Contribution: Prior studies indicate that students experimenting with characterization of optical planar waveguides use expensive ready-made prism couplers without clear understanding about construction of the entire optical measurement system. This paper presents a cost-effective modified bright-mode prism coupler that helps students learn…

Some policies try to maximize net benefits by targeting different individuals to participate. This is difficult when costs and benefits of participation vary independently, such as in land conservation. The authors share a classroom game that explores cases in which minimizing costs may not maximize benefits and vice versa. The game is a…

For the author, the concept of wound care has always been a challenging topic to demonstrate. How to teach the concept without having a student in need of wound care or without having to spend money to buy another simulation manikin/model? The author has recently created a simulation to demonstrate and practice the cleaning, closing, and dressing…

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…

Suggests that most schools can not currently afford to make an investment in interactive video technology, and points out problems with availability of materials. (ARH)

Presents a method for quantifying the costs and benefits of research to teach undergraduate psychology students research ethics and the statistical concepts of central tendency and variability. Outlines how students rate the costs and benefits of well-known psychology experiments, and learn how to analyze and interpret their findings. (DSK)

Designed to culminate an ornamental horticulture class, this teaching guide provides information needed for the year-round operation of a school and/or commercial greenhouse. Three units are presented: production schedules, determining harvest time, and cost analysis. Each unit lists major teaching points, learning activities, and reference…

Presents a diagrammatic proof for classroom use to demonstrate the quasi-convexity of the indirect utility function. Includes a variation of the price indifference curve. Suggests an exercise in which the student is asked to show that the tangency condition is a restatement of Roy's identity. (DK)

Cost control is the subject of this eight-lesson, three-test food service training manual. Lesson 1 deals with financial accountability and includes 17 handouts, ranging from sample balance to quarterly report sheets. Lesson 2 focuses on budgeting principles, and lesson 3 on labor controls. Professional purchasing, receiving, and inventorying…

Presents an alternative experimental arrangement that results in a considerable cost savings by reducing the number of sensors and other apparati required while giving excellent quantitative results for comparison with theory. (Author/CCM)

Presented are suggestions for instructional content for a teaching unit or individualized learning package designed to develop the knowledge all consumers need in order to obtain the safest, fastest, and lowest-cost mail service. (LRA)

Includes two activities: (1) a skit to review variations of the trigonometric functions, and (2) a geometry problem about maximizing costs that exposes students to a variety of different solution strategies and makes the material more meaningful. (MKR)

The experiences of a number of institutions using a variety of approaches show that distance education by television can be both instructionally effective and cost effective. Careful attention to five steps in course development (planning, preparation, rehearsal, presentation, and review) can help colleges save time and avoid pitfalls. (MSE)

The manufacturing process used to produce printbands for International Business Machines, Inc. involves a photolithographic process in which the stainless steel panels are chemically machined using strong ferric chloride etching solution containing hydrochloric acid. The waste material that results from this chemical reaction is a solution…

Information about the world and how it works is often hard to locate and difficult to understand. The objectives and activities in this teaching guide were developed to complement the "World Military and Social Expenditures" (WMSE) report in the study of global issues in secondary school classrooms. The report contains well-documented and…
