Understanding fast speech can be an ongoing challenge for English learners of all levels. Even after years of study, learners might be accustomed to clear, slow classroom English and struggle with understanding the reductions that proficient speakers of English use in fast, fluent speech. Many online resources exist to help students learn about…

We report on a distance learning experimental project for chemistry-major students on the synthesis of ethyl dodecanoate (C[subscript 11]CO[subscript 2]Et), a model for biodiesel, considering green chemistry principles. Thus, we employed a "recyclable acid catalyst" (an ionic liquid) and used chemometrics and microwave heating (MW) to…

As political participation across the globe grows increasingly contentious and accusations of "fake news" and "post-truth" politics rise, the how, where, and why of civic learning in schools are called into question. In contrast, multimodal practices such as digital video production continue to promote youth engagement and…

Selective mutism is a disorder that can negatively impact a student's learning. It can be treated effectively if it is understood as an anxiety related condition and if it is diagnosed early. Intervention strategies can be complex and are therefore difficult for educational practitioners to implement. Simplifying intervention by addressing the…

Newton's cradle is a well-known physics toy that is commonly used by teachers to demonstrate conservation laws in mechanics. It can also be used to investigate the physics of colliding objects, by recording motion of the balls on video film. Various experiments are described using 3-ball and 5-ball cradles, showing how different types of collision…

The vertical bounce of a plastic egg was investigated by dropping the egg on a horizontal surface and filming the result with a video camera. If the egg is dropped on one end then it bounces just like a spherical ball. If the top end of the egg is pointing forwards or backwards when it lands on the surface, or if the egg is spinning when it lands,…

Here we describe a systematic approach towards creating effective screencast based modules for teaching computational techniques in remote and online modalities. We adopted a multi-stage approach to create screencast videos that replaced in-person demos and active learning content in a finite element analysis based class. The stages include…

The January 2018 issue of "The Physics Teacher" saw two articles that featured the RSpec Explorer as a supplementary lab apparatus. The RSpec Explorer provides live video spectrum analysis with which teachers can demonstrate how to investigate features of a diffracted light source. In this article I provide an introduction to the device…

Since its inception in 2005, YouTube has grown to become one of the most trafficked online platforms in the world. Accordingly, second language (L2) research interest on the topic has also increased, with studies investigating its use in formal and informal settings. Given this, the goal of this conceptual paper is to identify patterns within L2…

In this article, the authors share frameworks for problem types and students' reasoning about integers. The authors found that all ways of reasoning (WoRs) were used across grade levels and that specific problem types tended to evoke particular WoRs. Specifically, students were more likely to use analogy-based reasoning on all-negatives problems…

This article introduces Performing Ourselves, an interdisciplinary community dance program that utilizes principles from dance education and dance/movement therapy to serve beginning dancers in grades PK-8 in schools and community centers. After defining the integrative elements of the curriculum, the article outlines how Performing Ourselves used…

The abundance of information available to us every day continues to increase, largely because of society's reliance on the internet. While the internet provides access to a wealth of information, information may be inaccurate or irrelevant because anyone can publish content on the internet. As a result, it is critical for individuals to develop…

This paper uses the PBS Nova show "Mind Over Money" to introduce a number of topics in behavioral finance. Instructors can also use the video as a jumping off point for expanding the discussion to the "second generation" of behavioral finance, where many of the decisions that differ from what are considered optimal are due to…

The action of hammering a nail into wood is examined in terms of the force, momentum and energy required. Some unexpected experimental results are also presented.

Pinhole camera photography is explored using a set of entomology pins due to their known pin diameters and availability in a variety of sizes. A procedure to prepare removable-lens digital cameras for pinhole photography is described. A video is included showing a set of ten insect pins and how to fit the camera with pinhole apertures. Formulas…
