Je ne sais pas 

1. means "I don't know" in French.
2. also one of three answers you give your French teacher when he/she asks you a question that you don't know the answer too or are just too lazy to answer. (the others being "oui" and "non")

M/Mme/Mlle whoever: "Qu'est-ce qui s'est passé dans les chapitres que tu as lu hier?"
Student: "Ehh...je ne sais pas...mais c'était très intèressant?"

("What happened in the chapters that you read yesterday?" "Eh...I don't know...but it was very interesting?")
