ABSTRACT
The study was carried out to examine the effects of electronic instructional medium on secondary school students achievement in aquatic animals of biology content. Specifically, the study focused on investigating the effect of developed video DVD instructional package on students’ achievement in aquatic animals of biology content, and the effect of developed Video DVD instructional package on gender in aquatic animals of biology content. The quasi-experimental, pretest-postest control group design was used in the study. The sample comprised of 200 SS2 students from four secondary schools located in Gusau metropolis, Zamfara state. The subjects were divided into an experimental group (electronic medium instruction) and a control group (traditional lecture instruction). Structured Biology Achievement Test (SBAT) with internal consistency reliability co-efficient of 0.83 was used to measure the student’s achievement before and after the treatment. The data obtained from the study were analyzed using Analysis of Covariance (ANCOVA). Results from Means, Analysis of Covariance (ANCOVA) and Scheffe test indicated that the achievement of students in aquatic animals of biology content greatly improved with the use of electronic instructional medium. Also, students’ gender had no significant effect on their achievement in aquatic animals of biology content when electronic medium was used. The study therefore recommended that secondary school biology teachers should effectively make use of video tapes/DVD in teaching the students irrespective of gender. More so, qualified teachers who are already in the field and are not knowledgeable in the act of production and use of various instructional media should be re-trained through seminars, workshops, conferences and in-service programmes. The teachers who are still on training in various teacher training institutions should be exposed to educational technology courses to equip them with skills needed to face the challenges of inadequate or lack of instructional media prevalent in Nigerian schools.
