ABSTRACTWith the development of science and technology, the LED product with powerful functions comes into being. It can completely change the defects of general light source needed in the teaching process, but the teachers’ adoption intention of LED product are not high. The former researchers focus on the adoption intention of information technology integrating into primary school teaching. This study adopted the technology acceptance model (TAM) as theoretical framework to examine the factors that influenced the adoption intention of integrating LED into teaching of elementary schools.Based on the above research purpose, this study takes committees of elementary schools as research objects, and arranges related scale based on the literature results, and the data collected by questionnaire and purposive sampling is taken as sampling technique. Totally 221 questionnaires were sent out and 200 valid ones were retrieved.The research has discovered that (1)With diverse scale of schools, elementary school teachers’ adoption intention of LED product is not significantly different, but elementary school teachers who have more application experience of LED product more likely to integrate LED into teaching of elementary schools; (2) The basic hypothesis proposed by TAM were supported except that LED characteristic has no significant effect on the perceived easy using, and we guess that it is related to the LED products’ relative advantage, compatibility and complexity. (3)The external variables have significant effect on internal beliefs except that LED characteristic has no significant effect on the perceived easy using, and organizational factors have the most powerful effect on perceived easy using and perceived usefulness.Key words: Technology Acceptance Model, LED, Perceived Easy Using, Perceived Usefulness, Adoption Intention.
