“Technology Education/Pre-engineering education” (TE/PreEE)program and has its roots in industrial arts education dating back to the 1930s. More detaileddescriptions of each of these programs have been previously reported.[1-3] Both programsrequire substantial coursework in all four elements of STEM, as well as integrated-STEM(i.e.- how to use multiple STEM elements together in K-12 curriculum/activities). Studentsin both programs also acquire substantial experience in integrating non-STEM subjects withSTEM subjects. In 2006 our department completed a redesign of our “TechnologyEducation” curriculum to integrate more M&S into our Technology & Engineering (T&E)courses, resulting in our current “pre-engineering” curriculum.

He used robotics as anavenue for students to study engineering concepts and skills, namely: design processes,Computer Aided Design (CAD), electronics (sensors) and programming. The class weexamined was a Robotics I class taken by students ranging from 9th-12th grade.

Design education and curriculum theoryThe concept of curriculum alignment provides a sound rationale for integrating design across thecurriculum. The idea that curriculum, instruction, and assessment should be conceived as partsof a cohesive whole (or system) forms the core principle of curriculum alignment. Each of thesethree component parts – curriculum, instruction, and assessment – must be viewed relative to theothers if curriculum alignment is to take place. In this
