However, research into the nature of the learning process has thrown some light on what happens inside the ¡®black box¡¯. This has enabled educational technologists to structure the input (teaching methods, curriculum, educational aids, etc.), to systems of this type in such a way that optimal assimilation of the knowledge and skills takes place during the learning process, hence maximize the quality of the output. Teaching method is one of the most important inputs to the teaching learning process which can be structured in various ways and with different dimensions. This study examined the effect of computer aided instruction on student achievement in educational research and statistics course as compared to traditional method of instruction. An experiment was conducted with the students of three different programs of session 2009-2010 studying at Islamic University of Technology (IUT). The study was conducted using post-test only equivalent group design with matched groups based on grade point average of the winter semester of the academic year 2009-2010. Perfectly matched fourteen pairs of students were selected and assigned randomly to the experimental and the control groups. Students of the experimental group received computer aided instruction, for a period of eight weeks in the form of presentation and tutorials and the control group was taught through the traditional method of instruction. Two null hypotheses were tested by analysing the data on achievement test. The results revealed that the experimental group outperformed the control group and there was no significant difference in the overall mean achievement scores of the three subgroups of the experimental group. The main objective of this study was to develop a well-structured computer aided instructional package for educational research and statistics course so that the learners both students and teachers can understand the theory and at the same time implement the theory into practice. %K Computer Aided Instruction (CAI) %K Traditional Method of Instruction (TMI) %K Student Achievement %U www.ijcsra.org
