Abstract in brief

  • Learning isn't just about getting the right answers; it's also about how you study and test your knowledge.
  • In a study, students learned vocabulary through various methods: some tested and studied repeatedly, while others had different combinations of study and testing.
  • The findings showed that repeated testing significantly improved long-term recall, while additional studying after learning didn't help.
  • Interestingly, students often misjudged their performance predictions, highlighting a gap in their understanding of effective learning strategies.

@Ylan Det finns forskning som visar att repeterad testning är överlägset som inlärningsform. "Retrieval" kallas det - att plocka upp saker ur minnet, vilket förstärker just minnet och förankrar det https://t.co/lf7JCvKPpU
