Comments on Where the Creativity Research Has Been and Where Is It Going

This Commentary examines where the creativity research has been and where it is going. They key points include evolving definitions of creativity, interdisciplinarity in the creativity research, divergent thinking as a reliable index of creative potential, improvements in testing, the impact of technology, the inclusion of political, moral, and everyday creativity in the research, the use of semantic networks and conceptual maps, the creative economy, and the need to extricate personal creativity from social recognition.     

The Genealogy of “Empirical Post-structuralist” STS,Retold in Two Conjunctures: The Legacy of Hegel and Althusser

Recent discussions in science and technology studies (STS) about the risks of science and technology have led to political economy occupying centre stage. Closely related to political economy as a field of investigation are a number of overarching concepts, such as class, capitalism and interest. However, reliance on such concepts is rejected in post-Actor Network Theory STS. This stand-off over overarching categories can be traced back to two conjuntures in the genealogy of STS. First, the influence of Hegel and his concept of “totality”; and second, the influence from anti-hegelian French epistemology with its celebration of the opposite concept, that of “multiplicity”.     

集体记忆中的协作促进及其原因

摘 要 协作促进是指先前协作提取的经验对后续的个人提取具有积极影响。为了探讨协作促进产生的基本条件及其原因,本研究通过两个实验分别考察了小组的人数和回忆方式对协作促进的影响以及他人再现和交叉线索对协作促进的贡献。结果表明：无论小组的大小为2人组、3人组还是4人组,回忆方式为轮流回忆还是自由回忆均能产生协作促进,且轮流回忆的协作促进量要高于自由回忆的协作促进量;他人再现对协作促进的贡献大于交叉线索。这说明协作促进是一个稳定的现象,其主要原因是他人再现的作用。     

A systematic evaluation of token economies as a classroom management tool for students with challenging behavior

A two-part systematic review was undertaken to assess the effectiveness of token economies in increasing rates of appropriate classroom behavior for students demonstrating behavioral difficulties. The first part of the review utilized the recently published What Works Clearinghouse (WWC) standards for evaluating single-subject research to determine the extent to which eligible studies demonstrated sufficient evidence to classify the token economy as an evidence-based practice. The second part of the review employed meta-analytic techniques across four different types of effect sizes to evaluate the quantitative strength of the findings. Methodological strengths and weaknesses across the studies were systematically investigated. Results indicated that the extant research on token economies does not provide sufficient evidence to be deemed best-practice based on the WWC criteria.     

The effects of session length on demand functions generated using FR schedules

In comparing open and closed economies, researchers often arrange shorter sessions under the former condition than under the latter. Several studies indicate that session length per se can affect performance and there are some data that indicate that this variable can influence demand functions. To provide further data, the present study exposed domestic hens to series of increasing fixed-ratio schedules with the length of the open-economy sessions varied over 10, 40, 60, and 120 min. Session time affected the total-session response rates and pause lengths. The shortest session gave the greatest response rates and shortest pauses and the longest gave the lowest response rates and longest pauses. The total-session demand functions also changed with session length: The shortest session gave steeper initial slopes (i.e., the functions were more elastic at small ratios) and smaller rates of change of elasticity than the longest session. Response rates, pauses, and demand functions were, however, similar for equivalent periods of responding taken from within sessions of different overall lengths (e.g., total-session data for 10-min sessions and the data for the first 10 min of 120-min sessions). These findings suggest that differences in session length can confound the results of studies comparing open and closed economies when those economies are arranged in sessions that differ substantially in length, hence data for equivalent-length periods of responding, rather than total-session data, should be of primary interest under these conditions.     

Quality of maternal thinking and mother-child interaction in at-risk contexts

This study investigates how the maternal level of perspectivistic reasoning and the level of socialization goals in the representation of their actions are related to the quality of mother-child behaviors as well as to the expert ratings on maternal practices in at-risk contexts. It also investigated whether there is any direct link between mother and child behaviors and expert ratings. A sample of 75 mothers of children between 8 and 12 years old reported on their level of perspectivistic reasoning and were characterized by the social workers of municipal services as being coercive, neglectful or meeting their child's needs. Interactions during a collaborative task were observed to obtain information on level of socialization goals and mother-child behaviors. Structural equation models showed that mothers' higher levels of perspectivism and higher levels of socialization goals positively predicted the mother's and child's sensitivity and active involvement in the task and negatively predicted avoidance and passivity. Higher levels of perspectivism consistently predicted experts' views on maternal practices. However, only mother's avoidance predicted negatively expert ratings on coercion practice, indicating that expert views were mostly derived from the mothers' perspective on their child. The implications of these results for parental assessment and intervention programs are discussed.     

Evidence-based mental health interventions for traumatized youth: a statewide dissemination project

Psychological trauma in childhood has been shown to increase a variety of psychological disturbances and psychiatric disorders. Although evidence-based treatments for children who have been traumatized exist, they are infrequently used by clinicians treating children. The present paper describes the creation of the Treatment Collaborative for Traumatized Youth (TCTY) which is a statewide partnership in North Dakota designed to disseminate efficacious treatments for traumatized children and monitor outcomes across a broad, rural, geographic expanse. The paper reviews the dissemination strategy developed by the TCTY, reports outcomes regarding both clinicians and child participants, and highlights problems identified in the project and solutions that were generated.     

Uncommon Schools: Stanley Cavell and the Teaching of Walden

Thoreau’s Walden is a text that has been misinterpreted in various ways, one consequence of which is a failure to appreciate its significance as a perfectionist and visionary text for education. This paper explores aspects of what might be called its teaching, especially via the kind of teaching that is offered by Stanley Cavell’s commentary, The Senses of Walden. Walden is considered especially in the light of its conception of language as the “father-tongue” and of the ideas of continual rebirth and departure that are associated with this. References to teaching and learning abound in the book, but it is Thoreau’s specific reference to the need for “uncommon schools” that provides a focus for the present discussion. Paul Standish is Professor of Philosophy of Education at the University of Sheffield. His recent books include The Blackwell Guide to Philosophy of Education (2003), co-edited with Nigel Blake, Paul Smeyers and Richard Smith. He is Editor of the Journal of Philosophy of Education and Co-editor of the online Encyclopaedia of Philosophy of Education.     

The effect of students’ roles on the establishment of shared knowledge during collaborative problem solving: a case study from the field of mathematics

According to role theory each participant in a peer interaction performs a specific role in order to maintain his/her face. The aim of the present study was to examine whether the roles performed during collaborative problem solving affect the establishment of shared mathematical knowledge. The participants of our study were 40 student teachers who worked in dyads to solve three mathematical problems. The categorization of the roles performed and the analysis of their effect in the establishment of shared knowledge led us to the conclusion that certain role combinations enhance while others hinder the establishment of shared mathematical knowledge. An earlier version of this paper was presented at the 28th Annual Conference of the International Group for the Psychology of Mathematics Education (PME 28), held in Bergen, Norway in 2004.
