Generalizability and Validity of the Use of a Case Analysis Assessment to Make Visible the Quality of Teacher Candidates

The use of case analysis as an accountability measure for demonstrating teacher candidates abilities to meet targeted course, institutional, and state teaching standards for student motivation and classroom management was evaluated. The findings supported the generalizability of case analysis ratings made using a standards-based scoring rubric, and the ratings were shown to differentiate levels of performance in accordance with those standards. Support for the content representativeness of the performance assessment was also obtained using criteria suggested by Crocker (1997), including the realism, frequency, necessity, and importance of the targeted teaching behaviors to actual teaching practice. The findings also provided initial support for the predictive validity of the case analysis assessment for appraising candidates overall abilities to manage a public school classroom.     

Classroom Use of Multimedia-Supported Predict–Observe–Explain Tasks in a Social Constructivist Learning Environment

This paper focuses on the use of multimedia-based predict–observe–explain (POE) tasks to facilitate small group learning conversations. Although the tasks were given to pairs of students as a diagnostic tool to elicit their pre-instructional physics conceptions, they also provided a peer learning opportunity for students. The study adopted a social constructivist perspective to analyse and interpret the students conversations, focussing on students articulation and justification of their own science conceptions, clarification of and critical reflection on their partners views, and negotiation of new, shared meanings. Two senior science classes participated in this interpretive study. Data sources were mainly qualitative and included audio and video recordings of students small group discussions at the computer, interviews with selected students and their teachers, classroom observations, and student surveys. Findings indicate that the computer-based POE tasks supported students peer learning conversations, particularly during the prediction, reasoning and observation stages of the POE strategy. The increased level of student control of the POE tasks, combined with the multimedia nature of the program, initiated quality peer discussions. The findings have implications for authentic, technology-mediated learning in science.     

What the Pendulum Can Tell Educators about Children’s Scientific Reasoning

Inhelder and Piaget (1958) studied schoolchildrens understanding of a simplependulum as a means of investigating the development of the control of variablesscheme and the ceteris paribus principle central to scientific experimentation.The time-consuming nature of the individual interview technique used by Inhelderhas led to the development of a whole range of group test techniques aimed attesting the empirical validity and increasing the practical utility of Piagets work.The Rasch measurement techniques utilized in this study reveal that the Piagetian Reasoning Task III — Pendulum and the méthode clinique interview revealthe same underlying ability. Of particular interest to classroom teachers is theevidence that some individuals produced rather disparate performances across thetwo testing situations. The implications of the commonalities and individualdifferences in performance for interpreting childrens scientific understanding arediscussed.     

Sensing the Impact of Elementary School Science Reform: A Study of Stakeholder Perceptions of Implementation,Constructivist Strategies,and School–Home Collaboration

This case study of a midwestern school districts reform effort explored the treatment fidelity of the Science: Parents, Activities, and Literature (Science PALs) project. Data were collected from the perspectives of three stakeholders: students, school district, and parents. Students and school district supervisors perceptions indicated that teachers were implementing predicted curricular and instructional features promoted by the Science PALs project. Students perceptions of their current teachers classroom performance did not parallel the supervisors perceptions of the teachers implementation. Parents perceptions and comments indicated a high level of satisfaction with the implemented features. Collectively, the three perspectives suggest that the Science PALs project was successful in changing the classroom practices of K–6 teachers involved in the professional development. The results of this study appear to support the findings of other recent studies that indicate the need for extended professional development and support to fully implement changes in elementary school science instruction.     

Policy communities,issue networks and the formulation of Australian higher education policy

Governments in most western countries consult extensively with clientele groups in the process of formulating higher education policy. The nature of these consultative mechanisms, in turn, influences the manner in which decisions are made, and the substance of policy outcomes. This article explores the changing style of government-interest group interaction in Australia over the decade 1985–94 and how these changes have effected the way policy is determined. It is argued that Australia has gone through three phases over that time. Until 1987 policy was formulated by a stable policy community. From 1988–90, when a number of major reforms were introduced, this framework was replaced by a brief period of state direction. During the early 1990s a new environment characterised by unstable issue networks emerged.     

The Nature of Science and Science Education: A Bibliography

Research on the nature of science and science education enjoys a longhistory, with its origins in Ernst Mach's work in the late nineteenthcentury and John Dewey's at the beginning of the twentieth century.As early as 1909 the Central Association for Science and MathematicsTeachers published an article – A Consideration of the Principles thatShould Determine the Courses in Biology in Secondary Schools – inSchool Science and Mathematics that reflected foundational concernsabout science and how school curricula should be informed by them. Sincethen a large body of literature has developed related to the teaching andlearning about nature of science – see, for example, the Lederman (1992)and Meichtry (1993) reviews cited below. As well there has been intensephilosophical, historical and philosophical debate about the nature of scienceitself, culminating in the much-publicised Science Wars of recent time. Thereferences listed here primarily focus on the empirical research related to thenature of science as an educational goal; along with a few influential philosophicalworks by such authors as Kuhn, Popper, Laudan, Lakatos, and others. Whilenot exhaustive, the list should prove useful to educators, and scholars in otherfields, interested in the nature of science and how its understanding can berealised as a goal of science instruction. The authors welcome correspondenceregarding omissions from the list, and on-going additions that can be made to it.     

Putting Thought in Accordance with Things: The Demise of Animal-Based Analogies for Plant Functions

Scientists' attempts to understand plant functions by ascribing animal functions to plants – the analogist tradition, derived from Aristotle – began to be superseded in Europe by an experimentalist tradition in the seventeenth century. In classrooms today, science students learning about plant functions (exemplified here by the topic of transpiration) face a parallel dilemma: the pitching of their own habitual mental processes of analogy building (enhanced by the suggestive morphology of plants)and the persuasiveness of everyday language (for example, about plants and water)against the new experimental evidence presented by the teacher. In the case oftranspiration, six practical suggestions whereby teachers can support students in thisstruggle to put their thoughts (especially everyday mental models) in accordance withthings (classroom experimental evidence) are advanced. The wider implications forhow we teach about Living Things, and how we view the status of analogies in sciencegenerally, are discussed.     

Teaching–research relations,cross-disciplinary collegiality and student learning

University students experience of cross-disciplinary collegiality and interaction with research-active teachers are explored using the results from two separate, but related, studies. In the first study, variation in students understanding of collegiality and how it is experienced is investigated. The second (quantitative) study explores the relations between students perceptions of collegiality in their learning environment and their learning outcomes and satisfaction. Within the collegiate system of the University of Oxford, students describe collegiality as encompassing a sense of allegiance and as a set of interactions with important others. Interactions were common between students in one disciplinary area and those in other disciplines. They are also found between students in one subject and other students in the same discipline, in the same and a different year of study and, in terms of learning, most effectively between students and research-active teaching staff. Where engagements of these sorts are described as beneficial to learning, students self-report that they adopt deeper approaches to learning, with the strongest correlations being between approach to learning and feelings of benefit derived from being in contact with active researchers. This result, from a student perspective, is a significant contribution to the debate on teaching–research relations in higher education within and beyond Oxford University as it bypasses teaching and focuses on the more important relations between university research and student learning.     

Student evaluations of teaching effectiveness: a Nigerian investigation

An investigation is reported which tests the applicability of two American instruments designed to assess tertiary students' evaluations of teaching effectiveness with 158 Nigerian undergraduates. The scales were found to have generally high internal consistency reliability coefficients, most of the items were seen to be appropriate, and every item was considered of importance by at least some of the students. In addition, all but the Workload/Difficulty items clearly differentiated between good and poor lecturers. Factor analysis found a strong main factor of teaching effectiveness plus a minor factor referring to course workload and difficulty. Further analysis generally supported the convergent and discriminant validity of those scales hypothesized to measure similar or dissimilar components of effective teaching. However, this analysis supported the factor analytic results as more overlap between aspects of teaching skill and enthusiasm was found than has been evident in Western studies. Thus there must be doubt about the cross-cultural validity of a multidimensional model of teaching effectiveness.     

Idealisation and Galileo’s Pendulum Discoveries: Historical, Philosophical and Pedagogical Considerations

Galileos discovery of the properties of pendulum motion depended on his adoption of the novel methodology of idealisation. Galileos laws of pendulum motion could not be accepted until the empiricist methodological constraints placed on science by Aristotle, and by common sense, were overturned. As long as scientific claims were judged by how the world was immediately seen to behave, and as long as mathematics and physics were kept separate, then Galileos pendulum claims could not be substantiated; the evidence was against them. Proof of the laws required not just a new science, but a new way of doing science, a new way of handling evidence, a new methodology of science. This was Galileos method of idealisatioin. It was the foundation of the Galilean–Newtonian Paradigm which characterised the Scientific Revolution of the 17th century, and the subsequent centuries of modern science. As the pendulum was central to Galileos and Newtons physics, appreciating the role of idealisation in their work is an instructive way to learn about the nature of science.     

Cognitive Empathy and the Transition to Independent Graduate Study in Mathematics

Thirteen Ph.D. students took part in interviews focussed on the nature of their own learning of mathematics. In analysing these interviews an unexpected category emerged concerning the students awareness of others as having particular types of learning goal. In this paper we explore the three levels which we discerned within this category and link them to the notion of cognitive empathy. We suggest that differences in ones own cognitive style are linked to differences in the ability to empathise with those who have alternative learning goals. We also consider how these two features – cognitive style and cognitive empathy – may come to be linked.     

Privatisation,Decentralisation and Education in the United Kingdom: The Role of the State

Since the early 1950s, the axis centralisation–decentralisation, especially as thematised in the work of Isaac Kandel, has represented a major focus of comparative studies in education. Kandel argued that issues relating to the internal conduct of the classroom (interna) should, so far as possible, be decentralised, while issues relating to administration, school structure and organisation of the educational system (externa) might safely be centralised. After 1988, successive governments in the United Kingdom have undertaken reforms which have placed more central control on the curriculum and even methods of teaching (interna), while school finance and administration (externa) have been devolved to the school level. The present essay argues that a simplistic approach to centralisation and decentralisation is not likely to be fruitful. Instead, we should acknowledge the role of the State in creating a permissive framework for educational systems. Local action can then be seen as part of a policy accommodating or resisting the implications of that framework.     

Analyzing children's errors on written mathematical tasks

Methods developed by Newman and Casey for analyzing errors made by children attempting verbal arithmetic problems are described, with particular emphasis being given to Newman's hierarchy of error causes. Data obtained by Newman, Casey, and Clements are presented. These show that a large proportion of errors made by children in grades 5–7 in Victoria on verbal arithmetic problems are in the Newman categories Comprehension, Transformation, Process Skills, and Carelessness.     

The development of students’ ways of thinking and practising in three final-year biology courses

Findings are presented from an ongoing study of three final-year, honours-level course units in the biosciences with a combined intake of 85 students. The data on which the analysis draws comprise semi-structured interviews with students together with findings from an Experiences of Teaching and Learning Questionnaire. The investigation forms part of a wider project concerned with the enhancement of teaching–learning environments in undergraduate courses in contrasting subject areas. The findings presented in the paper focus on two interrelated aspects of the students experiences within the teaching–learning environments represented by the three course settings. First, salient aspects of high-quality undergraduate-level learning are identified in the form of the students evolving grasp of characteristic ways of thinking and practising in the subject. These ways of thinking and practising in the biosciences were evident in the students engagement with the research literature and with experimental data, and in their efforts to master the requirements and conventions of the subject for written and oral discourse. The second part of the analyses focuses on the teaching–learning environments represented by the three course settings. It was found that, despite taking markedly different forms in the three settings, the teaching–learning and assessment strategies pursued appeared to be broadly congruent with the promotion of ways of thinking and practising in the subject. The quality of feedback to students also seemed pivotal, but needed to be understood in terms of the interplay of various factors, including opportunities for intrinsic as well as extrinsic feedback. Finally, the later years of undergraduate studies had called for a significant process of adjustment on the students part to a step-change in study demands.     

Enhancement of Quality in Chemical Inquiry by Pre-University Students

Our pre-university chemistry students face problems achieving sufficient quality in chemical inquiry. To try to enhance the quality of student performance in chemical inquiry, Dutch pre-university chemistry students (age 17) carried out an authentic research project on Diffusion of ions in distilled water. The learning materials for this student inquiry project, the teaching scenario and the website were designed in cooperation with five chemistry teachers. Three teachers from this network and two other teachers also implemented the project with 80 students to find out whether the emphasis on relevant concepts of evidence (CoE) improves the quality of student inquiry outcomes. This part – with its emphasis on the CoE – in the student inquiry task is based on four key features: the students feel motivated to explore, focus their attention on, give meaning to and reflect upon CoE. In teams students conducted a guide experiment, analysed a scientific article, did an inquiry and wrote a report, discussed CoE with peers on the Internet and rewrote their reports. All lessons were observed, field notes were made and analysed on whether the intended student activities had been realised. The Internet discussion was recorded in a database and analysed. The first and final reports of all teams were coded and analysed. Also the students appreciation of the activities was assessed. The teaching and learning activities were realized to a very large extent as planned in the design. The emphasis on CoE resulted in 65% of the students achieving a sufficient level of quality in their final reports.     

A Window for a Purpose: Developing a Framework for Describing Effective Science Teaching and Learning

This paper describes the development of a framework – the SIS Components – for describing effective teaching and learning in science, to support a system wide change initiative. The methodology used and the analysis that led to their refinement, is traced to expose the different issues involved in constructing the notion of effective practice. These issues have to do with purpose, politics and audience. They determine features of the framework such as specificity, elements focused on, and the support structures that are put in place to establish the particular discourse being promoted. The paper describes the different research methods used to establish, to promote and to validate the components, and outlines the different senses in which this and any framework can be seen as contingent on the setting for which it is intended.

Third Graders' Interpretations of Equality and the Equal Symbol

This paper analyzes the interpretations of equality and the equal symbol of the third-grade children who participated in a year long whole-class socio constructivist teaching experiment. These children initially interpreted the equal symbol as a command to perform an arithmetical operation; it was less natural to them to interpret it as a relational symbol to compare two quantities. By the end of the school year, children were able to conceptualize the quantitative sameness of two numerical expressions and describe it by using the phrase is the same as, the words equal or equals, or the symbols = or =s. These children expanded their conceptualizations of equality due to their active role in class discussions, the arithmetical tasks that took into account children's difficulties, and the teacher's intellectual sensitivity to strike a delicate balance between the force of teaching and the freedom of learning (Freudenthal, 1991, p. 55).
