The impact of environmental factors on components of reading and dyslexia

Data from 123 male adults were analyzed to estimate environmental influences on components of literacy skills and to explore the impact of environmental factors in different approaches to define reading difficulty. Literacy skills were decomposed into general cognitive function, reading comprehension, spelling, word reading, and phonological ability. Environmental factors examined were related to home conditions, school conditions, and literacy environment. Results suggest that there is a substantial social-cultural bias in the delineation of literacy skills and in the definitions of reading disabilities. Results also suggest that phonological ability constitutes the only measure relatively unaffected by environmental influences. This study has brought forward a new argument for emphasizing phonological deficits as the core component in defining dyslexia.     

PROSPECTIVE TEACHERS�� INITIAL CONCEPTIONS ABOUT PUPILS�� DIFFICULTIES IN SCIENCE AND MATHEMATICS: A POTENTIAL RESOURCE IN TEACHER EDUCATION

A crucial issue for prospective teachers (PTs) in their education is to develop pedagogical content knowledge (PCK; i.e. how to make a topic comprehensible to pupils). However, research has shown that PTs may have tacit ideas about teaching that act as filters preventing consideration of unfamiliar and discrepant ideas. These ideas must be elicited and taken into consideration in order to be modified. Therefore, PTs’ explicit conceptions may constitute a valuable resource in teacher education. The aim of this study was to investigate PTs’ ideas about pupils’ difficulties, at a topic-specific level, upon beginning the teacher education programme. The “Lesson Preparation Method” was used in four case studies to elicit the conceptions of 32 PTs regarding pupils’ difficulties in four specific science and mathematics topics: plant growth, gases, equations and heat and temperature. In all four topic groups (n = 5 – 11), there was a variety of initial conceptions about pupils’ difficulties, which were categorised into two to five topic-specific categories. Although, initially, PTs may not have expressed any notions about pupils’ difficulties, conceptions were elicited by using the Lesson Preparation Method. Furthermore, we found that the initial ideas corresponded with earlier research on pupils’ difficulties, which could provide a potential resource when creating a scaffolding context in teacher education programmes where PCK development is stimulated.     

Curriculum Material Development in a Small Society

Abstract

This article reviews curriculum material development for the compulsory school level in Iceland, the responsibility of the National Centre for Educational Materials (NCEM), a new governmental organization. A brief survey is given of the institutions antecedent to the NCEM, and the organization of the NCEM is described as well as its major activities and future emphasis.     

Reading Skill and the Processing of Text Structure

Backman, J., Lundberg, I., Nilsson, L.‐G. & Ohlsson, K. 1984. Reading Skill and the Processing of Text Structure. Scandinavian Journal of Educational Research 29, 113‐128. Oral reading speed, free recall and summarization of narrative stories presented on videotex were studied as a function of reading skill, text structure and physical factors such as paragraphing and color cueing of clauses on various levels of importance. A total of 144 subjects (13‐14 years old) participated in the experiment, half of them being rated as poor readers and half as good readers. Good readers outperformed poor readers on all dependent variables. Important propositions were better recalled and were more often included in summaries than less important parts of the texts, especially if they were signalled by a different color. However, the impact of graphical cueing depended on reading skill, text type and task. The interactions were discussed in terms of differences in processing strategies and prior knowledge.
