At first, 5 of the students do not understand well because they get confused with the concept of redox reaction. They also cannot apply the previous knowledge on this subtopic. Therefore, teacher recalls back the previous lesson and try to give new examples of redox reaction equation. Teacher shows step by step to make sure they understand better. Finally they are able to identify the processes and agents that involved in redox reaction from the chemical equation given by teacher. Teacher gives several questions to evaluate them. Students discuss among themselves to solve the problems. Today's objectives are achieved.
