One account tells of a sniper killing a mother and children at close range whom troops had told to leave their home.
Another speaker at the seminar described what he saw as the "cold blooded murder" of a Palestinian woman.
The army has defended its conduct during the Gaza offensive but said it would investigate the testimonies.
The Israeli army has said it will investigate the soldiers' accounts.
The testimonies were published by the military academy at Oranim College. Graduates of the academy, who had served in Gaza, were speaking to new recruits at a seminar.
"The climate in general... I don't know how to describe it.... the lives of Palestinians, let's say, are much, much less important than the lives of our soldiers," an infantry squad leader is quoted saying.
In another cited case, a commander ordered troops to kill an elderly woman walking on a road, even though she was easily identifiable and clearly not a threat.
One non-commissioned officer related at the seminar that an old woman crossing a main road was shot by soldiers.
"I don't know whether she was suspicious, not suspicious, I don't know her story… I do know that my officer sent people to the roof in order to take her out… It was cold-blooded murder," he said.
of course none of this was reported because the american media was taking guided tours by Israeli soldiers into staged altercations while the IDF was dropping white phosphorous into cradles and blowing up the UN headquarters.
remember that if you openly support israel you openly support a terrorist state!
