It's really hard to design products by focus groups. A lot of times, people don't know what they want until you show it to them.

Programming has recently become more common among ordinary end users of computer systems. We believe that these end-user programmers are not just coders but also designers, in that they interlace making design decisions with coding rather than treating them as two separate phases. To better understand and provide support for the programming and design needs of end users, we propose a design theory-based approach to look at end-user programming. Toward this end, we conducted a think-aloud study with ten end users creating a web mashup. By analyzing users' verbal and behavioral data using Schön's reflection-in-action design model and the notion of ideations from creativity literature, we discovered insights into end-user programmers' problem-solving attempts, successes, and obstacles, with accompanying implications for the design of end-user programming environments for mashups. The contribution of our work is three-fold: 1) the methodology of using a design lens to view programming, 2) evidence, through insights gained, of the usefulness of this approach, and 3) the implications themselves.

Can we learn about users' problem-solving strategies by observing their actions? This article introduces a data mining system that extracts complex behavioral patterns from logged user actions to discover users' high-level strategies. Our application domain is an HCI study aimed at revealing users' strategies in an end-user debugging task and understanding how the strategies relate to gender and to success. We cast this problem as a sequential pattern discovery problem, where user strategies are manifested as sequential behavior patterns. Problematically, we found that the patterns discovered by standard data mining algorithms were difficult to interpret and provided limited information about high-level strategies. To help interpret the patterns as strategies, we examined multiple ways of clustering the patterns into meaningful groups. This collectively led to interesting findings about users' behavior in terms of both gender differences and debugging success. These common behavioral patterns were novel HCI findings about differences in males' and females' behavior with software, and were verified by a parallel study with an independent data set on strategies. As a research endeavor into the interpretability issues faced by data mining techniques, our work also highlights important research directions for making data mining more accessible to non-data-mining experts.

Little is known about the strategies end-user programmers use in debugging their programs, and even less is known about gender differences that may exist in these strategies. Without this type of information, designers of end-user programming systems cannot know the "target" at which to aim, if they are to support male and female end-user programmers. We present a study investigating this issue. We asked end-user programmers to debug spreadsheets and to describe their debugging strategies. Using mixed methods, we analyzed their strategies and looked for relationships among participants' strategy choices, gender, and debugging success. Our results indicate that males and females debug in quite different ways, that opportunities for improving support for end-user debugging strategies for both genders are abundant, and that tools currently available to end-user debuggers may be especially deficient in supporting debugging strategies used by females.
