The central assumption of this paper is that, especially in the field of digital technologies to teach and learn mathematics, the influence of the context in which research is carried out has not been given enough attention, so that research results are not really useful outside this context. We base our discussion on the work of a group of European teams carrying out research with a special methodology of “cross-studies” and carrying out “cross-analyses” of particular studies. A context for a research study is described as a dynamic construction by researchers, connecting relevant contextual characteristics in the settings (empirical and academic) where research activity takes place and helping to gain insight from the outcomes of the study. Analyzing the design of two “Didactical Digital Artefacts,” and the associated cross-studies involving teams of three countries, we identify more or less conscious influences of characteristics in the researchers' contexts upon research outcomes. Cross-studies and cross-analysis help to go further by making researchers more aware of their context and of its characteristics. It also helps researchers to “re-contextualize,” that is to say to identify new contextual characteristics in the settings they are acting in, to gain insight from research outcomes that emerged in other contexts. 相似文献

Constructivist, hands-on, inquiry-based, science activities may have a curative potential that could be valuable in a psychological assistance programme for child victims of violence and war. To investigate this idea, pilot sessions were performed in an orphanage located in Ruhengeri, Rwanda, with seven young adults and two groups of 11 children aged from 9 to 16 years. Despite a number of imperfections in this attempt, significant observations have been made. First, a sound communication was established with all, even with the young adults who at the beginning were not as enthusiastic as the children. Furthermore, some children, originally isolated, silent and sad, displayed a high degree of happiness during the activities, and an overall increasing positive change of attitude. In addition, they appropriated well some principles of experimental science. This suggests that a joint development of science literacy and joy may be an interesting approach, both in education and therapy. 相似文献

The use of graphical and symbolic facilities in the teaching and learning of algebra and calculus will soon be a reality.
Authors who write about the introduction of these instruments often claim that new technology is able to redress the imbalance
between skill-dominated conceptions of school mathematics in favour of understanding. More recently some have stressed that
`experimental mathematics' traditionally the reserve of mathematical research may be incorporated into the teaching and learning
of mathematics. This paper looks into these two ideas and shows that they conceal an essential dimension: techniques play
an important role in mathematical activity, intermediate between tasks and theories. This paper draws on research studies
on the introduction of symbolic systems on computers and calculators and considers `new' techniques that accompany new technological
instruments, their role in conceptualising and their links with `usual' paper/pencil techniques, as a key to analyse the role
of technology in education. This view implies non obvious tasks for the teacher in the introduction of technology: the design
of praxeologies adapted to new instrumental settings and everyday action on students' techniques.

Bullying between students in the school setting is an increasing problem. Bullying can be defined as any form of repeated
mental or physical violence carried out by one or several individuals on a person who is not capable of defending himself
(Roland and Idsoe, Aggress Behav 27:446–462, 2001). The aim of this paper is to observe the expression of self-concept and adjustment strategies developed by children subject
to this kind of violence. Five hundred twenty-four students between the ages of 8 and 12 (m = 9.44) participated in the longitudinal study. Two measurements were made during the same school year at an interval of
6 months. The results show that the student victims of bullying present weaker self-conceptions than the control group. Recourse
to avoidance strategies would be dominant among student victims of bullying. Moreover, recourse to “avoidance” type strategies
would lead to an increase in the frequency of bullying while recourse to “approach”-type strategies would lead to a reduction
in it. Furthermore, it would seem that recourse to avoidance strategies at T1 lowers the student’s self-concepts at T2. The
opposite effect is observed with the approach strategies. These different results emphasize the necessity to establish prevention
programs which allow an intervention simultaneously on the level of the school, the family, and the student. 相似文献

We examine teachers’ classroom activities with the spreadsheet, focusing especially on episodes marked by improvisation and
uncertainty. The framework is based on Saxe’s cultural approach to cognitive development. The study considers two teachers,
one positively disposed towards classroom use of technology, and the other not, both of them experienced and in a context
in which spreadsheet use was compulsory: a new curriculum in France for upper secondary non-scientific classes. The paper
presents and contrasts the two teachers in view of Saxe’s parameters, and analyzes their activity in two similar lessons.
Goals emerging in these lessons show how teachers deal with instrumented techniques and the milieu under the influence of
cultural representations. The conclusion examines the contribution that the approach and the findings can bring to understanding
technology integration in other contexts, especially teacher education.

Previous research on Montessori preschool education is inconsistent and prone to analytic flexibility. In this preregistered study, disadvantaged preschoolers in a French public school were randomly assigned to either conventional or Montessori classrooms, with the latter being adapted to French public education. Adaptations included fewer materials, shorter work periods, and relatively limited Montessori teacher training. Cross-sectional analyses in kindergarten (N = 176; Mage = 5–6) and longitudinal analyses over the 3 years of preschool (N = 70; Mage = 3–6) showed that the adapted Montessori curriculum was associated with outcomes comparable to the conventional curriculum on math, executive functions, and social skills. However, disadvantaged kindergarteners from Montessori classrooms outperformed their peers on reading (d = 0.68). This performance was comparable to that of advantaged children from an accredited Montessori preschool. 相似文献

A tube-in-square-pipe microfluidic glass cell has been developed for studying the aggregation and fiber formation from regenerated silk solution by in-situ small-angle X-ray scattering using synchrotron radiation. Acidification-induced aggregation has been observed close to the mixing point of the fibroin and buffer solution. The fibrous, amorphous material is collected in a water bath. Micro-wide-angle X-ray scattering of the dried material confirms its β-sheet nature. 相似文献
