Instructional Ideas

• Create more guided practice problems to help explain the concept
• Flip the lesson and have viewers watch the video outside of class, saving class time for practice of the skill

Classroom Considerations

• Remember anyone can submit a comment on YouTube 
• Requires prior knowledge of electron dot structures

• This video is hosted on YouTube

Pros

• Solves the example step by step

Cons

• Explanation is not clear
• Presentation is not engaging and may not hold pupils' attention
