This study explores the effect of in-person schooling on youth suicide. We document three key findings. First, using data from the National Vital Statistics System from 1990-2019, we document the historical association between teen suicides and the school calendar. We show that suicides among 12-to-18-year-olds are highest during months of the…

School closures induced by COVID-19 placed heightened emphasis on alternative ways to measure student learning besides in-person exams. We leverage the administration of phone-based assessments (PBAs) measuring numeracy and literacy for primary school children in Kenya, along with in-person standardized tests administered to the same students…

Parental text messaging interventions are growing in popularity to encourage at-home reading, school-attendance, and other educational behaviors. These interventions, which often combine multiple components, frequently demonstrate varying amounts of effectiveness, and researchers often cannot determine how individual components work alone or in…

Purpose: Our aim was to evaluate the psychometric properties of the online administered format of the Test of Narrative Language--Second Edition (TNL-2; Gillam & Pearson, 2017), given the importance of assessing children's narrative ability and considerable absence of psychometric studies of spoken language assessments administered online.…

In this study, a mathematical modeling activity was designed and implemented in a seventh grade classroom. The students were first expected to examine a given mathematical model of a problem that is based on a real life situation and then build a model depending on their own criteria. The mathematical modeling activity which was designed by the…

Mobile phones usage had extensively penetrated into the world. A study done by the Malaysian Communication and Multimedia Commission (MCMC) found that in the first quarter of year 2010, the penetration rate for cellular phone in Malaysia is 121 per 100 inhabitants. Penetration rate over 100% occurs because of multiple subscriptions (Adnan, 2012).…

Background: The risks and opportunities associated with the use of technologies are of growing research interest. Patterns of technology usage illuminate these opportunities and risks. However, no studies have assessed the usage patterns (frequency, duration, and intensity) and related factors in young people with intellectual disabilities.…

pH determination is an essential experiment in many chemistry laboratories. It requires a potentiometric instrument with extremely low input bias current to accurately measure the voltage between a pH sensing electrode and a reference electrode. In this technology report, we propose an open-source potentiometric instrument for pH determination…

Extending teaching beyond the classroom walls has been known for its potential to promote inquiry learning in various disciplinary domains. Current technologies can enhance these benefits, especially by enabling supports for seamless learning between contexts. But even without technology, teachers tend to refrain from implementing outdoor inquiry…

Technology is in a constantly evolving and changing structure since the existence of mankind. Because of this dynamic structure, technology fulfills a number of functions such as facilitating people's lives, time, profit from work, profit from cost, making life more enjoyable. At the same time, technology is used in all areas of life, and it also…

Educational technology (ed tech) coaches can help teachers and students integrate iPad affordances into their teaching and learning. A brief overview of affordance theory is provided. While investigating the under-researched practices of ed tech coaches, the authors identified iPad affordances and tabulated these, revealing links between the…

College student personal technology use in the classroom, namely cell phones and laptops, has become rampant. This review of literature examines research concerned with the impact of student unstructured technology use in the face-to-face college classroom and academic performance (learning). Student motivations for and descriptions of use are…

Propagation of sound waves is one of the fundamental concepts in physics. Some of the properties of sound propagation such as attenuation of sound intensity with increasing distance are familiar to everybody from the experiences of daily life. However, the frequency dependence of sound propagation and the effect of acoustics in confined…

Background: Informing policy and practice with up-to-date evidence on the social determinants of health is an ongoing challenge. One limitation of traditional approaches is the time-lag between identification of a policy or practice need and availability of results. The Right Here Right Now (RHRN) study piloted a near-real-time data-collection…

This study looks into the relationship between nomophobia and loneliness, and the effects of smartphone and mobile internet use among adolescents. A total of 301 adolescents were employed for the study and the data were collected via Nomophobia (NMP-Q) and UCLA Loneliness Short-Form (ULS-8) Scales. The study was conducted in a relational survey…
