Effect of collaborative concept mapping teaching strategy on students’ achievement in chemistry in selected secondary schools in Kenya
In Kenya, the fundamental challenge facing chemistry teaching in secondary schools is how to enhance students’ conceptual understanding; a need for meaningful learning. The challenge has led to students’ underachievement in chemistry in national examinations. Research findings indicate that teaching method is a crucial factor affecting students’ learning and achievement. The present study investigated the effect of Collaborative Concept Mapping (CCM) teaching strategy on students’ achievement in Chemistry. Solomon Four Group quasi-experimental research design was used in the study. Four co-educational secondary schools were randomly selected for the study from secondary schools in Bomet District, Kenya. Students in experimental groups were taught using CCM teaching strategy for 8 weeks while the rest were taught using conventional teaching methods. Mole Concept Achievement Test (MCAT) was administered to determine students’ achievement on the topic of “mole concept”. Results of the study showed that CCM as a teaching strategy had no significant effect on the achievement among students of low and average academic abilities as well as those of higher academic abilities at 0.05 α significance level.
