Strong information literacy, collaboration, and argumentation skills are essential to success in problem-based learning (PBL), and computer-based scaffolding plays a key role in helping students enhance these skills. As students search for information, identify root causes, and propose problem solutions, they are faced with choosing among…

Teaching the fundamentals of chemical kinetics on the college level is challenging to teachers and students alike due to its abstract nature of concepts and limited connection with real context applications. This study consisted of two phases starting with designing a chemistry education for the sustainable development-based learning environment…

Guided by the Next Generation Science Standards and elements of problem-based learning, four human-environment systems simulations are described in brief--carbon, energy, water, and watershed--and a fifth simulation on nitrogen is described in more depth. These science, technology, engineering, and math (STEM) education simulations illustrate…

This paper reports on a project in which students designed, constructed and tested a model of an existing early warning system with simulation of debris flow in a context of a landslide. Students also assessed rural community members' knowledge of this system and subsequently taught them to estimate the time needed for evacuation of the community…
