This booklet is designed to assist those responsible for conducting educational evaluations. The work contains a collection of recently developed technical procedures relevant to educational evaluation and to describe them in a straightforward manner. The guidelines are organized into three sections: 1) Objectives; 2) Measurement; and 3) Data Collection and Analysis. In the objectives section, seven guidelines are presented which deal with such matters as how objectives should be specified so that they will be of most utility to the evaluator. The measurement section contains five guidelines treating such problems as how the evaluator should devise measures which satisfactorily assess whether an objective has been achieved. The section dealing with data collection and analysis includes eight guidelines dealing with the types of designs evaluators should employ for various situations and how to treat the data secured via these designs. A summary of all guidelines is presented at the close of these three sections. A final section, Playing by the Rules, provides a fictitious example of an educational evaluator who conducts his/her work consonant with the guidelines. A set of selected references, organized around the major sections of the guidebook concludes the volume. (FDI)
