Assessing working memory capacity in a non-native language

The present studies directly test the usefulness of two English-language working memory capacity (WMC) assessments with two samples of students whose native language was not English. Participants completed two widely used complex span tasks, Reading Span (RSpan) and Operation Span (OSpan), in English. To determine whether the well-established relationship between WMC and Raven's Advanced Progressive Matrices (RAPM) would be observed when span tasks were not given in the native language of the participant, span scores were regressed against performance on the RAPM. Results indicated that while OSpan was a reliable and valid predictor of RAPM in non-native-English speakers, RSpan administered in English was not.     

The money trail: a new historiography for networks, patronage, and scientific careers

Money is everywhere in science. Yet historians have only rarely placed the money trail at the center of their analyses. The essays in this Focus section demonstrate that following the money offers a historiographical path for investigating a number of key issues across disciplinary boundaries in the nineteenth and twentieth centuries. Drawing on cases and materials relating to a number of scientific fields, including electrical engineering, aeronautics, agriculture, and paleontology, the essays examine the continuous role of money in industrial and military patronage, personal connections and networks, and spatial and geographical dimensions of science, as well as in relation to state funding and ownership. Together, the contributions demonstrate how following the money offers a way of overcoming hyperprofessionalism in the history of science.     

A NORWEGIAN OUT-OF-SCHOOL MATHEMATICS PROJECT’S INFLUENCE ON SECONDARY STUDENTS’ STEM MOTIVATION

Considerable resources are spent on initiatives aiming to increase achievement and participation in science, technology, engineering, and mathematics (STEM). Drawing on focus group interviews and a questionnaire study with participants in ENT3R, a Norwegian out-of-school mathematics program, we investigated why participants attended and stayed in this program and assessed how it influenced participants’ STEM motivation. The authors identified 3 aspects of ENT3R highlighted by the participants: The instructors provided good teaching, the instructors created a positive atmosphere, and the instructors engaged in interpersonal relationships. Moreover, drawing on the expectancy-value model, the authors found that ENT3R appeared to influence 5 factors in the model that are important for STEM motivation: expectation of success, interest–enjoyment value, attainment value, utility value, and cost. This study points to the importance of carefully recruited and trained instructors and of flexible, responsively designed extracurricular programs.     

Changes in students' understanding of evolution resulting from different curricular and instructional strategies

This study assessed students' learning of evolution by natural selection within four different sections of an introductory biology course. Each section used a different combination of curricular materials (either traditional or historically rich materials) and instruction (either paired problem solving or traditional lecture). Students in the study completed pre- and postintervention evolution tests. Students' responses were analyzed to create variables for both correct and alternative conceptions of evolution. Pretest and posttest data were used to create difference scores that were compared both within and between teaching sections. Pre-to-post gains were expected in the correct (Darwinian Conception) scores, while pre-to-post losses were expected in the Alternative Conception scores. Also, students in the experimental sections were expected to perform better than those in the traditional sections. Pretest-to-posttest differences within each section showed gains in correct conceptions but few reductions in alternative conceptions. Comparisons between sections support the use of the paired problem-solving instructional strategy in conjunction with the historically rich curriculum. © 1996 John Wiley & Sons, Inc.     

Interacting with People who have Severe Communication Problems: Ethical considerations

People who have severe speech and communication problems have difficulties making themselves heard both in everyday communications and society at large. In spite of the positive results which have followed the development of non-vocal intervention strategies, this group of people is at risk for being left out of the social common and being alienated. It is important to realise that one cannot do in the technical what one cannot do in the ethical. Unless both social interaction and intervention with people who have severe communication impairments are based on ethical reflection, the moral standards that are applied to this group may be lower than for other people. True communicative interaction depends on the acceptance that the other partner has something of value to communicate, even if the means for expressive communication are limited and the messages are vague and difficult to understand. A moral requirement for autonomy, that is, an equal footing or right to expression, places an ethical imperative on the more competent communication partner to strive to overcome the asymmetrical relationship and help the disabled person create authentic messages. Ethics is awareness based on the reflection on moral phenomena, grounded in the norms and values of the society and typically the result of discourse and co-constructive reflection, in the form of everyday discussions as well as of public philosophical scrutiny. Communication is a vehicle of reflection and discourse may be regarded as joined reflection. Thus, time for discourse in professional work may be a prerequisite for ethical practice.     

Cultural similarity and adjustment of expatriate academics

The findings of a number of recent empirical studies of business expatriates, using different samples and methodologies, seem to support the counter-intuitive proposition that cultural similarity may be as difficult to adjust to as cultural dissimilarity. However, it is not obvious that these results also are applicable to other groups of expatriates. To explore this eventuality, an electronic survey was directed towards expatriate academics in 34 universities in five European countries. For the purpose of this study, they were sorted into two groups, expatriate academics from EU countries and non-EU countries. Results showed that although the perceived cultural similarity between host and home country for the two groups of investigated respondents was different, there was neither any difference in their adjustment nor in the time it took for them to become proficient. Implications of these findings are discussed.     

Linking complex problem solving and general mental ability to career advancement: Does a transversal skill reveal incremental predictive validity?

Transversal skills, such as complex problem solving (CPS) are viewed as central twenty-first-century skills. Recent empirical findings have already supported the importance of CPS for early academic advancement. We wanted to determine whether CPS could also contribute to the understanding of career advancement later in life. Towards this end, we conducted a study (n = 245) at a large German automobile company in which we predicted career advancement and related criteria with CPS in addition to general mental ability (GMA). A computer-based assessment served as a measure of CPS. The dependent variables were the participants’ job level in accordance with the international standard classification for occupations (ISCO-08) and the number of professional training days as a proxy for lifelong learning efforts. The data were analysed using a structural equation modelling approach. CPS and GMA showed correlations (from .18 to .26, p < .01) with indicators of career advancement. All regression models showed good fit and indicated that CPS explained incremental variance in one of two indicators (β was .14 for trainings, p < .05). Our findings suggest an increment of CPS for predicting career advancement beyond GMA. Hence, CPS could complement GMA in methodologies for the study of professional development.     

Curricular decision-making among public sex educators

The content of sex education in government-funded schools in the USA varies dramatically and reflects its contested nature and goals. Drawing from 50 interviews with sex educators working in the public, government-funded school system in a Midwestern US state, this study explores the processes through which sex educators decide what and how to teach. Working from the theoretical framework of argument sphere theory, and, specifically, socio-scientific controversy, we find that sex educators often resolve the competing arguments they face through processes that we call deliberative conflation and deliberative co-optation. Deliberative conflation involves the use of criteria from one or more argumentative spheres to judge evidence appropriate to a different sphere. Deliberative co-optation involves the use of discourse practices from one sphere to make arguments actually grounded in another. Both of these processes enable the reconciliation of otherwise incommensurate arguments, but they do so in ways that foster unstable and ambiguous curricular decisions. Our findings provide guidance towards improving sex education and its attendant outcomes.     

A Shift to Inquiry: The Heart of Effective Teaching and Professional Development for the Twenty-First Century

This article explores how an experienced teacher navigates the demands of curriculum to implement her inquiry-centered teaching and learning philosophy, and how administrators along the way supported her during this change. Interviews with this classroom teacher surface suggestions for twenty-first-century professional development and support, including the development of equitable, intellectual, and trusting relationships between teachers and administrators, attitudes of curiosity and availability on the part of administrators, and the use of documentation to provide evidence and visibility of meaningful teaching and learning. This article invites teachers interested in change and administrators committed to supporting competent teachers to consider the strategies proposed.
