In this article we show that the electrostatic field intensity of a uniformly charged straight line equals that of the corresponding arc of a circle charged with the same linear density. This new method greatly simplifies the calculation of the electrostatic field of a system consisting of uniformly charged straight lines.

Across a wide range of studies, researchers often conclude that the home environment and children's outcomes are causally linked. In contrast, behavioral genetic studies show that parents influence their children by providing them with both environment and genes, meaning the environment that parents provide should not be considered in the absence…

Derreck Kayongo is an entrepreneur and the former CEO of the National Center for Civil and Human Rights. He founded the Global Soap Project (now acquired by Clean the World), a humanitarian aid organization for collecting discarded and unused soap from thousands of hotels worldwide, reprocessing it, then distributing it to in-need populations…

The issue of connecting research evidence with practice referred to as evidence-informed practice (EIP) has received considerable critical attention in the field of education. However, assessment literature has failed to fully acknowledge the significance of this issue. This conceptual paper concentrates on the process of informing classroom…

Principal supervisors often find themselves drawn into managing logistical and operational matters, instead of helping principals become more effective instructional leaders. Yet Meredith Honig and Lydia Rainey contend that principal supervisors need to make principals' instructional leadership their primary focus. Drawing on their work with…

This article presents an approach to teaching how social media impacts the public-sector workplace. Social media creates new challenges for both public administration practitioners and teachers. Yet, the topic does not yet have wide-scale discussion in the public administration education literature. After a review of four approaches to public…

In an effort to achieve stronger, curricular alignment and establish a more concrete relationship between literacy theory and instructional practice, curricular redesign within an undergraduate, literacy methods course commenced. With a clear rationale for why course redesign was necessary, a collective vision rooted with intention and focused on…

This articles describes the beginnings of the American Montessori Society (AMS). The AMS was founded in 1960, in Greenwich, CT. Its small office was located above a bakery. Founder Nancy McCormick Rambusch described the stresses of the young organization, one that was "trying to keep ahead of the mounting mail and unanswered telephone calls,…

Personal hygiene is critical for preventing the spread of infection. One important component of personal hygiene is handwashing. This review summarizes research on behavioral strategies to address handwashing in children, offers areas for additional research, and suggests a treatment package to teach handwashing to young children.

Teachers from all grade levels and subjects are continuously seeking effective instructional strategies to help students learn. Mnemonics represent a diverse set of research-based methods that help students remember primarily factual information. Teachers can infuse various types of mnemonics within their instruction to support student learning.…

The objectives of this research were to (1) develop virtual commerce using the design thinking process to promote modern entrepreneurship, (2) carry out a suitability assessment of this process, and (3) evaluate digital entrepreneurship competency (DEC). The research process was therefore divided into 3 phases in accordance with these aims. The…

The teaching-learning process must constantly overcome the barriers imposed by rapid scientific and technological advances, as well as changes in the profiles of students and access to information. This study intended to analyze the perceptions of students and professors of medical courses of the teaching-learning strategies used in physiology at…

An online peer-assessment system typically allows students to give textual feedback to their peers, with the goal of helping the peers improve their work. The amount of help that students receive is highly dependent on the quality of the reviews. Previous studies have investigated using machine learning to detect characteristics of reviews (e.g.,…

Genetics plays an increasing role in modern life as evidenced by the development of revolutionary techniques such as CRISPR-based genome editing and the rise of personalized genome services. However, genetics is difficult to learn; known issues include its abstract nature, different scales, and technical language. Pedigree analysis is a…

Predictors of student academic success do not always replicate well across different learning designs, subject areas, or educational institutions. This suggests that characteristics of a particular discipline and learning design have to be carefully considered when creating predictive models in order to scale up learning analytics. This study…
