Using computer simulation to improve the teaching and learning of photosynthesis in two selected Junior High Schools

Abstract

The study investigated the use of computer simulation to improve the teaching and learning of photosynthesis in two selected Junior High Schools in Prestea Huni-Valley. The research was quasi experimental involving a pre-test and post-test. The total population of the third year Junior High School Students‟ was 2018 students. The sample for the study comprised 136 third year Junior High School students sampled from two public junior high schools in the Western Region of Ghana. The instruments used for the collection of data included students‟ knowledge of photosynthesis Test (SKPT) – pre-test and students‟ Achievement in photosynthesis Test (SKPT) –post-test, which were piloted in a junior high school in the Western Region. The students‟ post-test scores were subjected to statistical analysis using independent-measure t-test. The major findings of the study included: a significantly higher achievement of students exposed to the computer simulation instructional approach compared to those exposed to the traditional instructional approach, significantly higher achievement of the computer simulation instructional approach in cooperative learning settings than those in individualized learning settings. Based on the findings of the study, it is recommended among others that science teachers should employ innovative and more effective learner centered instructional strategies, such as, computer simulation instructional packages and organize their students into cooperative learning groups to promote meaningful learning of difficult concepts.
