Differences in maturity,morphological and physical attributes between players selected to the primary and secondary teams of a Portuguese Basketball elite academy

The present study aims (i) to compare the maturational, morphological and fitness attributes of young basketball players of primary and secondary teams of an elite basketball academy, and (ii) to identify the set of morphological and fitness attributes which better discriminate the players from the two teams. A total of 116 male basketball players of an elite basketball academy were divided into primary (team A) and secondary (team B) teams in two age groups (U-14 and U-16). All the players were evaluated during two consecutive seasons and data related to players’ practice experience, maturational, morphological and fitness attributes were collected at the beginning of the competition period. The results of the study suggest that: (i) in both age categories, team A players were older, more mature, bigger in size and had greater fitness profiles than team B players; (ii) stature and abdominal resistance were identified as discriminant attributes for youth basketball player performance; (iii) aerobic capacity for U-14 and agility for U-16 were identified as specific discriminant attributes for performance in youth basketball. Coaches are recommended to avoid premature talent identification and provide players with opportunities to progress through the talent pathway, at least until U-16 age category.     

The evolution of student-coach’s pedagogical content knowledge in a combined use of sport education and the step-game-approach model*

Background: One of the essential elements within Sport Education is the inclusion of student roles and responsibilities. While previous research has examined students’ performance in officiating tasks, the examination of student-coaches’ pedagogical content knowledge (PCK) within peer-assisted tasks of Sport Education has been scarce. Indeed, the only study to date which has examined student-coach effectiveness was conducted by Wallhead and O’Sullivan [2007. “A Didactic Analysis of Content Development During the Peer Teaching Tasks of a Sport Education Season.”Physical Education and Sport Pedagogy 12 (3): 225–243]. In that study, student-coaches struggled to manifest PCK by providing appropriate demonstrations, to diagnose errors, or to modify tasks for higher order content development. The study of PCK may be a useful heuristic to examine instructional effectiveness in physical education.

Purpose: The purpose of this study was to examine the evolution of the PCK of a cohort of student-coaches across three hybrid Sport Education-Step Game Approach seasons, and to examine the impact of protocols put in place to specifically enhance coaches’ PCK.

Participants and setting: Twenty-one students and one teacher from a school class in the north of Portugal participated in the present study.

Method: Data from multiple sources were collected: (a) videotape observations of all lessons, (b) field notes, and (c) pre-lesson interviews with the student-coaches. These were then subjected to deductive examination through a process of thematic analysis.

Findings and conclusions: Following a baseline season that identified four key limitations within the student-coaches’ instruction (task presentation, error diagnosis, feedback, and task modification), these students participated in specific coach preparation that involved modelling teacher’s instruction, pre-lesson meetings, and coaches’ corners. While showing marked improvement in their content knowledge across the second season, a second protocol was instigated during the third that involved the student-coaches to participate in stimulated reflections of their instruction and the incorporation of planning sheets to enhance their instruction. It was found that both interventions were efficacious in developing student-coaches’ PCK, which allowed a more complete transfer of the instructional responsibility from the teacher to the students. These results give insight into the importance of including coach education protocols within the design of seasons of Sport Education with respect to student-coaches’ instructional preparation.

The construction of a transnational Lusophone media space: A historiographic analysis

This piece examines the historical construction of a Lusophone cultural-linguistic media space and market that spans portions of Europe, Africa, and South America. Beginning with the Portuguese colonization of Brazil and Lusophone Africa in the 17th century and continuing to the contemporary moment, our discussion examines how a combination of political, ideological, and economic patterns created linkages between Portugal, Brazil, and Portuguese-speaking colonies in Africa (namely Angola, Cape Verde, and Mozambique). After examining how Brazil grew to become the dominant cultural producer in this transnational matrix (most explicitly expressed through the massive exports of telenovelas and music since the late 1970s), we examine how other countries are beginning to carve out distinctive national niches, including the contemporary music scene in Cape Verde and the rise of domestically produced telenovelas in Portugal and Angola that are increasing in circulation in the contemporary transnational Lusophone media space.     

A Multi Proxy Investigation of Moisture,Salt, and Weathering Dynamics on a Historic Urban Boundary Wall in Oxford,UK

ABSTRACT

Boundary walls are neglected but important parts of historic urban environments, and they are often prone to serious deterioration. Understanding moisture and salt dynamics within boundary walls can help infer the causes and dynamics of deterioration. This investigation investigates the patterns of moisture, salt, and deterioration on a 300 year old limestone boundary wall in Worcester College, Oxford. Multiple methods to assess moisture and salts within and across the wall (electrical resistivity tomography, handheld resistivity-based moisture meter, paper pulp poultices, scanning electron microscopy, inductively coupled plasma optical emission spectrometry, and ion chromatography of small scale sampling of deteriorated limestone) were used in conjunction with decay mapping of both sides of the wall. The salt weathering strongly correlates with severely weathered zones at the wall and salts, mainly sulfates, seem to be the main agent of decay processes. The combined results demonstrate that the environmental influences driving stone decay can differ on a very small scale even at a comparatively simple structure like a boundary wall, and that repairs can have adverse effects if the patterns of salt and moisture dynamics are not sufficiently known.     

Design and evaluation of a computer game for the learning of Information and Communication Technologies (ICT) concepts by physical education and sport science students

This study addresses the learning of Information and Communication Technologies (ICT) concepts by physical education and sport science students through a computer game. Its aims are: (a) the design of the prototype of a computer game aimed at supporting the development of an appropriate mental model about how a computer works by the students, and (b) the evaluation of the impact of the use of this prototype on students as to appeal, basic usability issues and learning outcomes. The most significant elements of the game prototype (narrative, characters, interface, scenarios, puzzles, gameplay) are presented in connection with the constructivist learning principles that guided the game design. A hundred and three (103) physical education and sport science students participated in the evaluation of the game prototype, which was conducted through pretest and posttest written questionnaires that elicited both quantitative and qualitative data. The data analysis showed that the game prototype was well-accepted as an alternative learning tool for ICT, compared to traditional learning tools, and that most game elements elicited average to positive responses from the students. It was also found that the game prototype had a significant positive effect on students’ knowledge regarding the concepts of input, program, output and their interplay, and that it helped certain students overcome their misconceptions and form more scientifically acceptable and elaborate mental conceptions about basic functions of a computer. Future improvements and extensions to the game as well as future research perspectives are discussed on the basis of the findings.     

Exploring preservice teachers' attitudes towards inclusion

This study responds to a call for research into existing teacher-education programmes and their impact on teacher candidates' attitudes. An inclusive education course that examined the difference between ‘soft inclusion’ (inclusion which addresses the issue of place rather than substance of learning) and genuine inclusion was used to explore pre-existing teacher candidate beliefs and assumptions. Using the Opinions Relative to Mainstreaming-Adapted, four classes of students from two different teacher-preparation programmes within the Faculty of Education at York University in Toronto, Canada, were surveyed pre- and post-course. A statistically significant change in the scores was found for all of the classes. A significant difference was also found between the changes in scores of the two programme groups. Results indicate that the course was successful at shifting preservice students towards inclusion and gave the students a foundation that will hopefully translate into practice.     

Changing the teaching/learning procedures in physics for agricultural engineering. A case study

The subject ‘Physical Fundamentals of Engineering’ for agricultural engineers in the University of Extremadura has long had high rates of students not attending classes, not presenting for examinations and, finally, failing the subject. During the 2007 and 2008 courses, the teaching/learning procedures were strongly modified. Analysis of the proportion of students taking final examinations and of the final marks shows that the new procedure leads to a satisfactory progress in most of the objectives, including a general improvement in their marks and pass rates. In particular, it was found that the new procedure needs to be maintained by the teachers for at least two courses for the greatest success.     

The Effects of Special Curricular Study of Mexican Culture on Anglo and Mexican-American Students’ Perceptions of Mexican-Americans

Anglo and Mexican-American students in six sixth-grade classrooms were randomly assigned to control or experimental conditions (four weeks of special curricular study of Mexican culture). The effect of the treatment on perceptions of MexicanAmericans was studied by having students respond anonymously to an attitude inventory. The posttest means were significantly lower than the pretest means for all groups, apparently as a consequence of greater honesty in responding. There were significant differences in the ethnic group means, but no sex difference. The length and intensity of the treatment were not sufficient to cause changes in the ethnic attitudes and stereotypes.
