This longitudinal multiple-case study applies Activity Theory to analyse the integration of ePortfolio into an International Baccalaureate (IB) Middle Years Programme (MYP) Sciences classroom in Hong Kong SAR, China. Activity Theory was used as an analytical framework to examine eight IB MYP 2 students' (aged 12-13) experiences of Google Sites over two academic years of face-to-face, online, and blended learning modes of teaching and learning. Two classes of 21 students were understood as one Activity System with the inclusion of ePortfolios (Tool) that affected multiple Elements. These include participating students (Subjects), classroom norms (Rules), peers and parents (Community), feedback tasks (Division of Labour), uploading and presenting digital artefacts (Object), and personal skills-based motivation (Outcomes). Qualitative data analysis of ePortfolio artefacts and semi-structured interviews at three stages of intervention revealed two secondary contradiction themes that might have impeded ePortfolio update consistency: 1) Tool-related (unawareness of Tool affordances and misplacement of resources) and 2) Community-related (unfamiliarity with Community members' roles and conflicting feedback expectations). Recommendations (Tool-related affordances and recommendations and monthly timeline with Community roles) for ePortfolio implementation in MYP classrooms are outlined.

This study draws on the activity theory to explore how bilingual first-year secondary school students appropriate resources strategically in response to linguistic challenges in learning science through English in Hong Kong. The study explored 12 bilingual students' self-regulated strategy use by conducting in-depth interviews, stimulated recalls, observation and analysis of learning materials. Through analyzing these data, we examined how and why they appropriated and used resources strategically for self-regulated learning. The analysis revealed that the participants had used various artefacts (e.g. dictionary) and rules (e.g. evaluation criteria) to negotiate their respective roles (e.g. subject content learners and language learners) in situated communities of learning that consist of subject teachers, classmates, family members, private tutors and friends. Similarities and differences were found between the high achievers and the underachievers with regard to the use of resource-mediated strategies and the underlying reasons. The results inform the development of pedagogical schemes to enhance bilingual students' self-regulated strategic learning of academic subjects through English. Copyright ©Routledge.

Although the importance of practicum for preservice teachers goes almost unchallenged, specific empirical evidence of growth in language teachers’ practical knowledge in the under-researched context of preservice language teacher education is limited. Informed by both the reflective approach to teaching and an activity theory perspective, this qualitative case study examines what types of classroom practices a group of ESL student teachers learned in practicum experiences, and what pedagogical strategies they appropriated to achieve their learning of those goal-oriented classroom practices. The study is different from the previous teacher reflective thinking studies in that the study participants reflected on their practice teaching experiences, and such reflections were further tested in real-classroom situations and resulted in transformational learning. The results show that the student teachers’ learning of effective classroom practices was essentially prompted by reflection of the challenges and dilemmas encountered in the learning-to-teach process. The study points to the importance of foreign and second language teacher preparation programs promoting and sustaining a culture of reflection to empower preservice language teachers to anticipate or cope with the uncertainties and challenges they will encounter in the practicum experience, which is essential to meaningful learning and knowledge construction.
