Abstract

The purpose of our study was to carry out a writing workshop in a collaborative setting in which the teacher and the 14 year-old students made up stories while being observed by a researcher. We used a qualitative methodology similar to the Ethnography of Communication and Discourse Analysis, in which narrative and analytical analyses are seen as complementary, in order to interpret all aspects of the participants’ activities. The analysis of the conversations held in the different working situations defined by the presence or absence of the teacher shows that the guiding role played by the teacher is essential in terms of the students’ acquisition of knowledge concerning the generalization of meanings, the organization of social relations and the structuring of the task. Likewise, within a group of peers involved in working towards a common goal, one or several of them tend to take on the guiding role when the teacher is not present.  相似文献

Rats were used in four experiments to study the effects on behavior and pain sensitivity of exposure to a context previously paired with footshock or injection of the emetic drug lithium chloride (LiCl). Exposure to a context previously paired with footshock or injection of LiCl provoked the species-typical defense response of freezing (Experiments 1A and 1B). Exposure to a context previously paired with footshock additionally produced hypoalgesia when rats were tested using the tailflick test (Experiment 1A). By contrast, exposure to a context previously paired with injection of LiCl produced hyperalgesia when rats were tested using the tailflick test (Experiment 1B). However, exposure to a context previously paired with injection of LiCl did provoke hypoalgesia when rats were tested for pain sensitivity using either the hotplate or formalin tests (Experiment 2), which was mediated by the release of endogenous opioid peptides (Experiment 3). These results are discussed with reference to the processes governing associative regulation of defensive behavior and pain control.  相似文献

In Russia a new school subject has been introduced in order to facilitate educators in shaping the enculturation process of the autonomous student into the cumulative tradition. In this article the Russian societal and educational context is described and the concepts ‘religion’ and ‘culture’ are clarified. Together they build the concentric structural model in which a distinction is drawn between different layers representing various influential factors related to RE, not only in Russia but also in the western world. In our view this concentric structural model is constitutive for the new school subject of religious culture. The presentation of the model and its application is central in this article.  相似文献

This article is an initial evaluation of a motor skills assessment for primary aged children. The Manchester Motor Skills Assessment (MMSA) is designed to be quick and easy for teaching assistants to complete, with the dual purposes of informing group programme planning and demonstrating an individual child’s progress following a period of intervention. Inter‐rater reliability checks were conducted during initial assessments of 37 children in 11 schools. Focus groups discussed practical relevance of the tool. The evidence from this small‐scale study suggests that a range of assessors can reliably complete the MMSA. The tool also taps into functionally relevant motor skills for primary age children and informs programme planning. The MMSA appears to be a promising tool for supporting primary schools in identifying children with motor skills difficulties. The contribution of EPs to the MMSA’s development and implementation is discussed.  相似文献

This study investigated relations between preschoolers’ emergent executive function skills and their interactions with parents, with particular focus on the verbal utterances parents use to guide children's behavior (i.e., management language). Parent–child dyads (n = 127) were videotaped during a structured play task and the frequency of two types of management language, Direction (high control) and Suggestion (low control), was observed. Children's executive function was assessed using the Head–Toes–Knees–Shoulders (HTKS) task. Latent growth modeling was used to investigate relations between management language and the development of children's executive function. Direction language (i.e., commands) was negatively associated with children's age three executive function but not significantly related to the rate of executive function development over time. Conversely, Suggestion language (i.e., questions and statements that offer children some degree of choice) was positively related to executive function at age three but negatively related to growth. The potential importance of management language as a parenting behavior that contributes to various aspects of children's self-regulation during preschool and kindergarten is discussed.  相似文献

Problem solving is generally regarded as the most important cognitive activity in everyday and professional contexts. Most people are required to and rewarded for solving problems. However, learning to solve problems is too seldom required in formal educational settings, in part, because our understanding of its processes is limited. Instructional-design research and theory has devoted too little attention to the study of problem-solving processes. In this article, I describe differences among problems in terms of their structuredness, domain specificity (abstractness), and complexity. Then, I briefly describe a variety of individual differences (factors internal to the problem solver) that affect problem solving. Finally, I articulate a typology of problems, each type of which engages different cognitive, affective, and conative processes and therefore necessitates different instructional support. The purpose of this paper is to propose a metatheory of problem solving in order to initiate dialogue and research rather than offering a definitive answer regarding its processes. This paper represents an effort to introduce issues and concerns related to problem solving to the instructional design community. I do not presume that the community is ignorant of problem solving or its literature, only that too little effort has been expended by the field in articulating design models for problem solving. There are many reasons for that state of affairs. The curse of any introductory paper is the lack of depth in the treatment of these issues. To explicate each of the issues raised in this paper would require a book (which is forthcoming), which makes it unpublishable in a journal. My purpose here is to introduce these issues in order to stimulate discussion, research, and development of problem-solving instruction that will help us to articulate better design models.  相似文献
