This research conducted an investigation on vocational pre-service teachers’ performance based on Technological Pedagogical Content Knowledge Framework (TPCK) to support learning in 21st century. TPCK Framework integrated three kinds of knowledge needed by a teacher in providing learning process for students effectively. The results of this study found that vocational pre-service teachers had the knowledge of using technology understanding teaching pedagogies and mastering on content individually. However they were limited in blending such essential three domains together to form more effective learning process for their students.

The objectives of the study were to fine the survival probabilities the haazard rates of dropping out of the tecnical diploma level students at Rajamangala University of Technology phra Nakhon North Bangkok Campus and the factors influencing on the university in 2005. The study foud tht the frist semester the survival probabilities of students in all divisions were high ranging from 0.9210 to 1.00 For the second semester the survival probabilities of students in all divisions ranged from 0/7820 to 0.8815 except Industrial Technology which had a maximum value of 0.9295 aned Metal Technology which had aminimum value of 0.6271. For the third and the fourth semester there were 6 division which had survival probabilities ranging from 0.7142 to 0.7971. They were Tool and Die Making Computer technology Eletrical Technology Electronics Auromatic Machine and production design. They 4 were Mechanical Tool Technology Business Computer Mechanical Power and Industrial Technolog. the hazard rates of dropping of students in all divising were low ranging for 0.00 to 0.0822. For the second semester the hazard rates of dropping of students in all divisions ranged from 0.1260 to 0.2458 except Industrial technology which had a minimum value of 0.0730 and Metal Technology which had a miximum value of 0.5221. For the third and the fourth semester the hazard rates of students in all division ranged from 0.1355 to 0.2962 excepy metal Technology which had the maximum value of 0.5932 and Tool and Die Making which had the value of 0.3364. The factors influencing on hazard rates of students drpout were place of previous school region of previos school and grade point average of previons school. The hazard rate of dropping of students graduation from school in the central region (not including Bankok Metropolitan Area) was 43% (0.562 times) less than the hazard rate of dropping of students graduation from schools in Bangkok metropolitan area. The hazard rate of dropping of students having grade aveage of 3.10-3.50 and 3.51-4.00 from previous school was 43.1% (0.569 times) and 63.7% (0.377 times) less than the hazard rate of students having grade point average of 2.00-2.50 respectively.

This study aims to survey the trend of the demand of the industrial instructors of the wanted institutions and the producing organization especially for the Faculty of Industrial Education Rajamangala University of Technology Phra Nakhon so as to know exactly about the certain demand and to estimate the production of the industrial instructors sufficiently to their needs and upgrade their skill more efficiently including implementation plan and curriculum development. The population are administrators heads of the departments from the Office of Vocational Education Commission and the Administration Office of Private Education Enhancing Commission. 112 samples were drawn under sample procedure by using the purposive sampling. The tool used in this research is questionnaire concerning the demand situation of the industrial instructors in Thailand during 2007-2011 emphasis on the institutions using industrial instructors.
