Answer:
not giving one group the program
Explanation:
But there is a problem related to grade scores either. Probably Dr. Kenji should not give the program to any grade at first time. And in a second audition do it with the program in students´ hands.
The confounding variable in the research design developed by Dr. Kenji is that the program is not given to one group.
confounding variable is said to be those variables that would not be able to determine the true relation between dependent and independent variables of the research. This would give the researcher with wrong or misleading results by distorting the relationship between variables.
The research must be performed with groups that are similar such as in above case the program should be studied between the fifth-grade students only to get the accurate finding of the experimnet.
