Current Projects

An Interactive Electronic Textbook for Python Programming and Data Science Courses

Peter Brusilovsky proposes to develop AdaPT, an interactive and adaptive system for learning and practicing Python programming and Data Science skills, which fuses a well-tested electronic textbook with a large volume of “smart” interactive learning content: worked code examples, code animations, and several types of automatically assessed practice problems. The system uses advanced learner modeling to trace the growth of learner’s knowledge and skills and to identify misunderstood concepts. Adapting dynamically to the current state of knowledge, it suggests most appropriate interactive content to practice at every step of learning.

Investigating and Evaluating Exploratory Recommender Systems

Exploratory recommender systems bring together the power of Human and Artificial Intelligence through human-AI collaboration and user-controlled recommendation. In this project, we develop and evaluate exploratory recommender systems in several domains. The focus of the project are carousel-based interfaces and novel recommender algorithms that can better adapt to user actions in the human-AI collaboration process.

An Infrastructure for Sustainable Innovation and Research in Computer Science Education

Researchers from the University of Pittsburgh, Carnegie Mellon University, North Carolina State University, and Virginia Tech collaborate to support the Computer Science Education Hub, social and technical infrastructure to accelerate research on teaching and learning of computing disciplines. The Hub will host community events and provide a web repository for computing education datasets, tools, and common analysis methods. The Hub facilitates creation and adoption of new tools to support computing educators and students, and new standards to support data collection and data-enabled research. Hub community events help researchers and educators from many learning contexts to develop and improve computing education resources.

Integrating Complementary Learning Principles in Aphasia Rehabilitation via Adaptive Modeling

Aphasia, commonly caused by stroke or other acquired brain injuries, can have a negative effect on an individual’s quality of life, often leading to depression and feelings of isolation. A primary frustration for people with aphasia is anomia, or word-finding difficulty. In this NIH-funded project, an interdisciplinary team of researchers will work on developing and evaluating novel adaptive computer-based aphasia treatments to help improve the efficiency and long-term impact of language treatment.

Supported by NIH grant 1R01DC019325-01A1 (2021 - 2026).

HELPeR - Health e-Librarian with Personalized Recommender

As the Internet has become a prominent source of health information to guide patients’ decision-making and self-management activities, patients strongly indicate they need navigational support to locate appropriate information on the Internet. The overall goal of this project is to build and implement a “Health E-Librarian with Personalized Recommendations (HELPeR)” - a personalized information access system with a hybrid recommender engine that adapts to different aspects of the patient: information needs based on the user’s profile, the user’s uniquely expressed information interests, and the level of user’s disease-related knowledge.

Supported by NIH grant R01-LM013038-02 (2019 - 2023).

The Pitt Grapevine: An Academic Recommender System

The goal of the project is to connect students with research advisors at the University of Pittsburgh through an interactive recommender system.

Supported by the University of Pittsburgh through the Personalized Education program (2018-2020). ==> more

Past Projects

Community-Building and Infrastructure Design for Data-Intensive Research in Computer Science Education

The mission of this collaborative project is to support the CS Education community by supplying documentation and infrastructure to help with adopting shared standards, protocols, and tools. In this way we hope to promote

• development and broader re-use of innovative learning content that is instrumented for rich data collection;
• formats and tools for analysis of learner data; and
• best practices to make large collections of learner data and associated analytics available to researchers in the CSE, data science, and learner science communities.

CSEdPad: Investigating and Scaffolding Students' Mental Models during Computer Programming Tasks to Improve Learning, Engagement, and Retention

This project is a joint effort of research teams at the University of Memphis and the University of Pittsburgh to explore the process of code comprehension by students and build AI-based tools to support the practice and assessment of code comprehension. In the course of the project, we developed and evaluated open-learned modeling approaches, code-tracing tools to practice code comprehension, and an intelligent tutor for assessing code comprehension through explanations.

Open Corpus Personalized Learning

This project challenges the assumption that adaptive hypermedia systems require expensive knowledge engineering for domain and content modeling. It replaces the carefully-crafted domain model with automatically-created domain models, lowering the cost of developing such systems while also providing a wider range of instructional paths through the content.
