The primary purpose of this study was to examine the inhibitors affecting classroom teaching by surveying the perceptions of secondary teachers. This purpose was based on the growing crisis of "teacher burnout" which was thoroughly documented. Since it appears that burnout most often affects those teachers who work in conventional classrooms, characteristics of teaching effectiveness within these classrooms were the basis for inhibitor comparison. Seven characteristics were produced by a crosstabulation of studies on effective teaching spanning the last fifty years. The inhibitor choices presented with these seven characteristics were extracted from an extensive list produced by the literature and classified under six areas of origin. The characteristics and inhibitors ultimately selected were surveyed among teachers in a large Southwest metropolitan area.
