Courses in Learning Analytics

Instructor: Dr. Son T. H. Pham Nha Viet Institute, Massachusetts

Course Overview: This comprehensive course is designed for educators, administrators, policy makers, and education practitioners seeking to harness data-driven insights to improve educational outcomes. The curriculum covers foundational to advanced topics in learning analytics, emphasizing practical applications and ethical considerations in education.

Core Topics:

  1. Data Wrangling & Exploratory Analysis: Introduction to data preparation, visualization, and basic modeling using tools such as R, Python, GitHub, APIs, and modern data-intensive research workflows.

  2. Supervised Learning: Techniques including feature engineering, model tuning, and evaluation metrics for predictive modeling.

  3. Unsupervised Methods: Clustering, factor analysis, and knowledge structure exploration to identify hidden patterns.

  4. Relationship Mining: Methods for correlation analysis, association and sequential rule mining, and evaluation of association metrics.

  5. Knowledge Tracing: Study of student learning models including Bayesian Knowledge Tracing (BKT), Performance Factor Analysis (PFA/LKT), and Deep Knowledge Tracing (DKT).

  6. Social Network Analysis: Measurement of network properties, identification of key actors and groups, and network modeling approaches.

  7. Text Mining: Techniques such as topic modeling, text classification, and epistemic network analysis for educational text data.

  8. Emerging Technologies: Exploration of large language models (LLMs) and knowledge graphs in educational contexts.

Key Features:
  • Strong focus on reproducible research and open science principles.

  • Critical examination of ethical and legal issues, including student privacy, data ethics, and algorithmic bias.

  • Application-driven insights for STEM education, covering intelligent tutoring systems, adaptive learning environments, curriculum design, and early identification of at-risk students.

  • Preparation for collaborative work through research-practice partnerships with educational organizations at local, district, and state levels.

Whether you’re new to learning analytics or looking to deepen your expertise, our curriculum can be customized to align with your specific goals and context.

Short Answer… Yes, to an extent.

Each point in the scatterplot indicates the amount of time a student spent logged into their online course and their final grade. For each of five online STEM courses offered by the statewide virtual public school from which this data was collected, there is a positive relationship between the amount of time students spent and their course grade. However, there also appears to be diminishing returns of course grade after roughly 40 hours, where invested time does not necessarily correspond to higher course grades.

The boxplot and histogram in the two smaller boxes show distributions of hours logged in online and final grades for all course offerings in each subject area. On average, students spent the most time on Anatomy (40.1 hours) and the least time on Biology (21.2 hours); students earned the highest grades in Physics (83.7%) and the lowest grades in Biology (65.6%). The Biology course may need some attention as students on average earned the lowest grades and spent the least amount of time on the course.

Fine print: Time spent online does not necessarily account for all time students spent on the course, e.g, studying offline.
