Over one-half of the Finnish elementary school system has always been comprised of one to two teacher schools, and this bulletin contains two papers dealing with those small school systems. "The Finnish School System and Small Schools" by Pekka Silventoinen describes the conditions that created Finland's predominantly small school systems and the population shifts and birth rate trends that are causing many small schools to close (2070 have been closed thus far). Preservation of schools in sparsely populated areas is considered a better solution than centralization of school systems in population agglomerates, and the paper describes measures being taken to preserve small schools. Instruction in small schools is carried out in combined grades and "Development of Combined Grade Instruction" by Reijo Laukkanen presents statistics describing the system and discusses some of the most central problems of developing instruction for combined grades. "Period" instruction of modern subjects often necessitates juxtaposition of usual study sequence, and experiments designed to correct some of the problems in period instruction are described. Advantages and disadvantages of combining grades are discussed along with the special demands made on teachers and the materials they use. (DS)
