Effect of Computer Assisted Instruction (CAI) on
Secondary School Students’ Achievement in Science

Rabia Tabassum, Ph.D. and Rehmat Ali Farooq, Ph.D.

Abstract

Computer-assisted instruction (CAI) is an interactive instructional technique whereby a computer is used to present the instructional material and monitor the learning that takes place.

This study was designed to see the effect of computer-assisted instruction as a supplementing strategy on the academic achievement of secondary school students in the subject of science. The major objectives of the study were: (1) To find out the relative effects of computer-assisted instruction as a supplementing strategy on academic achievement in science; and (2) To investigate the difference between treatment effects on male and female students. To achieve the objectives of the study, the following null hypotheses were tested: (1) There is no significant difference between the mean scores of the students taught science with CAI as supplementing strategy and without CAI; and (2)

There is no significant difference between the mean scores of male and female students of experimental and control groups.

Secondary school students studying science subjects constituted the population of the study. The students of 9th class of The City School, H-8, Islamabad, were selected as sample of the study. Only students studying biology as an elective subject were included in the sample. Sample students were assigned to either the experimental group and or control group. Both the groups were equated on the basis of their achievement scores in previous semester in the subject of biology. Each group comprised 20 students.

There were two different treatment patterns applied during the experiment. Both the groups were taught through routine method by the same teacher. Computer-assisted instruction was used as additional strategy for the experimental group. During the experiment period, the experimental group received the treatment of. computer-assisted instruction whereby the students were exposed to certain web-cites consisting of drill and practice, tutorials, simulations and animation. Meanwhile the control group was kept busy in other activities such as guided practice and independent practice. This was adopted to control the variable of time and to realize the primary objective of the study. The experiment continued for six weeks. In order to find out treatment effects, a teacher-made post-test was administered to the experimental as well as control group immediately after the treatment (teaching) was over.

Significance of difference between the mean scores of both the groups on the variable of previous achievement was tested at .05 level by applying t-test. To see the treatment effects for male and female students both the groups, the factorial design (2 X 2 analysis of variance) was applied.

Analysis of data revealed that the students taught through computer-assisted instruction as supplementary strategy performed significantly better. Computer-assisted instruction was found equally effective for both male and female students.

1. Introduction

Computers are already in use in Pakistan in banks, large firms, transport companies, the armed forces and elsewhere. Either owing to excessive compartmentalization of administrative departments or to the relative order of political priorities, it did not appear that the Ministry of Education was ever involved at higher levels of decision-making. With the growing use of computers in education and instruction, computer training for teachers and teacher-educators is being considered a prime objective for the advancement of educational technology (Aubineau, 1986).
