This dissertation introduces two frameworks: the Cross-Institutional Stacking Ensemble (CISE) predictive model and ReflectMate, a reflective learning analytics tool. Together, they address challenges in ICT education, such as dataset heterogeneity, class imbalance, and disparities caused by the digital divide, transforming educational practices through predictive analytics and reflective learning.<\/div>\n<div><\/div>\n<div>The <em>CISE model<\/em> is an ensemble learning framework that forecasts student academic performance across diverse institutional contexts. It integrates five machine learning classifiers\u2014Decision Tree, Random Forest, Naive Bayes, Neural Network, and Support Vector Machine\u2014synthesized via a logistic regression-based meta-model. Achieving an <em>F1 score of 78.25%<\/em> on the ENSIM validation dataset, CISE demonstrates superior accuracy and generalizability in identifying at-risk students.<\/div>\n<div><\/div>\n<div>Complementing CISE, <em>ReflectMate<\/em> empowers students with real-time insights into their learning behaviors (e.g., quiz attempts, assignment submissions, LMS interactions). Through progress tracking, tailored feedback, and interactive dashboards, ReflectMate fosters self-reflection, self-regulation, and accountability. Surveys conducted among CADT students confirm its effectiveness in promoting metacognition and academic engagement.<\/div>\n<div><\/div>\n<div>This research also addresses <em>digital equity<\/em>, revealing gender and location-based disparities in ICT education. By combining predictive modeling with reflective learning tools, this work contributes scalable, student-centered solutions to bridge systemic gaps and promote inclusive academic success.<\/div>\n<div><\/div>\n<div><\/div>\n<div class=\"elementToProof\"><b>Keywords : <\/b>Student performance prediction, learning analytics, predictive modeling, reflective learning, cross-institutional validation, student engagement.<\/div>\n<div><\/div>\n<div><\/div>\n<\/div>\n<p style=\"text-align: justify;\" align=\"justify\"><img decoding=\"async\" loading=\"lazy\" class=\"alignnone size-large wp-image-26525\" src=\"http:\/\/lium.univ-lemans.fr\/wp-content\/uploads\/2025\/05\/These_Dynil_21-05-2025_2-min-1024x768.jpg\" alt=\"\" width=\"1024\" height=\"768\" srcset=\"https:\/\/lium.univ-lemans.fr\/wp-content\/uploads\/2025\/05\/These_Dynil_21-05-2025_2-min-1024x768.jpg 1024w, https:\/\/lium.univ-lemans.fr\/wp-content\/uploads\/2025\/05\/These_Dynil_21-05-2025_2-min-300x225.jpg 300w, https:\/\/lium.univ-lemans.fr\/wp-content\/uploads\/2025\/05\/These_Dynil_21-05-2025_2-min-768x576.jpg 768w, https:\/\/lium.univ-lemans.fr\/wp-content\/uploads\/2025\/05\/These_Dynil_21-05-2025_2-min-1536x1152.jpg 1536w, https:\/\/lium.univ-lemans.fr\/wp-content\/uploads\/2025\/05\/These_Dynil_21-05-2025_2-min-2048x1536.jpg 2048w, https:\/\/lium.univ-lemans.fr\/wp-content\/uploads\/2025\/05\/These_Dynil_21-05-2025_2-min-380x285.jpg 380w, https:\/\/lium.univ-lemans.fr\/wp-content\/uploads\/2025\/05\/These_Dynil_21-05-2025_2-min-285x214.jpg 285w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/p><\/div><\/div><\/div><\/div>","protected":false},"excerpt":{"rendered":"<p>PhD defence, Dynil DUCH Date : 21\/05\/2025 Time : 9h00 Location : Institut d&#8217;Informatique Claude Chappe, Amphitheatre Hall Phd defence video : &nbsp; Title &#8211; Predicting Student Performance through Cross-Institutional Learning Analytics: CISE Model and Reflective Learning Tools \u00a0 Jury composition : M.
