PRE-TASK OVERVIEW: Teacher has written relevant vocabulary words on the white board. Teacher sets up topic schemata by asking open-ended questions about the topic, introduces task and clarifies outcome (5 minutes). Teacher explains to students that they will complete a survey on embryonic stem-cell research (ESCR) and then prepare and participate in a debate arguing the pros and cons of harvesting stem cells. T informally asks students what they know about stem cells. Teacher asks students whether or not they know anyone who has received an organ donation, been an organ donor or needs an organ. Teacher asks students to name diseases that might possibly benefit from the harvesting of stem cells (Parkinson’s, Diabetes Alzheimers). T and S share personal stories. T asks if anyone knows the meaning of the word, pluripotent and circles the word on the white board. T groups students into two debating teams (Pro & Con). T tells Ss that each team must pick a scribe who will write a one-paragraph definition of pluripotent
