This exploratory study was conducted to illuminate aspects relevant to the emergence and evolution of informal roles in a group during a canoe expedition. Following tenets of ethnography, the first author collected observational and interview (conversational and focus group) data while participating as a member of the expedition. Three general dimensions were revealed with regards to emerging and evolving informal roles: context aspects; role occupant aspects; and group member aspects. Informal roles were found to be important structural components which contributed to group productivity and harmony. Findings are discussed in relation to the broader literature while questions are raised regarding how informal roles have been conceptualized. Implications include considering how informal roles relate to individual (e.g. satisfaction) and group (e.g. cohesion) level constructs and how outdoor leaders may benefit from understanding how informal roles emerge and evolve.  相似文献

This study investigated the role of broad cognitive processes in the development of mathematics skills among children and adolescents. Four hundred and forty-seven students (age mean [M] = 10.23 years, 73% boys and 27% girls) from an elementary school district in the US southwest participated. Structural equation modelling tests indicated that calculation complexity was predicted by long-term retrieval and working memory; calculation fluency was predicted by perceptual processing speed, phonetic coding, and visual processing; problem solving was predicted by fluid reasoning, crystallised knowledge, working memory, and perceptual processing speed. Younger students’ problem solving skills were more strongly associated with fluid reasoning skills, relative to older students. Conversely, older students’ problem solving skills were more strongly associated with crystallised knowledge skills, relative to younger students. Findings are consistent with the theoretical suggestion that broad cognitive processes play specific roles in the development of mathematical skills among children and adolescents. Implications for educational psychologists are discussed.  相似文献

The theoretical basis, the development and the use of an inventory designed to measure styles of learning and motivation are described. On the basis of previous research, items within the inventory were located on 20 sub-scales. The ten motivation sub-scales were derived from a theory of school motivation which was based on extensive interview and inventory work carried out in Hungary with children, their parents and teachers. The ten scales describing styles of learning were derived from concepts describing learning approaches and styles which emerged from interviews and experimental research with students in British and Swedish higher education. Versions were prepared in both English and Hungarian and given to samples of 614 British and 579 Hungarian pupils aged between 13 and 17 years. A remarkably similar factor structure was obtained in each sample. An analysis of mean scores indicated distinctive differences both between boys and girls, and between British and Hungarian pupils. Cluster analysis was used to investigate the possible existence of styles which combined both approaches to learning and aspects of school motivation. The potentiality of the inventory for use in conjunction with study skills courses is discussed.  相似文献

This study was designed to assess whether the effects of computer-assisted practice on visual word recognition differed for children with reading disabilities (RD) with or without aptitude-achievement discrepancy. A sample of 73 Spanish children with low reading performance was selected using the discrepancy method, based on a standard score comparison (i.e., the difference between IQ and achievement standard scores). The sample was classified into three groups: (1) a group of 14 children with dyslexia (age M = 103.85 months; SD = 8.45) who received computer-based reading practice; (2) a group of 31 "garden-variety" (GV) poor readers (age M = 107.06 months; SD = 6.75) who received the same type of instruction; and (3) a group of 28 children with low reading performance (age M = 103.33 months; SD = 9.04) who did not receive computer-assisted practice. Children were pre- and posttested in word recognition, reading comprehension, phonological awareness, and visual and phonological tasks. The results indicated that both computer-assisted intervention groups showed improved word recognition compared to the control group. Nevertheless, children with dyslexia had more difficulties than GV poor readers during computer-based word reading under conditions that required extensive phonological computation, because their performance was more affected by low-frequency words and long words. In conclusion, we did not find empirical evidence in favor of the IQ-achievement discrepancy definition of reading disability, because IQ did not differentially predict treatment outcomes.  相似文献

In this article we describe and interpret how two distinct layers of critical friendship were used to support a pedagogical innovation in pre-service teacher education. The innovation, Learning about Meaningful Physical Education (LAMPE), focuses on ways to teach future teachers to foster meaningful experiences for learners in physical education. Critical friendship was applied in two ways: (1) the first two authors served as critical friends to each other as they taught their respective teacher education courses using LAMPE, and (2) the third author acted as a meta-critical friend, providing support for and critique of the first two authors’ development and enactment of the innovation. Over two years, data were gathered from reflective journal entries, emails, recorded Skype calls, and teaching observations. The two layers of critical friendship held significant benefits in advancing and supporting the development of the innovation while also contributing to the professional learning of all participants. Analysis of the first year’s data showed that we entered the critical friendship without thoroughly considering what we each hoped to give and take from the relationship or acknowledging the potential problems that might unfold. In the second year, guided by suggestions from our meta-critical friend, we took a more rigorous inquiry stance as critical friends, contributing contentious feedback and pushing each other beyond our personal and pedagogical comfort zones. This led to a noticeable improvement in our professional learning about teacher education practices and advanced the development of the LAMPE innovation.  相似文献
