There have been numerous anecdotal reports of an improvement in reading in dyslexic children fitted with tinted spectacle lenses. Few of these cases have been subjected to any sort of scientific scrutiny. We report the findings in two dyslexic brothers each of whom showed a marked improvement in reading facility when reading print material either through a semi-transparent tinted plastic sheet (overlay) or through tinted spectacle lenses. Other observed effects of the tinted overlays and/or tinted lenses were improved visual acuity, improved figure/ground perception and reduction in apparent distortions and fragmentation of print. Such improvements were noted in either one or both of the boys. A speculative explanation for this effect is that the lenses act by altering the transmission of impulses along the primary visual pathway.  相似文献

Serial naming speed and its association with reading ability was examined in a longitudinal investigation. Participants were 68 children aged between 4.0 and 4.5 years when the study began and between 5.0 and 5.5 years when the study ended. Serial naming speed was measured at three equidistant time points over the 12‐month period as children progressed from a pre‐literate to early‐literate stage. Children's responses were digitally recorded to computer to enable analysis of the sound files. During analysis, the articulation time for each word and the length of each pause between the spoken words were measured independently. At the end of the study, children's word‐level reading ability was measured. Results suggest that children aged 4.0 to 5.5 years show wide variability in serial naming speed that is predominately attributable to the length of the pauses between the articulated words. There appears to be a developmental association between the duration of the pauses and word‐level reading ability.  相似文献

In the summer of 2014, students from universities in the contiguous United States (Lower 48) and Inupiat youth from Alaska carried out a pilot project as participants/co-researchers in a process called Intergenerational Dialog, Exchange, and Action (IDEA). This action-oriented, community-based, and participatory research method was first developed in 2008, as a platform for structuring dialog between adults, Elders and youth within a community, and for extending resonant ideas emerging from these discussions through Photovoice and digital storytelling amongst youth participants. This pilot study was designed to investigate the feasibility and potential of university students from the Lower 48 and Indigenous youth from Alaska to carry out the IDEA process together as co-researchers. The results of the pilot suggest that it is both possible and meaningful for IDEA to be conducted by a team of youth co-researchers. We found that participation in IDEA expanded the perspectives of youth co-researchers from both Alaska and the Lower 48 in parallel, yet different ways. Exploring the strengths of older community members, being exposed to different ways of living and being, and having opportunities to reflect on and build narratives around these ideas, allowed all the co-researchers to develop a new understanding of their own communities and their roles and responsibilities within them. This paper shares youth co-researcher reflections of the process and the ways in which the process prompted these new perspectives about themselves, their respective communities and their roles within them.  相似文献

Enhancing the quality of argumentation in school science   总被引:1,自引:0,他引:1  
The research reported in this study focuses on the design and evaluation of learning environments that support the teaching and learning of argumentation in a scientific context. The research took place over 2 years, between 1999 and 2001, in junior high schools in the greater London area. The research was conducted in two phases. In phase 1, working with a group of 12 science teachers, the main emphasis was to develop sets of materials and strategies to support argumentation in the classroom, and to support and assess teachers' development with teaching argumentation. Data were collected by video‐ and audio‐recording the teachers' attempts to implement these lessons at the beginning and end of the year. During this phase, analytical tools for evaluating the quality of argumentation were developed based on Toulmin's argument pattern. Analysis of the data shows that there was significant development in the majority of teachers use of argumentation across the year. Results indicate that the pattern of use of argumentation is teacher‐specific, as is the nature of the change. In phase 2 of the project, the focus of this paper, teachers taught the experimental groups a minimum of nine lessons which involved socioscientific or scientific argumentation. In addition, these teachers taught similar lessons to a comparison group at the beginning and end of the year. The purpose of this research was to assess the progression in student capabilities with argumentation. For this purpose, data were collected from 33 lessons by video‐taping two groups of four students in each class engaging in argumentation. Using a framework for evaluating the nature of the discourse and its quality developed from Toulmin's argument pattern, the findings show that there was improvement in the quality of students' argumentation. This research presents new methodological developments for work in this field. © 2004 Wiley Periodicals, Inc. J Res Sci Teach 41: 994–1020, 2004  相似文献

In this paper, we look backwards to educational development principles and practices as implemented in the 1990s at Chalmers University of Technology, Sweden, and forward to ideal principles and practices for the design of courses for teachers in higher education. The bridge between the two lies partly in an evaluation study, which we will describe, and partly in the theoretical work of John Bowden on knowledge capabilities for learning for an unknown future. The underlying framework depends on phenomenography, with its theoretical emphasis on learning as becoming able to discern the whole from its background, and how the constituents of the whole relate to one another and to the whole, and its empirical emphasis on qualitative variation in the ways in which students understand, conceptualize or experience phenomena they meet in their studies. A PET model and PET process are described, relating Practice, Experience and Theory through reflective problematization.  相似文献

In a course on composite materials for fourth-year students at Chalmers University of Technology, students are required to write journals as a complement to the more traditional teaching approach. The journals comprise a series of reports relating the theory currently being treated to an application object, and are sent to the teacher by e-mail for comments. These give the students the opportunity to make use of the theoretical knowledge they meet in each section of the course by reflecting on how it is applicable to a real application. The goal is for better, more integrated understanding, in that, on the one hand, the students should understand the importance of each part of the course and, on the other hand, they should be able to relate the parts to one another, and to practical application. In this paper, we describe the goals and strategies of the change to teaching, we analyse the ways that students approach the journal writing task and we discuss ways in which the journals can improve the quality of student learning.  相似文献

Women consistently remain underrepresented in senior academic roles within the academy worldwide. Academics increasingly require research funding to conduct research, leading to publications, both of which can then be used for promotion applications. This article explores fourteen academic women's experiences of the research funding process in New Zealand, to provide insights into one aspect of why this inequity continues. The findings identify institutional, personal, and funding issues that impact on women's application behaviour. Addressing these may assist in developing women's careers as academics and provides us with a more in-depth understanding of the issues than have previously been gleamed from large quantitative studies.  相似文献
