[[alternative]]A Study of Behavior Analysis on Troubleshooting of Mechatronics Circuit System

[[abstract]]Abstract The purpose of this study was to set up the classified table of Mechatronics Circuit Troubleshooting, explore behavior of troubleshooting, analyze the factors affecting the efficiency on troubleshooting achievement and the correlation between prior-knowledge and troubleshooting achievement. The experimental students, having the pre-test of Mechatronics Circuit Troubleshooting, were selected 12 students divided into high score group and low score group from electrical engineering department of Technology Institute. The research method was thinking aloud/clinical interview and utilizing protocol analysis by recording tape and video tape searching for the behavior of troubleshooting and processes of Mechatronics Circuit Troubleshooting. According to the analysis of this case, the conclusions obtained were as follows: 1. Setting up the classified table of Mechatronics Circuit Troubleshooting. 2. Significant correlation exists between the students’ achievement of Mecha- tronics Circuit Troubleshooting and their prior-knowledge, both in declarative knowledge and procedural knowledge. 3. The ranking frequency of Mechatronics Circuit Troubleshooting was as follows: searching for troubleshooting, comprehension for symptoms, and executing troubleshooting behavior. The most frequency in comprehension for symptoms was visual behavior and the ranking frequency of searching for troubleshooting was as follows: sensory evaluation, electrical meter measuring, data analysis, and searching strategy. 4. The achievement comparison between high and low score group of prior- knowledge. (1) High score group could efficiently implement troubleshooting strategies. (2) Low score group had obstacles in troubleshooting resulted from insufficient prior-knowledge. 5. The influential factors in Mechatronics Circuit Troubleshooting achievement were as follows: (1) The main factor resulted in fail troubleshooting was insufficient prior- knowledge and technique. (2)Lack of experience in Mechatronics troubleshooting would increase troubleshooting time and decrease its efficiency. (3)The main factor in successful troubleshooting was students’ knowing well about its strategies and methods. Keywords: mechatronics, troubleshooting, thinking aloud.
