Although the notion of "assumptions" is important in mathematical activity as early as the elementary school, there is limited research on how to help elementary teachers develop "mathematical knowledge for teaching" related to assumptions. In this paper, we discuss the theoretical foundation and implementation of an…

Understanding the extent to which caregivers perceive active shooter lockdown drills in K-12 schools as physically and emotionally safe for their children is pertinent, yet little empirical evidence exists. Negative parental perceptions of drills can lead to decreased student participation and compliance and amplify public concerns associated with…

How parents value and address emotions with their children is essential for children's emotion socialization. This study developed and validated the short Parent-Child Emotion Communication questionnaire (PEC), which measures the extent to which parents appreciate emotions, consciously discuss their own and their child's emotions with their…

"Tests of Aptitude for Language Learning" (TALL) is an openly accessible internet-based battery to measure the multifaceted construct of foreign language aptitude, using language domain-specific instruments and L1-sensitive instructions and stimuli. This brief report introduces the components of this theory-informed battery and…

During times of crisis, such as the COVID-19 pandemic, the evaluation of educational programs becomes crucial for making evidence-based decisions. This study aims to validate and pilot an assessment instrument tailored to evaluate an innovative national reading program in Chile, particularly during the critical phase of post-pandemic educational…

This article seeks to explore the convergent validity of (and thus the consistency between) a few popular generative artificial intelligence (AI) robots in evaluating popular mobile learning apps' usability. The three robots adopted in the study were Microsoft Copilot, Google PaLM, and Meta Llama, which were individually instructed to accord…

Indicator 4.7.1 of the Sustainable Development Goals (SDGs) measures the extent to which Global Citizenship Education (GCED) and Education for Sustainable Development (ESD) are incorporated into educational documents. An appropriate framework is crucial to accurately monitor the level of incorporation, but a framework that can confirm validity is…

Test development is a complicated process that demands examining various factors, one of them being writing items of varying difficulty. It is important to use items of a different range of difficulty to ensure that the test results accurately indicate the test-taker's abilities. Therefore, the factors affecting item difficulty should be defined,…

The study aims to introduce to the Turkish culture a measurement tool that has proven validity and reliability in determining the level of quiet quitting among teachers. It involves the analysis of the validity and reliability of the Quiet Quitting Scale, as the scale is adapted to the Turkish culture. The scale, originally developed in English,…

Acadience Reading Diagnostic: Comprehension, Fluency, and Oral Language Assessment (CFOL) is an individually administered diagnostic assessment published by Acadience Learning for students in kindergarten through sixth grades. The measure purportedly provides diagnostic information in story coherence/text structure, listening and reading…

Mathematical language (or the content-specific words in mathematics) has repeatedly shown to be related to mathematical abilities in preschool and in the early grades of primary education. Research in this field has predominantly focused on young children's quantitative and spatial language. At the same time, recent research has discovered that…

Purpose: The purposes of this study were to calculate the confirmatory factor analysis in the measurement model using robust measures (McDonald's omega and Cronbach's alpha) to ensure the reliability of the proposed scale and to explore the measurement invariance of the scale per the participants' gender. Design/methodology/approach: The…

The Standards Self-Efficacy Scale (SSES) was developed to assess 204 pre-service teachers' self-efficacy beliefs to utilize as part of the InTASC professional standards for teachers. Principal component analysis revealed the nuanced factor structure of the SSES to measure standards-based self-efficacy. The SSES was compared to the well-established…

With Artificial intelligence (AI) literacy gaining more and more attention at the kindergarten level, it is becoming critical to assess the AI literacy levels of kindergarten children and develop appropriate courses to enhance their foundational AI knowledge and skills. This study proposes and validates a comprehensive AI literacy assessment tool…

This dissertation develops and evaluates the validity and reliability of the Skills Self-Efficacy Scale for Adolescents (SSES-A), a measure designed to assess adolescents' self-efficacy in critical future skills: problem-solving, communication, creativity, collaboration, and critical thinking. Anchored in Social Cognitive Theory and Psychometric…
