This professional practice paper is underpinned philosophically by the indisputable centrality of proof to the discipline of mathematics. Proof offers students the opportunity to deepen their own understanding of mathematical ideas, to construct and defend logical arguments, and to think critically about the veracity of mathematical statements.…

Naturalistic Developmental Behavioral Interventions (NDBIs) are evidence-based interventions implemented by the adults in a child's natural environment (e.g., by practitioners in classrooms). The social validity of this body of research may have an impact on the maintenance of practitioner implementation of NDBIs. We conducted a systematic review…

We sought to identify, examine, and summarize empirical literature focused on early childhood behavior interventions examined using a single case research designs (SCD) and published between 2001 and 2018. Using systematic procedures, 28 studies that met established inclusion criteria were identified, reviewed, and compared with respect to general…

The objective of this study was to adapt and validate the abbreviated version of the "Autism-Spectrum Quotient" (AQ-Short) in a sample of Spanish native adults. A total of 46 individuals with ASD, 41 ASD-relatives, 17 patients with schizophrenia spectrum disorders and 190 non-clinical adults were administered the Spanish version of the…

Background: Conceptual models are an essential phase in software design, but they can create confusion and reduced performance for students in Database Design courses. Objective: A novel Relational Data Model Validation Tool (MVTool) was developed and tested to determine (1) if students who use MVTool perform better than those who do not, and (2)…

Traditional Chinese medicine (TCM) is an important component of China's medical system. How to educate TCM practitioners in China, therefore, has become a crucial issue. To contribute to this issue, the current research identified the competency model of TCM practitioners in China and developed an evaluation for TCM students. We combined Bloom's…

The rational number knowledge of student teachers, in particular the equivalence of fractions, decimals, and percentages, and their comparison and ordering, is the focus of this article. An instrument comprising multiple choice, short answer and constructed response formats was designed to test conceptual and procedural understanding. Application…

Purpose: Recovery from aphasia is thought to depend on neural plasticity, that is, functional reorganization of surviving brain regions such that they take on new or expanded roles in language processing. To make progress in characterizing the nature of this process, we need feasible, reliable, and valid methods for identifying language regions of…

The New Zealand Government has announced a change package in response to a recent review of the National Certificates of Educational Achievement (NCEA). In this article, Charles Darr, a chief researcher at the New Zealand Council for Educational Research, outlines several elements of standards-based assessment that can usefully inform NCEA's…

The main purpose of this study is to develop a perceived stress scale based on Classical Test Theory (CTT) and Graded Response Model (GRM); to compare the parameters of the items in the scale that are tried to be developed according to both models, and to determine under which theory the measurement tool produces more reliable and valid results…

Setting performance standards is a judgmental process involving human opinions and values as well as technical and empirical considerations. Although all cut score decisions are by nature somewhat arbitrary, they should not be capricious. Judges selected for standard-setting panels should have the proper qualifications to make the judgments asked…

When we administer educational achievement tests, we want to be confident that the resulting scores validly indicate what the test takers know and can do. However, if the test is perceived as low stakes by the test taker, disengaged test taking sometimes occurs, which poses a serious threat to score validity. When computer-based tests are used,…

Cyberchondria is the name given to individuals who research their existing or imaginary diseases online. We developed a scale for measuring individuals' cyberchondria tendencies. The 36-item test form produced was applied to 1,200 participants (694 male and 506 female) residing in different provinces, with health problems in the previous month and…

The purpose of this study was to evaluate the stability and validity of a measure assessing sustainability of school-wide behavior interventions, the "School-Wide Universal Behavior Support Sustainability Index: School Teams" (SUBSIST). We assessed the stability of the SUBSIST across 3 years of measurement. We also assessed the…

The home environment has a critical influence on an infant's development and well-being. The Affordances in the Home Environment for Motor Development-Infant Scale (AHEMD-IS) is an instrument that has been developed to assess the home environment. This article illustrates the translation, validation, and cultural adaptation process of the AHEMD-IS…
