- ItemCOGNITIVE STRATEGIES FOR MENTAL CALCULATION(CLAME-COMITE LATINOAMERICANO MAT EDUC, 2011) Galvez, Grecia; Cosmelli, Diego; Cubillos, Lino; Leger, Paul; Mena, Arturo; Tanter, Eric; Flores, Ximena; Luci, Gina; Montoya, Soledad; Soto Andrade, JorgeWe focus on the study of the variety of cognitive strategies, either idiosyncratic or learned, used by students in the first cycle of elementary education in Chile to practice activities of mental calculation. We present an analysis of performance in additive mental calculation tasks (addition and subtraction) of a sample of students from state-subsidized schools in middle and low-middle socioeconomic strata in the cities of Santiago and Valparaiso. We construct a catalogue of the strategies detected and a first version of a software developed by us and available in the internet, which enables us to assess the student's performance, including their response times. We also analyze the correlation between the performance in the proposed tasks (percentage of correct answers and response times) and the average school achievement in mathematics.

- ItemIntroduction to Special Issue on Visualization Applied to Software Engineering(2023) Leger, Paul; Bergel, Alexandre; Sandoval Alcocer, Juan Pablo; Merino, LeonelSoftware visualization is a broad research area whose general goal is to enhance and promote the theory, realization, and evaluation of approaches to visually encode and analyze software systems, including software development practices, evolution, structure, and software runtime behavior. Software visualization is inherently interdisciplinary, drawing on theories and techniques from information visualization and computer graphics and applying these in the software engineering domain. This special issue on software visualization aims to bring together a community of researchers from software engineering, information visualization, computer graphics, human-computer interaction, and data science to discuss theoretical foundations, algorithms, techniques, tools, and applications related to software visualization. The special issue received 17 submissions of which 6 were accepted for publication (i.e., acceptance rate of 35.3%). Amongst the accepted papers, three correspond to extended versions of papers published in the IEEE Working Conference on Software Visualization (VISSOFT) 2021.
