Introduction: Wearable activity monitors have been developed for jump height assessment, but the Blast Athletic Performance monitor has not yet been validated, and it remains unclear if the Blast can track changes across a sports season. Methods: Collegiate women's volleyball players (n = 20) wore the Blast monitor (waistband) while performing…

Objective: To assess the convergent validity and reliability of joint angle measurements from a new video goniometer iPhone/iPad application separately in adults, older and young children. Design: Cross-sectional. Setting: Child care and university environments. Participants: Fifty-four adults (mean SD=22.5 [plus or minus] 4.5y), 20 older children…

The aim of this study is; to investigate the effects of differential training method on hand and leg visual reaction time in high school tennis trainees. 24 trainees (12 girls, 12 boys) attending a tennis course in a high school participated in the study voluntarily. It was determined that the mean age of the participants was 15.00±0.00 years,…

Increasing school dropout rates are a problem in many educational systems, with student disengagement being one significant factor. Learning analytics is a new field with a key role in educational institutions in the coming years. It may help make strategic decisions to reduce student disengagement. The use of technology in educational…

Accurate body composition assessment, which includes fat mass (adipose tissue mass, FM), fat-free mass (FFM), and percent fat mass (%FM) is needed to evaluate health and treatment efficacy. The current study compared body composition estimates obtained from the Norland Elite® DXA, BodPod®, and iDXA® before and after a 12-week exercise intervention…

The present study validates a new procedure that combines continuous measures of proximity (Ubisense) and vocalization (LENA) into measures of peer social interaction. The data were collected from 4 boys and 5 girls (ages 2-3 at the outset) on 8 separate days (3-4 hours per day) over the course of an academic year. Teacher reports of friendship…

Elementary school mathematics instruction aims to develop children's understanding of both numerical and spatial mathematics--two key areas of mathematical learning. The present study explored how learning within one of these areas may impact the other. Specifically, it investigated whether a measurement-to-number intervention designed to increase…

A study with K-9 Greek students was conducted in order to evaluate how the declarative knowledge acquisition was affected by incorporating Arduino experiments in secondary Chemistry Education. A Digital Application (DA) that blends the use of the Arduino sensors' experiments with digital educational material, including Virtual Labs (VLs), was…

Introduction: Physical education (PE) can contribute to total daily physical activity (PA) among children. In consequence, the Spanish Ministry of Education, Culture and Sport has developed 16 teaching units focused on increasing PA levels during PE lessons, called "Unidades Didácticas Activas" (UDA; Active Teaching Units). Objectives:…

Heart rate (HR) by time curves could be useful as a measure of treatment fidelity (TF). The purposes were to describe the frequency of common recording irregularities (e.g. errors) observed during exercise, validate a process to correct those errors, and determine whether there is a clinically meaningful benefit to data correction. In total, 1895…

Background and Context: Sports and technology are often pitted as being at odds with one another. While there are several educational activities that make reference to sports we seldom see sports used as an authentic context for learning computing. Objective: We describe the design of Data in Motion, a curriculum that considers the bi-directional…

The interest in achieving improved acoustical conditions in classrooms has increased in the last years. Some experiments on acoustics phenomena using smartphone applications appear in the recent bibliography. In this paper, we present a proposal for active learning about room acoustics for high school and undergraduate students. Students work on…

This article reports on the introduction of a simple, portable, low-cost, and hands-on spectral tool for first-year chemistry students to use inside the laboratory and its spontaneous dissemination outside of the laboratory. The Mini Spec is a refinement of the Schwabacher minispectroscope in terms of simplicity and language load on the students.…

Described here is a well established opensource geophysics project to monitor atmospheric infrasound 24/7. It employs a modern digital, I[superscript 2]C enabled differential pressure sensor--unlike the older analog devices more commonly used. Python software automatically uploads plots whilst data is stored in standard ".mseed" format…

Anatomy and Physiology courses taught at community colleges tend to focus laboratory hours primarily on anatomy as opposed to physiology. However, research demonstrates that, when instructors utilize active learning approaches (such as in laboratory settings) where students participate in their own learning, students have improved outcomes, such…
