2. 2 1.The class is organised in cooperative base groups of 3 students. They remain together all the semester and work mainly in group. 1 2 3 4 5 6 1 2 3 4 5 6 1 2 3 1 1 1 A class with the same timetable 1) Give each student a different number 2 2 2 Lets prepare a puzzle/jigsaw G11 3 3 3 G13 G12 3GM11 / 3GM12 2) Put together students with the same number Random base groups formation:

3. 3 2.Divide the assignment to the learned into 3 segments. For example a design flow of a circuit using 3 different techniques Assign each student to learn one segment. So, every base group will have a member expert in a given segment. 1 1 1 2 2 2 A C B C A B Lets prepare a puzzle/jigsaw 3 3 3 B C A

4. 4 3.Form temporary informal "expert groups" by having one student from each jigsaw group join other students assigned to the same segment. Give students in these expert groups time to discuss the main points of their segment and to rehearse the presentations they will make to their jigsaw group. 1A 1C 1B Base group G11 1A 2A 3A Expert group in segment A 3B 4B 5B Expert group in segment B 1C 2C 3C Expert group in segment C Lets prepare a puzzle/jigsaw 2A 2C 2B Base group G12

5. 5 5.Bring the students back into their base groups. Ask each student to present her or his segment to the group. Encourage others in the group to ask questions for clarification 1A 1C 1B Grup G11 2A 2C 2B Grup G12 Lets prepare a puzzle/jigsaw 5A 5C 5B Grup G06 Now, these students are experts on their segment The aim is that everyone learns all the segments, but being taught mostly by their own peers ! Just as in a jigsaw puzzle, each piece (each student's part) is essential for the completion and full understanding of the final product.
