This article focuses on the case study of the concept of covalent bonding for 10th grade pupils in France. On the basis of their conceptions and difficulties, didactical engineering has been established that should lead to an improvement in the understanding of this concept. After analyzing the pupils' difficulties, we reflected on the…

Numeration units (ones, tens, hundreds, etc.) are an epistemological foundation for place value. Here, we assume that they are a didactic support in countries where spoken numbers are incongruent with written numbers. In France, teaching practices neglect the relations between units, and numeration units are typically used only to designate the…

The experiment that we present in this paper explores the teaching of Galilean motion principles observed in different reference frames, in an astronomical context. All grade 10 students in a French high school (the lycée Condorcet, Val de Marne) participated in two successive teaching-learning sessions, designed within the theoretical framework…

This paper examines the existence and impact of theoretical mathematical foundations on the teaching and learning of whole numbers in elementary school in France. It shows that the study of the New Math reform--which was eventually itself replaced in the longer term--provides some keys to understanding the influence of mathematical theories on…

In many situations, the change in the conceptual understanding of students is measured using a single question. This is, for instance, the case in peer instruction where students answer twice to the same questions, before and after the discussion phase. Using item response theory and assuming that students proficiencies are normally distributed,…

Certain mathematical concepts were not introduced to solve a specific open problem but rather to solve different problems with the same tools in an economic formal way or to unify several approaches: such concepts, as some of those of linear algebra, are presumably difficult to introduce to students as they are potentially interwoven with many…

This study investigated the use of digital learning objects in elementary and secondary schools. The specific objectives were: a) to identify the frequency with which learning object are used by teachers, the type of object most frequently used, the teaching strategies that is more frequently adopted, the main reason for the use of learning…

This paper examines the resulting qualitative transformation of two students' metapragmatic awareness following a semester abroad in southern France--one of whom had access to a concept-based pragmatics instruction programme (expert-mediation), while the other followed a standard semester programme. The larger study from which these cases are…

From the early nineties, most reformed curricula at upper secondary level choose to give functions a major position and a priority over rational expressions and equations of traditional algebra. The goal of this paper is to introduce key challenges resulting from this choice and to discuss the contribution that software environments associating…

The present study takes an interdisciplinary mathematics-physics approach to the acquisition of the concept of angle by children in Grades 3-5. This paper first presents the theoretical framework we developed, then we analyse the concept of angle and the difficulties pupils have with it. Finally, we report three experimental physics-based teaching…

Institutional relations to knowledge objects at the primary school are time-fluctuant and therefore closely linked to the development of institutions. Building up the concept of material implies several sciences and technologies in overlapping epistemological fields. The questions of transposition and appropriation associated to the concept at…

Today's method of teaching the concept of falling bodies in French physics classes is ineffective, not only because it ignores the physical aspect of the phenomenon by addressing only its mathematical aspect, but also because it does not take into account students' initial conceptions, which are often incompatible with scientific knowledge. The…

Proposes a methodology for teaching comprehension of a foreign language in both the reading and the listening domains. (Text is in French.) (TL)

This subunit on Western Europe is one of four resource units for an eleventh grade area studies course. One section of the subunit contains an introduction and the other the geography of Western Europe. The introduction contains objectives, an outline of content, teaching procedures, and instructional materials. The geography section focuses upon…

The four 1986 issues of the journal on suggestive and accelerative learning and teaching (SALT) include articles on these topics: SALT components in English composition instruction; music therapy for moderately retarded students; the brain and accelerated learning; accelerated learning and self-concept; remedial reading; versions of the concert…
