disappointed, however, that Stodolsky finds the presentation overly complex and inadequately integrated, especially because I thought we had made good progress in this regard in developing the book from the technical report of the study. I suspect that the problem resides at least in part in the complexity of the study itself: the technical report has 750 manuscript pages, of which several hundred are devoted to complex tables. In contrast, the book is 206 pages of which only twenty-three are devoted to tables, and these tables are simplified considerably from the originals. Furthermore, the last four chapters (of eighteen) are devoted to summary and discussion of the material. Thus, considering the scope and complexity of the study, the book is a summary of the important findings rather than a detailed presentation of all of the findings. I believe that the data presentation is as streamlined as it can be without omitting or distorting the results. Integrative explanation of the results is another matter, however. Stodolsky is correct in noting that the large sample size and other innovative design features of this study did not succeed in enabling us to resolve all of the issues we set out to investigate and that more analytical work and theory development are needed. Again, part of the problem here is the complexity of the study: the sheer number and variety of findings defy integration or analysis with a few theoretical concepts. On the other hand, we made real progress in resolving some of the ambiguities of earlier research. The combination of the large sample with finer distinctions in types of student behavior considered, attention to stability of student behavior across 2 school years as reported by two teachers, and coding of initiationreaction sequences in teacher-student interaction enabled us to determine that teachers' expectations and attitudes are based mostly on students' academic performance, classroom conduct, and response to the teachers, and not on physical or status characteristics. We also show that teachers' patterns of interaction with students labeled as objects of teacher indifference are actually due to the passivity of those students and their failure to respond to persistent teacher efforts to reach them, and not to any genuine teacher indifference. Similarly we show that students who misbehave frequently but do not become alienated from their teachers are different from rejection students who share a pattern of mutual hostility with their teachers (the latter students, whether or not they misbehave often, persistently treat teachers with hostility and rejection, which eventually are reciprocated). These and other resolutions of issues raised in earlier research are discussed in the summary chapters, although perhaps not as thoroughly as they should have been. Stodolsky's criticism has some merit in that, although the issues stressed in the early chapters describing the rationale for the study are discussed in the summary chapters, they are not treated systematically in ways that the early chapters might lead the reader to expect. In trying to figure out why, I have become aware that a gradual shift over time occurred in how we (the authors of Permission to reprint this reply may be obtained only from the author.
