ABSTRACT. Research findings indicate that teachers' beliefs play an important role in their deciding how they will integrate technology into the classroom. The author used qualitative research methods to explore the relations between teachers' pedagogical beliefs and technology integration. Participants were 12 Taiwanese high school teachers, and findings indicated inconsistency between the teachers' expressed beliefs and their practices. The author categorized the reasons for the inconsistency into 3 interrelated aspects: (a) the influence of external factors, (b) teachers' limited or improper theoretical understanding, and (c) teachers' other conflicting beliefs. The author presents suggestions for school settings, professional development, and future research.Keywords: constructivist instruction, teacher belief, technology integration esearchers have suggested that a crucial factor for successful technology integration into the classroom is the teacher (e.g., Bitner & Bitner, 2002;Loveless, DeVoogd, & Bohlin, 2001;Romano, 2003;Zhao & Cziko, 2001), because what directly determines the instruction that takes place behind the classroom door is the teacher rather than external educational agenda or requirements (Hodas, 1993;Tyack & Cuban, 1995). Researchers have found that teacher beliefs play a critical role in transforming teachers' technology integration into more constructivist practices (e.g., Bitner & Bitner; Dexter, Anderson, & Becker, 1999;Ertmer, 1999Ertmer, , 2005Niederhauser & Stoddart, 2001;Ravitz, Becker, & Wong, 2000;Sandholtz, Ringstaff, & Dwyer, 1991Windschitl & Sahl, 2002). Therefore, the relations between teachers' beliefs and teachers' practices should help to shed light on how teachers make technology-integration decisions.Judson (2006) and Levin and Wadmany (2006) specifically investigated whether teachers' technology use in classrooms would reflect the teachers' pedagogical beliefs, and regarding this technology use the researchers' findings confirmed the existence of an inconsistency between (a) teachers' expressed beliefs about such use and (b) teachers' practices. Judson stated that novice teachers' perception of instruction situations may differ from expert teachers' corresponding perception and that, consequently, novice teachers' technology-use practices may be inconsistent with their positive attitudes toward constructivist concepts. However, such an explanation merits further investigation. In their 3-year study, Levin and Wadmany found that teachers' technology-use practices and pedagogical beliefs had changed reciprocally, and that teachers seldom held pure educational beliefs. However, Levin and Wadmany did not provide other reasons for the inconsistency between teachers' beliefs and practices in technology use. Therefore, the purposes of the present study were (a) to investigate whether teachers' pedagogical beliefs align with their practices regarding technology integration and (b) to explore the reasons for any inconsistency between teacher beliefs and teacher practices.Since 1...
