    Clearn: A Cost-conscious Student-led Online Judge for a Large Programming Course
    (2024) Herskovic Maida, Valeria Paz; Muñoz Gama, Jorge; Balladares Conejeros, Fernando Ignacio; Quiroz Pastor, Nicolas Alberto; Flores, Pablo
    Online judges in programming courses allow students to improve their coding abilities and instructors to analyze student work and detect challenging topics. Although several online judge platforms are available, most are limited in that they cannot support a large number of students simultaneously working on an assignment during a fixed time period, or can only do so at a significant cost, making the use of such systems in developing countries non-viable. This paper presents Clearn, a new platform that is (1) cost-conscious, as we have focused on lowering costs, (2) student-led, as we have empowered students and teaching assistants to lead its development and maintenance, and (3) highly simultaneous, as it allows over 1,000 students to work simultaneously on a timed assignment. This paper presents the platform, as well as the lessons learned during its development and deployment, and its reception by the students.

    Cluster and trajectory analysis of motivation in an emergency remote programming course
    (2024) Jahr Andrade, Andrés Sebastián; Meza Ledezma, Javiera Francisca; Munoz-Gama, Jorge; Herskovic, Luis; Herskovic Maida, Valeria Paz
    Emergency remote teaching is a temporary change in the way education occurs, whereby an educational system unexpectedly becomes entirely remote. This article analyzes the motivation of students undertaking a university course over one semester of emergency remote teaching in the context of the COVID-19 pandemic. University students undertaking a programming course were surveyed three times during one semester, about motivation and COVID concern. This work explores which student motivation profiles existed, how motivation evolved, and whether concern about the pandemic was a factor affecting motivation throughout the course. The most adaptive profile was highly motivated, more prepared and less frustrated by the conditions of the course. However, this cluster experienced the highest levels of COVID-19 concern. The least adaptive cluster behaved as a mirror image of the most adaptive cluster. Clear differences were found between the clusters that showed the most and least concern about COVID-19

    Modeling interactions in human-centric wireless sensor networks
    (IEEE, 2014) Monares, Älvaro; Ochoa, Sergio; Herskovic Maida, Valeria Paz; Santos, Rodrigo; Pino, José
    The recent growth of social networking and sensing applications has enabled people to perform crowd computing. In turn, this activity has opened several opportunities to address people's needs in various application areas, such as tourism, security, entertainment and emergency response. However, the design of these applications has also brought several challenges to software designers. Since users of these systems interact among them in heterogeneous physical scenarios, their interactions should be formally considered in the design of these applications in order to determine whether or not the services embedded in the system are suitable to support those interactions. The lack of guidelines to address this modeling issue not only jeopardizes the suitability of these applications, but also implies the services provided by the system can be evaluated only after implementation, which is clearly risky and expensive. This article proposes an initial modeling language that allows software designers to address this challenge through the representation of the interaction among users of a system. The interaction model represented using the proposed language allows designers to evaluate, at the design time, the information flow and the availability of interaction supporting services in the system. The usability and usefulness of the proposal are shown using a running example.

    Some observations from the analysis of an online discussion board
    (IEEE, 2012) Ochoa, Sergio; Pino, José; Baloian, Nelson; Antunes, Pedro; Herskovic Maida, Valeria Paz
    Many educators and educational institutions include an online discussion forum in the content management system supporting their courses, because they think such tool facilitates the instructional process. It could be true if we explicitly design the instructional process to take advantage of this tool, but to do so we have to better understand how users actually use online discussion boards. Trying to answer such a question this paper presents a study of discussions occurring in several undergraduate courses in computer science offered by the University of Chile. More specifically, the study was based on the semantic analysis of a representative set of messages registered in eight different courses occurring in a period of two years. The obtained results indicate that the users do not perceive the forum as a learning tool, but as a communication platform that allows them to socialize and address coordination and operative issues related with the courses.

    The impact of technology use for care by informal female caregivers on their well-being: a scoping review protocol
    (2023) Inostroza Correa, María Alejandra; Aparicio Alonso, Andrés David; Miranda Herrera, Paula Andrea; Salinas Suárez, Carolina Inés; Herskovic Maida, Valeria Paz; Chackiel Durán, Camila Valentina
    Objective: The objective of this scoping review is to assess the extent of literature examining the impact of technology use by informal female caregivers in their quality of life to characterize existing research gaps and to identify what evidence is already available. Introduction: The well-being of caregivers has become a prominent topic in recent studies on caregiving, especially for informal caregivers, who are mostly female. Within this context, the use of technologies to assist in caregiving tasks has become increasingly popular and some evidence about their impact on caregiver well-being is available. However, significant research gaps persist.Inclusion criteria: We are interested in studies exploring how informal female caregivers use technology and how such use impacts their well-being.Methods: We will search Web of Science and Scopus for studies in English, Spanish and Portuguese published in peer-reviewed journals since from 2018. Sources will be screened in stages by two independent reviewers; data will be extracted from selected full texts and results will be integrated into a narrative summary supported by tables and diagrams following the research questions.

    Understanding presence awareness information needs among engineering students
    (IEEE, 2012) Herskovic Maida, Valeria Paz; Neyem, Hugo Andrés; Ochoa, Sergio F.; Pino, José A.; Antunes, Pedro
    The flexibility and changing nature of loosely coupled work makes presence awareness crucial to promote interactions among collaborators. Undergraduate students, in their efforts to accomplish coursework-related tasks, must deal with having several available channels to interact with others, accessing and sharing educational material, and the need to optimize their time. Most of them work in a loosely coupled way as the main strategy to reduce the effort spent in the educational process. Presence awareness may help them achieve interactions among potential collaborators in this scenario. This paper aims to identify the most suitable presence awareness information to promote on-demand interactions among college students. A study was conducted for this purpose, involving undergraduate engineering students from two universities in Chile. This article also presents a classification of presence awareness mechanisms for loosely-coupled mobile group work.
