Rheology is an enormously far-reaching branch of physics (or physical chemistry) and has a number of different guises. Rheological descriptions define fluids, semi-solids and conventional solids, and the application of this science defines the performance and utility of materials and substances as diverse as foods (such as yogurt and marmalade),…

Harmonics arise naturally from the resonances in strings and pipes. A video demonstration (Ruiz 2016 "YouTube: Tuba Harmonics" (https://youtu.be/souhEzOP9c4)) is provided where a tubist (coauthor Holmes) produces a phenomenal 24 harmonics using a single tuba pipe length by controlling the buzz of his lips. The frequencies of the…

Laboratory experiments provide students a tangible means of understanding dry, abstract concepts. A simple and engaging introductory wet chemistry laboratory has been developed relating quantum mechanics to color, which has been implemented for a class of about 600 students per academic year for over three years at Brown University. Color is an…

"Cannabis sativa" is a species of plant with a rich, yet controversial history. Although the utility of cannabis has been documented for thousands of years; during the last century, research has led to a more advanced understanding of its mechanism of action and therapeutic potential. Accordingly, there has been an explosion of interest…

Rural education is a short board of China's education. It is of great significance to strengthen the construction of the teacher team in rural middle schools for Rural Revitalization in the new era. The problem of structural shortage of teachers, reflected by the phenomenon of "what biology teachers teach is not what they learned" in…

Physics lab courses are integral parts of an undergraduate physics education, and offer a variety of opportunities for learning. Many of these opportunities center around a common learning goal in introductory physics lab courses: measurement uncertainty. Accordingly, when the stand-alone introductory lab course at the University of Colorado…

[This paper is part of the Focused Collection on Curriculum Development: Theory into Design.] We argue that teaching learning sequence (TLS) design needs to be further developed through the explicit articulation of methodology, which comprises the theoretical commitments regarding research and how those give rise to methods for design,…

A sudden pivot to online instruction required instructors to rapidly acquire new knowledge. Several online communities were built to satisfy their need for professional development. One such community, the Facebook group "Strategies for Teaching Chemistry Online", generated thousands of posts and comments about how to adapt chemistry…

On March 19, 2020, Argentina's government decided to close academic institutions for an indefinite time in an attempt to contain the spread of the COVID-19 pandemic. Since the University established that, when the quarantine ends, 5 weeks will be reserved for face-to-face activities that could not be carried out virtually (laboratory lessons and…

During the COVID-19 pandemic, many educators have been required to offer their courses online. A particular challenge is the implementation of practical laboratory experiments in the field of materials science. The central questions are the following: How can students carry out laboratory experiments at home? How are applications on mobile devices…

The need to develop clean-energy storage systems, harvesting technologies, and new functional materials are but a few of the many contemporary challenges in the domain of science today. To address these challenges, problem solving has become a key skill of the 21st century. It is generally documented, however, that experts and students differ in…

This article examines the backgrounds and pedagogical evolution of twelve community college (CC) human anatomy and physiology faculty participating in a larger study known as the Community College Anatomy and Physiology Education Research (CAPER) project. Using qualitative analysis of interviews based on Luft & Roehrig's (2007) Teacher Belief…

The aim of this research was to investigate the effect of science course which is based on inquiry based learning approach on seventh grade students' scientific process skill levels. Both quantitative and qualitative data collection methods were used in the study. Considering that both quantitative and qualitative data collection methods were…

Purpose: This paper aimed to explore secondary science teachers' views on Resource Folio as an effective tool to improve their PCK through interpretation of own teaching practice. Method: The study was conducted in qualitative approach following multiple case study method. Three secondary science teachers were purposively selected as participants…

Poster presentations to communicate scientific knowledge/understanding are a commonly used assessment tool. It can be a challenge for students (and staff!) to deliver clear information with minimal text on the poster. We have found that this format did not encourage imaginative project topics or posters. To enhance communication skills,…
