66 QUANTITY AND QUALITY IN SOCIAL RESEARCH ccrned with Ihc process of implementation rather tliiin solely with its outputs (Finch, 1986). Thus ;i qualitative research approach would emphasize the various responses of both those who implement and those who are affected, the interpretations they invoke of the policy initiative, how they respond to each other's views, how perspective! change, and so on. Similarly, in his participant observation study of n comprehensive school, Ball (1981) was interested in the way in which a major innovation the introduction of mixed-ability groupings - was implemented. Hall documents not only the sequence of events that this innovation comprised, but also the variety of responses of the teachers. He found that In the absence of an agreed or imposed 'mandate* for change, the teachers at Beachside were free to attribute their own categories of meaning to the innovation . . . Furthermore, the absence of a mandate for change also meant that the teachers were not obliged to change their teaching methods. Indeed, in some respects constraints inherent in the culture and ethos of the school militated against drastic changes in the organization of learning in the classroom. (Mall, 1981, p. 237) Thus Ball concludes from his investigation of the meanings attributed to the change to mixed ability groupings that there was substantial variation in teachers' perspectives on it and that the extent of the impact of the change on their leaching practices may have been less pronounced than might otherwise have been anticipated. From the teacher's point of view. Ball shows, change is not a radical departure from a pre-existing state, but a gradual drifting away, and it is from this latter stance that he or she sees change as having occurred. Ball's analysis of the innovation entails treating it as a process whereby the change is introduced, then interpreted by teachers, and the implications of these interpretations for teaching practices are then examined. The final sentence in the above quotation also serves as a reminder of the qualitative researcher's inclination towards a contextual understanding, whereby the teachers' Interpretations of the change are grounded in the context of the school's ethos. Flexibility and Lack of Strw'turv Qualitative researchers' adherence lo viewing social phenomena through Ihc eyes of their subjects has led to a wariness regarding the imposition of prior and possibly inappropriate frames of reference on the people they study. Consequently, they tend to favour a research strategy which is relatively open and unstruc- tured, rather than one which has decided in advance precisely what ought to be investigated and how it should be done. It is also often argued that an open research strategy enhances the opportunity of coming across entirely unexpected issues which may Ik* of interest to the ethnographer. Participant observation particularly lends itself to this orientation because ihc researcher is i.....ieisc
