The relative effects on math performance of single- versus multiple-ratio schedules: a case study

Area of Science:

• Behavioral Psychology
• Educational Psychology
• Learning Sciences

Background:

• Understanding factors influencing student engagement with academic materials is crucial.
• Reinforcement schedules are known to impact learning behaviors.
• Previous research has explored various reinforcement strategies.

Purpose of the Study:

• To compare the effectiveness of multiple-ratio versus single-ratio reinforcement schedules.
• To assess the impact of these schedules on a student's response rate to mathematics.
• To investigate the influence of reinforcement frequency as a secondary factor.

Main Methods:

• Conducted a series of four experiments involving a pupil and mathematics materials.
• Manipulated reinforcement schedules, alternating between single- and multiple-ratio contingencies.
• Varied reinforcement frequency in one experiment to assess its independent effect.

Main Results:

• Multiple-ratio schedules led to higher response rates compared to single-ratio schedules.
• Experiment I and II demonstrated a clear increase in response rates under multiple-ratio conditions.
• Experiment III indicated that altering reinforcement frequency had a minimal effect on response rates.

Conclusions:

• Multiple-ratio reinforcement schedules are more effective in increasing student response rates to academic tasks.
• Reinforcement frequency appears to be a less influential variable than the schedule type.
• Findings support the use of multiple-ratio schedules in educational settings to enhance engagement.
