Santa Ana, California has the highest teenage birth rate in Orange County, USA, at 28.2 per 1,000 women aged 15-19 as compared to 12.0 per 1000 women of similar age elsewhere in the county. In the light of this disparity, University of California Irvine medical students surveyed a convenience sample of 9th grade students (aged 14-15 years) in…

There is a need for research-informed instructional approaches that promote school students' deep conceptual understanding of abstract geological concepts. Given that a type of learner-constructed stop-motion animation, 'slowmation', has been shown to offer affordances for learning in science preservice teacher education, we extended its…

In this study, a progressive-learning approach to physics, based on knowledge-building pedagogy, was compared to a content-centered approach in which explanations, experiments, and discussions are centered on the transmission of knowledge. Forty-six students attending the first year of high school participated in this study over a whole school…

The purpose of this study is to research the effects of traditional and web-assisted conceptual change texts for the subject of water chemistry on the success, conceptual errors and permanent learning of students. A total of 37 8th graders in a secondary school of Samsun participated in this study which had a random experimental design with…

Main aim of this study is to examine the influence of computer-assisted roundhouse diagrams on high school 9th grade students' academic achievements in the subjects of "Force and Motion". The study was carried out in a public high school in Diyarbakir the province in the Southeast of Turkey. In the study, the "pre-test-post-test…

The present study examines the effects of different study tasks on the acquisition of knowledge about acids and bases in a computer-based learning environment. Three different task formats were selected to create three treatment conditions: learning with gap-fill and matching tasks, learning with multiple-choice tasks, and learning only from text…

This article presents a meta-analysis of experimental and quasi-experimental studies in which intermediate and secondary students with learning disabilities were taught science content through the use of graphic organizers (GOs). Following an exhaustive search for studies meeting specified selection criteria, 23 standardized mean effect sizes were…

This study investigates the effect of materials developed based on conceptual change approach on 9th grade students'achievement in the subject of fractions. With this aim, a worksheet, conceptual change text and a two-stage performance test on the subject of fractions were developed. Quasi-experimental research model was used in the study.…

Although much is known about how students perform on standardized tests, little research exists concerning how students think and process while taking such tests. This mixed methods action research study was designed to investigate if a constructivist approach to test preparation could yield improved results for 37 English language arts freshmen…
