The aim of this study was to identify the dynamics of tactical behaviour emerging on different timescales in football small-sided games and to quantify short- and long-term exploratory behaviour according to the number of opponents. Two teams of four professional male footballers played small-sided games against two different teams with a variable number of opponents (3, 5 and 7). Data were collected using a combination of systematic observation and a non-differential global positioning system (15 Hz). The temporal diversity and structural flexibility of the players were determined by calculating the dynamic overlap order parameter q, entropy and trapping strength. Analysis of the exploratory dynamics revealed two different timescales, forming a different metastable landscape of action for each constraint. Fast dynamics lasted on average a few seconds and consisted of changes in tactical patterns. The long timescale corresponded to the shared tasks of offence and defence lasting tens of seconds. The players’ tactical diversity decreased with an increasing number of opponents, especially in defence. Manipulating numerical imbalance is likely to promote changes in the diversity, unpredictability and flexibility of tactical solutions. The fact that the temporally nested structure of constraints shaped the emergence of tactical behaviour provides a new rationale for practice task design. The manipulation of numerical imbalance on the timescale of a few tens of seconds, on which the exploratory behaviour of players saturates, may help coaches to optimise the exploratory efficiency of the small-sided games. 相似文献

Results are reported in this paper from a study aimed at evaluating significant competencies in final-year students of some engineering programmes in Chile. The study was carried out by a group of eight universities that were interested in exploring ways to assess learning outcomes such as those demanded by the recent Chilean accreditation system. The authors actively participated in all stages of the study, contributing directly to the design, application and results evaluation of some tests. A sample of 150 students was tested, under conditions that guaranteed the comparability of results. In this paper the authors present results relating to the evaluation of effective communication. The study was backed up by a conceptual model and some hypotheses that are explained and discussed in this work. 相似文献

In recent years, an increasing number of students with specific learning disabilities (SLDs) have enrolled in universities. The present exploratory study examined the frequency of use and appreciation of universal (open to every student) and specific services (offered to students with SLDs) and their relation to age, academic achievement, satisfaction, self-efficacy, and use of self-regulated learning (SRL) strategies. Participants were 147 Italian university students with SLD diagnoses (42 males; mean age: 22.49, SD = 3.29). Results showed that, overall, the frequency of use and appreciation of specific services were positively related to academic satisfaction, self-efficacy, and SRL strategies. Furthermore, frequency of use of compensatory tools and dispensatory measures was positively associated with academic achievement. These findings suggest that universities play an important role in supporting students with SLDs during their academic years by providing them with useful services and accommodations. 相似文献

Over the past 20 years, the USA has seen more than its fair share of controversy with respect to education about sexuality, sex and intimate relationships. Attention has focused on content (abstinence-only vs. comprehensive instruction), delivery (by teachers, parents, health professionals or community educators) and context (within school and beyond). In recognition of this fact, Sex Education invited the development of a virtual special issue comprising a sample of its most impactful papers on these and related topics. The 2016 Presidential election results and recent legislative action in the USA point to the importance of thinking broadly about teaching and learning about sexuality inside and outside of schools and of considering sexuality as it intersects with categories of difference, privilege and penalty, including ability, age, immigration, race, gender and class. This paper, developed as an introduction to the virtual special issue, opens with a discussion of the journal’s contributions to the ongoing discussion of pleasure and desire in sexuality education. From there, we turn to the question of what is possible given the material and ideological conditions of schooling and then to opportunities for teachers and learners outside the conventional classroom. We follow with a discussion of the place of intersectional analyses in sexuality education research, and conclude with some thoughts on sexuality education research at this political moment. 相似文献

The Atlas of Erotic Anatomy and Arousal is online video education that explores sexual pleasure and sexual anatomy from a sex positive perspective. Written and presented by a sex educator and therapist, Cyndi Darnell, this video is an excellent resource for adult individuals interested in learning about their bodies and having fulfilling sexual experiences with their partners. The video series provides scientifically accurate and pleasure-based information about the anatomy of the vulva, the penis, and the anus, and the physiology of orgasm and ejaculation, in an entertaining manner. 相似文献

This study approaches teacher learning from a dialogical viewpoint where lecturers’ voices used in a training course context reflect how lecturers generated new professional discourse. The design of the training course considered the analysis of several critical incidents (CIs) in online teaching. An analytical framework based on lecturers’ discourse and ways of thinking about teaching was used to identify types of renaming teaching practice. The empirical element of the study analysed the written utterances about teaching provided by 12 online instructors in order to determine what kinds of new discourse emerged during the analysis of 15 CIs in online teaching. Results showed that local discourse is the lecturers’ most commonly used discourse, prototypical incidents generated more professional discourse than personal and real CIs, and professional discourse can be created by means of at least nine different ways of articulating discourse. On the basis of these results, some pedagogical implications for lecturer learning are discussed. 相似文献
