Gamification has permeated education as a strategy to improve the teaching-learning process. Research shows that gamified reward systems based on badges, leaderboards, and avatars modifies the learning environment and student attitudes. This research aimed primarily to assess the change in attitude towards mathematics in high school students through a gamified methodology involving a reward system managed through a web platform called Gamit! This platform was developed by professors from two Latin American universities to manage gamification in a way that ensured that the anonymity of the class rankings was maintained. A mixed (QUAN-Qual) and quasi-experimental methodological approach was used for this study; two questionnaires were applied to 454 high school students and a focus group was performed with a group of seven professors. The quantitative analysis was processed with SPSS and consisted of ANOVAS and post hoc tests for more than two samples, while the focus group analysis was performed through inductive analysis. Results show benefits for professors and learners. Students improved their attitudes toward mathematics, reducing anxiety and improving willingness, while professors found a dynamic and optimal way to manage gamification on Gamit!

La gamificación es una técnica que permite utilizar en distintos contextos las que se presentan en los juegos. En la actualidad, existen varias iniciativas para aplicarla en contextos educativos, las cuales buscan impactar en la experiencia de los estudiantes mediante la mejora en la motivación (Surendeleg et al., 2014; Hamari et al., 2015; Rincón-Flores et al., 2018) y la atención de ellos (Hamari & Keronen, 2017). Para una correcta aplicación de la gamificación, es necesario basarse en alguna metodología que ordene y facilite su adopción, así como una herramienta que dinamice su utilización por parte de los docentes y los estudiantes. Gamit! Es una plataforma tecnológica de gamificación cuyo valor radica en facilitar la adopción de esta técnica mediante una metodología basada en narrativas.

The task of elaborating accurate test suites for program testing can be an extensive computational work. Mutation testing is not immune to the problem of being a computational and time-consuming task so that it has found relief in the use of heuristic techniques. The use of Genetic Algorithms in mutation testing has proved to be useful for probing test suites, but it has mainly been enclosed only in the field of imperative programming paradigms. Therefore, we decided to test the feasibility of using Genetic Algorithms for performing mutation testing in functional programming environments. We tested our proposal by making a graph representations of four different functional programs and applied a Genetic Algorithm to generate a population of mutant programs. We found that it is possible to obtain a set of mutants that could find flaws in test suites in functional programming languages. Additionally, we encountered that when a source code increases its number of instructions it was simpler for a genetic algorithm to find a mutant that can avoid all of the test cases.

Los videojuegos son productos digitales que se vienen aplicando en diversos contextos que no son necesariamente lúdicos dado que contienen características que permiten la mejora de diversas habilidades de parte de los videojugadores. En el presente artículo se realiza una revisión de las tendencias en la aplicación de videojuegos en la industria y en la educación, tomando como marco el modelo MDA (Mechanics, Dynamics y Aesthetics), así como se revisan algunas definiciones de conceptos necesarios para el entendimiento y análisis de estos productos digitales. Al final, se concluye en la impor­tancia de los videojuegos por su capacidad de generar motivación y enfoque, por lo que su aplicación en entornos distintos a los de entretenimiento generaría muchos beneficios.
