Stability of Core Language Skill from Early Childhood to Adolescence: A Latent Variable Approach

This four‐wave prospective longitudinal study evaluated stability of language in 324 children from early childhood to adolescence. Structural equation modeling supported loadings of multiple age‐appropriate multisource measures of child language on single‐factor core language skills at 20 months and 4, 10, and 14 years. Large stability coefficients (standardized indirect effect = .46) were obtained between language latent variables from early childhood to adolescence even when accounting for child nonverbal intelligence and social competence and maternal verbal intelligence, education, speech, and social desirability. Stability coefficients were similar for girls and boys. Stability of core language skill was stronger from 4 to 10 to 14 years than from 20 months to 4 years, so early intervention to improve lagging language is recommended.     

Teaching Lean Six Sigma within A Supply Chain Context: The Airplane Supply Chain Simulation

Lean six sigma is a management methodology that firms can employ to achieve substantial improvement in supply chain performance. However, few pedagogical exercises facilitate students’ use of a comprehensive set of lean six sigma principles within a supply chain context. We describe the Airplane Supply Chain Simulation that helps students understand how lean six sigma concepts may be leveraged to improve supply chain performance. The basis of this simulation is a four‐tier supply chain, consisting of suppliers (two tiers), a manufacturer, and a customer, that produces three models of paper airplanes to meet randomly distributed customer demand. In the first of three successive runs, a highly structured simulation is executed in which supply chain roles are well defined, material flows are convoluted, and a “push” production strategy is followed. The first simulation as the “current state” and, for the second and third simulation runs, challenge competing student teams to leverage lean six sigma concepts to develop a “future state” that enables the fulfillment of all customer orders at the lowest cost. Results based on statistical analyses of survey response data from 194 MBA students show that the Airplane Supply Chain Simulation is an effective participative, team‐based learning tool.     

A lifecycle model of the scientific communication process

A formal model of the scientific communication process is presented using the IDEF0 notation. The model provides a roadmap for policy discussions and further research. In comparison to earlier models it is more detailed and hierarchical, and includes more modelling constructs. It includes the whole communication value chain, from initial research to the assimilation of research results to everyday practice. Although the model treats both informal and formal communication, as well as the publishing of data, its focus is on modelling the publishing and indexing of traditional peer‐reviewed journal articles, and finding and retrieving them. New developments enabled by the Internet, such as open access journals and e‐print repositories, are also included.     

International Education and Training at Ecole Nationale des Ponts et Chausées/La Formation a l'international a l'Ecole Nationale des Ponts et Chaussées

The programme of the Département de la Formation Internationale at Ecole Nationale des Ponts et Chausées (ENPC) was created in 1981 to address the ever‐increasing international role of today's engineer in the scientific, economic and social spheres. Each year, 75 ENPC students spend at least 3 months abroad, mainly in Europe. ENPC has double degree programmes in engineering studies with three European partners in Germany and Spain: TU Munich and TU Berlin; Universidad Politécnica de Madrid. Twenty per cent of the student curriculum is devoted to language study; the students are required to study English plus one of the following languages: German, Spanish, Italian, Russian, Japanese or Chinese. French courses for foreign students are also provided. Language teaching aims to provide students not only with the linguistic skills necessary for communication, but also to make them more sensitive to other cultures as well as their own.     

Counselor Educators' Experiences Preparing Preservice School Counselors: A Phenomenological Study

The authors conducted a phenomenological study to explore the experiences of 32 school counselor educators preparing preservice school counselors. Analysis of data from 3 focus groups revealed 3 themes: breadth versus depth, balancing specialties and professor partiality, and preparation versus practice. These results highlight the need for collaboration across counseling specialties at the preservice level.     

Cultural diversity in science education through Novelization: Against the Epicization of science and cultural centralization

Science educators are confronted with the challenge to accommodate in their classes an increasing cultural and linguistic diversity that results from globalization. Challenged by the call to work towards valuing and keeping this diversity in the face of the canonical nature of school science discourse, we propose a new way of thinking about and investigating these problems. Drawing on the work of Mikhail Bakhtin, we articulate epicization and novelization as concepts that allow us to understand, respectively, the processes of (a) centralizing and homogenizing culture and language and (b) pluralizing culture and language. We present and analyze three examples that exhibit how existing mundane science education practices tend, by means of epicization, towards a unitary language and to cultural centralization. We then propose novelization as a way for thinking the opening up of science education by interacting with and incorporating alternative forms of knowing that arise from cultural diversity. © 2011 Wiley Periodicals, Inc.

Which do students prefer to evaluate their essays: Peers or computer program

The purpose of this study was to investigate problems and potentials of new technologies in English writing education. The effectiveness of automated writing evaluation (AWE) (MY Access) and of peer evaluation (PE) was compared. Twenty‐two English as a foreign language (EFL) learners in Taiwan participated in this study. They submitted their draft to MY Access, received feedback from this automated grading system and then made some revision. In addition to the AWE, they also had peer revision in writing class. Three issues, including how writers used the feedback from these two kinds of evaluation, what progress they made in writing and how they perceived these two kinds of evaluation, are discussed. Results showed that EFL learners in Taiwan generally opted for PE over AWE. These findings raise several relevant issues, including social learning, feedback strategies, computer anxiety and cultural impact.     

Defining the outcomes of teacher education: what's social justice got to do with it?

In the context of escalating criticism of university‐based teacher education across the world, a clear need exists for informed defence of the field and the profession as well as critical evaluation of both teacher education and schooling. This paper takes up the issue of the ‘outcomes question’ in this regard, arguing the case for a strong focus on social justice as the necessary complement to an ongoing concern with academic excellence and rigor. It argues the need for teacher educators and others to look closely at the different ways that educational outcomes are currently being defined and for these differences to be made more openly and widely available for criticism and discussion. The paper seeks to contribute to debate regarding the role and renewal of teacher education, in specific relation to widespread standards movements and the public good, and the conduct and governance of education more generally.     

Classroom justice: Perceptions of fairness as a predictor of student motivation,learning, and aggression

The present study examined the relationship between students’ perceptions of distributive and procedural justice in a college course and student motivation concerning the course, affective learning in the course, and aggression toward the course instructor. Although student perceptions of both distributive and procedural justice were positively correlated with student motivation and affective learning and negatively correlated with student aggression toward the course instructor, multiple regression analyses indicated that only perceptions of procedural justice predicted the three criterion variables at a statistically significant level while distributive justice perceptions did not. Implications and suggestions for future research in classroom justice are offered.
