The Daily Life Experiences -- Frequency scale (DLE-F) measures the frequency of 18 racial discrimination experiences. Bifactor exploratory and confirmatory analyses indicated that the DLE-F is a unidimensional scale that yields valid and reliable scores. The DLE-F also showed evidence of measurement invariance by gender, convergent evidence, and…

Learners' difficulties with proof have been ascribed to their lack of understanding of functions that proof performs in mathematics, namely, verification, explanation, communication, discovery, and systematization. However, the extant mathematics education literature on validation of instruments designed to measure learners' beliefs about the…

This study aims to develop a scale for determining the anxiety levels of secondary school students in situations that require them to use their spatial skills. The scale was developed in three stages. In the first stage, after expert assessments, a pilot study was conducted. In the second stage, the scale was applied to all students (N=348)…

Recent research on entering college student assessment instruments and placement practices has been critical. Critics suggest that commonly used assessment instruments are inaccurate, misused, and lack predictive validity. This article describes valid criticisms and appropriate uses of assessment instruments. It also lists challenges and provides…

Broadly understood, values represent orientation guidelines for daily action, thinking, and feeling. Thus, they affect teachers' everyday work and are among their professional competencies. While general values and some single profession-specific values of teachers (e.g., responsibility) have already been investigated empirically, the current…

Effective leaders solve problems which prevent the achievement of organizational goals. We drew on theories of problem-solving and interpersonal behavior to propose a process model of quality problem-solving conversations, which was used to evaluate three leaders' attempts to resolve problems in conversation with those involved. Analyses revealed…

There is dearth of research in happiness among Africans, because of no indigenous scale among the plethora of scales used in measuring happiness. Consequently, an indigenous happiness scale was conceived using a three stage method (stage 1 = 48, stage 2 = 408, stage 3 = 1468 participants). A sequential mixed method approach and cross sectional…

The purpose of this research was to provide validity evidence for the Information Literacy Self-Efficacy Scale (ILSES), a widely used instrument that was constructed in 2006. The researchers were interested in investigating the validity of this instrument due to the evolution of the information environment that has taken place since the scale's…

In the literature there are more and more works dealing with cyberbullying and adolescents' perception of this phenomenon. In particular, we are interested in cyberbullying and the effects of cyberbullying on adolescent life. What is more, in 2020 the impact of COVID-19 has increased the digital presence of cyberbullying behaviours. This…

The Learning Climate Questionnaire (LCQ) measures teacher autonomy support in the classroom. There are various versions of the LCQ available, a 15-item full-scale version and a 6-item shortened version. Recent research suggests that using a 5-item version of LCQ is a more effective measure of teacher autonomy support. Using data from a sample of…

This article introduces the Creative Actions Scale (CAS), a Spanish self-report assessment of individual differences in creative actions. The CAS consists of independent scales that assess the frequency of engagement in everyday creative actions across seven domains: Literature, Plastic Arts and Crafts, Science and Technology, Scenic Arts, Music,…

There have been multiple calls to incorporate the teaching of scientific practices within science laboratory courses over the past decade. To accomplish this goal, changes must be made to the curriculum standards, instructional programs, and assessment-evaluation systems used in laboratory courses. One instructional program that can used in a…

Background: Valid measures to assess either small or assisted performed movements of people with profound intellectual and multiple disabilities (PIMD) are required. We analysed the construct validity of the Actiwatch-2 to assess movement in people with PIMD. Method: Twenty-two persons with PIMD were video recorded while wearing an Actiwatch-2. We…

This study investigates children's vocabulary knowledge in Finnish Sign Language (FinSL), specifically their understanding of different form-meaning mappings by using a multilayered assessment format originally developed for British Sign Language (BSL). The web-based BSL vocabulary test by Mann (2009) was adapted for FinSL following the steps…

Purpose: The purpose of this paper is to investigate the components of college students' readiness for connectivist learning in technology-enhanced learning environments through the development of the readiness for connectivist learning scale (RCLS). Design/methodology/approach: After the constructs of the scale had been identified, their items…
