Socio-Demographic Vulnerability of Youth
2008
For a kind of inertia effect, the Italian welfare state protects today the old age too intensely while little the new risks associated with other phases of life course. Young Italians seem to suffer the actual changes: “youth remain longer in parental home and postpone the creation of its own independent life to most advanced age”. To understand the vulnerability situation increasingly widespreading among young people, it seems more and more necessary the depth analysis of the reasons and the subjective status of this discomfort that occur through a delay in transition to adulthood. In particular we study the self-perceived vulnerability situation of young Italians in the labor market (both…
The role of mothers' beliefs in students' self-concept of ability development
2018
The aim of this study was to investigate whether the child-related competence beliefs of mothers are associated with the development of Finnish adolescents' self-concept of mathematics and literacy ability during their transition from primary to lower secondary school and whether these associations depend on adolescents' level of performance. The results showed that, first, adolescents' self-concept of mathematics and literacy ability decreased over time. The impact of maternal beliefs on the linear trend of the self-concept of mathematics and literacy ability was dependent on the level of students' performance. Mothers' high beliefs buffered against the decrease in adolescents' self-concep…
The development of work values during the transition to adulthood : A two-country study
2017
This study addresses the development of work values—the desired characteristics of one's current or future job—during young adulthood. Using two panel studies from Germany (N = 2506) and Finland (N = 1326), we investigated (a) mean-level and rank-order change and stability in work values across three biennial waves (age 20/21 to age 25/26); and (b) the influence of stable background characteristics as well as of major transitions in family and work roles on inter-individual differences and intra-individual changes in work values. Latent measurement models with three work value dimensions showed good fit in both countries: extrinsic (importance of job security and material rewards), intrinsi…
Discussing Mathematical Learning and Mathematical Praxeologies from a Subject Scientific Perspective
2018
International audience; This programmatic contribution discusses the link between concepts from Anthropological Theory of Didactics (ATD) and the “subject-scientific point of view” according to Holzkamp (1985, 1993). The main common concern of ATD and the subject-scientific approach is to conceptualize and analyse “objects” like “institutionalized mathematical knowledge” and “university” not as conditions that cause reactions but essentially as meanings in the sense of generalized societal reified action possibilities. The link of both approaches is illustrated by the issue of “real numbers” in the transition from school to university: Hypotheses are derived for further actual-empirical res…
Occitanie, Haute-Garonne, Grenade, Le Castelet
2019
Le lieu-dit Le Castelet à Grenade (Haute-Garonne) est situé à égale distance (1,5 km) du confluent Hers-Girou vers l’est et d’un méandre de la Garonne vers le nord-ouest. Un projet de carrière de la Société Midi-Pyrénées Granulats a permis de retrouver dans ce lieu les traces de plusieurs occupations humaines, échelonnées pour l’essentiel entre le Néolithique moyen et de la fin de l’âge du Bronze. L’ancien réseau hydrographique secondaire de la Garonne marque le paysage et draine dans le sous-sol la nappe phréatique, constituant sans doute un atout. En effet, il suffit de creuser un puits au sein d’un paléo-chenal pour créer un point d’eau au milieu d’une plaine cultivable, et réunir ainsi …
From single to multi-variable Calculus: a transition?
2018
International audience; We recently used the notion of praxeology from the Anthropological Theory of the Didactic to model the knowledge that is necessary for students to learn in order to succeed in an undergraduate multivariable Calculus course. We considered the presence and absence of elements of the knowledge to be taught, as proposed by curricular documents, in the knowledge to be learned, as indicated by final exams. Our results indicate that the mathematical activities expected of students at this level align with the activities observed in differential and integral Calculus, where exercise-driven assessments set students' work mainly in the recognition of types of tasks and recolle…
A study of transitions in an undergraduate mathematics program
2018
International audience; In this paper, we introduce an in-progress study of the transitions students face as they advance in their mathematics courses. Previous work has discussed the changes that occur in the transition from high school to university. With regards to the knowledge students are expected to learn, however, significant similarities have been noted: to do well in introductory university courses, students can learn to solve a particular subset of tasks through routinized techniques, with limited awareness of the supporting mathematical theory. In contrast, students in advanced courses are required to work with and on that theory. The first stage of our project aims to better un…

’Civilising’ the Transitional Generation: The Politics of Civic Education in Post-Communist Romania
2019
Abstract The paper examines the introduction of civic education in post-communist Romania as an educational means of civilising in a democratic ethos the children of the transition. Particularly close analytical attention is paid to a) the political context that shaped the decision to introduce civic education, b) the radical changes in both content and end purpose of civics brought about by educational policies adopted for accelerating the country’s efforts of integrating into the Euro-Atlantic structures (NATO and the European Union), and c) the actual consequences that these educational policies betting on civics have had on the civic values expressed by Romanian teenagers. The analysis …
