A new device for teaching the physics of sound, specifically demonstrating the wavelengths of standing sound waves, is here described. I define a "Lincoln's Tube" as any hollow tube that uses lights (LEDs typically) to demonstrate the presence of sound standing waves. The name is chosen intentionally to recall a Ruben's Tube or a Kundt's…

Semiconductor devices, usually made from silicon wafers, are present in the electronic gadgets that we use on a daily basis. In an introductory physics class, the textbook usually devotes a few pages to these devices and moves on. As a result, students may readily forget the material or fail to see how it relates to their lives. A solution is to…

Researchers have hypothesized and, in some cases, shown that hypothetical learning trajectories (LT)s can be effective tools in teaching, but implementation, across individual teachers, varies. From the literature base, we have identified six ways researchers have hypothesized teachers might be able to use LTs in their work as teachers:…

The purpose of this note is to describe the mathematics that emanates from the construction of an origami box. We first construct a simple origami box from two rectangular sheets and then discuss some of the mathematical questions that arise in the context of geometry and algebra.

In this commentary, the authors suggest that a paramount job for adolescent literacy assessment is to create more equitable outcomes for all students. The authors propose that the use of learning scales and micro-progressions fills a void and demonstrate how their use can provide better information to teachers and yield information that can…

Problem based learning model has been widely implemented in various fields and educational contexts since it challenges students to learn through engagement in a real problem. The purpose of this study was to investigate the influence of a Problem-Based Learning (PBL) model, learning method, and learning motivation on entrepreneurial attitudes.…

Reality TV -- or certain design-oriented TV shows -- may be better known for their focus on competition, but what we actually see when we look more closely are models of collaboration and assessment that can illuminate important principles of classroom learning. Erin Furtak reflects on the ways that three of these shows -- The Great British Baking…

This study explores the role of conceptual coherence in science teacher learning of science-specific formative assessment. Conceptual coherence refers to the alignment of ideas about teaching and learning and may be difficult with certain teaching practices, like formative assessment, that have a central role in accountability mechanisms in…

Fixation is one of the major obstacles that individuals face in creative idea generation contexts. Several studies have shown that individuals unintentionally tend to fixate to the examples they are shown in a creative ideation task, even when instructed to avoid them. Most of these studies used examples formulated with high level of specificity.…

Advocacy outcomes are not self-evident. Identifying advocacy outcomes is extremely difficult because they are often intangible, arising from (personal) interactions, and they are not always traceable. This challenges conventional evaluation methods, which is recognized in the advocacy evaluation literature. However, current evaluation methods…

Every time we join an organization, we go through the socialization process, which is often not as explicit as we might like. Although organizations often provide handbooks for role-related information, there is no such formal structure for cultural information. In order to understand the socialization process and the value it has for both the…

Children's tendency to delay gratification predicts important life outcomes, yet little is known about how to enhance delay of gratification other than by teaching task-specific strategies. The present research investigated the effect of exposing children to a model who experiences the exertion of willpower as energizing. In two experiments, 86 4-…

Drawing on an actor-network articulation of evaluation theory, this article examines the Wisconsin Department of Public Instruction's transition from a punitive teacher evaluation model to a promising new development and support model, which focuses on teacher growth and environmental adjustments. Supported by dozens of interviews and observations…

Creative activism is an approach to education that asks: 'What can happen when we take learning outside the classroom and think of it happening everywhere?' Two charities--House of Imagination and Cambridge Curiosity and Imagination--have been asking this question in their creative place-making programmes working with socially engaged artists and…

University students in other disciplines without prior knowledge in statistics and/or programming language are introduced to the statistical method of decision trees in the programming language R during a 45-minute teaching and practice session. Statistics and programming skills are now frequently required within a wide variety of research fields…
