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.

Text Comprehension and Oral Language as Predictors of Word-Problem Solving: Insights into Word-Problem Solving as a Form of Text Comprehension

This study was designed to deepen insights on whether word-problem (WP) solving is a form of text comprehension (TC) and on the role of language in WPs. A sample of 325 second graders, representing high, average, and low reading and math performance, was assessed on (a) start-of-year TC, WP skill, language, nonlinguistic reasoning, working memory, and foundational skill (word identification, arithmetic) and (b) year-end WP solving, WP-language processing (understanding WP statements, without calculation demands), and calculations. Multivariate, multilevel path analysis, accounting for classroom and school effects, indicated that TC was a significant and comparably strong predictor of all outcomes. Start-of-year language was a significantly stronger predictor of both year-end WP outcomes than of calculations, whereas start-of-year arithmetic was a significantly stronger predictor of calculations than of either WP measure. Implications are discussed in terms of WP solving as a form of TC and a theoretically coordinated approach, focused on language, for addressing TC and WP-solving instruction.     

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     

Challenges and Achievements: Teaching Shakespeare''''s Sonnet 34 to a Third Year "English Literature" Class

In the course offerings to students in the Foreign Languages College here atGuangxi Teachers'University,I had noted what was in my opinion an overemphasis onprose at the expense of poetry;and also a dearth of courses thatwentdeeply into a singlesubject,period,or writer.In place of this,courses tended to be survey,background,criticism,or history.After discussing this with my colleague,Professor Zheng Shuning,here at the Uni-versity,I determined to take a different approach in my Fall Term,…     

Critical action learning – rituals and reflective spaces

This paper is written to outline our ideas on rituals and reflective places and how this thinking has emerged through our writing, facilitation and reflections around critical action learning and critical leadership. We attempt to show the conceptual framework that underpins our vision of Critical Leadership and how out of this work we have begun to develop new action learning techniques which we believe help to make the action learning we teach and practise, more critical. In describing these concepts of criticality we consider the tripartite elements of each of the three concepts we call Critical Leadership. That is ‘knowing, being, doing’; ‘space, place and pace’ and ‘thinking, feeling, willing’. We then go on to demonstrate how these three concepts helped us to shape our new action learning technique entitled ‘The Coliseum’. We believe that this new action learning technique enhances the likelihood of critical action learning taking place by underscoring key elements such as encouraging feedback, initiating deep listening, promoting challenge and, perhaps, in the end, precipitating enlightenment.     

Conditioned cardiac and behavioral response topography to an olfactory CS dissociates with age

Conditioned cardiac and behavioral responses to an olfactory stimulus (CS) paired with electric shock (US) were studied in 16-, 23-, and 75-day-old rats. Heart rate and behavior were recorded during a single 15-trial training session in which a 10-sec olfactory stimulus (amyl acetate) was either paired or explicitly unpaired with the US. In the preweanling rats, the conditioned cardiac response consisted of anincrease in heart rate (tachycardia) and a slight increase in investigatory behaviors. In contrast, the conditioned cardiac response in the adult rats consisted of adecrease in heart rate (bradycardia) and a striking increase in behavioral immobility (freezing). The 23-day-old rats showed a dichotomous pattern of responding; some showed preweanling-like conditioned responses and some showed adultlike responses. Developmental changes in neural organization and degree of learning are discussed as possible determinants of the transition from infant to adult modes of responding.     

Gaps in Mind: Problems in environmental knowledge-behaviour modelling research

For decades, researchers in the social sciences and in education have sought to understand and map the factors that lead people to move (or to fail to move) from environmental knowledge to 'pro-environmental behaviour'. In this article, we explore some conceptual, epistemological, methodological and practical 'gaps' that seem to reproduce themselves in successive instantiations of this quest. The purpose of this article is to help build the critical perspective that comes with problematizing the very project of knowledge-behaviour modelling, identifying the positivistic residues still present in the enterprise, and suggesting that modelling may be more useful in domains of greater scale. Focusing on the 'Mind Gap' model developed by Kollmus and Agyeman (2002), we discuss the 'gap' between contemporary educational research and knowledge-behaviour modelling research that is the cumulative effect of (1) the critical thinking - 'behaviour change' gap; (2) the 'reflective practitioner - 'researcher as authority' gap; (3) the two literatures gap; (4) the conscious - non-conscious gap (tied to reason and habit in moral agency); (5) the direct action - indirect action gap (tied to privatizing environmental morality); (6) the gender gap; and (7) the internal - external gap (tied to ignoring the complexity of moral agency and cultural identity).     

Preparing novice teachers to develop basic reading and spelling skills in children

This study examined the word-structure knowledge of novice teachers and the progress of children tutored by a subgroup of the teachers. Teachers’ word-structure knowledge was assessed using three tasks: graphophonemic segmentation, classification of pseudowords by syllable type, and classification of real words as phonetically regular or irregular. Tutored children were assessed on several measures of basic reading and spelling skills. Novice teachers who received word-structure instruction outperformed a comparison group of teachers in word-structure knowledge at post-test. Tutored children improved significantly from pre-test to post-test on all assessments. Teachers’ post-test knowledge on the graphophonemic segmentation and irregular words tasks correlated significantly with tutored children’s progress in decoding phonetically regular words; error analyses indicated links between teachers’ patterns of word-structure knowledge and children’s patterns of decoding progress. The study suggests that word-structure knowledge is important to effective teaching of word decoding and underscores the need to include this information in teacher preparation.     

Home and Parental Influences on the Achievement of Lower Primary School Children in Singapore

This study investigated the effects of home environment and parental involvement in the achievement of pupils in the lower primary classes in nine schools found in four zones in Singapore. In total, 3,759 pupils and their parents participated in the study. The study was designed to answer four main questions relating to the effects of the home environment (SES, time engaged in television viewing, reading, school work and ethnicity of parents) and parental involvement in the children's school work and in other school matters. The findings indicated that significant differences in achievement were found for all combinations of SES categories and between most ethnic groups. A higher percentage of high-achieving pupils spent more time on television viewing, reading and school work. Parents of high-achieving children were more anxious about maximising every opportunity for their children including those not directly related to school work.
