In this paper, we present a physical modeling activity whose objective is to allow students to determine the differences between a disk and a sphere using pure scientific criteria. Thereunto, we reproduce the Sun-Earth-Moon system with low-cost materials and compare the illumination effects on the Moon considering two possible shapes for it (a…

The authors adapted a lab-in-the-field experiment emulating the dynamic extraction of a fishery to create a Web-based classroom experiment. The game includes a multi-player version analogous to an open-access problem and a single-player version analogous to the social planner problem. This game is helpful in introductory microeconomics courses to…

Peter Dunn and Margaret Marshman present the second of their data files articles in which they discuss the statistical investigation cycle which describes the whole process of conducting a statistical research study. [For "The Data Files: A Series of Articles to Support Mathematics Teachers to Teach Statistics," see EJ1259108.]

As China is playing an active role in the World's politics, economy, and cultural circles, being able to communicate in English has become one of the basic life and work skills and a key for global access and integration. High mobile technology penetration, together with the proliferation of mobile learning applications, have made it possible for…

We designed a hands-on laboratory exercise to demonstrate why injecting an aqueous polymer solution into an oil reservoir (commonly known as "polymer flooding") enhances oil production. Students are split into three groups of two to three. Each group is assigned to a packed Hele-Shaw cell pre-saturated with oil, our laboratory model of…

To compare the efficacy of two interventions to promote colorectal cancer screening participation and forward stage movement of colorectal cancer screening adoption among first-degree relatives of individuals diagnosed with adenomatous polyps. One hundred fifty-eight first-degree relatives of individuals diagnosed with adenomatous polyps were…

This paper shares a practice of encouraging critical analysis in science students by comparing mobile applications and peripherals to traditional tools to record physiological variables such as heart rate and blood pressure. A progressive series of case studies is described with learning outcomes mapped to the benchmark statement for Bioscience…

There is no doubt that Computer Mediated Communication (CMC) and mobile mediated communication are linked as technology continues to transform the way we communicate with each other. Campbell (2019) analyzed how mobile communication evolved into portable devices to form a complete system of mobile media, reshaping the fabric of our social lives…

The purpose of this article is to describe the characteristics and effectiveness of a telepractice speech-language therapy program for school-age children. Outcome data related to the caseload, type and amount of intervention, and student progress from a school-based telepractice therapy program were compared with the K-12 Schools National…

For the majority of those living in developing countries (especially in the rural areas) sharing may be the only means of obtaining access to IT. Oddly, however, no-one has viewed "IT for development" specifically from this point of view for the Internet, computers and mobile phones. A good beginning, it seems to me, is to make an analytical…

In this article, the authors attempt to answer the following questions: How do we understand role-play? How are role-play and identity linked? What are the purposes, benefits and challenges of role-play as a teaching tool? What are the roles of students and teachers in role-play? What does role-play add to telephone tutorials and online…

Conceptually, e-mail is not a whole lot different from regular postal mail ("snail mail"), except that it is much faster. E-mail requires three things: (1) a personal computer; (2) a telephone or communication line; and (3) an Internet provider (e-mail service account). This article provides details on how it works--plus some research activities…

This article describes two lessons within the authors' education module entitled, Ecological Networks, that successfully teaches introductory systems content to middle and high school students. To catch students' attention when teaching these new concepts, they decided to use a network that was familiar and fun for students--a cell-phone…

Profiles the major wireless data communications (WDC) systems, provides an overview of how they work, and compares their communication features. Topics addressed include the market for wireless data; applications for WDC; wireless online searching; cellular data communication; packet radio; digital cellular; criteria for evaluating WDC systems;…

Compares state telecommunications regulatory policies and their potential impacts on the development of the physical infrastructure needed to support an information superhighway. Topics include federal telecommunications regulations, federal preemption of state regulations, and economic impacts of the development of the National Information…
