The effects of reading speed and reading patterns on the understanding of text read from screen

With increasing use of the World Wide Web, rapid scanning or skimming of material on screen has become a frequent activity. However, the outcome of this method of reading has not been thoroughly investigated. Using a range of question types, comprehension was measured after reading from screen at both a normal and fast reading speed. In addition, by automatically recording how readers scrolled through each document, reading patterns were explored. A speed‐accuracy trade‐off was found and, in general, the recall of specific details was less accurate than responses to ‘higher order’ questions. However, questions that addressed the structure of the text were hardest. Analysis of the scrolling movements showed that the overall time spent pausing between movements was the best predictor of comprehension. At a normal reading speed, the most effective readers, in terms of higher comprehension scores, were those who spent more time between scrolling movements, which were fast and frequent.     

Supporting Programming and Learning-to-Program with an Integrated CAD and Scaffolding Workbench*

Programming is a complex cognitive task for students, because of the difficulty of finding the appropriate elements (the “decomposition” problem) and integrating them correctly into a whole (the “composition” problem). Programming is also hard to learn, because so much of the thinking behind a program is implicit and the process of programming is long and complicated. Our approach is to integrate a computer-aided design tool (CAD) with scaffolding to create a single, cohesive, and coherent workbench for the entire process. Our workbench is called the GPCeditor. We have evaluated its use by high-school students. Our results suggest that students program well in the GPCeditor, they learn good programming practices, and that the learning is occurring through use of the GPCeditor.     

OBE: Some Answers for the Uninitiated

In this article, leaders of the North Carolina Writing Project explore whether students of teachers who attended Writing Project summer institutes out-performed other teachers' students on state writing tests. The authors accordingly developed a test to compare the writing of those students with the writing of students of non-writing project teachers. The test, however, produced no significant difference in the writing of the two groups. Seventeen years later, the authors compared the longevity of writing project teachers with that of comparable non-writing project teachers to see if the institutes infused a spirit of professionalism and self-efficacy in participants that other teachers did not possess. This comparison affirmed the authors' beliefs: writing project teachers had greater staying power than comparable teachers.     

Teaching the language of mathematics at three levels of an English-medium primary school

This study, situated in a multilingual, English-medium educational context, draws on theory from mathematics and language education to capture teachers’ perspectives on the place of language in their mathematics pedagogy. The benchmark study explored this topic through surveying and interviewing teachers. Additionally, it sought to relate teachers’ views to their practice by focusing on observing three teachers’ mathematics lessons at primary one, three, and five. Findings are that mathematics teachers placed importance on teaching language, being specifically concerned with language as input and comprehension. They taught vocabulary and reading skills in supportive ways explicitly yet differently at the three grade levels. Particularly at the lower levels, teachers contextualised language in the concrete examples employed for mathematics teaching. At all three levels, prominence was given to teaching pupils how to read word problems as well as how to solve them. However, at primary three, a tension was observed between the two aims of teaching mathematical vocabulary and teaching the reading skills for word problems. This paper illustrates the tension and discusses its possible causes.     

Sustaining High-Quality Teaching and Evidence-Based Curricula: Follow-Up Assessment of Teachers in the REDI Project

Research Findings: Recent research has validated the power of evidence-based preschool interventions to improve teaching quality and promote child school readiness when implemented in the context of research trials. However, very rarely are follow-up assessments conducted with teachers in order to evaluate the maintenance of improved teaching quality or sustained use of evidence-based curriculum components after the intervention trial. In the current study, we collected follow-up assessments of teachers 1 year after their involvement in the REDI (REsearch-based, Developmentally Informed) research trial to evaluate the extent to which intervention teachers continued to implement the REDI curriculum components with high quality and to explore possible preintervention predictors of sustained implementation. In addition, we conducted classroom observations to determine whether general improvements in the teaching quality of intervention teachers (relative to control group teachers) were sustained. Results indicated sustained high-quality implementation of some curriculum components (the Promoting Alternative THinking Strategies curriculum) but decreased implementation of other components (the language/literacy components). Sustained intervention effects were evident on most aspects of general teaching quality targeted by the intervention. Practice or Policy: Implications for practice and policy are discussed.     

“The Coat Traps All Your Body Heat”: Heterogeneity as Fundamental to Learning

This article explores heterogeneity as fundamental to learning. Inspired by Bakhtin's notion of heteroglossia, a design team consisting of an experienced classroom teacher and 2 researchers investigated how a class of 3rd and 4th graders came to understand disciplinary points of view on heat, heat transfer, and the particulate nature of matter. Through a series of planned and unplanned encounters, official versions of the Second Law of Thermodynamics and the particulate view of matter were juxtaposed with varied domains of experience of heat transfer and phase change in water. We analyze the children's discourse to examine how they populated these phenomena with meaning and what they learned in the process. We conclude by describing key principles and a conundrum that emerged from this research.     

Examining the Beliefs and Practices of Four Effective Australian Primary Science Teachers

With trends across many countries still indicating the decline of student interest in school science and diminishing numbers of students studying science beyond the compulsory years, it seems that the field remains in crisis. To address these unfortunate trends, there needs to be a greater emphasis on science education research that highlights the good news stories. For example, what are science teachers actually doing in their classrooms to increase student interest and understanding in science? This article focuses on the science teaching beliefs and practices of four Western Australian primary school teachers. The teachers were nominated by a professional colleague as effective practitioners. The study involved gathering information from classroom observations and teacher interviews to provide background information to assist in developing understandings of these teachers and their science teaching. This article reports on the initial findings drawn from Deanne A, Kate B, Lisa C and Rebecca D. Their practices were organised into the following six categories: classroom environment; conceptual knowledge and procedural skills; teaching strategies and approaches; student-specific considerations; teacher-specific considerations; and context-specific considerations. In examining the components contributing to these categories, it was evident that the teachers’ beliefs, as well as the contextual factors inherent in each classroom environment, influenced how and why they teach science in the ways they do.
