Balancing chemical equations is difficult even for top learners, and oxidation-reduction reactions can be the most difficult to understand. Using the half-reaction method, the instructor demonstrates four examples. Learners can watch the video again and again until the process make sense.

Instructional Ideas

• Assign the video as homework and use class time to practice similar problems
• Pause the video after each example to answer questions and clarify the procedure

Classroom Considerations

• Ensure learners have access to the Internet if assigning as homework

Pros

• Video includes a good mix of problems to demonstrate different scenarios that may emerge when balancing redox reactions
• Uses a consistent strategy for all four problems, allowing scholars to transfer knowledge to different types of problems

Cons

• The writing is sometimes cramped and difficult to follow
