A number of potential threats to internal validity in true experiments are discussed. Programmatic research efforts proceeding from established correlational findings to experiments employing random assignment are described and used as referents in discussions of validity considerations. The collection of observational data is recommended for use…

This paper suggests that since continuing professional educators must address the ever present gap between new knowledge and practitioner competence, accurate identification and prioritization of practitioners' educational needs must be maintained on a continuous basis. Describing an adult education agency as an open system whose output depends on…

This report provides descriptive statistical information from Phase III-B of the Beginning Teacher Evaluation Study. Within the sample of second and fifth grade teachers in classrooms in public schools in California, approximately six students were identified as target students to be studied during the school year. These students were observed…

This manual was developed for Compliance Safety and Health Officers (CSHO) of the Occupational Safety and Health Administration (OSHA) to help them carry out their responsibilities when investigating workplace accidents. The content is presented in four sections. The first overviews the investigative roles of CSHO officers, including…

The book provides practical guidelines for the layman who is interested in researching, writing, and publishing local history. Two standards considered to be essential to the writing of local history are ethics and competence. The three aspects of competence which are discussed focus on researching, writing, and publishing. Chapter I identifies…

Suggestions and learning activities to help secondary students learn social studies skills are contained in this document. Social studies skills make it possible for the learner to employ those intellectual processes necessary in obtaining or handling knowledge. Five selected skill development areas are discussed; each area contains a number of…

This study reports an attempt to measure implementation of Head Start Planned Variation, a national experiment designed to compare the relative effectiveness of 12 education models. The report first gives the background of the experiment, describes the problem of attempting to assess effectiveness without first measuring implementation, and…

The pamphlet describes an evaluation model for crime reduction projects developed by National Institute of Law Enforcement and Criminal Justice sponsored research. It is meant to assist justice agency and project managers in determining completeness of evaluation planning by providing a framework against which to measure their evaluation…

This paper describes the design, installation, testing, and operation of a computer-based record keeping system for computer terminals and equipment. The system provides all levels of data management for maintenance with instantaneous reports on location of equipment, cost of equipment, cost of repairs, inventory and parts control, as well as a…

This handbook presents a pilot evaluation model developed with the cooperation of occupational education staff members from the two-year colleges of New York State. The project staff, the steering committee, and principal consultants began with the assumption that evaluation can be a valuable and continuous part of program effort, providing…

The results are briefly summarized of a study to investigate the relationship of factors other than job skills (such as social skills, life style, mobility, family relationships, and contextual factors) to the long range success of vocational and technical training programs. Data were gathered about students in secondary and postsecondary…

Since problems associated with the statistical methodology of educational research are becoming increasingly important, this paper examines a subset of problems associated with the analysis and interpretation of aggregated data. Two major questions arise: (1) if a researcher knows the level (e.g., individual, teacher/classroom, school, school…

The present paper contributes to research methodology as practiced in the field by providing practitioners with a concise statement of the problems in analyzing unbalanced designs, and by clarifying the conditions under which the analysis alternatives are most appropriate. The purposes of the present paper are: (1) to examine the analysis…

The study focused on the individual attributes predictive of performance and work satisfaction in two contrasting work situations: (1) with a simple task to be perceived as low on job structural attributes (LJSA) and (2) with a more complex task designed to have a higher level of job structural attributes (HJSA). The job structural variables of…

The study integrates various elements of past approaches to job design. It focuses on determining individual characteristics associated with performance and work satisfaction on a simulated maintenance task designed to be seen as low in job structural attributes (LJSA) by one group and the same task designed to be perceived as high in job…
