Online teacher education : lessons from the cyber-trenches

This paper provides an overview of ‘lessons learned’ from the author’s decade long involvement in online teaching and learning, including eight years in the development, implementation, teaching and administration of a wholly online Master of Arts in Applied Linguistics coursework degree program, which attracted several hundred students annually from around the world, and has won awards for innovation, including being identified as a ‘flagship’ program during an external review of the university.

Emotional experiences of preservice science teachers in online learning : the formation, disruption and maintenance of social bonds

The enactment of learning to become a science teacher in online mode is an emotionally charged experience. We attend to the formation, maintenance and disruption of social bonds experienced by online preservice science teachers as they shared their emotional online learning experiences through blogs, or e-motion diaries, in reaction to videos of face-to-face lessons. A multi-theoretic framework drawing on microsociological perspectives of emotion informed our hermeneutic interpretations of students’ first-person accounts reported through an e-motion diary. These accounts were analyzed through our own database of emotion labels constructed from the synthesis of existing literature on emotion across a range of fields of inquiry. Preservice science teachers felt included in the face-to-face group as they watched videos of classroom transactions. The strength of these feelings of social solidarity were dependent on the quality of the video recording. E-motion diaries provided a resource for interactions focused on shared emotional experiences leading to formation of social bonds and the alleviation of feelings of fear, trepidation and anxiety about becoming science teachers. We offer implications to inform practitioners who wish to improve feelings of inclusion amongst their online learners in science education.

Enhancements to dielectric response measurements of oil-paper insulation for online and offline applications

The research introduces a promising technique for monitoring the degradation status of oil-paper insulation systems of large power transformers in an online mode and innovative enhancements are also made on the existing offline measurements, which afford more direct understanding of the insulation degradation process. Further, these techniques benefit from a quick measurement owing to the chirp waveform signal application. The techniques are improved and developed on the basis of measuring the impedance response of insulation systems. The feasibility and validity of the techniques was supported by the extensive simulation works as well as experimental investigations.

Problem-based learning in an online IT professional practice course

Educational research suggests that Problem-Based Learning (PBL) is a pedagogy that fosters a deeper understanding of the curriculum and provides students with processes and skills for lifelong learning. According to the literature this pedagogy appears to be a suitable one for teaching undergraduate information technology, yet adoption of PBL in information technology tertiary education appears to be slow. This paper discusses characteristics and processes of PBL and describes how the approach will be used in teaching information technology professional practice. The course described will be offered to information technology students in their final year of study and will be delivered wholly online. The course will not only provide best practice aspects of PBL but it will also provide students with the opportunity of undertaking authentic tasks using multimedia resources that simulate the real world.

Teaching practices for effective cooperative learning in an online learning environment (OLE)

As a teaching practice the application of cooperative learning in tertiary education can present unique challenges for both the practitioner and her students. Mastering this teaching approach requires careful planning, design and implementation for effective deployment in a face-to-face setting. In this setting the success of the cooperative learning approach has been demonstrated. The complexity is significantly increased by additional variables such as the selection and application of technological teaching tools and the change in nature of existing variables including awareness of students' social and communication skills when applying this practice in an Online Learning Environment (OLE). In addition student acceptance of this e-learning approach to learning also needs to be carefully considered. The practitioner must be aware of these factors and have suitable methods in place to support collaboration and interaction between student groups to ensure the ultimate goal with regard to students' learning is achieved. This paper considers how cooperative learning can be combined effectively with these variables and factors of an OLE, and begins with the presentation of a conceptual framework to represent this relationship as a constructive teaching practice. It is anticipated that the conceptual framework would be applied by other practitioners to facilitate cooperative teaching within their OLE. To demonstrate the validity of the framework a case scenario is provided using an Information Technology (IT) undergraduate unit named 'IT Practice'. This is a wholly online unit where extensive participation by the students within small groups is a core requirement. The paper demonstrates the themes of designing curriculum and assessment, as well as flexible teaching strategies for learner diversity but primarily concentrates on managing an effective OLE; that is managing small groups in an online teaching environment.

Conceptions of teaching with integrity online in higher education: a case in the field of engineering

The viewpoints of academic teaching staff take centre stage in the analysis of the changing conceptions of what it means to act with integrity when teaching online. To teach with integrity in contemporary online-supported environments in higher education is not necessarily to teach the same as if one would in teaching regularly face-to-face in the classroom. The paper argues that to teach with integrity online is to teach differently. With integrity both enhanced and in some respects diminished in teaching online, the apparent contradiction can only be resolved through developing conceptions of what teaching with integrity means in the contemporary world of higher education. Implications are drawn in the context of teaching extended and wholly online units in the field of engineering.

Online students : relationships between participation, demographics and academic performance

Using information technology to support teaching and learning is becoming ubiquitous in tertiary education. However, how students participate and perform when a major component of the learning experience is conducted via an online learning environment is still an open question. The objective of this study was to investigate whether any relationships existed between the participation, demographics and academic performance of students in an information technology course that was taught wholly online. Tracking data generated by the online learning environment was collected throughout the semester. Through a detailed analysis of this tracking data it was found that a relationship existed between students' participation in the online learning environment and their performance, as measured by final results in the course. Relationships also existed between gender, nationality, participation and performance. However, there was no relationship between age and performance and participation. These findings suggest that when designing online learning for a diverse population, student demographics should be taken into account to maximise the benefits of the learning experience. The results also suggest that the tracking data can be used as an early indicator of students who are likely to fail the course since lack of participation early in the semester is indicative of lower outcomes in the course. Being able to identify such students allows staff to take remedial action proactively rather than reactively in the latter part of the semester.

Application of podcasting in online engineering education

Applications of mobile technologies for engineering education can be found in the literature, but, many of the reported applications are aimed at the online (wirelessly), on-campus, synchronous and proximal use of mobile technologies. Mobile technologies in engineering education can encompass more than the proximal teaching and learning environment-they can be offline, asynchronous and at a distance from the classroom. This paper reports on the initial application of `podcasting' in a wholly online engineering study unit. It presents the rationale for, technical development details of, and, limited evaluation of this initial podcasting trial.

The role of the online teacher in supporting student learning: A case study

As teaching and learning environments for many tertiary courses move to online delivery, it is important to ensure effective student learning is still taking place. This paper presents a review of the current literature on the roles of the teacher and e-tutor in e-learning environments. The research presented here is a case study of a wholly online course in which the role of the etutors was examined. This was achieved through analysis of their online interactions with students from two separate offerings of the course. The study found that in this environment the main role undertaken by all e-tutors was a managerial one. Differences were also noted between the roles undertaken by casual e-tutors and faculty staff.

Profile of a fully online unit in an Australian arts and education faculty

Australia's leading distance education provider, Deakin University, has a policy to ensure all graduates in most courses must successfully complete at least one wholly online unit. Historically, all distance education at Deakin University has been undertaken solely in print. Off-campus students normally receive a Set Text, a series of additional photocopied readings and a Study Guide providing assistance on how to navigate through each weekly topic. Some fully online units currently offered by the University replicate this approach, ever though a distinct pedagogy is needed to ensure wholly online units truly enhance student learning.

This paper outlines the approach we adopted in developing AIX 391 - Work Transitions in the 2Ist Century, a wholly online unit designed to improve the capacity of Arts and Education students to identify viable career paths after they have graduated, The paper outlines the unit's rationale and development over a two-year period in adopting a student-centred approach to enhance teaming outcomes, while exposing students to new and often challenging online technologies. The paper also highlights results from the Student Evaluation of Teaching and Learning surveys, which ranked the unit in the top 5% of all Arts and Education faculty units offered in Semester 2, 2008.

Using an online simulation to address equity issues for off-campus students

The Middle East Politics Simulation (MEPS) is an online role-play exercise aimed at providing students with an improved level of understanding of the political dimensions of the Middle East, including the complexities of negotiation and decision making that face actors in this turbulent region. An online version of MEPS has been running since 1993, initially from Macquarie University, and since 2008 from Deakin University. This longevity provides a useful longitudinal perspective on utilising a collaborative online workplace to offer enhanced learning outcomes in the study of a political topic. The wholly online nature of the simulation means that students of all study modes and even different institutions can participate and benefit equally, thus negating some of the disadvantages faced by off-campus students in learning and assessment. Additionally, the student experience and depth of learning provided by the simulation constitute an excellent example of using the strengths of an e-learning environment to offer an alternative method of engaging and assessing students, which may be beneficial for accommodating the needs of those with differing learning styles.

Online delivery models: students’ perspectives

The optimal delivery model for units always puzzle curriculum designers and lecturers, particularly when the unit is offered in the summer trimester and students have greater choice as to whether to enrol in a unit or not. An ongoing research project in the School of Architecture and Built Environment at Deakin University aims to understand students’ perceptions on unit delivery in the summer trimester in order to improve support for online delivery models. The five delivery models in the study ranged from ‘traditional’ i.e. on campus lectures and tutorials for each week of the trimester; to ‘wholly online’ i.e. learning materials and communications entirely through the web-based student portal. Students rated their preferences for the five delivery models with additional comments. Students overwhelmingly prefer wholly online delivery during the summer trimester despite the benefits of other delivery models and that wholly online delivery may not offer their preferred learning experience. The students’ primary need is for flexibility which can be at odds with their equal need for interaction with academics and peers. It is important that academics recognise students’ perspectives to ensure their design of online delivery models improves teaching and learning in the summer trimester.

Sensitive Questions in Online Surveys: An Experimental Comparison of the RRT and the Crosswise Model

Self-administered online surveys provide a higher level of privacy protection to respondents than surveys administered by an interviewer. Yet, studies show that asking sensitive questions is problematic also in self-administered mode. Because respondents might not be willing to reveal the truth and provide answers that are subject to social desirability bias, the validity of prevalence estimates of sensitive behaviors gained via online surveys can be challenged. A wellknown method to combat these problems is the Randomized Response Technique (RRT). However, convincing evidence that the RRT provides more valid estimates than direct questioning in online mode is still lacking. Moreover, an alternative approach called the Crosswise Model (CM) has recently been suggested to overcome some of the deficiencies of the RRT. We therefore conducted an experimental study in which different implementations of the RRT and the CM have been tested and compared to direct questioning. Our study is a large-scale online survey on sensitive behaviors by students such as cheating in exams and paper plagiarism. The results of the study reveal poor per-formance of the RRT, while the CM yielded significantly higher estimates of sensitive behaviors than direct questioning. We conclude that the CM is a promising approach for asking sensitive questions in self-administered surveys.

Moreover, an alternative approach called the Crosswise Model (CM) has recently been suggested to overcome some of the deficiencies of the RRT. In the context of an online survey on plagiarism and cheating on exams among students of two Swiss universities (N = 6,494), we tested different implementations of the RRT and the CM and compared them to direct questioning using a randomized experimental design. Results reveal a poor performance of the RRT, which failed to elicit higher prevalence estimates than direct questioning. Using the CM however, significantly higher prevalence estimates were obtained making it a promising new alternative to the conventional RRT.

Combination of Kalman filter and least error square techniques in power system

An algorithm based on the concept of combining Kalman filter and Least Error Square (LES) techniques is proposed in this paper. The algorithm is intended to estimate signal attributes like amplitude, frequency and phase angle in the online mode. This technique can be used in protection relays, digital AVRs, DGs, DSTATCOMs, FACTS and other power electronics applications. The Kalman filter is modified to operate on a fictitious input signal and provides precise estimation results insensitive to noise and other disturbances. At the same time, the LES system has been arranged to operate in critical transient cases to compensate the delay and inaccuracy identified because of the response of the standard Kalman filter. Practical considerations such as the effect of noise, higher order harmonics, and computational issues of the algorithm are considered and tested in the paper. Several computer simulations and a laboratory test are presented to highlight the usefulness of the proposed method. Simulation results show that the proposed technique can simultaneously estimate the signal attributes, even if it is highly distorted due to the presence of non-linear loads and noise.
