Sentiment, Emotion, and Engagement Outcomes When Students Skip Mastered Content: A 6-Week Crossover in Grades 3–6

nonstatic.education Research · Applied-Research Draft

Abstract

Compares student engagement, affect, and free-response sentiment when learners are permitted to skip lessons in subjects they have already demonstrated mastery of, versus proceeding through full sequencing. Twenty students complete an AB/BA crossover. Measures weekly affect (PANAS-C + Smileyometer), behavioral engagement (time-on-task, voluntary practice, lesson-completion rate), and NLP-based semantic and sentiment analysis of weekly student journal entries; analyzed via mixed-effects models.

Research Question

When students who have demonstrably mastered a topic are allowed to skip its associated lessons, does their reported affect, engagement behavior, and free-text sentiment improve — and if so, does this benefit persist across subjects where mastery has not yet been achieved?

Study Design

  • AB/BA crossover: students alternate between skip-enabled weeks (Condition A) and full-sequencing weeks (Condition B)
  • ~20 students enrolled across Grades 3–6 at a single site in Multan, Pakistan
  • Mastery thresholds established per subject via the AI LMS prior to study commencement
  • Within-subject design controls for baseline differences in engagement and sentiment
  • Weekly journal entries collected and analyzed using NLP-based sentiment classification

Measures

  • Affect (primary): PANAS-C + Smileyometer — administered at end of each school week
  • Behavioral engagement: Time-on-task, voluntary practice sessions, lesson-completion rate — pulled from LMS logs
  • Sentiment (qualitative): NLP-based semantic and sentiment classification of open-ended weekly student journal entries
  • Analysis: Linear mixed-effects models; sentiment scores treated as a secondary outcome alongside NLP category frequencies

Expected Contribution

The assumption in most school systems is that students must complete all assigned content regardless of demonstrated mastery. This study tests whether that assumption carries an emotional cost — and whether skip-enabling produces measurable improvements in affect and intrinsic engagement that would support more agile, self-paced curriculum design.
