Using Toulmin’s Argument Pattern in the evaluation of argumentation in school science

Toulmin's definition of argument has been used by researchers as a theoretical perspective on argument and as a methodological tool for analysing episodes of oral argumentation. An adaptation of Toulmin's framework used by researchers has informed a professional development programme for teachers. Research on the impact of the programme on pedagogic practice shows that Toulmin-based materials are advantageous in helping teachers to conceptualise argument and model it for students. However focus on the process of argumentation limits any consideration of the content and quality of evidence. Toulmin's framework can also be used to evaluate student outcomes when using argumentation software

Learning to teach ideas and evidence in science: a study of school mentors and trainee teachers

This article reports on a small-scale evaluation of how beginning teachers undertaking a PGCE in secondary science worked collaboratively with their school based mentors to enhance practice in the use of ideas and evidence in science. Mentors and beginning teachers were introduced to the resources and teaching strategies previously developed at King’s College London as part of the Nuffield funded IDEAS curriculum development project (Osborne, Erduran & Simon, 2004a). The judicious selection of resources and strategies from the IDEAS pack formed the basis of mentors’ workshops, where mentors were encouraged to put into practice IDEAS and other argumentation activities and strategies. Collaborative work with their mentors enabled the BTs to initiate their teaching of ideas and evidence. They experienced both positive aspects and limitations when attempting IDEAS activities in their science classrooms

Profile Analysis on the WISC-IV and WAIS-III in the low intellectual range: Is it valid and reliable?

This paper examines how far it is valid to generate a profile of an individual’s cognitive abilities using the WISC-IV or WAIS-III for individuals in the low ability range. Data are presented which demonstrate that the WISC-IV and WAIS-III assessments produce different cognitive profiles, when given to the same 16-year-olds who receive special education. It is suggested that at the low IQ level, subtest and index scores may lack sufficient stability for the WISC-IV or WAIS-III to produce reliable cognitive profiles

Does a simple educational exercise influence practice in acute tonsillitis in children?

Aim: To assess the concordance of treatment of children attending with tonsillitis in Paediatric Accident and Emergency with established guidelines, and subsequent review of the management of this condition after a simple educational exercise. Methods: An audit on children with tonsillitis was carried out amongst doctors working in the Paediatric Accident and Emergency Department during a three month period in 2009. Eleven doctors completed an anonymous questionnaire requesting details on presentation, symptoms, investigations and treatment of children presenting with acute tonsillitis. The results obtained from this questionnaire were compared to NICE guidelines and modified Centor (McIsaac) criteria, and fed back to the participating doctors together with copies of these guidelines via a simple, structured educational exercise. Three months later, a second identical questionnaire was again completed by the same cohort of doctors. Results: The first questionnaire showed that there was a tendency towards unnecessary prescription of antibiotics and investigations in children with acute tonsillitis, when compared to recommendations in the guidelines. Following educational feedback, the second questionnaire showed a reduction in antibiotic prescriptions by 9% (p=0.5) and investigations by 37% (p=0.1). Compliance with guidelines had improved significantly with regard to non-prescribing of antibiotics with a fever of 1cm and presence of underlying disease although these changes were not statistically significant. Conclusion: Although doctors were initially only partly compliant with established guidelines for children with acute tonsillitis, compliance improved significantly after a simple educational exercise.peer-reviewe

A comparison of the WISC-IV and WAIS-III in the low IQ range

A diagnosis of intellectual disability (ID), mental retardation (MR) or Learning Disabilities (LD) can have a major effect on people’s lives. On the positive side it can provide services, finance, help in schools, and can even prevent the recipient from being executed (Flynn 2006; Flynn 2007; Schalock et al 2007). On the negative side it is may be regarded as a stigmatizing label that an individual may seek to avoid (Baroff 1999). Currently a necessary though not sufficient part of the diagnosis of ID is having an IQ below a specified figure, usually 70, or two standard deviations (SDs) below the norm (American Association on Mental Retardation, 2002; American Psychiatric Association 2000; Department of Health 2001; British Psychological Society 2001). This specification of a specific IQ figure implies that an individual has a “true IQ” that can be measured. If different IQ tests systematically measure either higher or lower than other tests it would raise the question as to which IQ test was providing the best estimate of an individual’s true IQ. In the absence of a test that is clearly an accurate measure of true IQ, the best that could be done would be to decide which of the many IQ tests is likely to be the most accurate, and take that as the “gold standard” assessment against which other assessment should be compared. The Wechsler assessments, the WISC-IV and the WAIS-III should have a good claim to be regarded as the gold standard assessments. However, for these assessments to be accepted as gold standard assessments for the diagnosis of ID, it requires that they should produce equivalent IQ scores in the low ability range. We compared the WISC-IV and WAIS-III on a group of 16-year-olds in special education. Sixteen being the age group at which both assessments can be used. Both the WISC-IV and the WAIS-III were given to seventeen 16-year-olds (9 female and 8 male) attending local special schools in counterbalanced order. The results were as follows: WISC-IV WAIS-III Diff r Mean Full Scale IQ 53.00 64.82 11.82 .93 In spite of a very high correlation between the two scales there was a highly significant difference between the mean FS IQ on each scale of nearly 12 points (P<.001 on t-test); none of the participants in the study scored higher on the WISC-IV than they did on the WAIS-III. It is therefore clear that either one or both of these assessments is failing to produce an accurate measure of an individuals true IQ. As the degree to which either assessment is in error is not known, it is clearly possible that either the WISC-IV is systematically underestimating true IQ by up to 12 points, or the WAIS-III is systematically overestimating true IQ by 12 points or both assessments are making systematic errors of less than 12 points. Clearly this has implications for the use of a specified IQ figure as a diagnostic criterion for ID. Summary of abstract The WISC-IV and WAIS-III were given to seventeen 16-year-olds in special education in counterbalanced order. The mean FS IQ on the WISC-IV was 53.00 and on the WAIS-III it was 64.82 a difference of nearly 12 points. The correlation between the two assessments was .93. It is therefore clear that either one or both of these assessments is failing to produce an accurate measure of an individuals true IQ

Professional Learning Portfolios for Argumentation in School Science

This paper reports on the use of portfolios in a continuing professional development programme to advance teachers’ skills in their pedagogy of argumentation. The programme adopted a cyclical process of expert input- teacher practice- sharing practice, in order for professional learning to include reflective analysis of growing accomplishment. Accomplishment was initially defined according to previous research and development on the teaching of argumentation, but was redefined during the programme as teachers shared practice and discussed their achievements. Portfolios were used to help teachers apply their learning, collate evidence of their accomplishment and share reflective analysis of practice with other colleagues on the programme. The paper includes extracts of two teachers’ portfolios; these provide evidence of each teacher’s developing accomplishment in the teaching of argumentation. Portfolios are idiosyncratic and are constructed according to an individual teacher’s motivations, interpretations and situations. Teachers need structure and guidance in creating purposeful portfolios that enhance reflective practice

Enhancing the Quality of Argumentation in School Science

The research reported in this paper focussed on the design of learning environments that support the teaching and learning of argumentation in a scientific context. The research took place over two years between 1999 and 2001 in junior high schools in the greater London area. The research was conducted in two phases. In the first developmental phase, working with a group of 12 science teachers, the main emphasis was to develop sets of materials and strategies to support argumentation in the classroom and to assess teachers‘ development with teaching argumentation. Data were collected by videoing and audio recording the teachers attempts to implement these lessons at the beginning and end of the year. During this phase, analytical tools for evaluating the quality of argumentation were developed based on Toulmin‘s argument pattern. Analysis of the data shows that there was significant development in the majority of teachers use of argumentation across the year. Results indicate that the pattern of use of argumentation is teacher specific, as is the nature of the change. In the second phase of the project, teachers taught the experimental groups a minimum of nine lessons which involved socioscientific or scientific argumentation. In addition, these teachers taught similar lessons to a control group at the beginning and end of the year. Here the emphasis lay on assessing the progression in student capabilities with argumentation. Hence data were collected from several lessons of two groups of students engaging in argumentation. Using a framework for evaluating the nature of the discourse and its quality, the findings show that there was an improvement in the quality of students‘ argumentation. In addition, the research offers methodological developments for work in this field

Professional Development: An MSW Course Based on Group Work Principles and Opportunities

Professional development is a critical but frequently overlooked aspect of students’ education. This paper chronicles a group work-based MSW elective course that explores issues of professional identity and responsibility within a contemporary context, develops projects focused on individually-determined professional interests, and provides opportunities to participate in and present at professional conferences such as the International Association for Social Work with Groups (IASWG) Symposium. The syllabus, feedback from students, and recommendations for replication are shared
