Classwide Fraction Intervention for 4th Graders with Math Learning Difficulties

This study, called "Implementing Inclusive Fraction Intervention Classwide," is looking at how a special teaching method called Classwide Fraction Intervention (CFI) affects the understanding of fractions in fourth-grade students. CFI is a behavioral intervention, meaning it's a way of teaching, not a medicine. It involves 40 sessions, twice a week for about 25-31 minutes each, focusing on understanding fraction size and how to do calculations with fractions. The study aims to see if CFI helps students with and without math learning difficulties. You might be eligible if you are a 8-11 year old student in a participating Metropolitan-Nashville Public School. Success in this study means students show improvement in their ability to order fractions, estimate fractions on a number line, and perform fraction calculations. The study is currently unclear on its recruitment status and plans to enroll 2210 students.

Study design
This interventional study involves teachers being randomly assigned to either use the Classwide Fraction Intervention (CFI) in their classroom or continue with their standard math program. It aims to enroll 2210 students.
What's involved
If you participate, your child will complete tests before and after the intervention. Teachers will also report scores from school-collected measures and be observed during CFI implementation.
Compensation
Not stated in the trial record.
Follow-up
Students are tested within three weeks before the intervention starts and within three weeks after it ends.

Eligibility criteria

Inclusion

To enter the study, students must meet the following criteria. They must attend a Metropolitan-Nashville Public School whose principal has given permission for his/her school to participate and participate in a fourth-grade classroom whose teacher has agreed to let her/his students participate.

Exclusion

We exclude students with identified intellectual disability from study data collection because CFI is not designed to meet the needs of this population. There are no other exclusions.

What this trial measures

  • Change in Fraction Ordering ScorePre-intervention measurement will take place within three weeks prior to beginning of intervention; post-intervention measurement will take place within three weeks after completion of intervention.

    In Fraction Ordering, students order 11 strings of 3 fractions to be ordered from least to greatest. The student's score is the change from pre-intervention to post-intervention in the number of correctly ordered strings.

  • Change in Fraction Number Line Estimation ScorePre-intervention measurement will take place within three weeks prior to beginning of intervention; post-intervention measurement will take place within three weeks after completion of intervention.

    In Fraction Number Line Estimation, students place fractions on a 0-2 number line, presented via computer with labeled endpoints. Accuracy for each of the 20 items is the absolute value of the difference between actual and correct answer multiplied by 100. The student's score is the change from pre-intervention to post-intervention in average accuracy across all 20 items.

  • Change in Fraction Calculations ScorePre-intervention measurement will take place within three weeks prior to beginning of intervention; post-intervention measurement will take place within three weeks after completion of intervention.

    In Fractions Calculations, students complete 25 fraction calculation problems with like and unlike denominators, with and without whole or mixed numbers. The student's score is the change from pre-intervention to post-intervention in the number of correct answers.
