Here is a list of ways for students to become active participants in the learning process:
Speed dating. Students sit in a line, in a row of desks. They each have a piece of information. Other students sit opposite them. The first row of students then have to teach the student opposite them the piece of information they have. The second row of students then all move along one and receive new information. At the end, they share all of their new knowledge.
Tag team questions. Teacher has sets of envelopes with questions in them, written on strips of paper. Teams of students are given one question that they have to take back to their team to answer. Once they have answered it, they come back to the teacher to get it checked, before picking up another question strip. The team that has collected the most question strips after a set period of time wins.
