Blake philosophy teaching


Blake, Nigel (2000)
Tutors and Students without Faces or Places
Journal of Philosophy of Education, 34,1, 183-196

Reflect on distance education
P183 ‘Centrally, tuition is conducted here in personal interaction through the written word’. P 183 ‘However, it is constantly compared and contrasted negatively with conventional education in at least one respect: that it is not ‘face-to-face’ it is the alternative for students who need to study at a distance. There is a notion that  interaction by means of the written word diminishes the quality of communication between tutors and students. ‘ the belief that body language , as an aspect of communication, is an unqualified good’ KRO what would constitute an adequate defence of these claims?

P 184 ‘The idea that there is something special and important about the physical co-presence of teachers and students may be ill-articulated but it obviously has plausible appeal’ Lets take the scenario of the way that the distance learner will study.  The live teacher is replaced by a teaching text crafted by a live teacher. P184 ‘ Instead of the text actually teaching, the student has to actively study the text’….p185 ‘ So if we force the question what goes on, teaching or study, on such occasions, the question has really no point of interest. The answer is rather that a conventional link between teaching and physical presence is less fundamental that we often think and has been broken here’

Evaluate face-to-face
lets dissect a face-to-face interaction – what kind of speech acts are involved, greetings & the exchange of pleasantries, compliments, jokes, advice, warnings, rebukes, insults, evasions. Although they all have a cognitive element  (they involve information exchange) constatives, there is also a large element of  the performative, p186 ‘ whose character as social actions is at least as important as their character of communicating information’ ( KRO and that has been the challenging part of constructing the narrative) ‘ As speech acts, as events at some particular time and place, performatives are highly sensitive to social and material context.’ In contrast constatives are not so reliant on context. Constatives tend to be right or wrong, whereas perfomatives are either successful or unsuccessful. Perfomatives can misfire, the social background has to be properly understood by both the speaker and the hearer p 186 ‘Plausibly, it is the nature of the social relationship between the speakers and how it is reinforced or transformed which is the important issue in these speech interactions’ performatives are easily aligned with familiar kinds of intonation, body language and facial expression. In these cases of mundane face-to-face interaction, there seems a characteristic intertwining between the physical and the verbal……..there is something patently appropriate about physical interaction in these banal contexts. Those with whom we cement relationships, are embodied people, and their personal characteristics as embodied are often relevant to the nature of the relationship we have with them. Moreover, the inherent actual or potential embodiedness of relationships – the inherent address of relationships to the Other as embodied – is betrayed by the fact that ‘body language’ and facial expression are not in fact simply items of a kind of shared, intuitive physical  ‘ vocabulary’ . They also reveal aspects of ourselves to other quite unintentionally and often without us realising it, thus cementing or impeding relationships all the more effectively. So in this unconscious way too, bodies can and do intervene in the construction of relationships’ and it is context sensitive.  (KRO therefore important to retain the context for the narratives)

What is appropriate for academic interactions, particularly in HE?
Focus – the substance and complexities of the discipline, not on our selves, our own interests or even on our personal reactions to the topic.
Values – disinterestedness
Vices – bias, partiality, vested interest, prejudice
Role ‘Academic objectivity requires us to sift very carefully questions of true and false, right and wrong, valid or invalid, good and bad, insightful or obtuse from those of personal taste or distaste, political or religious commitment, fear or loathing, enthusiasm or delight’
Skill/ Competence p 188 ‘the personal, the subjective and the individual have to be somehow bracketed off and kept in their place, on both sides of the teaching interaction….. one of the tasks of  a teacher may often be to alert the student to her own lapses of objectivity, to the moments where her own personal values, emotions, and limitations may be clouding or distorting her judgement’  Therefore in face-to-face academic practice there is a presumption about the ‘non-verbal as being inappropriate’, ‘that academic life has its own decorum, functional for the pursuit of its higher aims. The purpose of this decorum is precisely to bracket off, to tame or even sometimes to expunge the influence of non-academic personal relations, personal interests and commitments’ that the personal ‘is an impediment to distinterestedness’ ie the non-verbal  (that extends the communicative repetiore) may be irrelevant or invidious even to academic teaching.

Academic interactions online
’In the previous section we explored the idea that cognitive use of language comes first in academia. ‘p 193 ‘ If online tuition is to be genuine teaching, then insightful interpretation of the student’s written word is at a premium. The question is not ‘ “What do these words mean?” but “What does this student mean [by these words]” And in addressing that particular problem, any indications the tutor can garner from the student’s text may seem relevant and appropriate to the task. Moreover, we cannot assume any a priori limits as to what aspects of a student’s life and experience will influence or inform her own attempts to make sense of academic material and ideas’

Top IT issues

What's the trend of the year in educational technology? Most people would immediately shout out MOOCs (as I predicted way back in January, 2012 - the year of the MOOC) but according to anEducause survey, Top-10 IT issues 2012,  the most important concerns are not whether to join the MOOC movement but the fundamental issue of how to integrate IT into all of the university's activities and develop more mature strategies for the use of technology.

The survey asked a panel of higher education IT experts what the biggest single IT-realted issue facing their institution had been in 2012. Here's their top ten:
  1. Updating IT professionals' skills and roles to accommodate new technologies and changing IT delivery models
  2. Supporting IT consumerization and bring-your-own device programs
  3. Developing a cloud strategy
  4. Improving the institution's operational efficiency through IT
  5. Integrating IT into institutional decision-making
  6. Using analytics to support the important institutional outcomes
  7. Funding IT initiatives
  8. Transforming the institution's business with IT
  9. Supporting research with high-performance computing, large data, and analytics
  10. Establishing and implementing IT governance throughout the institution

The common thread here is the need to integrate technology use into all areas of the university from the management down and to ensure that staff have the right competence to deal with this change. IT is no longer simply a technology issue and is no longer limited to the IT department; it supports all processes and affects every member of staff. Educational technology is moving from a marginal pioneer movement of enthusiasts to mainstream and default. Institutional strategies are now needed where before there were simply uncoordinated grassroots initiatives. The tools and software that were once provided in-house are now freely available in the cloud and at the same time the carefully controlled infrastructure of university owned computer labs is being replaced by students using their own devices and expecting access anywhere any time.

The challenges facing the role of IT in higher education are finding strategies of benefitting from the diversity and freedom of cloud-based solutions and personal devices while maintaining some level of control and security. The survey highlight above all else the rapidly changing role of the university IT department.

"This year's list transcends the IT org chart with two predominant themes: the IT organization's obligation to the institution; and the IT organization's relationship to technology outside the institution. The former views the IT organization as an enabler and partner in helping colleges and universities adapt to and even capitalize on changing realities and needs via automation (Issue #4), analytics (Issue #6), business transformation (Issue #8), and research computing (Issue #9). It also recognizes that the IT organization's relationship with institutional leaders must be effective for it to truly support institutional priorities, by integrating information technology into institutional decision-making (Issue #5), funding information technology strategically (Issue #7), and establishing and implementing IT governance throughout the institution (Issue #10)."

Learning to control brain activity improves visual sensitivity

5 December 2012
Training eople to control their own brain activity can enhance their visual sensitivity, according to a new study. This non-invasive ‘neurofeedback’ approach could one day be used to improve brain function in patients with abnormal patterns of activity, for example after a stroke.
Researchers at the Wellcome Trust Centre for Neuroimaging at UCL used non-invasive, real-time brain imaging that enabled participants to watch their own brain activity on a screen, a technique known as neurofeedback. During the training phase, they were asked to try to increase activity in the area of the brain that processes visual information, the visual cortex, by imagining images and observing how their brains responded.
After the training phase, the participants' visual perception was tested using a new task that required them to detect very subtle changes in the contrast of an image. When they were asked to repeat this task while clamping brain activity in the visual cortex at high levels, those who had successfully learned to control their brain activity could improve their ability to detect even very small changes in contrast.
This improved performance was only observed when participants were exercising control over their brain activity.
Lead author Dr Frank Scharnowski, who is now based at the University of Geneva, explains: "We've shown that we can train people to manipulate their own brain activity and improve their visual sensitivity, without surgery and without drugs."
In the past, researchers have used recordings of electrical activity in the brain to train people on various tasks, including cutting their reaction times, altering their emotional responses and even improving their musical performance. In this study, the researchers used functional magnetic resonance imaging (fMRI) to provide the volunteers with real-time feedback on brain activity. The advantage of this technique is that you can see exactly where in the brain the training is having an effect, so you can target the training to particular brain areas that are responsible for specific tasks.
"The next step is to test this approach in the clinic to see whether we can offer any benefit to patients, for example to stroke patients who may have problems with perception, even though there is no damage to their vision," adds Dr Scharnowski.
The study, funded by the Wellcome Trust, the Swiss National Science Foundation and the European Union, is published online today in the 'Journal of Neuroscience'.
