is not simultaneously accompanied by (or occasioned through) an extension of the student‟s use of language. Through this elaboration of discourse new thinking is brought into being, expressed, reflected upon and communicated. This extension of language might be acquired, for example, from that in use within a specific discipline, language community or community of practice, or it might, of course, be self-generated. It might involve natural language, formal language or symbolic language.8” The language extension of engineers learning to solve problems includes some natural language, formal disciplinary language, and

meet the above goals were:i. Emphasis on self-validation techniques. The instructor emphasized identifying the order of magnitude, direction and other aspects of believability of a mathematical answer. Students were required to estimate answers before attempting homework problems and reflect on confidence afterwards. Students were further encouraged to identify reasons when they DID NOT have confidence in answers on exam questions and some missed points were given back back when a student offered a rationale for why an answer was wrong that displayed good conceptual intuition.ii. Design Competition. Students were required to build a small mobile, sculpture or device that displayed their

develop proper conceptual understanding. Ourengineering students seemed motivated by the experiments, and a great deal of good discussioncould be heard as we walked around the room. In future work, we hope to ascertain exactlywhen students seem to understand the concepts, and the exact components necessary to make aneffective inquiry-based learning activity for dynamics.Acknowledgements: Support for this work was funded by the National Science Foundation,NSF 1044282, Using Inquiry-Based Activities to Repair Student Misconceptions in EngineeringDynamics.

reflect student learning gains. Many assessment studies wereperformed with neither a control group nor random assignment of student participants, omissionswhich presented a significant threat to their validity. Based on our research findings descried inthis paper, we suggest that particular attention be paid to control students’ cognitive load at anappropriate level when designing and implementing CSA modules and programs in order tomaximize student learning outcomes.IntroductionIn learning many engineering subjects, students must develop skills to visualize the motion ofobjects over space and time. With advances in computer technology and communicationnetworks, more and more engineering educators have employed web-based computer simulation

. Though no calculations were performed in Page 23.433.7this demonstration, students were asked to reflect on their hypothesis from the previousexperiment on creep and consider the design implications with different materials that undergotemperature fluctuations.Lab 6: Stress ConcentrationIn Lab 6 students explored the effects of shape on the concentration of stresses. This lab waslargely a demonstration and observation experiment. Students were given two templates andasked to use those templates to cut out standard shapes (dog-bone and square-edge) of aluminumfoil. Using the same hanging setup as the copper wire tension experiment, students
