This part will focus on the importance of student learning engagement, quality of instruction, and challenges of engaging students in large enrollment classes. 
Post-secondary classes with large enrollment present challenges for both students and instructors. Previous studies have explored solutions using active learning strategies and technologies to reduce students’ sense of passive participation and increase personalized feedback. Finding out strategies to engage students in large enrollment and content-heavy medical education classes, in particular, has been constantly in removing barriers for teachers and making learning more student-centered. Among these challenges and barriers has been the intensive student-content interaction which requires frequent practice and feedback. This is especially true in classes that have traditionally relied on textbooks of more than 600 pages with intensive terminology, anatomy images, and transition from lectures to student-centered learning. 
Pedagogically meaningful use of technologies in course design and teaching practices has been investigated as a potential solution to such challenges. Interactive learning objects have been used to provide a balance for students’ interaction with these medical instructional content and experiential learning. There are evolving attempts and instruments being developed to measure student perception of these ILOs. However, how student learning performance is affected by their perception of learning, quality of these interactions with learning objects, and their engagement with learning process was not much done in large-enrollment health sciences classes. This is the purpose of this study – To understand how student learning performance (as final grade of a semester) is related with perception of learning, quality of these interactions with learning objects, and their engagement with learning process.

Research Questions:
•	RQ1 – To what extent was student perceived learning affected by their perceived quality of these interactive learning objects (ILO) and their perceived engagement with these ILOs?
•	RQ2- To what extent were student final grades affected by their perceived learning, quality of ILOs, and engagement in this online class? 

Literature Review

This part will focus on the following areas:
•	Challenges of learning engagement and assessment for large-enrollment class, especially in medical education and with mandatory understanding of massive volume of medical terminologies
