This report summarizes field work in Muglamp, Papua New Guinea, one of five community schools participating in the ongoing research and development efforts of the Indigenous Mathematics Project (IMP). It begins with an introduction to the site, the school setting, and the community setting. The teacher's history and the number of students in one grade 2, one grade 4, and two grade 6 classes are briefly noted. The evaluation of instructional activities indicated that the teacher did not have many problems implementing the lessons, although some suggestions were made to improve the teacher's notes. The learning aids were in general found to be appropriate and effective. Observations of language-use revealed that lessons were taught in English and Pidgin, with the latter used in decreasing amounts in grades 4 and 6. Classroom interaction was noted as predominantly teacher-centered, with questioning used often. Finally, student interviews are briefly reported. Overall, the IMP materials were found to be well-designed for this site. (MNS)
