Grapheme: the individual letter or sequence of written symbols (e.g., a, b, c,) and the multi-letter units (e.g., ch, sh, th) that are used to represent a single phoneme. Irregular Word: A word that cannot be decoded because either the sounds of the lett

7、ntification strategy,Importance of Word Reading in Text,A primary goal of beginning reading instruction is to prepare students to read text fluently so that they are able to construct meaning as the read.,Irregular Words,Do Not introduce irregular words until students can reliably decode words at a
8、rate of one letter-sound per second. Initially, introduce one word every several lessons, then one each second or third lesson Irregular words require systematic review. New words should appear in word-list exercises for several days, then appear in either or both passages and word-list exercises. .
9、,Advanced Word Analysis,Knowledge of advanced word analysis skills is essential if students are to progress in their knowledge of the alphabetic writing system and gain the ability to read fluently and broadly.,Advanced Word Analysis,Letter Combination: A group of consecutive letters that represents
10、 a particular sound(s) in the majority of words in which it appears. VCe Pattern Word: Word pattern in which a single vowel is followed by a consonant, which, in turn, is followed by a final e (e.g., lake, stripe, and smile).,Letter-Sound Correspondence,Example: Teacher points to letter m on the boa

13、6-8 other letter sounds When students can identify 4-6 letter-sound correspondences in 2 seconds each, include these letters in single-syllable, CVC, decodable words Review Cumulatively and JudiciouslyUse a distributed review cycle to build retention: NKNKKNNKKKKNN = new sound; K = known soundExampl

15、ay it fast. “ (map) Conspicuous Strategies: Students orally produce each sound in a word and sustain that sound as they progress to the next. Students must be taught to put those sounds together to make a whole word Students sound out the letter-sound correspondences “in their head” or silently and
16、then produce the whole word.,Mediated Scaffolding: For students to learn and apply knowledge of letter-sound correspondences and use that knowledge to reliably decode words, words must be carefully selected for both the letters in the words and the complexity of the words. Letters in words for initi

18、on sounds to longer words (4-5 phoneme words) in which letters represent their most common sound,Not contain consonant blends (e.g., /st/, /tr/, /pl/) until students are proficient with CVC configurations Begin with continuous sounds in early exercises to facilitate blending. Stop sounds may be used
19、 in final positions of words. Represent vocabulary and concepts in which students are familiar. Judicious Review Prior to reading the words, review the letter-sound correspondences that have been recently introduced or are problematic for learners As you progress to each new phase of word reading (s

21、eable length (6-8 words per list),Reading Connected Text Accurately and Fluently,Instructional Design Considerations A primary goal of beginning reading instruction is to prepare learners to read passages in order to communicate that print has purpose and meaning Once students can accurately decode
22、CVC and VC word types, these words should be introduced in short, highly controlled passages Do Not assume that learners will automatically transfer from reading words correctly in lists to reading words in passages.,Conspicuous Strategies 2 components First component: teacher provides direct wordin
23、g for students to “figure out the word, say the sounds in the word to yourself.” This component generally lasts 1-2 weeks. Second component of transitioning to passage reading involves a modified prompt where teachers give a direction at the beginning of the passage.For example, the teacher says, “F
24、igure of the first word” and then asks students to read the word. Note the prompting to say the sounds is eliminated. A final technique is to increase the pace of word reading. In initial passage reading exercises, allow 3 seconds of “think time” per word. As students become proficient (I.e., readin
25、g the passage with no error), reduce the think time to 2 seconds and later to 1.5 seconds.,Mediated Scaffolding Ensure students can read the words in lists at a rate of one word per 3 seconds Include only words students can decode in passages Include repeated opportunities to read passages to develo
