The effectiveness of an experimental middle school fraction intervention was evaluated. The intervention was centered on the number line and incorporated key principles from the science of learning. Sixth graders (N = 51) who struggled with fraction concepts were randomly assigned at the student level to the experimental intervention (n = 28) or…

The effects of a mathematical problem-solving intervention on students' problem-solving performance and math achievement were measured in a randomized control trial with 1,059 7th-grade students. The intervention, "Solve It!," is a research-based cognitive strategy instructional intervention that was shown to improve the problem-solving…

This experimental study evaluated the effectiveness of a research-based intervention, schema-based instruction (SBI), on students' proportional problem solving. SBI emphasizes the underlying mathematical structure of problems, uses schematic diagrams to represent information in the problem text, provides explicit problem solving and metacognitive…

Results from randomized controlled trials of learning strategies instruction with 375 adult basic education participants are reported. Reading outcomes from whole group strategic instruction in 1 of 4 learning strategies were compared to outcomes of reading instruction delivered in the context of typical adult education units on social studies,…

American Institutes for Research (AIR) conducted an evaluation of the effect on struggling readers of implementing the READ 180 reading intervention in five participating schools in Milwaukee Public Schools (MPS) under a Striving Readers grant from the U.S. Department of Education. The evaluation used an experimental design in order to produce a…

First-year students experience academic, social, and emotional adjustments as they transition to college. First-year experience courses support students in this transitional phase by helping them integrate into the campus environment and by teaching them college-appropriate learning strategies. This study explored the role that participation in a…

One hundred forty fourth graders were asked to solve proportion problems about juice-mixing situations both before and after an intervention that used a manipulative model or other materials in three experiments. Results indicate different approaches appear to be necessary to facilitate children's proportional reasoning, depending on the reasoning…

Effectiveness of a classwide peer tutoring program was studied for low achievers with and without learning disabilities and average achievers in 20 elementary school intervention classes and 20 control classes. All types of learners in peer tutoring classrooms demonstrated greater reading progress regardless of which of three measures was used.…
