Regression discontinuity (RD) analysis is a rigorous nonexperimental approach that can be used to estimate program impacts in situations in which candidates are selected for treatment based on whether their value for a numeric rating exceeds a designated threshold or cut-point. Over the last two decades, the regression discontinuity approach has…

Problem-­solving assessment is an essential component of multi-­tiered systems of support such as response to intervention (RTI) and positive behavioral interventions and supports (PBIS). This authoritative work provides a complete guide to implementing a wide range of problem­-solving assessment methods, including: (1) functional behavioral…

Presents 10 rules for effectively using graphs as performance improvement tools. Pie charts, bar graphs, cumulative graphs, and scatter diagrams are discussed, and a case study illustrates how setting goals and using graphs for feedback on performance can be effective. (LRW)

Presents a profile of Ann Wagner, a mechanical engineer at the Goddard Space Flight Center in Maryland, and her job responsibilities there. Also includes a brief history of mechanical engineering as well as a sample graph and data activity sheet with answers. (AIM)

A method for sketching functions and finding slopes and roots rising synthetic division is illustrated. (MK)

Although computer graphics professionals usually consider only technical graphic design issues, recent improvements may make the only limiting design factors the user's purpose, imagination, style, and taste rather than computer hardware or software technology. Computer graphics designers can be helped to avoid pitfalls by understanding the visual…

This monograph is a test of graphing and graph interpretation skills which assesses performance on all the skills of graphing which are contained in the AAAS program, Science - A Process Approach. The testing includes construction of bar graphs, interpreting information on graphs, the use of the Cartesian coordinate system, making predictions from…

A diagrammatic approach to invariants of knots is the focus. Connections with graph theory, physics, and other topics are included, along with an explanation of how proofs of some old conjectures about alternating knots emerge from this work. (MNS)

This guide to the discovery, analysis, production, communication, and use of statistical information through graphic forms produced by a computer is designed to enable researchers to conduct their analyses and report research results more effectively. It is designed both for individuals with little knowledge about the use of statistical graphs or…

The focus is on how line graphs can be used to approximate solutions to rate problems and to suggest equations that offer exact algebraic solutions to the problem. Four problems requiring progressively greater graphing sophistication are presented plus four exercises. (MNS)

Material in this document has been prepared to assist teachers using the Sullivan Programmed Reading Series and to make the program more applicable to the needs of children with exceptional educational needs. The format of the series provides activity orientation (response, reward, repetition), gradual progression from easy to difficult words,…

Included in this department are brief articles on generating primitive Pythagorean triples with a computer program; using pictographs or pictures on graph paper to teach general graphing concepts; a method for factoring trinomials; and summing the harmonic series. (MNS)

Four problems are presented and solutions using a calculator are illustrated. (MK)

Describes the design and operation of four software packages, or macros, written in the programing language of Microsoft's EXCEL for use on the Macintosh computer for data manipulation and presentation used in educational research. Reordering tabulated data, reversing the scoring of tabulated data, and creating tables and graphs are explained.…

Discusses the use and interpretation of multiple regression analysis with computer programs and presents a flow chart of the process. A general explanation of the flow chart is provided, followed by an example showing the development of a linear equation which could be used in estimating manufacturing overhead cost. (Author/LRW)
