Peer review is the standard process within academia for maintaining publication quality, but it is also widely employed in other settings, such as education and industry, for improving work quality and for generating actionable feedback to content authors. For example, in the software industry peer review of program source code—or peer code review—is a key technique for detecting bugs and maintaining coding standards. In a programming education context, although peer code review offers potential benefits to both code reviewers and code authors, individuals are typically less experienced, which presents a number of challenges. Some of these challenges are similar to those reported in the educational literature on peer review in other academic disciplines, but reviewing code presents unique difficulties. Better understanding these challenges and the conditions under which code review can be taught and implemented successfully in computer science courses is of value to the computing education community. In this work, we conduct a systematic review of the literature on peer code review in higher education to examine instructor motivations for conducting peer code review activities, how such activities have been implemented in practice, and the primary benefits and difficulties that have been reported. We initially identified 187 potential studies and analyzed 51 empirical studies pertinent to our goals. We report the most commonly cited benefits (e.g., the development of programming-related skills) and barriers (e.g., low student engagement), and we identify a wide variety of tools that have been used to facilitate the peer code review process. While we argue that more empirical work is needed to validate currently reported results related to learning outcomes, there is also a clear need to address the challenges around student motivation, which we believe could be an important avenue for future research.
Abstract-Indonesia is a country located on top of some tectonic plates that bring potential natural disasters. Disaster management system is considered essential in controlling the situation in the site both before and after the disaster takes place. In disaster situation, the government and society are involved in a volunteer team in order to help minimize victims and support survivors. However, the volunteering activities are often hindered since there are problems in the disaster site. One of the problems is late responses due to poor coordination among volunteers that drives the delay in disaster relief. Therefore, it is necessary to have an application that maps the positions of volunteers in a disaster site, so that the disaster management coordinator can disseminate volunteers to disaster areas based on needs. The purpose of the study is to propose an application called 'MyMapVolunteers' that effectively and efficiently detects the position of the volunteers in order to improve disaster management service. In this case, real time and location based service technology will able to detect the position of each volunteer. 'MyMapVolunteers' is composed of two platforms, which are mobile and web applications. Mobile platform is an application that uses GPS function provided by the smartphone to find the volunteers' location coordinates and then send the data of the location automatically and manually. The web platform is used to receive volunteers' location data and to present them in google map, therefore disaster management coordinator can monitor the positions of and search for volunteers faster.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
