Background: There is a need to find ways of productively engaging K-12 students with engineering design. I investigate a new class of physical models, referred to as Improvable Models, as scaffolds for helping middle school students productively engage in engineering design practices. Purpose/Hypothesis: The purpose of this study is to answer two…

Youth involved in 4-H projects have been engaged in science-related endeavors for years. Since 2006, 4-H has invested considerable resources in the advancement of science learning. The new Minnesota 4-H Science of Agriculture Challenge program challenges 4-H youth to work together to identify agriculture-related issues in their communities and to…

My research comparing different curriculum models has confirmed the necessity of using STEAM within a science classroom to promote conceptual understanding of the content. The curriculum inquiry model of teaching science using the scientific method is insufficient to promote academic growth compared to the STEAM curriculum model that utilizes the…

Engineering-based modeling activities provide a rich source of meaningful situations that capitalize on and extend students' routine learning. By integrating such activities within existing curricula, students better appreciate how their school learning in mathematics and science applies to problems in the outside world. Furthermore, modeling…

Afterschool programs are currently conceptualized in two ways. One is represented by "expanded learning," which includes a wide range of content-rich opportunities in the hours outside of school, including summer camps. The operating assumption is that, in structured out-of-school time (OST) programs, children can learn concepts or develop…

Meat thermometers can be awkward to use in terms of placement and avoidance of bones. Because of these problems, each year 30 million Thanksgiving turkeys have a built-in thermometer that pops up when the turkey is properly cooked. Turkey timers are an example of how engineering solved a common, everyday problem. The following 5E learning cycle…
