Tom rogers wanted to test a new "singalong" method to teach math to 4th graders (e. g., "i love to multiply" sung to the tune of "god bless america"). he used the singalong method in his first period class. his 6th period students continued solving math problems with the old method. at the end of the term, mr. rogers found that the first period class scored significantly lower than the 6th period class on a mathematics achievement test. he concluded that the singalong method was a total failure.
