AN EXPERIMENTAL STUDY UTILIZING CLOSED-CIRCUIT TELEVISION IN THE TEACHING OF DENTAL TECHNIQUES.
MORRISON, ARTHUR H.
CLOSED CIRCUIT TELEVISION WAS WELL RECEIVED BY DENTISTRY STUDENTS AT NEW YORK UNIVERSITY BUT FAILED TO YIELD SIGNIFICANT GAINS IN ACHIEVEMENT OVER CONVENTIONAL INSTRUCTION. TWENTY-ONE NULL HYPOTHESES WERE TESTED ON 154 MALE SOPHOMORE STUDENTS, WHO WERE DIVIDED INTO GWO GROUPS, HALF BEING INSTRUCTED TO A LARGE EXTENT VIA CCTV, TV CLASS, AND HALF BEING TAUGHT CONVENTIONALLY, CV CLASS. THE GROUPS WERE MATCHED ON THE BASIS OF PREDICTED GRADES ON (1) WRITTEN WORK, AND (2) PRACTICAL WORK. ALTHOUGH, THE CV CLASS HAD A SIGNIFICANT ADVANTAGE ON PREDICTED GRADES IN WRITTEN WORK--COMPENSATED FOR BY USE OF COVARIANCE ANALYSIS--THERE WAS NO SIGNIFICANT DIFFERENCE BETWEEN CV AND TV CLASSES IN ACHIEVED WRITTEN GRADES. IN TWO OF THE THREE TRIMESTERS UNDERTAKEN, LITTLE DIFFERENCE WAS FOUND IN ACHIEVED PRACTICAL WORK BETWEEN THE CLASSES, BUT IN THE THIRD TRIMESTER THE CV CLASS HAD SIGNIFICANTLY HIGHER PRACTICAL GRADES. ATTITUDES TOWARD INSTRUCTION WERE SIGNIFICANTLY MORE FAVORABLE IN THE TV CLASS, BUT THERE WAS NO EXPECTED INTERACTION BETWEEN ATTITUDES AND ACHIEVEMENT. WRITTEN EXAMINATIONS, USING THE FLANAGAN ITEM-SELECTION TECHNIQUE, WERE DEVELOPED AND PRETESTED FOR THE STUDY, AND CHECK-OFF SHEETS WERE DEVELOPED TO STANDARDIZE GRADING OF PRACTICAL WORK. STUDENT ATTITUDES WERE MEASURED BY SCALES WITH AVERAGE RELIABILITY (KUDER-RICHARDSON 20) OF .91 WITH A RANGE OF .88 TO .97. A REVIEW OF THE LITERATURE AND BIBLIOGRAPHY ARE GIVEN. APPENDICES INCLUDE SCALES, TABLES, AND COURSE OUTLINES. (OH)
