The development of technology education in Taiwan has been in a huge change since the new Grade 1-9 Curriculum was fully and nationwide implemented in the 2004 school year; the two curriculum, Living Technology and Science, have been combined into the new learning areas--named "Science and Technology" for the new Grade 1-9 Curriculum. All of the teachers of grade 1-9 almost have had no choice but facing the impact that was caused by the implementation of the new curriculum. The study was aimed to the sense of instructional efficacy of the technology teachers of junior high schools under the existing conditions in Taiwan. To fulfill the study purposes, a questionnaire survey was utilized to gather the data from the in-service Living Technology teachers of junior high schools in Taiwan. The seven main conclusions as following were drawn from survey findings: (1) LT teachers' senses of instructional efficacy in junior high school in Taiwan need to regard and promote in near future. (2) The situation of science teachers dominate the whole curriculum of LT is more than 23%. This caused many LT teachers are not able to teach LT curriculum or teach a few. (3) Most of LT teachers have part-time position to spend time in administration. This seems a signal of Taiwan's LT in the crisis. (4) The evaluation to the job value of teaching LT in junior high school, most of the LT teachers felt disheartened at government's policy of technology education and acquired other instructional license in order to keep the other teaching job in future. (5) The present situation of technology education of junior high schools in Taiwan is in the risk. All of the three main factors of affecting LT teachers' senses of instructional efficacy come from administration of their schools, the government, and the community or society. There will have no spaces or opportunities for LT instruction in junior high schools in Taiwan in future. (Contains a 30-item bibliography and 1 figure.)
