In order to learn more about student understanding of the structure of proofs, we generated a novel genre of tasks called "Proof Without Claim" (PWC). Our work can be viewed as an extension of Selden and Selden's (1995) construct of "proof framework"; while Selden and Selden discuss how the structure of a proof can be discerned…

Proof validation plays a significant role in students' understanding and learning of mathematical proofs. Recent studies have shown that university students were lacking skills in proof validation and were challenged by the implementation of the appropriate acceptance criteria when validating proofs. Drawing on Habermas' construct and rational…

Tychonov's 1935 solution of the heat equation, exhibiting nontrivial heat fluxes spontaneously appearing along an isolated conducting rod initially held at zero degrees, has intrigued some specialists for almost a century. No doubt those practicing heat engineers who took mathematics seriously were initially relieved to learn that the construction…

PWW style are presented. The difference of evidence is based on various additional auxiliary constructions, which in itself is a "mathematical art" that the student can master as a result of much practice. The PWW are accompanied by GeoGebra applets containing HINT buttons that allow the student to get step-by-step help in completing the…

This study examined the predictive validity of musculoskeletal fitness tests for identifying sarcopenia in youth. The sample was 529 participants age 10 to 18 years. Indices included: total lean body mass (LBM) normalized for height (LBM index, LBMI, kg/m2), appendicular LBMI (aLBMI, kg/m[superscript 2]), and LBM to fat body mass (FBM) ratio…

The Autism Classification System of Functioning: Social Communication (ACSF) describes social communication functioning levels. First developed for preschoolers with ASD, this study tests an expanded age range (2-to-18 years). The ACFS rates the child's typical and best (i.e., capacity) performance. Qualitative methods tested parent and clinician…

The purpose of this article is to develop a context-bound scale on student alienation around core problems experienced by students at the university level. The confirmed dimensions of the scale shall be correlated with the dimensions of the student's ICT motive scale. The study is based on two sets of cross-sectional samples of Kashmiri university…

Clearinghouses are influential repositories of information on the effectiveness of social interventions. To identify which interventions are "evidence-based," clearinghouses review intervention evaluations using published standards of evidence that focus primarily on internal validity and causal inferences. Open science practices can…

Background: Evidence-based assessments for people with aphasia (PWA) in Greek are predominantly impairment based. Functional communication (FC) is usually underreported and neglected by clinicians. This study explores the adaptation and psychometric testing of the Greek (GR) version of The Scenario Test. The test assesses the everyday FC of PWA in…

Aphasia assessment is the initial step of a well-structured language therapy. Therefore, it is reasonable to underline that the assessment tools need to consider the typological and cultural characteristics of the language. A group of international researchers in the Collaboration of Aphasia Trialists have been adapting the Comprehensive Aphasia…

The purpose of this paper is to demonstrate and describe why alternating treatments design (ATD) researchers should consider employing a no-treatment series during the alternating treatments phase. To identify limitations associated with excluding this design element, we obtained examples of ATD studies published in five school psychology journals…

Traditional cloze tests (such as the CBM-maze) may be poor measures of comprehension processes beyond the single sentence level. This paper presents an alternative, a deep cloze test with gaps that are strategically chosen to assess comprehension beyond the sentence level. To fill each gap, the reader has to draw global cohesion inferences during…

Purpose: Auditory feedback is thought to contribute to the online control of speech production. Yet, the standard method of estimating auditory feedback control (i.e., reflexive responses to auditory-motor perturbations), although sound, requires specialized instrumentation, meticulous calibration, unnatural tasks, and specific acoustic…

The purpose of this study is to discern and discuss issues with relevance to the tension between contextuality and generalisation, which recurrently are identified over time in research reviews of teaching methods. The 75 most cited reviews on teaching methods listed in the Web of Science from 1980 to 2017 were analysed. Since our interest is the…

Background: Much confusion exists about the underachievement of gifted students due to significant variations in how the phenomenon has been identified. From a review of the literature, five methods were found to be commonly used to identify gifted underachievement. Aims: The purpose of the study was to assess the equivalence of the commonly used…
