Abstract :
This paper deals with audiovisual distance lectures over IP networks and assesses educational effectiveness for various values of the video encoding bit rate and playout buffering time by experiment. The educational effectiveness is evaluated in terms of satisfaction and understanding. We investigate the satisfaction in a multidimensional way by the SD method with many adjective pairs. The understanding is expressed by the learning quotient (growth rate), which is defined as the ratio of the correct answer in the pre-test to that in the post-test. As a result, we find that the satisfaction closely correlates with adjective pairs for picture quality. In addition, we notice that the learning quotient has a strong relationship to adjective pairs for student´s motivation and interest.
