Title- Experiences Using QR Codes for Improving the Teaching-Learning Process in Industrial Engineering subjects

Abstract- The number of mobile phones and tablets has notably been raising in last few years, which allows to extend its potential applications. In the field of education, the possibilities offered by augmented reality are yet to be explored. The experience which is proposed in this paper pretends to implement QR codes in subject teaching belonging to an industrial engineering degree. In particular, changes are shown in two subjects (electronic instrumentation and thermal engineering), with the aim to improve the learning process with the use of QR codes in the practices of both subjects. An opinion test was used to evaluate the undergraduate’s acceptance rate and satisfaction with this new technology proposed. The results of this survey were satisfactory and support the proposal to use mobile technology as part of the learning process.

Title- On incorporating affective support to Intelligent Tutoring Systems: an empirical study.

Abstract- Previous research studies have reported strong evidence that the emotional state of the student may have a considerable impact on their learning. In this paper, we present an empirical study that evidences that it is possible to influence the user’s affective state in a controlled way, by adapting the system’s response. As part of this study, we have analyzed the affective impact of varying the level of help provided in an existing Intelligent Tutoring System. Results show that it is possible to use classification approaches to predict positive and negative variations in dominance, valence, arousal and performance to a reasonable level of accuracy.

Title- Personalized tests for formative self-evaluation

Abstract- This article presents the design and application of personalized formative self-assessment tests, in the framework of adaptive learning in Virtual Learning Environments (VLE). The tests were customized taking into account the predominant learning styles in the groups and the knowledge level of the domain item. The experience compares two groups of university students, belonging to different semesters of the same course, following the approach of continuous improvement. The results show significant improvement in the learning process in the second group, which is shown in the results of midterm exams.

Title- Self-regulated learning in a computer programming course

Abstract- This article contains an exploratory study on self-regulation by a group of students during a second year computer programming course (data structures). Self-regulation was measured through the implementation of an instrument that evaluates motivation and learning strategies. From the results of the implementation, the relation between self-regulation and academic performance among the students was studied through a correlation analysis and other multivariate analyses. The results show new empirical pieces of evidence on the role played by self-regulation within the educational context of computer programming, and suggest which combination of factors allows to discriminate the population subgroups between high and low academic performances, according to self-regulated learning variables.
