Comparison to Learning Accomplishment for Making Electronic Products unit by soldering and insert methods of the electronic parts in Practical Arts Education

The purpose of this research is to compare between students learning achievement and teachers teaching efficiency in making electronic product by soldering or inserting method of the electronic parts. According to the result, in the completion rate of electronic product, inserting method was about 2 times higher than soldering method and to the failure rate, soldering method was 4 times higher than inserting method. To the question about the degree of difficulty for making the electronic product in two methods, about 3 times students felt easier inserting method than soldering method. Also in teachers opinion who instructed making electronic product, inserting method was more easy to teach students, takes less time to make electronic product, and students can easily repair by themselves to the error by simple instruction. The inserting method does not need any special laboratory, it does not pollute the environment because the electronic parts can be recycled, and student could safely do the work without any smoke from the lead and dangerous factors of the heat. For many reasons, inserting method has more advantages than soldering method. In the view of the primary goal of practical art education-feel the joy of achievement and know the meaning of working-inserting method of the electronic parts is more efficient than soldering method in making electronic product.
