In central and northern Florida, 149 third-fifth grade teachers from 32 public schools (drawn from nine school districts) participated in this study.
The study report did not include information about proportion of students who were male vs. female, or information about race/ethnicity of the students in the sample. The authors reported that the study sample was typical of public elementary schools in central and northern Florida, however, the authors did not provide the proportion of students who were eligible for free or reduced price lunch, or English language learners, or had individual education plans.
Teachers in the intervention group participated in a professional development program on how to implement Cognitively Guided Instruction (CGI) in their classrooms to improve mathematics achievement. In grades 3-5, the CGI program focused on two research-based frameworks which help teachers to elicit children's thinking about the structure of a mathematical problem and strategies on how to solve those problems. Teachers learn how to use information about students' reasoning and developmental process to help them understand fractions, fraction operations, whole number multiplication and division, and base ten concepts for whole numbers and decimals. The professional development program occurred for five consecutive 7-hour days in summer 2015, two consecutive 6-hour days in fall 2015, and two consecutive 6-hour days in winter 2015.
The comparison group implemented business-as-usual practice during the study period, and were invited to participate in the intervention once the study period was completed.
The CGI professional development program was delivered by certified CGI instructors under the direction of Dr. Linda Levi, who co-authored the CGI curriculum in several books.
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.

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.
