Course: Communication Research Methods. Objectives: This activity provides students with an experiential introduction to measurement theory and the methods for assessing measurement reliability. First, multiple measurements of a person's height are interpreted according to classical test theory. Second, the measurement of human height is used as…

The current study sought out to advance the Social Self-Efficacy and Social Outcome Expectations scale using multiple approaches to scale development. Data from 583 undergraduate students were used in two scale development approaches: Classic Test Theory (CTT) and Item Response Theory (IRT). Confirmatory factor analysis suggested a 2-factor…

The main purpose of this study is to develop a perceived stress scale based on Classical Test Theory (CTT) and Graded Response Model (GRM); to compare the parameters of the items in the scale that are tried to be developed according to both models, and to determine under which theory the measurement tool produces more reliable and valid results…

The current study shows the applications of both classical test theory (CTT) and item response theory (IRT) to the psychology data. The study discusses item level analyses of General Mattering Scale produced by the two theories as well as strengths and weaknesses of both measurement approaches. The survey consisted of a total of five Likert-type…

The current gap between traditional team research and research focusing on non-strict teams or groups such as teacher teams hampers boundary-crossing investigations of and theorising on teamwork and collaboration. The main aim of this study includes bridging this gap by proposing a continuum-based team concept, describing the distinction between…

The Early Fractions Test is a paper-pencil test designed to measure mathematics achievement of third- and fourth-grade students in the domain of fractions. The purpose, or intended use, of the Early Fractions Test is to serve as a student pretest covariate and a test of baseline equivalence in the larger study. In this report, we discuss our…

Concept inventories (CIs)--typically multiple-choice instruments that focus on a single or small subset of closely related topics--have been used in science education for more than a decade. This paper describes the development and validation of a new CI for astronomy, the "Star Properties Concept Inventory" (SPCI). Questions cover the areas of…

Research on the graphical facilitation of probabilistic reasoning has been characterised by the effort expended to identify valid assessment tools. The authors developed an assessment instrument to compare reasoning performances when problems were presented in verbal-numerical and graphical-pictorial formats. A sample of undergraduate psychology…

Language assessment courses (LACs) are taught by professionals who have majored in the area of language testing (language testers or LTs), but also by others who come from different language-related majors (non-language testers, non-LTs). Different language assessment courses may be developed, depending on who teaches the course and the…

In much of the world, the issue of accountability and measurement of educational outcomes is highly controversial. Exit testing is part of the movement to ascertain what students have learned and hold institutions and teachers to account. However, compared to the large number of teacher washback studies, learner washback research is lacking…

Results obtained when a procedure for assessing the questions on uniersity mathematics examinations to see what skills were needed for their solution are given for a sample of 1400 questions set during 1976 in 10 British universities. The method is a way of focusing rational argument. (MNS)

Reading comprehension involves a number of distinctly different intellectual skills that can be assessed if the proper techniques are employed. As part of a reading assessment system, two measures of literal comprehension were developed: the Literal Comprehension Details Test (LCDT) and the Paraphrase Reading Test (PRT). Both the LCDT and the PRT…

This study examined four measures of creativity as predictors of mathematics and science performance in a program for talented high school students (N=29). Correlational analyses indicated that the How Do You Think Test (HDYT) and ratings on the Teachers' Evaluation of Students' Creativity (TESC) were predictive of the students' performance in the…

The relationship between classical discrimination indices (CDI) and criterion-referenced discrimination indices (CRDI) and the appropriateness of each for use on criterion-referenced tests are investigated. A CRDI is proposed that attempts to separate those who master material from those who do not master material. A 26 item multiple-choice…

A content-oriented analysis of written solutions to test items in Israeli high school graduation examinations in mathematics yielded six error categories: misused data; misinterpreted language; logically invalid inference; distorted theorem or definition; unverified solution; and technical error.
