Roditi, Éric. "L' enseignement de la multiplication des décimaux en sixième : étude de pratiques ordinaires". Paris 7, 2001. http://www.theses.fr/2001PA070089.
Texto completo da fonteThis thesis presents four different teaching experiences concerning decimal multiplication in sixth grade, ail carried out in similar circumstances. The analysis is based on transcriptions made from recordings of the lessons, as well as interviews with the teachers concerned. It studies the preparation which went into the observed lessons and the results in the classroom. It uses a double approach: the first applies didactics of mathematics to the observed teaching experiences in order to analyze the potential learning effectiveness of the experiences. The second approach borrows a few elementary theories from the field of ergonomic psychology and assumes the coherence of the teaching practices to study teachers as individuals in a real-life teaching environment. The studied teaching experiences ail demonstrate certain restraints imposed by two factors: working in a school institution and working with real pupils, with ail the problems inherent to this situation, notably as regards class and time management. These restraints explain, on a macro level, the similarities of the four experiences. There is, however, beyond these restraints, a certain amount of individual decision-making that the observed teachers were using. This factor explains, on a micro level, the pedagogical diversity seen in these four classes. These experiences differed according to the teaching strategy of each individual teacher, the tasks given to the pupils and the organization of the knowledge institutionalization. The activities of the pupils differed greatly from one teaching sequence to another, especially depending on whether the goal was to increase the knowledge and understanding of the pupils or simply to have them apply a certain technique. Likewise, the questions students asked as well as their interactions with the teacher varied greatly. Nevertheless, in numerous cases, a cross-analysis tended to confirm that, for each teacher, a coherent teaching practice exists

Texto completo da fonteProcedural generation is a method widely used in video games to deliver varied content tailored to players. However, this method is rarely used in the field of Technology Enhanced Learning (TEL). In this PhD thesis, our focus is on the generation of game activities for declarative knowledge training (i.e., factual information such as laws and multiplication tables). In this context, it is necessary to provide learners with varied and adapted activities to avoid task drop-out caused by boredom. The scope of this thesis covers three angles of adaptation: the teacher's perspective on training, learner-players progression and players preferences.This PhD work falls within the field of engineering research of TEL systems. The aim is to characterise the generation of activities and to propose a “generic” approach, i.e., independent of any specific didactic domain. Thus, the aim is to be able to reuse generation elements for different domains. This thesis is based on the AdapTABLES research project, which provides an initial ground of study and experimentation. The aim of this project is to design and develop a multiplication table training game. The research contribution (i.e., study and design methods) was developed in this context, but was also generalised and evaluated in other contexts.First, we identified a game genre compatible with declarative knowledge training: the Roguelite. In this game genre, the activities or game levels are procedurally generated and incorporate a high degree of variability. Repetition is encouraged by a “permanent death” mechanism. Then, we: 1) characterised and specified the generation by analysing the different adaptation needs (i.e., teacher, learner-player) and 2) proposed a framework (i.e., conceptual framework and software infrastructure) based on the principles of Model-Driven Engineering to design and implement generators for declarative knowledge training in the context of Roguelite oriented games. The generators designed are independent software components producing levels (i.e., dungeons) in XML format that can be interpreted by an educational game.Three generators have been designed using the framework: one for multiplication training, a second for history and geography facts (i.e., required for the Diplôme National du Brevet des Collèges, a French exam taken in 9th grade) training, and a third for judo facts training. The multiplication tables generator is currently being used in an educational game designed as part of the AdapTABLES project. The framework and its components have been validated using system tests and model checking, as well as experimentation with an engineer to assess the usability of the framework. Moreover, the game developed for the AdapTABLES project and the associated generator were used several times in ecological conditions

Texto completo da fonteThe work begins with a historical and comparative approach to theories on games and their function in education, and a reflection on the problematics of teaching arithmetic to primary school children. There then follows an elaboration of specifics games. A first game "vamos aprender matemática". Based on a traditional format and intended for the Portuguese market, led to the development of a second, computer game, "la spirale". These two games form the basis for an evaluation of the progress of children in arithmetic, and on the relationships between mathematical competence and the observed strategical ability of the children involved

Texto completo da fonteTurning out a numerical answer to a problem that cannot be put into figures (i. E. "âge du capitaine") is a result of the didactic contract ; it appears to be closely linked to the situations of creation and cannot be attributed to a dysfunction of the didactic relation or to a lake of linguistic capacities. In a similar situation, the various answers provides are proof to different approaches as regards the didactic contract. The background of this contract mainly consists of the teaching methods at school and the education given at home together with the values and principles of the teaching system : this background is the very explanation of these differences in the approaches

Texto completo da fonteThe object of this research is the development of proving in the pupils' productions when they resolve arithmetical problems at the end of primary school (9-11 years old). The experimentation was carried out for several years through the elaboration of a didactical engineering in schools situated in defavorised areas. Three axes are chosen : the pupils' argumentations and proofs, the nature of problems, the didactical situations' variables and teachers' management of collective moments. The theorical part of this research is based upon the theory of didactical situations, and on works about proof and argumentation, especially Balacheff and Duval's ones. It allows an analysis of proofs during the primary school : exhaustive proofs, counterexamples and reasoning laid upon knowings. The construction of a new typology of proofs, after the experimentation, allows us to analysis the productions of proofs and their evolutions (concerning proceedings, properties and justifications). A comparative analysis of two sequences, about a same problem, at the beginning and at the end of the elaboration of a situation, shows the importance of the formulation moments. The analysis of the leading by the teacher of collective moments in ordinary teaching sequences precises the relation between favorable linguistic and socials pratics and thé proving process. It asks the gestion of institutionalization in this kind of situations

Texto completo da fonteModular multiplication is the main operation in most of asymmetric cryptography protocols (Diffie-Hellman key exchange, RSA, ECDSA). Thus hardware implementation of this operation needs attention. In this work, we propose a hardware implementation of modular multiplication for an ASIC target. We consider two levels of scalability : - Implementation must fit any chip area - Design must be reused for different sizes of moduli. After an algorithmic study we show why Montgomery algorithm is preferred. Then this algorithm is studied in details in order to proceed at its hardware implementation. Strategy used for implementation consists in minimizing the number of kinds of elementary operation in the algorithm. Then we obtain a family of scalable hardware improving time-area tradeoffs in comparison to previous scalable hardware. Then considering the hardware developed as a "black-box", we show how to perform modular reduction with this hardware. We also study how to add an additive countermeasure against DPA attacks with a slow extra-computational time (less than 5%). Finally, a Montgomery algorithm using Fourier representation is studied with an asymptotic cost in O(nlog(n)) but inefficient for practical application

Texto completo da fonteOur study began with the notion that multiplication is a complex mathematical object, in both its epistemological and cognitive dimensions. The fact that geometric representations can make a mathematical object's meanings more obvious led us to structure our research around the geometrization of multiplication for different sets of numbers. To study the relationship between this complex mathematical object -- multiplication -- and the construction of meaning by students we designed experimental lessons that were put in place in French high school and junior high school classrooms. This experimental study allowed us to closely analyze students' understanding of the topic, or, on the other hand, the obstacles they encountered in a mathematics assignment requiring frame changes and changes in registers of semiotic representation. Our experimental data were analyzed using a combination of several theoretical approaches. The notion of the Mathematical Work Space and its geneses allows us to account for the complexity of students' mathematical work. In order to study collaborative work between students, as well as the teacher's role in this process of cultural mediation, we also applied theories of semiotic mediation and the social construction of knowledge. Our resulting theoretical framework allows us to give a detailed description of the relationships between the epistemological and cognitive levels of the MWS. We conclude with the identification and analysis of individual students' chosen paths, resulting from interactions within a Mathematical Work Space

Texto completo da fonteIn France, the concepts of ratio and proportion have disappeared from secondary education syllabuses since 1970, when the linear function was supposed to reformulate the proportionality between magnitudes. But in the new organization of teaching contents, the linear function is only an example of a numerical relation, so that nowadays people teaching at any level of education can neither use the linear function nor ratios and proportions to deal properly with elementary arithmetic problems. Looking for a logical and functional articulation of the notions of numbers, variables and functions for a long term learning process emphasizes the fact that dealing with the environment of magnitudes through the practice of ratios, measures and proportionality is absolutely necessary in the genesis of these concepts. Today, French compulsory education, mainly concerned with pupils' future schooling tends to ignore the notions that used to have a strong status in the organisation of a mathematical knowledge which is still in use in popular culture and the working world. Giving up the concepts of ratio and proportion has not been compensated by the expected supplementary steps necessary as much for school institutions as for social and professional institutions. The sense of failure felt by society following this conceptual break from the knowledge of proportionality can't be solved by any pedagogical or psychological remedy. The various institutions involved have to treat this problem by a scientific, technical and political approach with “micro” and “macro” didactical knowledge, the ignorance of which has probably been one of the causes of the difficulties generated by the successive reforms
