Why Students are Struggling to Learn: Analyzing DAS-II Test Results Within a CHC Framework (Session 2) Gloria Maccow, Ph.D. Assessment Training Consultant

Agenda Use case study data to illustrate the interpretive process to 1)

determine if the child able to perform complex mental processing;

2)

identify intra-individual cognitive strengths and weaknesses;

3)

determine if identified cognitive strengths and weaknesses explain identified weaknesses in achievement.

Introducing Winston . . . •

Winston is in second grade at Salem Elementary.



His language appears appropriate for his age. He uses complete sentences to describe his experiences and chooses words that convey his ideas.



During math activities, he frequently raises his hand to answer the teacher’s questions. His performance in math is at grade level.

Introducing Winston . . . •

When working with small groups of classmates on math, he assumes a leadership role.



However, Winston does not display the same enthusiasm for reading.



His reading skills are below grade level.

Deficit in Word Reading (Reading CBM)



School’s target - 57 words read correctly per minute.



Class average - 58 words read correctly per minute.



Winston - 30 words read correctly per minute.



He read 10 words incorrectly which resulted in an accuracy rate of 75%.



His performance was the lowest in the class and well below average.

Monitor Progress •

Oral reading fluency improved from 30 words correct per minute to 32 words correct per minute.



Performance improved at a rate of 0.5 words correct per week.



Performance of his four classmates improved at a rate of 0.8 - 1.5 words correct per week.

Weakness in Decoding Pronouncing unknown words requires: − Encoding written words into temporary memory and then segmenting (in working memory) units of the written word−wholes, single letters, letter clusters. − Phonological awareness of the syllables in multi-syllabic spoken words. − Phonological awareness of the phonemes in spoken words. 15 | Copyright © 2013.

Alphabetic Principle •

Teach strategies for changing printed words into spoken words.



For example, use Talking Letters to teach spelling-sound correspondences.



The child can use these correspondences to help sound out words in the story you will read later.



Focus on naming the letter(s), the picture, and then the sound.

37 | Copyright © 2013. All rights reserved.

Subword Level Use Talking Letters Student Desk Guide to teach letter(s) – phoneme correspondences in alphabetic principle (spelling to phoneme direction).

Word Level Use teacher-constructed word card deck to teach Winston to apply the alphabetic principle to monosyllabic word reading.
