In this study, we randomly assigned 69 Grade 4 students to a writing-to-learn treatment (n = 23), comparison (n = 23), or no-treatment control (n = 23). Treatment and comparison students completed a science experiment involving balance. During the experiment, treatment students wrote four short responses and an extended response to document their…

The authors' aim was to investigate the effects of the instructional intervention on science processes skills (SPSs) of seventh-grade students. The study was designed as nonequivalent control-group pretest-posttest, and it was carried out with 43 students. Participants were chosen according to the convenient sampling method. The authors collected…

In this quasiexperimental study, the authors investigated the effects of university within school partnership model, within which faculty members acted as teacher-researchers to improve fractional knowledge among middle school (Grades 5-8) students. Students in nine Grade 6 mathematics classes from two public middle schools in Turkey were assigned…

The purpose of this study was to investigate the effect of 5E learning cycle model oriented instruction (LCMI) on 11th-grade students' conceptual understanding of acids and bases concepts and student motivation to learn chemistry. The study, which lasted for 7 weeks, involved two groups: An experimental group (LCMI) and a control group (the…

The authors compared the mental computation performance and mental strategies used by an experimental Grade 2 class and a control Grade 2 class before and after instructional intervention. Results indicate that students in the experimental group had better performance on mental computation. The use of mental strategies (counting, separation,…

In 2 experiments the authors investigated whether assigning a perspective to middle school students prior to reading a long informational text would improve their reading comprehension. Pretest-posttest control group designs were employed in both experiments, in Experiment 1 (n = 146 fifth- and sixth-grade students) and in Experiment 2 (n = 83…

The authors examined the impact of a supplemental reading course on 462 sixth-grade students' reading engagement and performance as compared with 389 students in a control group. They further explored students' cognitive strategy use through think aloud processes with a subset of students who participated in the intervention.…

A cognitive and a guidance dimension can describe the support of students' conceptual understanding in inquiry-based science education. The role of guidance for student learning has been intensively discussed. Furthermore, inquiry learning may pose particular challenges to students with low language proficiency. The present intervention in primary…

The authors describe results from a study of a middle school mathematics formative assessment strategy. They employed a randomized, controlled design to address the following question: Does using our strategy improve student performance on assessments of key mathematical ideas relative to a comparison group? Eighty-five teachers and 4,091 students…

The authors compared the performance of students who received integration of number sense activities in instruction with students who received instruction using regular mathematics textbooks. Two classes of third-grade students (N = 60) were randomly assigned to experimental and control groups. Students in each group were given a pretest, post I…

The authors used a randomized design to investigate the effects of an enriched reading program, Schoolwide Enrichment Reading Model (SEM-R), with blocks of independent reading on oral reading fluency (ORF), reading comprehension, and attitudes toward reading for students in Grades 3-5. The authors used SEM-R in comparison with basal reading…

The author examined the effectiveness of a vocabulary intervention that employed structured, supplemental story read-alouds and related oral-language activities. Within each of 7 Title I schools across 2 sites, 15 third-grade teachers were randomly assigned to either use the intervention (treatment condition) or continue their usual practice…

The authors used the Motivated Strategies for Learning Questionnaire to investigate the effectiveness of problem-based learning (PBL) and traditional instructional approaches on various facets of students' self-regulated learning, including motivation and learning strategies. Participants included 61 tenth-grade students from 2 intact classes…
