Oral Interviews as Assessment

TL;DR I have begun using oral interviews as a replacement for traditional written tests and quizzes. There are many advantages for faculty and students, including elimination of paperwork, better chances for understanding students’ state of comprehension, a more relaxed environment, and no possibility for gaming for points. The ongoing pandemic has amplified many questions I […]

So you want to be a GlowScript developer? Here’s how!

TL;DR Developing for GlowScript requires setting up a rather extensive, but straightforwardly installed, development environment. Actual coding is done in JavaScript.  GlowScript is an online programming environment inteneded to be used to teach computation in introductory physics, although it has other applications and purposes. Although GlowScript users write code in Python (Specifically VPython, which is […]

A Response to Physics Today’s Article on the Benefits of a Master’s Degree in Physics

I have submitted the following comments to Physics Today in response to Toni Feder’s article “A physics master’s degree opens doors to myriad careers” published in the April 2019 issue, pp. 22-25. I must add two cautions to Toni Feder’s piece on the benefits of a physics master’s degree. After I completed my MS in […]

Vector Formalism in Introductory Physics VI: A Unified Solution for Simple Dot Product and Cross Product Equations

TL;DR: Simple vector dot products and cross products may be “undone” using formal methods consistent with Gibbsian vector algebra. Writing the cross product and dot product of an unknown vector relative to a given vector in a canonical form allows a well known vector identity to be used to isolate the unknown vector. Special cases […]

Vector Formalism in Introductory Physics V: Two Equations, One Solution

TL;DR: Solving seemingly trivial dot product and cross product equations leads to an astonishing result, namely that they have the same solution, which can be derived both geometrically and algebraically. Establishing this common solution is an important step in motivating formal Gibbsian vector algebra. In the previous two posts, I demonstrated that the simple dot […]

Almanacs in Astronomy Classes

In memory of my maternal grandmother Dorothy Marie Blalock Clark (1912-1997) TL;DR: Ubiquitous farmers’ almanacs are an inexpensive printed source of accurate astronomical information despite being mostly advertising vehicles. This information can be used in the classroom to generate questions and learning about not only astronomy, but also history, mathematics, and computation.  Thanks to my […]

Two Different Obsevers, Same Class

I’m going to present two observers’ accounts of a classroom observation that took place on April 24, 2018 beginning at 9:30 am. The class was an introductory astronomy class with eight students on the roster, five of which stopped attending without withdrawing (faculty are now forbidden “by law” from withdrawing students) and three of which […]
