In whatever setting the knowledge of engineering techniques, skills, and tools aredeveloped the focus needs to be on improving students’ understanding and appreciation of thetechnological world while deepening their knowledge in mathematics and science.The understanding of the central role of materials and their properties is an essential feature ofengineering solutions15. Design activities require learners to notice and reflect on the structure,function, and behavior of a process, a device, or a natural phenomena20. Scientific knowledgeinforms engineering design and many scientific advances would not be possible withouttechnological tools developed by engineering1. However, most people have little

This information was presented to the projectleadership team (5 researchers). Based on this information, the two studies and report citedabove, and the need to achieve additional focus for the assessment process, the team decided tofocus on a smaller set of primary concepts that are central to engineering, important at thesecondary level, and can provide strong links to science education. Four primary conceptsemerged and sub-concepts were identified under these concepts serving to highlight keycomponents. The concepts and sub-concepts are: • Design

Children (and adults) often champion their own ideas, withoutadequately considering designs of others or without conducting “objective” analyses.To encourage students to analyze their various solutions objectively and determine which bestmeets the challenge’s criteria, EiE design challenges aim to have students collect both qualitativeand quantitative data during testing. Materials ask students to reflect upon the needs of the designand assess how well each solution meets it. Thus, instead of children’s preconceptions,popularity, or perceived “smartness” driving decisions, more objective and impartial data areavailable to be considered.EiE strives for quantifiable tests: presenting results as a number

guided discovery approach posits that any subject can be taught effectively in someintellectually honest form to any child at any stage of development. A constructivist approach tolearning and teaching is based on the notion that learners construct their own knowledge ratherthan knowledge being transferred into learners‟ brains.8-10 Learners‟ construction of knowledgeis based on their past knowledge, the timeliness of new knowledge, and the learner‟s ability tounderstand the connections. This process forces learners to either modify existing knowledge ordevelop new knowledge. Learning experiences based on constructivism are reflected in popularinstructional strategies such as inquiry based learning11-12, problem based learning (PBL) 13-14

First, PLTW in Iowa tends toattract white males and students who have higher achievement in mathematics and science injunior high. The percentages of women who enter PLTW are approximately the same percentagethat enters mechanical and electrical engineering programs (Walcerz, 2006). Overall, theselection bias was rather significant, with participants scoring between 0.72 and 0.9 standarddeviations higher on mathematics and science scores prior to entering PLTW. We stronglysuggest that future research on PLTW needs to reflect selection bias in their analysis of theprogram. We controlled for selection bias using propensity score matching that predicted entry

Based on this information, they refine their concept and construct an improved design. Through this process, students are introduced to key components of the engineering design process (Figure 1), including methods for quantitatively describing objectives (maximize volume while minimizing drag); generating and selecting concepts; testing, evaluating and refining the concepts; and selecting a final design.

ConclusionsIn this paper, we share our experiences related to the development of teacher workshops andstudent camps focused on educational robotics based on an active learning model. Ourconclusions can be summarized as follows:  Understanding a concept entails having a mental model that reflects the structure of the concept and its relationship to other concepts. Therefore, presenting organized knowledge through concepts that are combined to form propositions that show the relationship among concepts is essential.  Learning is an active and continual process, where knowledge is constructed, continually updated, and

The curriculum built upon this skillwhile adding various application problems, discussing engineering drawings, and focusing onpattern development. Approximately half way through the curriculum, students were exposed towireframe geometry as they concentrated on two and three coordinate drawings. Transformationsbecame integral at this point as students used translations, dilations, rotations, and reflections toview objects as they are rotated about axes and investigated cross-sections.3 Data
