- Computing learners may not master basic concepts, or forget them between courses or from infrequent use. Learners also often struggle with advanced computing courses, perhaps from weakness with prerequisite concepts. One underlying challenge for researchers and instructors is determining the reason why a learner gets an advanced question wrong. Was the wrong answer because the learner lacked prerequisite skills, has not mastered the advanced skill, or some combination of the two? We contribute a design investigation into how to create differentiated questions which diagnose prerequisite and advanced skills at the same time. We focused on tracing and related skills as prerequisites, and on advanced object-oriented programming, concurrency, algorithm and data structures as the advanced skills. We conducted an inductive qualitative analysis of existing assessment questions from instructors and from a concept inventory with a validity argument (the Basic Data Structures Inventory). We found dependencies on a variety of prerequisite knowledge and mixed potential for diagnosing difficulties with prerequisites. Inspired by this analysis, we developed examples of differentiated assessments and reflected on design principles for creating/modifying assessments to better assess both advanced and prerequisite skills. Our example differentiated assessment questions and methods help enable research into how prerequisites skills affect learning of advanced concepts. They also may help instructors better understand and help learners with varying prerequisite knowledge, which may improve equity of learning outcomes. Our work also raises theoretical questions about what assessments really assess and how separate advanced topics and prerequisite skills are.

Panel : Synergistic Perspectives on Collaborative Learning with Version Control Tools

- Version control systems are widely used in industry and form a staple of modern software development, and this panel addresses the benefits and difficulties of introducing version control in education. Version control systems such as Git, and software development platforms such as GitHub, Bitbucket and GitLab are industry standards for which there is an increasing appeal within education. In general, students and teachers are motivated to use these tools in the classroom to increase graduates' competitiveness in the job market. Although highly desirable, the adoption of version control is hindered by a steep learning curve for both teachers and students, a lack of resources tailored to specific instructional and learning needs, as well as inadequate integration and alignment with the learning outcomes in the program curricula. The panel will analyze these challenges, solicit feedback from the audience's experience with version control tools, and facilitate discussions around promising strategies that could benefit student learning and graduates' professional competencies expected in the workplace.
