Abstract

Capstone Projects, CTC 490, is a mandatory course for all Civil Engineering Technology students during their senior year. This specific course is designed to apply cumulative experiences gathered from wide range of courses in the curriculum. The students analyze and design real life civil engineering project, write a written report followed by an oral presentation. However, during the COVID-19 pandemic, student learning outcomes were significantly disrupted as the plan of study changed to online mode from March 2020. The purpose of the current study is to document the students' learning experiences of the capstone design course during the pandemic year. As the course is so comprehensive in nature, wide range of student learning assessment is possible from this course. Data were collected from Fall 2020 and Spring 2021 semester to assess the student outcomes in the category of communication with the teammates, fulfill roles and responsibilities, and listening to the teammates. The scales of one to four (1-not acceptable, 2- below standards, 3- meets standards, 4- exemplary) were chosen so that the instructor had a clear view to make a decision whether the expectations were met or not. The measure of successful performance in each attribute was achieving a score of 3 or 4. A benchmark of 70% was selected to gage the level of success. The results showed that the student outcomes were impacted most in the communications category. The level of success in the capstone rubric were documented and connected with the related program outcomes of the ETAC/ABET criteria. Outcomes of this study will be helpful in planning to teach such kind of course in situation like pandemic or other situations out of our control. [ABSTRACT FROM AUTHOR]

Abstract

Effect of natural impurities induced in repeated melting is investigated on thermo-mechanical and reflectance characteristics of commercially available pure copper. Copper samples of three different material characteristics are prepared, which are obtained from direct copper ingot, from melted copper and finally from re-melted copper. Samples are then cold rolled in three different stages as well as age hardened by isochronal and isothermal annealing. Series of experiments are then conducted to measure the changes in microhardness, thermal conductivity, reflectance and microstructure of the samples as a function of with and without melting. Most of the thermal and mechanical properties are found to be affected quite significantly by the melting impurities especially when the samples are cold rolled together with age hardening. The reflectance spectrum is also found to be changed with the increase of impurities induced by repeated melting of copper. [ABSTRACT FROM AUTHOR]
