Presentation tools and Pedagogy
  • Common Belief : Instructing using PowerPoint increases their engagement levels and increases student productivity
  • Research shows that difference in learning outcomes is often not significant
  • Studies have also shown that the learning benefits of presentation software can be greatly improved by enabling post-instructional access to the content of the presentation 

      • Not confident technology users
      • Lack of expertise with typing
    • Lack of sufficient time to prepare the content beforehand
