Enhance learning outcomes

• I am able to recall procedures better with the help of simulations (T05, male).

• I like the interactive activities in personal protection because I can experiment until I get it right (T05, male).

• Practicing in the self-assessment module helps me consolidate my knowledge (T14, female).

Well-organized and effective structure

• After I have completed the content and practice module, I can assess my understanding of them by taking a self-assessment. This way I can ensure that I have mastered the material before moving on (T2, female).

Clarity and ease of understanding

Perceived ease of use

• With clear instructions and assessments, I progress from step to step through a structured learning experience (T08, male).

Intention to continue using it

• I will keep using WeMed to further enhance my knowledge and skills in lab safety and emergency procedures (T12, female).

Technical suggestions

• It will be easier for me to remember and understand if it is organized through mind maps (T02, female).

• I recommend incorporating a progress bar to present the completion percentage (T06, female)
