This exploratory study reports on characteristics of proof production and proof writing observed in the work of first-year university students who took part in workshops on the theorem prover LEAN (https://leanprover.github.io). These workshops were voluntary and offered alongside a transition to proof module in a UK university. Through…

This study was conducted to examine whether newly enrolled 9th grade students were ready to directly engage in the theoretical discursive process from the perspective of Duval's Cognitive Model. The sample of the study was comprised of 51 newly enrolled 9th grade students between the ages of 14 and 15, who had not received any prior geometry…

A prior study developed the Computational Thinking Scale (CTS) for assessing individuals' computational thinking dispositions in five dimensions: decomposition, abstraction, algorithmic thinking, evaluation, and generalization. This study proposed the Developmental Model of Computational Thinking through validating the structural relationships…

Growing interest in interdisciplinary (ID) understanding has led to the recent development of four ID assessments, none of which have previously been comprehensively validated. Sources of evidence for the validity of tests include construct validity, such as the internal structure of the test. ID tests may (and should) test both disciplinary (D)…

We present a psychometric evaluation of a revised version of the "Cybersecurity Concept Inventory" ("CCI"), completed by 354 students from 29 colleges and universities. The CCI is a conceptual test of understanding created to enable research on instruction quality in cybersecurity education. This work extends previous expert…

One of the objectives of this research is to develop and validate the Instructional Material Motivation Scale for Single-Use (IMMS-SU) instrument in the Turkish context. The IMMS-SU was developed and validated in a two-phased process on a sample of 1654 students. The Exploratory Factor Analysis revealed that IMMS-SU included 14 items…

This article outlines an active learning project that gives students hands-on experience in developing an undergraduate situational judgment test. The five-part activity models the process for constructing a situational judgment test--a tool commonly used for employee selection in organizations. The project is designed to help students assimilate…

Identifying impediments to learning can help both instructors and students. In this study students (N = 222) from across the nation listed concepts from research methods they found the most challenging--"potholes" or impediments to learning, and also rated the difficulty of various concepts from the class. We also measured student…

The present study investigated evidence of the construct validity of scores from the Scales for Assessing Emotional Disturbance Rating Scale (SAED-3 RS), which is designed to help identify emotional disturbance (ED) as defined by U.S. law and regulations. The purpose of this research was to evaluate the degree to which SAED-3 RS scores differed…

High stakes test-based accountability systems primarily rely on aggregates and derivatives of scores from tests that were originally developed to measure individual student proficiency in subject areas such as math, reading/language arts, and now English language proficiency. Current validity models do not explicitly address this use of aggregate…

Social and emotional learning (SEL) has become essential in educational settings and human development. Federal policy has begun to incorporate SEL factors into education accountability metrics. Schools, institutes, and scholars have started implementing SEL in K-12 educational contexts. Social interactions and emotions are a daily part of…

The purpose of this research was to explore the factors associated with online learning anxiety by carefully designing, developing, and providing preliminary validity and reliability evidence of a scale to measure undergraduate students' online learning anxiety. We created a conceptual framework to organize the literature surrounding online…

Teachers' beliefs can have powerful consequences on instructional decisions and student learning. However, little research focuses on how teachers' beliefs about the role of race and gender in mathematics teaching and learning influence educational equity within classrooms. This gap is partly due to the lack of studies focused on variation within…

Purpose: The aim of this study was to identify variability in word-learning mechanisms used by late-talking children using a longitudinal study design, which may explain variability in late-talking children's outcomes. Method: A cohort of typically developing children (n = 40) and children who were classified as late-talking children at age 2;0…

While group projects are popular in middle school classrooms, limited research has been conducted on how to grade them. Teachers usually assign the same score to all group members, which hardly reflects the achievement level of any student. This study explores the feasibility of utilizing peer and self-assessments for grading group projects for…
