Many factors are involved in studying the effectiveness of different types of homework. Research studies suggest that the following guidelines are most effective:
- Homework assignments meant to practice past lessons or prepare for future lessons–or both–can be more effective than assignments that include only same-day content.
- Dispersing easy and hard material throughout the assignment has a positive effect on measures of homework accuracy and completion rates.
- Homework assignments based on students’ individual learning style may improve students’ achievement.
- Some form of feedback on homework assignments benefits students.
- Rewards for homework completion can increase completion rates for students with learning disabilities or low motivation.
There is some evidence that shorter homework assignments are more effective than longer assignments and that group assignments can be effective. These findings tend to depend on the grade level of the students.
