As percentages of women in computing jobs and university programs decline, recruiting and retaining women in the field of Computer Science (CS) becomes increasingly important. Undergraduate CS programs, and more specifically, introductory-level CS courses, offer an opportunity to introduce women to CS studies. Furthermore, learning experiences in introductory CS courses can be pivotal in shaping female students' perceptions of CS. Collaborative learning, in various forms, is an instructional construct that has been shown to be effective in recruiting and retaining women in undergraduate CS programs. In this paper we present an exploratory study on formal learning groups and their potential to attract and maintain female students' interest in CS studies.

Prior research indicates that today's students, especially women, are attracted to careers in which they recognize the direct benefit of the field for serving societal needs. Traditional college level computer science courses rarely illustrate the potential benefits of computer science to the broader community. This paper describes a curricula development effort designed to embed humanitarian projects into undergraduate computer science courses. The impact of this program was measured through student self-report instruments. Through this investigation, it was found that students generally preferred projects that they perceived as "fun" over the projects that were social in nature. This may, in part, be due to the fact that it was difficult to reduce socially relevant problems to a level that beginning students could easily comprehend. This made it difficult to capitalize on the appeal of socially relevant problems in the early computer science courses.

We present a software infrastructure that embeds physical hosts in a simulated network. Aiming to create a large-scale real-time virtual network testbed, our real-time interactive simulation approach combines the advantages of both simulation and emulation, by maintaining flexibility of the simulation models and increasing fidelity as real systems are included in the simulation. In our approach, real-world distributed applications and network services can run together with the real-time simulator; real packets are injected into the simulation and subject to the simulated network conditions computed as a result of both real and virtual traffic competing for network resources. A prototype of the proposed emulation infrastructure has been implemented based on virtual private network (VPN). One distinct advantage of our approach is that it does not require special hardware. Furthermore, it is flexible, secure, and scalable-attributes inherited directly from the VPN implementation. We conducted a set of preliminary experiments to assess the performance limitations of our emulation infrastructure. We also present an interesting case study to demonstrate the capability of our approach.
