This study estimated the expected point value for starting possessions in different field locations during rugby league match-play and calculated the mean expected points for each subsequent play during the possession. It also examined the origin of tries scored according to the method of gaining possession. Play-by-play data were taken from all 768 regular-season National Rugby League (NRL) matches during 2010–2013. A probabilistic model estimated the expected point outcome based on the net difference in points scored by a team in possession in a given situation. An iterative method was used to approximate the value of each situation based on actual scoring outcomes. Possessions commencing close to the opposition’s goal-line had the highest expected point equity, which decreased as the location of the possession moved towards the team’s own goal-line. Possessions following an opposition error, penalty or goal-line dropout had the highest likelihood of a try being scored on the set subsequent to their occurrence. In contrast, possessions that follow an opposition completed set or a restart were least likely to result in a try. The expected point values framework from our model has applications for informing playing strategy and assessing individual and team performance in professional rugby league. 相似文献

Significant claims about science education form an integral part of Thomas Kuhn's philosophy. Since the late 1950s, when Kuhn started wrestling with the ideas of normal research and convergent thought, the nature of science education has played an important role in his argument. Hence, the nature of science education is an essential aspect of the phase-model of scientific development developed in his famous The Structure of Scientific Revolutions, just as his later work on categories and conceptual structures takes its starting point in the transmission rather than the creation of concepts and categories. 相似文献

Taking into account the pressing need to understand more about what teacher educators’ professional development characterises, this article adopts a mixed method approach to explore Flemish (Dutch-speaking part of Belgium) teacher educators’ professional development needs and opportunities. Analysis results of a large-scale survey study with 611 teacher educators and analysis of five qualitative focus groups (with 24 teacher educators) are presented. The results confirm the lack of attention for teacher educators’ professional development in the Flemish teacher education system. Moreover, the findings indicate a structural need for participation in professional development activities that are linked to teacher educators’ own practices, organised as long-term sustainable professional development trajectories, and formally recognised. To conclude, a professional development agenda for research, policy and practices related to teacher educators’ professional development is discussed. 相似文献

Dyslexia is hard to diagnose in a second language. Poor performance on a test of reading may be caused by poor language proficiency in the second language or by limited schooling rather than by poor reading ability per se. This confound was supported in a study of 88 adult second language learners and 65 native language speakers. The incidence of dyslexia in the second language learners varied widely depending on the measure of reading. In order to reduce language and schooling confounds, a dynamic test of acquisition of basic decoding ability was developed. In the dynamic test, participants are taught three novel letters and to synthesise the letter sounds into new words. Results from the study indicated that the dynamic test provided results in accordance with the current IDA definition of dyslexia, while significantly reducing the influence second language vocabulary and amount of schooling. With the dynamic measure, the same cut-off point between dyslexic and non-dyslexic performance appeared valid in both native language speakers and second language learners. 相似文献

Over the last decades, much research on peer learning practices has been conducted. Quantitative, experimental designs focusing on problems of cause and effect dominate. Consequently, effects on achievement are well documented, as is the influence of different conditions on the effect rate. In spite of the general acknowledgment of the importance of peer learning and a large amount of research on collective learning practices, questions regarding the quality of peer interaction, and how peer relations influence learning, are not well elaborated. This paper complements the discussion on effect focusing on the processes of interaction between peers, and relates these to theoretical perspectives on learning as fundamentally social. Inspired by meta-ethnography an integrative analysis across seven qualitative studies was accomplished. The approach enabled an investigation of peer interactions in different educational settings. The analysis elaborates on how instructional designs and students’ relational knowledge mediate interaction in peer learning. The paper further discusses the potential of approaches synthesising qualitative studies as a tool in qualitative research. 相似文献

A survey covering the scientific and social aspects of climate change was administered to examine U.S. undergraduate student mental models, and compare knowledge between groups based on major and environmental group membership. A Knowledge Score (scale 0–35, mean score = 17.84) was generated for respondents at two, central East Coast, U.S. universities (n = 465). Elements of student mental models examined include environmental issue confusion, skepticism, and self-reported understanding. This study finds that students frequently confuse climate change with other environmental issues, and that a substantial majority of students do not have an understanding of climate change that closely matches the scientific model. These misconceptions extend to their understanding of mitigation actions. Environmental group membership is shown to be a greater determinant of climate change knowledge than enrollment in a science major. 相似文献
