Generation Science Standards1 (NGSS) and an all-out push by President Obama andthe Department of Education seek to reform science education by introducing engineeringcontent and practices into Kindergarten through 12th-grade instruction. Science teachers acrossthe grades are tasked with including engineering in their science curricula creating the need forresearch on NGSS execution and roadblocks. This qualitative study stemmed from anexperienced high school physics teacher’s unexpected change in co-planned engineeringinstruction during a math and science enrichment camp. In an attempt to understand Evan’s*actions, this study examined the origins of and tensions within Evan’s engineering educationepistemology (EEE). My main research questions were

Programming 1 and Programming 2 at OhioNorthern University has used the term project theme of developing K-12 educational softwarefor many years, but until 2014 the project was done without the benefit of having a client tosatisfy. Consequently, the instructor could only provide feedback on the technical aspects of theimplementation, and most of the feedback was summative. With the recent establishment of anengineering education degree program, the opportunity arose for providing the programmingstudents with a meaningful client-driven design experience. The engineering education majors,acting as clients, developed lesson plans for STEM outreach programs as part of a fall semestercourse that were afterwards supplemented by software applications

It begins with a stage of concrete experience,which serves as the foundation for learning, and is then followed by reflective observation, inwhich the learner intentionally reflects on the concrete experience, abstract conceptualization, inwhich they generalize what they have learned, and a planning stage in which they plan for the nextconcrete experience. These steps are

The data analysis typicallyincludes determination of experimental error, consistency of data and validity of test results.This definition differs from the broader field of statistical design of experiments in the sense thatstudents are not expected to perform comprehensive cycles of investigation that involvescomparison of various treatments and empirical studies
