Windmill images and shapes have a long history in geometry and can be found in problems in different mathematical contexts. In this paper, we share and discuss various problems involving windmill shapes and solutions from geometry, algebra, to elementary number theory. These problems can be used, separately or together, for students to explore…

In this paper, Harel and Sowder's proof schemes of taxonomy were applied for identifying eighth grade students' learning of proof and proofing. This study aimed to examine what kind of proof schemes are used in geometry and measurement learning areas and student's skills in giving proof and their opinions about proof. Qualitative methods were…

This article describes the development of an instrument for examining schools as institutions where teaching practices and school structures provide opportunities and support for student imagination, creativity, and innovation, as well as initial comparisons using the instrument, using a sample of n = 5020 students and n = 268 teachers (n = 161…

The purpose of this article is to describe the methods and results used to establish the district capacity assessment's (DCA) content validity, response process validity, construct validity, internal consistency, and test-retest reliability. The DCA measures a district's ability to support school-level implementation of evidence-based practices…

The development of a teacher identity (TI) profoundly impacts teacher education program graduates' career intention and teaching practices. Existing studies on pre-service physical education teachers' teacher identity (PPET-TI) have used qualitative methods to focus on the dynamic and reflective features of TI. Quantitative studies that help…

Background: There is a lack of critical or empirical work interrogating the nature and purpose of evaluating technology use in education. Objectives: In this study, we examine the values underpinning the evaluation of technology use in education through field specialist perceptions. The study also poses critical reflections about the rigour of…

Schools are an essential setting for mental health supports and services for students. To support student well-being, schools engage in universal mental health screening to identify students in need of support and to provide surveillance data for district-wide or state-wide policy changes. Mental health data have been collected via anonymous and…

Science teachers are the primary agents in developing students' scientific literacy. Therefore, it is essential to identify teachers' perceptions of scientific literacy in order to increase students' scientific literacy. This study was designed to develop and validate an instrument of Indonesian science teachers' perceptions of scientific…

In this study, it is aimed to develop an organizational obedience scale that gives information about the obedience tendencies of white-collar employees working in the private sector. In this framework, thirty-one item seven-point Likert-type scale consisting of general expressions was prepared to measure obedience, which is the basis of employee…

The aim of this study was to develop and validate a multidimensional open thinking scale (OTS) in order to measure adult learners' open thinking as a key learning outcome of open educational practices (OEP) through a three-phase process of item generation, theoretical analysis, and psychometric analysis. Exploratory and confirmatory factor…

Purpose: Despite extensive research into communication-related parameters in dysarthria, such as intelligibility, naturalness, and perceived listener effort, the existing evidence has not been translated into a clinically applicable, comprehensive, and valid diagnostic tool so far. This study addresses Communication-Related Parameters in Speech…

Connecting and comparing across student strategies has been shown to be productive for students in elementary and secondary classrooms. We have recently been working on a project converting such practices from the K-12 level to the undergraduate classroom. In this paper, we share a particular instantiation of this practice in an abstract algebra…

Background: Supporting undergraduate students in science, technology, engineering, and mathematics (STEM) has been a persistent need. However, assessing the impact of support efforts can prove challenging as it is difficult to operationalize student support and subsequently monitor the combined impacts of the various supports to which students…

My dissertation research explored responder behaviors (e.g., demonstrating response styles, carelessness, and possessing misconceptions) that compromise psychometric quality and impact the interpretation and use of assessment results. Identifying these behaviors can help researchers understand and minimize their potentially construct-irrelevant…

Undergraduate students' choices and success in their career and life is influenced by their mathematics achievement and perception of themselves in life. Conceptual understanding of topics in undergraduate mathematics such as quantitative reasoning can be difficult for students with less sophisticated multiplicative reasoning than others. This…
