This chapter provides an overview of sampling methods that are appropriate for conducting online surveys. The authors review some of the basic concepts relevant to online survey sampling, present some probability and nonprobability techniques for selecting a sample, and briefly discuss sample size determination and nonresponse bias. Although some…

There are few well-standardized measures of conversational breakdown in Autism Spectrum Disorders (ASD). The study's objective was to develop a scale for measuring pragmatic impairments in conversations of individuals with ASD. We analyzed 46 semi-structured conversations of children and adolescents with high-functioning ASD using a functional…

Students in an introductory psychology course took a quiz a week over each textbook chapter, followed by a cumulative final exam. Students missing a quiz in class could make up a quiz at any time during the semester, and answers to quiz items were available to students prior to the cumulative final exam. The cumulative final exam consisted of half…

Tests often are used to assist in assessing common childhood disabilities and disorders (e.g., mental retardation). Learning disabilities and difficulties (LD) constitute the plurality, even the majority, of school-related disorders in many countries. However, tests and other assessment methods to assess LD are not available universally and, among…

Developing scoring rubrics to evaluate student work was studied, concentrating on the use of intermediate points in rating scales. How scales that allow for intermediate points between defined categories should be constructed and used was explored. In the recent National Assessment of Educational Progress (NAEP) visual arts field test, researchers…

The Johnson O'Connor Research Foundation, which produces vocabulary instructional materials for test takers, is in the process of determining the difficulty values of nontechnical words in the English language. To this end, the Foundation writes test items for vocabulary words and tests them in schools. The items are then calibrated using the…

When one considers the importance and social significance of licensing and certification examinations, it is amazing that the enterprise operates with virtually no societal oversight. The "Standards for Educational and Psychological Testing" and the "Code of Fair Testing Practices in Education" of the American Psychological…

In this study, the ability of test development staff to predict the difficulty of analogy items was explored. The nature of the item attributes that contributed to test writers' predictions of difficulty as well as actual item difficulty was also investigated. The two expert test writers studied were quite good at predicting item difficulty. Item…

The National Assessment of Educational Progress (NAEP) is a congressionally mandated project of the U.S. Department of Education's National Center for Education Statistics. It assesses what students in the United States should know and be able to do in geography, reading, writing, mathematics, science, U.S. history, the arts, civics, and other…

This study was patterned after a previous study by Skaggs and Lissitz (1992) in which inconsistency of differential item functioning (DIF) was reported across test administrations. They suggested multidimensionality of test data as one possible reason for inconsistency. Therefore, in this study, DIF indices which were developed recently with a…

The Myers-Briggs Type Indicator (MBTI) is introduced. Some historical background and an overview of preference and types are given. Applications of the MBTI are discussed, focusing on educational issues concerning the study of learning styles. Learning styles are defined according to D. H. Kalsbeek, G. Lawrence, and others. Each dichotomous…

Two studies among U.S. college students (n=88 and n=329) examined the relationships between the order in which responses are offered on a questionnaire and the ranked importance of those responses. Study 1 included 36 males and 52 females, and Study 2 included 127 males and 202 females. Both studies found that approximately one-third (32 percent…

Randomization tests have been suggested as a method for analyzing the data from single-case designs. This paper explores three concerns which have arisen: the nonresponsive nature of randomization tests, the appropriateness of specific test statistics and the power of these tests. An example is given to illustrate how partial control can be given…

Many school districts face the problem of evaluating new programs to train students in ethics and moral decision making. Using conventional personality tests in program evaluation may be helpful, but probably will not provide measures for the attitudes that are targeted by the intervention. The method of equal- appearing intervals developed by L.…

An integer programming approach to item pool design is presented that can be used to calculate an optimal blueprint for an item pool to support an existing testing program. The results are optimal in the sense that they minimize the efforts involved in actually producing the items as revealed by current item writing patterns. Also, an adaptation…
