ECR Betty’s Brain-BROMP

Modeling Self Regulated Learning with Betty’s Brain

Overview:

The primary goal for this project is to enhance the theory and measurement of students’ self-regulated learning (SRL) processes during science learning by developing a technology based framework which leverages human expert judgment and machine learning methods to identify key moments during SRL and analyze these moments in depth.

These issues are being studied in the context of Betty’s Brain, an open-ended science learning environment that combines learning-by-modeling with critical thinking and problem-solving skills to teach complex science topics.

We are developing a novel measurement framework that will identify key inflection points in learners’ SRL processes that drive their cognition, metacognition and affect, and inform researchers about these inflection points in real time, so that the researchers can conduct observations and interviews right at the critical moments when the change is occurring. The results of this data collection will be integrated with sequential pattern mining to drive the refinement and extension of an existing theory of SRL (Winne’s COPES framework) to increase its specificity and predictive power.

 

Funding agency:

 

Status:

  • Building and refining of automated detectors for affect, cognition, metacognition, and SRL behaviors (feature engineering and deep learning approaches)
  • Design of Study 2, including –
  1. development of a new android app that will notify classroom researchers of key inflection points in the cognitive, metacognitive, and SRL behaviors of students as detected in real time
  2. Development of the app-server-clients communication framework
  3. Pilot study (May 2018 – Jere Baxter Middle School, Nashville, TN) to test this newly developed framework in a classroom setting)
