AI-generated Key Points
- The flipped classroom is a popular pedagogical approach
- It involves watching video-recorded lectures at home and group-based problem-solving discussions in class
- Spoken discussion dialogues are common and provide valuable information about learning processes and outcomes
- Learning analytics can be used to collect and analyze spoken discussion dialogues
- Researchers recorded in-class group discussions, manually transcribed them, and extracted features using multiple tools and customized processing techniques
- Statistical analyses were performed to explore indicators related to group learning outcomes from face-to-face discussion dialogues in the flipped classroom
- Machine learning algorithms were applied to these indicators to predict group learning outcomes as High, Mid, or Low with 78.9% accuracy
- Analyzing spoken discussion dialogues can help educators understand how groups learn and identify areas for improvement
- This approach could potentially be scaled up for use across different classrooms and educational settings
Abstract: The flipped classroom is a new pedagogical strategy that has been gaining increasing importance recently. Spoken discussion dialog commonly occurs in flipped classroom, which embeds rich information indicating processes and progression of students' learning. This study focuses on learning analytics from spoken discussion dialog in the flipped classroom, which aims to collect and analyze the discussion dialogs in flipped classroom in order to get to know group learning processes and outcomes. We have recently transformed a course using the flipped classroom strategy, where students watched video-recorded lectures at home prior to group-based problem-solving discussions in class. The in-class group discussions were recorded throughout the semester and then transcribed manually. After features are extracted from the dialogs by multiple tools and customized processing techniques, we performed statistical analyses to explore the indicators that are related to the group learning outcomes from face-to-face discussion dialogs in the flipped classroom. Then, machine learning algorithms are applied to the indicators in order to predict the group learning outcome as High, Mid or Low. The best prediction accuracy reaches 78.9%, which demonstrates the feasibility of achieving automatic learning outcome prediction from group discussion dialog in flipped classroom.
