Jewish Youth in Texas: Toward a Multi-Methodological Approach to Minority Identity

Qualitative and quantitative research methods are used to examine the religious and ethnic identity of youth attending a Jewish summer camp in Texas. A strong aspect of participants' Jewish identity is formulated in reaction to the surrounding Christian society, with which they negotiate a compromise to live relatively comfortably. The informal religious education and temporary community of the camp allow exploration of a proactive Jewish identity. A typology is developed with two sets of opposed concepts of identity: individual versus peoplehood and internal versus external. Sub-regions differentiate between fearful versus benevolent external identity and between psychological versus traditional internal identity.     

Improving Practice through Reflective Enquiry: confessions of a first‐time action researcher

A number of key constructs underpin educational action research. This paper focuses on the concept of ‘truth’ and by doing so hopes to highlight some debate in this area. In reflecting upon what ‘truth’ might mean to those involved in action research, I shall critically evaluate Thorndike's ‘Law of Effect’ and Bruner's ‘Three Forms of Representation’, and explain how these perspectives might help us find ‘the truth’ of an area under study and how they might inform the methodology of research. I shall close by suggesting that teacher‐researchers should allow for a constructivist approach in their action research methodology in order to help them in their sense‐making process.     

Genetic and environmental influences on writing and their relations to language and reading

Identical and fraternal twins (N?=?540, age 8 to 18 years) were tested on three different measures of writing (Woodcock-Johnson III Tests of Achievement—Writing Samples and Writing Fluency; Handwriting Copy from the Group Diagnostic Reading and Aptitude Achievement Tests), three different language skills (phonological awareness, rapid naming, and vocabulary), and three different reading skills (word recognition, spelling, and reading comprehension). Substantial genetic influence was found on two of the writing measures, writing samples and handwriting copy, and all of the language and reading measures. Shared environment influences were generally not significant, except for Vocabulary. Non-shared environment estimates, including measurement error, were significant for all variables. Genetic influences among the writing measures were significantly correlated (highest between the speeded measures writing fluency and handwriting copy), but there were also significant independent genetic influences between copy and samples and between fluency and samples. Genetic influences on writing were significantly correlated with genetic influences on all of the language and reading skills, but significant independent genetic influences were also found for copy and samples, whose genetic correlations were significantly less than 1.0 with the reading and language skills. The genetic correlations varied significantly in strength depending on the overlap between the writing, language, and reading task demands. We discuss implications of our results for education, limitations of the study, and new directions for research on writing and its relations to language and reading.     

The influence of golf shaft torque on clubhead kinematics and ball flight

ABSTRACT

The purpose of this study was to investigate the influence of shaft torque (torsional rigidity) on clubhead kinematics and the resulting flight of the ball. Two driver shafts with disparate levels of torque, but otherwise very similar properties, were tested by 40 right-handed golfers representing a range of abilities. Shaft deflection data as well as grip and clubhead kinematics were collected from 14 swings, with each shaft, for each golfer using an optical motion capture system. Ball flight and additional clubhead kinematics were collected using a Doppler radar launch monitor. At impact, the high torque shaft (HT) was associated with increased delivered loft (P = .028) and a more open face (P < .001) relative to the low torque shaft (LT). This resulted in the HT shaft being associated with a ball finishing position that was further right (P = .002). At the individual level, the change in face angle due solely to shaft deformation was significantly higher for the HT shaft for 25/40 participants. Although shaft twist was not directly measured, it was logically deduced using the collected data that these outcomes were the result of the HT being twisted more open relative to the LT shaft at impact.     

Combat science: the emergence of Operational Research in World War II

World War II became known as the "wizard war" because the cycles of developing countermeasures and counter-countermeasures to the weapons deployed by all sides drove rapid technological change. However, technological innovation was not the only contribution scientists made to the war effort. Through Operational Research (OR)--the scientific scrutiny of new weapons, their deployment and relative efficiency--scientists also influenced how warfare itself was conducted. This new scientific field emerged in the UK, where it helped to tighten the defense against the Luftwaffe. It quickly spread to other aspects of the military machine, improving both antisubmarine campaigns and bombing strategy. But although this analytical approach to warfare offered military commanders a factual basis on which to base difficult decisions and deal with tactical and strategic uncertainty, it was not without controversy. Indeed, several recommendations that came out of OR sparked disputes over the allocation of resources and strategic priorities.     

Extending the concept of publication: factbases and knowledgebases

The concept of a ‘publication’ no longer applies only to printed works; information technology has extended its application to several other types of works. This article describes a facility called the Common Knowledge Library that publishes modules of formally structured information representing facts and knowledge of various kinds. Publications of this new type have some characteristics in common with databases, and others in common with software modules; however, they also share some important characteristics with traditional publications. A framework for citation of previous work is important in order to provide an incentive for contributors of such modules. Peer review – the traditional method of quality assurance for scientific articles – must also be applied, although in a modified form, for fact and knowledge modules. The construction of the Common Knowledge Library is a cumulative process; new contributions are obtained by interpreting the contents of existing knowledge sources on the Internet, and the existing contents of the Library are an important resource for that interpretation process.     

dMath: a European project for the restatement of mathematics teaching

In this article the main characteristics of the dMath project are introduced. With the mathematical modules developed within this project a new tool is made available to the different users as a support of the teaching and learning of mathematics in the context of EHEA and of the Bologna declaration.     

Heterogeneity of student perceptions of the classroom climate: a latent profile approach

Student perceptions are a pivotal point of measurement for understanding why classroom learning environments are effective. Yet there is some evidence that student perceptions cannot be reliably aggregated at the classroom level and, instead, could represent idiosyncratic experiences of students. The present study examines whether heterogeneity in student perceptions of the classroom climate has implications for student achievement. We use data from 1428 seventh grade students in 75 mathematics classrooms from the Michigan Study of Adolescent and Life Transitions. Three dimensions of student perceptions of the classroom were measured: emotional support, autonomy support and performance focus. To obtain a measure of heterogeneity, we first reduced the data using latent profile analysis to describe profiles of students’ perceptions of the classroom. Next, we quantified the heterogeneity of student perceptions within classrooms using Simpson’s D. Classroom-level heterogeneity (Simpson’s D) of students’ perceptions was negatively associated with students’ mathematics achievement, even after controlling for individual- and classroom-level previous achievement, student’s prior perceptions and other variables. Findings suggest that measures of heterogeneity in student perceptions might be important for understanding classroom- and teacher-level effects on student outcomes.     

Education of the deaf in Australia and Norway: a comparative study of the interpretations and applications of inclusion

Inclusion is a term and process that is culturally, politically, medically, philosophically, and historically relative in its interpretations in the education of the deaf. The present study is a comparative analysis of two substantially different education systems for deaf students, those of Norway and Australia. The study objective was to elucidate the sources of some of these differences and to examine the interpretations and applications of inclusion that are inherent in the two countries' policies and practices, and in recent research evaluations. Significant differences exist in the national contexts and in the manner in which inclusion is understood and applied in Norway and Australia; the study reports on recent research examinations of inclusion in the two countries and finds that the transitions from policy to practice seem questionable.
