Dialectical Features of Students’ Argumentation: A Critical Review of Argumentation Studies in Science Education

This paper explores the challenges of using the Toulmin model to analyze students’ dialogical argumentation. The paper presents a theoretical exposition of what is involved in an empirical study of real dialogic argumentation. Dialogic argumentation embodies dialectical features — i.e. the features that are operative when students collaboratively manage disagreement by providing arguments and engaging critically with the arguments provided by others. The paper argues that while dialectical features cannot readily be understood from a Toulminian perspective, it appears that an investigation of them is a prerequisite for conducting Toulminian analysis. This claim is substantiated by a detailed review of five of the ten most significant papers on students’ argumentation in science education. This leads to the surprising notion that empirical studies in the argumentation strand — even those studies that have employed non-dialectical frameworks such as the Toulmin model — have implicitly struggled to come to terms with the dialectical features of students’ discourse. The paper finally explores how some scholars have worked to attend directly to these dialectical features; and it presents five key issues that need to be addressed in a continued scholarly discussion.     

Movement pattern and physiological response in recreational small-sided football – effect of number of players with a fixed pitch size

Recreational soccer is an effective health-promoting activity, but it is unclear how different game formats influence internal and external load. Thus, to be able to advise how to maximise the outcome of recreational football, we examined movement pattern and physiological response in 11 untrained men (32.6 ± 6.7 yrs, 23.3 ± 4.9 fat%, 43.4 ± 5.3 ml·min^?1·kg^?1) during three football sessions comprising 4 × 12 min of 3v3, 5v5 or 7v7 with a constant pitch size of 20 × 40 m. Movement pattern, heart rate (HR), blood lactate and RPE were measured during and after the 12-min periods. Greater (P < 0.05) total distance and high-speed distance was covered during 3v3 than 5v5 (14 and 30%) and 7v7 (15 and 75%). Mean HR was higher in 3v3 (85.7 ± 5.7%HRmax) and 5v5 (84.2 ± 5.1%HRmax) than in 7v7 (80.7 ± 4.6%HRmax, P < 0.05) and percentage time >90%HR was higher in 3v3 (43 ± 18%, P < 0.05) than in 5v5 (28 ± 21%) and 7v7 (18 ± 14%). Blood lactate was higher in 3v3 (7.4 ± 2.7 mmol·l^?1) than in 7v7 (4.5 ± 2.2 mmol·l^?1, P < 0.001) but not in 5v5 (6.1 ± 2.1 mmol·l^?1, P = 0.061). RPE was higher in 3v3 (6.7 ± 2.3, P < 0.01) than in 5v5 (5.2 ± 2.2) and 7v7 (4.3 ± 2.3). In conclusion, higher external and internal load was found with fewer players, when the pitch size is fixed.     

Developing the NAEP Content-Area Frameworks and Innovative Assessment Methods in the 1992 Assessments of Mathematics, Reading, and Writing

This article provides an overview of the consensus processes for the development of the frameworks underlying the NAEP assessments, with emphasis on those for the 1990 and 1992 assessments of mathematics, the 1992 assessment of reading, and the 1994 assessment of science. In addition, innovative assessment techniques included in the 1992 assessments of mathematics, reading, and writing are described, including use of mathematics tools, oral interviews, and portfolio assessment.     

Australia’s supervising teachers: motivators and challenges to inform professional learning

This paper offers an overview of what motivates and challenges Australian supervising teachers to work with preservice teachers in their classrooms. In the contemporary Australian context of new National Professional Standards for Teachers, a new national curriculum and new standards for Initial Teacher Education programs, what motivates and challenges supervising teachers becomes a focus for professional learning through analysis presented in this paper. Data are reported from a national data set that includes 314 responding supervising teachers who took the Mentoring Perspectives Inventory from 2012–2014. The MPI data are aggregated in this paper to suggest that the wider system of teacher education could benefit from attention at various levels of interest to develop the underlying knowledge base of supervising teachers and our understanding of how they are challenged and motivated in their work with preservice teachers.     

Student-environment interaction in the development of physical symptoms

This study identifies personal characteristics which distinguish university students who conform to living group norms in complaints of physical symptoms from those who do not. Discriminant function analyses indicated significant differences between these two groups of students, and between males and females. For example, low-symptom females living in high-symptom living groups who did not themselves increase in symptoms (environmental resisters) were higher in dominance and religious concern and lower in social participation than those who increased in symptoms. For males, important discriminators between conformers and resisters were academic achievement and alcohol consumption. Further specification of psychological variables which relate to the degree of conformity or resistance to environmental influence is central to understanding the impact of educational settings such as student living groups and classrooms.     

Students from divorced and blended families

Nielsen summarizes the research on the impact of parents' divorce and remarriage on elementary- and secondary-school students. By pointing out the shortcomings and discrepancies in the existing research, the author dispels several stereotypes often held by school personnel about students whose parents are divorced or remarried. Specifically, this article addresses the following questions: What factors affect grades and behavior after a divorce? How are children's attitudes toward divorce and family members assessed? In what ways can schools facilitate students' adjustment and academic performance after their parents divorce or remarry?     

Study procrastination, achievement, and academic motivation in web-based and blended distance learning

Growth in distance education is increasing the need to examine students' learning strategies in distance and blended learning environments. Students' cramming or spaced-review behaviors were measured and compared across delivery formats as well as examined related to course achievement and attitudes across a term. Although theory would predict that spaced study rather than last minute cramming would yield higher achievement, researchers report mixed findings in both areas. One hundred fifty-seven students in distance and blended course formats were blocked into 5 groups based on their cramming/spaced-review patterns a week prior to each of 3 posttests. Significant differences were observed in cramming/spaced-review behaviors between delivery formats and for achievement and attitudes.     

Teachers’ reflections of professional change during a literacy-reform initiative

Policymakers recently have targeted teacher quality, and school systems have increased their attention to instructional reform through professional development. The purpose of this study was to examine teachers’ views about the change process and professional development that supports change. Semi-structured focus-group data were gathered from 41 primary-grades teachers (students ages 5–9) across five schools in a high-poverty urban district that participated in a 2-year literacy-reform initiative. Results indicated that teachers viewed the change process from two stances: as learners and as change agents. Three conditions supported their professional growth: professional development embedded in school and classroom contexts, professional development focused on limited and clearly defined learning goals, and on-demand access to time and resources. Changes that occurred did so in three phases: movement from curriculum-centered to student-centered practices, increased collaboration, and requests for policy changes via teacher autonomy and advocacy for students.
