Hi Heather, This is a very good way of having the students do individual or group research and then reporting on what they find. By allowing them to select a disease or condition they have personal involvement and choice as you say and this is very important in terms of motivation to do a good job. By setting a time limit you keep them focused and on target so they don't get carried away and spend extra time that is needed elsewhere. Another benefit is that students like to hear from each other and it helps develop their communication skills. So it is a win win for everyone. Gary
