• Abstract: Static analysis tools are frequently used to scan the source code and detect deviations from the project coding guidelines. Given their importance, linters are often introduced to classrooms to educate students on how to detect and potentially avoid these code anti-patterns. However, little is known about their effectiveness in raising students awareness, given that these linters tend to generate a large number of false positives. To increase the awareness of potential coding issues that violate coding standards, in this paper, we aim to reflect on our experience with teaching the use of static analysis for the purpose of evaluating its effectiveness in helping students with respect to improving software quality. This paper discusses the results of an experiment in the classroom over a period of 3 academic semesters, involving 65 submissions that carried out code review activity of 690 rules using PMD. The results of the quantitative and qualitative analysis shows that the presence of a set of PMD quality issues influence the acceptance or rejection of the issues, design, and best practices-related categories that take a longer time to be resolved, and students acknowledge the potential of using static analysis tools during code review. Through this experiment, code review can turn into a vital part of the educational computing plan. We envision our findings enabling educators to support students with code review strategies to raise students awareness about static analysis tools and scaffolding their coding skills.

  This systematic literature review identifies existing instructional approaches, their objectives, and the strategies used for measuring their effectiveness. We classified these studies into three categories: (1) studies focused on developing or evaluating automated tools and their usage, (2) studies discussing other instructional materials, and (3) studies discussing how to integrate code structure into the curriculum through a holistic approach to course design to support code quality.

  In large programming classes, it takes a significant effort from teachers to evaluate exercises and provide detailed feedback. In systems, test cases are not sufficient to assess exercises, since detailed programming and resource management bugs are difficult to reproduce. This paper presents an experience report on static analysis for the automatic evaluation of systems programming exercises.

  This paper proposes a new approach to automatically identify which change in the code caused a test to fail. The method leverages Large Language Models (LLMs) to associate error messages with the corresponding code changes causing the failure. Our approach reaches an accuracy of 71% in our newly created dataset, which comprises issues reported by developers at EA over a period of one year.

  We use Language Models (LMs) as educational experts to assess the impact of various instructions on learning outcomes. We introduce an instruction optimization approach in which one LM generates instructional materials using the judgments of another LM as a reward function. Human teachers' evaluations of these LM-generated worksheets show a significant alignment between the LM judgments and human teacher preferences.

  This paper studies the answers to the standardized university evaluation questionnaires of foundational computer science courses which recently introduced autograding. We hypothesize how the autograder might have contributed to the significant changes in the data, such as, improved interactions between tutors and students, improved overall course quality, improved learning success, increased time spent, and reduced difficulty. The autograder technology can be validated as a teaching method to improve student satisfaction with programming courses.
