This study investigated the impact of the use of computer technology on the enactment of ''inquiry'' in a sixth grade science classroom. Participants were 42 students (38% female) enrolled in two sections of the classroom and taught by a technology-enthusiast instructor. Data were collected over the course of 4 months during which several ''inquiry'' activities were completed, some of which were supported with the use of technology. Non-participant observation, classroom videotaping, and semistructured and critical-incident interviews were used to collect data. The results indicated that the technology in use worked to restrict rather than promote ''inquiry'' in the participant classroom. In the presence of computers, group activities became more structured with a focus on sharing tasks and accounting for individual responsibility, and less time was dedicated to group discourse with a marked decrease in critical, meaning-making discourse. The views and beliefs of teachers and students in relation to their specific contexts moderate the potential of technology in supporting inquiry teaching and learning and should be factored both in teacher training and attempts to integrate technology in science teaching. ß 2006 Wiley Periodicals, Inc. J Res Sci Teach 44: 2007 Current reform efforts in science education envision science teaching that is inquiry-based and collaborative, and targets the development of student conceptual understandings, inquiry abilities and skills, and scientific habits of mind (American Association for the Advancement of Science [AAAS], 1990[AAAS], , 1993 National Research Council [NRC], 1996). Such a vision entails pedagogical and instructional approaches that are different from the traditional approaches that typify science teaching in the larger majority of K-12 classrooms. Instead, reform documents argue for providing students with opportunities to engage in authentic inquiry (National Research Council, 1996), which ''refers to the research that scientists actually carry out'' (Chinn & Malhotra, 2002, p. 177). ''When engaging in inquiry, students describe objects and events, ask questions, construct explanations, test those explanations. . ., and communicate their ideas,'' and throughout the process ''they identify their assumptions, use critical and logical thinking, and consider alternative explanations'' (National Research Council, 1996, p. 2). Inquiry provides an ideal context for helping students to achieve the desired scientific understandings, attitudes, abilities, and ways of thinking deemed essential for functioning and decision-making in an increasingly scientific-laden world (National Research Council, 1996). Edelson (1998), for instance, argued that science educators cannot expect students to achieve the aforementioned instructional outcomes if they continue to engage students in learning environments that are dissociated and qualitatively different from those within which scientists learn and function.The notion of replicating ''authentic scientific practice'' w...
