Implementing Learning Principles with a Personal AI Tutor: A Case Study
Effective learning strategies based on principles like personalization,
retrieval practice, and spaced repetition are often challenging to implement
due to practical constraints. Here we explore the integration of AI tutors to
complement learning programs in accordance with learning sciences. A
semester-long study was conducted at UniDistance Suisse, where an AI tutor app
was provided to psychology students taking a neuroscience course (N=51). After
automatically generating microlearning questions from existing course materials
using GPT-3, the AI tutor developed a dynamic neural-network model of each
student's grasp of key concepts. This enabled the implementation of distributed
retrieval practice, personalized to each student's individual level and
abilities. The results indicate that students who actively engaged with the AI
tutor achieved significantly higher grades. Moreover, active engagement led to
an average improvement of up to 15 percentile points compared to a parallel
course without AI tutor. Additionally, the grasp strongly correlated with the
exam grade, thus validating the relevance of neural-network predictions. This
research demonstrates the ability of personal AI tutors to model human learning
processes and effectively enhance academic performance. By integrating AI
tutors into their programs, educators can offer students personalized learning
experiences grounded in the principles of learning sciences, thereby addressing
the challenges associated with implementing effective learning strategies.
These findings contribute to the growing body of knowledge on the
transformative potential of AI in education.Comment: 17 pages, 7 figure

Éléments de validité à propos d’un instrument mesurant le climat relationnel perçu par des étudiants et étudiantes universitaires à distance
Le questionnaire Climat relationnel des Ă©tudes Ă l’UniversitĂ© (CREU) (Genoud, 2008) a Ă©tĂ© adaptĂ© en français et en allemand et intitulĂ© Climat relationnel des Ă©tudes Ă distance (CRED). Une analyse factorielle confirmatoire (n = 223) soutient la structure du CRED en quatre sous-Ă©chelles. D’autres Ă©lĂ©ments de validitĂ© sont fournis par des coefficients de cohĂ©rence interne et par la comparaison avec les rĂ©sultats antĂ©rieurs obtenus par Genoud (2008). Toutefois, une faible invariance de mesure entre les Ă©chantillons (francophones et germanophones) et des indices d’ajustement parfois insuffisants, en particulier pour la version allemande, invitent Ă la nuance. La validitĂ© de critère est Ă©tayĂ©e par des liens significatifs positifs entre le sentiment d’auto-efficacitĂ©, la persĂ©vĂ©rance et la qualitĂ© perçue du climat relationnel (CRED). Des liens nĂ©gatifs ont Ă©tĂ© trouvĂ©s entre le CRED et la propension Ă l’ennui (SBPS). Aucun lien n’apparait entre le climat relationnel et les performances (notes).To provide a tool to measure classroom climate in the specific context of distance learning, the Relational Climate of University Study (CREU ; Genoud, 2008) questionnaire was adapted in French and German. We named it the Relational Climate of Distance Learning (CRED). The four-scale structure of the CRED (and of the CREU) was confirmed by confirmatory factor analysis (n=223) and internal consistency analyses. These elements of validity are compared with the previous results obtained by Genoud (2008). However, a weak measurement invariance between the samples (French and German) and sometimes insufficient fit indices, in particular for the German version, call for nuance. Investigation of the psychometric qualities of the CRED was supplemented by criterion validity tests. Consistent with previous work, significant positive medium-sized relationships were found between perceived quality of classroom relational climate (CRED), feelings of self-efficacy, and persistence. No relationship was found with academic performance (i.e. grades).O questionário Clima relacional de estudos universitários (CREU ; Genoud, 2008) foi adaptado para francĂŞs e alemĂŁo e intitulado Clima relacional de estudos Ă distância (CRED). Uma análise fatorial confirmatĂłria (n=223) apoia a estrutura do CRED em quatro subescalas. Outros elementos de validade sĂŁo fornecidos pelos coeficientes de consistĂŞncia interna e pela comparação com resultados anteriores obtidos por Genoud (2008). No entanto, uma baixa invariância de medição entre as amostras (francĂłfona e alemĂŁ) e Ăndices de ajustamento por vezes insuficientes, em particular para a versĂŁo alemĂŁ, convidam a ter em atenção as diferenças mais subtis. A validade do critĂ©rio Ă© apoiada por relações significativas positivas entre o sentimento de autoeficácia, a perseverança e a qualidade percebida do clima relacional (CRED). Foram encontradas relações negativas entre o CRED e a propensĂŁo ao tĂ©dio (SBPS). NĂŁo aparece nenhuma relação entre o clima relacional e os desempenhos (notas)
