The idea of sources other than the test-takers' knowledge leading to different results on high-stakes tests was the motif based on which the present investigation was initiated on the probable sources of unreliability of a test. For this purpose, the researchers went through a thorough literature review with the aim to identify the issues to be…

The aim of this study was to develop and validate a psychometrically-sound instrument to assess students' perceptions about class cohesion. Two studies were conducted. In Study 1, four steps were established: (1) development of the Class Cohesion Questionnaire (CCQ); (2) item selection; (3) item compression; and (4) exploration of psychometric…

Awareness of informational text structures is related to reading comprehension and varies according to characteristics of readers and texts. The purpose of this study was to develop and refine a measure of text structure awareness, the Text Structure Identification Test (TSIT), by investigating its internal consistency reliability and construct…

Diagnostic tests have been developed previously to measure algebraic thinking skills; however, the tests do not specifically address algebraic problem-solving. Thus, an Algebraic Thinking Test (ATT) Instrument was developed to measure algebraic thinking skills in problem-solving involving linear equations. ATT comprises nine open-ended questions…

This study focused on the development and validation of the Sense of Online Community Scale (SOCS), which includes 28 Likert-type scale items across six subscales: (1) program community; (2) program academic activities; (3) program social activities; (4) institutional academic activities; (5) institutional social activities; and (6) affiliation.…

We assess the psychometric properties of the test and also correlate the…

There is a growing recognition of the need for interventions to improve the healthcare of autistic adults. However, there is a dearth of validated measures to evaluate such interventions. Our objectives were to use a community-based participatory research approach to create an accessible set of patient- and proxy-reported instruments to measure…

A subtest of the LLAMA test battery (LLAMA_D) has been proposed as a potential test of implicit learning aptitude. To improve its construct validity, in the present study, the original LLAMA_D (a) instructions for incidental learning were modified, and (b) confidence ratings of test responses and (c) reaction time (RT) measurements were added.…

In this study, we present the Pseudoscientific Belief Scale (PSEUDO; [alpha] = 0.90). The conceptual foundations of the scale include (a) a philosophically grounded and functional demarcation criterion between science and pseudoscience; (b) an analysis of the pseudoscientific status of science denialism, which is integrated into the scale; and (c)…

The Kaufman Test of Educational Achievement, 3rd edition (KTEA-3) is a popular battery for the assessment of students' academic skills. Its manual includes a series of confirmatory factor analyses to support construct validity. Its five-factor model did not include all available subtests in the battery and required covarying residuals between…

The biological concept has a broad scope and requires the visualisation of bioprocesses to provide complex understanding. Learning media can help visualise bioprocesses to enhance students' cognitive abilities. The study aimed to develop, test the practicality, and test the effectiveness of video animation in improving grade XI high school…

This study compares the psychometric properties of two popular teacher self-efficacy scales, namely, Teachers' Sense of Efficacy Scale (TSES) and Teacher Efficacy Scale (TES). This study was quantitative in nature and distributed the two scales to 287 preservice teachers in the USA and in Australia. Findings indicate that the two scales function…

Introduction: Self-regulation is the ability to adequately plan and manage one's own behavior in a flexible manner. It is a predictor of well-being, health, academic performance, among others. The psychometric characterization of the Self-Regulation Questionnaire-Abbreviated (CAR-abr.) composed of 17 items is presented. A versatile instrument,…

Communication as a skill is not something new; however, it has become much more important than ever before as the way and with whom we communicate have changed. That is why educators need to have valid and reliable tools to understand how this skill is perceived by students. This study aims to provide a valid and reliable secondary school…
