Success in the computing industry often depends on an individual's ability to be a productive member of an effective study group or project team. In order to prepare students for successful careers, computer science curriculum often includes group projects. This paper discusses the challenges of forming effective student groups, discusses existing software for forming groups, and introduces groupformation.org, a new free and open source group formation service.

Building a compiler for a domain specific language (a language designed for a specific problem domain) can engage students more than traditional compiler course projects. Most students feel that compiler courses are irrelevant because they are not likely to get a job writing compilers[2]. However, the technologies used to construct a compiler are widely applicable [2,5]. Using a domain specific language demonstrates to students the wide applicability of compiler construction techniques. This paper presents the results of using a domain specific language in an upper division compiler course.

This paper presents a novel methodology for viewing large graphs.The basic concept is to allow the user to interactively navigate through large graphs learning about them in appropriately small and concise pieces.An architecture is present to support graph exploration.It contains methods for building custom layout algorithms hierarchically, interactively decomposing large graphs, and creating interactive parameterized layout algorithms.As a proof of concept, examples are drawn from a working prototype that incorporates this methodology.

Background: Direct manipulation interfaces, such as the Macintosh desktop, often represent objects with icons [l, 41. For example, text files are represented by icons. Selection of the icon invokes an editor to view the file it represents, thus the icon not only represents the text file but also represents a text editor used to view the text file. Each type of object is viewed by using a specific program. Diagram objects, for example, require a graphical editor to view. In a typical iconic interface, icons represent a single view of an object. While the single-view single-icon model has proven very intuitive and easy to use, some objects have more than one logical view [2]. Program code can be viewed as text by using a text editor, or it can be viewed as program code by a compiler. The machine code that corresponds to the program code can be thought of as another view, thus the execution of a program can be thought of as another view of program code. This paper describes a mechanism for grouping a set of icons that depict several views of a single object into one multidimensional icon. Multidimensional icons group sets of icons, each describing a unique view of an object, into a single entity. The individual icons are projected onto the sides of a simulated cube. There are two distinct advantages to using a cube instead of displaying all the icons in a menu. The first advantage is that since cubes are very familiar objects, it is a natural mental model to think of the faces of a cube as views of the entire cube—views of the actual object. The second advantage is that by allowing rotation of the cube, several icons representing views of an object are accessible using only a fraction of the screen space required to display all the icons.

An active data model is one that not only stores data, but also acts upon changes to the data in ways that reflect application domain semantics. This paper introduces an active object-oriented model based on incremental attribute evaluation (one-way constraints) and discusses how it can be used to support a number of tasks in a User Interface Management System. It is shown how this model can provide unified support for lexical, syntactic, and semantic feedback, how the model supports the specification and implementation of dynamically changing graphical layouts, and how the model can be used as the basis for support of user extensible interfaces.
