Decoding Strategies (decoding + strategy)
Selected AbstractsAdvanced Phonics: Teaching Strategies for Poor Readers at Key Stage 2ENGLISH IN EDUCATION, Issue 3 2000Susan Jennings Abstract Poor readers at Key Stage 2 need ongoing support for their reading development. They are frequently weak in the metacognitive skills that enable good readers to make their own progress and they require a repetition of much phonics material from Key Stage 1. Beyond that, they have a need for the further complexities of English to be taught to them as phonics, not as spelling strategies/investigations. Additionally, they have difficulty in tackling polysyllabic words and must be taught appropriate decoding strategies. There is a dearth of teaching materials in this area and little research evidence as to how such material might best be taught. This paper charts the development of a phonics booster programme for poor readers in Year 5. [source] Construction, analysis and performance of generalised woven codesEUROPEAN TRANSACTIONS ON TELECOMMUNICATIONS, Issue 2 2004Martin Bossert Generalised woven codes (WC) are constructed by combining the woven code structure with the idea of generalised concatenated codes, also known as multi-level codes. The required nested inner convolutional code is analysed. The encoder structure of this new class of codes is described and fundamental code parameters are derived. It is shown that generalised WC have a free distance which is superior to that of comparable WC. Several iterative and non-iterative decoding strategies are discussed. It is shown that the decoding complexity of the nested inner code is not larger than the decoding complexity of its mother code. Finally, bit error rates obtained from simulations are discussed and compared with other code structures like WC.

The proposed AODFD does not require an infinitely long whiten filter in its feed-forward stage, however, which is necessary in the traditional ADDFD detector reported in the literature. The updating algorithm of the AODFD detector is also much simplified if compared with that of ADDFD that requires computational intensive z -transformed matrix inversion and spectral factorization. Results show that, despite its low complexity, the AODFD performs very well under multiple access interference. The proposed two new decoding strategies can also be chosen to cater for different operating scenarios. Copyright © 2001 John Wiley & Sons, Ltd. [source] Exact Repetition as Input Enhancement in Second Language AcquisitionLANGUAGE LEARNING, Issue 3 2003Eva Dam Jensen This study reports on two experiments on input enhancement used to support learners' selection of focus of attention in second language listening material. Eighty-four upper intermediate learners of Spanish took part. The input consisted of video recordings of quasi-spontaneous dialogues between native speakers, in tests and treatment. Exact repetition and speech rate reduction were examined for their effect on comprehension, acquisition of decoding strategies, and linguistic features. Each of three groups listened to each utterance of the dialogue three times, in different speed combinations: fast-slow-fast, fast-slow-slow, fast-fast-fast, respectively. A fourth group served as a baseline and received no treatment. Comparisons of pretest and posttest scores showed significant effects for all three parameters. No difference with regard to effect could be established between treatment conditions. [source] | ||||||||||
