Computer adaptive testing (CAT) is an increasingly common mode of test administration offering improved test security, better measurement precision, and the potential for shorter testing experiences. This article presents a new item selection algorithm based on a generalized objective function to support multiple types of testing conditions and…

Problems associated with time-cost trade-offs in project networks, which are commonly referred to as crashing problems, date back nearly 60 years. Many prominent management science textbooks provide a traditional linear programming (LP) formulation for a classic project crashing problem, in which the time-cost trade-off for each activity is…

Asynchronous video-based educational resources allow for increased course material engagement. In today's climate, educators are encouraged to create videos for online instruction but are typically given limited production guidance. Few formal resources exist to guide educators for high-quality video production in a non-studio setting. This…

Excel spreadsheets are used as an excellent tool in physics laboratory experiments related to wave optics. This paper presents a simple way to simulate diffraction of waves through a slit using Excel spreadsheets without any tedious programming. These simulations are used to visualize the effect of variation of different parameters such as number…

This paper describes the functionality, scalability, and cost of implementing and maintaining a suite of open source technologies, which have supported hundreds of thousands of learners in the past year, on an information technology infrastructure budget of less than US$10,000 per year. In addition, it reviews pedagogical opportunities offered by…

Introductory chemistry students encounter the concept of hybrid orbitals as a transition from atomic orbitals to molecular bonding. The principal purpose of learning hybridization in the undergraduate curriculum is to impart an understanding of the origins of molecular bonding and geometry. Physical models of both individual hybrid orbitals and…

Modern high school career and technical education (CTE) programs are often referred to as "high-quality CTE," and they are designed to help students build career skills and earn credentials through sequenced coursework, postsecondary credit acquisition, and exposure to relevant work-based learning experiences. These kinds of programs,…

Within the past few years there has been an increasing emphasis on making computer science (CS) more accessible for all K-12 students. In 2013 there were 12 states that allowed CS courses to count towards high school graduation, and in 2018 that number had grown to 35 states plus the District of Columbia (Code.org, 2018). Due to the increasing…

The New Haven Local Section of the American Chemical Society held a virtual version of its annual Student Research Symposium prompted by the COVID-19 pandemic. A combination of YouTube, Google Drive, Open Broadcaster Software, and Zoom was utilized to hold the symposium which included juried oral and poster presentations. While our aim was to…

MIRELE is an interactive tabletop for situated domain learning that helps students learn names of the physical objects and their relationships by projecting the names, relationships, and additional information onto the real objects. It is built based on a camera-projector system and offers a domain-independent fast authoring system. Using the…

This paper presents a method to design high-quality 3D equipment for virtual laboratories. A virtual control laboratory is designed on large-scale educational purpose with merits of saving expenses for universities and can provide more opportunities for students. The proposed laboratory with more than 30 virtual instruments aims at offering…

Human Machine Learning Symbiosis is a cooperative system where both the human learner and the machine learner learn from each other to create an effective and efficient learning environment adapted to the needs of the human learner. Such a system can be used in online learning modules so that the modules adapt to each learner's learning state both…

Recently devices such as the optical mouse of a computer, webcams, Wii remote, and digital cameras have been used to record and analyze different physical phenomena quantitatively. Devices like tablets and smartphones are also becoming popular. Different scientific applications available at Google Play (Android devices) or the App Store (iOS…

Purpose: Mobile data traffic globally is increasing rapidly in both enterprise and consumer segments. The purpose of this paper is to identify a new network architecture and opportunity that support ubiquitous mobile work for higher-education institutions. Design/methodology/approach: It reviews existing literature and enabling technologies and…

This educational case, in two parts (A and B), requires students to assume the role of a business consultant and to use Excel to develop a profit-planning or a cost-volume-profit (CVP) model for a package-delivery company opportunity currently being evaluated by a client. The name of the proposed business is Pack-and-Go, which would provide an…
