Electrochemistry is found to be a difficult topic to learn due to its abstract concepts that involve three representation levels. Research showed that animation and simulation using Information and Communication Technology can help students to visualize and thus enhance students' understanding in learning abstract chemistry topics. As a result, an interactive multimedia module with a pedagogical agent (IMMPA) named EC Lab was developed to assist students in the learning of Electrochemistry. There were 35 students and seven experts involved in this formative evaluation to test the usability and effectiveness of the module developed. Instruments involved were module evaluation questionnaire, module reliability questionnaire, module validity questionnaire, pretest, post-test and motivation questionnaire. Results showed that the students and experts rated the module developed as high (M = 3.94) and very high quality (M = 4.45). Besides, the respondents also see the module as reliable (M = 3.87) and valid (M = 4.51). Students have higher scores on their post-test and have gained higher motivation level after learning with the IMMPA EC Lab. However, some corrections and modifications have been made based on feedback and suggestions from the respondents to improve the quality of IMMPA EC Lab.
