Methods, Including CCTV, of Presenting Introductory Biology: Their "Affect" on College Freshmen.
Madson, Marland LeRoy
Reported is a study in which freshman students in biology with no prior experience of closed circuit television (CCTV) instruction were randomly assigned to three groups of 35 students each. All groups had one three-hour laboratory session weekly for one quarter. Additional weekly classes for Group A were three one-hour CCTV lectures and one one-hour discussion; Group B had three live lectures from the same professors who gave the CCTV programs and one one-hour discussion; Group C had the CCTV classes. The relationship between opportunities for personal contact with instructors and achievement and attitudes toward aspects of the course were investigated using four course examinations, a semantic differential, and an attitude inventory. One way analysis of variance, Newman-Kuels means analysis, and Chi-square tests were used. There was no difference in achievement between groups. Treatment C students, who only had contact with instructors in laboratory sessions, had a more positive attitude toward laboratories than the other groups. Group B students rated lecturers more positively than the other students did. The greater the opportunity for personal contact with the instructor the more positive the attitude towards different aspects of biology. (Author/AL)
