Teaching argumentation with appropriate activities and strategies would support a wide range of goals in science education. Though science labs have been suggested and employed for argumentation activities, such educational expenditures are likely to be beyond the means of most schools in under-resourced areas. Due to the lack of appropriate…

Researchers from multiple perspectives have shown that young students can engage in the scientific reasoning involved in science experimentation. However, there is little research on how well these young students learn in inquiry-based learning environments that focus on using scientific experimentation strategies to learn new scientific…

This study hypothesized that increased intensity of graphic information, presented in computer-generated instruction, could be differentially beneficial for students with hyperactivity and inattention by improving their ability to sustain attention and hold information in-mind. To this purpose, 18 2nd-4th grade students, recruited from general…

The present experiment investigated the effect of three different presentation modes in children's vocabulary learning with a self-guided multimedia programmes. Participants were 135 third and fourth grade children who read a short English language story presented by a computer programme. For 12 key (previously unknown) words in the story,…

The goal of this study is to develop a virtual farm for educational applications. Users can play the role of a farmer by planting vegetables and raising poultry on the virtual farm to observe their growth through online learning activities. The virtual farm possesses educational and entertaining functions, and it is designed by simulating the real…

This project was designed to test Mayer's multimedia theory in an elementary school to improve students' mathematics learning for low-income children. The study designed and developed two multimedia mathematics experiments in 3rd grade: 9's multiplication experiment and geometric solids experiment. The two experimental lessons were implemented in…

Although much contemporary thinking leads to the expectation that communication technology, such as video streaming, enhances educational performance on the average, a dearth of strong evidence consistent or inconsistent with this claim precludes a thoughtful evaluation of it. A series of experiments designed to examine this proposition…

The Technology Enhanced Elementary and Middle School Science II project (TEEMSS), funded by the National Science Foundation, produced 15 inquiry-based instructional science units for teaching in grades 3-8. Each unit uses computers and probeware to support students' investigations of real-world phenomena using probes (e.g., for temperature or…
