Ribeiro, Williams J. M.; de Sousa, J. Ricardo – Physics Teacher, 2021
During elementary physics courses, many examples in mechanics are studied without considering air resistance effects. We can mention, for example, projectile motion and free fall, among many others. Only brief studies of such systems in classical mechanics courses consider linear air resistance (F[subscript drag] [is proportional to] v), which is…

Sharpe, J. P.; Yee, C. – Physics Teacher, 2021
The Young's two-slits experiment is arguably one of the most famous and beautiful experiments in physics. In introductory physics labs the experiment is almost exclusively carried out using a laser, and it is introduced this way in some introductory physics textbooks. In the case of laser illumination, light passes directly through the slits and…

Isom, Elliot; Dowda, Reade; Olt, Phillip – International Journal for the Advancement of Counselling, 2022
Traditionally, counselor education instruction has taken place in the face-to-face format. However, with the shift toward online learning, more counselor education programs are incorporating distance education into the curriculum. Counselor educators continue to study the impact of distance education methods on student learning, but studies are…

Pence, Harry E.; Pence, Laura E. – Journal of Chemical Education, 2022
Nationally, as the chemical community aspires to become more diverse, it is essential to make students of all races, ethnicities, gender expressions, and physical abilities feel welcomed and represented in the introductory courses in the field. One way to accomplish this goal is to present examples of scientists who are not traditionally included…

Lisensky, George; Dauzvardis, Fabian; Jacquez, Tess – Journal of Chemical Education, 2021
Chemical energy storage and use is a critical part of a sustainable world. In this laboratory experiment, students construct and use an inexpensive hydrogen fuel cell to power a calculator or a clock. The reusable cells are prepared from plastic syringes and a nickel mesh that is coated with a palladium metal catalyst by electroless deposition.…

Redish, Edward – Physics Teacher, 2022
When students are learning to use math in physics, one of the most important ideas they need to learn is that equations are not just calculational tools; they represent relationships between physical variables that change together (co-vary). How much a change in one variable or parameter is associated with a change in another depends on how they…

DiLisi, Gregory A. – Physics Teacher, 2022
On April 14, 1912, the British passenger liner R.M.S. "Titanic" struck an iceberg. The ship sank in a fraction of the time designers had estimated following a worst case scenario. The purpose of this article is to examine the atmospheric refractive phenomena that might have played a significant role in obscuring the iceberg from…

Whitaker, Douglas; Unfried, Alana; Bond, Marjorie – Statistics Education Research Journal, 2022
The Survey of Attitudes Toward Statistics (SATS) is a widely used family of instruments for measuring attitude constructs in statistics education. Since the development of the SATS instruments, there has been an evolution in the understanding of validity in the field of educational measurement emphasizing validation as an on-going process. While a…

Bartels, Jared M.; Schoenrade, Patricia – Psychology Learning and Teaching, 2022
The Implicit Association Test (IAT) has been widely discussed as a potential measure of "implicit bias." Yet the IAT is controversial; research suggests that it is far from clear precisely what the instrument measures, and it does not appear to be a strong predictor of behavior. The presentation of this topic in Introductory Psychology…

Mungan, Carl E. – Physics Teacher, 2021
Ampère's law is presented in introductory physics as a relation between the line integral of the magnetic field around a closed loop and the net current crossing any open surface spanning that loop. By allowing the surface to pass between the plates of a charging parallel-plate capacitor, Maxwell realized that this law is incomplete and introduced…

Gould, Robert – Teaching Statistics: An International Journal for Teachers, 2021
The growth of the data culture has led to calls for improving data literacy among primary and secondary students and their teachers. One approach to improving data literacy is to teach a course devoted to data science but, given the lack of consensus over the term "data science," just what should an introductory data science course…

Osorio, Manuel I.; Salinas, Dino G. – Biochemistry and Molecular Biology Education, 2021
An educational activity is proposed that uses software for proteomic analysis and databases available for free on the Internet to estimate the structure and function of a hypothetical protein from its coding nucleotide sequence. This bioinformatics activity is recommended for integrated introductory courses that address the structure function…

Mungan, Carl E. – Physics Teacher, 2021
Races between moving objects are an engaging way to teach dynamics to introductory physics students. One standard example consists in racing hollow and solid cylinders as they roll down an inclined plane. Another striking demonstration is a race between two marbles on side-by-side tracks that start and end together, but with one track taking a…

McCoy, Bradley K. – Physics Teacher, 2021
In a typical first physics class, homework consists of problems in which numerical values for physical quantities are given and the desired answer is a number with appropriate units. In contrast, most calculations in upper-division undergraduate physics are entirely symbolic. Despite the need to learn symbolic manipulation, students are often…

Mankiw, N. Gregory – Journal of Economic Education, 2022
The author has long thought that the role of instructors in the introductory economics classroom is to serve as ambassadors for the economic profession. They are there not to present their own views of economics. They should, instead, transcend their idiosyncrasies and represent the broad consensus of professional economists. The job of the…
