Methods For StudyingTeaching has been the subject of systematic inquiry for several decades. The first American Educational Research Association Handbook of Research on Teaching, edited by Nathaniel L. Gage, appeared in 1963 and later editions have appeared at approximately ten-year intervals. Since the 1960s there have also been a number of significant reviews of this research, such as Arnold Morrison and Donald McIntyre's 1969 and 1973 editions of Teachers and Teaching and Penelope L. Peterson and Herbert J. Walberg's Research on Teaching (1979). Such reviews have highlighted both the complexity of teaching and the fact that it is amenable to study from a number of perspectives, using a variety of methods.
