Internalizing and externalizing problems are common targets for school mental health screening. Prior research supports the interpretation of scores from the Youth Internalizing Problems Screener (YIPS) and the Youth Externalizing Problems Screener (YEPS), which were developed separately yet intended as companion measures. We extended previous…

Mathematics modelling is a vital competency for students of all ages. In this study, we aim to fill the research gap about valid and reliable tools for assessing and grading mathematical modeling problems, particularly those reflecting multiple steps of the modelling cycle. We present in this paper the design of a reliable and valid assessment…

Introduction: The furtherance of educational, social and occupational inclusion has led to increasing acceptance of people with intellectual disabilities as full members of the community. However, attitudes and behaviors towards these people are not always positive. Method: Taking the model of the FUNDOWN School of Life as the theoretical basis,…

A questionnaire was recently developed for the use with the Spanish-speaking, and evidence have been provided about the construct internal validity by means of structural equation modelling. In this paper, two research questions were considered: (i) What new evidence does application of the Rasch model provide regarding the validity of this…

Purpose: Civic education is a central mission of public schools, and deeper learning of civics--learning that is complex and adaptive--is the goal. However, assessment of deeper civic learning is limited. Therefore, we aimed to develop an assessment model and test of deeper learning in the common high school civics course taught across the U.S.…

Certain behaviors, especially when adopted by a majority, can help limit the magnitude of climate change. In this cross-sectional study, the stages of change from the Transtheoretical Model (TTM) are applied to environmentally-significant behavior. We develop and test a new scale -- the Climate Change Stages of Change Questionnaire (CCSOCQ) -- for…

Vertical scales are frequently developed using common item nonequivalent group linking. In this design, one can use upper-grade, lower-grade, or mixed-grade common items to estimate the linking constants that underlie the absolute measurement of growth. Using the Rasch model and a dataset from Curriculum Associates' i-Ready Diagnostic in math in…

The research aims to develop a valid and reliable scale to determine secondary school students' perceptions of role modeling. The survey design model, which is a quantitative research method, was used in the research. The study's sample comprised 500 students enrolled in three secondary schools in Turkey during the 2018 spring semester. Data for…

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…

While teacher-to-teacher knowledge-sharing is promising for professional learning and improving teaching quality, it lacks integration and timeliness in schools because teachers are usually weak at knowledge-sharing. Despite this weakness, principals as knowledge-sharing leaders can make a difference. There is still limited research about this…

While research has shown that students' epistemic beliefs can be a strong predictor of their academic performance, cognitive abilities, or self-efficacy, studies of this topic in computer education are rare. The purpose of this study was twofold. First, it aimed to validate a newly developed questionnaire for measuring students' epistemic beliefs…

School climate is an essential ingredient of student well-being and academic success. Although it has been studied extensively, only a few well-validated instruments are available for the assessment of school climate. The aim of this study was to assess the factor validity and measurement invariance of the Socio-educational Environment…

The development of assessments as part of the funded LOCUS project is described. The assessments measure students' conceptual understanding of statistics as outlined in the GAISE PreK-12 Framework. Results are reported from a large-scale administration to 3,430 students in grades 6 through 12 in the United States. Items were designed to assess…

Large scale international assessments depend on invariance of measurement across countries. An important consideration when observing cross-national differential item functioning (DIF) is whether the DIF actually reflects a source of bias, or might instead be a methodological artifact reflecting item response theory (IRT) model misspecification.…

Research in self-determination has expanded in recent years, especially in the special education field. Instruments to measure self-determination in students with disabilities are not available in the Romanian language, and this issue has led to the development of the current study, a cultural adaptation , and validation of "The ARC's…
