This quasi-experimental study investigated how explicit instruction about multiple modes of representation (MMR) impacted grades 7 (n = 61) and 8 (n = 141) students' learning and multimodal use on end-of-unit assessments. Half of each teacher's (n = 3) students received an intervention consisting of explicit instruction on MMR in science…

The purpose of this research was to evaluate a collaborative concept-mapping technique that was integrated into coteaching in fourth-grade science classes in order to examine students' performance and attitudes toward the experimental teaching method. There are two fourth-grade science teachers and four classes with a total of 114 students…

This study assessed the influence of using mind maps as a learning tool on eighth graders' science achievement, whether such influence was mediated by students' prior scholastic achievement, and the relationship between students' mind maps and their conceptual understandings. Sixty-two students enrolled in four intact sections of a grade 8 science…

The purpose of this study is to analyze items that exhibit gender-related Differential Item Functioning (DIF) in Mathematics in Jordan. Data was taken from the TIMSS 1999 of Jordan, which includes responses of 5, 299 eighth grade students. Mantel-Haenszel (MH) DIF procedure was applied to 124 multiple-choice items. The results showed that 37 items…

This exploratory case study investigates relationships between use of an inquiry-based instructional style and student scores on standardized multiple-choice tests. The study takes the form of a case study of physical science classes taught by one of the authors over a span of four school years. The first 2 years were taught using traditional…
