This study was designed to determine the effects of computer-assisted instruction (CAI) on the achievement level of college students in trigonometry, University of Nueva Caceres , City of Naga , Second Semester, S/Y 2000-2001. Specifically, this study sought to answer the following questions: 1) What is the level of achievement of the experimental and control groups based on the pre-test results? 2) What is the level of achievement of both groups based on the post-test results? 3) Is there a significant difference between the achievement of the experimental and control groups based on the pre-test and post-test results?
This study used the quasi-experimental method using a total of 50 students as the student-respondents. A teacher-made test was used to determine the mathematical achievement of the students in three skills: computations, comprehension and analysis skills.
Major conclusions of the study were: 1) The achievement of both the experimental and control groups in the pre-test was below average. 2) Post-test results on achievement level of the experimental group were outstanding; whereas for the control group, the achievement level was above average. 3) Based on the pre-test no significant difference was found between the experimental and control groups which showed the computed t-value was less than the tabular value; however, the post-test results showed a significant difference between experimental and control groups where the computed t-value was greater than the tabular value; furthermore, the computed t-value of the mean gain was greater than the tabular value.
