Quantification of the physiological loading of one week of "pre-season" and one week of "in-season" training in professional soccer players

The aim of this study was to quantify the physiological loads of programmed "pre-season" and "in-season" training in professional soccer players. Data for players during each period were included for analysis (pre-season, n = 12; in-season, n = 10). We monitored physiological loading of training by measuring heart rate and rating of perceived exertion (RPE). Training loads were calculated by multiplying RPE score by the duration of training sessions. Each session was sub-categorized as physical, technical/tactical, physical and technical/tactical training. Average physiological loads in pre-season (heart rate 124 ± 7 beats · min(-1); training load 4343 ± 329 Borg scale · min) were higher compared with in-season (heart rate 112 ± 7 beats · min(-1); training load 1703 ± 173 Borg scale · min) (P < 0.05) and there was a greater proportion of time spent in 80-100% maximum heart rate zones (18 ± 2 vs. 5 ± 2%; P < 0.05). Such differences appear attributable to the higher intensities in technical/tactical sessions during pre-season (pre-season: heart rate 137 ± 8 beats · min(-1); training load 321 ± 23 Borg scale · min; in-season: heart rate 114 ± 9 beats · min(-1); training load 174 ± 27 Borg scale · min; P < 0.05). These findings demonstrate that pre-season training is more intense than in-season training. Such data indicate that these adjustments in load are a direct attempt to deliver training to promote specific training adaptations.     

‘I do not think I actually do it well’: a discourse analysis of Australian senior secondary teachers’ self-efficacy and attitudes towards implementation of differentiated instruction

Differentiated instruction is a proactive teaching model and philosophy with demonstrated potential to cater for diverse learners and create inclusive classrooms. There is little research, however, into the implementation of this approach in the senior secondary classroom. Teachers’ implementation of differentiated instruction has been shown to be linked to teacher attitudes and self-efficacy in other settings. This study investigated the impact of teachers’ self-efficacy and attitudes towards the implementation of differentiated instruction in the senior secondary context across two Australian states with a total of five participating teachers. The A (Affective) B (Behaviour) C (Cognitive) model was employed to define teacher attitudes from interviews concerning differentiated instruction. Findings indicated that teacher knowledge was a major factor influencing differentiation, in addition to attitude and self-efficacy. The discourse analysis demonstrated that teachers held a greater knowledge of differentiation strategies than the concepts that underpin the differentiated instruction framework. Additionally, time constraints and feelings of failure in implementing differentiation strategies impacted teacher attitudes. Teacher knowledge, attitude and self-efficacy were interrelated and impacted on teachers’ implementation of differentiated instruction in the senior secondary classroom. Implications for professional development to address student needs through differentiated instruction in the inclusive senior secondary classroom teacher are discussed.     

English in action: school based teacher development in Bangladesh

In the Least Economically Developed Countries (LEDCs), School Based Teacher Development (SBTD) is sometimes advocated as a potential mechanism for improving the classroom practices experienced by millions of children in a complete school system, as quickly as possible. Robust evidence is required for approaches to be implemented with some confidence by Government development agencies, such as the UK Department for International Development (DFID). SBTD has a long history stemming from ideas of school-based curriculum development, which underlay the ideas on teacher-as-researcher, and is typically advocated in the developed world based on a view of the teacher as a professional. How might such notions play out, and to what effect, in LEDC contexts? This article examines the issues at stake in introducing SBTD in LEDCs, by examining: the nature of the evidence for various forms of teacher development, the nature of SBTD in particular and the evidence for its effectiveness. The latter issues will be illustrated through examination of English in Action (EIA, www.eiabd.com), a large-scale SBTD programme for primary and secondary English language (EL) teachers serving government schools across Bangladesh.     

Short reports

While Western educators caution against contrived collegiality in the midst of enthusiasm for peer coaching as a form of teacher development, Hong Kong educators are struggling to detach discussion and observation of classroom teaching from staff appraisal. The challenges for this task are twofold: to secure a niche for peer coaching in the practice of staff development, and to ward off contrived collegiality in the course. Using an action research paradigm, the present project attempted to meet these challenges in two schools. As a joint work between various parties, the present project had to negotiate its way cautiously to achieve genuine collaboration and avoid imposition from the administrators and outsiders to the front-line teachers. During the course, innovative strategies were taken to cope with various difficulties, including time constraints, teachers' psychological pressure, and the possibility of contrived collegiality and implementation partnership. The evaluation of the project showed that the teachers generally accepted peer coaching and found it helpful to their professional development. The experience in the two schools indicated that true collaboration might emerge from organizationally induced collegiality under certain conditions.     

Metaphors and client change in counselling

Counseling is a primarily verbal activity where it can often be difficult to differentiate the literal from the metaphorical in clients' communications. Acceptance of metaphor as a genuine form of clients' experience and communication could provide counselors with viable medium for effecting change. Understanding our clients' metaphors, utilizing their metaphors for change, or constructing and presenting our own therapeutic metaphors requires learning certain skills and awarenesses. After a brief theoretical examination of metaphors and metaphoric processing, this article outlines skills and considerations for recognizing, using, creating, and delivering effective metaphors in counseling.     

Solving graphics tasks: Gender differences in middle-school students

The capacity to solve tasks that contain high concentrations of visual-spatial information, including graphs, maps and diagrams, is becoming increasingly important in educational contexts as well as everyday life. This research examined gender differences in the performance of students solving graphics tasks from the Graphical Languages in Mathematics (GLIM) instrument that included number lines, graphs, maps and diagrams. The participants were 317 Australian students (169 males and 148 females) aged 9-12 years. Boys outperformed girls on graphical languages that required the interpretation of information represented on an axis and graphical languages that required movement between two- and three-dimensional representations (generally Map language).     

Continuing Education and the Redrawing of Boundaries

Continuing education, broadly defined to include both vocational and non-vocational kinds of provision, is having an increasing impact within higher education. Its further expansion is now part of government strategy. This expansion will not be achieved without difficulties, and it poses considerable and varied challenges to those who work in higher education. In this paper, we focus on the effects that continuing education is having on established boundaries within higher education — boundaries between different sectors and types of provision, between different subjects and ways of teaching, and between higher education staff and their different skills. As the provision of continuing education increases, existing boundaries will change, become more permeable or be broken down altogether while new divisions and distinctions are created and built up.     

IS THERE REAL OPINION CHANGE?

Public opinion research in general and the study of opinionchange in particular have frequently been challenged as unreliable.Attitudinal measurements are characterized as merely reflectingnon-attitudes, labile moods, and/or methodological artefacts.Given this basis, the measurement of opinion change is seenas a product of random variations and systematic biases ratherthan as reliably measuring true change. However, most opinionchange is (1) not chaotic, but slow and steady and (2) largelyexplicable. Even opinion change that is rapid and/or multi-directionalcan be plausibly explained. Measurement variation does howeveroften distort time series and greatly complicates the reliableassessment of true change.
