Abstract

The main purpose of this research was to study problems in organizing experimental science activities in Educational Regions II, III and IV. The Study took place under categories namely; preparation before experimentation, the suitability of experimental rooms, material and equipment; availability of water and power supplies, student motivation, and teacher competence. The subject of this research were 422 science teachers at goverment schools in the Educational Region II, III and IV. The research instruments used were questionaires and interviews constructed by the researcher and validated by OC-coefficience. The data were analyzed by using frequency talling, arithmetic means, standard deviation, t-test and analysis of variance. The results of the research were the following: 1. In general, the degree of problems range from low to moderate. 2. There were more problems related to physics experiments than biology and more related to biology than chemistry. 3. Schools in Educational Region II have more problems than those in Educational Region III which have more problems than those in Educational Region IV
