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…

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.…

When learning about scientific phenomena, students are expected to "mechanistically" explain how underlying interactions produce the observable phenomenon and "conceptually" connect the observed phenomenon to canonical scientific knowledge. This paper investigates how the integration of the complementary processes of designing…

Ethnography is an exceptionally difficult subject to teach and learn in a classroom setting. This article, written by an ethnography professor and five graduate ethnography students, reflects on how a short-term and collectively executed fieldwork study can help alleviate this problem. Within three months, we logged over 100 hours of observations…

Data-based instruction (DBI) is a process in which teachers use progress data to make ongoing instructional decisions for students with learning disabilities. Curriculum-based measurement (CBM) is a common form of progress monitoring, and CBM data are placed on a graph to guide decision-making. Despite the central role that graph interpretation…
