Much research shows that the learning process is highly enhanced when this kind of approach is used in computer science teaching, not only because of the motivation they engender, but also because high end results can be easily generated with relatively little effort.

The program, Students in Programming, Robotics, and Computer Science (SPARCS), can adapt to different presentation environments, such as independent after school sessions or a semester-long apprenticeship program. We trace one implementation of the program through the initial deployment, the development of infrastructure, and a reorganization of content to address student interests. We found that student attrition dropped and the average session enjoyment increased when our sessions integrated consumer technologies such as mobile applications, video games, and the Minecraft computer game. In this paper, we provide readers a framework for running computing outreach activities around similar consumer technologies.

These molecules can coordinate to two divalent metal ions in the RNase H active site. Inhibition of enzymatic activity was measured in a biochemical assay, but no antiviral effect was observed. Binding was demonstrated via a solid state structure of the isolated p15-Ec domain of HIV-1 RT showing inhibitor and two Mn(II) ions bound to the RNase H active site.

Moreover, in the current interaction model for immersive environments, based on wands and 3D mice, a change of context is necessary in order to execute non-immersive tasks. These constant context changes from immersive to 2D desktops introduce a rupture in user interaction with the application. The objective of ...

This volume is a good picture of what is EDCC: a well-established conference that brings together Dependability researchers throughout Europe (but not only). The volume also shows the complexity and diversity of an area that brings together academia and industry, covers hardware and software, and spans most computer science ...

Research paper thumbnail of Interaction Networks: Generating High Level Hints Based on Network Community Clustering

We show how using network community detecting techniques are used to identify subgoals in problems in a logic tutor. We then use those community structures to generate high level hints between subgoals. The preliminary results show that using network analysis techniques are promising for exploring and understanding user data from open problem solving environments.

In particular, different courses have different levels of technical depth. The "Beauty and Joy of Computing" curriculum, used by two of the initial five pilot sites, aims high, with recursion and higher order functions included in the programming half of the course. This session is for high school or college level instructors considering teaching an AP CS Principles course and interested in using the BJC curriculum, and/or the Snap! (formerly BYOB) visual programming language used in the curriculum. See http://bjc.berkeley.edu for the curriculum and http://snap.berkeley.edu for the language.
