Effect of the Use of Visual Aids on Form Two Pupils' Performance on Blood Circulatory System in Humans at Don Bosco Catholic JHS

ABSTRACT

The purpose of the study was to determine the effect of using visual aids as an instructional tool in the teaching of circulatory systems in humans on the performance of Junior High School students. It further investigated the students‟ perception of motivation about their integrated science classroom learning environment under the visual aids and traditional teaching approaches. The study employed quasi experimental design. Purposive sampling technique was used to select the two schools for the study. The sample size comprised 81 students with 39 of them in the experimental group and the remaining 42 students in the control group. The experimental group was instructed using the visual aids method while the traditional lecture approach was used for the control group. Pre-test and post-test were carried out simultaneously on both groups using teacher-made achievement test. An independent sample ttest and paired sample t-test were used to analyse the scores of the achievement test. The findings indicated that students in the experimental groups achieved better results compared to those in the control group. Also, the results indicated that there was statistically significant difference in the Science achievement mean scores between the male and female students when taught with Visual aids as an instructional tool. It was also realised that students taught with visual aids were more motivational in learning the blood circulatory systems in human than the traditional method of teaching. It was recommended that teachers should incorporate the use of visual aids in the teaching of Science.
