    Understanding teachers' practices and the factors influencing their practices when designing multimodal representations in the topic of temperature and heat
    (2024)
    Wong, Wai Lit
    As society and economy develops, the focus in science education changes in tandem. While the changing focus in science education necessitates a change in the teaching and learning of science, it is widely reported that teachers face issues and challenges coping with new demands of teaching science. One of the current practices of science education focuses on the use of multimodal representations, which has the potential to develop students’ understanding in science, enhance their critical thinking and reasoning and promote science as a way of thinking. However, studies have shown that teachers face challenges in using representations in ways to enhance students’ learning. Thus, to overcome the challenges, this study seeks to understand teacher’s practices and the factors influencing their practices when Designing multimodal representations in the science classroom. Taking a situated perspective of knowledge to underpin the concepts of enacted pedagogical content knowledge (ePCK), pedagogical reasoning and Designing, this study aims to document the selected modes of representations by the teacher and students, the pedagogical actions taken by teachers during the moment-to-moment interaction with the students during the Designing process, the thinking behind those actions taken and the components of ePCK that influences the actions taken. Through a case study approach, this study showed that Designing need not be a linear process due to the situated factors affecting the teacher’s orchestration, and some of the pedagogical actions critical in helping students make meaning include clarifying, connecting, and constructing explanations. Importantly, this study also revealed the interplay of the various components of ePCK and the critical influence of ePCK: knowledge of representation (conceptual and pedagogical) in influencing teacher’s actions such that the scientific meanings construed are aligned to the intended learning outcomes of the lessons. The findings will contribute to the professional development programs on the use of multimodal representations in science teaching. It also advances the literature in the area of PCK (distilling the ePCK: knowledge of representation into three sub components of ePCK: knowledge of representation (conceptual, pedagogical and epistemological) and multimodal representation studies whereby the traditional focus is on the externalization of the meanings made with the representations rather than what influences those actions taken during a communicative event. While there are limitations to this study, it represents a novel attempt to understand teacher’s practices and what affects their practices situated in the classroom context and contribute to the knowledge and skills needed for teachers to carry out effective representational-based inquiry science lessons.

    Translanguaging pedagogy in teaching English: A case study of a middle-school classroom in China
    (2024)
    Yin, Shihui

    Translanguaging has become a buzzword in the past decade. The concept of translanguaging has been interpreted from various perspectives, i.e., psycholinguistic (Li, 2018), sociolinguistic (García & Otheguy, 2019) as well as pedagogic (Creese & Blackledge, 2010; García, Johnson, & Seltzer, 2017). The last perspective is this thesis’s focus. The thesis investigated the contexts where translanguaging was employed as pedagogy and analyzed its potential advantages in an English-learning classroom in China.

    As an emerging pedagogy, research regarding translanguaging has been conducted in different multilingual countries and reported a positive reply from many researchers and scholars. However, few studies have been conducted in largely monolingual countries, such as China, where the concept of translanguaging is nascent. In comparison to multilingual societies, bilingual education in China follows a different path in which English is taught as a foreign language and serves as enrichment for students’ career development. Therefore, the effectiveness of this pedagogy, proven in a multilingual environment, is questioned when applied to largely monolingual English as a Foreign Language (EFL) countries, especially in middle and high schools, which are highly examoriented in China.

    Drawing on the 12-hour data collected through observations in a middle school EFL classroom, this thesis employed qualitative content analysis methods adopted from grounded theory and identified five contexts where translanguaging was used by the participating English teacher. Each context was elaborated with translanguaging examples of the teacher and students’ interactions, followed by discussions of the practices’ potential benefits, as well as the concerns of duplication, if any. In particular, two translanguaging practices designed by the teacher were explained and concluded in steps. The impact of pedagogical translanguaging was concluded by analyzing the teacher and students’ interactional patterns and students’ Mean Length of Utterance (MLU).

    Given that there is a relative lack of attention given in the literature to Chinese teachers’ and students’ attitudes regarding translanguaging in EFL contexts, two semi-structured interviews were conducted with the teacher, providing an indepth understanding of the teacher’s beliefs on translanguaging and its effectiveness in teaching. Furthermore, questionnaires from all students in the participating teacher’s class and one-on-one interviews with five focal students were collected and utilized to document students’ stances on translanguaging and its impact. Findings from both sides demonstrated complexity regarding teacher’s language use and students’ language use.

    This thesis is expected to contribute to the understanding of pedagogical translanguaging in an EFL context. More specifically, this thesis sheds light on the application of translanguaging to leverage the students’ entire linguistic repertoire for maximal learning in satisfying the needs of examinations and real life communication.

    Assembling and emplacing women's minoritised narratives through critical public art practice
    (2024)
    De Rozario, Regina

    This thesis discusses the development of a framework for a critical public art practice that is informed by aspects of assemblage thinking and making. It examines how developing a text-based audio experience might serve as such a form of critical art practice and be used to assemble and present narratives of minoritised groups such as queer groups, as well as relay notions of queerness and divergence to the public. For my investigation. a critical public art practice is defined as a practice that produces artistic works and encounters in public space that provoke critical reflection and engagement with the spaces one shares and inhabits with other individuals and communities. The term queer here is expanded beyond its use as a sexual orientation identifier to refer to individuals or groups who may orientate differently from heteronormative expectations.

    My investigation is situated in Singapore. where considerable governmental efforts and resources have been spent in the last three decades to activate public spaces for artistic encounters that promote the multicultural vibrancy of the city (Daniel. 2018; National Arts Council [NAC]. 2022a). Despite the government's growing interest to support a diverse range of narrative expressions and artistic representations. artworks emplaced in public space tend to exclude artworks that reference minoritised identities and lived experiences—such as that of my own (female. minority race. queer). Given the states repeal of its anti-sodomy law in November 2022. as well as changing attitudes among Singaporeans towards queer individuals and groups (Ipsos. 2022). this thesis broadly asks if it would be possible for current public art guidelines to be augmented with a more critically reflective and inclusive approach. In turn what would a framework for a more critical and inclusive public art practice that includes notions of queerness look like?

    My methodology comprised both autoethnography and an artistic case study. Through autoethnography. I provide my perspective of the hierarchical relationships. modes of assessment. and pragmatic decision-making processes that tend to be centred in the production of art for public space. The artistic case study describes the development of a text-based audio artwork developed for solo listening public space. For my theoretical frame. I looked to assemblage thinking. a mode of understanding how systems might work by applying notions of nonhierarchical configurations. multiplicities. fluidities, contingencies. and agencies (Baker & McGuirk. 2017; Deleuze & Guattari. 1987). In particular. I consider how these notions might be present in the practice of making art for public space and enabled through a format such as text-based audio. Responses to my artwork were then reflected upon alongside a contextual review of literature and artworks; data from the conversational interviews that informed the artwork:, and my own intersectionally situated knowledge of public art practice and minoritisation. These were synthesised to conceptualise a framework of key aspects for enacting a critical and more inclusive public art practice. as well as potential implications and challenges of weaving minoritised and dominant narratives together in an artistic encounter. In sum, the thesis seeks to contribute to scholarship in contemporary public art practices as well as to policymalcing involving the production of art for public space.
