Assessing Mechanistic Reasoning: Supporting Systems Tracing, Paul J. Weinberg

Journal of Pre-College Engineering Education Research (J-PEER)

Reasoning about mechanism is central to disciplined inquiry in science and engineering and should thus be one of the foundations of a science, technology, engineering, and mathematics education. In addition, mechanistic reasoning is one of the core competencies listed in the Next Generation Science Standards (NGSS) Engineering Concepts and Practices (NGSS Lead States, 2013). Mechanistic explanations focus on the processes that underlie cause–effect relationships and consider how the activities of system components affect one another.

While some assessment work has been accomplished in engineering education, to date mechanistic reasoning is an area where limited assessment development has been accomplished for …

Exploring Problem-Based Learning For Middle School Design And Engineering Education In Digital Fabrication Laboratories, Monica M. Chan, Paulo Blikstein

Interdisciplinary Journal of Problem-Based Learning

This is a research study of design and engineering classes that use a problem-based learning (PBL) approach in digital fabrication makerspaces in two middle schools. In these studies, teachers employ a PBL approach and provide an ill-structured problem scenario to facilitate design and engineering lessons in the FabLab (fabrication laboratory). Students in each school tackled different challenges that they defined for themselves in groups. This study provides examples of student-student interactions separated into key themes—defining specifications with teammates, personal exploration, and communication about discoveries. This study also provides examples of teacher-student interactions, and themes include demonstrations with tangible objects, discussing …

Ascertaining The Impact Of P–12 Engineering Education Initiatives: Student Impact Through Teacher Impact, Marissa H. Forbes, Jacquelyn F. Sullivan, Denise W. Carlson

Journal of Pre-College Engineering Education Research (J-PEER)

The widespread need to address both science, technology, engineering, and math (STEM) education and STEM workforce development is persistent. Underscored by the Next Generation Science Standards, demand is high for P–12 engineering-centered curricula. TeachEngineering is a free, standards-aligned NSF-funded digital library of more than 1,500 hands-on, design-rich K–12 engineering lessons and activities. Beyond anonymous site-user counts, the impact of the TeachEngineering collection and outreach initiatives on the education of children and their teachers was previously unknown. Thus, the project team wrestled with the question of how to meaningfully ascertain classroom impacts of the digital engineering education library and—more broadly—how to …
