Using web-based mathematical interactive exercises and exploratory investigations : the possibilities and pitfalls

This case study looks at how a teacher used interactive exercises and exploratory investigations to reinforce concepts that have been learnt in a Year 8 Mathematics class. It highlights the practical problems faced by the teacher in terms of technical issues such as slow download times and logging on problems as well as class management issues. The findings are discussed in the light of the teacher’s mediation with the affordances of the Internet.

Supporting knowledge transfer in web-based managed IT support

Purpose – The purpose of this paper is to highlight the importance and complexities of the knowledge transfer process in the provision of effective managed after-sales IT support, when the web is used for service delivery.

Design/methodology/approach – The paper features an interpretive case study of a multinational Managed Service Provider (MSP) and a focus group of representatives from five comparable MSPs.

Findings – The paper finds that MSPs that use web-based channels for the provision of after-sales IT support services need to address a range of important social and organisational issues in order to realise cost and efficiency-based benefits.

Research limitations/implications – The paper provides a four stage processual model of knowledge transfer in the provision of web-based managed after-sales IT support services. The barriers and enablers of knowledge transfer at each stage are identified. The paper adopts a MSP perspective and suggests that further research from the customer perspective is required.

Practical implications – The paper highlights some important social and organisational enablers and barriers, which will guide MSPs when providing managed after-sales IT support using webbased channels.

Originality/value – The paper provides the first staged model of inter-organisational knowledge transfer in a complex multi-organisational and multi-channel web-based context.

Preparing pre-service physical education teachers for uncertain future(s) : a scenario-based learning case study from Australia

Background: A key aim of a physical education teacher education (PETE) program is to promote wide and deep knowledge, enabling students to establish connections and understand contexts within and beyond education, physical education and their life worlds. Most often PETE programs equip students with content knowledge and pedagogical strategies that help them address current challenges, but less attention is directed to helping the students anticipate future challenges and engage with opportunities they may face as teachers.
Purpose: This paper presents a case study of scenario-based learning as it was implemented in a final year PETE program in an Australian university, as a means of preparing students for their future teaching careers.
Participants and setting: Twenty-five final year pre-service physical education teachers enrolled in the culminating unit of their physical education degree.
Data collection: Scenario-based learning was introduced to the students via class discussion and assigned tasks. Examples of student-written scenarios and reflection on the experience from the lecturer and student perspectives are analysed.
Findings: Although the cohort found the process of scenario-based learning daunting the post-unit questionnaires revealed that it was a valued and valuable means of exploring professional issues they will face in the future. Scenario-based learning was a powerful tool of learning as well as modelling a pedagogy students could use in the upper levels of secondary school.
Conclusion: This paper argues that scenario-based learning should be a key component of forward-looking PETE programs that encourage their graduates to solve problems about issues they may face as beginning teachers.

Blended learning in finance : comparing student perceptions of lectures, tutorials and online learning environments across different year levels

In modern pedagogy, a blended approach is used comprising both face-to-face and online learning. This study investigates how undergraduate students majoring in finance view the different learning environments, and evaluates the changes in perception over the three years of the degree after controlling for gender, age, international/domestic student and English as a first language. Using a purpose designed survey instrument, students across the three years of undergraduate study rated the importance of lectures, tutorials and web-based learning environments in a blended learning model. The results indicate that there is still a strong preference for face-to-face learning. Additionally, there were significant differences in attitudes and perception by year level.

An evaluation of a project-based learning initiative in engineering education

Project-based learning (PBL) is a well-known methodology for engineering design education due to a number of benefits it is claimed to offer. This paper presents the initial offering of a first-year engineering PBL unit at Griffith University in Australia. An evaluation of student perceptions of the unit revealed that students generally enjoyed the experience, with the oral presentation aspect receiving the lowest satisfaction rating. There was no significant difference in the ratings between any demographic grouping, suggesting that all students were able to participate in, and experience, the unit in essentially the same way. The best aspects of the unit and those aspects needing improvement were similar to the findings of other investigations documented in the literature. It is proposed that future offerings of the unit will reduce the number of design projects from three to two per semester and will attempt more sophisticated individualisation of marks for group work activities.

An assessment of game based learning

‬This thesis uses the principles arising from both the literature review and surveys and experiements to further the understanding of game design that supports quality learning. These principles have been used to build two exemplar platforms that on a number of criteria and measures, represent generic principles concerning game-based learning.

(Dis)ordering teacher education : from problem students to problem-based learning

This paper takes issue with the 'disabling' of students enrolled in teacher education courses, perpetrated by definitions of students' learning disorders and by the structures and pedagogies engaged by teacher educators. Focusing on one case, but with relevance for similarly affected systems, the paper begins by outlining the changed student entry credentials of Australian universities and their faculties of education. These are seen as induced by a shift from elite to mass provision of higher education and the particular effect on teacher education providers (especially those located in regional institutions) of the politics of government funding and the continuing demand for teachers by education systems. While these changed conditions are often used to argue an increased university population of students with learning disorders, the paper suggests that such arguments often have more to do with how student problems are defined by institutions and how these definitions serve to secure additional government funding. More pertinently, the paper argues that such definition tends to locate the problem in individual students, deferring considerations of teacher educators' pedagogy and the learning arrangements of their institutions. The paper concludes that the place to begin addressing these issues of difficulty would seem to be with a different conception of knowledge production.

A new sliding mode-based learning control scheme

 A new sliding mode-based learning control scheme for a class of SISO dynamic systems is developed in this paper. It is seen that, based on the most recent information on the closed-loop stability, a recursive learning chattering-free sliding mode controller can be designed to drive the closed-loop dynamics to reach the sliding mode surface in a finite time, on which the desired closed-loop dynamics with the zero-error convergence can be achieved.

Web-based mathematics : some 'dos' and 'don’ts'

This case study describes an “out of field” teacher’s use of the Internet to teach a range of mathematical topics in a modified Year 8 mathematics class. It highlights the importance of three factors for implementing a discernible web-based teaching strategy: appropriate choice of web objects,effective “virtual” pedagogy, and technical support and expertise. Based on these findings, a framework is suggested for constructing an effective teaching strategy to support the use of virtual resources in the actual mathematics classroom.

Learning cultures of problem-based learning teams

The learning experiences of first-year engineering students to a newly implemented engineering problem-based learning (PBL) curriculum is reported here, with an emphasis on student approaches to learning. Ethnographic approaches were used for data collection and analysis. This study found that student learning in a PBL team in this setting was mainly influenced by the attitudes, behaviour and learning approaches of the student members in that team. Three different learning cultures that emerged from the analysis of eight PBL teams are reported here. They are the finishing culture, the performing culture and the collaborative learning culture. It was found that the team that used a collaborative approach to learning benefited the most in this PBL setting. Students in this team approached learning at a deep level. The findings of this study imply that students in a problem-based, or project-based, learning setting may not automatically adopt a collaborative learning culture. Hence, it is important for institutions and teachers to identify and consider the factors that influence student learning in their particular setting, provide students with necessary tools and ongoing coaching to nurture deep learning approaches in PBL teams.

Reliable aggregation on network traffic for web based knowledge discovery

The web is a rich resource for information discovery, as a result web mining is a hot topic. However, a reliable mining result depends on the reliability of the data set. For every single second, the web generate huge amount of data, such as web page requests, file transportation. The data reflect human behavior in the cyber space and therefore valuable for our analysis in various disciplines, e.g. social science, network security. How to deposit the data is a challenge. An usual strategy is to save the abstract of the data, such as using aggregation functions to preserve the features of the original data with much smaller space. A key problem, however is that such information can be distorted by the presence of illegitimate traffic, e.g. botnet recruitment scanning, DDoS attack traffic, etc. An important consideration in web related knowledge discovery then is the robustness of the aggregation method , which in turn may be affected by the reliability of network traffic data. In this chapter, we first present the methods of aggregation functions, and then we employe information distances to filter out anomaly data as a preparation for web data mining.

A longitudinal evaluation of a project-based learning initiative in an engineering undergraduate programme

Project-based learning (PBL) is a well-known student-centred methodology for engineering design education. The methodology claims to offer a number of educational benefits. This paper evaluates the student perceptions of the initial and second offering of a first-year design unit at Griffith University in Australia. It builds on an earlier evaluation conducted after the initial offering of the unit. It considers the implementation of the recommended changes. Evaluations of the two offerings reveal that students (in both the initial and second offering) generally enjoyed the experience, but that the second offering was found to be a significantly more enjoyable learning experience. Students in the second offering also reported a significantly better understanding of what they needed to do for the design projects and where to find the requisite information. The oral presentation aspect of the initial and second offerings received the lowest satisfaction rating. The inclusion (and delivery) of the computer-aided drawing component of the unit is seen as a positive aspect by some students, but many others comment on it negatively. The best aspects of the PBL unit and those aspects needing further improvement were similar to the findings of other investigations documented in the literature.

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.
