Research indicates computer science students are not developing the teamwork and communication skills essential for success in computer science careers and academic programs often lack effective tools to address these concepts. Collaboratory is a bag-building board game that develops team coordination skills among computer science students by emphasizing strategy and cooperation in the context of an accessible, engaging, and systemically sophisticated social game experience. Similar in scope and style to popular games like Settlers of Catan, Ticket to Ride, or Carcassonne, Collaborate emphasizes strategy and cooperation while minimizing luck and conflict to create a deep, authored play experience that abstracts the major elements of working in a collaborative software development setting into play sessions that are typically 30 to 45 minutes in length. Players work together to complete projects that require them to review and discuss development concepts such as backend technology, user interface design, and quality assurance processes, while making strategic choices about how to deploy resources, manage risk, and adjust to changes. Collaborate is intended for use by high school and college level CS students in class or independent study environments with content aligned to state computer science standards and informed by professional best practices.
