The purpose of this article is to describe and demonstrate a three-step process of using differential distractor functioning (DDF) in a post hoc analysis to understand sources of differential item functioning (DIF) in multiple-choice testing. The process is demonstrated on two multiple-choice tests that used complex alternatives (e.g., "No…

The State Compensatory Education (SCE) program is designed to reduce dropout rates and increase academic performance of students identified as being at-risk of dropping out of school.

The purpose of this case study was to (a) examine the main and interaction effects of gender, race and class-type on mathematics achievement, mathematics attitudes and sources of mathematics self-efficacy, (b) investigate teacher-student interactions in the single-sex mathematics classes and (c) investigate perspectives about single-sex…

"Scaling" is the process of constructing a score scale that associates numbers or other ordered indicators with the performance of examinees. Scaling typically is conducted to aid users in interpreting test results. This module describes different types of raw scores and scale scores, illustrates how to incorporate various sources of…

In this article, the authors suggest that many of the problems struggling readers encounter while reading stem from distinct yet fundamental sources of difficulty related to the types of text read (print or online), the task or activity readers engage in, and the sociocultural context of reading.

This paper isolates and examines separately three distinct sources of error in essay scores: lack of agreement between raters; inconsistencies in performance within mode of discourse, and inconsistencies in performance between modes of discourse. Essay prompts in the Iowa Tests of Basic Skills (ITBS) Writing Supplement were designed to assess…

Enrollment in Seventh-day Adventist (SDA) schools is declining as is the number of schools and teachers. While there could be many reasons for this, one perception of SDA schools, held by parents, teachers, pastors, and school board members, is that students enrolled in schools with one, two, or three teachers do not achieve at the same rate as…

This study examined the reliability of three methods for detecting differential item functioning (DIF) (i.e., the Mantel-Haenszel method, the standardization method, and the logistic regression method) applied to achievement test data. In addition, the study examined the influences of different sources of error variance, including examinee,…

An experiment investigated the extent to which the results of out-of-level testing may be biased because the child given an out of level test may have had a significantly different curriculum than the children given in-level tests. Item analysis data suggested this was unlikely. (CTM)
