An AI study coach is a software system that uses artificial intelligence to personalise your learning. Unlike a generic chatbot (ChatGPT, Gemini), a real AI study coach:
The research is clear: intelligent tutoring systems (ITS) — the academic term for AI study coaches — produce learning outcomes nearly as large as human one-on-one tutoring. The landmark finding is from VanLehn (2011), who demonstrated that computer-based tutoring achieves an effect size of d = 0.76, compared to d = 0.79 for human tutoring.
Every tool in Revaldo AI is built on one or more proven learning principles. Here are the studies that define what an effective AI study coach should do:
1 AI tutoring produces learning gains nearly equal to human 1-on-1 tutoring (d = 0.76 vs d = 0.79)
VanLehn (2011) — “The relative effectiveness of human tutoring, intelligent tutoring systems, and other tutoring systems.” Educational Psychologist, 46(4), 197–221.
2 Practice testing is the highest-utility learning technique. Quizzing yourself beats re-reading, highlighting, and summarising.
Dunlosky, Rawson, Marsh et al. (2013) — “Improving students’ learning with effective learning techniques.” Psychological Science in the Public Interest, 14(1), 4–58.
3 Retrieval practice boosted retention to 80% vs 36% for re-reading after one week
Roediger & Karpicke (2006) — “Test-enhanced learning.” Psychological Science, 17(3), 249–255.
4 70% of information is forgotten within 24 hours without spaced review (the forgetting curve)
Ebbinghaus (1885/1913) — Memory: A Contribution to Experimental Psychology. Teachers College, Columbia University.
5 Distributed practice is the most reliable finding in educational psychology. Spacing beats cramming.
Cepeda, Pashler, Vul et al. (2006) — “Distributed practice in verbal recall tasks.” Psychological Bulletin, 132(3), 354–380.
6 Students who self-explained solved 3x more problems than those who didn’t
Chi, Bassok, Lewis et al. (1989) — “Self-explanations: How students study and use examples.” Cognitive Science, 13(2), 145–182.
7 Interactive learning produces the deepest understanding (Interactive > Constructive > Active > Passive)
Chi & Wylie (2014) — “The ICAP framework.” Educational Psychologist, 49(4), 219–243.
8 Feedback is one of the top 10 influences on learning across 800+ meta-analyses
Hattie (2009) — Visible Learning: A synthesis of over 800 meta-analyses relating to achievement. Routledge.
9 Combining spacing, interleaving, and testing creates “desirable difficulties” that maximise long-term retention
Bjork & Bjork (2011) — “Making things hard on yourself, but in a good way.” Psychology and the Real World, 56–64.
10 Implementation intentions (specific study plans) double or triple goal completion
Gollwitzer & Sheeran (2006) — “Implementation intentions and goal achievement.” Advances in Experimental Social Psychology, 38, 69–119.
