The study focused on seven (7) task-based activities, including (1) making film, (2) making portfolio, (3) group presentation, (4) library search, (5) paper display, (6) making a gift, and (7) literary gala which was applied in two British-American Literature courses such as Introduction to Literature and Introduction to Literary Criticism. A thirty-threeitem questionnaire was administered to investigate the effects of those task-based activities on students’ involvement. The interviews for students and teachers were employed to examine students’ perceptions of their involvement in those task-based activities and discover teachers’ observations of students’ involvement in their class. The study sample consists of 120 EFL high-quality students who have taken the two courses of Introduction to Literature and Introduction to Literary Criticism in their curriculum. The findings revealed that students were involved in task-based activities to a significant extent and students had positive perceptions toward their task-based performances. There found a medium correlation between the extent of task-based activities' impacts on students' involvement and students’ perception of their involvement. The crosstabulation signified that the Introduction of Literature course required students to do more taskbased activities than the Introduction to Literary Criticism course.
