We have great news! The director, Dr. Min Ky Kim, has received the new NSF IUSE grant entitled 'Artificial Intelligence-Scaffolded Pre-Classroom Learning for Large, Introductory Undergraduate Physics Courses.' Dr. M. Shameer Abdeen from the Department of Physics & Astronomy at Georgia State University is the Co-PI of the grant project. See the information below.

NSF: Improving Undergraduate STEM Education (Grant/Award Number: 2315709)

  • Title: IUSE-Engaged Student Learning (Level 1): AI-Scaffolded Pre-Classroom Learning for Large/Introductory Undergraduate Physics Courses
  • Position: Principal Investigator 
  • Project dates: 08/01/2023 – 07/31/2026 
  • Budget: $ 298,375

This Engaged Student Learning Level 1 project aims to serve the national interest by designing and implementing an Artificial Intelligence (AI)-augmented formative assessment and feedback system. This system will help students develop source-based STEM arguments, such as STEM text summarization, or problem spaces, which are mental representations of a problem and of multiple paths to solving it. This will be implemented in large, undergraduate introductory physics courses at an urban university that serves diverse and historically underrepresented student groups. Persistent learner engagement in pre-classroom learning activities is critical to learner success in introductory STEM courses. Undergraduate students often need to develop a solid understanding of content or problem situations in self-paced online learning contexts to prepare for in-classroom active and collaborative learning. However, unsupervised pre-classroom learning can be an ongoing issue in a student-centered learning model. This problematic situation is particularly evident in large introductory-level STEM courses where traditional instructional techniques are less effective. The innovation of the project will include AI-generated adaptive scaffolding information and learning progress feedback with data visualization techniques to help students with concept learning and self-regulatory behaviors. The unique learning opportunities supported by an AI-scaffolded feedback system will significantly increase students' engagement levels in self-paced online pre-classroom learning. This, in turn, will help students acquire content knowledge and build a proper understanding of problems to prepare themselves for success in in-classroom interactive problem-solving activities.

This project will take three phases to develop and investigate the effectiveness of AI-augmented pre-classroom activities to promote engaging student experiences in undergraduate physics courses. The project's research will take a Participatory Research (PR) approach that emphasizes the direct engagement of faculty members who teach physics courses in designing and implementing new assignments. These faculty members will also co-construct research through a partnership with researchers to conduct a mixed-methods study of instructors and students in the courses. The primary research goal of the first phase is to identify topics and problem tasks that utilize AI-scaffolded pre-classroom learning and investigate learner engagement and progression in the pre-class assignments. The evaluation studies during the second phase will prove whether knowledge development during pre-classroom learning can help students solve cognitively demanding tasks in classrooms and develop positive self-efficacy in STEM. The findings will also determine whether AI in education improves students' well-being inside and outside of classrooms, with a focus on students traditionally underrepresented in STEM education. Extensive data collected in the final phase will uncover the relationships among pre-classroom activities, in-classroom performance, self-efficacy, interest in physics, and student backgrounds, including gender, race, ethnicity, first-generation status, and L2 learners. Our sequence mining and cluster analysis will reveal students' different hidden engagement states and group their engagement trajectories, explaining how cluster membership and trajectories vary across students' backgrounds. Consequently, this project will lay the groundwork for further research to develop an AI-scaffolded pre-classroom learning model that promotes most students' success in introductory physics courses. Through the Engaged Student Learning track, the program supports the creation, exploration, and implementation of promising practices and tools.

A Test of Learning Progress Models Using an AI-Enabled Knowledge Representation System
Monday, June 12th, 3:00 to 4:30 PM EDT, S-LAAI2 - AI and Human Interaction in Learning Environments 

This study tested two competing learning progress models - the three-stage and two-stage models - based on an AI-enabled formative assessment tool. Additionally, human-rated scores were used to further validate the models. The data for this investigation consisted of expository essays about a complex problem scenario written by 116 students and 6 experts. The validation analyses, including descriptive statistics, C-LCDM, and group-mean difference tests, demonstrated that the two-stage model was a better framework given the technology. The findings showed the potential of the model to determine learners' conceptual change over time.

 

An Investigation of Knowledge-Based AI vs. Human Evaluation in the Context of Academic Summary Evaluation: Similarities, Dissimilarities, and Being Toward Mutual Understandings
Monday, June 12th, 3:00 to 4:30 PM EDT, S-LAAI2 - AI and Human Interaction in Learning Environments 

This study aims to explore the similarities and dissimilarities of knowledge-based AI evaluations vs. human evaluations and discuss how they can be utilized for formative feedback in academic summary writing. Data were collected from 62 students who utilized AI-based formative feedback to make revisions to their summaries. We compared indices on three dimensions (surface, structure, semantic) that were automatically generated through this software with human-rated evaluations. MANOVA results of learners’ initial draft and final revision showed learning gains in the semantic dimension and human-evaluated scores. Some significant correlations were observed between automatic and human-rated evaluations. Given that each measure can be interpreted to provide different insights, we suggest combining knowledge-based AI and human evaluations for rich and informative feedback.

 

Clustering Cognitive Engagement Changes in Longitudinally Traced Discussion Data from a Graduate-Level Online Course
Thursday, June 15th, 10:30 to 12:00 PM EDT, CSCL-S10 / Important considerations for STEM collaboration in Higher Education 

Given the pervasive use of online learning, especially asynchronous discussion forums, ensuring students’ ongoing engagement is critical. Examining students’ cognitive presence throughout a series of discussions can disclose different engagement patterns. However, little research has leveraged longitudinal discussion data. The current study aims to identify learner engagement states and their trajectories in discussion forums using two-cohort data from a graduate-level online course. We used HMM (Hidden Markov model) to discover the hidden longitudinal engagement clusters. Results showed two clusters in the first cohort and three clusters in the second cohort. Students tended to remain in a similar engagement state, and their participation patterns depended on the discussion dynamics likely influenced by class size.

Members of our AI2 Lab attended and presented at the 2023 American Educational Research Association (AERA) Annual Meeting, which took place from April 13-16 at Chicago, IL.

Dr. Min Kyu Kim and our graduate associate, Jinho Kim, presented the paper titled "Using Machine Learning for Cognitive Presence Detection in Asynchronous Online Learning" at the Instructional Technology SIG Roundtables on the 13th.

Title: 

Using Machine Learning for Cognitive Presence Detection in Asynchronous Online Learning

Abstract:

This study aims to explore and develop a machine learning model to automatically detect individual students’ levels of cognitive presence they exert while participating in online discussions. To this end, we used the Practical Inquiry Model to analyze 1,360 discussion posts gathered from the multiple sections of a graduate-level online course. We have used the training data to develop a machine learning model. Especially, we tested a deep learning algorithm, Bidirectional Encoder Representations from Transformers (BERT) model, to find the most suitable hyperparameters. Our final model showed a 94% accuracy in detecting cognitive presence levels reflected on given discussion posts. Findings demonstrate the potential of AI to detect students’ cognitive presence and provide real-time feedback.
