The two most popular decision-making processes are tossing a coin and playing rock, paper, scissors. In the activity described in this article, students find the theoretical probabilities of winning a coin toss and a round of the rock, paper, scissors game. They next devise strategies to win and test them out. Students then compare the theoretical…

In this study, two sections of undergraduate Introductory Anatomy and Physiology taught in the traditional face-to-face format (n = 58) was compared to two hybrid classes (n = 38) using the flipped-classroom model taught by the same instructor. Formative and summative examination scores were compared to determine the effect of the different…

Although text readability has traditionally been measured based on simple linguistic features, recent studies have employed natural language processing techniques to develop new readability formulas that better represent theoretical accounts of reading processes. This study evaluated the construct validity of different readability formulas,…

During the spring of 2020, K-12 schools were turned upside-down. The COVID-19 pandemic essentially forced all schools across the nation to close their doors and move their learning environments online. The switch to remote learning put a great deal of stress and responsibility on teachers at all levels. The content taught by family and consumer…

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,…
