Although differences in DNA methylation have been associated with both syndromic and idiopathic autism, differential methylation has not been examined previously with respect to sex differences. The goals of this study were to (1) identify differences in the DNA methylation profiles of lymphoblastoid cell lines derived from a subgroup of severely…

Introduction: The current school is strongly focused on student performance. Each student faces a large number of learning tasks, which place considerable demands on them, arouse in them a different degree of interest, evoke a different degree of commitment to work, are associated with different expectations or have a different degree of…

In this study, we analyzed data of heart rate and pulse amplitude collected by undergraduate students in a physiology lab course during and after the diving reflex. On average, heart rate was reduced 21% at 15 seconds and 29% at 30 seconds during diving. Pulse amplitude generally decreased but with greater individual variation. There is no…

This article explores the issue of identifying guessers -- with a specific focus on multiple-choice tests. Guessing has long been considered a problem due to the fact that it compromises validity. A test taker scoring higher than they should through guessing does not provide a picture of their actual ability. After an initial description of issues…

This study was conducted to search the effect of respiratory muscle training on aerobic, anaerobic endurance, and respiratory parameters in primary school students. 32 volunteer students, between the ages of 13-14, participated in this study. The volunteers were divided into experimental (n = 15) and control groups (n = 17). The experimental group…

Online teacher education is an important alternative in response to the problem of teacher shortage. The format of interaction is critical in leveraging social and intellectual connection between learners. Yet, few studies have examined this issue in online teacher preparation. In this study, we examined two commonly used interactional formats…

Number naming, or knowledge of math numerals, has been described as a gatekeeper skill in preschool math development because it is necessary for later math tasks such as calculation. This article describes a small group intervention piloted with 10 preschoolers found to be at risk for delays in early numeracy development during universal…

This paper adopts a semiotic perspective on mathematical learning according to Peirce, in which the actions on material arrangements are considered the bases for diagrammatic work. The focus is on the learner's actions using digital and analogue material arrangements which are the starting point for the reconstruction of the learner's mathematical…

While both the 1918 influenza (aka Spanish flu) and the 2020 COVID-19 pandemics were devastating, the 1918 influenza pandemic was considered worse. Its origins are still debated, but it was first identified in the United States at Fort Riley, an Army base in Kansas. According to the Centers for Disease Control and Prevention (CDC), an estimated…

Metacognition is the ability to think about thinking. One of the learning models in geometry is the van Hiele model, which consists of learning phases and geometry thinking level. However, geometry learning strategy in Indonesia does not stress metacognition and geometry thinking level. Hence, this study aims to examine the effectiveness of…

Volunteering is an activity that enables the development of an individual's competency and is also an area of interest both of society and the academic community. This article aims to compare the motivation for volunteering and the experience of volunteering with students within helping professions and economics. For the purpose of this research,…

Academic freedom is often regarded as an absolute value of higher education institutions. Traditionally, its value is related to such topics as tenure, and the need for academic work to be free from undue political influence and other pressures that can challenge time-consuming research processes. However, when an analysis of student freedom…

The aim of this study is to examine the effects of extended micro-teaching practices on foreigners' views on motivation, anxiety and process of learning Turkish. In the study, an exploratory sequential design, one of the mixed research designs in which quantitative and qualitative research techniques are used together, was applied. The study…

Purpose: The goal of this study was to determine the ability of the AzBio speech recognition in noise (SRN) test to distinguish between groups of participants with and without a self-reported SRN disorder and a self-reported signal-to-noise ratio (SNR) loss. Method: Fifty-four native English-speaking young adults with normal pure-tone thresholds…

Statisticians have developed propensity score methods to improve generalizations from studies that do not employ random sampling. However, these methods rely on assumptions whose plausibility may be questionable. We introduce and discuss bounding, an approach that is based on alternative assumptions that may be more plausible. The bounding…
