In this article, a course on high-frequency wireless communications systems is presented. With the 145-MHz baseband subsystem available from a prerequisite course, the present course emphasizes the design and implementation of the 2.45-GHz front-end subsystem as well as system integration issues. In this curriculum, the 2.45-GHz front-end…

This study develops a Multiprog virtual laboratory for a mechatronics education designed to teach how to programme a programmable logic controller (PLC). The study was carried out with 34 students in the Department of Industry Education and Technology at National Changhua University of Education in Taiwan. In total, 17 students were assigned to…

This paper addresses the difficulties experienced by first-grade students studying rigid body motion at Sofia University. Most quantities describing the rigid body are in relations that the students find hard to visualize and understand. They also lose the notion of cause-result relations between vector quantities, such as the relation between…

In the field of automation technology, research and development for industrial applications has increased rapidly in recent years. Therefore, industrial automation and control education is a very important element of the industrialization process in developing countries, such as Turkey, which needs to keep abreast for the latest developments in…

The development of critical thinking is crucial in professional education to augment the capabilities of pre-professional students. One method for enhancing critical thinking is participation in role-playing simulation-based scenarios where students work together to resolve a potentially real situation. In this study, undergraduate nursing…

Imposed time limits on computer adaptive tests (CATs) can result in examinees having difficulty completing all items, thus compromising the validity and reliability of ability estimates. In this study, the effects of speededness were explored in a simulated CAT environment by varying examinee response patterns to end-of-test items. Expectedly,…

This study examines the interacting roles of implicational markedness and frequency from the joint perspectives of formal linguistic theory, phonological acquisition and computational modeling. The hypothesis that child grammars are rankings of universal constraints, as in Optimality Theory (Prince & Smolensky, 1993/2004), that learning involves a…

This article describes workshops for high school physics teachers in Uganda on inquiry-based teaching and PhET simulations. I hope it increases awareness of the conditions teachers face in developing countries and inspires others to give similar workshops. This work demonstrates what is possible with some concerted, but not extraordinary, effort.

Empirical evidence demonstrating that sentence meaning is rapidly reconciled with the visual environment has been broadly construed as supporting the seamless interaction of visual and linguistic representations during situated comprehension. Based on recent behavioral and neuroscientific findings, however, we argue for the more deeply rooted…

Berge's Instructor's Roles Model categorized the instructor's roles as pedagogical, social, managerial, and technical. Developed more than a decade ago, this model described changing roles for instructors as they transitioned from in-person classrooms to teaching online. Today, as virtual worlds emerge and are being used as educational platforms,…

Human behavior representation (HBR) models simulate human behaviors and responses. The Joint Crowd Federate [TM] cognitive model developed by the Virginia Modeling, Analysis, and Simulation Center (VMASC) and licensed by WernerAnderson, Inc., models the cognitive behavior of crowds to provide credible crowd behavior in support of military…

The use of visual occlusion as a cue to altitude maintenance in low-altitude flight (LAF) was investigated. The extent to which the ground surface is occluded by 3-D objects varies with altitude and depends on the height, radius, and density of the objects. Participants attempted to maintain a constant altitude during simulated flight over an…

Missing data are a common problem in a variety of measurement settings, including responses to items on both cognitive and affective assessments. Researchers have shown that such missing data may create problems in the estimation of item difficulty parameters in the Item Response Theory (IRT) context, particularly if they are ignored. At the same…

Narrative is said to be an important way that humans come to understand their world as it is and as it can be. If this is true, then literary narrative must possess significant value since it has historically and cross-culturally received much attention and appreciation. This study gives an account of the cognitive value of literature in terms of…

The authors propose the idea of threaded cognition, an integrated theory of concurrent multitasking--that is, performing 2 or more tasks at once. Threaded cognition posits that streams of thought can be represented as threads of processing coordinated by a serial procedural resource and executed across other available resources (e.g., perceptual…
