Le Logiciel ‘Derive’ comme revelateur de phenomenes didactiques lies a l'utilisation d'environnements informatiques pour l'apprentissage

In this article, we address the issue of integration of computer environments in the mathematics secondary curriculum, by referring to the results of a research project carried out with the software DERIVE. Firstly, we present the research project and its theoretical framework, secondly, we evidence some didactical phenomenas linked to the DERIVE transposition of mathematical knowledge and learning processes in this environment which, in our opinion, play a crucial role in integration issues.This revised version was published online in September 2005 with corrections to the Cover Date.     

The breadth of peer relationships among preschoolers: an application of the Q-connectivity method to externalizing behavior

Preschoolers' (M(age) = 48.7 months) social breadth (the number of peer children interact with and the frequency of these interactions) and the relations between breadth and externalizing behaviors were examined using the Q-connectivity method. After considering age, sex, and classroom effects on social breadth, children's externalizing behaviors were studied in relation to levels of social breadth across variations in frequency of exposure to peers and to patterns of decline in social breadth. Externalizing preschoolers occasionally interacted with most of their classmates. However, their individual peer networks moderately to rapidly became selective, and they engaged in repeated interactions with a relatively small number of peers. Although there were no sex effects, significant age and classroom effects were obtained.

A Contribution of the Computer to Biology Education at the University

Summaries

English

At the O.P.E. Laboratory, computer‐based biology dialogues result in a new pedagogical situation which could not be achieved by any other method.

This paper describes part of O.P.E. embryology dialogues, designed for undergraduate medical and biology students, and concerning interactions between inductive and competent tissues during embryonic development. Each student using these dialogues is in a position to proceed, in an active manner, through three principal stages in the knowledge of the competence concept: determination of experimental criteria of a state of competence; analysis of evolution of competence in course of time; detection of modifications of competence of a tissue towards sequential inductors.

In the course of the dialogue, each student has to interpret various experimental results, verify hypotheses and conduct in his own way a series of simulated experiments (students have no other chance of carrying out this kind of embryology experiment). The validity of the student's reasoning and his experimental methodology are constantly controlled.

These computer‐based biology dialogues are not intended to supersede other pedagogical activities. They are designed to be a new and specific contribution to comprehension, mastery, and even modelling, of biological concepts and mechanisms, and appear to meet actual requirements of biology education.     

The cubicle warrior: the marionette of digitalized warfare

In the last decade we have entered the era of remote controlled military technology. The excitement about this new technology should not mask the ethical questions that it raises. A fundamental ethical question is who may be held responsible for civilian deaths. In this paper we will discuss the role of the human operator or so-called ‘cubicle warrior’, who remotely controls the military robots behind visual interfaces. We will argue that the socio-technical system conditions the cubicle warrior to dehumanize the enemy. As a result the cubicle warrior is morally disengaged from his destructive and lethal actions. This challenges what he should know to make responsible decisions (the so-called knowledge condition). Nowadays and in the near future, three factors will influence and may increase the moral disengagement even further due to the decrease of locus of control orientation: (1) photo shopping the war; (2) the moralization of technology; (3) the speed of decision-making. As a result, cubicle warriors cannot be held reasonably responsible anymore for the decisions they make.     

The Heuristic for Thinking About Culturally Responsive Teaching (HiTCRiT)

Michèle was hurrying to class. How, she thought, could she offer the students in her African American English in Society and Schools class a method of understanding, comparing, and abstracting the studies they had been reading in class? The heuristic described in this study evolved from a desire to capture aspects of several seminal studies that illustrated how African American English was deployed in classrooms for productive work with African American students. Michèle recalled that whenever she asked graduate students or practicing teachers what they, other teachers, and schools might do to improve the schooling of students of color, one of the most consistent responses was Culturally Responsive Pedagogy (CRP). However, when pressed and asked what one would detect in classrooms where CRP is being put into practice, few were able to specify what an observer might see. Specifying the dimensions of CRP and its relationship to the heuristic had not been on Michèle’s mind. Even so, it was during the class discussion that the heuristic’s relevance to CRP became clearer. Jonathan, who had been tapped as a teaching assistant in an English language arts methods class, believed HiTCRiT could be modified to use with teacher education candidates, as a substitute for the standardized lesson planning tool used in the department. He piloted its use with the class the following semester. Utilizing HiTCRiT to explain research and existing practices as well as to assist teachers in creating culturally relevant instruction modified and shaped it, creating a more robust tool. Thus, the HiTCRiT came into being and came to inform our thinking and teaching practice.
