This document summarizes a study that examined the effects of adapting homework instructions to match the characteristics of Dutch HAVO 4 students. The study found:
1) Adapting homework instructions to fit students' characteristics significantly increased students' homework motivation, primarily by increasing their expectancy of success.
2) Effects varied by subject, with mathematics and economics students reporting significantly higher motivation, while history and chemistry students showed no significant changes.
3) Pre-existing differences in students' planning skills and relationships with teachers significantly impacted their homework expectancy levels. Students with below-average scores on these characteristics had lower expectancy.
The results suggest adapting homework instructions based on student characteristics can increase motivation and that teachers should differentiate instructions
