Little is known about whether a widely used mindfulness measure in adults--the Five Facet Mindfulness Questionnaire (FFMQ)--is also reliable and valid in adolescents. The current study evaluated the psychometric properties of a 20-item short-form FFMQ in a sample of 599 high school students (M[subscript age] = 16.3 years; 49% female) living in the…

Generative artificial intelligence (GenAI) has profoundly reshaped how graduate students conceptualise, design and conduct academic research in higher education. While current metrics predominantly focus on technology acceptance and usage patterns, they often neglect the diverse cognitive engagements in graduate students' integration of GenAI…

Background: Family involvement in youth care and special education is referred to as family-centered practice (FCP). Research on FCP, for example in relation to the effectiveness of youth care and special education, is challenged by a lack of validated instruments that measure youth professionals' family-centered attitudes and actions that is…

When cognitive and educational tests are administered under time limits, tests may become speeded and this may affect the reliability and validity of the resulting test scores. Prior research has shown that time limits may create or enlarge gender gaps in cognitive and academic testing. On average, women complete fewer items than men when a test…

Studies are emerging documenting the experience of fatigue, exhaustion and loss of functioning that has long been described by autistic adults as autistic burnout. New assessment tools are needed to enable identification and diagnosis. Here, we sought to identify factors associated with severity, develop an autistic burnout assessment and test the…

The study aimed to test the psychometric properties of a Portuguese adaptation of the "Adolescent Students' Basic Psychological Needs at School Scale" (ASBPNSS). For this, we used data from a sample of eighth graders (N = 1648; M[[subscript age] = 14.1 years; 46.9% girls) from Portugal. Cronbach alpha and omega coefficients showed the…

Nowadays, the assessment of student performance has become increasingly technology-based, a trend that can also be observed in the evaluation of scientific reasoning, with more and more of the formerly paper-based assessment tools moving into the digital space. The study aimed to examine the reliability and validity of the paper-based and…

This research aimed at developing a reliable scale to determine in-service language teachers' perceptions about teaching pronunciation and contributing to the English Language Teaching (ELT) field. The participants of the study consisted of 132 English language instructors working in 42 secondary and high schools in the 2021 to 2022 academic year…

In the context of improving the quality of teacher education, the focus of the present work was to adapt the Mentoring for Effective Primary Science Teaching instrument to become more universal and have the potential to be used beyond the elementary science mentoring context. The adapted instrument was renamed the Mentoring for Effective Teaching…

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…

This paper describes a study that focused on developing, validating and standardizing a dyscalculia test, henceforth called the Dyscalculia Test. Out of the 4,758,800 students in Nigeria's upper primary and junior secondary schools, I randomly drew a sample of 2340 students, using a multistage sampling procedure that applied various sampling…

Teachers' digital competence (DC) is an important condition for the effective application of technology in education. Although several DC tools have been designed, adjustments to digital education and pedagogical or professional components are still scarce. Therefore, this study aims at developing a new instrument for assessing teachers' DC…

This research goal to develop a multiple-choice closed-ended test to assessing and evaluate students' digital literacy skills. The sample in this study were students at MTsN 1 Blitar City who were selected using a purposive sampling technique. The test was also validated by experts, namely 2 Doctors of Physics and Science from Yogyakarta State…

This study sought to develop an Academic School Climate Scale measuring students' perceptions of the learning environments at their schools. With a pilot sample of 1,265 students and validation sample of 14,773 students in Grades 4-12 in schools across the U.S., results of EFA and CFA supported a bifactor model with a general factor and three…
