After China resumed the sovereignty of Hong Kong, the Curriculum Development Council encouraged schools to experiment with Putonghua as a medium of instruction (PMI) to teach the Chinese language. A review of the literature indicates that there have been problems in implementing the switch to the new medium of instruction (MOI). The aim of this exploratory case study is to investigate in more detail the problems that teachers and administrators of a secondary school face in implementing the new policy. Based on interviews, classroom observation, and documentary analysis, it is shown that conflicts and tensions have arisen from the incongruent beliefs of teachers and administrators regarding the rationale and impact of the PMI policy. Moreover, inadequate knowledge of Putonghua among teachers and students, a shortage of appropriate teaching resources, and the absence of helpful support from the government create further barriers to effective teaching and learning in the new programme. This paper argues that it is problematic for schools to translate any MOI policy into action if policy-makers fail to address the challenges that teachers and administrators encounter in switching to a new MOI.

Teacher-student interaction in classrooms is perceived to be crucial for learning. Previous research has compared the interaction in classrooms where a second language is used as the medium of instruction (MoI) with those where the mother tongue is used. This has been done mainly via qualitative impressions. The current study adopted a mixed method design to examine objectively and comprehensively the classroom interaction in a sample of Hong Kong secondary schools that used Chinese as the MoI from Grade 7 to 9, but then switched to English from Grade 10 onwards (i.e. MoI-switching schools). By doing so, this study aimed to identify the possible effect of a change in the MoI on classroom interaction and its potential for learning. Sixty lessons were observed in Grade 9 and 10 in three MoI-switching schools and compared to two schools where English was used throughout all the grades. The results show that, when the MoI changed from students' first to second language, lessons tended to become more teacher-centred and there were fewer opportunities for negotiation of meaning and scaffolding. These findings have significant implications for the relationship between the MoI and classroom interaction and provide important insights into pedagogy and teacher development.

Immediately after the handover of Hong Kong to China, the teaching of Chinese in Putonghua was promulgated by the Hong Kong SAR government as a long-term goal. However, no clear definition and guidance regarding Putonghua instruction has been provided to teachers to facilitate the smooth implementation of this change. A review of the literature indicates that teachers' beliefs have great value in assisting them to make sense of changes and govern their thoughts and behaviours. However, little is known about how teachers' beliefs help teachers to understand the transition to a new medium-of-instruction (MOI). Thus, the aim of this case study is to examine how teachers' beliefs help teachers to conceptualize the Putonghua medium-of-instruction (PMI) and how these beliefs affect their curricular decisions as well as the implementation of PMI. Data were collected from 10 secondary Chinese Language teachers in one school using semi-structured interviews and classroom observations. The findings revealed that since teachers held misconceptions about PMI in the initial phase, the implementation of PMI led to a shift of focus away from Chinese content knowledge. In the second phase, PMI was perceived merely as a code-switching device, and, as a result, only a surface change occurred that appeared unlikely to facilitate effective teaching and deep learning. This paper concludes with the observation that code switching alone is insufficient to achieve a successful transition of MOI if the deeper issue of teachers' beliefs is neglected.
