Case Study “The class was beginning a unit on 'sexuality' that day. They came in from lunch and Mr. Clark asked everybody to calm down and get ready to work. But everybody was a little nervous and excited, and it took a long time before the jokes and laughter let up. When it was quiet, Mr. Clark asked whether anyone knew what kinds of things they'd be studying in this next unit called ‘human growth and development.' Marco raised his hand and asked, 'What about the reproductive system?' A few people giggled. Then Shawna raised her hand. She asked whether the class would learn about menstrual periods. Four or five people began to roar with laughter and Michelle said 'How dumb!' Shawna started to blush. When the laughter kept up, tears came to her eyes and she finally got up and left the room.”

Questions to Consider 1. If you were the teacher, how would solve this problem? 2. How can we prevent this from happening here?

Ground Rules No put downs (including yourself) Protect people’s privacy Be considerate of the feelings of others Save questions for Q & A period (teacher will announce when) Write down any questions you may have until the session for questions starts.

Sex vs. Sexuality Sex and Sexuality are not the same. Sex means gender (for ex: male or female) Sexuality includes how a person feels about him or herself, what they feel about being male or female, whether they know how to love, how to trust, how to communicate.
