The advent of computer in general and internet in particular has opened new avenues for learning language. Computer Assisted Language Learning (CALL) is considered highly effective for language learning as technology creates a student centered environment, increases learner autonomy, and results in higher learning outcomes. This study investigated if CALL using Web Based Instruction (WBI) as a tool is more beneficial than the traditional method for teaching English grammar to undergraduate students in Pakistan. An experimental design was followed to compare the effect of technology based and traditional method of teaching and a focus group interview was conducted to obtain the participants’ views about CALL. MANCOVA test was applied for the analysis of the pretest and posttest scores. Results showed that the experimental group performed significantly better than the control group. Additionally, the students exhibited a positive attitude towards technology based teaching. Based on these findings, integration of computers is recommended in English language teaching for improved learning.
