Question: I am interested in how to improve a students length of concentration and resilience to keep on a topic for longer. Any ideas?

Hi,

This is indeed a very interesting question and probably a widespread concern amongst educators from all background.

I think Emma shared some great tips and valuable insights. In addition to removing potential distractors, proposing tasks that trigger students’ interest and reasonably challenging students’ abilities, I think it is important to take into consideration the spacing effect. One of the most reliable finding in education is that learning is greater when studying is spread out over time, as opposed to studying the same content in a single session. Therefore, improving student’s length of concentration might, at least partly, require to allow them to space or distribute learning sessions over the day, over the week, and so on.

– Spacing effect is observed in various educational settings, groups and materials.
– When lessons are spaced, students learn more and forget less.
– Spaced practice works regardless of who controls the schedule.
– Spacing lessons seem to contribute to maintain activity in brain regions associated with successful encoding, working memory, etc.

An interesting instructional implication is suggested by Gerbier & Toppino (2015), « Instructors frequently summarize at the end of a class session the material that was covered that day. That is a good practice. However, it might be beneficial to summarize the previous day׳s lessons at the beginning of the next class, repeating information after a long enough spacing interval that the information has undergone a significant amount of consolidation. »

However, it is still unclear what is the optimal gap. Increasing the gap between study sessions can enhance retention, yet little is known about how distributed practice effect unfolds over nontrivial periods (Cepeda et al., 2009). Some algorithms are being developed experimentally and are worth a look (Lindsey et al., 2014).
