This study presents an experimental method that illustrates and quantifies the Doppler-effect phenomenon. Two stages of the experimental process were carried out. First, a simplified ripple tank was used to depict the Doppler effect, and the whole experiment was recorded by a digital camera. Second, video analyses of the recorded experiment were…

The drag effect on a falling ball caused by air is a conventional subject in the most well-known textbooks of classical mechanics and fluid dynamics. Further, there are some papers that employ video analysis to track objects movements in the air making it possible to obtain position data as a function of time and its graphs. However, none of them…

Background: Within the ambit of the Fourth Industrial Revolution (4IR), the use of technology-based tools within teaching and learning is advancing rapidly at education institutions globally, including the teaching and learning of mathematics. Learners and teachers have challenges with teaching and learning fractions in mathematics. A learner's…

The use of video is commonplace for professional preparation in education and other fields. Research has provided evidence that the use of video in these contexts can lead to increased noticing and reflection. However, educators now have access to evolving forms of video such as 360 video. The purpose of this study was to adapt and validate an…

As more educators integrate their curricula with online learning, it is easier to crowdsource content from them. Crowdsourced tutoring has been proven to reliably increase students' next problem correctness. In this work, we confirmed the findings of a previous study in this area, with stronger confidence margins than previously, and revealed that…

This longitudinal study aimed to investigate infants' spontaneous object interactions during naturalistic longitudinal observations in a day care centre in Japan. Infants' and caregivers' interactions during free play time were videotaped. The main focus related to how infants' object interactions changed during locomotor development. Observations…

This paper explores the joyful subjectivity of LGBTQ+ youth. The study analyzes It Gets Better videos for their evolving narratives of queer lives. Using feminist theories, I find complex manners in which the videos script and surveil queer subjects, articulate the transitions associated with coming out, and embrace joyous refusals of victim…

The purpose of this mixed-methods sequential explanatory study was to investigate the effects of watching text-relevant video segments on reading comprehension of a culturally unfamiliar text when technical words are present or absent. Therefore, 44 adult English Language Learners (ELLs) with higher-intermediate to advanced English language…

Every demographic in the American education sector has been impacted by the forced migration from face-to-face to online learning caused by COVID-19. This research looks at six faculty members' perceptions regarding their views on social presence and what influences or drives their instructional practices at Nichols College. Social presence is a…

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…

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…

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…

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…
