Physical and virtual labs have unique capabilities that can influence how students learn from them. The purpose of this study was to examine the effect of physical and virtual manipulatives on students' learning of heat and temperature and to examine the influence of various combinations of physical and virtual manipulatives. A total of 205…

Science is one of the most important subjects for students at all educational levels. To promote engagement, hands-on experiments can provide a 'realistic and exciting experience of the content' (Holstermann, Grube and Bögeholz, 2010: 744) and hopefully facilitate motivation. In this article, George Stylos and Konstantinos T. Kotsis present four…

Comics have an important role in non-formal learning environments. However, how comics may be effective teaching/learning activitities in formal education is an ongoing debate in literature. The purpose of this study is to create and evaluate a series of instructional comics about heat related concepts to be used as teaching/learning activities in…

One tried-and-true way to hook students' attention and promote long-lasting understanding is to sequence science instruction in an explore-before-explain instructional sequence. In these lessons for the second through sixth grade band, elementary students investigate the interaction between "cold" and "hot" substances and…

The purpose of this study was to explore how examples used in teaching may influence elementary school students' conceptions of evaporation and boiling. To this end, the examples traditionally used to explain evaporation and boiling in Korean 4th grade science textbooks were analyzed. The functions of these published examples were explanation…

This paper reports the findings of a study exploring the use of a software package to help pupils understand particulate explanations for melting and evaporation below boiling point. Two matched classes in a primary school in Greece (ages 11-12, n = 16 and 19) were involved in a short intervention of six one hour lessons. Covering the same…

National Aeronautics and Space Administration (NASA) Engineers at Marshall Space Flight Center, Dryden Flight Research Center, and their partners at other NASA centers and in private industry are currently developing X-33, a prototype to test technologies for the next generation of space transportation. This single-stage-to-orbit reusable launch…

The purpose of this study was to investigate how concept cartoons, together with other diagnostic and scaffolding tools, could be used in formative assessment, to stimulate talk and argumentation among students in small groups, as part of peer-assessment and self-assessment; and to provide diagnostic feedback about students' misconceptions to the…

In sixth grade, students understand that Earth gets visible light from the Sun, but students may also believe the Earth gets heat from the Sun. This last part is incorrect because the Sun is too far from the Earth to heat it directly. So, how does the Sun heat the Earth? When light strikes an object, it can be reflected or absorbed. Absorbed light…

National Aeronautics and Space Administration (NASA) Engineers at Marshall Space Flight Center, and their partners at other NASA centers and in private industry, are designing and beginning to develop the next generation of spacecraft to transport cargo, equipment, and human explorers to space. These vehicles--the Ares I and Ares V launch…
