With real-time collaborative editing, multiple programmers can use Collabode to edit the same source code at the same time. Collabode introduces error-mediated integration, where multiple editors see the text of one another's changes while being isolated from errors and in-progress work, and error-free changes are integrated automatically. Three models of collaborative programming are presented and evaluated using Collabode. Classroom programming brings zero-setup web-based programming to computer science students working in a classroom or lab. Test-driven pair programming combines two existing software development strategies to create a model with clear roles and explicit tool support. And micro-outsourcing enables one programmer to easily request and integrate very small contributions from many distributed assistants, demonstrating how a system for highly-collaborative programming enables a development model infeasible with current tools. To show that highly-collaborative programming, using real-time collaborative editing of source code, is practical, useful, and enables new models of software development, this thesis presents a series of user studies. A study with pairs of both student and professional programmers shows that error-mediated integration allows them to work productively in parallel. In a semester-long deployment of Collabode, students in an MIT software engineering course used the system for classroom programming. In a lab study of a Collabode prototype, professional programmers used test-driven pair programming. Finally, a study involving both in-lab participants and contractors hired online demonstrated how micro-outsourcing allowed participants to approach programming in a new way, one enabled by collaborative editing, automatic error-mediated integration, and a web-based environment requiring no local setup.","abstract_html":"This thesis presents Collabode, a web-based integrated development environment for Java.
