Previous research in mathematics education has explored teachers' conceptions of mathematics and its teaching and learning, and how their instructional tendencies (e.g., "traditional", "technological", "spontaneous" and "investigative") relate to these conceptions. However, empirical evidence on this topic…

Sensory issues are highly prevalent in autism and previous findings support a relationship between questionnaires of sensitivity and autistic symptoms and traits, whereas studies that examine this relationship through behavioural assessments of sensitivity are less consistent. The current study explores these differences and suggests that…

We report a Delphi Consensus modification and first validation study of the Autism Diagnostic Observation Schedule -- 2 with deaf children and young people (ADOS-2 Deaf adaptation). Validation included 122 deaf participants (aged 2-18 years), 63 with an Autism Spectrum Disorder (ASD). This was compared to a National Institute for Health and…

A negative association between symptoms of teacher burnout (e.g., emotional exhaustion) and students' academic outcomes has been demonstrated in previous research. Although, in theoretical models, it has been suggested that this association can be explained through changes in teachers' instructional behavior, these mediating processes have not yet…

Objective: Currently, no clinically feasible objective measures exist that are specific to the signs of adductor laryngeal dystonia (LD), deterring effective diagnosis and treatment. This project sought to establish concurrent validity of a new automated acoustic outcome measure, designed to be specific to adductor laryngeal dystonia (AdLD): the…

This research aims to develop the product of the life skill education program (LSEP) which is accurate, credible, and effective. This research used the Plomp model. The model covers the input, process, output, outcome and consists of instrument, scoring guidance, and good or bad criteria. The instruments used in the model are the questionnaire,…

Understanding the response process used by test takers when responding to multiple-choice questions (MCQs) is particularly important in evaluating the validity of score interpretations. Previous authors have recommended eye-tracking technology as a useful approach for collecting data on the processes test taker's use to respond to test questions.…

In the article, we prove 18 inequalities involving inradius, a length of one side and one additional element of a given triangle. 14 of these inequalities are the necessary and sufficient conditions for the existence and uniqueness of such a triangle. All proofs are based on standard methods of calculus and can serve as a good demonstration of the…

This study aimed to develop the "Students' Perception of Instructional Feedback Scale" (SPIFS) determining a framework related to the perception of instructional feedback by students. The sequential exploratory mixed method was used in the study. The study was conducted during the instructional design course offered to sophomores in the…

The Behavioral Inflexibility Scale (BIS) is a recently developed measure of behavioral inflexibility, defined as rigid patterns of behavior that contrast with the need to be flexible when the situation calls for it. In this study, we sought to replicate previous findings on the psychometric properties of the BIS in a community sample. Data for…

Foreign language classroom anxiety (FLCA) is a popular construct in applied linguistics research, traditionally measured with the 33-item Foreign Language Classroom Anxiety Scale (FLCAS). However, recent studies have started utilizing the eight-item Short-Form FLCAS (S-FLCAS). There is therefore a need, which this study addressed in five…

Evaluating digital competencies has become a topic of growing interest in recent years. Although several reviews and studies have summarized the main elements of progress and shortcomings in this area, some issues are yet to be explored. Very little information is available about the ways of ensuring the validity and reliability of the instrument…

One of the challenges of discussing validity arguments for machine scoring of essays centers on the absence of a commonly held definition and theory of good writing. At best, the algorithms attempt to measure select attributes of writing and calibrate them against human ratings with the goal of accurate prediction of scores for new essays.…

The aim of this paper is to describe the process of modification of the research tool designed for measuring the development of personal epistemology--"Standardized Epistemological Understanding Assessment" (SEUA). SEUA was constructed as an improved version of the instrument initially proposed by Kuhn et al. SEUA was proved to be a more…

This study aimed to develop a reliable and valid scale to reveal the cognitive biases of university students in context of analytical thinking skills. During scale development process, firstly, a 5-point Likert type scale pre-trial form consisting of 60 items was created. The pre-trial form was applied to 450 students in Afyon Kocatepe University.…
