The way EdTechs currently use 𝗦𝗽𝗮𝗰𝗲𝗱 𝗥𝗲𝗽𝗲𝘁𝗶𝘁𝗶𝗼𝗻 often leads to "𝗳𝗮𝗸𝗲 𝗹𝗲𝗮𝗿𝗻𝗶𝗻𝗴"... When start ups claim their product is backed by learning science, Spaced Repetition usually is one of the go-to techniques. The idea is simple: When we hear new information we typically have forgotten roughly - 40% after 20min - 55% after 1h - 75% after 1 week To counter that, we simply repeat the input in certain intervals. Thereby we retain more information for longer periods. It works. No doubt about that. There is scientific evidence. 𝗦𝗼 𝘄𝗵𝗲𝗿𝗲 𝗶𝘀 𝘁𝗵𝗲 𝗰𝗮𝘁𝗰𝗵? In my opinion the technique is based on an insufficient concept of what learning is about. Bold thesis, I know, but here is why: Think about the result we are optimising for with this... It’s just about memorising pieces of information. Be it historical facts, vocabulary or the structure of a project management method. De facto the process is seen as “successful” when the learner is able to repeat a certain set of words. ▶ 𝘛𝘩𝘦 𝘤𝘰𝘯𝘴𝘦𝘲𝘶𝘦𝘯𝘤𝘦: 𝘛𝘩𝘦 𝘪𝘥𝘦𝘢 𝘰𝘧 𝘭𝘦𝘢𝘳𝘯𝘪𝘯𝘨 𝘪𝘴 𝘳𝘦𝘥𝘶𝘤𝘦𝘥 𝘵𝘰 𝘮𝘦𝘳𝘦𝘭𝘺 𝘮𝘦𝘮𝘰𝘳𝘪𝘴𝘪𝘯𝘨 𝘢𝘯𝘥 𝘳𝘦𝘱𝘳𝘰𝘥𝘶𝘤𝘪𝘯𝘨 𝘪𝘯𝘧𝘰𝘳𝘮𝘢𝘵𝘪𝘰𝘯. Citing isolated facts may look like learning on the outside. BUT, ▶ do learners develop a profound understanding of the subject in that way? ▶ are the learnings really actionable? ▶ and are they able to make inferences based on it? I would strongly argue against that. Hence, the term fake learning. We want learners not just to repeat words. We want them to develop "integrated knowledge", as it is called in learning psychology. That means that any new input is not just stored in longterm memory — but is linked cognitively with existing information and experiences related to the given topic. Only then, knowledge ▶ becomes available when it is relevant, ▶ can be transferred to different contexts ▶ and really affects the learners’ behaviour. If we pose that as our desired learning outcome, we will quickly find that spaced repetition in itself is insufficient. 𝗦𝗼, 𝗵𝗼𝘄 𝗰𝗮𝗻 𝘄𝗲 𝘂𝘀𝗲 𝗦𝗽𝗮𝗰𝗲𝗱 𝗥𝗲𝗽𝗲𝘁𝗶𝘁𝗶𝗼𝗻, 𝘄𝗶𝘁𝗵𝗼𝘂𝘁 𝗺𝗮𝗸𝗶𝗻𝗴 𝗹𝗲𝗮𝗿𝗻𝗶𝗻𝗴 𝘀𝘂𝗽𝗲𝗿𝗳𝗶𝗰𝗶𝗮𝗹? ▶ Imo, We should not see Spaced Repetition as a an instructional technique in itself, but rather as a 𝗹𝗮𝘆𝗲𝗿 on top of our learning methodology: It only determines WHEN we confront a learner with a given topic, but not HOW deliver that input. Consequently, it is usually not mutually exclusive with other techniques — so it can (and should) be supplemented with them. Constructivist learning methods, e.g. reflect that perspective of integrated knowledge much better, so the combination of both can be really powerful (▶ observational learning, encoding support, socratic teaching…). In short: Let's think of Spaced Repetition as an organisational structure not as a standalone technique! Curious to hear what you think!

Absolutely. I'm so glad you mentioned constructivist methods as well! I'm a big fan of spaced recall/retrieval, not just repetition, but it's so important to layer in other forms of engagement with the relevant concepts at the same time: - What new questions (or even objections) do you have about this idea? - How does it relate to other things you've learned more recently? - How are you using this in practice, or how might you? - Who else might use this information, and how would you explain it to them? I'd love to know more about how you're incorporating these approaches into EdTech tools or systems - thanks for the post!

Philipp Behr very interesting prerspective. Integrated knowledge as a structure could be next generation lifelong learning or like LIFESTYLE learning. Lets think together 😊
