As the world is evolving, higher education is too. This includes online service-learning which in the past has been predominantly delivered in formats off-line or hybrid. This article describes some best practices to make the online service-learning experience beneficial for all who are involved and accessible to more students, including students…

This design case details a seven-year iterative design process to create an app for use in online physical education classes. Each iteration addresses the shortcomings of the previous version. The most recent iteration of the app allows students to use Fitbit™ devices to record heart rate data, which each student sees as progress toward course…

Although the benefits of undergraduate research for students are broadly understood, implementation of undergraduate research in the college classroom can be challenging. In this article, I explain how blogging assignments can be used to enable students to successfully complete course-long research projects and achieve many of the content and…

Electricity has shaped modern civilization in a way few other discoveries have. Nonetheless, few students successfully develop a basic understanding of voltage, current, and resistance or their mutual relationship in simple DC circuits. Despite teachers' best efforts in the classroom, so-called "alternative conceptions" often prevail…

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…

With the rapid development of information technology, the internet has emerged as a pivotal driving force in reshaping higher education paradigms. This paper delves into clustering algorithms and proposes an enhanced version, exploring how this enhanced clustering algorithm can be applied to blended teaching of digital electronic technology…

Learning Management Systems (LMS) or Learning Content Management Systems (LCMS) are the core of e-learning platforms and have evolved according to the development of new information and communication technologies. In this type of software there are many products on the market, some developed by the institutions themselves (in-house), others are…

In introductory electric circuits in middle school, students often carry strongly held alternative conceptions. Common to many of these is an idea of electric current as some kind of substance that originates from the battery and moves toward electronic components. Learners often argue that current influences those one by one as they are…

In online courses, much of the course communication occurs in public spaces. In synchronous courses, the video and audio channels represent a shared space, and although private chat messages are possible, they may not be substantial or frequent. In asynchronous courses, discussion boards are the allocated space for communication. In these…

This article outlines a three-phased approach to enhancing online student-instructor interaction using asynchronous threaded discussions: check-ins. These instructor-initiated touchpoints, a form of Classroom Assessment Technique, are staged throughout the grading period to help affirm online presence, clarify expectations, monitor performance,…

In this article, the authors share two examples of student engagement in visible, mathematical thinking through a Chalk Talk within the four walls of the classroom, as well as the connected spaces of online learning. Five steps for facilitating the Chalk Talk are outlined, with descriptions of teacher moves for each step. The silent thinking…

This article emphasizes the need for adult educators to adapt to the constantly evolving digital landscape. Traditional methods of professional development (PD) no longer suffice, so PD courses should strive to foster a lifelong learning mindset and encourage a culture of experimentation. The article outlines three strategies for creating an…

Teachers naturally engage in the act of 'noticing' as part of their daily practice. This specialised form of noticing, referred to as 'teacher noticing', involves a deliberate focus on specific aspects within the mathematics classroom. The author's PhD research has investigated how the events teachers notice and respond to online in Emergency…

This paper describes the adaptation of a flipped Biomedical Electronics course with laboratories to remote learning at the start of the COVID-19 pandemic. In class collaborative work on problem sets was replaced by group work (4-5 students) in Zoom breakout sessions. When the groups assembled at random for each class had sufficiently progressed on…

Online learning and teaching, accelerated by the global pandemic and rapid advancement of digital technology, require novel conceptual and analytical tools to understand better the evolving nature of online teaching. Drawing on the classical model of the instructional triangle and previous attempts to extend it, we propose the "Instructional…
