The Cognitive Predictors of Computational Skill with Whole versus Rational Numbers: An Exploratory Study

The purpose of the present study was to explore the 3rd-grade cognitive predictors of 5th-grade computational skill with rational numbers and how those are similar to and different from the cognitive predictors of whole-number computational skill. Students (n = 688) were assessed on incoming whole-number calculation skill, language, nonverbal reasoning, concept formation, processing speed, and working memory in the fall of 3rd grade. Students were followed longitudinally and assessed on calculation skill with whole numbers and with rational numbers in the spring of 5th grade. The unique predictors of skill with whole-number computation were incoming whole-number calculation skill, nonverbal reasoning, concept formation, and working memory (numerical executive control). In addition to these cognitive abilities, language emerged as a unique predictor of rational-number computational skill.     

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.     

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.     

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.     

In support of teachers’ learning: specifying and contextualising teacher inquiry as professional practice

Drawing upon research into a case study of teacher inquiry in one school in Queensland, Australia, recent theorising into professional practice, and relevant literature on teachers’ learning, this article reveals the complexity and particularity of teacher inquiry processes in support of teachers’ learning. Specifically, the research reveals how particular actions, dialogue, and relationships collectively constitute a practice of teacher inquiry which seeks to promote substantive teacher-led learning. The research draws upon a group of Year 5 teachers engaged in collective inquiry into their work in what was described as an “Inquiry Cycle” approach in a school in northern Queensland, during a period of support for substantial curriculum reform. The research reveals the Inquiry Cycle approach as characterised by specific actions, dialogue, and relationships – “doings,” “sayings,” and “relatings” – productive of the development of a learning culture focused on significant curriculum reform; overt support for whole-school “explicit” approaches to teachers’ pedagogies; and active/robust critique of data-focused assessment processes. The research reveals necessary texture and detail in support of teachers’ learning, and the specific circumstances and contextual “arrangements” that help constitute this learning.     

Understanding Categorical Hierarchies: The Earliest Levels of Skill

2 categorization skills necessary for understanding hierarchies are the ability to form categories at different levels of generality and the ability to include the same objects into multiple categories. 2-year-olds appear to have the first skill, but some theoretical and empirical work suggests that the second may be a later acquisition. Yet, in 3 studies, 2- and 3-year-olds applied familiar basic level and superordinate labels to the same objects, even when reminded of basic labels before being tested with superordinates. They did not reserve superordinates for objects with unfamiliar basic level names (Study 2), and they were willing to apply superordinates to objects presented singly rather than in groups (Study 3). Thus, contrary to the implications of some previous work, 2- and 3-year-olds appear to have both of the categorization skills necessary for forming categorical hierarchies.     

Computer conferencing: A new medium for investigating issues in gender and learning

Claims have been made that computer mediated communication (CMC) is a potentially highly participatory and democratic medium because it reduces the requirement to interrupt or wait your turn to speak. Such aspects of discussion have been shown to be relevant to differences in male and female participation in group discussions. In general, men have been found to take more turns and to speak longer than women in mixed sex groups. Men are also said to characteristically speak about things, take centre stage and give opinions. Women on the other hand are more likely to emphasis people rather than things, and to build and maintain relations in the way they talk. These two styles have been described as report talk of men and rapport talk of women.In this paper we describe some preliminary findings on the impact of using CMC and its effect on traditional gender participation differences. We look first at turn taking by men and women in computer conferences, and then how women in particular experience differences in the kind of contributions made to the conferences by men and women. Finally, we look at the actual contributions made by men and women and the extent they differ from each other.     

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).     

Audio teleconferencing and the adult learner: Strategies for effective practice

Abstract

Audio teleconferencing is a distance learning delivery system that has often been overlooked by educational institutions and other organizations. However, the trend toward adoption of “high‐end” (and high cost) delivery systems is giving way to a new trend toward appropriate selection of a delivery system based on course content, course design, and intended audience. This article takes a close look at audio teleconferencing as a viable option for many distance learning situations, discusses the importance of the audio component in distance learning, and suggests management and delivery strategies for organizations considering this medium.
