In this article, physical quantities related to the motion of a parachute system in the framework of Newton's law of mechanics guide an informal approach to the mathematical concept of function. Furthermore, a graphical simulator that enables visualization of the fall of object-parachutes system is presented. The article is aimed at students and…

Computer-assisted language learning (CALL) has greatly enhanced the realm of online social interaction and behavior. In language classrooms, it allows the opportunity for students to enhance their learning experiences. "Exploration of Textual Interactions in CALL Learning Communities: Emerging Research and Opportunities" is an ideal…

We present background and an activity meant to show both instructors and students that mere button pushing with technology is insufficient for success, but that additional thought and preparation will permit the technology to serve as an excellent tool in the understanding and learning of mathematics. (Contains 5 figures.)

Visualization of mathematical relationships enables students to formulate conjectures as well as to search for mathematical arguments to support these conjectures. In this project students are asked to discover the sufficient and necessary condition so that two circles form the circumscribed and inscribed circle of a triangle and investigate how…

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…

This article describes a vision of student use of dynamically connected representations as they investigate mathematical ideas. Although this article is intended to generate discussion about the potential of dynamically connected representations, we situate the discussion within actual descriptions of its use with students in a newly designed…

Obesity has been recognized as a worldwide public health problem. It significantly increases the chances of developing several diseases, including Type II diabetes. The roles of insulin and leptin in obesity involve reactions that can be better understood when they are presented step by step. The aim of this work was to design software with data…

Learner corpora, electronic collections of spoken or written data from foreign language learners, offer unparalleled access to many hitherto uncovered aspects of learner language, particularly in their error-tagged format. This article aims to demonstrate the role that the learner corpus can play in CALL, particularly when used in conjunction with…

This two-part series describes the structure of the stoichiometry course at North Carolina State University. The course had a variety of learning objectives, and several nontraditional pedagogies were used in the course delivery. The first paper outlined the course structure and policies, the preparation given to the teaching assistants who played…

This document contains a slightly-revised syllabus for a Virtual Reality course taught in spring 1994. The syllabus begins with an introduction which contains information on the software used in the course and examples of schools that have introduced virtual reality technology in the curriculum. The remainder of the document is composed of the…

The independent Waterford School in Provo, Utah, opened in September 1981, with the goal of providing, through technology, all children with an excellent education. Additionally, it intended to demonstrate how computers could best be used as part of educational delivery. School administrators have found that computerized instruction is improved by…

An instructional method using flow-chart symbols to make mathematical abstractions more concrete was implemented for a year in a technical mathematics course. Students received instruction in computer applications and programming in the BASIC language in order to increase motivation and firm the mathematical skills and problem-solving approaches…

Describes two expert programs including "One-Row NIM" and "TIC-TAC-TOE." Provides two programs written with BASIC and the explanations of the program. (YP)

The first document in this set is a final report titled "Preparation for the Mathematics GED Test: A Computer Based Program," which describes a project to develop a General Educational Development (GED) mathematics preparation program for the adult learner at the 9-12 grade level. The other two documents are a teacher's guide and a…

Presented are the background theory, program procedures, output display, and applications for this program which is designed to calculate the slip vector and the stress to normal stress ratio on an arbitrarily oriented fault plane. Program availability is discussed. Twelve references are listed. (CW)
