This book channels some research concepts about teacher and child behavior and its settings into ideas that can be used by teachers in an informal analysis of his/her own classroom learning environment. It is particularly directed to kindergarten and primary school teachers, although some nursery school and upper-grade teachers may find it of interest as well. Eight chapters address the analysis of teaching-learning environments focusing on physical settings. Dimensions that are analyzed are softness/hardness; open/closed; simple/complex; intrusion/seclusion; and high mobility/low mobility. Sections on thrivers versus nonthrivers and teachers as decision-makers are included. Seven chapters analyze teaching-learning environments in terms of teacher behavior. Dimensions considered here are teacher opens/teacher closes, teacher simplifies/teacher complicates, teacher permits intrusion/teacher provides seclusion, teacher permits high mobility/low mobility, teacher is soft/hard. A section on learning through play and work is included. The last chapters address changes over time in the analysis of teaching-learning environments and discuss two approaches to classroom management: simplification and enrichment. This presentation assumes that the teacher is the principal decision-maker in an educational system. (Author/AM)
