Impact of Integrating Basic Science Process Skills on Students Performance in Biology Practical in Vihiga County, Kenya

Abstract

The study investigated impact of Integrating Basic Science Process Skills on students’ performance in Biology practical. Research study objective was to determine students level of mastery of Basic Science Process Skills in learning of Biology practical. Form Three students were involved in the study. The study adopted Constructivism theory and Quasi experimental research design. Data was collected using Biology Achievement Test. The tests consisted of both pretest and posttest. The students target population was 4560 Form Three students. A sample size of 384 Form Three students was obtained from the target population using Yamane’s formula. Twelve participating schools were selected by applying Stratified and Simple random sampling method. Six experimental and six control group of schools were created using Purposive sampling method. Experimental group were taught using practical activities while control group focused on teacher centered activities.  Data was analyzed using Statistical Package for Social Science version 27. Descriptive statistics was used to analyze mean, standard deviation and median. Inferential statistics were used to determine significance of results. Content validity was determined by piloting the study instruments. Internal consistency reliability of the tests was determined using Kuder-Richardson 20 formula (=.978). A two-way ANOVA indicated that there was a significant difference in learners’ performance in Biology practical in both experimental group and control group at p<.05.
