This study attempts to compare the thinking abilities of homemaking girls with the thinking abilities of girls not taking homemaking. By emphasizing the problem-solving method in the teaching of an experimental unit, it proposes to determine whether homemaking students show greater gains in thinking ability at the end of the school year than non-homemaking students. The investigator proposes to find out if the student taught by techniques of problem-solving forms thinking habits superior to habits formed by those students who have not been taught by this method as extensively as homemaking students.
