The current study measures the extent to which students' self-regulated learning tactics and learning outcomes change as the result of a deliberate, data-driven improvement in the learning design of mastery-based online learning modules. In the original design, students were required to attempt the assessment once before being allowed to access…

Presented three algorithms to university students in an introductory laboratory chemistry course and found that differences in the effects of representation modes--flow charts, lists, and standard prose--were complex and changed over 10 lab sessions. There was no evidence that representation mode affected critical thinking ability or final grade.…

Compares performances of students on gas-law problems that require two distinct approaches, either the algorithmic technique or the conceptual gestalt. Indicates that student effectiveness is considerably different utilizing each approach and that training or experience with the algorithm process should not be expected to facilitate the…
