Education has been progressing at a rapid pace ever since educators have been able to harness the power of mobile technology. Open-access learning techniques provide more students with the opportunity to engage in educational opportunities that may have been previously restricted. "Empowering Learners with Mobile Open-Access Learning…

Natural selection and other components of evolutionary theory are known to be particularly challenging concepts for students to understand. To help illustrate these concepts, we developed a simulation model of microevolutionary processes. The model features all the components of Hardy-Weinberg theory, with population size, selection, gene flow,…

Today's students grow up in a technological milieu of hand-held computers with high storage capacities, internet access, and the ability to shoot high definition photographs and video. As such, they are empowered to construct representations of the past virtually "on the run." In this article, the authors investigated the historical "and"…

Freezer burn is a common problem that significantly affects the color, texture, and flavor of frozen foods. Food science students should be able to clearly explain the causes and consequences of freezer burn. However, it is difficult to find a modern, detailed, accurate, yet concise, explanation of the mechanism and factors influencing the rate of…

Objectives: After this lesson, students will be able to: (1) list the five stages of materials production, (2) report key facts related to the materials economy, (3) identify sustainable solutions that positively impact the environment, and (4) recognize how the environment affects health. Target Audience: This activity is designed for students in…

Computer advances now let researchers quickly search through DNA sequences to find gene variations that could lead to disease, simulate how flu might spread through one's school, and design three-dimensional animations of molecules that rival any video game. By teaming computers and biology, scientists can answer new and old questions that could…

Animations of the particulate level of matter are widely available for use in chemistry classes and are often the primary means of representing molecular behavior. These animations may also be viewed by individual students using textbook Web sites, although without reinforcement or feedback. It is not known to what extent the material in these…

Guided by the principles of learner-centered teaching methodology, a Second Life project is designed to engage students in active learning of virtual commerce through hands-on experiences and teamwork in a virtual environment. More importantly, an assessment framework is proposed to evaluate the learning objectives and learning process of the…

This reinforcement activity has been used by students from the elementary school level to the graduate school level who possess intermediate level ability in programming Logo. The activity, which consists of writing Logo programs that animate an object, can have several positive effects as it: (1) helps develop problem-solving skills; (2)…

Animation is being used extensively for instructional purposes; however, it has not been found to be effective on measures of higher order learning (concepts, rules, procedures) within the knowledge acquisition and knowledge integration domains. The purpose of this study was to examine the instructional effectiveness of two visual scaffolding…
