what so bad in israeli schools? i think we are the only country in the world were bible is a requirement for a matriculum.
Yes, the problem is they don't have a proper understanding of the "Bible" and they don't teach a proper or sufficient understanding of it. So they teach it, but they teach it incorrectly. Hardly a positive thing.
And while Israel may be the only State-mandated public school system that requires it, surely religious day schools and yeshivas throughout the world require it for graduation, and yet unlike Israeli public schools, in the Jewish schools they hire rabbis and orthodox educators to teach the Torah properly, whether the students follow it or not. So I fail to see how this meaningless statistic you give us is relevant to the subject at hand.
