Webbing and orchestration. Two interrelated views on digital tools in mathematics education
The integration of digital tools in mathematics education is considered both
promising and problematic. To deal with this issue, notions of webbing and
instrumental orchestration are developed. However, the two seemed to be
disconnected, and having different cultural and theoretical roots. In this
article, we investigate the distinct and joint journeys of these two
theoretical perspectives. Taking some key moments in recent history as points
of de- parture, we conclude that the two perspectives share an importance
attributed to digital tools, and that initial differences, such as different
views on the role of digital tools and the role of the teacher, have become
more nuances. The two approaches share future chal- lenges to the organization
of teachers'collaborative work and their use of digital resources.Comment: Teaching Mathematics and its Applications (2014) to be complete
Devising a consensus definition and framework for non-technical skills in healthcare to support educational design: A modified Delphi study
Background
Non-technical skills are a subset of human factors that focus on the individual and promote safety through teamwork and awareness. There is no widely adopted competency or outcome based framework for non-technical skills training in healthcare outside the surgical environment. The authors set out to devise such a framework and reach a consensus on a definition using a modified Delphi approach.
Methods
An exhaustive list of published and team suggested items was presented to the expert panel for ranking and to propose a definition. In the second round, a focused list was presented, as well as the proposed definition elements. The finalised framework was sent to the panel for review.
Summary of results
16 experts participated (58% response rate). A total of 36 items of 105 ranked highly enough to present in round two. The final framework consists of 16 competencies for all and 8 specific competencies for team leaders. The consensus definition describes non-technical skills as ‘a set of social (communication and team work) and cognitive (analytical and personal behaviour) skills that support high quality, safe, effective and efficient inter-professional care within the complex healthcare system’.
Conclusions
The authors have produced a new competency framework, through the works of an international expert panel, which is not discipline specific. This consensus competency framework can be used by curriculum developers, educational innovators and clinical teachers to support developments in the field
English language readability task performance in a mobile setting - the effect of gender
Mobile computing has become very common in the present day fast changing technological development. It is expected that in future, people will be more mobile than today and all kinds of tasks that are performed in the stationary environment will be undertaken in a mobile environment also. As traffic on the road and also the population
are increasing at a very fast pace, the future generation will spend a lot of time in a mobile environment. Therefore, assessment of operators’ performance in a mobile setting will become all the more important. Mobile environment is influenced by vehicular vibration for all kinds of tasks. The present study made an attempt to explore the English language readability performance of a target group. Fourteen subjects (seven males and seven females) from an English language teaching institute were selected for this study. The base line value of reading speed was obtained on the basis of stationary environment
reading task performance. Reading speed was noted in the number of words read per minute (NWRPM). The same subjects were used for reading in the vibratory environment and difference in the performance was noticed. A stimulus was presented on a lap-top in both cases. Vibration was assessed on the basis of ISO 2631-1 (1997) guideline.
ANOVA statistical tool was used to analyze the data. The result indicated that the performance of operators was significantly affected due to the presence of vibration and

The role of user requirements research in medical device development
Aims and Objectives: This research aims to suggest a concise framework to help in the better
conceptualisation and integration of users in the medical device development (MDD) process. The
current economic, political and social climate concerning the matter of healthcare delivery has
resulted in the emergence of numerous users and user groups for whom the healthcare system has not
previously catered for. These users have created ambiguity for the designers and manufacturers of
medical devices as the boundaries between their needs and requirements have blurred, outdating
current methods of MDD to meet consumer needs.
Research Design and Methodology: The research methodology begins primarily with conducting a
literature search on the theories relating to user requirements and medical device development. The
paper outlines these findings through initially describing users and user involvement and relating
them to medical devices. The cross-disciplinary nature of healthcare influenced the investigation into
multiple disciplines including; IT, Ergonomics – particularly participatory research, Psychology and
Design. These disciplines expose various methods and processes, which are useful to user
requirements research. These methods were analysed for their compatibility, and then used to
construct a conceptual framework for user involvement in MDD.
Results: The research insinuates the true significance of user involvement and hence resulted in the
formation of a conceptual framework to aid user involvement in the MDD process. The framework is
produced by the amalgamation of relevant methods examined across the disciplines, in a
complimentary fashion.
Conclusion: The originality of this research lies in its use of a multidisciplinary approach. Previous
research claiming multi-methods has dealt with combining two disciplines or methods at a time i.e.
Computer supported cooperative work (CSCW) with participatory research (Scandurra et al, 2008)
for the needs analysis of healthcare professionals only. Collaboration across disciplines has also been
investigated (Johnson et al, 2005), but this was for the purpose of redesign rather than initial designs.
This framework can help medical device designers to fully access all user requirements through more
extensive collaboration right at the start. It reduces the risk of high costs involved in device rejection,
usually associated with belated recognition of user needs in the design cycle

Look Who's Talking Now: Implications of AV's Explanations on Driver's Trust, AV Preference, Anxiety and Mental Workload
Explanations given by automation are often used to promote automation
adoption. However, it remains unclear whether explanations promote acceptance
of automated vehicles (AVs). In this study, we conducted a within-subject
experiment in a driving simulator with 32 participants, using four different
conditions. The four conditions included: (1) no explanation, (2) explanation
given before or (3) after the AV acted and (4) the option for the driver to
approve or disapprove the AV's action after hearing the explanation. We
examined four AV outcomes: trust, preference for AV, anxiety and mental
workload. Results suggest that explanations provided before an AV acted were
associated with higher trust in and preference for the AV, but there was no
difference in anxiety and workload. These results have important implications
for the adoption of AVs.Comment: 42 pages, 5 figures, 3 Table
Reflections on Mira : interactive evaluation in information retrieval
Evaluation in information retrieval (IR) has focussed largely on noninteractive evaluation of text retrieval systems. This is increasingly at odds with how people use modern IR systems: in highly interactive settings to access linked, multimedia information. Furthermore, this approach ignores potential improvements through better interface design. In 1996 the Commission of the European Union Information Technologies Programme, funded a three year working group, Mira, to discuss and advance research in the area of evaluation frameworks for interactive and multimedia IR applications. Led by Keith van Rijsbergen, Steve Draper and myself from Glasgow University, this working group brought together many of the leading researchers in the evaluation domain from both the IR and human computer interaction (HCI) communities. This paper presents my personal view of the main lines of discussion that took place throughout Mira: importing and adapting evaluation techniques from HCI, evaluating at different levels as appropriate, evaluating against different types of relevance and the new challenges that drive the need for rethinking the old evaluation approaches. The paper concludes that we need to consider more varied forms of evaluation to complement engine evaluation
