Composing an email : social interaction in a preschool classroom

The chapter contributes understandings of digitally mediated interactions in early childhood classrooms. Ethnomethodological and conversation analysis approaches are used to analyse a video-recorded episode of children and teacher composing an email in a preschool classroom. In their talk we find how the teacher directs the children to what counts procedurally, such as the components of an email, and the teacher’s moral work in producing a culturally correct way form of personal communication. Such considerations of situated examples can encourage investigations of digital practices that extend beyond operational skills to broader understandings of digital practices as cultural and situated activities.

Television content for the 21st century classroom

This thesis examines the confluence of digital technology, evolving classroom pedagogy and young people's screen use, demonstrating how screen content can be deployed, curated, and developed for effective use in contemporary classrooms. Based on four detailed case studies drawn from the candidate's professional creative practice, the research presents a set of design considerations for educational media that distill the relevance of the research for screen producers seeking to develop a more productive understanding of and engagement with the school education sector.

Critical literacy finds a 'place': Writing and social action in a low-income Australian grad 2/3 classroom

In a study of socioeconomically disadvantaged children's acquisition of school literacies, a university research team investigated how a group of teachers negotiated critical literacies and explored notions of social power with elementary children in a suburban school located in an area of high poverty. Here we focus on a grade 2/3 classroom where the teacher and children became involved in a local urban renewal project and on how in the process the children wrote about place and power. Using the students' concerns about their neighborhood, the teacher engaged her class in a critical literacy project that not only involved a complex set of literate practices but also taught the children about power and the possibilities for local civic action. In particular, we discuss examples of children's drawing and writing about their neighborhoods and their lives. We explore how children's writing and drawing might be key elements in developing "critical literacies" in elementary school settings. We consider how such classroom writing can be a mediator of emotions, intellectual and academic learning, social practice, and political activism.

But how do we know they watched it? Adapting to the flipped classroom conundrum

Those who teach film and media need to use screen content to illustrate their subjects. For example, students want illustrations to accompany lectures on film or television genres. Our experience has been that student access to the film and television screen content underpinning a study of genres is not only desirable but is, in fact, crucial for effective teaching and learning outcomes. Not so long ago, a screening during or at the completion of a lecture was the expected method by which educators delivered screen content to illustrate their teaching. Even if student attendance fluctuated from week to week a quick head count confirmed that a certain number of students were physically present. It was assumed that this physical attendance encouraged students to reflect upon and contextualize the material post lecture. While simply attending a lecture will not translate into actual student learning, it does demonstrate a willingness by students to engage with the course content by making a commitment to attend a scheduled and recurring lecture and screening program. However, as flipped classroom models gain acceptance in educational institutions, this traditional lecture-screening model is giving way to online, off-site, and student-controlled mechanisms for screen content delivery and viewing. Nevertheless, care should be taken when assessing how online delivery translates into student engagement and learning. As Junco (2012) points out, “it’s not the technology that generates learning, but the ways in which the technology are used.” Discussed, debated, and embraced to varying degrees by educators, there remains no definitive model for the flipped classroom – although many models involve ‘flipping’ content and knowledge acquisition (including viewing films and television shows) from scheduled on-campus classes to online material viewed by students in advance of an on-campus lecture or class. The classroom or tutorial room then becomes a space to problem-solve, engage in collaborate learning, and advance and explain concepts. From an institutional perspective, the flipped classroom model could deliver an additional benefit beyond immediate pedagogical concerns. Tucker (2012) suggests through the flipped classroom model “all aspects of instruction can be rethought to best maximize the scarcest learning resource — time.” The narrative most often associated with this shift is that the move to online content delivery of lecture and cinematic / televisual material may also provide educators with more time to do other work such as engage in research, plan strategies to empower students. Experimentation with the flipped classroom model is playing out in various educational institutions. Yet several core concerns remain — one of these concerns is the crucial question of whether an online/digital flipped approach is more effective for student engagement and learning than the traditional lecture-screening mode for screen content delivery. Some urge caution in this regard, arguing that “new technology isn’t always supported by change management and professional development to ensure that digital isn’t just a goal within itself, but actually helps to transform education” (Fleming cited in Blain 2014). The most fundamental concern remains how do lecturers, instructors, and tutors know students have watched the films and television shows associated with a subject? The remainder of this discussion deals with these concerns, and possible solutions offered, through an analysis of the Film, Television and Screen Genres subject at the Queensland University of Technology (QUT) in Brisbane, Queensland.

Understanding classroom trouble through regulative gravity and instructional elasticity

This paper aims to develop a more nuanced analytic vocabulary to typify how and where classroom trouble can manifest in pedagogic discourse. It draws on classroom ethnographies conducted in non-academic secondary school pathways and alternative programs in Australian communities with high youth unemployment, where the policy of ‘earning or learning’ till age 17 has effectively extended compulsory schooling. Three concepts are developed and exemplified: ‘regulative flares’, being moments when teachers resort to explicitly reasserting the lesson’s social order; ‘moral gravity’ to describe the degree to which the moral order underpinning the regulative discourse is tied to the immediate context or beyond; and ‘instructional elasticity’ to account for trouble originating in the instructional register.

Approximate nearest-neighbour search with inverted signature slice lists

In this paper we present an original approach for finding approximate nearest neighbours in collections of locality-sensitive hashes. The paper demonstrates that this approach makes high-performance nearest-neighbour searching feasible on Web-scale collections and commodity hardware with minimal degradation in search quality.

Bhutanese eighth grade students' and teachers' perceptions of their classroom learning environment in relation to the new mathematics curriculum

This thesis examined how Bhutanese eighth grade students and teachers perceived their classroom learning environment in relation to a new standards-based mathematics curriculum. Data were gathered from administering surveys to a sample of 608 students and 98 teachers, followed by semi-structured interviews with selected participants. The findings of the study indicated that participants generally perceived their learning environments favorably. However, there were differences in terms of gender, school level, and school location. The study provides teachers, educational leaders, and policy-makers in Bhutan new insights into students' and teachers' perceptions of their mathematics classroom environments.

Multidimensional classroom support to inclusive education teachers in Beijing, China

Classroom support plays a salient role in successful inclusive education, hence it has been widely debated in the literature. Much extant work has only focused on a particular aspect of classroom support. A comprehensive, systematic discussion of classroom support is sporadic in the literature. Relevant research concerning the Chinese context is even more limited. To address this gap, our study developed and validated a multidimensional classroom support model conducive to teachers’ inclusive education practices. Data were drawn from our large-scale survey with inclusive education teachers in Beijing. Further analyses were conducted to compare different dimensions within the classroom support model. Drawing insights from the results, we provide some recommendations for practice and research.

Charge transport studies in donor-acceptor block copolymer PDPP-TNT and PC71BM based inverted organic photovoltaic devices processed in room conditions

Diketopyrrolopyrole-naphthalene polymer (PDPP-TNT), a donor-acceptor co-polymer, has shown versatile behavior demonstrating high performances in organic field-effect transistors (OFETs) and organic photovoltaic (OPV) devices. In this paper we report investigation of charge carrier dynamics in PDPP-TNT, and [6,6]-phenyl C71 butyric acid methyl ester (PC71BM) bulk-heterojunction based inverted OPV devices using current density-voltage (J-V) characteristics, space charge limited current (SCLC) measurements, capacitance-voltage (C-V) characteristics, and impedance spectroscopy (IS). OPV devices in inverted architecture, ITO/ZnO/PDPP-TNT:PC71BM/MoO3/Ag, are processed and characterized at room conditions. The power conversion efficiency (PCE) of these devices are measured ∼3.8%, with reasonably good fill-factor 54.6%. The analysis of impedance spectra exhibits electron’s mobility ∼2 × 10−3 cm2V−1s−1, and lifetime in the range of 0.03-0.23 ms. SCLC measurements give hole mobility of 1.12 × 10−5 cm2V−1s−1, and electron mobility of 8.7 × 10−4 cm2V−1s−1.

Mathematics knowledge for teaching and the classroom environment

This study investigated the classroom environment in an underperforming mathematics classroom. The objectives were: (1) to investigate the classroom environment and identify influences upon it, and (2) to further explore those influences (i.e., teacher knowledge). This was completed using a diachronic case study approach in which data were gathered during lesson observations and coaching sessions. These data were analysed to describe and exemplify the classroom environment, then further described against forms of teacher knowledge. Conjectures regarding the importance of teacher knowledge of content were made which formed a base for developing a model of teacher planning and pedagogy.

Design theory for innovation of classroom-based information systems

This research used design science research methods to develop, instantiate, implement, and measure the acceptance of a novel software artefact. The primary purpose of this software artefact was to enhance data collection, improve its quality and enable its capture in classroom environments without distracting from the teaching activity. The artefact set is an iOS app, with supporting web services and technologies designed in response to teacher and pastoral care needs. System analysis and design used Enterprise Architecture methods. The novel component of the iOS app implemented proximity detection to identify the student through their iPad and automatically link to that student's data. The use of this novel software artefact and web services was trialled in a school setting, measuring user acceptance and system utility. This integrated system was shown to improve the accuracy, consistency, completeness and timeliness of captured data and the utility of the input and reporting systems.

How talk and interaction unfold in a digitally enabled preschool classroom

The use of mobile digital devices, such as laptops and tablets, has implications for how teachers interact with young students within the institutional context of educational settings. This article examines language and participation in a digitally enabled preschool classroom as students engage with teachers and peers. Ethnomethodology, conversation analysis and membership categorization analysis are used to explicate video-recorded episodes of students (aged 3-5 years) interacting while using a laptop and a tablet. Attending to the sequential organization (when, how) and the context relevance (where) of talk and interaction, analysis shows how the intersection of interactions involving the teacher, students and digital devices, shape the ways that talk and interactions unfold. Analysis found that the teacher-student interactions were jointly arranged around a participation framework that included: 1) the teacher’s embodied action that mobilizes an accompanying action by a student, 2) allocation of turn-taking and participation while using a digital device and, 3) the affordances of the digital device in relation to the participants’ social organization. In this way, it is possible to understand not just what a digital device is or does, but the affordances of what it makes possible in constituting teachers’ and students’ social and learning relationships.
