End-user programmers face many barriers in programming. Research has seen many programming environments that attempted to lower or remove the barriers but despite these efforts, empirical studies continue to report barriers users face. To investigate this issue, we took a theory-informed approach. Using theories from design, creativity, and problem solving...
This paper reports on an empirical study involving end users that addresses the question of whether it is possible to provide the benefits of formal testing within the informal spreadsheet paradigm. We have developed a "What You See Is What You Test" (WYSIWYT) methodology that brings the benefits of formal...
Traditionally, research into end-user programming has focused on how to make programming more accessible to end users conducting the programming activities all by themselves. However, few researchers have considered introducing the concept of collaborative programming into the area of end-user programming, and how the programming environments and devices should be...
End users' programs are fraught with errors, costing companies millions of dollars. One reason may be that researchers and tool designers have not yet focused on end-user debugging strategies. To investigate this possibility, this dissertation presents eight empirical studies and a new strategy-based end-user debugging tool for Excel, called StratCel....
