I place students in different age and gender groups and have them do up to date research on the powerpoint information from their smart phones. We then have a lively discussion on the pertinent information.
Some of the powerpoint information is outdated and no longer relevant to some of the subject matter. We then have discussions and i feel that the students feel more bought in to the lessons as they can participate in the direction of their education, and participate more.
I also use that discussions for assessment purposes, so that everyone has the responsability to participate in the discussion.
