Bell, Brigham, Rieman, John and Lewis, Clayton H. (1991): Usability Testing of a Graphical Programming System: Things We Missed in a Programming Walkthrough. In: Robertson, Scott P., Olson, Gary M. and Olson, Judith S. (eds.) Proceedings of the ACM CHI 91 Human Factors in Computing Systems Conference April 28 - June 5, 1991, New Orleans, Louisiana. pp. 7-12.

“Traditional programming language design has focussed on efficiency and expressiveness, with minimal attention to the ease with which a programmer can translate task requirements into statements in the language, a characteristic we call "facility." The programming walkthrough is a method for assessing the facility of language design before implementation. We describe the method and its predictions for a graphical programming language, ChemTrains. These predictions are contrasted with protocols of subjects attempting to write their first ChemTrains program. We conclude that the walkthrough is a valuable aid at the design stage, but it is not infallible. Our results also suggest that it may not be enough for programmers to know how to solve a problem; they must also understand why the solution will succeed.”

Lewis, Clayton H., Reiman, John and Bell, Brigham (1991): Problem-Centered Design for Expressiveness and Facility in a Graphical Programming System. In Human-Computer Interaction, 6 (3) pp. 319-355.

“This article presents a case study in the use of problems in design. Problems -- concrete examples of user goals whose accomplishment a system is intended to support -- were used to describe the intended functions of a graphical programming system and to manage the growth of the space of design alternatives for the system. Problems were also used to evaluate alternative designs: They served as bench marks for comparing both the solutions offered by differing designs and the work required of users to reach these solutions. The problem-centered design process includes a representation of design rationale in which the strengths and weaknesses of design alternatives in dealing with specific problems, rather than abstract connections among design issues, are central.”

Smolensky, Paul, Bell, Brigham, Fox, Barbara, King, Roger and Lewis, Clayton H. (1987): Constraint-Based Hypertext for Argumentation. In: Weiss, Stephen and Schwartz, Mayer (eds.) Proceedings of ACM Hypertext 87 Conference November 13-15, 1987, Chapel Hill, North Carolina. pp. 215-245.

“In this paper we describe a hypertext system we are developing for the support of reasoned argumentation: the EUCLID project. We use the project to address two general problems arising with hypertext: the problems of controlling user/document interaction, and the problem of controlling the screen. We suggest that guiding users' interaction with hypertext is difficult because of the unique form of discourse that hypertext represents, and that structuring user/document interaction can be achieved through specializing to a particular type of material and designing the hypertext system to respect the particular discourse structure characteristic of that material. EUCLID's design is tuned to the structure of reasoned discourse. The problem of screen management in EUCLID is a serious one, because our presentation of complex arguments requires mapping the complex logical relations between parts of realistic arguments onto complex spatial relations between items in the display. We describe a general system we are developing which provides this high degree of control for hypertext screen management. This system represents a constraint-based approach to hypertext, in which the items from the underlying database that are to be displayed may each contribute a number of constraints on the layout; a general constraint-satisfier then computes a screen layout that simultaneously satisfies these constraints. Each time an item is to be added to or deleted from the screen, the constraint set is adjusted and the screen layout is recomputed; thus the spatial relationships on the screen provide at all times a veridical representation of the underlying relations between displayed database items. This kind of strong screen control is demanded by hypertext applications which, like ours, are fine grained: the number of nodes and links being displayed number in the hundreds.”
