individual teacher strengths in planning for instruction and in working with learners.
2 Team teaching spurs creativity because teachers know they must
teach for their learners. 3

contact between teacher and learner. 4
Team teaching provides for better sequencing and pacing of increments of instruction because perceptions of an individual
teacher must be verified by at least one other team member. 5

in their group to achi eve the objective of the study and groups‟ success. Here,
each student can practice the social skills in a group. They will get ideas and even new information about the related material from their group members.
They learn to be responsible and give participation simultaneously. In cooperative learning, not only teachers as the source of learning process, but also

cooperative learning can enhance the students‟ motivation and reduce students‟ stress because of using a good and positive classroom climate.
