This report is based on an action research study conducted in an English language course with a group of low-residency students of a teacher education master's program: "Multilingual Technologies of Early Childhood Education," at Kazan Federal University. A Social Networking Site (SNS), Facebook, was used as a platform for practising and developing the students' teaching skills. The purpose of the study was to show the students the potential educational value of Facebook in teaching English to preschool children. The data sources include pre- and post-project questionnaires, interviews with students, field notes, and the reflective diary of the instructor-researcher. The results show that while designing an educational page on Facebook, the students changed their attitude towards the educational value of SNSs and acquired knowledge and skills necessary for implementing SNSs into their teaching practices. The research findings will be of interest to English language educators, especially foreign language teachers involved in early childhood education, and to Computer Assisted Language Learning (CALL) practitioners.
