Differential Grading Standards Revisited

The differential grading standards described by Goldman and Widawski (1976) exist in the same magnitude and in roughly the same order a decade later in a different kind of institution. Major fields that attract as majors students who score higher on SATs employ stricter grading standards. These differential grading standards serve to attenuate the correlation between SAT scores and grades, which is, even in highly selective institutions, substantial.     

A rule induction framework for the determination of representative learning design in skilled performance

Representative learning design provides a framework for the extent to which practice simulates key elements of a performance setting. Improving both the measurement and analysis of representative learning design would allow for the refinement of sports training environments that seek to replicate competition conditions and provide additional context to the evaluation of athlete performance. Using rule induction, this study aimed to develop working models for the determination of high frequency, representative events in Australian Rules football kicking. A sample of 9005 kicks from the 2015 Australian Football League season were categorised and analysed according to the following constraints: type of pressure, kick distance, possession source, time in possession, velocity and kick target. The Apriori algorithm was used to develop two models. The first consisted of 10 rules containing the most commonly occurring constraint sets occurring during the kick in AF, with support values ranging from 0.15 to 0.22. None of the rules contained more than three constraints and confidence values ranged from 0.63 to 0.84. The second model considered ineffective and effective kick outcomes and displayed 70% classification accuracy. This research provides a measurement approach to determine the degree of representativeness of sports practice and is directly applicable to various team sports.     

Laboratory versus field testing in cricket bowling: a review of current and past practice in modelling techniques

In cricket bowling, the reconstruction of elbow angle data is of utmost importance to the bowling versus throwing argument. This paper reviews system and modelling errors inherent in three-dimensional reconstruction processes with respect to the elbow extension tolerance set by the International Cricket Council. An understanding of these factors will enable more informed decisions about the choice of in-field versus laboratory testing in the calculation of elbow extension during bowling in cricket. Although there is a paucity of objective data related to in-field and laboratory testing, biomechanists must be guided by the greater accuracy of opto-reflective than video-based systems and so testing, at least for the present, should be conducted in a laboratory setting.     

Self-esteem and coping strategies among deaf students

Research studies on the determinants of self-esteem of deaf individuals often yield inconsistent findings. The current study assessed the effects on self-esteem of factors related to deafness, such as the means of communication at home and severity of hearing loss with hearing aid, as well as the coping styles that deaf people adopt to cope with everyday life in a hearing world. Data were collected among the deaf students of California State University, Northridge. Hierarchical regression modeling showed that identification with the Deaf community significantly contributed to positive self-esteem. Results also revealed that deaf students with greater degree of hearing loss and with bicultural skills that help them function in both the hearing and the Deaf community generally have higher self-esteem. Implications for further study are discussed.     

Thinking aloud together: A teacher’s semiotic mediation of a whole-class conversation about percents

How does classroom interaction support students’ apprenticeship into the ways of speaking, writing, and diagramming that constitute the practice of mathematics? We address this problem through an interpretative analysis of a whole-group conversation about alternative ways of solving a problem involving percent discounts that occurred in a sixth grade classroom. This research study draws upon Dewey’s theory of inquiry, Vygotsky’s cultural–historical psychology, Freudenthal’s realistic mathematics education, and Halliday’s systemic functional linguistics (SFL). From Freudenthal, we borrow the notions of mathematizing and guided reinvention—the former notion offers a view of mathematics as an activity of structuring subject matter and the latter one provides insights into the processes whereby mathematizing is learned and taught in the classroom. We glean from Dewey his view of reflective thinking as inquiry and the role that conversations may serve therein. We rely upon Vygotsky’s notions of a verbal thinking plane and a social phase of learning in order to reconsider the function of whole-class interaction in apprenticing students into mathematizing. Finally, SFL provides us with tools for explaining the choices of grammar and vocabulary students and teachers make as they realize meanings in whole-group conversations. Treating the selected whole-class conversation as a text, we focus our analysis on how this text came to mean what it did. Our central questions are as follows: What meanings were realized in the whole-class conversation by teacher and students and how were these meanings realized? How did the teacher’s lexico-grammatical choices guide the students’ choices? In addressing these questions, we advance an interpretation of the conversation as paradigmatic of students and teacher thinking aloud together about percents.     

The treasure house of a nation? Literary heritage,curriculum and devolution in Scotland and England in the twenty-first century

In January 2012, Scotland's First Minister Alex Salmond announced a radical measure that would see every Scottish school student study a Scottish text from a prescribed list. In 2010, Michael Gove announced that ‘Our literature is the best in the world’ and that every pupil should study particular authors. The ‘cultural heritage’ model of English is increasingly dismissed by teachers and students However, it is this ‘cultural heritage’ model which is preserved in the discourse of politicians. This paper explores the role that literary heritage texts play in the discourse of education policy in the context of devolution in twenty-first century Britain and considers the drivers and differences which can be seen in England and Scotland.     

What is Lesson Study?

This article addresses the conceptual question “what is lesson study?” as an issue that arises in the context of the globalisation of lesson study as a method for improving teaching and learning beyond its presumed origins in the Japanese education system. To what extent can adaptations of the method in different national settings be interpreted as faithful representations of its practically significant “critical features” in the country of origin? In order to address this question, the article begins by examining the comparative classroom research by Stigler and Hiebert that culminated in the publication of The Teaching Gap. This work is generally acknowledged to have been seminal for the global development of lesson study as a method for improving teaching and learning. Sponsored by the 1997 TIMMS testing programme, the research sought to explain pronounced differences in measured educational attainment between students of all ages in Japan, and the US and Germany. In the process Stigler and Hiebert discovered the extensive use of lesson study in Japanese primary schools as a school‐based research method for securing consistency between learning goals and teaching methods. In doing so, they identified six principles which underpinned the method and pinpointed its practical significance. In this article, the author claims that the principles identified by Stigler and Hiebert can be used as a framework for assessing adaptations of lesson study in the context of globalisation, and connecting it to related methodological ideas that are internationally circulating. In particular, the author stresses links between lesson study, the tradition of classroom action research forged by Lawrence Stenhouse and his colleagues at the University of East Anglia, UK and the theory of variation developed in Sweden and Hong Kong by Ference Marton, Lo Mun Ling and others. Such links can deepen a theoretical understanding of “lesson study” and safe‐guard it against a “cherry‐picking” approach to its implementation in a context of globalisation. The article particularly highlights the importance of understanding the ways in which the organisational cultures of schooling in many countries shape and distort the implementation of lesson study. It argues for the greater involvement of school leaders and administrators in a form of second‐order action research aimed at transforming the organisational context of teachers’ work in classrooms and creating more space for them to spend less time as test data managers and more time as lesson researchers in accordance with the six principles outlined.     

The University Experiences of Students with Learning Disabilities

To explore the university experiences of students with learning disabilities (LD), 63,802 responses to the 2014 Student Experience in the Research University Survey were analyzed. Compared to other students, those with self‐reported LD (5.96 percent) had difficulty with assignments and had more obstacles caused by nonacademic responsibilities and imposed by their skill levels. Students with self‐reported LD sensed more bias toward people with disabilities on campus, and they were less satisfied with their overall experience. Interactions between disability status and age suggested even more challenges for older students who self‐reported LD. Approximately one‐third of students who self‐reported LD received accommodations. The rate of accommodations was higher among individuals who were wealthy, who lived alone, and who were out‐of‐state students. Compared to students who self‐reported LD but reported no accommodations, those with accommodations had more contact with faculty and less difficulty with assignments.
