Researchers design diagnostic assessments to measure students' knowledge structures and processing skills to provide information about their cognitive attribute. The purpose of this study is to determine the instrument's validity and score reliability, as well as to investigate the use of classical test theory to identify item characteristics. The…

Reliability is usually estimated for a total score, but it can also be estimated for item scores. Item-score reliability can be useful to assess the repeatability of an individual item score in a group. Three methods to estimate item-score reliability are discussed, known as method MS, method [lambda][subscript 6], and method CA. The item-score…

This article describes and reviews the "Test of Early Communication and Emerging Language" (TECEL; Huer & Miller, 2011). The test was constructed to assess infants' and toddlers' earliest communication and language abilities. The TECEL is a revision of the Nonspeech Test for Receptive/ Expressive Language (NST; Huer, 1983, 1988). The…

Background: A feasible and reliable instrument to measure strength in persons with severe intellectual and visual disabilities (SIVD) is lacking. The aim of our study was to determine feasibility, learning period and reliability of three strength tests. Methods: Twenty-nine participants with SIVD performed the Minimum Sit-to-Stand Height test…

This paper proposes and validates a short and simple Expectancy-Value-Cost scale, called EVC Light. The scale measures the motivation of students in computing courses, allowing the easy and weekly application across a course. One of the factors related directly to the high rate of failure and dropout in computing courses is student motivation.…

With the study reported on here we aimed to explore the relationship between situational determinants of teachers' perceptions of organisational politics in some public high schools in the KwaZulu-Natal province. We adopted a crossregional survey design and convenience sampling to study teachers (n = 301) at public high schools in all 10 districts…

Purpose: Measuring internal response of online learning is seen as fundamental to absorptive capacity which stimulates knowledge assimilation. However, the evaluation of practice and research of validated instruments that could effectively measure online learning response behavior is limited. Thus, in this study, a new instrument was designed…

The main goal of the current study is to develop a reliable instrument to measure programming anxiety in university students. A pool of 33 items based on extensive literature review and experts' opinions were created by researchers. The draft scale comprised three factors applied to 392 university students from two different universities in Turkey…

This study addressed the cross-cultural validation of the Chinese Motivation for Reading Questionnaire (CMRQ) in a sample of 522 seventh to ninth graders from two public schools in eastern China. Confirmatory factor analyses, item-total correlation analyses, and reliability analyses were conducted to assess the psychometric quality of the CMRQ.…

This research was aimed to develop the Teacher Report Form of Anxiety in Pre-School children. A descriptive research was conducted with two study groups. The scale is based on teachers' assessment for preschoolers aged 3-6. During the development process of the form, the theoretical structure was examined and expert opinion was take for the…

Assessment of individuals on the autism spectrum often includes a measure of nonverbal IQ. One such measure is the Raven's Standard Progressive Matrices (RSPM). For large research studies with participants distributed nationally it is desirable for assessments to be available online. Because time is a premium, it is ideal that the measure produces…

Background: Self-selected exercise intensity (SSEI) promotes higher affect (pleasure) during exercise, but its reliability is still unclear. Purpose: to evaluate the test-retest reliability and the minimum detectable change of the perceptive and physiological responses in two sessions of SSEI on treadmill in elderly women. Method: Twenty elderly…

Little is known about the across time stability of autistic traits during the transition period from preschool to school age in the general population. The current study compared autistic traits assessed by a mother-reported quantitative measure, the Social Responsiveness Scale, at age 5 and 8 years and examined the intraclass correlation…

Purpose: The purpose of the study is to investigate biomechanical and physiological responses to soccer-specific exercise incorporating an extra-time period (ET) and assess the test-retest reliability of these responses. Methods: Twelve soccer players performed 120 min of soccer-specific exercise. Tri-axial (PL[subscript Total]) and uni-axial…

The purpose of this study was to design and validate a complex gait test (CGT) in preschool children and to examine the relationship between CGT performance and age, sex, and cognitive functioning. A total of 1,040 preschool children, aged 3 to 6 years, participated in this study. In all children, standardized dynamic balance test, and several…
