Just when you thought it was safe: synthetic phonics and syncretic literacy practices

Until just recently one might have been forgiven for considering the ‘Reading’ debate to have been amicably resolved, with, at the end of the twentieth century, a negotiated consensus reached comprised of all sides in the debate agreeing on a balanced approach to the teaching of initial reading. However, the recent intervention of the House of Commons Education and Skills Committee with its report, Teaching Children to Read, and its advocacy of synthetic phonics, has once again brought the teaching of reading in UK schools to public attention. This paper seeks to provide an interesting comparative example of a UK literacy context where synthetic phonics is employed regularly and systematically. Thousands of British schoolchildren attend mosque schools on a daily basis where they learn how to read the Classical Arabic of the Qur'an. They are taught how to decode the text accurately and fluently using synthetic phonics methods. This literacy practice is described and suggestions are made about what it might have to contribute to the discussion around the adoption of synthetic phonics in mainstream schools

The influence of reading unit size on the development of Stroop interference in early word decoding

The purpose of the experiments was to determine the automatic use of large or small word reading units in young readers in the absence of word decoding strategies. Picture-word Stroop interference was examined from four types of conflicting labels: (a) words containing both highly predictable grapheme–phoneme correspondence (GPC) units and highly consistent rime units (henceforth, Hi-GPC + Hi-Rime); (b) words with highly predictable GPC units and less consistent rime units (Hi-GPC + Lo-Rime); (c) words with low predictability GPC units and highly consistent rime units (Low GPC + High Rime); (d) nonwords that contained both highly predictable GPC and highly consistent rime units. Naming time for pictures containing these labels was compared against that for pictures with random letter strings or no labels. In Experiment 1, Stroop interference was examined in first, second, and third grade children to determine whether there was developmental change in the presence of rime or GPC interference. In Experiment 2, Stroop interference was examined as a function of relative reading skill in first grade children. In Experiment 3, Stroop interference in adults was compared to the use of rime or GPC pronunciation strategies for nonword reading. In all experiments, Stroop interference in picture naming was longer for pictures with highly predictable GPC unit labels than less predictable GPC unit labels. However, in Experiment 3, even though adults showed interference from predictable GPC units in the Stroop task, they always preferred rime pronunciation for ambiguous nonwords in the nonword reading task. It is argued that the current experiments provide evidence for a flexible units model. The results of this study were presented at the Cognitive Development Society meeting, November 2001, Virginia Beach, VA, and the American Educational Research Association meeting, April 2004, San Diego, California.

一种基于重排首次匹配算法的新颖并行Turbo译码器存储方案

In this paper we discuss a novel storage scheme for simultaneous memory access in parallel turbo decoder. The new scheme employs vertex coloring in graph theory. Compared to a similar method that also uses unnatural order in storage, our scheme requires 25 more memory blocks but allows a simpler configuration for variable sizes of code lengths that can be implemented on-chip. Experiment shows that for a moderate to high decoding throughput （40-100 Mbps）, the hardware cost is still affordable for 3GPP＇s （3rd generation partnership project） interleaver.
