O'Brien, Thomas C. – Educational Studies in Mathematics, 1972
Performance on the inference patterns of modus ponens, contrapositive, inverse, and converse was investigated; effects of mode and form used were studied. Half of the students in a high school, grades 9-12, were tested. Results showed an inability to recognize the validity of the contrapositive and better scores on inverse items than on converse.…
