In a study of the learning effects ofa computer-based module on the topic of control systems10, the researchers found greater gains atlower cognitive levels of Bloom‟s taxonomy11 (Level 2: Comprehension; Level 3: Application) Page 22.1619.3than at higher levels (Level 4: Analysis; Level 6: Evaluation).

defined self-regulated learningas “learning that results from students‟ self-generated thoughts and behaviors that aresystematically oriented toward the attainment of their learning goals” (p. 125). In addition,Bandura9 showed that self-efficacy beliefs impact performance because these beliefs representpeople‟s perception of their capabilities to perform a task at designated levels. These researchershave provided empirical data on causal or correlational relationships between self-efficacy andepistemic beliefs and self-regulated behaviors and performance in subjects such as mathematics5,10 .During problem solving, students assess the difficulty of the task while disambiguating theimportant from irrelevant information.

The preliminary data obtained in this study from the first round of PBHimplementation is encouraging considering these experiments were devised and completed bythe students using simple objects and items while in the middle of the COVID-19 pandemic. Theauthors will continue their efforts in improving the PBH implementation process in future studiesthrough the above mentioned measures to enhance student learning and student success rates inthe Dynamics course.References[1] S.
