A study addressed the question, "If a teacher exhibits enthusiasm while instructing, what will be the effect upon measures relating to student achievement?" Student variables studied in relationship to teacher enthusiasm were (1) attendance; (2) interest in school and in the particular subject; (3) educational motivation; and (4) student rating of vocational teachers. The literature suggests these factors are related to some extent. Methodology involved having forty-three inservice vocational teachers submit two fifteen-minute videotaped teaching sessions wherein trained raters could assess the independent variable of teacher enthusiasm using eight carefully described criteria. Students at those sessions were tested, using appropriate instruments, for the selected factors, and a Product-Moment correlation statistic was used on the data. Conclusions, based on data analysis, were that no significant correlation exists between teaching enthusiasm and the selected factors with the exception of student rating of instructors, where the coefficient was marginally significant.
