Urban school leadership for elementary science instruction: Identifying and activating resources in an undervalued school subject

This article explores school leadership for elementary school science teaching in an urban setting. We examine how school leaders bring resources together to enhance science instruction when there appear to be relatively few resources available for it. From our study of 13 Chicago elementary (K–8) schools' efforts to lead instructional change in mathematics, language arts, and science education, we show how resources for leading instruction are unequally distributed across subject areas. We also explore how over time leaders in one school successfully identified and activated resources for leading change in science education. The result has been a steady, although not always certain, development of science as an instructional area in the school. We argue that leading change in science education involves the identification and activation of material resources, the development of teachers' and school leaders' human capital, and the development and use of social capital. © 2001 John Wiley & Sons, Inc.

Effect of Guided Practice on Overhand-Throw Ball Velocities of Kindergarten Children

Abstract

Forty-five children from two intact kindergartens in one school were randomly assigned by sex to (a) an experimental group which received a movement program that included 120 min of guided practice in the overhand throw; or (b) a control group which received the same movement program but no exposure to the throw. A third group (N = 24), randomly selected by sex from a comparable school, received no movement program. Before and after the eight-week instructional period, ten trials of each child's overhand throw for force were filmed. Horizontal ball velocities were simultaneously recorded. ANOVAs on pre- and posttest ball velocities for each sex within each treatment group revealed no significant practice effect over ten trials (p > .05); thus, the trial mean was used as each subject's score. Two-way ANOVAs (treatment X sex) on the pre- and posttest data indicated no significant velocity differences (p > .05) between groups either before or after instruction. Boys had significantly greater velocities than girls (p < .05). Eight weeks of instruction that included 120 min of guided practice in the overarm throw did not significantly change the ball velocities of kindergarten children when compared to two groups with no formal throwing experience.     

Science Advising and Science Policy in Post-War West Germany: The example of the Deutscher Forschungsrat

The Deutscher Forschungsrat (GermanResearch Council) attempted to anchor scienceadvising and science policy in West Germanyafter the Second World War. Promoted by acircle of élite scientists, the councilaimed to establish institutions and mechanismscomparable to those in Great Britain, theUnited States, and other scientific powers.After a two-and-a-half year existence, iteventually failed. The reasons for its failure,some local, some global, display thedifficulties facing research policy in theearly years of the Federal Republic.     

A cross-cultural exploration of ‘wild’ in wilderness therapy: Canada,Norway and Australia

This paper addresses pluralistic understandings of wilderness in the context of wilderness therapy (WT). The term wilderness perpetuates a modern worldview of place that beyond ‘civilisation’ exists an environment defined by risk, fear and an unpredictable nature. WT utilises outdoor travel and living practices during therapeutic intervention and health promotion although empirical justification for its use of wilderness for therapy is not yet established. This paper provides three cultural perspectives on wild places in relation to WT. These national perspectives are informed by local practices, historical and societal understandings of wilderness and supported by related literature from Canada, Norway and Australia. The authors (1) illustrate a number of contemporary western assumptions about wilderness enshrined in the WT and outdoor adventure literature, (2) cautiously propose core purposes for using wild places for therapy and (3) encourage further development of WT practice and research within national, regional and even across organisational contexts.     

Conflict Resolution Patterns of Preschool Children With and Without Developmental Delays in Heterogeneous Playgroups

The conflict resolution patterns of preschool-age mildly developmentally delayed children were compared to those of older and younger groups of typically developing children matched on the basis of chronological age or developmental level. Children participated in short-term heterogeneous playgroups consisting of representatives from all three developmental status groups. Naturally occurring conflicts with peers in the form of extended directive episodes were assessed in terms of their frequency, purpose, strategies, and the way conflicts were resolved. Results revealed that mildly delayed children exhibit a more negative and less adaptive interaction style, even in comparison to typically developing children similar in developmental level. Special problems were apparent when younger typically developing and mildly delayed children engaged in conflict episodes, whereas typically developing older children were able to adjust and interact appropriately irrespective of their companions' developmental status. In addition, typically developing older children elicited a pattern in which other children were less demanding and negative, but more responsive, positive, and adaptive. The implications of developmental differences between younger and older typically developing children and the unique problems in conflict situations were discussed.     

Shifting learning goals: from competent tool use to participatory media spaces in the emergent design process

Recently, the relationship between identity and learning has come front and center in discussions about how to design successful learning environments for youth who struggle in mainstream institutions. In this essay, I explore the role identity development plays in constructing learning environments for traditionally marginalized youth. While I agree with DeGennaro and Brown on the importance of identity development for learning, I stretch the relationship between these two constructs in several ways: First, I will argue that how we define “technology” and what that means for marginalized youth, particularly those who are assumed to be victims of the “digital divide” is a crucial aspect of the design of successful digital learning environments. Second, I discuss how identity is represented in these digital learning spaces, and analyze how meaning is constructed in multimodal spaces such as websites. Finally, I reflect on DeGennaro and Brown’s notion of “emergent design,” as a positive contribution to design research, and propose the idea of incorporating youths’ already existing competencies into the emergent design process.

Children's friendship choices: Effects of school behavior

This study addresses three issues: (a) Which attributes characterize children's friendship choices? (b) Which show sex differences? (c) Which dimensions of teacher ratings of behavior contribute to peer selections? The issue of peer-teacher relatedness is addressed by obtaining peer nominations for certain attributes and independent measures of behavior that have been shown to be related to peer popularity. The results demonstrate that: (a) Peer acceptance is indexed by “Like to Sit By,” and this pattern is generally similar for boys and girls, with the exception of the dimension “Good at Games,” which characterizes boys' choosing peers. (b) The data on peer acceptance and rejection do not result in simple, bipolar dimensions, since these are not highly negatively correlated. (c) When peer nominations are assessed for possible teacher influences, an interesting sex difference emerges: girls prefer not to sit next to children whom their teachers rate as high in behavior problems.     

Insights into the value of a ‘stand‐alone’ course for sustainability education

Education for sustainability (EfS) is emerging as an urgent imperative and challenge for higher education. But what exactly does it mean to put sustainability into higher education? How do we bring sustainability themes into university curriculum, across the enormous diversity of academic disciplines? This paper describes the experience of teaching a large ‘stand‐alone’ EfS subject which sits within the professional contexts of the large first‐year cohort undertaking it. We describe the themes, architecture and approach to sustainability education taken in this course and evaluate the learning and assessment activities offered to students. We conclude with reflections on the student experience and feedback, which suggests that while academics build towards a deeply embedded sustainability ethic in higher education, specialist parallel courses have a valuable role to play in the transition to sustainable futures.     

Maternal Supportive Behavior,Cognitive Talk,and Desire/Emotion Talk at 24 Months: Distinct Factors and Differential Antecedents

Objective. Mental-state talk is an important aspect of parenting, but it is not clear whether this type of talk is structurally distinct from behavioral support or sensitivity. Although assessment of sensitive, supportive behavior captures a mother’s responses to her child’s needs, mental-state talk assesses a mother’s consideration of (and comments on) her child’s inner world. This study examined the structure and antecedents of mental-state talk, behavioral support, and sensitivity. Design. Data from the NICHD Study of Early Child Care and Youth Development were used, and mothering was assessed during a laboratory session when children were 24 months old (N = 1114). Results. Confirmatory factor analyses provided support for the hypothesized three-factor model, in which maternal supportive behavior, cognitive talk, and desire/emotion talk formed distinct factors. Furthermore, maternal depressive symptoms assessed at 1 and 6 months predicted less supportive behavior, whereas traditional parenting beliefs assessed at 1 month predicted lower levels of all three mothering outcomes. Conclusion. Maternal talk about mental states is a unique component of parenting, and cognitive talk is distinct from desire and emotion talk.
