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…

This note is about 1000 words in length. We have been taught that this much information is contained in a single picture. But, Fig. 1 is so rich that four separate ideas can be obtained from it! The figure appears in "The Boy's Playbook of Science" by John Henry Pepper. Pepper tells us that this shows an "assistant standing on the…

This study explored the pedagogical strategies employed by grade 12, life-sciences teachers in township schools to teach complex concepts, such as genetics and meiosis, using improvised teaching resources. Resource constraints in South African township schools often limit learners' access to traditional teaching materials and technologies. In…

Teachers' goals and orientations underlie their instructional decision making and can make the difference between "talking the talk" and "walking the walk" when trying to change lab instruction. Schoenfeld's "Resources, Orientations, and Goals" (ROG) framework was employed to shed light on the challenges involved in a…

We present the development and evaluation of "da Vinci's Curse", a chemistry escape room experience designed to consolidate laboratory skills in a fun and interactive setting. Inspired by the maestro, Leonardo da Vinci, the escape room challenges students to complete a series of puzzles in teams to escape "da Vinci's Curse".…

Instructional coaching has emerged as a promising form of professional development for teachers. However, little is known about the background, contexts, professional responsibilities, and beliefs of instructional coaches who work with science teachers. This mixed-methods study focused on instructional coaches in secondary schools across the…

This inquiry sought to investigate the opportunities and potential challenges of engaging in a self-study approach as a strategy for enhancing professional growth during my teaching of the topic of evolutionary genetics to 24 twelfth-grade students. I had, for many years, experienced pedagogical deficits and shortcomings when teaching evolutionary…

The integration of digital learning tools in school science classes has garnered significant attention, prompting an investigation into their effects on student engagement and achievement. This study examines the impact of students' access to technology, teachers' digital competency, and the frequent use of digital tools on the engagement and…

The 21st century represents a time of worldwide interconnectedness that demands every individual to have digital knowledge and literacy. Science learning activities are important to help students learn and understand science and students' digital literacy. Learning that actively involves students will encourage students to find ideas. This study…

The 21st century education requires students to master the skills of Social Culture Awareness (SCA) and critical thinking, but the lack of use of local wisdom-based teaching materials is an obstacle in its achievement. This study aims to determine the validity and practicality of ecosystem e-modules integrated with local wisdom to improve…

The Interactive Whiteboard as a teaching tool, has been in use across schools and institutions in many countries. Bhutanese schools started using them for educational purposes in 2019. However, there is lack of evidence on their actual use and effectiveness in teaching physics to enhance students' learning. This study aimed to investigate the…

A distinctive aspect of science teaching is the use of various strategies to stimulate students' discovery-oriented curiosity. However, many instructional knowledge models overlook teaching methodology as a predictor of quality science instruction, as noted in the Technological Pedagogical Content Knowledge model. This study developed and tested a…

This multiple case study focused on the implementation of a computer-aided design (CAD) simulation to help students engage in engineering design to learn science concepts. Our findings describe three case studies that adopted the same learning design and adapted it to three different populations, settings, and classroom contexts: at the…

While laboratories have long been associated with introductory physics courses, there is doubt as to whether they positively impact student learning. Holmes and Wieman found that students who elected to take optional laboratories fared no better across a range of metrics than their counterparts who did not participate. In addition, these…
