The feedback step has one stage. This is “Go back to related step”. The feedback process involves revise
instruction based upon the data collected during the implementation phase. If, during the phase, teacher finds that students are not learning what the plan wanted them to learn, and/or they are not enjoying the learning process,
teacher will want to go back to related step and try to revise some aspect of their instruction so as to better enable
their students to accomplish their goals. If there is a problem in input step, instructional designer will go back to
input step. Then, instructional designer will make changes and start process from input. This process will be
done until all goals and objectives are learned by learners. During this cycle, instructional designer may go back
to any steps to where a problem is occured.
