The purpose of this study is to present an activity based on integrated Science, Technology, Engineering, and Mathematics [STEM] approach, its implication, steps, and necessary documents. The activity started with a daily-life problem stated in the STEM literature. Later, activity worksheets were provided. Learners were asked to design a process…

A rattleback is a well-known physics toy that has a preferred direction of rotation. If it is spun about a vertical axis in the "wrong" direction, it will slow down, start rocking from end to end, and then spin in the opposite (i.e. preferred) direction. Many articles have been written about rattlebacks. Some are highly mathematical and…

Although most innovative professional development encourages reflective dialogue among teachers, we still know very little about how such dialogue enables teacher learning.

Understanding how to interpret and manipulate large data sets is increasingly important today; however, this experience has been slow to trickle down to the typical undergraduate student. Here, we describe the implementation of a project-based learning experience that uses portable air sensors for the real-time measurement of carbon dioxide,…

Teaching in a democracy is challenging and filled with dilemmas that have no easy answers. For example, how do educators meet their responsibilities of teaching civic norms and dispositions while remaining nonpartisan? "Democratic Discord in Schools" features eight normative cases of complex dilemmas drawn from real events designed to…

When there is a limit on the amount of information available in a classroom, the students need to depend on the teacher as the master of information. Conversely, when accurate information is widely available, conveniently organized, and easily accessed, then the nature of the learning that takes place can resemble more what the AHA now advocates:…
