Research suggests that restricted and repetitive behaviors (RRBs) can be subdivided into Repetitive Sensory Motor (RSM) and Insistence on Sameness (IS) behaviors. However, because the majority of previous studies have used the Autism Diagnostic Interview-Revised (ADI-R), it is not clear whether these subcategories reflect the actual organization…

The present study investigated a direct assessment of behavioral self-regulation (the Head-Toes-Knees-Shoulders; HTKS) and its contribution to early academic achievement among young children in Germany and Iceland. The authors examined the psychometric properties and construct validity of the HTKS, investigated gender differences in young…

This quantitative study examined the structure, validity, and reliability of the "Three-Dimensional Worldview Survey-Form C" ("3DWS-Form C") for potential use in postsecondary Christian institutions. This instrument delineates from other worldview instruments in that it purports to measure three components of a person's…

The aim of this research is to examine the validity and reliability of the Turkish version of the Employment Hope Scale (EHS; Hong et al. 2012). The sample of this study consisted of 398 (235 female and 163 male) teachers. The results of confirmatory factor analysis demonstrated that the six items loaded on one factors and the one-dimensional…

Direct observation is often considered the "gold standard" for assessing the function, frequency, and intensity of problem behavior. Currently, the literature investigating the construct validity of direct observation conducted in the clinic setting reveals conflicting results. Previous studies on the construct validity of clinic-based…

This study investigates the construct validity, composite reliability and concurrent validity of the "Inventory of attitudes towards seeking mental health services" (IASMHS). A large sample of Irish police officers (N = 331) participated in the study. Confirmatory factor analysis supported the three-factor structure of the scale, while…

Background: Misconceptions are major obstacles to learning physics, and the concepts of heat and temperature are some of the common misconceptions that are encountered in daily life. Therefore, it is important to develop valid and reliable tools to determine students' misconceptions about basic thermodynamics concepts. Three-tier tests are…

This article defines the concept of Domain Theory, or, when educational measurement is the goal, one might call it a "Learning Theory of Progressive Attainments in X Domain". The concept of Domain Theory is first shown to be rooted in validity theory, then the concept of domain theory is expanded to amplify its necessary but long neglected…

The current study is a quantitative research that aims to throw light on the place of students' views on contextual vocabulary teaching in conformity with Constructivism (CVTC) in the field of foreign language teaching. Hence, the study investigates whether any significant correlation exists between the fourth year university students' attitudes…

This study compares learners' writing in an impromptu, timed writing (ITW) exam and in a process-based, timed writing (PBTW) exam to investigate the differences between these two types of assessments. A secondary objective of this study is to examine the test takers' attitudes towards the two exams. Forty participants taking ESL writing classes…

Researchers have been keen to develop instruments for the assessment of teachers' self-perceived technological pedagogical content knowledge (TPACK); however, few studies have been conducted to validate such assessment tools through students' perspectives in the context of English as a foreign language (EFL). The purpose of this study was thus to…

This article presents research to delineate the construct of instructor strategic ambiguity (ISA) and develop a measure. The first study analyzed instructor uses of ambiguity, identified 18 strategies, and classified them into four categories. The second study developed an Instructor Strategic Ambiguity Measure (ISAM) for the college classroom.…

This study addresses whether reading involves a process termed semantic and phonological ability to adjust recoding (SPAAR). It was hypothesized that SPAAR helps readers link inaccurate pronunciations to lexical entries (e.g., "spynitch" to "spinach"). Psychometric properties of the Mispronunciation Correction Task (MCT), a…

Citizen science programs provide opportunities for students to help professional scientists while fostering science achievement and motivation. Instruments which measure the effects of this type of programs on student motivational beliefs are limited. The purpose of this study was to describe the process of examining the reliability and validity…

The aim of the study is to investigate how university students perceive academicians' democratic values, and whether their perceptions on it differ significantly according to certain variables. Designed as a descriptive quantitative research, this study employs of 248 students studying at the Faculty of Education and Faculty of Economics and…
