This work addresses the subject of mathematics education at secondary schools from a current and stimulating point of view intimately related to computational science. Cryptology is a captivating way of introducing into the classroom different mathematical subjects such as functions, matrices, modular arithmetic, combinatorics, equations,…

New capabilities in "TinkerPlots 2.0" supported the conceptual development of fifth- and sixth-grade students as they pursued several weeks of instruction that emphasized data modeling. The instruction highlighted links between data analysis, chance, and modeling in the context of describing and explaining the distributions of measures that result…

Background: Bullying has usefully been described as demonstrations of the norms of young people's social groups, outlawing and punishing those who do not conform. The way a person appraises bullying strongly influences the coping process, how the person reacts emotionally and bystander behaviour. A social-psychological perspective was used to…

A sample of 423 Swiss job entrants reported major change in general, as well as positive and negative work experiences one, two, and four years after finishing vocational training. Qualitative data analysis showed change in responsibility, increase in decision latitude, acquisition of new status (professional work status, full team member status),…

This paper presents selected findings from an ESRC-funded research project examining the choices and occupational aspirations of 59 students approaching the end of their compulsory schooling. It concentrates on the development of a choice model conceptualising the decisionmaking processes of the young people involved in the study, whilst avoiding…

Reform initiatives such as "Science for All Americans" (AAA, 1989) and "National Science Education Standards" (NRC, 1996) argue for making science accessible to all children regardless of age, sex, cultural and/or ethic background, and disabilities. One of the most popular and prevailing phrases highlighting science education reform in the last…

The American Recovery and Reinvestment Act (ARRA) provides several funding opportunities that can assist states in designing, developing, and implementing statewide education longitudinal data systems. These new and enhanced information systems will enable states to track student progress within and across the secondary and postsecondary education…

The ability to predict a student's performance could be useful in a great number of different ways associated with university-level learning. In this paper, a grammar guided genetic programming algorithm, G3P-MI, has been applied to predict if the student will fail or pass a certain course and identifies activities to promote learning in a…

The purpose of this study was to explore the use of action research as a framework to investigate cooperative learning and tactical games as instructional models in physical education (PE). The teacher/researcher taught a tennis unit using a combination of Cooperative Learning and Teaching Games for Understanding to three classes of boys aged…

In the mid-1960s, social scientists Barney Glaser and Anselm Strauss developed grounded theory as a systematic and rigorous method of qualitative data analysis leading to "the discovery of theory from data." In grounded theory, the researcher applies a set of coding procedures to the data until a provisional theory emerges inductively.…

Unstable, and potentially invalid, variance component estimates may result from using only a limited portion of available data from operational performance assessments. However, missing observations are common in these settings because of the nature of the assessment design. This paper describes a procedure for overcoming the computational and…

This report presents findings on the role of tuition in financing higher education and as payment by students and parents. The content is organized into 11 chapters grouped into six parts. Part 1 is an enrollment profile of students who opt to attend college. Topics covered include starting conditions, such as student academic skills, family…

The Steering Committee of the National Postsecondary Education Cooperative established a Unit Record versus Aggregate Data Working Group in 1996 to identify and assess data sharing methods that are needed to advance the understanding of how postsecondary students are served, and with what outcomes. Most mandated record sharing has been through…

The assessment of dimensionality of data is important to item response theory (IRT) modelling and other multidimensional data analysis techniques. The fact that the parameters from the factor analysis formulation for dichotomous data can be expressed in terms of the parameters in the multidimensional IRT model suggests that the assessment of the…

Research with older persons suffering from physical illness presents numerous challenges to gerontologists. Issues of conceptualization pertaining to the definition of illness, its location in the research paradigm, and the context in which illness occurs must be addressed prior to dealing with methodological problems. Access to physically ill…
