| Summary: | 碩士 === 國立體育大學 === 運動科學研究所 === 105 === The advent of information technology made learning motor skill through multimedia possible and error-detection ability is essential to self-regulate learning under no instructor condition. In order to study the effect of multimedia instructional video content sequence to the learner’s error-detection ability, this research used sixty (male:33; female:27; age: 22.0±1.0 yrs old) four-years university students with no tennis or racket sports experience as subjects. Two demonstration videos were designed: A: explain body Center of Gravity (CG) first follow by racket trajectory; B: explain racket trajectory first follow by body CG. Participants were randomly assigned to watch the videos to build-up their cognitive schema. The SMI RED remote eye tracker is used to capture participant’s gaze trajectory when watching the beginner’s Tennis forehand drive motion. A cellphone is used to record the participant’s dictation of detection of errors. Data gathered were analysed with independent t-test (α=.05). The results indicate that: 1. participants watching different video content sequence allocate their visual distribution differently, with the arm and truck AOI significantly different; 2. The AOI of arm and truck in backswing stage were significantly different; 3. In waving and follow through stage only the arm AOI exhibit significant difference. 4. In error-detection, watching the A instructional video group exhibit significant error-detection results. The results indicate instructional video content sequence affect the learner’s error-detection visual trajectory and ability. The author suggests that emphasize on body CG in tennis forehand drive instruction process can be favourable to the error-detection ability.
