”Classroom culture” is a new concept in the history of education. With assistance of different and various historic sources, this kind of research provides with an insight into certain historical stages. It helps to understand and interpret individual human experiences related to their school life, which is proved to be the environment that forms human personality, social relationships and strengthens the person’s spiritual and emotional development. In this article, both the theoretical aspects of the “classroom culture” concept and practical analysis of photographs and interviews are described. It also reconstructs the transformation of classroom culture in Latvia within the period from authoritarianism in the Soviet Union to democratic regime in the post-Soviet Latvia. Soviet Union’s government focused on the creation of a unified system of schools. The research of photographs and memories reveals the importance of the work and education at school at the time of the Soviet Union. The purpose of Soviet Union's education system is to raise a Soviet power, making equally minded people whose main challenge is hard work and to encourage the construction of socialism, and demonstrate the victory over capitalism. Source analysis reveals that class culture at the start of the restoration of Latvian independence transforms into a free open-classroom environment. The class is no longer a place for the learning process only, but also a place where students spend their free time intervals and celebrate the holidays with their parents or without them. There is no censorship in class photo shoots, and each person can photograph what they want.
