Proof and application

This paper outlines an epistemological conception which attempts to relate the formal aspects of mathematical proof to its pragmatic dimensions. In addition to the key concept of application, the paper makes use of several concepts from the domain of analytical philosophy, to present a view of proof that might best be categorized as a dialectical one. A number of implications for teaching are discussed.     

Articulating the validity evidence for a science alternate assessment

Students with the most significant cognitive disabilities (SCD) are the 1% of the total student population who have a disability or multiple disabilities that significantly impact intellectual functioning and adaptive behaviors and who require individualized instruction and substantial supports. Historically, these students have received little instruction in science and the science assessments they have participated in have not included age‐appropriate science content. Guided by a theory of action for a new assessment system, an eight‐state consortium developed multidimensional alternate content standards and alternate assessments in science for students in three grade bands (3–5, 6–8, 9–12) that are linked to the Next Generation Science Standards (NGSS Lead States, 2013 ) and A Framework for K‐12 Science Education (Framework; National Research Council, 2012 ). The great variability within the population of students with SCD necessitates variability in the assessment content, which creates inherent challenges in establishing technical quality. To address this issue, a primary feature of this assessment system is the use of hypothetical cognitive models to provide a structure for variability in assessed content. System features and subsequent validity studies were guided by a theory of action that explains how the proposed claims about score interpretation and use depend on specific assumptions about the assessment, as well as precursors to the assessment. This paper describes evidence for the main claim that test scores represent what students know and can do. We present validity evidence for the assumptions about the assessment and its precursors, related to this main claim. The assessment was administered to over 21,000 students in eight states in 2015–2016. We present selected evidence from system components, procedural evidence, and validity studies. We evaluate the validity argument and demonstrate how it supports the claim about score interpretation and use.     

Sign language for hard of hearing children — A hindrance or a benefit for their development?

In 1981, sign language was declared an official language in communication with and education of deaf children in Sweden. Today, the debate is focused on language communication for hard of hearing children. In order to describe patterns of interaction between hard of hearing and deaf children as well as between hard of hearing children, a longitudinal, qualitative study was conducted. Twenty-seven children, 2 and 7 years of age, participated. Fifteen were deaf, twelve hard of hearing. Video-recorded observations were made at three daycare centres during a two year period. Observations were made in natural interactional settings. The results showed that the use of a language code that was easy for the children to produce as well as to perceive enabled them not only to take part in dialogues and to share experiences with others, but also had positive consequences for their play as well as their social and emotional development. A child-centered and supportive communicative style of the adults, in combination with a positive attitude towards fantasy and role plays seemed to promote the children’s overall development, as contrasted to an adult-centered and directive communicative style where language per se was in focus.     

Changing Notions of Lifelong Education and Lifelong Learning

Drawing on material from IRE as well as other sources, this article describes how the notion of lifelong education came into prominence in the educational world in the late 1960s, how it related to the concepts of formal, non-formal and informal education, and how it contrasted with the idea of recurrent eduction, as promoted by the OECD. The author goes on to discuss the emergence of the broader and more holistic concept of lifelong learning and the various ways in which it is understood. The article shows how IRE and its host institute have played an important part in the debate on these issues.     

The changing nature of expertise: insights from the case of TAVI

ABSTRACT

In this paper, we interrogate the current views on medical expertise, and expertise more in general, by building upon the study of an innovative medical procedure called transcatheter aortic valve implantation (TAVI). We find that phenomena like TAVI require that we modify our traditional views of expertise to acknowledge its social, material and distributed nature. We also find that in the case of TAVI expertise feeds upon the broad circuits of knowledge created by the combination of professional relationships, social ties and, increasingly, economic interests. Becoming and remaining an expert implies not only being socialised in a local regime of activity but increasingly also participating in, learning to navigate, and exploiting alternative and potentially competing circuits of knowledge, which may be controlled by private companies. The case of TAVI helps us to appreciate expertise as a translocal and connected phenomenon and foreground some of the implications of the emergence of proprietary circuits of knowledge.     

Different Sources, Different Answers: Aspects on Women's Work in Sundsvall, Sweden, 1860–1893

It is often hard to unravel the actual work of women in history. Generally few sources are able to give vital information on their occupational structure. What we know, though, is that a vast majority of women were engaged in domestic work. Servants frequently appear in quantitative data, such as parish registers, poll-taxes, or censuses. Nevertheless, these sources fail to cover what women really were doing in order to pay for their daily bread. But in what ways the occupation reported in the quantitative records disagreed from women's actual work is difficult to judge. Additionally, in many cases these records leave no occupational information on women at all. With the computerized parish registers of the Demographic Data Base at Umeå University, Sweden, it is possible to link alternative information on individual women's work to the quantitative data and build on the picture of women's occupations. Consequently, whereas the parish registers enable us to deal with demographic issues concerning the marital, geographical, and social path of women in the past, the alternative sources formed by local newspapers, patient records, and business statistics offer further information on their life and working conditions. This paper reveals that alternative sources are better than the quantitative data at revealing the often multi-occupational and part-time work of urban women. Newspaper advertisements, announcements, and police reports, for instance, reveal the voices of the otherwise silent women workers and tell us about their urban context. The town and time in focus is Sundsvall in 1860–1893, a Swedish sawmill town situated about 400 kilometers north of Stockholm.     

Curriculum research for students with intellectual disabilities: a content-analytic review

Curriculum content, the issue of what to teach is fundamental. For students with intellectual disabilities (ID), the choice of educational content is crucial in a life span perspective. Curriculum research for this learner group is sparse. Drawing on a curriculum approach, the purpose of this content analytic reviw study is to analyse trends in curricular research, and discuss implications for further curricular research and policy. Curricular research articles from 1994 to 2016 were identified from databases, using systematic search procedures and specific criteria for inclusion and categorisation of the literature. Based on prior review studies, functional life skills and cognitive academic content formed the analytical fulcrum. The results showed that cognitive academic articles had the highest coverage in the literature and showed a steep increase in publication frequency compared to functional life skill articles. If curricular research on functional life skills stagnates, curriculum policy and practice may fail to provide students with ID the skills necessary for social and practical adaption in their communities. A discursive connection to normative curricular frameworks is essential to analyse and guide curricular choices. This article provides analytical insight and directions for future research in the field of curriculum research for students with ID.     

Self-rated mental health, school adjustment, and substance use in hard-of-hearing adolescents

This survey, "Life and Health-Young People 2005," included all 15/16-year-old adolescents in mainstream schools in the county of Orebro, Sweden. Just students with a slight/mild or moderate hearing loss were included. There were 56 (1.9%) "hard-of-hearing (HH) students with multiple disabilities," 93 (3.1%) students who were "just HH," 282 (9.7%) students with some "other disability than HH," and 2,488 (85.2%) students with "no disability." "HH with multiple disabilities" reported considerably higher scores for mental symptoms, substance use, and school problems than the "no disability" group. Those with "just HH" and those with "other disability than HH" had more mental symptoms and school problems than the "no disability" group but no significant differences in substance use. In conclusion, the combination of a hearing loss and some other disability strongly increases the risk for mental symptoms, school problems, and substance use. This group, thus, is an important target for preventive measures.     

Still Academic and National – Internationalisation in Norwegian Research and Higher Education

The paper discusses strategies for internationalisation in Norwegian research and higher educational institutions in terms of understanding them in relation to the organisations’ relation to environments and/or in relation to the organisations basic values and identities. The empirical material consists of six case studies (3 universities, 2 university colleges and 1 research institute). Points of departure are observed through increasing competition, normative transformations in terms of increasing economic justifications of internationalisation and impetus to coherent strategic actions. To what extent does the Norwegian landscape of responses to internationalisation fit such interpretations? Based on this case study we may safely conclude that increased competition as a major driver of internationalisation policies and practices in these organisations is still to come. An economic justification of policies and practices is not the major reason to internationalise, given the perceptions of these organisations. They are currently deeply embedded in academic rationales for internationalisation.     

Sourcing in Text Comprehension: a Review of Interventions Targeting Sourcing Skills

The process of using information about documents such as the author, genre, and date of publication while evaluating and interpreting those documents’ content was labeled “sourcing” in a seminal paper by Wineburg (Journal of Educational Psychology, 83, 73, 1991). Studies in various domains have adapted the term sourcing while referring to central reading skills in modern information societies. In this review, we discuss the concept of sourcing grounded in research from social psychology, information sciences, and text comprehension. Based on that, we reviewed 18 intervention studies in educational settings, in order to identify how sourcing was operationalized in the studies, the nature of the interventions, and how successful they were. The review shows that interventions for younger students emphasized source credibility, whereas interventions among older students also emphasized the role of sourcing in interpretation. None of the studies measured how students search for source features or specifically which features they attend to. Regarding the nature of the studies, the use of multiple partly conflicting documents was common, with that condition positively related to outcome measures. Another characteristic was the use of inquiry tasks. A majority of the studies do not apply findings from persuasion theory and information science indicating that credibility assessment requires effort and motivation. Future interventions should more strongly emphasize the relationship between sourcing and motivation.
