Fluency is an important construct in clinical assessment and in cognitive taxonomies. In the Cattell-Horn-Carroll (CHC) model, Fluency is represented by several narrow factors that form a subset of the long-term memory encoding and retrieval (Glr) broad factor. The CHC broad classification of Fluency was evaluated in five data sets, and the CHC…

This article describes the revision of Vespia, Heckman-Stone, and Delworth's (2002) Supervision Utilization Rating Form (SURF) and validation of the resulting Adapted SURF. The Adapted SURF is designed to provide supervisors with a cleaner measure of supervisee behaviors that contribute to effective supervision.

According to Acceptance and Commitment Therapy (ACT), "psychological flexibility" refers to an individual's ability to maintain mindful awareness of his or her thoughts and emotions in the present moment while behaving according to his or her personal values. Psychological inflexibility could set the foundation for emotional distress and…

The "5 Cs of PYD Model" is an influential theory involving the role of Intentional Self-Regulation (ISR) in positive youth development (PYD). The model, which was developed with U.S. populations, has recently been used in other cultural contexts and, as such, the measurement invariance of the ISR-PYD model across cultural contexts must…

The Occupational Work Ethic Inventory (OWEI) has been widely used to measure work ethic constructs by professionals in the fields of Career and Technical Education (CTE) and Human Resource Development (HRD). However, there are circumstances when a shorter instrument would have advantages, especially when a measure of work ethic is needed along…

Teachers' teaching approaches have become an important issue in the search of quality in education and teaching because of their effect on students' learning. Improvements in teachers' knowledge and awareness of their own teaching approaches enable them to adopt teaching process in accordance with their students' learning styles. The Approaches to…

Educating students with behavioural, emotional and social difficulties requires a thorough systematic approach with the focus on academic instruction. This study addresses the development of a tool, consisting of two questionnaires, for measuring systematic academic instruction. The questionnaires cover the Plan-Do-Check-Act cycle and academic…

In this article, we revisit the concept of strong differentiability of real functions of one variable, underlying the concept of differentiability. Our discussion is guided by the Straddle Lemma, which plays a key role in this context. The proofs of the results presented are designed to meet a young audience in mathematics, typical of students in…

A proof is a connected sequence of assertions that includes a set of accepted statements, forms of reasoning and modes of representing arguments. Assuming reasoning to be central to proving and aiming to develop knowledge about how teacher actions may promote students' mathematical reasoning, we conduct design research where whole-class…

We present results from a classroom-based intervention designed to help a class of grade 10 students (14-15 years old) learn proof while studying trigonometry in a dynamic geometry software environment. We analysed some students' solutions to conjecture-and-proof problems that let them gain experience in stating conjectures and developing proofs.…

Purpose: This study aims to design and validate a conceptual and practical model of co-creation. Co-creation, to design collaborative new products, services and processes in contact with users, has become more and more important because organisations increasingly require multidisciplinary collaboration inside and outside the organisation to…

This study compared accuracy of energy expenditure (EE) prediction models from accelerometer data collected in structured and simulated free-living settings. Twenty-four adults (mean age 45.8 years, 50% female) performed two sessions of 11 to 21 activities, wearing four ActiGraph GT9X Link activity monitors (right hip, ankle, both wrists) and a…

This study investigates 3 hypotheses about proof-based mathematics instruction: (a) that lectures include informal content (ways of thinking and reasoning about advanced mathematics that are not captured by formal symbolic statements), (b) that informal content is usually presented orally but not written on the board, and (c) that students do not…

In multiple-choice tests, the quality of distractors may be more important than their number. We therefore examined the joint influence of distractor quality and quantity on test functioning by providing a sample of 5,793 participants with five parallel test sets consisting of items that differed in the number and quality of distractors.…

This study aimed to explore self-reported domain-specific creativity in relation to the level of empathy, systemizing, and the Big Five personality dimensions. The research sample consisted of 1112 college students to whom the Kaufman Domains of Creativity Scale (K-DOCS), the Creative Achievement Questionnaire (CAQ), Baron-Cohen's empathy and…
