A Case Study on Learning visual programing with TutoApp for Composition of Tutorials: An approach for Learning by Teaching
(IEEE, 2022) Paredes-Velasco, Maximiliano; Lozano-Osorio, Isaac; Pérez-Marín, Diana; Santacruz-Valencia, Liliana Patricia
Teaching programming is a topic that has generated a high level of interest among researchers in recent decades. In particular, multiple approaches to teaching visual programming have been explored, from the use of tools such as Scratch, robots, unplugged programming or activities for the development of computational thinking. Despite the wide range of resources used, students generally tend to perform poorly academically and perceive learning visual programming as a complex and demotivating task. In this article, the TutoApp system is proposed together with a new methodology based on "Learning by Teaching”, where students create tutorials in their mobile devices to explain programming concepts to their peers. The hypothesis of this paper is that the use of this tool improves learning outcomes and the level of student satisfaction. An experiment with a pre-post- test design has been carried out with 57 university students in an introductory programming course, 30 belonging to a control group (did not use TutoApp) and 27 belonging to the experimental group (used TutoApp). The findings indicate that the creation of tutorials with TutoApp significantly improved students' academic performance over those who did not use it, specifically in learning the loops and conditional control structures. However, it was observed that anxiety increased in all students while learning visual programming. The results of this study open the door to the validation of the use of systems and methodologies for creating tutorials for teaching visual programming to university students.
APRENDER ENSEÑANDO: CREACIÓN DE TUTORIALES CON TUTOAPP EN EL ÁMBITO DE FORMACIÓN PROFESIONAL
(2023-11) Ruiz-Omedilla, Sonia; Lozano-Osorio, Isaac; Paredes-Velasco, Maximiliano
El auge de las metodologías activas en educación y su importancia para atender a la diversidad presente en las aulas, se plantea como una oportunidad para realizar una intervención en la etapa de Formación Profesional introduciendo la metodología activa aprender enseñando, utilizando tecnología móvil a través de una aplicación Android, llamada TutoApp. Con esta aplicación los estudiantes crean tutoriales y breves cuestionarios relacionados con los contenidos a trabajar, de manera que este material facilite el aprendizaje tanto a sus creadores como al resto de compañeros. En la intervención descrita se valoran las emociones experimentadas por los estudiantes antes y después de la experiencia junto al rendimiento académico. La experiencia apunta a un mayor rendimiento en el aprendizaje y el dominio de los contenidos trabajados de los alumnos que usaron la herramienta de TutoApp respecto a los que no lo usaron. Sin embargo, no se encontró que el uso de la herramienta mejorase significativamente el estado emocional de los estudiantes.
Dynamic Path Relinking for the Target Set Selection problem
(Elsevier, 2023) Lozano-Osorio, Isaac; Oliva-García, Andrea; Sánchez-Oro, Jesús
This research proposes the use of metaheuristics for solving the Target Set Selection (TSS) problem. This problem emerges in the context of influence maximization problems, in which the objective is to maximize the number of active users when spreading information throughout a social network. Among all the influence maximization variants, TSS introduces the concept of reward of each user, which is the benefit associated to its activation. Therefore, the problem tries to maximize the reward obtained among all active users by selecting an initial set of users. Each user has also associated an activation cost, and the total sum of activation costs of the initial set of selected users cannot exceed a certain budget. In particular, two Path Relinking approaches are proposed, comparing them with the best method found in the state of the art. Additionally, a more challenging set of instances are derived from real-life social networks, where the best previous method is not able to find a feasible solution. The experimental results show the efficiency and efficacy of the proposal, supported by non-parametric statistical tests.
Questionnaires to measure emotions and learning outcomes in a vocational training experience with Learning by Teaching
(Serie de Informes Técnicos DLSI1-URJC, 2024-04) Lozano-Osorio, Isaac; Ruiz-Olmedilla, Sonia; Perez-Marin, Diana; Paredes-Velasco, Maximiliano
The present work presents the questionnaires used in an experiment conducted with vocational training students, which measured the impact of the Learning by Teaching methodology on students' emotions and academic outcomes. First, the context in which the experiment was conducted is briefly described, followed by the display of the questionnaires used, in both English and Spanish versions.
