Our assessments of this scaffold suggest that, over all, the instructional technology components are supporting student learning in the intended ways [2, 3]. Our prior studies, however, have evaluated the scaffold with the data aggregated for both genders. In this study we look at whether or not men and women derive different benefits from the instructional technologies. Our data presents an analysis of survey data on instructional technology perceptions and usage over several semesters in undergraduate courses. The impact of students’ attitudes toward math and technology learning more generally is also considered. Our findings are useful in developing instructional strategies that enable the most effective use of technology to support learning by a diverse student body.","PeriodicalId":175579,"journal":{"name":"2009 GSW Proceedings","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116636948","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Attarzadeh, Aditya Gupta","doi":"10.18260/1-2-620-38687","DOIUrl":"https://doi.org/10.18260/1-2-620-38687","url":null,"abstract":"This paper describes the results of a research project completed in Spring 2008 and shows details of a healthcare system along with future enhancements of the Automatic Wi-Fi Monitoring and Flushing System (A.Wi.M.F.S). The purpose of the research was to provide bedridden patients with an automatic collection pan to promote more privacy while eliminating the need for medical personnel to lift patients. In hospitals, the current bedpan [1] is a toileting facility that uses metal or plastic for urinal and fecal discharge. The present system requires an attendant to lift the patient and position the bedpan beneath the bedridden patient to collect excrement. This can cause injuries to the caregivers or the patients [2]. From this emerged the idea of the automatic bedpan which can reduce the risk of injury. The A.Wi.M.F.S has been designed to alleviate the physical strength needed for lifting patients. The Automatic Wi-Fi Monitoring and Flushing System contain a self-cleaning system that can be operated upon user’s request. The automatic flushing system can be implemented in already existing patient rooms by tapping into water supply and sewage lines with a built-in waste management system. The main purpose of the system is to provide patients with a system that is easy to use and is comfortable. The A.Wi.M.F.S is currently under review by the office of Intellectual Property Management at the University of Houston for a potential patent.","PeriodicalId":175579,"journal":{"name":"2009 GSW Proceedings","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129645326","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, when biological concepts are conveyed to chemical engineering students in a traditional manner, the students often end up lacking the ability to translate these ideas to engineering applications. This discrepancy arises in part from the different way in which engineering students think and approach problems relative to their natural science colleagues. Due to this, the chemical engineering department of Texas A&M has introduced a new course in biology which emphasizes student ability to apply biological concepts to solving engineering problems. Results from survey evaluation of student ability to apply learned biotechnology concepts to new problems indicates that the application oriented approach to teaching biotechnology concepts is effective and should be further developed.","PeriodicalId":175579,"journal":{"name":"2009 GSW Proceedings","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122977687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"The Researcher Incubator: Fast-Tracking Undergraduate Engineering Students into Research via Just-in-Time Learning","authors":"M. Traum, S. Karackattu","doi":"10.18260/1-2-620-38642","DOIUrl":"https://doi.org/10.18260/1-2-620-38642","url":null,"abstract":"An “incubator” in the research context is a place where the formation and development of new skills and ideas is encouraged, while the resulting new discoveries are spun out for further external development. To meet the need for trained researchers in the new Mechanical and Energy Engineering (MEE) Department at the University of North Texas (UNT), the faculty and undergraduates collaborated to develop a “Researcher Incubator” to integrate research experiences into the undergraduate engineering curriculum. This group’s missions are 1) to train UNT engineering undergraduates in the essentials of engineering research, 2) offer a pragmatic educational experience reflective of the skills necessary for engineers in the 21 century, and 3) fast-track undergraduates into successful research experiences much earlier than would be possible within conventional engineering programs. To eliminate barriers to entry for undergraduates, the Researcher Incubator uses “just-in-time” learning, a subset of inductive learning, which is modeled after manufacturing processes that deliver products to customers simultaneously with the moment of purchase. The hallmark of just-in-time learning in the context of research is that students are empowered to select and learn the specific elements necessary to solve a problem at the moment that a need for a solution arises. This approach is critical because it frees faculty advisors from being central repositories of knowledge and experience, eliminating a major bottleneck to progress by redistributing this responsibility to undergraduate researchers. The hypothesis of our just-in-time learning experiment is that if undergraduate students are 1) taught the skills needed to discover technical information and knowledge themselves, 2) enabled to work in collaborative groups that facilitate idea exchange, and 3) vested with responsibility to manage and execute serious research projects, they will spontaneously find or develop the theoretical and practical engineering knowledge required to successfully complete a project. In this paper, we outline the approach used at UNT to formalize, package, and teach just-in-time learning methods to undergraduate students through the Researcher Incubator. To highlight the validity of our hypothesis, we compared the research performance of undergraduates to that of graduate students over a 14-month period. Two metrics commonly used to gauge faculty success at engineering research universities were applied in this comparison: 1) the number of technical papers presented in a public forum or journal and 2) the dollar value of research","PeriodicalId":175579,"journal":{"name":"2009 GSW Proceedings","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125249149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

McClain","doi":"10.18260/1-2-620-38662","DOIUrl":"https://doi.org/10.18260/1-2-620-38662","url":null,"abstract":"Gold deposited Mylar film is commonly used to establish a constant heat flux convective boundary condition for wind-tunnel test surfaces. To minimize conduction through the test plate and promote a constant flux boundary, the accepted technique for mounting Mylar film to a surface is to apply the film oriented as gold-side up. However, the accepted mounting technique causes problems if the films are used to explore convective heat transfer from surfaces with high thermal conductivity protuberances and surface roughness. If high thermal conductivity elements are attached to the side with the gold layer, the local resistance of the film is lowered and hotspots with local increases in heat generation are created. To overcome the problems with roughness-element attachment, a new technique for mounting gold-deposition Mylar film in a gold-side down orientation was developed. This new application technique allows for the roughness elements to be mounted to the plastic side of the film while ensuring that the heat generation from the gold-deposition side is not disrupted. However, with this inverted mounting orientation, conduction into the test plate and conduction through the Mylar film must be considered when determining local convection coefficients. To validate measurements of convection coefficients made using the Mylar film and the new application technique, a series of test measurements has been performed using spherical segment roughness elements applied to a heated vertical test plate in natural convection. The temperature distributions of both sides of the test plate were measured using an infrared camera. The resulting unperturbed convection coefficients and the protuberance fin efficiencies are in general agreement with classical correlations for the test situations.","PeriodicalId":175579,"journal":{"name":"2009 GSW Proceedings","volume":"282 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116087881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One aspect of this project involves the development of Interlinked Curriculum Components (ICCs). These are web-based learning sites that aim to strengthen student knowledge in the fundamental subjects that span all chemical engineering courses, and to broaden their exposure to emerging technologies and non-traditional applications. This paper describes the development of an ICC that is focused on microprocess technology. This is a key emerging technology in chemical engineering that has applications ranging from discovery research of new catalysts and materials to small-scale manufacturing of high value-added products, toxic reagents, explosives, and other chemicals where point-of-use is preferred over a large-scale centralized manufacturing plant. The ICC module design follows a standardized protocol that includes five major sub-components: pre-testing quantitatively assess existing student knowledge on the module topic; (2) a set of topic notes so that students can perform a self-paced on-line review of the required subject matter; (3) examples that provide illustrations of various problems; (4) a series of exercises and problems having increasing complexity that allow the effect of various model equation set-ups and the effect of various model parameters to be studied in a conversational type of mode with graphical output; and (5) post-testing for quantitative assessment of student knowledge progression for validation of the desired modules outcomes.

The drop test has become a key qualification test for portable electronic products in recent years. However, actual drop test is very expensive and time-consuming. It requires much manpower in measurement and failure analysis. An alternative approach is to develop analytical dynamic models and to perform numerical simulations. The drop impact test can be simplified as a single degree of freedom dynamic system. The project of modeling and simulation for the drop impact test is assigned in the class.

This program, Communication across the Curriculum (CxC), created three central initiatives: Communication Studios, Communication-Intensive Courses, and the Distinguished Communicator award. To address the ABET requirements for communication and teamwork, the College of Engineering, in cooperation with CxC, opened the Engineering Communication Studio, which provides state-of-the-art technology, a physical space conducive to teamwork, and communication instruction from three full-time staff members. The Studio resources include a 3D scanner, a rapid prototype modeler, a large-format printer, and a range of engineering and communication software packages. The Studio also features fourteen computer workstations; a Wi-Fi hotspot lounge; a conference room with teleconferencing capabilities, a wall-mounted video capture system, and a SMART Board™; and, finally, a wide range of audio-visual equipment and technical references in the Studio lending inventory. On the curricular level, the staff works with faculty to integrate communication assignments within existing courses in order to incorporate communication skills without detracting from traditional content. These courses are identified as Communication-Intensive in the University Course Offerings Booklet, and then become a critical component of the Distinguished Communicator award. A second component of this award requires students to build a digital portfolio that showcases their communication skills. As the students progress in their engineering curricula, the Studio provides a vital support system to improve the requisite communication skills to succeed as engineering professionals.","PeriodicalId":175579,"journal":{"name":"2009 GSW Proceedings","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127557762","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
