The problem of this study was to measure the effect upon the tone quality of singers resulting from identifying a specific goal, modeling with a cassette tape of the student's own voice, prescribing practice, and giving verbal approval. On the basis of the findings, these conclusions are drawn. (1) There is no significant difference in prescribing practice of an identified goal, utilizing a model or giving verbal approval. (2) Higher gain in pretest - posttest scores for the experimental groups while the control group showed the lowest gain suggests these teaching methods may be effective. (3) A high correlation of raters can be attained by the training method used in this study.

The problem of this investigation was the development of a systematic method for the evaluation of curricula in baccalaureate nursing programs. The literature in nursing and general education was used to extrapolate theories and concepts for the formulation of a theoretical construct. This construct served as the basis for the evaluation instrument. The major concepts were identified as (1) underlying structure, (2) content of courses within the curriculum, and (3) methods and activities. Elements and components were chosen to clarify and extend the concepts. The literature and experts in nursing were both instrumental in the selection of weights. Based on the findings of the study, the following conclusions are made. (1) A faculty member's ability to use a systematic evaluation instrument does not depend upon years of teaching experience or prior experience as a National League for Nursing visitor. (2) The Evaluation Index appears capable of meeting the criteria for a more systematic method of curriculum evaluation. (3) A theoretical construct appears conducive to theory development as it is directed toward an approach which is more scientific than intuitive. (4) The inclusion of clarifying components within the instrument provides for the evaluative effort to be distributed across the entire curriculum …
