Understanding conceptual change: connecting and questioning

We engage in a metalogue based on eight papers in this issue of Cultural Studies of Science Education that review the state of conceptual change research and its possible affect on the teaching and learning of science. Our discussion addresses three aspects of conceptual change research: theoretical, methodological, and practical, as we discuss conceptual change research in light of our experiences as science educators. Finally, we examine the implications of conceptual change research for the teachers and students with whom we work.

Individual differences among undergraduate women in methods of coping with stressful events: the impact of cumulative childhood stressors and abuse

OBJECTIVE: The purpose of the current study was to determine if a history of greater exposure to different types of adverse and/or abusive experiences in childhood would influence coping strategies used by undergraduate women to deal with new stressful events in young adulthood. METHOD: A sample of 828 women undergraduates from a New England state university participated in this questionnaire study. Disengagement and engagement coping strategies used in response to recent stressors were compared in groups who had none, one, two, or three or more types of adverse and/or abusive childhood experiences (sexual abuse, physical abuse, witnessing domestic violence, having an alcoholic parent, and parental rejection). RESULTS: There was an increased reliance on disengagement methods of coping (wishful thinking, problem avoidance, social withdrawal, and self-criticism) as a function of more extensive child abuse histories. Engagement methods of coping (problem solving, cognitive restructuring, social support, and express-emotions), however, did not show a corresponding decrease as a function of increased exposure to different types of childhood stressors and/or abuse. CONCLUSIONS: This study demonstrates that undergraduate women with cumulative adverse and/or abusive childhood histories are particularly at-risk of relying on maladaptive disengagement coping strategies to deal with various new stressors later in life.     

Preschoolers' Emotional Control in the Disappointment Paradigm and Its Relation to Temperament, Emotional Knowledge, and Family Expressiveness

The present research evaluated a conceptual model that links temperament, emotional knowledge, and family expressiveness to preschoolers' emotion regulation ability. The emotional understanding of 82 preschoolers was assessed with 2 separate tasks. After the second emotional knowledge task, the children were presented a "disappointing" prize, and their facial displays of positive and negative affect were recorded. The children and their mothers also participated in a game designed to elicit maternal expressive behavior. Mothers provided information about the preschoolers' temperament and about the frequency of positive and negative affect expressed within their families Results indicated that children's positive displays when presented the "disappointing" prize were inversely related to the temperamental dimension of emotional intensity and positively associated with children's understanding of emotion. Maternal reports of sadness within the family were inversely related to children's positive affective displays. Children's negative emotional displays in the disappointment situation were inversely related to observed maternal positive emotion. The findings from this study give greater specification to the unique and joint contributions of temperament, emotional knowledge, and family expressiveness in predicting preschoolers' expressive control of emotion.     

The nature of reader ability differences in lexical access

Can good and poor readers be differentiated by their use of word-naming and lexical access codes? Poor readers experience extreme difficulty in decoding nonsense words, indicating that they cannot use the spelling to sound rules which underlie the indirect phonological route to word pronunciation. However, recent evidence suggests that poor readers do use a phonological route for lexical access in word and picture naming tasks which rely upon the production of a phonological code. Is this also true of other tasks, which are not dependent upon phonological representation? Two such tasks are described in the present study: one involving picture-word interference, and the other involving a lexical decision paradigm. Results showed that poor readers do use a phonological route to lexical access independent of task demand. A review of findings in this area to date shows several inconsistencies, and an attempt is made to resolve these by drawing on Stanovich's (1980) interactive-compensatory model of reading.     

The Outcome of a Social Cognitive Training for Mainstream Adolescents with Social Communication Deficits in a Chinese Community

The use of cognitive-based strategies for improving social communication behaviours for individuals who have solid language and cognition is an important question. This study investigated the outcome of teaching Social Thinking^®, a framework based in social-cognition, to Chinese adolescents with social communication deficits. Thirty-nine students (33 with Autism Spectrum Disorders and six without), ranging in age from 12 to 15 years with social communication deficits, participated in a 12-week intervention. Students’ pre- and post-intervention social behaviours were measured by six aspects of the Social Thinking-ILAUGH Scale involving 115 familiar raters. Students showed significant improvement in all the six subscales of the Social Thinking-ILAUGH except humour after training. Agreements on ratings among parents and school personnel were satisfactory. A framework based in social cognitive strategies, with appropriate linguistic and cultural adaptations, appears to be a promising tool for Chinese adolescents with social learning issues. Social behaviours improved across school and home settings as noted by groups of raters familiar with the students.     

In search of pedagogical content knowledge in science: Developing ways of articulating and documenting professional practice

This study examines the development of ways of documenting and portraying science teachers' pedagogical content knowledge (PCK). As a result of a longitudinal study into science teachers' pedagogical content knowledge, a method is developed for capturing and portraying PCK that comprises two important elements. The first is linked to the particular science content, termed Content Representation (CoRe), and the second is linked to teaching practice, termed Professional and Pedagogical experience Repertoire (PaP‐eR). Through this approach new understandings of PCK emerge that are of interest in terms of both academic (knowledge building about PCK) and teaching perspectives. This study includes a full CoRe and one PaP‐eR and fully demonstrates how these two elements interact to begin to portray science teachers' pedagogical content knowledge. © 2004 Wiley Periodicals, Inc.

Being chimaera: a monstrous identity for SoTL academics

Lurking on the fringes of university culture are academic identities that do not fit into the usual disciplinary communities. Aiming to explore the experience of ‘being academic’ when not linked directly to a discipline, this paper examines the stories of a diverse group of SoTL scholars who work in a centralised multi-campus academic skills support centre in an Australian university. Framed as group auto-ethnography, the paper inquires into the everyday experience of these academics through narrative analysis of multiple first-person accounts and makes apparent the monstrousness of de-affiliated academic identities. Despite diverse disciplinary backgrounds, the author-participants found that they now shared a tripartite academic identity formed through the negotiation of three roles: the teacher, the disciplinarian, and the educational researcher. Using the chimaera, a mythical three-headed monster as an organising metaphor, this paper aims to provide agency and visibility for often under-represented and unacknowledged academic identities.     

Underprivileged urban mothers' perspectives on science

The purpose of this article is to report our findings from a qualitative study intended to develop our understandings of how inner‐city mothers perceive science. Using qualitative methodologies, our analysis reveals that the mothers' perceptions can be grouped into four categories: perceptions of science as (a) schoolwork/knowledge, (b) fun projects, (c) a tool for maintaining the home and family, and (d) an untouchable domain. After we present these categories we compare our findings across categories to argue that those mothers who had spent time doing science with their children were more likely to have a more personal, dynamic, and inquiry‐based view of science. We also argue that mothers' perceptions of science were more dynamic when they spoke about situations and contexts that were familiar to them, such as food, nutrition, and child care. We conclude the article with a discussion of the implications our findings have for science education reform. © 2001 John Wiley & Sons, Inc. J Res Sci Teach 38: 688–711, 2001     

Conditioned suppression and discriminative control of behavior

Rats were trained on a multiple variable-interval extinction schedule of reinforcement. The effects of a stimulus which preceded an unavoidable shock were assessed when it was superimposed on both components of the schedule or on VI components only. In general, VI responding was suppressed during the preshock stimulus. There was no evidence for any increase in responding during extinction components either generally or differentially during the preshock stimulus. These findings fail to support an earlier suggestion that a preshock stimulus may impair discrimination performances.
