Teaching machine learning in robotics interactively: the case of reinforcement learning with Lego® Mindstorms

Preparing students for dealing with a world more and more densely populated with physical machines that possess learning capabilities, e.g. intelligent robots, is of the utmost importance in engineering. In this paper, we describe and analyse a design of interactive sessions devoted to the application of some machine learning (ML) methods within a master degree subject named “Cognitive Robotics”, in particular, reinforcement learning (RL), a technique that allows the machine to autonomously learn decision-making in a physical environment. The paper contains a complete depiction of the interactive teaching sessions, implemented with reasonable cost and resources thanks to a suitable mixture of the constructivist and instructivist paradigms. It also gathers the experiences of students and teachers through both qualitative and quantitatively indicators.     

Curriculum analysis and education for sustainable development in Iceland

The article explores how the Icelandic public school curriculum for early childhood, compulsory and upper secondary school deals with education for sustainable development. As the curriculum does not often mention the term sustainability, a key with which to investigate signs of education for sustainable development in the three curricula was created. The key encourages a holistic view of sustainable development, where economic, environmental and social factors are not treated as separate entities. It was designed to reflect the goals of the United Nations Decade of Education for Sustainable Development (2005–2014) with research on environmental education and education for sustainable development in mind. The key has seven characteristics: values, opinions and emotions about nature and environment; knowledge contributing to a sensible use of nature; welfare and public health; democracy, participation, and action competence; equality and multicultural issues; global awareness; and finally, economic development and future prospects. Using the key, a variety of signs and indicators that provide a space for teachers and schools to deal with issues of sustainable development were identified.

Can Interactive Web-based CAD Tools Improve the Learning of Engineering Drawing? A Case Study

Many current Web-based learning environments facilitate the theoretical teaching of a subject but this may not be sufficient for those disciplines that require a significant use of graphic mechanisms to resolve problems. This research study looks at the use of an environment that can help students learn engineering drawing with Web-based CAD tools, including a self-correction component. A comparative study of 121 students was carried out. The students were divided into two experimental groups using Web-based interactive CAD tools and into two control groups using traditional learning tools. A statistical analysis of all the samples was carried out in order to study student behavior during the research and the effectiveness of these self-study tools in the learning process. The results showed that a greater number of students in the experimental groups passed the test and improved their test scores. Therefore, the use Web-based graphic interactive tools to learn engineering drawing can be considered a significant improvement in the teaching of this kind of academic discipline.     

A systematic review on small-sided games in football players: Acute and chronic adaptations

Small-sided games (SSG) are played on a small pitch, often using modified rules and involving a smaller number of players. This article aimed to critically analyse the literature to determine how small-sided games affect the performance of football players in the short- and long term. Electronic databases were searched for literature dating from January 2000 to July 2018. The methodological quality of the studies was evaluated using the modified Downs and Black Quality Index (cross-sectional studies) and the Physiotherapy Evidence Database (PEDro) scale (intervention studies). Fifty-three studies, 44 cross-sectional and 9 intervention studies, met the inclusionary criteria for review. Most of the cross-sectional studies focused on describing the differences between SSG protocols, whereas 4 studies focused on making a comparison between “interval” and “continuous” SSG training regimes. On the other hand, intervention studies focused on making a comparison between SSG-based protocols and high-intensity intermittent training (HIIT)-based running protocols, in addition to determine the effect of a SSG-based training programme alone. SSG-based football plans (2 to 4 SSG sessions per week) show athletic performance improvements in football players by improving sprint, repeated sprint ability (RSA) and change of direction (COD) along with muscular and physiological adaptation.     

Comparing effects of a TPSR training program on prospective physical education teachers’ social goals,discipline and autonomy strategies in Spain,Chile and Costa Rica

Background: Conflict prevention, respect, tolerance and acceptance of others should be basic outcomes in any educational context. Physical Education (PE) has the potential to be one of the curricular subjects that could help students meet these goals. However, teachers need to use appropriate instructional approaches like Teaching for Personal and Social Responsibility (TPSR).

Purpose: The objectives of this study were two: (1) to compare the impact of TPSR training on social goals, discipline strategies and autonomy support of future PE teachers from Spain, Chile and Costa Rica; and (2) to assess participants’ perceptions of their country's social, cultural and curricular aspects that may influence TPSR implementation.

Participants and settings: 156 prospective PE teachers (48 from Spain, 54 from Chile and 54 from Costa Rica), with an average age of 21.41?±?2.57 years, agreed to participate. 88 (54%) were males, while 75 (46%) were female. They were enrolled in teacher training programs in three different universities located in three different countries: (i) Faculty of Education of the University of Burgos (Spain); (ii) Nursery School of the University of Valparaiso (Chile) and (iii) School of Physical Education and Sports of San José (Costa Rica). All students experienced the same TPSR intervention program, conducted by the same university teacher.

Research design: This study followed a quasi-experimental, pre-test/post-test non-equivalent research design with mixed methods.

Data collection: Three validated questionnaires were used to obtain quantitative information from the participants before and after the training program. Qualitative information was obtained from three discussion groups conducted with the participating students (one from each country).

Data analysis: Statistical analysis of quantitative data was conducted with the statistical package SPSS (version 22.0), while content analysis and constant comparison were used to assess qualitative data.

Findings: The prospective PE teachers from the three countries held different views of the effects of the TPSR program on social goals, discipline strategies and autonomy support, and they were based on socio-cultural considerations of the subject (PE), the teachers’ academic training and their professional identity as teachers on each country. Spanish and Costa Rican PE teachers demonstrated a significant positive change in their perspectives on discipline strategies, and Chilean PE teachers demonstrated a significant positive change in their perception of social goals after experiencing a TPSR intervention.

Conclusion: If cultural context is considered, TPSR can be an effective teacher training approach related to discipline strategies, social goals and autonomy support in PE.     

Effects of a nonlinear pedagogy intervention programme on the emergent tactical behaviours of youth footballers

Purpose: This study analysed the effects of a training intervention programme using principles of Non-Linear Pedagogy (NLP) on the decision making (DM) and performance behaviours (P) of youth footballers.

Method: 19 footballers (U12 yrs) participated in 14 training sessions, spread over three phases: Pre-intervention, Intervention, Retention. The intervention was based on Small-Sided and Conditioned Games. We assessed progress during the intervention phase at two different points: intermediate and final. The GPET instrument was used to analyse the DM and P during the completion of 3208 passes in the intervention.

Results: Results shown significant improvements in the DM and P after the intermediate and final points of the acquisition phase. Moreover, significantly higher values were also obtained in both variables in the retention, compared to the pre-intervention phase.

Conclusion: Results indicated that the NLP intervention programme was effective in improving both aspects of team games performance in youth players, with effects consolidated over time.     

The impact of EU-funded development interventions on teaching practices in Hungarian schools

This article analyses the impact of EU-funded curriculum development interventions implemented in Hungary between 2004 and 2012, focusing on contextual features influencing school- and teacher-level adoption processes. It is based on a four-year empirical study which aimed at better understanding the impact mechanisms of modernising interventions targeted at school and classroom level teaching practices. The results show that: (1) EU-funded curriculum development programmes have had a significant impact on a large number of Hungarian schools (ISCED 1, 2 and 3), (2) interventions were particularly effective in schools operating as knowledge-intensive organisations and (3) the impact of interventions was influenced by the specificities of both the programme and the local context of adoption. The first part of the article presents the theoretical framework of the research and the main characteristics of EU-funded curriculum-development programmes. The following section explores the key features of the research, including its purpose, design and survey instruments. The last part presents the main outcomes, showing the measured impact of interventions on everyday practices of both schools as organisations and individual teachers, as well as the possible links between organisational characteristics and the success of programme implementation.     

Applying the EFQM model to golf course management

The European Foundation for Quality Management (EFQM) Excellence Model provides guidance and support for business organisations to improve their quality management. This goal is attained by examining the relations among the several criteria that are defined and included in the model – the Enablers and the Results – albeit without going deeply into their empirical correlations. Our research focuses on the sport industry and, more particularly, on golf-related services and facilities. We analyse their management and performance. The goal is to conduct an empirical study of golf courses making up the supply in a Spanish inland region. On the basis of data and assessments contributed by the participating sample – and by resorting to multivariate statistical analysis – we pinpoint the influence of all Enablers identified by the EFQM Model, as well as their impact on the Results criteria. Correlations designed and empirically quantified make it possible for us to confirm the theoretical interrelations that the EFQM Model proposes between the defined criteria. The structural model thus obtained allows us to design a map that plots the relationships across the several criteria defined by the EFQM Model, one which portrays present-day approaches to management put into practice by the golf courses under scrutiny.
