Under each factor, observed variables oritems were developed to measure these unseen (or latent) factors.The purpose of this study is to re-evaluate the psychometric soundness of the DET survey Page 22.1616.2using new data collected from a larger and a relatively more diverse group of elementaryteachers.

The framework was used extensivelywhen structuring assessment, both on program assessment and classroom assessment. Forexample, the framework was used as a framing concept in evaluating young children’s work15 and in making sense of complex assessment 16. Cognition refers to beliefs about how students learn 14.

This projectinvolves motivating students to develop an academic map/career plan for themselves byobserving and interviewing successful engineers in different fields, creating overviewprofiles for each of them, and studying these profiles to determine how they connect withtheir career intentions.A detailed explanation of the Engineering your Future Project and how it fits into the ES100 curriculum is given in this paper. Results from qualitative and quantitative evaluationof the project will be presented. In addition, since the project was also added to one of theES 100 sections taught to

This is LED in S/D Circuit (b)possible because the diffusion constant of phosphorous in SiO2 isvery low as compared to that in Si. Thus, the presence of SiO2makes sure that the n-type impurities are introduced in red areas(S/D) only.

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

Figure 8 Figure 9ResistanceThe conductive dough serves as a wire with a built-in resistor. Because it is a semisolid, the Page 22.672.6resistance in the circuit increases as the length of the dough increases. The circuit demonstratedin Figure 10 is essentially the same as the circuit shown in Figure 1, but it uses longer pieces ofdough as wires. Since the resistance of the dough “wire” increases with length, the
