Here we demonstrate an inexpensive and straightforward electronic circuit that can be used to generate data in the form of counts, with the same statistical properties as those found in gamma-ray counting experiments. The circuit holds an avalanche Zener diode just below its Zener voltage, which allows for thermal electrons to traverse the in the…

Although they commonly are associated with recreation, summer camps for children can be seen as educational arenas that both supplement and challenge school education. Summer camps provide education in a broad sense of "bildung." The article aims at describing what is experienced in summer camps and proposes various theoretical frames…

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…

Computational chemistry modeling activities that took place as part of a course in physical chemistry are described. The main software tools used by the students were Avogadro and ORCA, which are freely available on the Internet for academic use. Avogadro is molecular visualization software, which can be used not only to prepare input files for a…

In this work, different alternatives for locating the optimal feed stage in a distillation column as well as the effect of the feed temperature are studied, by solving a classroom problem. The results obtained permit us to select the best way to optimize the feed stage location as well as to detect what thermal feed phase conditions should be…

Philosophers of education as well as philosophers, sociologists and other theoreticians are searching for new models and interpretations of teaching, using new concepts, "transversality" being one of them. Some treat the new ways based on transversal competence as an augmentation of neoliberal power and its influence at school, some, on…

This study focuses on connections between linear functions and their graphs that were made by tertiary remedial algebra students. In particular, we describe students' work on a Task designed to examine the connection between points on a graph and the equation of a line. The data consist of 63 responses to a written questionnaire and individual…

Proteopedia (proteopedia.org) is an open resource to explore the structure--function relationship of proteins and other biomolecules. This guide provides practical advice on how to incorporate Proteopedia into teaching the structure and function of proteins and other biomolecules. For 11 activities, we discuss desired outcomes, setting…

In this experiment, students explore the synthesis and physical property characterization of the magnetic material strontium hexaferrite (SrFe[subscript 12]O[subscript 19]). SrFe[subscript 12]O[subscript 19] crystallites are prepared by a simple but fascinating sol-gel autocombustion synthesis. The prepared powder is compacted into pellets and…

This study explored the influence of different take-off thresholds on the reliability and magnitude of countermovement jump (CMJ) performance variables. Twenty-three men were tested on two separate sessions. CMJ performance variables were obtained against three external loads (0.5-30-60 kg) using three take-off thresholds: 10 N (arbitrary value of…

The case of "Pellham v. Let's Go Tubing, Inc." (2017) is the result of the plaintiff striking a fallen log in the river after he fell off an inner tube he had rented from the defendants. The plaintiff sustained a ruptured eardrum, lower-disk problems in his back, a radiating foot pain, and eventually a neck fusion. The plaintiff alleged…

The purpose of this article is to introduce and provide suggestions for the organization of a university powerlifting physical activity course in which the sport education model was implemented. The powerlifting course took place over a 15-week period and involved students carrying out various roles, taking part in team workouts and competitions,…

Courses: Public Relations, Public Administration, Crisis Communication, and Crisis Management. Objective: Students explore crisis communication in a public setting, where public leaders are supposed to communicate the impact of a crisis to citizens, the media, and other stakeholders.

The authors investigated improvisational theater and the possibilities that it presents for reconsidering reading pedagogy, with a focus on discussions of reading. The authors conducted empirical, qualitative studies of improvisational practice and instruction and analyzed improv through the construct of worlding. In this article, the authors…

The authors set out to develop a series of mathematical games that could be played 'openhanded' over zoom using only a virtual deck of cards (deck.of.cards). This article briefly describes three games they have developed that other teachers might find valuable, whether for use in a remote learning environment or back in the classroom. Each game…
