Perceptions of roles and responsibilities in online learning : a case study

The extensive introduction of online technologies to support teaching and learning is impacting how teachers teach and students learn. It is also affecting both teaching staff’s and students’ perceptions of what each others’ roles are. The research reported here is part of a larger study that explored different aspects of teaching and learning in online environments. This study was undertaken within an Australian university and involved an institution-wide survey of students. The paper reports on students’ perceptions of their roles as online learners and the expectations they have of online teachers. The outcomes of the research suggest that different cohorts of students have different expectations. These expectations are informed by their mode of study and also by their perceptions of how staff engage with online teaching. Recommendations include proactive management of student expectations by staff, as well as a commitment by staff to meet those expectations.

Role play in blended learning : a case study exploring the impact of story and other elements

Role play is an increasingly popular technique in tertiary education, being student centred, constructivist and suitable for a range of subject areas. The choice of formats is wide open, with options ranging from the traditional face to face performance through to multi-user online computer games. Some teachers prefer to take advantage of features of both online and face to face formats and offer a blended form. This case study describes an innovative blended role play in which the online component plays a small but important part. The findings show that decisions on not only how to make the best use of technology but also how to design and facilitate a role play can have a profound effect on the creation of an engaging first-person story from which powerful learning can be drawn—in this case, learning outcomes including deep insights into strengths and weaknesses of participants' personal change management styles.

Enriching student experience and inter-professional learning of inclusive design with Second Life

This position paper reflects rapid advances in immersive 2D and 3D eLearning technologies and the expanding pool of ideas and applications in higher education across two professions. Inspiration has been drawn from examples in design learning, and various multidisciplinary collaborative projects through developmental research in Multi-User Virtual Environments (MUVEs). Linden Lab's Second Life (SL) is the most mature and popular of the ‘persistent’ virtual worlds. The study described in this paper aims to increase the authenticity of student learning through a range of SL simulated ‘life experiences’ relating to accessibility and mobility in the built environment. Significantly, the successes of such initiatives lie in several elements: teaching champions with vision and courage; detailed scripting of precise role-play encounters for first-time users to provide supportive ‘blended learning’ contexts; careful and vigilant strategic management of facilities and resources, and a robust design program. This paper focuses on the crucial alignment of these elements to the specific challenges of designing and navigating conception and development processes, to enable the execution and delivery of a tightly defined script for meaningful and memorable learning outcomes. This innovative pedagogical approach lacks time-tested outcomes, but is recognised equally as opportunity and challenge; risk and reward.

The impact of learning in the workplace policy on differing ICT degrees

At Victoria University, the release of a new Learning in the Workplace and Community (LiWC) policy has been introduced to ensure that graduates are job and career ready. The policy underlines the importance of workplace contextual learning in all course deliveries and is scheduled for progressive implementation by 2010. For each degree, the policy mandates that a minimum of 25% of program content and assessment must be related to work integrated learning.

Compliance with the 25% shift poses significant challenges for its implementation upon all undergraduate programs since the policy is expected to impact upon program structures, unit deliveries, assessment practices, and course administrations. In particular, there has been an extensive review of existing approaches to learning and teaching in the programs that deliver information and communications technology (ICT) degrees across business and science faculties. This paper describes the current Bachelor of Science in Computer Science and Bachelor of Business in Information Systems programs identifying similarities and differences between the two offerings with respect to their learning in workplace components. It explores possible synergies between the two programs that could be capitalized upon to implement the LiWC policy and details the challenges to both faculties in mounting a coordinated response.

Splash!: a prospective birth cohort study of the impact of environmental, social and family-level influences on child oral health and obesity related risk factors and outcomes

Background: Dental caries (decay) is the most prevalent disease of childhood. It is often left untreated and can impact negatively on general health, and physical, developmental, social and learning outcomes. Similar to other health issues, the greatest burden of dental caries is seen in those of low socio-economic position. In addition, a number of diet-related risk factors for dental caries are shared risk factors for the development of childhood obesity. These include high and frequent consumption of refined carbohydrates (predominately sugars), and soft drinks and other sweetened beverages, and low intake of (fluoridated) water. The prevalence of childhood obesity is also at a concerning level in most countries and there is an opportunity to determine interventions for addressing both of these largely preventable conditions through sustainable and equitable solutions. This study aims to prospectively examine the impact of drink choices on child obesity risk and oral health status.
Methods/Design: This is a two-stage study using a mixed methods research approach. The first stage involves qualitative interviews of a sub-sample of recruited parents to develop an understanding of the processes involved in drink choice, and inform the development of the Discrete Choice Experiment analysis and the measurement instruments to be used in the second stage. The second stage involves the establishment of a prospective birth cohort of 500 children from disadvantaged communities in rural and regional Victoria, Australia (with and without water fluoridation). This longitudinal design allows measurement of changes in the child’s diet over time, exposure to fluoride sources including water, dental caries progression, and the risk of childhood obesity.
Discussion: This research will provide a unique contribution to integrated health, education and social policy and program directions, by providing clearer policy relevant evidence on strategies to counter social and environmental factors which predispose infants and children to poor health, wellbeing and social outcomes; and evidence-based strategies to promote health and prevent disease through the adoption of healthier lifestyles and diet. Further, given the absence of evidence on the processes and effectiveness of contemporary policy implementation, such as community water fluoridation in rural and regional communities it’s approach and findings will be extremely
informative.

Learning through constructing representations in science : a framework of representational construction affordances

Compared with research on the role of student engagement with expert representations in learning science, investigation of the use and theoretical justification of student-generated representations to learn science is less common. In this paper, we present a framework that aims to integrate three perspectives to explain how and why representational construction supports learning in science. The first or semiotic perspective focuses on student use of particular features of symbolic and material tools to make meanings in science. The second or epistemic perspective focuses on how this representational construction relates to the broader picture of knowledge-building practices of inquiry in this disciplinary field, and the third or epistemological perspective focuses on how and what students can know through engaging in the challenge of representing causal accounts through these semiotic tools. We argue that each perspective entails productive constraints on students’ meaning-making as they construct and interpret their own representations. Our framework seeks to take into account the interplay of diverse cultural and cognitive resources students use in these meaning-making processes. We outline the basis for this framework before illustrating its explanatory value through a sequence of lessons on the topic of evaporation.

Comparison of the traditional problem-based learning format and larger, directed, independent study groups

 Problem based learning has been implemented as a pedagogical tool world-wide across a range of health professions since its inception at McMaster University, Canada, in 1969 (Neville & Norman, 2007). In addition to enhancing knowledge and understanding it is also claimed that PBL develops communication skills, encourages teamwork, sharing of information and respect for others, furthers problem solving skills, and allows students to assume responsibility for their own learning (Wood, 2003). However, the cognitive outcomes of PBL and traditional pedagogy (based on didactic teaching) are similar and hence widespread adoption of PBL has been questioned (see Colliver, 2000). Criticisms of PBL include its resource hungry nature, requiring, as it does, experienced tutors to facilitate .learning across several clusters of students dealing with the same problem. Given the actual and anticipated increase in numbers of medical students in Australia other strategies that retain the advantages of PBL, while minimising the demands on faculty, should now be explored. This paper reports our experience with a modification of the traditional PBL approach, termed PBLplus. This innovation was trialled in a regional clinical school, attached to a hospital, with a group of 19 graduate entry students, who had completed an integrated Year 1 / 2 of the MBBS. PBLplus involved allocating students from the whole class to three task directed groups. Groups had specified assignments to complete to facilitate learning across the whole class. A tutor listened to student presentations and provided an interactive presentation. Hence use of tutors was made more efficient, and faculty input was more specialised.

Analysis of asynchronous online discussion forums for collaborative learning

Online discussion forums are well suited for collaborative learning systems. Much of the currently available research indicates that effectively designed collaborative learning systems motivate and enhance learning experiences of the participants which in turn lead to enhanced learning outcomes. This paper develops taxonomy of the asynchronous online discussion forums with the aims of increasing the understanding and awareness of various types of asynchronous discussion forums. The taxonomy is framed by constructivist pedagogical principles of asynchronous online discussion forum. The key attributes of online discussions and the factors influencing the discussion forum’s design are identified. The taxonomy will help increase the online course designers’ ability to design more effective learning experiences for student success and satisfaction. It will also help researchers to understand the various features of the asynchronous discussion forums. The article concludes with implications for pedagogy and suggestions for the direction of future theoretical and empirical research.

Evaluation of delivery of the switched on secondary science professional learning (SOSSPL) program

The Switched On Secondary Science Professional Learning (SOSSPL) program consisted of three days professional learning. Days 1 and 2 were undertaken consecutively, with Day 3 following a break of several weeks. The break allowed sufficient time for teachers to undertake a small classroom-based project within one of the topics teachers will be teaching at the time. The program was designed to build teacher capacity to improve learning outcomes in secondary science.

Evaluation of delivery of the switched on secondary science professional learning (SOSSPL) program (2011-12)

The Switched On Secondary Science Professional Learning (SOSSPL) program consisted of three days professional learning for Victorian DEECD secondary science teachers. Days 1 and 2 were undertaken consecutively, with Day 3 following a break of several weeks. The break allowed sufficient time for teachers to undertake a small classroom-based project within one of the topics they were teaching at the time. The program was designed to build teacher capacity to improve student learning outcomes in secondary science.

The program supported teachers to plan and implement classroom sequences that focused on student construction and interpretation of different representations of the science concepts and processes that are described by the Victorian Essential Learning Standards (VELS): Science and the Science Continuum P-10. The Deakin University team in collaboration with the Department of Education and Early Childhood Development (DEECD) produced curriculum resources for the program that encapsulated a representational focus to the teaching and learning of science. The program explored and linked to core DEECD resources such as the e5 Instructional Model and the Science Continuum P-10.
The SOSSPL program was delivered in all Victorian DEECD regions in 2010-11 and was evaluated (Hubber et al, 2011). The program was delivered again in all Victorian DEECD regions in 2011-12. The evaluation of the 2011-12 program is reported here with some comparisons made to the findings from the previously delivered program.
This evaluation of the SOSSPL program involved an online survey, daily workshop evaluations, focus group and presentations data of the participating teachers’ classroom-based projects. The aim of the evaluation was to make a judgement about the effectiveness of the SOSSPL program in terms of building teacher capacity to improve student learning outcomes in secondary science.

Development and evaluation of a teaching and learning approach in cross-cultural care and antidiscrimination in university nursing students

Background:
Cross-cultural care and antidiscrimination are vital to ethical effective health systems. Nurses require quality educational preparation in cross-cultural care and antidiscrimination. Limited evidence-based research is available to guide teachers.

Objectives:
To develop, implement and evaluate an evidence-based teaching and learning approach in cross-cultural care and antidiscrimination for undergraduate nursing students.

Design:
A quantitative design using pre- and post-survey measures was used to evaluate the teaching and learning approach.

Settings:
The Bachelor of Nursing program in an Australian university.

Participants:
Academics and second year undergraduate nursing students.

Methods:
A literature review and consultation with academics informed the development of the teaching and learning approach. Thirty-three students completed a survey at pre-measures and following participation in the teaching and learning approach at post-measures about their confidence to practice cross-cultural nursing (Transcultural Self-efficacy Tool) and about their discriminatory attitudes (Quick Discrimination Index).

Results:
The literature review found that educational approaches that solely focus on culture might not be sufficient in addressing discrimination and racism. During consultation, academics emphasised the importance of situating cross-cultural nursing and antidiscrimination as social determinants of health. Therefore, cross-cultural nursing was contextualised within primary health care and emphasised care for culturally diverse communities. Survey findings supported the effectiveness of this strategy in promoting students' confidence regarding knowledge about cross-cultural nursing. There was no reported change in discriminatory attitudes. The teaching and learning approach was modified to include stronger experiential learning and role playing.

Conclusions:
Nursing education should emphasise cross-cultural nursing and antidiscrimination. The study describes an evaluated teaching and learning approach and demonstrates how evaluation research can be used to develop cross-cultural nursing education interventions.

Understanding the balance of experienced teachers' ICT learning

In the Information Age, ICT learning requires a balance between the concrete and experiential learning process and the abstract conceptualisation of Andragogy. Future Teacher Professional Development will need to understand the complexities of the concrete experience and the abstract conceptualisation of new knowledge. Professional Development will need to comprehend how experienced teachers as digital immigrants learn. It will further need to understand what abilities are essential for these experienced teachers and how they develop an awareness of their ICT learning. This paper will examine a study that was undertaken with a group of Post Registration Primary School Educators. These experienced teachers undertook the Post Registration or fourth year of their Bachelor of Education (Primary) course at an Australian Educational Institute. These experienced teachers with limited ICT exposure went through an ICT learning process over a period of one year. They finally acquired the ICT knowledge and skills, however within the time span of one year, theoretical pedagogy was absent or minimal.

Classification of electrocardiogram and auscultatory blood pressure signals using machine learning models

In this paper, two real-world medical classification problems using electrocardiogram (ECG) and auscultatory blood pressure (Korotkoff) signals are examined. A total of nine machine learning models are applied to perform classification of the medical data sets. A number of useful performance metrics which include accuracy, sensitivity, specificity, as well as the area under the receiver operating characteristic curve are computed. In addition to the original data sets, noisy data sets are generated to evaluate the robustness of the classifiers against noise. The 10-fold cross validation method is used to compute the performance statistics, in order to ensure statistically reliable results pertaining to classification of the ECG and Korotkoff signals are produced. The outcomes indicate that while logistic regression models perform the best with the original data set, ensemble machine learning models achieve good accuracy rates with noisy data sets.

Improving laboratory learning through self and peer assessment of laboratory reports

The laboratory provides an opportunity for students to achieve many learning outcomes including to critically evaluate information, interpret and draw conclusions from scientific data, and communicate scientific results, information, or arguments. This paper describes a laboratory-writing task that involves self and peer evaluation. After discussion of the expectations of laboratory report writing during class, students self and peer evaluate reports. In a process similar to double-blind journal refereeing, students practise critically evaluating the quality of academic writing using a rubric. The summative assessment is based on how consistent their evaluations are with the evaluations of the same reports performed by their peers. The formative assessment is that students receive peer evaluations and feedback via a rubric on reports that they have written. The skill of critically evaluating their own reports is used to improve the laboratory reports in subsequent assessment tasks.

The role of the facilitator in a project/design based learning environment

The Project Oriented Design Based Learning (PODBL) is a teaching and learning approach (TLA) that is based on engineering design activities undertaken during a project. PODBL encourages independent learning and a deep approach to student learning outcomes. The Centre for Advanced Design in Engineering Training (CADET) is a new engineering building with cutting edge technology facilities at Deakin University. It acts as a catalyst for a pedagogical change in the way that Engineering is delivered. This paper is focused on the role of the facilitator in a project/design based learning environment and it also looks in to appropriate staff development training for a project/design based learning environment.
