This paper discusses an interesting, classic problem that provides a nice classroom investigation for dynamic geometry, and which can easily be explained (proved) with transformation geometry. The deductive explanation (proof) provides insight into why it is true, leading to an immediate generalization, thus illustrating the discovery function of…

Given the dearth of technically adequate universal screening tools in the Greek language, the current study sought to examine the psychometric properties of a 67-item universal screener (i.e. Integrated Teacher Rating Form; ITRF), that was originally developed in American English and then translated and implemented in Greek primary schools. The…

This study presents a reduced version of the Perception of Family Support Scale (PFSS)--a measure of family support designed for research and clinical purposes--and examine construct validity, invariance, and reliability evidence for scores obtained from the instrument. Data collection occurred in 2019. Using exploratory and confirmatory factor…

School-based universal well-being screening is proposed within the Multi-tiered Systems of Support approach to collect data on school and individual well-being. Universal screening allows for data-based informed decision, allocating each pupil or set of pupils in universal, selective and/or indicated structured interventions and supports. However,…

Given the recent attention to language-domain-specific grit in the field of SLA and the scarcity of research on the antecedents of L2 grit, we proposed a model that links L2 learners' basic psychological needs (BPN) (i.e. autonomy, competence, and relatedness), L2 grit (i.e. perseverance of effort (PE) and consistency of interest (CI)), and L2…

Biology education plays a vital role in nurturing the understanding of learners about the intricacy of life. Various efforts have emerged to strengthen learning biological concepts but there were still studies that showed that learners have low mastery in some aspects. To determine how well students understood various biological topics, including…

Students with autism spectrum disorders (ASDs) in Saudi Arabia are provided with the educational services they need in their local schools, but a standardized checklist is needed to measure the level of progress and the benefits acquired through the educational programs. This study aimed to standardize a version of Saudi performance norms on the…

Purpose: This study aims to delve into the interplay between didactic audiovisual translation (DAT) and computer-assisted language learning (CALL), exploring their combined impact on the development of intercultural competence (IC) among learners of English as a foreign language (EFL). Design/methodology/approach: Using a quasi-experimental…

This study explores the DT and PjBL to enhance creative, collaborative, and critical writing skills among EFL learners· A post-test-only quasi-experimental design was employed, involving 65 students from an English Education Program, aged 20 to 22, divided into three groups: DT, PjBL, and a integration of both· The instruments used to evaluate…

This study aims to evaluate the validity and practicality of a discovery-group learning model designed to enhance 21st century skills. The model includes a guidebook, teacher's book, student's book, and assessment sheet. The study involved three main stages: a preliminary study, prototype design, and evaluation. At the time of this article, the…

The New York State Education Department (NYSED) has a partnership with NWEA for the development of the 2024 Grades 3-8 English Language Arts Tests. Teachers from across the State work with NYSED in a variety of activities to ensure the validity and reliability of the New York State Testing Program (NYSTP). The 2024 Grades 6 and 7 English Language…

The study by Sanchez (2024a & 2024b) reveals evidence of grade inflation in high school GPA (HSGPA) from 2018 to 2022 despite stable or slightly decreased ACT scores. This study demonstrated that the predicted cumulative first-year hours earned at 2- and 4-year colleges decreased when the predictions were based on HSGPA alone, but predicted…

There is a tradeoff between scale length and psychometric concerns. The two are, in fact, directly linked. Generally, when scales are shortened, reliability is reduced, and when scales are lengthened, reliability is improved, provided the items added to the scale are comparable psychometrically (AERA et al., 2014). Scale reliability, in turn,…

Every school year, Miami-Dade County Public Schools (M-DCPS) students take a standardized state assessment in English Language Arts (ELA) and mathematics. During the 2022-2023 school year, a new version of the state assessment was implemented, titled the Florida Assessment for Student Thinking (FAST). The FAST is administered at three timepoints…

Despite its central place in the mathematics curriculum the notion of mathematical proof has failed to permeate the curriculum at all scholastic levels. While the concept of mathematical proof can serve as a vehicle for inculcating mathematical thinking, studies have revealed that students experience serious difficulties with proving that include…
