Errors Are Necessary for Learning

About this video

In this short clip, Dr. Alan Castel argues that good learning happens through making mistakes, not repeated viewing. People have seen the Apple logo countless times, Castel notes, yet are unsure whether the bite is on the left or right or whether there is a stem or leaf. He says drawing it from memory and struggling, then seeing it again, engages better learning.

Key takeaways

• Dr. Castel argues that making mistakes during retrieval produces better learning than repeated viewing.
• Castel uses drawing the Apple logo from memory as an example of errorful learning.
