The study took place in multiple classrooms and schools within a single school district over a 5-year period. Each year of the study, the study involved a new cohort of approximately 250 fourth-grade students from 50 classrooms in 14 elementary schools. The location of the schools was not specified.
Study students were fourth-grade students considered at-risk in mathematics, which the authors defined as scoring below the 35th percentile on a computation test. Among students who met the definition of at-risk within study classrooms, the authors sampled three to nine students per class for inclusion in the study. Averaging across the five student cohorts, approximately 52% of students were African American, 19% were White, 23% were Hispanic, and 6% were another race or ethnicity. Approximately 55% of students were female, 15% English learners, 88% were eligible for free or reduced-price lunch, and 10% were in special education classrooms.
Fraction Face-Off! is a supplemental math program designed to support fourth-grade students who need assistance solving fraction problems. Teachers use program materials with individual students or small groups to promote understanding of the magnitude of fractions, to compare two fractions, to put three fractions in order, and to place fractions on a number line. The program includes 36 lessons, each with four activities: a warm-up problem, group work, a speed game to build fluency, and a worksheet to check students’ understanding. These lessons are designed to be taught three times a week for 12 weeks. Within each study class, the Fraction Face-Off! intervention was delivered by one teacher to small groups (three-to-one ratio) three times per week for 12 weeks between September/October and early February. Each teacher was responsible for two to four groups. Depending on each regular classroom teacher’s scheduling preference, the teacher delivered the intervention to the study students through pull-out tutoring sessions that took place during one of the three school instructional periods: 1) students' math block (typically 50 minutes), 2) math center time (typically 20 minutes), or 3) the school's intervention period (typically 45 minutes). Study teachers were graduate students funded by the research grant; some were licensed teachers, but most were not licensed. Each of the 36 lessons varied in length between 30 and 35 minutes, and included four to six activities. In year 1, there was one intervention group, and each lesson included four activities: introduction of concepts or skills (8–12 minutes), group work (8–12 minutes), the speed game (1 minute), and individual work (8 minutes). In years 2 through 5, when there were two Fraction Face-Off! intervention groups, 25 minutes of each session were the same across the two intervention conditions. Instructional methods differed for the remaining 5 to 7 minutes of each session. For year 2, the activities for 5 minutes of each session differed between the two intervention conditions; students either completed activities to build fluency with measurement topics or they completed activities to consolidate conceptual understanding of the same measurement topics. In year 3, the activities for 7 minutes of each session differed between groups; one intervention condition focused on multiplicative word problems, while the other intervention condition focused on additive word problems. In year 4, the activities for 7 minutes of each session differed, during which teachers taught students to provide high quality explanations when comparing fraction magnitudes or solve fraction word problems. In year 5, the 7-minute warm-up activity differed between the two intervention conditions, during which teachers implemented the decimal magnitude or fraction applications component. In addition to Fraction Face-Off!, students in the intervention group also used their regular district math curriculum, Houghton Mifflin Math (Greenes et al., 2005) in year 1 and enVisionMATH (Scott Foresman-Addison Wesley, 2011) in years 2 through 5.
The comparison group used the regular district curriculum, Houghton Mifflin Math in year 1 and enVisionMATH in years 2 through 5. Houghton Mifflin Math included lessons on conceptual understanding and procedural calculations and focused on understanding parts of a whole. The conceptual lessons included vocabulary instruction, connections across multiple curricula (including social studies, music, and writing), guided practice, independent work, and connections to real life. The procedural calculations included calculations with proper and improper fractions and mixed numbers. The enVisionMATH curriculum included two units: 1) Understanding Fractions, and 2) Adding and Subtracting Fractions. The Understanding Fractions unit focused on understanding parts of a whole by using manipulatives and drawings to illustrate the concept, and the Adding and Subtracting Fractions unit focused on procedures with fractions. The delivery of the enVisionMATH curriculum in the comparison condition covered some more advanced topics than its delivery in the intervention condition and did not restrict the range of denominators, whereas the intervention conditions limited the range of denominators to 2, 3, 4, 5, 6, 8, 10, and 12 and the range of equivalent fractions and reducing activities to 1/2, 1/3, 1/4, 1/5, and 1/1.
The study teachers were full- or part-time graduate student employees of the research grant and included some licensed teachers. They were trained by experienced Fraction Face-Off! professional staff through a weeklong initial workshop followed by 1-hour follow-up trainings every other week. Follow-up trainings provided teachers with feedback and included problem solving about students’ challenging behavior and skill-level differences. Teachers received lesson guides for each of the 36 lessons and were expected to review, but not memorize, the guides. Before implementation, teachers practiced delivering the lesson to other teachers.

An indicator of the effect of the intervention, the improvement index can be interpreted as the expected change in percentile rank for an average comparison group student if that student had received the intervention.
For more, please see the WWC Glossary entry for improvement index.
An outcome is the knowledge, skills, and attitudes that are attained as a result of an activity. An outcome measures is an instrument, device, or method that provides data on the outcome.
A finding that is included in the effectiveness rating. Excluded findings may include subgroups and subscales.
The sample on which the analysis was conducted.
The group to which the intervention group is compared, which may include a different intervention, business as usual, or no services.
The timing of the post-intervention outcome measure.
The number of students included in the analysis.
The mean score of students in the intervention group.
The mean score of students in the comparison group.
The WWC considers a finding to be statistically significant if the likelihood that the finding is due to chance alone, rather than a real difference, is less than five percent.
The WWC reviews studies for WWC products, Department of Education grant competitions, and IES performance measures.
The name and version of the document used to guide the review of the study.
The version of the WWC design standards used to guide the review of the study.
The result of the WWC assessment of the study. The rating is based on the strength of evidence of the effectiveness of the intervention. Studies are given a rating of Meets WWC Design Standards without Reservations, Meets WWC Design Standards with Reservations, or >Does Not Meet WWC Design Standards.
