Topological data analysis (TDA) is a collection of powerful tools that can quantify shape and structure in data in order to answer questions from the data's domain. This is done by representing some aspect of the structure of the data in a simplified topological signature. In this article, we introduce two of the most commonly used topological…

Reviews evaluation standards that are used to assess the quality of projected graphical displays, and discusses their use in evaluating graphs created with computer graphing programs. Design standards for projected graphs are explained, and examples of three types of graphs are shown. (four references) (LRW)

Offers graphical proof of the proposition that the dynamically efficient allocation of a depletable, nonrenewable resource allows higher net benefits to users in both time periods than any other allocation. States that in this proof the result is more general and does not require the numerical specification of other previous models. (JEH)

While most microeconomics curriculums contain no reference to the use of microcomputers, spreadsheet packages adapt well to microeconomics courses. This presentation examines the following topics in the context of a microeconomics course: (1) The Microcomputer Spreadsheet Package--LOTUS; (2) The Spreadsheet Anatomy--cells, commands, menus; (3)…

Discusses three phases of instructional design (ID)--definition of instructional parameters, analysis and synthesis of instructional alternatives, and implementation of instructional plan--and presents a 15-step ID model. Included for each step are a descriptive name, boxed example, and rationale and (as applicable) current state of technology for…

This collection of activities demonstrates how the study of elementary mathematics can be extended beyond the school and involve teachers and students in investigative, problem-based experiences. The activities include topics in geometry, concept of number, algebra, measurement, graphing, statistics, and probability, and are organized into five…

The resource manual was developed by a staff development project that trained both paid staff and volunteer tutors to integrate CASAS (Comprehensive Adult Student Assessment System) as an assessment and curriculum tool. It is designed to assist tutors in linking task and skill competencies. The manual begins with an overview of assessment and…

A 1982 revision of a 1972 publication, this handbook aims to provide a process that school boards can use to evaluate management performance and set administrator salary and compensation schedules. Following a brief introduction, the first two sections note the problem of public criticism of school administrator salaries and review several…

This document gives instructions on how to use a Macintosh computer to create printed materials for mathematics. A Macintosh computer, Microsoft Word, and objected-oriented (Draw-type) art program, and a function-graphing program are capable of producing high quality printed instructional materials for mathematics. Word 5.1 has an equation editor…
