This article describes a simple and inexpensive "shock and awe" classroom demonstration for understanding the importance of carbon dioxide (CO[subscript 2]) in acid-base regulation. Before class, a solution was prepared by adding sodium bicarbonate and universal indicator solution to a sample of distilled water contained in a standard…

Ciphers based on rotor machines were the state-of-the-art in the mid-1900s, with arguably the most famous being the German Enigma. We have found that students have great interest in the Enigma and its cryptanalysis, so we created our own rotor cipher that is simulated with shifting tables and can be cryptanalyzed. Ours and the historic rotor…

With a certain tone of concern, Suzanne Graham's article presents readers with a series of perceived problems related to current methods of teaching listening skills in the second language classroom. The general explanation behind these observations is the author's perception that language teachers' practices do not 'reflect current thinking from…

This case provides an opportunity for classroom discussion of ethical issues addressed by computing technologists and the Association of Computing Machinery (ACM) Code of Ethics as the authors describe a recent lawsuit brought against Sutter Health. Security issues, data breaches and compliance with industry privacy rules are common concerns for…

This paper gives four examples of the use of short speculative fiction for teaching different aspects of information privacy. Information privacy is multi-faceted; as an area of study it intersects with a number of fields. A non-exhaustive list could include: law, information systems, decision science, marketing, management, philosophy,…

This study analysed the instructors' teaching presence of three courses conducted by an instructor to explore the effects of the instructors' online teaching presence on students' interactions and collaborative knowledge constructions. Content analysis, social network analysis, and lag sequential analysis were used to explore the mechanism of…

The current work builds on research demonstrating the effectiveness of Productive Failure (PF) for learning. While the effectiveness of PF has been demonstrated for STEM learning, it has not yet been investigated whether PF is also beneficial for learning in non-STEM domains. Given this need to test PF for learning in domains other than…

Although recent scholarship on the biblical studies survey course has sought to bring in a wide array of new methods and ways to incorporate the Bible into the broader liberal arts curriculum, a dearth of tactics for employing biblical manuscripts in the classroom remains. This article details one experience crafting two class sessions for an…

This chapter describes four concepts from the learning sciences that provide research-based recommendations for instructional practice. The authors explore how these teaching approaches manifest in different institutional, disciplinary, and course contexts.

Researchers have documented the impact of rater effects, or raters' tendencies to give different ratings than would be expected given examinee achievement levels, in performance assessments. However, the degree to which rater effects influence person fit, or the reasonableness of test-takers' achievement estimates given their response patterns,…

This article shares three main lessons the author learned from her correspondence with Vivian Gussin Paley. Early on, the author wrote Mrs. Paley about how she discovered the meaning of story acting for visually impaired children. The act of sharing her thoughts with Mrs. Paley showed her the power of writing to promote thinking. Equally important…

Difficulties in learning (and thus teaching) statistical inference are well reported in the literature. We argue the problem emanates not only from the way in which statistical inference is taught but also from what exactly is taught as statistical inference. What makes statistical inference difficult to understand is that it contains two logics…

As a pedagogical approach, process oriented guided inquiry learning (POGIL) allows students to socially construct knowledge through iterative cycles that include three steps: exploring a model, inventing a concept, and applying the resulting ideas. A growing body of research indicates that relative to lecture-based approaches, POGIL supports…

Today, talking about educational planning generates a certain vital importance for the achievement of the goals and objectives previously established, as well as the definition of the steps and means necessary to carry out this process. However, we cannot talk about planning without addressing the assessment process as an essential element to…

Researchers are often reluctant to rely on classification rates because a model with favorable classification rates but poor separation may not replicate well. In comparison, entropy captures information about borderline cases unlikely to generalize to the population. In logistic regression, the correctness of predicted group membership is known,…
