The notion of validity in the social sciences is evolving and is influenced by philosophy of science, critiques of objectivity, and epistemological debates. Methodology for validation of the knowledge claims is diverse across different philosophies of science. In other words, definition and the way to establish of validity have evolved as…

The purpose of this study was to develop a step test with a personalized step rate and step height to predict cardiorespiratory fitness in 80 college-aged males and females using the self-reported perceived functional ability scale and data collected during the step test. Multiple linear regression analysis yielded a model (R = 0.90, SEE = 3.43…

To support students' academic, behavioral, and social needs, many schools have adopted multitiered models of prevention. Because Tier 3 interventions are costly in terms of time and resources, schools must find efficient and effective Tier 2 interventions prior to providing such intense supports. In this article, we review the literature base on…

Two Bayesian observer models were recently proposed to account for data from the Eriksen flanker task, in which flanking items interfere with processing of a central target. One model assumes that interference stems from a perceptual bias to process nearby items as if they are compatible, and the other assumes that the interference is due to…

Research indicates that many elementary students do not comprehend that the equal sign is an indication that an equality relation exists between two structures. Instead, they perceive the equal sign as an indication that a particular procedure is to be performed. As students mature, and as their exposure to the equal sign and equality relations in…

Objective: There is increasing emphasis on dimensional conceptualizations of psychopathology, but empirical evidence of their utility is just emerging. In particular, although a range of multidimensional models have been proposed, the relative fit of competing models has rarely been tested. Furthermore, developmental considerations have received…

We propose three latent scales within the framework of nonparametric item response theory for polytomously scored items. Latent scales are models that imply an invariant item ordering, meaning that the order of the items is the same for each measurement value on the latent scale. This ordering property may be important in, for example,…

Web-based problem-solving, a compound ability of critical thinking, creative thinking, reasoning thinking and information-searching abilities, has been recognised as an important competence for elementary school students. Some researchers have reported the possible correlations between problem-solving competence and information searching ability;…

Although there is a widespread interest in testing in geography, very few empirical studies exist of internationally validated testing models. Arguably the best international geography test in secondary education is found in the International Geography Olympiad, and this test is the focus of this paper. Apart from a written response test and…

This study investigates how a natural experiment occurring in the teaching of principles of microeconomics allows a test of the Dunn and Dunn learning styles model (Dunn & Griggs, 2000). The material for the first exam, based on essential definitions and theoretical foundations, was taught in a conventional, inductive style, more compatible with…

The rationale underlying tests of social intelligence and some of the problems inherent in those tests are discussed. To measure social intelligence, paper and pencil tests were developed which were "situation free." These tests employed "stereotypic behavior of individual others." The stimuli used in the behavioral tests were…

Raven's Coloured Progressive Matrices and a battery of ability tests were administered to a sample of 104 male fourth graders for purposes of investigating the relationships between 2 previously identified subscales of the Raven and the ability tests. Results indicated use of a spatial strategy and to a lesser extent, use of reasoning, indicating…

Student test-taking motivation in low-stakes assessment testing is examined in terms of both its relationship to test performance and the implications of low student effort for test validity. A theoretical model of test-taking motivation is presented, with a synthesis of previous research indicating that low student motivation is associated with a…

The predictive validity of the Comparative Guidance and Placement Program (CGP) tests for two diverse curricular groups was examined. Three methods for developing predictive equations were compared. The CGP was administered to 417 Liberal Studies and 316 Business Technical students at a New England community college. Principal component analyses…
