Lyndon McErlaine found 60 Second Histories:

• Significantly builds student knowledge“Students find it easier to recall events as this gives them a hook. Also, this method is often a useful way to launch a topic.”
• Significantly improves teaching efficiency and productivity“The range of Kevin’s characters is so vast, I believe that most areas are covered. The library saves time for me to search for something.”
• Moderately saves school money“Time is one. The amount of time saved is invaluable. Also, we purchase fewer expensive textbooks.”
