A previous report identified several usability and learnability problems with integrated development environments (IDE) for Java. That report also cast these problems as examples of a conceptual gap between developer mental models and how programs are represented in IDEs. This present study extends the previous work through heuristic and psychometric assessment of problems reported by both experienced and inexperienced developers in their use of an IDE for C++. The results indicate that both groups identified similar kinds of ease-of-use problems, especially concerning program learnability and visibility (e.g., the usefulness of error and help messages). These findings are discussed in relation to other research results about developers' experiences with CASE tools and conceptual gaps between the tools and their users.

The design of structured objects is frequently accomplished with the use of CAD systems, some of which allow for parametrised designs, which represent families of objects. Some existing CAD systems permit parametrisation by providing interfaces to programming languages, leading to a sharp division between the visual and programming aspects of building complex designs. In previous work, a design language LSD was proposed, which used visual logic programming to overcome this separation and provides "assembly semantics" for building an instance of a parametrised design corresponding to specific parameter values. Also of interest to designers, however, is the behaviour of the objects they design. For example, the point of building a mechanical device such as an internal combustion engine is to obtain a particular mechanical behaviour. Here we extend the formal model for solid objects on which LSD relies in order to support the definition of particular kinds of behaviours.

We conducted a one-day design workshop in which residents of a community collaborated in learning about and designing community-related visual simulations (to be implemented in Stagecast Creator). An analysis of their design ideas and concerns revealed several visual design patterns that were apparent even in these very early stages of simulation design. This analysis helps us to characterize the design constructs people may be able to specify or learn when first encountering visual simulation design tasks and projects. In this paper, we introduce the concept of patterns and their relationship to visual programming and present several visual programming language patterns mined from the projects developed at the community simulation design workshop. Finally, we discuss how these patterns might be incorporated into minimalist tutorials that we are developing to introduce community residents to visual simulation design.
