Evaluation of a medication calculation mobile app using a cognitive load instructional design

This study indicated that the app's instructional design, based on cognitive load theory, significantly improved students' medication calculation ability and self-efficacy. Although the app's usability was highly rated by the students, further research is needed to determine if the app's instructional design can be used by learners of different levels of expertise and whether the design can be adopted for the learning of other complex cognitive skills. As numerical ability is essential for medication calculation ability, early identification and rectification of any numerical deficits is recommended.
