The integration of scientific modeling into science teaching is key to the development of students' understanding of complex scientific phenomena, such as genetics. With this in mind, we conducted an introductory hands-on module during an outreach gene technology laboratory on the structure of DNA. Our module examined the influence of two model…

This study investigated how students' and teachers' pedagogical roles in mobile learning moderated the relationship between high school students' perceived usefulness of mobile technology and the actual use frequency, as well as how students' perceived usefulness impacted their physics learning achievement. We examined 803 high school freshmen who…

The goal of this study was to investigate the timing of online homework completion and its effects on student performance. Data was collected from two large, first-semester general chemistry sections at a southwestern university. Specifically, this study aims to explore the link between when students complete their homework relative to the date…

As mobile technology becomes more frequently used in science learning, understanding the relationship between student outcomes and the technology's pedagogical features is drawing increasing attention. This study focuses on one pedagogical feature--"who led the use." We first categorized 15 specific uses of mobile technology into three…

In four studies on the use of student response systems, clickers, we sought to understand whether the use of clickers would impact students' attitudes toward the use of technology for instruction and achievement on examinations. While the results varied some by study, overall, the results revealed no significant changes in the already…

Mass media, particularly television, influence public conceptions and attitudes toward learning science. The discovery of an original method that does not rely on self-reported viewing habits to measure the impact of television on students' performance in science arose from a study of a unit on electricity in a Physics course. In determining the…

This study investigated the effects of problem-based learning on students' beliefs about physics and physics learning and conceptual understanding of Newtonian mechanics. The study further examines the relationship between students' beliefs about physics and their conceptual understanding of mechanics concepts. Participants were 124 Turkish…
