Experimental evaluation of classroom environments: scheduling planned activities

L W Frederiksen, C B Frederiksen

    American Journal of Mental Deficiency
    |March 1, 1977
    PubMed
    Summary

    Randomly scheduled classroom activities disrupted learning for adolescents with moderate intellectual disabilities (TMR). Predictable schedules improved task completion and reduced disruptions, highlighting the importance of routine for TMR students.

    Area of Science:

    • Special Education
    • Developmental Psychology
    • Behavioral Analysis

    Background:

    • Classroom activity scheduling impacts learning for adolescents with moderate intellectual disabilities (TMR).
    • Understanding the effects of predictable versus unpredictable routines is crucial for educational interventions.

    Purpose of the Study:

    • To investigate the impact of fixed (predictable) versus random (unpredictable) activity scheduling on TMR adolescents.
    • To analyze activity completion rates and disruptive behaviors under different scheduling conditions.

    Main Methods:

    • An ABAB design was employed to compare fixed and random scheduling of ten classroom activities.
    • Data collected included activity completion rates and frequency of disruptions.
    • Generalization of effects to unmanipulated activities was assessed.

    Main Results:

    • Random scheduling significantly decreased activity completion and increased disruptions compared to fixed scheduling.
    • Lower task completion and higher disruptions under random scheduling generalized to unmanipulated activities.
    • Individual student performance varied, with those initially struggling showing the greatest decrements under random scheduling.

    Conclusions:

    • Fixed, predictable classroom activity schedules are more effective for TMR adolescents.
    • Unpredictable scheduling negatively impacts academic engagement and behavior, underscoring the need for routine.
    • Educational strategies should prioritize consistent structures to support learning and reduce behavioral challenges.
