Teaching philosophy : moving from face-to-face to online classrooms

This article explores the similarities and differences between Canadian and Australian university teachers’ face-to-face and online teaching approaches and philosophies. It presents perspectives on teaching face-to-face and online in two comparable Canadian and Australian universities, both of which offer instruction in these two modes. The key research question was to determine if moving from face-to-face instruction to on-line teaching results in new teaching approaches or in a creative blend of those developed within each teaching modality. Qualitative data were collected using an open-ended survey, which asked participants for their thoughts on their face-to-face (f2f) and online teaching experiences. Quantitative data were collected using the “Teaching Perspectives Inventory,” which assessed participants’ teaching approaches and philosophies in terms of their beliefs, intentions, and actions. The authors’ conclusions address the issue of assisting teachers to successfully make the transition from traditional teacher-centred to newly emerging learner-centred teaching approaches in distributed classrooms.

Individual stable space : an approach to face recognition under uncontrolled conditions

There usually exist many kinds of variations in face images taken under uncontrolled conditions, such as changes of pose, illumination, expression, etc. Most previous works on face recognition (FR) focus on particular variations and usually assume the absence of others. Instead of such a ldquodivide and conquerrdquo strategy, this paper attempts to directly address face recognition under uncontrolled conditions. The key is the individual stable space (ISS), which only expresses personal characteristics. A neural network named ISNN is proposed to map a raw face image into the ISS. After that, three ISS-based algorithms are designed for FR under uncontrolled conditions. There are no restrictions for the images fed into these algorithms. Moreover, unlike many other FR techniques, they do not require any extra training information, such as the view angle. These advantages make them practical to implement under uncontrolled conditions. The proposed algorithms are tested on three large face databases with vast variations and achieve superior performance compared with other 12 existing FR techniques.

Classification of face images using local iterated function systems

There has been an increasing interest in face recognition in recent years. Many recognition methods have been developed so far, some very encouraging. A key remaining issue is the existence of variations in the input face image. Today, methods exist that can handle specific image variations. But we are yet to see methods that can be used more effectively in unconstrained situations. This paper presents a method that can handle partial translation, rotation, or scale variations in the input face image. The principal is to automatically identify objects within images using their partial self-similarities. The paper presents two recognition methods which can be used to recognise objects within images. A face recognition system is then presented that is insensitive to limited translation, rotation, or scale variations in the input face image. The performance of the system is evaluated through four experiments. The results show that the system achieves higher recognition rates than those of a number of existing approaches.

A controlled trial of internet-based cognitive-behavioural therapy for panic disorder with face-to-face support from a general practitioner or email support from a psychologist

Background: Panic disorder (PD) is one of the most common anxiety disorders seen in general practice, but provision of evidence-based cognitive-behavioural treatment (CBT) is rare. Many Australian GPs are now trained to deliver focused psychological strategies, but in practice this is time consuming and costly.

Objective: To evaluate the efficacy of an internet-based CBT intervention (Panic Online) for the treatment of PD supported by general practitioner (GP)-delivered therapeutic assistance.

Design: Panic Online supported by GP-delivered face-to-face therapy was compared to Panic Online supported by psychologist-delivered email therapy.

Methods: Sixty-five people with a primary diagnosis of PD (78% of whom also had agoraphobia) completed 12 weeks of therapy using Panic Online and therapeutic assistance with his/her GP (n = 34) or a clinical psychologist (n = 31). The mean duration of PD for participants allocated to these groups was 59 months and 58 months, respectively. Participants completed a clinical diagnostic interview delivered by a psychologist via telephone and questionnaires to assess panic-related symptoms, before and after treatment.

Results: The total attrition rate was 20%, with no group differences in attrition frequency. Both treatments led to significant improvements in panic attack frequency, depression, anxiety, stress, anxiety sensitivity and quality of life. There were no statistically significant differences in the two treatments on any of these measures, or in the frequency of participants with clinically significant PD at post assessment.

Conclusions: When provided with accessible online treatment protocols, GPs trained to deliver focused psychological strategies can achieve patient outcomes comparable to efficacious treatments delivered by clinical psychologists. The findings of this research provide a model for how GPs may be assisted to provide evidence-based mental healthcare successfully.

Is internet-based CBT for panic disorder and agoraphobia as effective as face-to-face CBT

This study compared Panic Online (PO), an internet-based CBT intervention, to best-practice face-to-face CBT for people with panic disorder with or without agoraphobia. Eighty-six people with a primary diagnosis of panic disorder were recruited from Victoria, Australia. Participants were randomly assigned to either PO (n = 46) or best practice face-to-face CBT (n = 40). Effects of the internet-based CBT program were found to be comparable to those of face-to-face CBT. Both interventions produced significant reductions in panic disorder and agoraphobia clinician severity ratings, self reported panic disorder severity and panic attack frequency, measures of depression, anxiety, stress and panic related cognitions, and displayed improvements in quality of life. Participants rated both treatment conditions as equally credible and satisfying. Participants in the face-to-face CBT treatment group cited higher enjoyment with communicating with their therapist. Consistent with this, therapists’ ratings for compliance to treatment and understanding of the CBT material was higher in the face-to-face CBT treatment group. PO required significantly less therapist time than the face-to-face CBT condition.

Adaptive fusion of gait and face for human identification in video

Most work on multi-biometric fusion is based on static fusion rules which cannot respond to the changes of the environment and the individual users. This paper proposes adaptive multi-biometric fusion, which dynamically adjusts the fusion rules to suit the real-time external conditions. As a typical example, the adaptive fusion of gait and face in video is studied. Two factors that may affect the relationship between gait and face in the fusion are considered, i.e., the view angle and the subject-to-camera distance. Together they determine the way gait and face are fused at an arbitrary time. Experimental results show that the adaptive fusion performs significantly better than not only single biometric traits, but also those widely adopted static fusion rules including SUM, PRODUCT, MIN, and MAX.

The changing face of the Australian teaching profession : new generations and new ways of working and learning

Today’s workforce is characterised by an increasing mix of people with varying career aspirations, work motivators and job satisfiers. This paper discusses the intergenerational nature of today’s workforce, which is currently dominated by the age groups commonly referred to as Baby Boomers and Generation X. The Baby Boomers defined and redefined work during the last quarter of the twentieth century, but as they track towards retirement, GenXers’ valued work patterns and their career and life aspirations are increasingly dominating. This paper draws on a body of literature about a younger generation of workers and the current world of work in today’s knowledge society, and discusses possible implications for the teaching profession, particularly for attracting and retaining young people as teachers.

The changing face of literacy policy in Victoria

In the transition from the twentieth to the twenty-first century, literacy has undergone a fundamental change in the shift from page to screen as the dominant basis for communication. In a communications environment characterised by multimodality - integration of modes of linguistic, visual, audio, gestural and spatial modes of meaning - young people require a broadened repertoire of literacy capacities.
Educational authorities with responsibility for literacy policy have responded in terms of curriculum, and assessment advice within a context of rapidly changing forms of multimodal communication. This paper details the early twenty-first century response of one educational authoríty, the Department of Education, Victoria, in reviewing early years literacy curriculum and assessment in light of the rapid developments in digital communications.

Windfarms, powerlines and phone masts : the changing face of stigma

Previous research has identified varying degrees of stigma attached to high voltage overhead transmission lines (HVOTLs) depending upon characteristics such as visibility, size, location and the potential impact on house value. In addition to HVOTLs there are other common types of infrastructure, namely mobile phone towers and windfarms, that are also large highly visible
structures and can exhibit similar characteristics. These similarities include varying levels of visibility from properties in the immediate vicinity, a high general profile in society and varying perceptions from surrounding residents about possible side effects. This research broadens the framework originally developed to study HVOTLs to encompass mobile phone towers and windfarms. It undertakes a literature review of research in this area and proposes a research methodology for identifying and quantifying the varying levels of stigma attached to these three forms of infrastructure. The final results will enable the resulting effect on property values to be better understood, and assist developers to fully understand their effect on devaluing land prices.

A new screen face for public service broadcasting

The contemporary broadcasting industry is characterised by technological and social change, it is increasingly competitive, and the media industry is fragmenting. New services need not necessarily compete with existing free-to-air broadcasting but could act as further incentive for audiences to invest in new equipment. New equipment will be necessary in the future as set out under the Television Broadcasting Services (Digital Conversion) Act 2000 (Cth), before the planned switch-off of analogue broadcasts planned for this year but now likely to be 2013. By then, however, audiences might already have migrated to the online environment for television and radio content as well as other services. Those that produce and deliver programs via free-to-air broadcasting need to consider what audiences do with new media in order to engage them. This will be an ongoing process as technology and audience expectations continue to change. Against such a background, this article examines how Australia’s public broadcasters are responding to the new media environment. It will consider their interactive online programs and services with specific analysis of ABC’s new ‘iView’ and ‘ABC Fora’ which offer content on-demand. It will also examine SBS online initiatives. I wish to argue that the new media offer public broadcasters new prospects to provide forums and spaces for education, entertainment, public discussion and interaction online.
