The Shift blog regularly has some very interesting posts, and this article is one of my favorites. Comparing Typical (Crammed) Learning vs Spaced Learning addresses an important concept in the way people learn, especially as it relates to adult learners in the workplace … when they are trying to learn and improve their on-the-job work performance.
Crammed learning (e.g., massed learning, blocked learning) tends to be effective in “learning” information in the short-term (like cramming the night before for a test) but spaced learning is better for more long-term, workplace type learning. Spaced learning, similar to the practice of “interleaved learning“, has proven to increase learning and performance while also fending of the “forgetting curve”.
Read this article for reasons and suggestions on how you can (and should) include spaced learning techniques into your instructional design; you owe it to your learners!!
