This paper presents five designs (three one-group and two two-group) which can be effectively employed to study computer-based methods in non-laboratory settings, including actual classroom implementation, where a non-treatment control design may not be feasible. These designs are sequential analysis, value-added analysis, non-equivalent dependent…

Presents five research designs--sequential analysis, value added analysis, nonequivalent dependent variables, regression discontinuity, cohort design--for studying computer-based teaching methods when a randomized two-group design is impractical; provides examples of studies employing these designs and decision flowchart; and discusses selection…

Explains how optimal control problems can be solved with a spreadsheet, such as Microsoft Excel. Suggests the method can be used by students, teachers, and researchers as a tool to find numerical solutions for optimal control problems. Provides several examples that range from simple to advanced. (JEH)

Identifies a Web site providing information about stock market simulations for high school economics courses. Divides the information into two tables: (1) the structure of online stock market games; and (2) the determination of portfolio values of online stock market games. States that changes and updates are available at Web sites. (JEH)

Discusses how to examine and evaluate claims of improved academic performance in advertisements for computer-assisted instruction. Highlights include the proper use of comparison groups; types of statistical analyses; the Hawthorne effect; the interpretation of scores; interpreting graphic presentations; tests of significance; and cost…

The usefulness of microcomputers for teaching social science research methods has been the subject of numerous articles. This article describes how microcomputers can be used to teach public policy content, particularly topics involving controversial issues. The discussion is organized into four sections. Section 1, "Four Important Elements,"…
