This parental coaching includes three phases: preparation, implementation and evaluation. The participants of the study are 16 parents and their children. The data of the study was obtained through the following data collection tools: family information form, focus group interview, semi-structured interviews conducted with parents and children, social network group logs, questionnaire and academic achievement scores of children. Descriptive analysis was used to analyze qualitative data and Wilcoxon "t" test for quantitative data. The issues which the parents ask for support are guidance for supporting their children in the courses they have problems with and help children to develop reading and study habits. The findings of the study show that parental coaching via social network increases teacher-parent, parent-parent and parent-child interaction as well as children's academic achievement.
