Children's skill in making predictions and their understanding of what predicting means: A developmental study

The purpose of this study was to describe the development of elementary students' skill in making predictions and of their understanding of what predicting means. The study involved observing and assessing the performance of 167 children on the Physical Manipulation Test (PMT), a test involving the manipulation of science materials and equipment. Children were interviewed about what they understand predicting to mean, how they use it at school and at home, and why they think it is important. For each of the seven topics tested, even the youngest children were able to offer predictions. Accuracy varied with the topic, increasing between Grades 1 and 4 and leveling off after that. The increase in skill involved children's growing ability to attend to patterns discerned through their own observations. Four levels in the development of predicting skill, as it relates to particular topics, are described. Children's understanding of predicting showed steady improvement through Grade 6. Children's awareness of their use of predicting at school and at home, and their ability to explain the importance of predicting, also increased through Grades 1 to 6, with a spurt at Grade 4. Children understood predicting to be an internal process in which one uses knowledge to anticipate a future event; they regarded predicting as an important way of being intellectually involved with the world.     

Distributed leadership with the aim of ‘reculturing’: a departmental case study

This article considers a secondary science department that has, since 2000, developed distributed leadership as a form of human capacity building. Using a longitudinal ethnographic case study allowed us to consider how distributed leadership can be nurtured and developed in a department. Our analysis centres on two key issues: the nature and pattern of distributed leadership practices and the continuity that provides coherence to those practices. From our analysis, there appear to be two major conclusions. The first of these is the need for administrators to be purposeful in the appointments that they make to formal leadership positions. To enact distributed leadership practices requires leaders who can exercise both formal power and influence. The second conclusion relates to the time required for continuity of leadership practices to give rise to changes that lead to teachers managing the teaching and learning programme.     

Herrnstein’s equation for the rates of responding during concurrent schedules

A modification of the nonlinear curve-fitting procedure proposed by Wetherington and Lucas (1980) was used to assess how well Herrnstein’s (1970) equation for the rates of responding during concurrent schedules described performance. The equation fitted some results very well, accounting for 80% or more of the variance in the data in studies that used moderate-duration changeover delays and provided the same positive reinforcers, operanda, and simple schedules in the two components. The equation fitted the data poorly in other studies. The k parameter changed with several variables; it was not as constant as Herrnstein (1974) suggested. R₀ did not fit Herrnstein’s interpretation as reinforcement from unprogrammed sources. Forty percent of all values of R₀ were negative, and another 23% were unreasonably large (greater than 50 reinforcers/h). The data suggest that Herrnstein’s equation is not a general theory of concurrent-schedule responding, and that Herrnstein’s interpretation of k and R₀ should be modified.     

The Problematic Nature of the Practicum: A Key Determinant of Pre-service Teachers’ Emerging Inquiry-Based Science Practices

This article disseminates findings from a multi-year study regarding secondary preservice science teachers’ perceptions toward inquiry-based science teaching, and the extent these perceptions are augmented by their practicum. While findings indicated that preservice teachers did improve their understanding and capability of using scientific inquiry due to their methods course, the role of practicum in supporting their newly developed perceptions was problematic. Issues ranging from associate teacher subjugation, availability of resources, time constraints, and the need to address curriculum standards were the most commonly cited reasons for preservice teachers’ difficulty in creating an inquiry-based environment during their practicum. Implications are presented highlighting the importance of practicum experiences as a key determinant of pre-service science teachers’ emerging inquiry-based science views and practices.     

Workplace as Community: Perspectives on Science Teachers’ Professional Learning

This study explores teacher professional learning within the workplace context of a science department community. Workplace learning is considered in terms of the construction and flow of information about science, pedagogy and the relationships of science to the wider community. Implications for establishing sound conditions for teacher workplace learning are also considered, particularly the importance of trust.     

Problematizing the Practicum to Integrate Practical Knowledge

This article examines the influence of a practicum teaching experience on two pre-service science teachers. The research is focused on examining a practicum in a secondary science department that actively promotes the teaching and learning of science as inquiry. We investigated the process through which the pre-service science teachers integrated their practical knowledge, and examined this in the context of the quantified reformed instruction they enacted. Using a mixed methods design, we have quantified these pre-service science teachers’ practice using the Reformed Teaching Observation Protocol (Piburn et al. 2000), in concert with a narrative methodology drawn from in-depth interviews. Our analysis of the data indicates two important conclusions. The first is the importance of a consistently reformed image of science education being presented and practiced by both science teacher educators and cooperating teachers. The second is the recognition that a consistently reformed image may not be sufficient, of itself, to challenge pre-service teachers’ views of science education. Pre-service teachers appear to be heavily influenced by their biographies and own science education. Consequently, it appears the extent to which a pre-service teacher identifies problems of teaching and learning, and then works toward possible resolution, influences their progress in shaping reformed views of science education.

Contesting continuing professional development: reflections from England

This paper argues the competing ways in which continuing professional development (CPD) is currently practised in schooling settings in England is a product of the complex social conditions within which teachers work and learn, and teachers’ efforts to make sense of these conditions. Specifically, the paper draws upon research into the teacher learning practices, and conditions of practice, of a group of 18 teachers from one inner-city comprehensive secondary school in the British Midlands. To make sense of competing approaches to CPD within the school, the paper analyses these teachers’ experiences in light of Pierre Bourdieu’s concept of social practices as contested. The research reveals competing approaches to teacher CPD in relation to the management of teachers’ CPD, the focus upon improving test scores and the modes of learning in which teachers participate. The paper shows how conflicting pressures and demands in the context within which teachers work, and teachers’ responses to these demands, contribute to contested practices in and across these domains, both arising from and resulting in what is described as a ‘hybridised’ habitus. The research gestures towards the need to cultivate conditions conducive to more educationally oriented, critical, situated and collaborative CPD.     

Embedded Library Services: From Cooperation to Collaboration to Enhance Student Learning in Asynchronous Online Course

The online environment presents a unique challenge to higher education. Shifting from the face- to-face format to online not only involves rethinking course design, but requires careful consideration of when and how to teach students, how to find and evaluate information needed to successfully complete coursework. One solution is faculty teaming with subject librarians to design and build in teachable moments. This case study discusses one such successful partnership from designing the course to choosing and embedding library resources and finally to the learning outcome of the online course.
