This feasibility study contains a design for evaluating vocational education research and development (R & D). The study developed a model for evaluating vocational education R & D based on legislative frames of reference for research, exemplary projects, and curriculum development. Called an Impact Tracer Model, the program is based on information and observations taken from distribution records of 308 vocational education R & D products, utilization data from 12 exemplary products distributed nationwide, and impact data from 6 field sites. The five-stage model consists of needs assessment, product development, product dissemination, product use, and product impact. Some of the conclusions reached through the study are the following: (1) distribution data are easier to acquire and less expensive to obtain than product use or impact data; (2) most research coordinating unit directors are willing and able to provide distribution data; (3) superficial data on use can be obtained by mail, but detailed documentation requires observation or interviews; (4) baseline measurements should be established when assessing impact; (5) interactive methods are necessary for collecting impact data; and (6) data on product use and impact are collected by few states at present. The study recommends that a comprehensive and continuing vocational education R & D evaluation system be implemented in phases beginning with the collection of distribution data on all qualified R & D products. The appendices include survey instruments and a conceptual framework for assessing impact. (KC)
