In connection with the formative evaluation of the Developing Mathematical Processes (DMP) curriculum, interviews were conducted with teachers in grades 1-3 at the beginning of the school year and after concluding each of the 10 topics on addition and subtraction. The topics had been especially prepared for a classroom observational study. The topic interviews were conducted while the study was in progress, and were intended to ascertain the degree of importance teachers gave to a particular topic, as well as to impart information about how they planned instruction and about their classroom strategies. This report presents the responses of each teacher to each question, typed from the tape-recorded interviews. (MNS)
