To engage learners effectively, integrate a drag-and-drop activity into the online learning module as a knowledge check. By dragging and dropping items or concepts into appropriate categories or sequences, learners are prompted to demonstrate understanding and make cognitive connections between different pieces of information. This tactile interaction enhances engagement by providing a dynamic and immersive learning experience that stimulates critical thinking and problem-solving skills. Additionally, the immediate feedback inherent in drag and drop activities reinforces learning outcomes, as learners receive instant validation or correction of their responses.
