The aim of the present study is to develop a national non-verbal cognitive ability test in Turkey. Test items were developed during the first stage and applied as a pilot study on 3,073 children in the age interval of 4 to 13. The test was given its final form based on the values of item difficulty, item distinctiveness, item total score…

Instruments for assessing secondary students' conceptual understanding of core concepts in biology are needed by educational practitioners and researchers alike. Most instruments available for secondary biology (years 9 to 12) focus only on highly specific biological concepts instead of multiple core concepts. This study describes the development…

Modeling reading comprehension processes is a critical task for Learning Analytics, as accurate models of the reading process can be used to match students to texts, identify appropriate interventions, and predict learning outcomes. This paper introduces an improved version of the Automated Model of Comprehension, namely version 4.0. AMoC has its…

Generalized Anxiety Disorder 7-item Scale (GAD-7) has been found to accurately assess the presence of generalized anxiety disorder (GAD) in various populations. However, despite showing good psychometric properties in assessing GAD symptoms, there is a need to further validate GAD-7 in milieu of the pandemic, considering that recent…

Research and practice have recognized the importance of informal learning--a specific type of active learning--for higher education contexts. University students learn not only in formally organized courses, but also in a self-directed and intentional way from fellow students, through trial and error, and by reflection. However, there has been a…

Purpose: We examined the properties of mean length of utterance (MLU) in Czech, a morphologically complex Slavic language. We compared the scores of MLU calculated in different units and based on different sample lengths and assessed its validity against another transcript and test-based measures. Method: One hundred nine children were recorded…

To investigate individuals' implicit beliefs--underlying assumptions about the self and the world--the present study validated the Korean version of the implicit theory of work scale for undergraduates, exploring its role in career-related behaviors and affect. The study used two different samples of 560 and 340 undergraduates who participated in…

Secondary school staff are often tasked with delivering mental health content to students, yet there has been little research on staff confidence to do so. Given the responsibility placed on staff to support student mental health, reliable and valid measures are needed to facilitate assessment of teacher confidence in the classroom and evaluation…

To examine the reliability and validity of revised Parental Phubbing Scale (PPS) and measure the level of parental phubbing, 701 Chinese children aged 3-6 years and their parents were investigated. The results indicated that: (1) the construct validity of the PPS was supported by the best-fit one-factor model; (2) concurrent validity was…

School-based universal screening in the social, emotional, and behavioral (SEB) domains allows for the early identification of students in need of SEB support. Importantly, equitable assessment in universal screening for the SEB domains is critical to engage in accurate and ethical data-based decision-making. Measurement invariance is one method…

The aim of this research is to develop a scale for determining pre-service teachers' attitudes towards recycling. The research was carried out using a quantitative research design. The research was carried out in the education faculties of two state universities located in the east and west of Türkiye. 284 pre-service teachers (62 males, 222…

Psychometrics is the field of designing tests and assessments to measure certain psychological concepts. It is chiefly concerned with two fundamental properties: reliability and validity. These properties are often influenced by confounding variables: other things that can influence performance but are not what you are trying to measure. Here, I…

Internal validity and measurement invariance of the Counseling Center Assessment of Psychological Symptoms-62 item (CCAPS-62) was examined via confirmatory factor analytic models among autistic (n = 1,268) and non-autistic (n = 3,776) college students. Findings reviewed the CCAPS-62 had a strong model fit and was invariant across groups.

This study illustrates how two secondary mathematics teachers used students' incorrect answers as they supported students' engagement in collective argumentation. Three ways of supporting argumentation when students contributed incorrect answers are exemplified, and the structures of these arguments are investigated. Then, by focusing on the…

The Campbellian validity typology has been used as a foundation for outcome evaluation and for developing evidence-based interventions for decades. As such, randomized control trials were preferred for outcome evaluation. However, some evaluators disagree with the validity typology's argument that randomized controlled trials as the best design…
