摘要：This paper is intended to adds to the emerging dialogue on best practices in teacher education for preparing future teachers to use technology to promote grounded theory‑based practices in their classrooms. In it, I report on an evolving model f or such training that resulted from a a longitudinal case study examiningning how changes to teacher trainees identities, learning and teaching practices changed when they are exposed to the use of a variety of social networking technologies for languag e learning in the context of their teacher preparation program in a private university in Chile. . The 12‑month classroom‑based case study was conducted at a private university in Chile, using a variety of ethnographic tools . observation, interviews, an d online conversation analysis. I investigated how the integration of certain ICTstechnology into their content courses, as opposed to more traditional stand‑alone courses on technology use, mattered both in terms of the way the participants. The approach to technology used mattered both in terms of making a difference in the ways that these pre‑service teachers viewed themselves as learners and as future teachers of language, as well as of their evolving perspectives on the use of technology for learning and teaching. My aim in conducting the study was twofold: 1) to determine was twofold. First, I examined whether innovative technology‑ infused (TI) courses would serve to enable the beginning teacher participants to shed their traditional, passive, rather narrow cultural mindset as individuals and learners that are contrary to the identities of effective, 21st century teachers; and 2). Secondly, I sought to determine to see whether opportunities for these individuals to use a variety of innovative technologies for their own learning would have an influence on the pedagogies these individualsy themselves employed in their teaching practices. Would technology‑infused courses lead to teaching with technology? While the longitudinal study provided enc ouraging signs on both accounts within the teacher preparation program, questions remained about whether the model would be supported where it mattered in real classroom teaching. In this article, I report on follow‑up acknowledging the challenges wit hin classroom‑based research and the complexities involved in social science‑based qualitative and numbers‑based findings that suggest that, generally, the positive changes were not sustained. These findings provide strong support for the need for teacher education models to be tested in real practice. Importantly, they also uncover the essential ingredient for promoting future teachers uptake of effective use of ICTs collective support from the Teacher Education stakeholder community research para digms in drawing generalizable conclusions, the data analysis clearly confirms that there were encouraging signs for both aims for this particular group of pre‑service teachers. This study should be of interest to all stakeholders in education, most espe cially those whose responsibility it is and who may struggle with practical strategies to ensure that pre‑service teachers have the identities, skills and tools necessary for providing quality 21st century education programs.
