Official communications and media news in Greece about the COVID-19 pandemic very often involve a multitude of numerical concepts and mathematical relationships, which are presented in different forms and in various contexts. This paper reports selected findings of a survey among adults, which had two aims. First, to investigate their subjective…

Today, most medical research depends on statistics, and interpreting these is crucial as the world tries to improve health outcomes. Medical students are at the front line in this effort but many have negative attitudes toward statistics. To assess this and offer recommendations, this study evaluates the attitudes of medical students in Riyadh,…

The aim of this research was comparing the performance of primary school Chilean children when reading different types of graphs included in the primary school curriculum in this country (pictogram, line graph, pie chart and dot plot). A sample of 745 6th and 7th Grade students were given a questionnaire including four tasks in each of which they…

The expertise reversal effect occurs when learner's expertise moderates design principles derived from cognitive load theory. Although this effect is supported by numerous empirical studies, indicating an overall large effect size, the effect was never tested by inducing expertise experimentally and using instructional explanations in a…

It is a widely held belief that an anchor test used in equating should be a miniature version (or "minitest") of the tests to be equated; that is, the anchor test should be proportionally representative of the two tests in content and statistical characteristics. This paper examines the scientific foundation of this belief, especially…

A study was undertaken to develop guidelines for the interpretation of the parameters of three multidimensional item response theory models and to determine the relationship between the parameters and traditional concepts of item difficulty and discrimination. The three models considered were multidimensional extensions of the one-, two-, and…

The Test for Inquiry Social Studies (TISS) is a 40-item multiple-choice instrument designed to measure the application of either inquiry social studies or higher-level cognitive thinking skills in fifth and sixth graders. The test can generally be completed in 40 to 50 minutes. This administrator's guide contains information on the reliability,…

Empirical evidence is presented related to the effects of using a stratified sampling of items in multiple matrix sampling on the accuracy of estimates of the population mean. Data were obtained from a sample of 600 high school students for a 36-item mathematics test and a 40-item vocabulary test, both subtests of the Iowa Tests of Educational…

TRAINING TASKS WERE PRESENTED UNDER LABORATORY CONDITIONS TO NEWLY INDUCTED ARMY BASIC TRAINEES GROUPED BY ARMED FORCES QUALIFICATION TEST (AFQT) SCORES. THE HIGH GROUP (N=52) RANGED IN SCORE FROM 90 TO 99, THE MIDDLE GROUP (N=30) FROM 45 TO 55, AND THE LOW GROUP (N=61) FROM 10 TO 21. TASKS WERE VARIED IN COMPLEXITY INCLUDING SIMPLE AND CHOICE S-R…

The work presented in this paper defined conceptually the concepts of multidimensional discrimination and information, derived mathematical expressions for the concepts for a particular multidimensional item response theory (IRT) model, and applied the concepts to actual test data. Multidimensional discrimination was defined as a function of the…

CHANGE IN INFORMATION PROCESSING AND CHANNEL CAPACITY WITH INCREASE IN AGE WAS STUDIED, AND POSSIBLE ALTERING OF THIS RELATIONSHIP WITH A CHANGE IN COMPLEXITY AND DIMENSIONALITY OF THE STIMULUS PRESENTED. VISUAL STIMULI WERE PROJECTED ON A SCREEN TO FOUR GROUPS COMPOSED OF 74 COLLEGE GRADUATES, RANGING IN AGE FROM 23 TO 68 YEARS, IN A SIMULATED…

The "A" testing program of the Beginning Teacher Evaluation Study, Phase III-B, is summarized. A sample of 150 second grade and 134 fifth grade students completed the reading and mathematics achievement battery, as well as affective scales regarding reading, mathematics, and school. The administration procedures, test results, and psychometric…

The "B" testing program of the Beginning Teacher Evaluation Study, Phase III-B, is summarized. A sample of 146 second grade and 128 fifth grade students completed the reading and mathematics achievement battery, as well as affective scales pertaining to reading, mathematics, and school. The administration procedures, test results, and psychometric…

The "C" testing program, which followed the "A" and "B" tests of the Beginning Teacher Evaluation Study, is summarized. A sample of 139 second grade and 123 fifth grade students completed the reading and mathematics achievement battery, as well as affective scales regarding reading, mathematics, and school. The administration procedures, test…

This document accompanies the Conceptual Learning and Development Assessment Series III: Tree, a test constructed to chart the conceptual development of individuals. As a technical manual, it contains information on the rationale, development, standardization, and reliability of the test, as well as essential information and statistical data for…
