Study Details
Setting
The study took place in 40 kindergarten through grade 4 classrooms across six schools in one large school district in the panhandle region of Florida.
Study sample
The sample included students who were 75% White, 10% African American, and the remaining students belonged to other ethnicities. Approximately 50% of students qualified for free- and reduced-price lunch.
Intervention Group
CALI is a content-based method for literacy instruction that was delivered during literacy blocks. The literacy block, as described by the study authors, is a 1- to 2-hour block of time dedicated to reading. The intervention includes two social studies and two science units. Each unit was delivered over a 3-week time period, generally 4 days per week for approximately 15 to 20 minutes per session. The intervention was delivered by teachers specifically hired by the research team. These teachers were either certified or attending university programs to become certified. Intervention teachers were carefully monitored to ensure that they were implementing the program with fidelity. The project director provided ongoing feedback and support when it was observed that elements of the lesson were not being implemented as intended. Instruction was provided in small groups of up to five students that were formed based on students’ passage comprehension scores at pretest. One group had passage comprehension scores below grade level (standard score < 90), a second group had passage comprehension scores at grade level (standard score between 90 and 110), and a third group had passage comprehension scores above grade level (standard score above 110). The intervention is designed to change groups over time to reflect changes in student achievement; however, in this study, students remained in their original groups throughout the school year. In addition, classroom teachers covered science and social studies topics in their regular classroom programming outside of the literacy block, focusing on topics similar to content included in the CALI intervention. The researchers thus presume that intervention group youth had more exposure to social studies and science content, but less time on core reading instruction than comparison group youth.
Comparison Group
Students in the comparison condition received business-as-usual instruction from the classroom teacher during the literacy block. Based on researcher observations, most of the literacy block instruction for the comparison condition used the Houghton Mifflin literacy curriculum without a focus on science or social studies. Although not observed by the researchers, intervention and comparison group classroom teachers reported that they followed the Florida Sunshine State Standards for social studies and science using Scott Foresman curricula. These standards covered content similar to the CALI curriculum.
Support for implementation
Teachers were hired by the research team to implement the intervention. These teachers were trained in a full day workshop and participated in weekly project meetings. The project director observed teachers in the first week of implementation and observed the teachers and provided feedback until they were implementing the intervention as intended. Then teachers were observed monthly. Intervention group classrooms also still had their regular classroom 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.

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 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.
