In this paper, I analyze the impact of culture and metaphor on cryptology education. I will compare and contrast the historically grounded metaphors of cryptology-is-warfare and encryption-is-security to a set of counter-metaphors: cryptology-is-privacy and encryption-is-communication. Using this explicit understanding of conceptual metaphor, I…

In the precalculus curriculum, logistic growth generally appears in either a discrete or continuous setting. These actually feature distinct versions of logistic growth, and textbooks rarely provide exposure to both. In this paper, we show how each approach can be improved by incorporating an aspect of the other, based on a little known synthesis…

Based on work conducted through the Instructional Moves project at Harvard University, "Instructional Moves for Powerful Teaching in Higher Education" outlines the many ways in which good college and graduate school teaching is rooted in deliberate pedagogical choices that support active learning. Jeremy T. Murphy and Meira Levinson…

Courses: Rhetorical Criticism, Communication Theory, Media Criticism. Objectives: This activity uses a diagram to help students visualize Kenneth Burke's theory of dramatism. Specifically, through an analysis of the film Hell or High Water, students learn to identify each stage of the guilt-purification-redemption cycle and gain insight into its…

The lateral flow immunoassay (LFIA) is a simple and cost-effective rapid diagnostic test designed for the on-site detection of disease biomarkers. In the context of introducing this technique to undergraduate biotechnology students, we propose a comprehensive 5 h laboratory experiment. This experiment covers various aspects, including the…

Creativity plays an important role in mathematics, but it can be overlooked in undergraduate courses. This article describes three ways an existing first-year math seminar was modified to increase its focus on creativity: introducing readings and discussions related to creativity, drawing connections to creativity in other disciplines, and adding…

A significant activity in the business analytics process is enrichment, which deals with acquiring and combining data from external sources. While different strategies for enrichment are possible, it can be accomplished more efficiently through automation using Python scripts. Since business students may not be immersed in technology skills and…

A set of inexpensive and pedagogically rich experiments focusing on S[subscript N]1, E1, and E2 reactions have been updated to include modern computational and spectroscopic analyses. The S[subscript N]1 experiment involves treatment of "tert"-amyl alcohol with hydrochloric acid to generate the corresponding alkyl chloride, which is used…

This article aims to explore the experiences of science instructors who are active participants in the design and enactment of an interdisciplinary science course with student-centered pedagogy in a large-enrollment class. The data were collected through interviews with instructors and analyzed using the inductive thematic approach. Results show…

This study focuses on developing specific vocabulary learning strategies to assist the receptive knowledge of English for Specific Purposes (ESP). It aims to provide a practical framework for teaching technical vocabulary. The study introduced the Multimedia Strategic Vocabulary Learning (MSVL) model and investigated its effects on teaching…

The use of operant chambers for research and teaching in behavior analysis is in decline due to the expense, maintenance, and ethical considerations of such complex mechanical apparati (Venneman and Knowles in Teach Psychol 32(1):66-68, 2005. https://bibliotheek.ehb.be:2102/10.1207/s15328023top3201_13). Other technologies for testing and demonstrating behavioral…

The VSEPR model has well-established limitations in its ability to represent accurate molecular and electronic geometries of simple molecules, which can create a significant need for students to relearn structure and bonding concepts in organic chemistry. We present an alternate method for describing molecular geometries and electronic structures…

In the world of higher education, one of the struggles instructors face in the classroom is engaging students in the material. A second discussion in higher education pedagogy is how to weigh content versus activity in the science classroom. How should college teaching be set up when students now have every fact ever found at their fingertips on a…

The real time PCR (qPCR) method provides a powerful method to assess levels of particular species of DNA. When combined with reverse transcription (RT-qPCR) it is the predominate technique to measure expression of gene transcripts. While this approach is very powerful, particular care must be taken in the design of the primers to facilitate…

Two of the most fundamental skills that students acquire in introductory undergraduate physics laboratory courses are how to accurately plot data and interpret the physical meaning of linear graphs. We redesigned our graphing skills lab with an open-ended approach designed to promote inquiry in graphical analysis and to address specific areas of…
