摘要：Physics is a science subject that has contributed immensely to the technological advancement of the world. In the Kenyan 8-4-4 curriculum, it is optional at form three and four. However, physics in Kenya has been faced with poor performance. Consequently, many students drop out of the subject on moving to form three. The cause of this trend has not been fully concluded. On the contrary, many have attributed it to poor instructional methods. This study, therefore, attempts to change this trend. It collected data on the effects of Gowin’s Vee heuristic strategy on students’ conceptual understanding and metacognition in physics among secondary schools in Uasin Gishu County. It was carried out in physics classroom setting. Solomon four quasi-experimental design was used. Two experimental groups were taught using Gowin’s Vee as treatment and two control groups were taught using conventional methods. The target population was 3735 form two students in 83 mixed secondary schools in Uasin Gishu County. Purposive sampling was used to select 134 students to the control and experimental groups. The instruments used were Physics Metacognitive Activity Inventory Questionnaire (PMCAIQ) to test their metacognition and Physics Conceptual Understanding Achievement Test (PCUAT) to test conceptual understanding. The validity of the instruments was determined by supervisors and examination experts from the department of Curriculum, Instruction and Educational Management as well as physics teachers. Reliability of instruments was done using the coefficient of alpha for both instruments. The study found Coefficient of alpha 0.75 and 0.78 for PCUAT and PMCAIQ respectively, hence they were reliable. The data was subjected to descriptive statistics such as mean and standard deviation. Also inferential statistics was done using t-test and one way ANOVA at 0.05 significance level. These were followed by post hoc analysis. The analysis was done by Statistical Packages for Social Sciences (SPSS). This study is important in enhancing performance and quality of teaching in the topic of moments in physics and sciences in general.
