Of the eight major programs mentioned in Thailand's Eighth National Education Development Plan (1997-2001), one is aimed at developing human capability in the areas of science and technology. This is to address the fact that the teaching of technology in Thailand is lagging behind the technological changes of the last decade. Part of this reform effort is the development of conceptual based learning activities in science and technology for 12 to 15-year old students. These concepts are being introduced through the offering of a subject at the high school level. de Klerk Wolters (1989) indicated learning the concepts of technology is necessary and should be required for all students of this age range. Cross and McCormick (1986) added that students in both primary and secondary schools need to learn to solve technological problems in creative ways. Students also should understand the nature of technology. Understanding technology is just as important for Thai students as it is for students in other countries.
