Introduction • It is important for beginning readers to develop reading fluency. • Fluency means reading faster, smoother and more expressively without errors.
Introduction • Reading fluency: Basic Skill for School-aged Children. • Generally, reading fluency is important in primary and intermediate grades (Chall, 1983). • Students with LD show problems in reading fluency, which hinder reading comprehension.
The significance of Reading Fluency in primary grade levels. 1 Growth Rate for Reading between students with/without learning disabilities. 2 Correlates for Reading Fluency Development. 3 Purpose
Research Questions Is the reading growth model linear or non-linear? Reading Fluency in primary grade level (Grade 1 – 4) Which variables affect reading growth, [gender, grade, and student status(reg./sped.)]
Stage of Reading Development(Chall, 1983) College, Age 18 and Above Stage 5. Construction and Reconstruction of meaning High School, Ages 14-18 Stage 4. Multiple Viewpoints Grades 4-8, Ages 8-14 Stage 3. Read to Learn Grades 2-3, Ages 7-8 Stage 2. Fluency Grades 1-2, Ages 6-7 Stage 1. Initial Reading, or Decoding Stage Birth to Age 5 Stage 0.

Curriculum Based Measurement Reading Fluency Curriculum-based measurement (CBM) is a tool for measuring student competency and progress in the basic skill areas Mathematics Spelling Written Expression Especially Basic Skill
BASA( Korean CBM) Phase 1 Phase 2 Phase 3 • How many words a student correctly reads in one minute • the mid-point score is reported. • three reading probes are given BASA - Basic Academic Skills Assessment : Reading
Method BASA original norm group: 3 time-point measure Grade 1 : 27, 2 : 31, 3 : 44, 4 : 6 Participants Reading Scores(repeated measures) gender, grade, status(reg. Vs. sped.). Variables Hierarchical Linear Model Analytical Methods

Result(2) • Average reading scores increased by 13.3 every year(p<.05). • Female Students read more 0.6 then male Students in Grade 2(Non-Sig.). • The initial score (starting point) of male students is lower than that of female, • but growth rate for male students is higher(Non-Sig). • Regular class students read more fluently than Special students (p<.05). • The average reading growth rate was 2.0 score per week, but decreased • by 0.7 score as the grade level increased • Growth Rate is different by grade level, • not by gender and status (regular-special education).
Implications • Reading growth model is linear. • Under the general circumstances, the initial gap between children with • and without Learning Disabilities(LD) does not decrease in the primary • grade level. Thus, early & intensive reading intervention is in order for the students with LD.
