Correct option is A
In the four-quadrant model of MOOCs, the third quadrant often focuses on activities and resources that support the content delivered in the main lectures. If Assessment and References are considered part of the third quadrant in the context of your MOOC model, then:
Assessment would typically involve various forms of testing, quizzes, and practical tasks that help evaluate and reinforce the learning from the course materials.
References provide supplementary material and sources that enhance understanding and provide additional depth to the course topics.
Thus, if this is the model and definition being used where Assessment and References are grouped together in the third quadrant, the correct selection would indeed be (a) A & B only. This combination supports the learning process by evaluating the learner's understanding and offering additional material for deeper exploration of the course topics.
Information Booster:
(b) B & C only and (c) C & D only: These options mix elements that generally belong in different quadrants; 'Video' is typically central to content delivery rather than supplementary or evaluative.
(d) B & D only: This option aligns with a common understanding of supplementary materials but does not include the evaluative component of assessments that is critical to many educational frameworks.
