The Moderating Role of Intelligence and Prior Knowledge for the Effectiveness of a Computer-Based Mathematics...

Area of Science:

• Educational Psychology
• Cognitive Science
• Learning Sciences

Background:

• Understanding how individual differences like intelligence and prior knowledge influence intervention effectiveness is crucial for tailored educational strategies.
• Investigating these moderators helps optimize the design and implementation of learning interventions for diverse student populations.

Purpose of the Study:

• To analyze the moderating effects of intelligence and prior knowledge on a computer-based mathematics intervention's effectiveness.
• To examine individual learning trajectories within a sample of primary school students with low mathematics performance and low-to-average intelligence.

Main Methods:

• Employed an ABAB-single-case research design with 10 primary school students.
• Assessed prior knowledge and intelligence before the intervention.
• Utilized hierarchical piecewise regression analysis to examine moderation effects.

Main Results:

• A significant negative moderation of intervention effectiveness by intelligence was observed.
• Students with higher intelligence exhibited slower learning rates in this specific low-performing sample.
• Prior knowledge did not demonstrate a significant moderating influence on intervention outcomes.

Conclusions:

• The computer-based mathematics intervention's effectiveness was negatively moderated by student intelligence.
• Higher intelligence may lead to slower learning in interventions targeting basic numerical skills for low-performing students.
• The intervention's focus on basic skills might have been less effective for more intelligent students who may have already mastered them.
