Martyn Hammersley 
Classroom Ethnography [PDF ebook] 
Empirical and Methodological Essays

Apoio

Originally published in 1990, Classroom Ethnography examines the interplay between empirical research and methodological reflection. It explores the nature, the methods, the role, and the limitations of ethnographic research on school classrooms. Beginning with examples of Hammersley’s empirical research, the book then moves on to a number of reflections about the methodology of ethnographic research, covering such matters as the role of theory and the relative contributions of qualitative and quantitative work. Classroom Ethnography will be of use to those with an interest in educational research methodology and, in particular, of ethnographic research on classrooms.
