Instructional Ideas
  • Use editing software such as EdPuzzle to insert questions periodically throughout the video for pupils to complete
  • Post the video as a resource for absent class members or those that need extra instruction
Classroom Considerations
  • Requires Internet access to watch YouTube videos
  • The method used for finding (h,k) is abstract; this may not be the typical method pupils learn
  • The lesson is 13th in a series of 29
Pros
  • The author uses multiple methods to accomplish the goal of graphing the quadratic function
Cons
  • The lesson does not connect the graph to the transformations from the parent function
