Equating WCPM scores across passages of MAP Reading Fluency
March 2020
By: Jing Chen, Mary Ann Simpson

Description
NWEA equated words-correct-per-minute (WCPM) scores from oral reading passages included in the NWEA MAP Reading Fluency assessment. Equipercentile equating with loglinear presmoothing was applied to convert raw WCPM scores from a non-reference passage to those from a reference passage. The goals of this study were to (1) develop a method to choose a reference passage and passage pairs for equating WCPM scores from a large number of passages and (2) determine if equated WCPM scores provide a more accurate indication of studentsā oral reading fluency ability compared to the raw WCPM scores from passages that vary in difficulty.

Achievement and Growth Norms for Course-Specific MAP Growth Tests
This report documents the procedure used to produce the achievement and growth user norms for a series of the course-specific MAP® Growth⢠subject tests, including Algebra 1, Geometry, Algebra 2, Integrated Math I, Integrated Math II, Integrated Math III, and Biology/Life Science. Among these tests, Integrated Math I, Integrated Math II, Integrated Math III, and Biology/Life Science were the first time to have their norms available. The remaining tests, i.e., Algebra 1, Geometry, and Algebra 2, had their norms updated including receiving more between-term growth norms by using more recent test events. Procedure for norm sample selection and a model-based approach using the multivariate true score model (Thum & He, 2019) that factors out known imprecision of scores to generate the norms are also provided in detail, along with the snapshots of the achievement and growth norms for each test.

Longitudinal models of reading and mathematics achievement in deaf and hard of hearing students
New research using longitudinal data provides evidence that deaf and hard of hearing (DHH) students continue to build skills in math and reading throughout grades 2 to 8, challenging assumptions that DHH students’ skills plataeu in elementary grades.

This study evaluates the effects of asking items throughout the passage (i.e., embedding items) to achieve a more precise measure of reading comprehension by removing barriers for students to demonstrate their understanding. Results showed a significant impact of embedding comprehension items within reading passages on the measurement of student achievement in comparison to answering items at the end of the passage.
