This booklet summarizes research observations of the last 15 years about techniques and characteristics of effective teachers. The booklet presents information to assist teachers in the classroom, to stimulate discussion, and to promote effective approaches. Effective teaching cannot always be measured, yet effective teachers have a major effect on students' futures. Following reports in the mid-1960's that teachers could do little to change the influence of the home on students' achievement levels, researchers during the 1970's discovered that teachers and schools do in fact have substantial effects. The book briefly discusses 15 characteristics and techniques found among effective teachers, who, for the most part: (1) tend to be good managers, (2) use systematic instruction techniques, (3) have high expectations of students and themselves, (4) believe in their own efficacy, (5) vary teaching strategies, (6) handle discipline through prevention, (7) are caring, (8) are democratic in their approach, (9) are task-oriented, (10) are concerned with perceptual meanings rather than with facts and events, (11) are comfortable interacting with others, (12) have a strong grasp of subject matter, (13) are accessible to students outside of class, (14) tailor teaching to student needs, and (15) are flexible and imaginative. Thirty-five references, from which the summary is drawn, are appended. (CJH)
