After the pilot test, students’ average grade in the treatment group wasslightly (but not significantly) better than the control group on the post test. Students’ survey andinterview data indicated positive feedback about OpenDSA, with the average response on howwell they liked using the OpenDSA materials increasing after use as compared to a similar pre-test question about whether they would like to use such materials.1.

partnerships with peer departments and institutions.1 IntroductionInternational partnerships are frequently proposed, but many never make it beyond anexpression of mutual interest. The challenges to overcome are initiating first contact, discussingresearch areas to determine if there are overlapping areas or topics of mutual interest, seekingout and pursuing visiting and funding opportunities, and loss of initial momentum.To overcome these challenges, we have developed a process for building and strengtheninginternational partnerships in computing and information technology.2 Our Approach Page 23.567.2Our approach consists of three primary stages

In these algorithms both mesh and tree connections of processors were exploited.1-IntroductionParallel computing for image processing has recently received considerable attentions 1,3,10,13.Technological advances have made the design of fine-grain architectures possible and many practicalalgorithms have been implemented. Line detection by the Hough Transform 1 method is a powerfultool in shape analysis. It extracts global features from images; however, because of its computationalcomplexity, it is not easily implemented in real-time for some applications. One approach

Therefore the system had to be designed so that the cost, multiplied by 15, was reasonable. Even with 15 stations students work in pairs, and two or three lab sections are required.Measurement of effectiveness of the student experienceIn line with the research goals of the lab experience measurements will be made of: 1. Students’ understanding of CPS 2. Students’ understanding of the pillars of IT relevant to this experience. 3. Students’ evaluation (opinion) of the relationship between CPS and IT.These

In purely virtual environments, most(if not all) aspects of the user experience are synthesized. However, because virtual objects areembedded within the physical world, AR lies between these two extremes. Its strong ties to thephysical world naturally

Audiology technicians generally will make the decision based on theaudiogram results and a consultation with the patient and the decision to be made at that point isgenerally pretty clear. However, there are occasions where the data leaves them in a spot wherethey can go either way. In these cases, they might “benefit from a second opinion given by anautomatic system with an explanation of how that second opinion was arrived at”1.

Even with theseincreasing demands, there is a severe lack of representation of minority women in the field.Participation of women in computing and information technology, although never equitable, hasdeclined during the past decade (Misa, 2010)1.
