The graphic calculator as a thinking tool : perspectives from the classroom

For over a decade, the graphic calculator has been promoted not only as a computational tool, but also as a thinking tool - for example, as an aid to enhance conceptual understanding, as a problem-solving tool and as a means of enabling students to engage in meaningful investigations. However, research studies focusing on these aspects have shown mixed results and have mostly focused on graphs and functions.

This paper reports on one aspect of a case study in a year 10 mathematics classroom - the role of the graphic calculator as a thinking tool. Data from observations of nine statistics lessons and interviews with the teacher and five students, are analysed from three perspective's: the teacher's intentions with respect to the use of the graphic calculator as a tool to promote conceptual understanding as opposed to procedural competence; the opportunities afforded during the lessons for student investigation; and students' views of how the graphic calculator enhanced conceptual understanding.

The results provide insights into ways in which students perceive the graphic calculator as promoting conceptual understanding, as well as some of the difficulties encountered in practice in a classroom where the teacher clearly intends to use the graphic calculator as a thinking tool.

Towards a framework for exploring children's analytical thinking and creativity in technology

Technology education provides children with opportunities to be creative as they engage in problem solving and make products that address human needs. When thinking creatively, children generate new ideas through remote associations and brainstorming and this type of thinking is enhanced when attention is allowed to wander in a relaxed and uncompetitive environment. Research shows that the two mental states (generative and nongenerative/analytical) cannot exist simultaneously (Howard-Jones 2002). It follows that at some point in the technological process a child’s generative mental state needs to give way to a nongenerative, analytical state so that the child can focus on analysing information. This research project aims to investigate the impact of analytical thinking on creativity in the context of technology education in young children.

Problematising the mathematics curriculum : some examples from Australia and Japan

Problem solving is often seen as being the core of mathematics. While there are many examples of teaching for and about problem solving, there are relatively few examples of teaching mathematical content through problem solving. This paper uses data from three, apparently quite different, mathematics lessons from Australia and Japan to explore different ways in which mathematics can be taught successfully through problem solving and to analyse some of the characteristics of such lessons. It also attempts to identify some of the supports and constraints for adopting a problem solving approach to the teaching of mathematics that exist in the quite different contexts of Japan and Australia.

Framework for understanding creativity in requirements engineering

Creativity is important in the discovery and analysis of user and business requirements to achieve innovative uses of information and communication technologies. This paper builds a theoretical framework for understanding creativity in requirements engineering. The framework provides a systematic means of understanding creativity in requirements engineering and comprises five elements (product, process, domain, people and socio-organisational context). The framework provides researchers with a sound basis for exploring how the five elements of creativity can be incorporated within RE methods and techniques to support creative requirements engineering. It provides practitioners with a systematic means of creating environments that nurture and develop creative people, cognitive and collaborative processes and products.

A study of the concurrent execution of parallel and sequential applications on a non-dedicated cluster

Computers of a non-dedicated cluster are often idle (users attend meetings, have lunch or coffee breaks) or lightly loaded (users carry out simple computations to support problem solving activities). These underutilised computers can be employed to execute parallel applications. Thus, these computers can be shared by parallel and sequential applications, which could lead to the improvement of their execution performance. However, there is a lack of experimental study showing the applications’ performance and the system utilization of executing parallel and sequential applications concurrently and concurrent execution of multiple parallel applications on a non-dedicated cluster. Here we present the result of an experimental study into load balancing based scheduling of mixtures of NAS Parallel Benchmarks and BYTE sequential applications on a very low cost non-dedicated cluster. This study showed that the proposed sharing provided performance boost as compared to the execution of the parallel load in isolation on a reduced number of computers and better cluster utilization. The results of this research were used not only to validate other researchers’ result generated by simulation but also to support our research mission of widening the use of non-dedicated clusters. Our promising results obtained could promote further research studies to convince universities, business and industry, which require a large amount of computing resources, to run parallel applications on their already owned non-dedicated clusters.

Investigating children's languge in technology education

When undertaking design and technology activities, children are provided with opportunities to create solutions to problems in new and innovative ways. There have been few studies which have looked closely at how primary aged children undertake technology activities and even fewer that have investigated children's language when undertaking a technology task. This paper reports on a research project that focused on children's thinking and also the language that the children used when they were involved in a design and technology activity. The findings suggest that there were several key ideas that the children focused on: the fun of the activity, the satisfaction of completing the task, the difficulty of problem solving and the interest in creating something 'new'.

Group composition : influences of optimism and lack thereof

Lesson video and video-stimulated post-lesson interviews were used to study the role of optimism in collaborative problem solving in a Grade 5/6 classroom for the purpose of informing group composition. This study focuses on the activity of two students who differed on the personal characteristic 'optimistic orientation'. It examines how the presence or absence of an optimistic orientation to failures (Seligman, 1995) contributed to these students' interactions with their groups and opportunities for collaborative creation of new knowledge. One group collaborated to develop mathematical knowledge that was new to each group member and the other group did not. These findings raise questions about how to group students who are not yet optimistic to enable collaborative activity, and how to build optimism.

Interaction perspectives of individuals and destination marketing organizations in the tourism network of Australia

This paper seeks to assess the nature, perspectives and characteristics of interactions in the tourism network in Australia. The pattern of interactions between network participants is crucial in defining the network and its boundaries. Ford and Hakansson (2007) develop a structure of interactions between participants in a network. Time dimensions of the interactions are sequence, ordering and trajectory. Relativity dimensions are jointness, interdependence and heterogeneity. Interaction can be problem solving both incurring costs and producing benefits.
There are two stages of this research. The first stage obtained the perspectives from 35 organizations regarding the challenges facing tourism, key growth segments, brand and promotional strategies and customer insights and satisfaction levels. The second stage of this research uses follow up personal interviews and assesses the interaction patterns among network participants. The sequence, ordering and trajectory of the interactions are examined as are the jointness, interdependence and heterogeneity of the interactions. A network map is produced based on the frequency and importance of the communications and interactions. The research will also address key questions identified by Johnston, Peters and Gassenheimer (2006). Is the network characterized by tighter or looser coupling? How important is collaboration to the survival (or success) of each participant?

Changes in quality of life and coping among people with multiple sclerosis over a 2 year period

There is a need to investigate the impact of different coping strategies on quality of life (QOL) of people with multiple sclerosis (MS), in order to better inform intervention programs for this population. This study evaluated the relationship between QOL and coping over a 2 year period among people with MS. Participants were 382 people with MS (144 male, 238 females) and 291 people without a neurological or other chronic illness from the general population (101 males, 190 females). People with MS experienced lower QOL than the control group in the domains of global QOL, independence, social and spiritual QOL scales, as well as the problem solving and social/emotional support coping scales. Interestingly, people with MS experienced higher psychological QOL than the general population, and higher detachment and focusing on the positive coping. Over time, people with MS demonstrated increases in their global QOL as well as in their social/emotional support coping. Women demonstrated higher levels than men of global QOL and Social/emotional support coping. The results of these findings have implications for information and intervention programs for people with MS.

Developing student transferable skills through reflective porfolios

The development of transferable skills in students, ie those relevant to any future employment, is a common goal of degree programmes. Reflection is a mechanism frequently used in the training of medical and teaching professionals to develop self-awareness of personal skills levels that enable participants to become self-reflective practitioners. The intention in this research was to trial reflection for construction management and architecture students through a series of interventions to engage students in the explicit development of transferable skills and self-awareness. Students were required to keep a ‘diary’ or journal under specific skills headings: communication (involving active listening, conflict resolution, negotiation), team building, problem solving, report writing and presentation skills based on their experiences at university, work and in social situations. A range of learning resources were made available to assist students. The journals were analysed according to a recognised coding for the depth of their reflection . At the end of the semester, students were required to “apply” for a job description that required explication of the knowledge and skills that were intended to be further developed during the unit. In practice, few students appreciated the journaling and some were even hostile to the process, but all students demonstrated good appreciation of their abilities and skills in the job application – essentially a mechanism that required reflection. In conclusion, explicit reflection through journaling is not a universally popular practice, but tasks that appear to have some foundation in practicality that require reflection are more likely to be appreciated. Students depth of reflection was found to improve through practice.

Beating the blues after cancer : randomised control trial of a tele-based psychological intervention for high distress patients and carers

Background : The diagnosis and treatment of cancer is a major life stress such that approximately 35% of patients experience persistent clinically significant distress and carers often experience even higher distress than patients. This paper presents the design of a two arm randomised controlled trial with patients and carers who have elevated psychological distress comparing minimal contact self management vs. an individualised tele-based cognitive behavioural intervention.

Methods/design : 140 patients and 140 carers per condition (560 participants in total) will been recruited after being identified as high distress through caller screening at two community-based cancer helplines and randomised to 1) a single 30-minute telephone support and education session with a nurse counsellor with self management materials 2) a tele-based psychologist delivered five session individualised cognitive behavioural intervention. Session components will include stress reduction, problem-solving, cognitive challenging and enhancing relationship support and will be delivered weekly. Participants will be assessed at baseline and 3, 6 and 12 months after recruitment. Outcome measures include: anxiety and depression, cancer specific distress, unmet psychological supportive care needs, positive adjustment, overall Quality of life.

Discussion : The study will provide recommendations about the efficacy and potential economic value of minimal contact self management vs. tele-based psychologist delivered cognitive behavioural intervention to facilitate better psychosocial adjustment and mental health for people with cancer and their carers.

Experience with practical project based learning in a developing undergraduate engineering degree program

The use of practical learning experience in undergraduate degree programs offers students the opportunity to apply their knowledge and receive feedback in a supportive environment before entering the workplace or undertaking further study. Traditional laboratory based instruction allows students this opportunity; however, it tends to provide limited opportunity for students to explore creative solutions to problem solving. The University of Waikato recently established undergraduate degree programs in engineering and has aimed to incorporate flexible learning opportunities for students, as part of their degree and as extra-curricular activities. This paper presents some of the practical project based opportunities that have been adopted and examines the role these have played in a developing engineering program.

Phenomenological inquiry into the experience of web project managers

The advent of the Internet and the World Wide Web has been instrumental in bringing about the growth in the implementation of web-based information systems (WBIS). Such systems are designed with the aim of improving productivity, data accuracy, and the reduction of paperwork and administrative overheads. Moreover, unlike their conventional non-web-based predecessors, the WBIS are commonly aimed at users who are casual and untrained, geographically distributed and non-homogenous. The dissemination of WBIS necessitates additional infrastructure support in the form of a security system, workflow and transaction management, and web administration. WBIS are commonly developed using an evolutionary approach, whereby the version of the application, acquired from the vendor, is first deployed as a pilot, in order to gather feedback from the target users before the evolutionary cycles commence. While a number of web development methodologies have been proposed by existing research, there is a dearth of empirical evidence that elucidates the experiences of project initiators in pursuing the evolution of web services, a process that undoubtedly involves dealing with stakeholder issues. This research project presents a phenomenological investigation of the experiences of project managers with the implementation of web-based employee service systems (ESS), a domain that has witnessed a sharp growth in Australia in recent times. However, the project managers’ rich, multidimensional account of their experiences with the implementation of ESS revealed the social obstacles and fragility of intra-organizational relationships that demanded a cautious and tactful approach. Thus, the study provides a socio-organizational perspective to web projects in contrast to the functionalist paradigm of current web development methodologies. The research also confirms that consideration of the concerns of stakeholders by project managers is crucial to the successive cycles of ESS evolution. Project managers address stakeholder concerns by pursuing actions that are aimed at encouraging ESS usage, but at the same time, such actions can have consequences necessitating subsequent iterations of system enhancement and improvement. Finally, the research also discovered that despite the different socio-political climate prevalent in various organizations, in which ESS are being implemented, the experiences of project managers in dealing with stakeholder concerns can be captured and independently confirmed in terms of their perceived relevance and usefulness in problem-solving within the application domain.

Investigation into the skill levels achieved by mathematics students in the V.C.E. and the H.S.C. mathematics courses

This study examines whether recent changes to the mathematics courses offered in the final year of secondary school (Year 12) in the state of Victoria, Australia have affected the learning outcomes of students in terms of then: skill levels in algebra, calculus and problem solving; and in terms of their preparation for a tertiary mathematics unit. The impact of these changes on the transition from secondary to tertiary mathematics is also considered. A comparison is made between students who attempted a first year mathematics unit at the University of Melbourne (U. of M.) having completed the new V.C.E. (Victorian Certificate of Education) mathematics courses and mathematics courses from the previous H.S.C. (Higher School Certificate) system. The comparison involves the use of tests administered upon entrance to a tertiary mathematics unit at the U. of M., and questionnaires. In 1991, V.C.E, students and H.S.C. students attempted the same mathematics test at the U. of M. and their results were compared. In 1992, the tests were attempted by V.C.E. students only. To compare new V.C.E. students and H.S.C. students, questions on the 1991 test were matched with similar questions on the 1992 tests and a panel of experts determined what the H.S.C. students who attempted the 1991 test would have been expected to average on these matched questions on the 1992 tests had they attempted them. These expected average scores were then compared with the actual scores of the new V.C.E. students. The scores of the groups were scaled when necessary. Questionnaires were administered to 1991 U. of M, mathematics students who were part of the V.C.E. pilot group in 1990, secondary mathematics educators, tertiary mathematics educators, and 1991 V.C.E. (1992 U. of M.) students. The mathematical misconceptions exhibited by new V.C.E. students are discussed and their frequencies stated. The research indicates that the new V.C.E. mathematics courses have provided the V.C.E. mathematics students in this study with significantly lower skill levels and a significantly poorer preparation for a tertiary mathematics unit than those which were previously provided by the H.S.C. mathematics courses.
