Design‐based Research: Case of a teaching sequence on mechanics

Design‐based research, and particularly its theoretical status, is a subject of debate in the science education community. In the first part of this paper, a theoretical framework drawn up to develop design‐based research will be presented. This framework is mainly based on epistemological analysis of physics modelling, learning and teaching hypotheses. It includes grand theories, a specific theory that following Cobb, Confrey, diSessa, Lehrer, and Schauble is a “humble theory” in the sense that it does “real work”, and tools for design. In the second part, we will show how this specific theory and its tools led designers to develop teaching resources in the case of a teaching sequence on mechanics (Grade 10). We will explain how the components of the specific theory and tools guide the design at different levels; the conceptual structure of the teaching sequence, the chronology of the activities, the various choices of the type of activity and their wording. This presentation makes the bases of designing teaching resources explicit and therefore allows for scientific debate.     

The posts continue: becoming

This paper describes assumptions of representational logic and phenomenology that organize much of Enlightenment humanism and one of its knowledge projects, conventional humanist qualitative methodology. The author argues that the ontological critiques of “post” theorists, including Foucault, Derrida, Baudrillard, Lyotard, and Deleuze and Guattari, were set aside in favor of epistemological projects following World War II and that, in general, the “posts” had little effect on that methodology. Those critiques are now being put to work and extended in the new empiricism and new materialism to re-imagine being, always an ethical task. Whether humanist qualitative inquiry can survive the ontological turn is a question to consider.     

A multidimensional model of school dropout from an 8-year longitudinal study in a general high school population

This study tests an empirical multidimensional model of school dropout, using data collected in the first year of an 8-year longitudinal study, with first year high school students aged 12–13 years. Structural equation modeling analyses show that five personal, family, and school latent factors together contribute to school dropout identified at 19 years of age: poor parent–teenager relationships, youth depression and family difficulties, negative classroom climate, negative school interactions, and poor academic achievement. This model increases our understanding of the dropout process in the general population and has direct implications for the development of high school dropout prevention programs.     

Agricultural Extension Services and Market Regulation: Learning from a Comparison of Six EU Countries

Abstract

If farmers are to meet the new challenges facing agriculture (environment, rural development, etc.), appropriate knowledge has to be produced. But observations in six EU countries (France, Germany, Greece, the Netherlands, Spain and the UK) show that unexpected problems arise when technical support for agriculture is linked to market regulation, as recommended since the late 1980s. The source of these problems can be understood better by applying concepts from the service economy: i) The production of new knowledge requires strong interaction between service providers (technical support bodies) and beneficiaries (farmers). The weakening of non-market regulation procedures, which partly guaranteed these possibilities of interaction, makes the conception of an advisory service difficult. ii) As soon as consultancy becomes a paying service, some beneficiaries reduce technical interaction with their colleagues in order to benefit from a productive advantage, and the ‘multipliable’ nature of new knowledge is reduced. iii) An increasing number of farmers are excluded from the benefits of technical support even though they help to provide services that society expects from agriculture (management of the land, maintenance of activities in low-density areas). iv) The responsibility for combining contradictory requirements (competitiveness, environment, rural development) is most often put on the shoulders of individual farmers who are unequipped to deal with such complex issues. Observed trends attest to the fact that effects often run counter to the stated agricultural and rural development objectives of policies.     

Constructions of mathematicians in popular culture and learners’ narratives: a study of mathematical and non‐mathematical subjectivities

In this paper, based on a project funded by the UK Economic and Social Research Council considering how people position themselves in relation to popular representations of mathematics and mathematicians, we explore constructions of mathematicians in popular culture and the ways learners make meanings from these. Drawing on an analysis of popular cultural texts, we argue that popular discourses overwhelmingly construct mathematicians as white, heterosexual, middle‐class men, yet also construct them as ‘other’ through systems of binary oppositions between those doing and those not doing mathematics. Turning to the analysis of a corpus of 27 focus groups with school and university students in England and Wales, we explore how such images are deployed by learners. We argue that while learners’ views of mathematicians parallel in key ways popular discourses, they are not passively absorbing these as they are simultaneously aware of the clichéd nature of popular cultural images.     

Parental education and the socialization of the child: Internality, valorization and self-positioning

Contemporary western society is characterised by an individualistic model of the person. Conceptions of socialization insist more on self expression and development than on the individual’s submission to social requirements. Values concerned with individual responsibility and self-realization guide educative actions. The article analyses the influence of parental education on internality and self-esteem in the child with particular attention to how parents lead the child to become responsible (commitment). Two hundred parents (from contrasting social backgrounds) answered a questionnaire on internality and a question on self-esteem. According to their social background, the parents adopt educative practices which induce more or less responsibility in the child. Leading the child to accept responsibility in daily life encourages the learning of internality, but family education has little influence on self-esteem. How subjects “positioned” themselves, i.e., how they placed themselves a variety of measures was examined. Some preferred to position themselves in the centre of the scales while others placed themselves on the extremes. There was a correlation between the positioning of the parents and that of the children.     

Poststructural feminism in education: An overview

Feminists in education increasingly use poststructuralism to trouble both discursive and material structures that limit the ways we think about our work. This overview of poststructural feminism presents several key philosophical concepts ? language; discourse; rationality; power, resistance, and freedom; knowledge and truth; and the subject ? as they are typically understood in humanism and then as they have been reinscribed in poststructuralism, paying special attention to how they have been used in education.     

CONSUMERISM AND THE AGING

The need for consumer health education for the aged has been expressed by a variety of authors. This paper focuses on the rationale, development, implementation, and evaluation of a consumer health education program for the aged.
