The use of technologies for encouraging student participation and engagement in lectures is often advocated by many academic practitioners. The Student Response System (SRS), colloquially known as ‘Clickers’, has been used in many academic institutions. There are some evidence that it contributes positively to students' learning, engagement and interaction in lectures. The aim of this study is to highlight Computer Science students' opinion on using SRS, and its contribution to their learning and engagement in lectures. We report our finding on students' opinion of using this teaching and learning technology. Moreover, we found different effect of this technology on students' engagement in lectures, peer learning, and knowledge acquisition. Based on students' feedback, we draw our conclusion on using this technology by suggesting some ways for improving its use according to students' views and feedback.
