In modern language teaching institutions and schools, the proficient language teachers apply different kinds of tasks to teach some skills and sub-skills. In the current study, the researcher investigated the effect of two different tasks, namely Computer Assisted Language Learning (CALL)-based tasks and written questions tasks on students' English grammar learning. The researcher in the control group asked the participants to answer the written questions in their workbooks and the participants in the experimental group do their assignments using the computers. Based on the post-test results, both CALL-based and written question tasks had positive effects on the participants. The study supports the idea that motivating tasks can have positive results toward language learning.
