I have international students that flock together in a group. They share notes and are caught talking during a test. When questioned about this talking, the reply is that the question makes no sense because of the language barrier and that the question is being explained in the native tongue. I have gone so far as to seperate the group, which was recieved in a negative manner and reported to the office for being prejudice against the group of students. I have taken students aside and explained that clarification of test questions is my responsibility and that talking during a test is not authorized. Then I catch them texting each other. It has gotten to the extreme that I have all phones turned off and put away under the penalty of failing the test if it rings or comes out. We do not take a break during a test. No eating, drinking, or use of tobacco. The word is getting out that I am a tough TESTMASTER. Cheating has declined and test scores dropped for a short time. Is there more that I can do to curb cheating without becoming a tyrant?
