Experimental vs. control group and teaching tool. How to do it ethically?

How can you use a teaching tool in the experimental group, while not using a teaching tool in the control group? Is it ethical in research? If not, how should 2 groups using a teaching tool?

If you are testing the effectiveness of the teaching tool, then they would use it in the control group. Ethics in research is if you tell the participants before the start of the experiment and agree to participate and sign a statement (both groups aware that one of them will have the tool and the other not.) You do not say take two different classes of children and teach a class teaching tool and not the other. That would be unethical because they were unaware that a group will be at a disadvantage in the experiment. If you have both groups using the training tool, then that not what you try. Remember that when you're performing an experiment that everything has to be equal in both groups, except what is being tested.
