Increasing students’ responsibility and learning outcomes using partial Flipped Classroom in a Language Processors course


Jaime Urquiza-Fuentes. 2020. IEEE Access, 8, 211211-211223

Abstract: More than twenty years have passed since the term Flipped Classroom was coined. Despite of the increasing interest in this teaching methodology, fields like Computer Science still need more research in order to judge the impact of this methodology in the learning process. This work presents a comparative study between traditional lectures and a partial application of the Flipped Classroom methodology in the subject Language Processors of a Computer Science degree. The study involved 158 students during two weeks and focused on practical contents of the subject. The results show that students in the Flipped Classroom group were more responsible of their learning process, consequently they got significant better learning outcomes either during or at the end of the learning process. Students’ satisfaction was highly positive as well. This work increases the amount of experiments about Flipped Classroom within the field of Computer Science. In addition, this work serves as an example of how to begin the transition from traditional lectures to the Flipped Classroom methodology.

Educational Impact of Syntax Directed Translation Visualization, a Preliminary Study


Damián Nicolalde-Rodríguez & Jaime Urquiza-Fuentes. 2018. 2018 IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC), Lisbon, Portugal, 1 - 4 October 2018.

Abstract: This work studies the effect of using software visualization to teach syntax directed translation, a complex topic within compiler subjects. A trial was conducted with 34 students using LISA as the visualization tool. It was divided in two phases. Firstly, student’s experience during compilers construction labs was studied, comparing LISA versus CUP. All participants used both tools and answered a questionnaire. LISA was scored as more motivational and easier to use. Moreover, key theoretical concepts were better identified with LISA. Secondly, a typical lecture (control group) was compared against a lecture using LISA (treatment group). Students were randomly distributed between both groups and answered a knowledge test following the lectures. Results showed that the treatment group significantly outperformed the control group. However, areas for improvement have been detected even in the treatment group. These improvements could be addressed by enhancing the visualization tool with features to increase student engagement..

A Novel Group Engagement Score for Virtual Learning Environments


Jorge Castellanos, Pablo A. Haya , Jaime Urquiza-Fuentes. 2017. IEEE Transactions on Learning Technologies ( Volume: 10, Issue: 3, July-Sept. 1 2017 ), pp 306-317

Abstract: STEM (Science, Technology, Engineering, and Math) education is currently receiving much attention from governments and educational institutions. Our work is based on active learning and video-based learning approaches to support STEM education. Here, we aimed to increase student's engagement through reflective processes that embrace video film-making, and subsequent on-line discussion and evaluation of those videos. We propose a group engagement score that takes into account both individual activity and similarity of participation, thus allowing corrective actions to be taken when unengaged students or groups are identified. We tested these ideas using our own social learning platform that combines the principal features of Social Networks with tools that facilitate collaborative learning design. This platform stimulates students' learning by means of two main reflective processes: participatory production and peer-review. We evaluated this platform and the learning approach it supports in an Object Oriented Programming course and identified interesting differences between group engagement and video ratings. Our principal conclusion is that greater teacher and student awareness of the ongoing activities and group engagement are needed.

Investigating the effect of realistic projects on students' motivation, the case of Human-Computer interaction course

Jaime Urquiza-Fuentes, Maximiliano Paredes-Velasco. Computers in Human Behavior 72 (2017) 692-700. doi: 10.1016/j.chb.2016.07.020

Abstract: The aim of this study is to test the effect of a concrete way to use practical exercises in a human-computer interaction course. Our approach is focused on lab sessions, replacing typical concrete exercises with realistic projects based on collaborative work, long term duration (the whole course instead of concrete labs) and multidisciplinary design interacting with real end-users. The realistic projects approach supports the practice of theoretical concepts together with professional skills development, e.g. social skills needed to interact with end-user without technical background. In order to assess this approach we have conducted a comparative study with three different groups involving 133 students. Two groups followed the realistic projects approach, the difference between them was end-users recruitment. End-users were recruited by teachers in one group and by the students in the other. The third group followed the typical approach. Our comparative study is based on students' motivation. We have chosen the Situational Motivation Scale as the measurement instrument. Results show that, independently from the end-user recruitment, students involved in realistic projects are significantly more motivated than students involved in the general approach. Thus, students involved in realistic projects perceive that these activities are useful or important for them.

Motivación de Estudiantes en la Asignatura de Interacción Persona-Ordenador con Prácticas Realistas

Jaime Urquiza-Fuentes y Maximiliano Paredes Velasco. 2015. Actas del III CONGRESO INTERNACIONAL SOBRE APRENDIZAJE, INNOVACIÓN Y COMPETITIVIDAD. CINAIC 2015. Ángel Fidalgo Blanco y Marisa Sein-Echaluce Lacleta (eds.) pp 726-731 Ed. Fundación Universidad Politécnica de Madrid, Madrid, España, 14 - 16 Octubre 2015.

Resumen: Esta contribución describe la implementación de prácticas basadas en la resolución de casos reales en la asignatura de Interacción Persona-Ordenador. La experiencia es multidisciplinar, donde estudiantes de Grados de Educación Infantil y Primaria han asumido el papel de usuarios finales (usuarios, de ahora en adelante), mientras que los estudiantes de Interacción Persona-Ordenador (diseñadores, de ahora en adelante) han trabajado en el diseño de una interfaz con fines educativos. La experiencia de los alumnos se realiza bajo un enfoque pedagógico colaborativo. En este escenario de aprendizaje activo es muy importante la motivación que presenta el alumno para su implicación y participación en la actividad. El objetivo de esta experiencia es doble. Por un lado evaluar mediante instrumentos validados el grado de motivación que genera en los alumnos la realización de la actividad práctica con esta pedagogía colaborativa multidisciplinar. Por otro lado se quiere comparar el grado de motivación en los alumnos que tiene esta metodología colaborativa multidisciplinar respecto a otras dos metodologías: una variante de la anterior y otra más clásica. Los resultados indican una mejora significativa en la motivación de los grupos de la metodología presentada con respecto a la clásica.

Students’ Motivation in the Subject of Human Computer Interaction with Realistic Projects

Abstract: This contribution describes the use of a project based learning methodology within the subject Human-Computer Interaction. The experience is multidisciplinary because two types of students are involved. Students enrolled in Kindergarten and Elementary Education degrees, which have assumed the role of end users, and students enrolled in Human-Computer Interaction, which have produced the design of an interface for educational purposes, assuming the role of designers. This experience follows a collaborative teaching approach. In this active learning scenario, the students’ motivation has an important effect on their involvement and participation in the activity. The objective of this experience is twofold. On the one hand, we wanted to assess, using validated instruments, the degree of motivation generated in students while working on the project activity with this multidisciplinary collaborative pedagogy. On the other hand, we wanted to compare the degree of motivation produced by this methodology with two other approaches: a variant of the above and other more classical. The results show a significant improvement in the motivation of the groups of the methodology presented in relation to classical one.
