Wang, Tzu-Ling; Tseng, Yi-Kuan – International Journal of Science and Mathematics Education, 2018
The purpose of this study was to investigate the relative effectiveness of experimenting with physical manipulatives alone, virtual manipulatives alone, and virtual preceding physical manipulatives (combination environment) on third-grade students' science achievement and conceptual understanding in the domain of state changes of water, focusing…

Grotzer, Tina A.; Powell, Megan M.; Derbiszewska, Katarzyna M.; Courter, Caroline J.; Kamarainen, Amy M.; Metcalf, Shari J.; Dede, Christopher J. – Technology, Knowledge and Learning, 2015
Reasoning about ecosystems includes consideration of causality over temporal and spatial distances; yet learners typically focus on immediate time frames and local contexts. Teaching students to reason beyond these boundaries has met with some success based upon tests that cue students to the types of reasoning required. Virtual worlds offer an…

Samon, Sigal; Levy, Sharona T. – Science Education, 2017
The study explores how a complexity approach empowers science learning. A complexity approach represents systems as many interacting entities. The construct of micro-macro compatibility is introduced, the degree of similarity between behaviors at the micro- and macro-levels of the system. Seventh-grade students' learning about gases was studied…

What Works Clearinghouse, 2014
This study examined how using two different ways of displaying the solar system--a true-to-scale mode vs. an orrery mode--affected students' knowledge of astronomical concepts. Solar system displays were presented in a software application on a handheld tablet computer. In the true-to-scale mode, users navigated a simulated three-dimensional solar…
