ABSTRACT
This study examined the effects of multimedia instructional strategies on chemistry students’ science process skills acquisition and achievement in Kano state. Six research questions and six null hypotheses guided the study. Researchers have revealed that students perform poorly in practical chemistry in spite of all that has been done to improve science teaching and learning in secondary schools. This situation could hamper their overall achievement in chemistry and therefore could cripple the realization of national goals for scientific and technological development. Literature has also shown that the use of innovative teaching methods such as multimedia instructional strategy could enhance science process skills acquisition and achievement in science, including chemistry. It is on this note that this study was carry out. The design of the study was quasi-experimental, specifically pre-test, post-test, non-equivalent control group design. A random sampling technique using balloting method was used in selecting three public senior secondary schools out of the sixty-five (65) secondary schools in Nassarawa Education Zone because of the experimental nature of the study. Eighty-one (81) students were used for the two experimental groups and thirty-nine (39) students were used for the control group. All the groups were intact classes. The instruments used in data collection are science process skills acquisition test (SPSAT) which is designed to assess the level of students’ science process skills acquired in qualitative analysis and qualitative analysis concepts achievement test (QACAT) which is to measure the level of knowledge attained in qualitative analysis concepts in chemistry. The instruments were validated by experts in chemistry education and measurement and evaluation based on content coverage, clarity, non-ambiguity, relevance and to the level of the students’ knowledge. Split half reliability technique was used to estimate the reliability coefficient of SPSAT. The scores were correlated using Pearson product moment correlation analysis and found to be 0.79.On the other hand, the reliability coefficient of QACAT was calculated using test, retest procedure of two weeks interval. The scores of the two tests were also correlated using Pearson product moment correlation and found to be 0.88. The data collected were analyzed using mean, standard deviation, t-test, analyzing of covariance (ANCOVA) and Scheffe post hoc test at 0.05level of significance. The findings of this study revealed that multimedia instructional strategy improved both the acquisition of science process skills and academic achievement better than the conventional laboratory method. The study also found that there is statistically significant difference between the two experimental groups. However, there was no significant difference across gender in the acquisition of science process skill. The following recommendations were made among others: The government at all levels should recruit qualified chemistry teachers and train them in the use of multimedia facilities such as computers, projectors, softwares, internet, video tutorials, e.t.c.,The curriculum planners and curriculum development bodies in Nigeria such as NERDC should revisit the chemistry curriculum with a view to design programme and policies that will incorporate the use of video-based and web-based multimedia strategies in teaching and learning of sciences at senior secondary school level.
