Students´ technological concepts and attitudes have been researched for just over three decades. The chapter addresses several viewpoints concerning the construct of attitudes toward technology, such as definitions of attitude, and fundamental reasons for measuring students´ attitudes. The main part of the chapter presents the Pupils´ Attitudes Toward Technology-Netherlands (PATT-NL) instrument and the PATT-USA instrument associated with the classical PATT studies, as well as the PATT Short Questionnaire (PATT-SQ) as a recent adaptation of PATT-USA. It also focuses on new instruments, such as the Attitudinal Technology Profile (ATP) questionnaire that were developed based on regional and contextual factors. The latter part of the chapter provides general research findings from the PATT studies on students´ attitudes toward technology, as well as examples of recent multidimensional versus unidimensional studies.
