This article describes a study to investigate and describe methods of teaching evaluation used by departments of plant and soil science and agricultural economics at land-grant institutions in the United States. The study consisted of a mail survey and telephone interviews. The authors present the survey and interview data together, using the two data streams to clarify one another. They used chi-square frequency analysis, Duncan\'s Multiple Range Test, and Pearson-Spearman dependence and correlation procedures to analyze quantitative survey data. Qualitative results from surveys and interviews were analyzed by pattern coding.
