Background: Distance education is a growing sector in higher education but continues to lag in medical imaging education. Educators continue to utilize the traditional teaching method stating technology as the major challenge to adding distance education to their curriculum. Lack of faculty development and information technology support are the…

This preregistered, randomized field experiment tested the effectiveness of a brief deep breathing intervention on children's concurrent physiological arousal in naturalistic settings (N = 342; M[subscript age] = 7.48 years; 46% female; 53% Asian, 26% White; 21% other race/ethnicity). The treatment consisted of an animated video that introduced…

The purpose of this case study was to explore the nature of instructors' gestures as they teach Euclidean transformations in a synchronous online setting, and to investigate how, if at all, the synchronous online setting impacted the instructors' intentionality and usage of gestures. The participants in this case study were two collegiate…

Background: Human Papillomavirus (HPV) infection is the most common sexually transmitted infection in the US affecting almost 60% of college women ages 20 to 24 years. At one west coast community college, two thirds of males and half of females were unaware of HPV vaccine recommendation through age 26 years. Objectives: This aim of this project is…

Research aims: Educational research showed that a crucial role in determining student achievement and school effectiveness is played by teachers. At the same time, teachers differ widely in their impact on student performances and previous studies has not been able to identify the sources of this variation. As a consequence, "teacher…

There is a lack of educator persistence and responsibility to assist the influx of adult learners entering programs in universities and colleges. A research study by Teachers College Columbia University's (2013) showed there was a 50% greater chance of failure for online students versus face-to-face students and recommends the creation of online…

In this article, we describe the purpose and the process of video-cued ethnography. Using examples primarily from the Children Crossing Borders study, we outline six basic elements of video-cued ethnography including site selection, participant-observation, filming, editing, focus group interviews, and comparative analysis. We detail some of the…

The air drag constant for different nose shapes of projectiles is determined with the help of a simple method combining a projectile launcher, video tracking technique and spreadsheet computer code for simulating the motion. A projectile launcher with low-cost components is developed to study air drag in projectile motion. The launcher is based on…

In this work we describe a teaching proposal to calculate the eccentricity of the Moon's trajectory by applying a geometrical technique. The values of the ratios between the Earth-Moon distance and the diameter of the Moon at apogee and at perigee were calculated from a kinematic model associated with a geometrical technique of image analysis. The…

Purpose: The powerful activity profile of elite soccer match play has not been documented appropriately to inform specific maximal power assessment and development criteria. The aims of the current study were to develop a reliable soccer-specific powerful action (SSPA) notational analysis coding system that could be used to compare frequency and…

We describe the use of student-generated video content to assess students' engagement with, and understanding of, problem-solving skills. In this framework, students are tasked with using technology to create videos that show them working through, and explaining solutions to, challenging calculus exercises. The videos are then posted online,…

In this paper, I share an analysis process that emerged from and evolved during my efforts to study children's musical learning from video recordings of choral rehearsals. Because written transcription would not adequately represent nonverbal data within social interactions, I developed a technique that (a) enabled me to disseminate understandings…

Lecture capture is widely used within higher education as a means of recording lecture material for online student viewing. However, there is some uncertainty around whether this is a uniformly positive development for students. The current study examines the impact of lecture capture introduction and usage in a compulsory second year research…

Despite the fundamental importance of plants to our very survival, student interest in plant biology is in decline as technology draws us further away from nature. Here we introduce "Plant Tracer" (http://www.planttracer.com), a Matlab-based program, which can quantify time-lapse videos of plant movement. We demonstrate that Plant Tracer…

Agricultural and environmental scientists collaborated with educational technology researchers to create multimedia learning tools to fill gaps in student understanding of key concepts that undergraduates often struggle with, including sorption, cation exchange capacity, inner and outer sphere bonding, and soil system complexity. These resources…
