The Self Lesson Report Form (SLRF) was designed as an alternative either to direct classroom observation or to commonly used questionnaires in which students and/or teachers report on general practices used in their classes. In the SLRF teachers report what happened in their last lesson. Certain items are structured while others are open. A special procedure was developed for the analysis of the open answers. A high level of reliability was obtained by comparing results of teachers' and observers' reports on the same lesson. Two hundred and fifty SLRF's were analyzed and the results are reported to illustrate the kind of information which can be obtained with this instrument. It was found that, on the average, junior high science classes in Israel are inquiry oriented, have abundance of discussions and hands-on laboratory activities which are closely supervised by the teachers.
