Learning Pathways In Organic Chemistry
Textbooks are filled with guides, flow-charts, approaches, patterns, pathways, etc that will lead to the correct answer if followed by the learner. Unfortunately, many learners fail to accumulate this knowledge at the appropriate time in the learning process. Online exercises that require students to use these learning pathways have been developed by Chem21Labs for both General Chemistry and Organic Chemistry.
Two import concepts in the Organic Chemistry curriculum that lend themselves to "Learning Pathways" are drawing resonance structures and writing mechanisms. Chem21Labs has developed HTML5-JS interactive animations that can be assigned (and reassigned) where students draw curved mechanism arrows to create resonance structures and reaction mechanisms. These animations teach students how to "push electrons" . . . . . as these animations are re-assigned, this knowledge is "maintained" in the student's long-term memory.
