The purpose of the research is to develop a valid and reliable perception scale that can measure the perception of math teachers (198) and science teachers (120) towards private lesson. In the validity studies, the exploratory factor analysis was made with the SPSS 25.0 package program after that the confirmatory factor analysis was made with…

This paper reports how I addressed the issue of extensive missing values in my PhD study, "Digital Competencies of High School Mathematics Teachers". I collected data using an online survey. Several methods exist to address the issue of missing values. I utilised multiple imputation (MI) as it provides more accurate results. The mean…

This study aimed to perform a scale adaptation to determine students' perceptions of a classroom learning environment. The sample of the study consisted of 337 students for exploratory factor analysis and 1,639 students for confirmatory factor analysis. The scale known as My Class Activity adapted in this study was developed by Gentry and Gable…

Background: Body experience is an important facet of psychosocial functioning and health. However, to date no test exists to measure body experience in adults with mild intellectual disability and borderline intellectual functioning (MID-BIF). We therefore adapted the Body Experience Questionnaire (BEQ) to this group, resulting in the BEQ-mb, and…

As artificial intelligence (AI) becomes more prevalent, so does the interest in AI ethics. To address issues related to AI ethics, many government agencies, non-governmental organizations (NGOs), and corporations have published AI ethics guidelines. However, only a few test instruments have been developed to assess students' attitudes toward AI…

A common observation in Transformative Learning (TL) literature is the scarcity of ways to gauge the extent of personal transformation. This is despite a recorded history of more than four decades and the existence of multiple schools of thought in TL. Also, there has been insufficient exploration of the personal transformation of profession…

The aim of this research was to conduct a review of studies using four-tier tests to detect misconceptions in physics education. Fifty-eight studies whose main purpose was to develop a four-tier misconception test and eleven studies whose purpose was to determine learners' misconceptions using a four-tier diagnostic test without test development…

The main aim of this study is to build a new observational coding system for sibling interactions (Sistema de Codificación de Interacciones entre Hermanos -- SCIH) and to analyze its psychometric properties and validity. First, this study offers the first Spanish adaptation of a self-report questionnaire to measure sibling relationships that…

The objectives of this research were to construct and verify a mathematics diagnostic assessment on addition and subtraction basis for grade 4 students in Buriram Primary Educational Service Area Office 3. The research samples consisted of 440 Prathomsuksa 4 students selected by adapting the multi-stage random sampling method. The research…

Recently, adaptive test approaches have become a viable alternative to traditional fixed-item tests. The main advantage of adaptive tests is that they reach desired measurement precision with fewer items. However, fewer items mean that each item has a more significant effect on ability estimation and therefore those tests are open to more…

Response styles introduce construct-irrelevant variance as a result of respondents systematically responding to Likert-type items regardless of content. Methods to account for response styles through data analysis as well as approaches to mitigating the effects of response styles during data collection have been well-documented. Recent approaches…
