Gopalakrishnan and Vijayalekshmi have written two books based on their experiences in education; ‘Thaangavunna Vidyabhyaasam’ and ‘Kalipaadhangal’. ‘Thaangavunna Vidyabhyaasam’ tells their story as teachers, as parents and as social beings. Social problems and the reason behind them are analyzed through the eyes of responsible citizens while presenting a solution to these in the form of Sarang’s education system. ‘Kalipaadhangal’ was about children and the traditional games they play and which helped them develop mental and physical coordination.
