In the 78th regular conference of the Ministers of Education in West Germany, which was held on the September 29.30, 1960 in Saarbriicken, a reform proposal on the upper grade of Gymnasium was carried with acclamations. This agreement is called "Saarbriickener Rahmenvereinbarung". The aims of this agreement are the reduction of the number of required subjects and the concentration of teaching materials in order to turn the strengthening of teaching into a possibility and promote the student's mental-reliance and responsibility. In accordance with the agreement, an elective program was introduced. The courses which changed into the electives are mainly the natural sciences; namely, physics, chemistry and biology. The science teaching in the upper grade of Gymnasium changed sharply by the elective program, but it has suffered harsh criticism from many persons who had concern with science education. In this article, an outline of the reform and some problems in science education in West Germany subsequent on the conclusion of Saarbriicken agreement are discussed.
