We will attempt a synthesis from various research perspectives that have analyzed the alterations that knowledge inevitably goes through while percolating into classroom activities. We will try to identify some of their causes and will illustrate them with examples in genetics. First, we will discuss some research on knowledge transformation when genetics knowledge is popularized (Staerklé and Clémence 2002), to show how knowledge is transformed in specific predictable manners as it moves from experts to general public. Then, we will draw from a large body of (French) research in didactic transposition (Chevallard 1991) in order to highlight what knowledge characteristically thrives or is lost as it percolates into school practice and learner’s knowledge. We will then draw from Huberman’s (Science Communication, 4(4), 478–510, 1983) analysis of knowledge use in schools the specificities of knowledge that teachers effectively use. All three perspectives reveal that cognitive and social environment are crucial determinants of what knowledge will be found in schools. An ecological metaphor explains how different cognitive environments from research into education favor knowledge adapted to specificities of this ecosystem. This transposition of knowledge is therefore not decay but inescapable and necessary. Ignoring this transposition has considerably reduced the effectiveness of many educational reforms. We will combine these three to propose an evolutionary perspective that could inform ways of expressing research into educational recommendations fed into the system to optimize the didactic transposition process. 相似文献
In the research reported in this article, we sought to understand the instructional practices of 26 secondary teachers from one district who use a problems-based mathematics textbook series (Core-Plus). Further, we wanted to examine beliefs that may be associated with their instructional practices. After analyzing data from classroom observations, our findings indicated that the teachers’ instructional practices fell along a wide continuum of lesson implementation. Analysis of interview data suggested that teachers’ beliefs with regard to students’ ability to do mathematics were associated with their level of lesson implementation. Teachers also differed, by level of instructional practices, in their beliefs about appropriateness of the textbook series for all students. Results strongly support the need for professional development for teachers implementing a problems-based, reform mathematics curriculum. Further, findings indicate that the professional development be designed to meet the diverse nature of teacher needs. 相似文献
Gagnon and Doré (1992) showed that domestic dogs are able to solve a Piagetian object permanence task called the invisible displacement problem. A toy is hidden in a container which is moved behind a screen where the toy is removed and left. Dogs make more errors in these problems than they do in visible displacement tests, in which the object is hidden directly behind the target screen. In Experiment 1, we examined components of the standard procedure of invisible displacements that may make encoding or retention of the hiding location more difficult than it is in visible displacements. In Experiment 2, we compared dogs’ performances in visible and invisible displacement problems when delays of 0, 10, and 20 sec were introduced between the object’s final disappearance and the subject’s release. The results revealed that dogs’ poorer performance in invisible displacement tests is related to the complex sequence of events that have to be encoded or remembered as well as to a difficulty in representing the position change that is signaled, but not directly perceived. 相似文献
Infants’ abilities to focus attention on objects are known to be related to mothers’ mobilizing behaviors. As delayed effects of maternal behaviors at 5 months may be observed in 8-month-olds, mothers may be considered as scaffolding their infant’s attention. However, all dyadic activities are probably not equally propitious to attention mobilizing. In a sample of 30 dyads, studied at 5 and 8 months of age, whole observations were split in four broad categories: care, dyadic play with objects, dyadic play without objects and infant alone. The duration of maternal mobilizing and infant attention focussing were studied within categories. Inter-dyads variability is high, while dyads are stable across ages. Even within the dyadic play with objects, mothers differ widely in the duration and way they mobilize attention. Five-month-olds still need their mother’s support, as they explore less when they are alone, while 8-month-olds are more autonomous. The impact and importance of the various types of dyadic activities on cognitive development are discussed. 相似文献
Prior to large experimentations on the teaching of probability theory, it appeared useful to observe some students working for a fairly long time. This observation should make more precise the difficulties of an important aspect when solving probability problems: the modelling aspect. Does systematic use of simulation produce miracles as it is sometimes said? Are the students naturally sensitive to a frequentist approach of probability theory? This paper contains some results on these questions, for example we pointed out for some students an obstacle to the frequentist approach. The results permit to conceive how using simulation for teaching could contribute to an improvement of students' approach to probability. 相似文献
This study examined how intergroup processes and social-cognitive factors shape bystander responses to bias-based and general bullying. Participants included sixth and ninth graders (N = 179, M = 13.23) who evaluated how likely they would be to intervene if they observed bullying of immigrant-origin and nonimmigrant-origin peers. Adolescents’ grade, intergroup attitudes, and social-cognitive abilities were evaluated as predictors of bystander responses. Nonimmigrant-origin adolescents reported that they expect they would be less likely to intervene when the victim is an immigrant-origin peer. Furthermore, participants with more intergroup contact and higher theory of mind were more likely to expect they would intervene in response to bias-based bullying. Findings have important implications for understanding factors that inform antibullying interventions that aim to tackle bias-based bullying against immigrants. 相似文献
This study investigated relationships between career adaptability and personality and pathological traits using the network analysis approach. We administered CAAS, BFI-2-S, and IDCP-2 to 630 working adults. We observed positive associations between personality and career adaptability and negative associations between pathological traits and career adaptability. This paper contributes to the understanding of the associations between career adaptability and Big Five personality traits and pathological traits. We found stronger associations between career adaptability and personality traits as compared to pathological traits. Our findings suggest that Neuroticism and Conscientiousness contribute more to adaptation to professional development tasks than do pathological traits.
AbstractPart-time teachers form a growing proportion of the global Higher Education (HE) workforce. Their backgrounds can vary from Graduate Teaching Assistants (GTAs) teaching for the first time, to practitioners bringing workplace experience into HE and sessional teachers, all with differing professional development needs. This paper builds on previous research to consider structures and practices promoting sustainable, effective professional development for part-timers, to propose proactive holistic professional development, and raise institutional awareness of the challenges of reaching part-timers. A case study exploring the lived experiences of part-time staff illustrates key features of part-timers’ preparation for their current work and future aspirations. 相似文献
We investigated the effects of college training on students’ metatextual knowledge, hypertext navigation strategies and their
acquisition of problem-relevant information. Ten psychology undergraduates and nine clinical psychology post-graduate students
were asked to study a 3,400-word, 14-section hypertext with the purpose of drafting a short essay on a specific, complex issue
in the area of teenage psychopathology. The specialists outperformed the novices on a metatextual knowledge test. They spent
more time visiting relevant sections of the hypertext, and wrote essays containing more critical information. They also displayed
a better incidental memory for the hypertext structure. We discuss the data in terms of the late acquisition of metatextual
knowledge and study strategies. 相似文献
