Cross Case Study Of An Elementary Engineering Task, John Heffernan

Doctoral Dissertations

Designerly play has been identified as a fundamental component of childhood learning (Baynes, 1994; Petroski, 2003). However, as students enter grade one and beyond, the increasing academic focus has resulted in the loss of opportunities for designerly play (Zhao, 2012). At the same time, there are increasing calls to increase the number, skill, and diversity of STEM workers (Brophy, Portsmore, Klein, & Rogers, 2008). The robotics based Elementary Engineering Curriculum (Heffernan, 2013) - used by students in this study - and other similar projects have the potential to increase the STEM pipeline but elementary engineering is not well-understood. Research is …

The Impact Of Beliefs And Curricular Knowledge On Planning For Science: A Multisite Case Study Of Four Teachers, Jessica L. Horton

Doctoral Dissertations

This descriptive multisite case study details how the beliefs and curricular knowledge of four science teachers in a southeastern school district affected their planning for science instruction.

Through the analysis of interviews, think-aloud planning records for one unit of instruction, and related documentation, categories were identified and connections drawn to how their beliefs and knowledge influenced planning for instruction.

The four teachers in this study jointly expressed certain beliefs about how students best learn science. They expressed beliefs that students best learn science through hands-on activities, through discourse, and by building the student’s knowledge base. The teachers also expressed beliefs …
