A systematic mapping study of bug reproduction and localization
(Elsevier BV, 2024) Wang , Di; Galster, Matthias; Morales-Trujillo , Miguel
Context: Identifying the root cause of a software bug and fixing it is challenging. One reason for this is that many bugs are not reproducible during bug fixing. Objective: We aim to provide an overview of existing works on bug reproduction and localization. We ask four research questions: RQ1: What types of problems have been studied in the area of bug reproduction and localization? RQ2: How are problems studied in previous research? RQ3: What are the main findings and outcomes of previous studies? RQ4: What are the gaps and challenges identified in previous studies? Method: We conducted a systematic mapping study analyzing research literature published between 2011 and 2021. The search for primary studies involved four major computer science digital libraries and resulted in 134 studies for analysis. Results: Regarding RQ1 we found that many studies focus on information retrieval-based approaches to support bug reproduction and localization. Regarding RQ2 we found that bug reports and source code are the typical data sources of bug reproduction and localization. Also, most studies include experiments with historical data but do not investigate ongoing projects. Regarding RQ3 we found that many studies adapt or combine existing approaches for bug reproduction and localization to improve their accuracy or applicability (e.g., combine requirements-related information and bug reports to increase information-retrieval-based techniques). Regarding RQ4 we found that existing solutions for bug reproduction and localization have rarely been integrated into the workflow of developers. Conclusion: Although bug reproduction and localization have been studied in quite some detail, new challenges and gaps emerge due to the evolution of software technologies and practices and the practical needs of software developers. For example, bug reproduction approaches for traditional web applications do not work well with modern “Single Page Web Applications” (SPA) and related technologies, e.g., Angular or React.

Augmented Reality in Learning Settings: A Systematic Analysis of its Benefits and Avenues for Future Studies
(2024) Mohammadhossein N; Richter A; Lukosch, Stephan
Despite its increasing use in various settings, Augmented Reality (AR) technology is still often considered experimental, partly due to a lack of clear understanding of the benefits of using AR. This study systematically reviews research on the use of AR in learning settings. Our analysis of 93 relevant articles offers 21 benefits related to the learning gains and outcomes of using AR. Our study shows that the positive effects of using AR on learners’ motivation and joy have been well-studied, whereas the effects on independent learning, concentration, spontaneous learning, critical thinking, and practical skills have not yet been examined in detail. Beyond classifying and discussing the benefits of using AR in learning settings, we elaborate avenues for future studies. We specifically point to the importance of conducting long-term studies to determine the value of using AR in learning beyond the initial novelty and exploring the integration of AR with other technologies.
