistry Achievement Test (TCCAT). The content of the instrument was validated by three experts and Cronbach alpha formula was used to test its reliability. The reliability coefficient of 0.82 and 0.75 for pre- test and post- test respectively. The data from both pre and post tests were analyzed using methods of descriptive and inferential statistics. The statistical procedures employed were: student t-test analysis as well as descriptive statistical tool such as the mean, standard deviation etc. to determine the impact of concept mapping on students’ performance in volumetric analysis. The responses from the questionnaire items were analyzed through the use of descriptive explanation making use of averages, percentages and descriptive statistics such as means, and percentage scores were calculated for participants’ responses.
