Modern education requires the use of ICT in the learning process as a part of the development of the information society. Primary schools in Slovenia follow the latest trends in e-learning, and have largely introduced web-based e-learning and distance education in the past few years. This contribution presents our research on the effects of web classrooms on the education process in Slovenia’s primary schools. We have gathered the data from teachers and pupils using web based questionnaires and analysed it with statistical tools. The results indicate that among other positive effects the use of web classrooms can also bring an improvement in the grades of pupils.
