Post: 9/11: hidden pedagogy: the positional forces of pedagogy in Victoria, Australia

This qualitative study charts the lived narratives of twelve participants, six teachers and six students from urban and rural Victoria, Australia. The study examines in detail the question ‘How do teachers teach, post 9/11?’. 9/11 has become accepted shorthand for September 11th 2001, in which terrorist attacks took place in the United States of America. The attacks heralded a ‘post- 9/11 world, [in which] threats are defined more by the fault lines within societies than by the territorial boundaries between them’ (National Commission on Terrorist Attacks, 2011, p. 361). The study is embedded in the values that have come to the fore in the wake of the 9/11 attacks and the ideological shifts that have occurred globally. These values and ideologies are reflected via issues of culture and consumption. In education this is particularly visible through pedagogy. The research employs a multimethodological (Esteban-Guitart, 2012) form of inquiry through the use of bricolage (Kincheloe & Berry, 2004) which is comprised at the intersectional points of critical pedagogy (Kincheloe, 2008b), public pedagogy (Sandlin, Schultz, & Burdick, 2010b) and cultural studies (Hall, Hobson, Lowe, & Willis, 1992). This study adopts a critical ontological perspective, and is grounded in qualitative research approaches (Lather & St. Pierre, 2013). The methods of photo elicitation, artefact analysis, video observation and semi-structured interviews are used to critically examine the ways in which teacher and student identities are shaped by the pedagogies of contemporary schooling, and how they form common sense understandings of the world and themselves, charting possibilities between accepted common sense beliefs and 21st century neoliberal capitalism. The research is presented through a prototypical form of literary journalism and intertextuality which examines the interrelationship between teaching and social worlds exposing the hidden influence of enculturation and addressing the question ‘How do teachers teach, post 9/11?’

A method for the visual representation of historic multivariate point data

The visual representation of multivariate spatial and temporal data is important for interpreting and analyzing historical geographic patterns that change over time. The introduction of geospatial technologies in historical scholarship has challenged the suitability of current visual representations due to the need for greater temporal emphasis and the tracking of historical events over time. This research presents a holistic multivariate approach to historical visual representation for point based historical data. The method has been developed through extending the spatial presence in information graphics and through meaningful spatial classification. This paper demonstrates the benefits gained from integrating historical, geographic, temporal, and attribute data through the development of a case study on the history of Melbourne’s cinema venues between 1946 and 1986.

Visual feedback control of a robot in an unknown environment (learning control using neural networks)

In this paper, a visual feedback control approach based on neural networks is presented for a robot with a camera installed on its end-effector to trace an object in an unknown environment. First, the one-to-one mapping relations between the image feature domain of the object to the joint angle domain of the robot are derived. Second, a method is proposed to generate a desired trajectory of the robot by measuring the image feature parameters of the object. Third, a multilayer neural network is used for off-line learning of the mapping relations so as to produce on-line the reference inputs for the robot. Fourth, a learning controller based on a multilayer neural network is designed for realizing the visual feedback control of the robot. Last, the effectiveness of the present approach is verified by tracing a curved line using a 6-degrees-of-freedom robot with a CCD camera installed on its end-effector. The present approach does not necessitate the tedious calibration of the CCD camera and the complicated coordinate transformations.

Experiential learning in practice as research: context, method, knowledge

Creative arts research is often motivated by emotional, personal and subjective concerns; it operates not only on the basis of explicit and exact knowledge, but also on that of tacit and experiential knowledge. Experience operates within in the domain of the aesthetic and knowledge produced through aesthetic experience is always contextual and situated. The continuity of artistic experience with normal processes of living is derived from an impulse to handle materials and to think and feel through their handling. The key term for understanding the relationship between experience, practice and knowledge is 'aesthetic experience', not as it is understood through traditional eighteenth century accounts, but as 'sense activity'.

In this article, I will draw on the work of John Dewey, Michael Polanyi and others to argue that creative arts practice as research is an intensification of everyday experiences from which new knowledge or knowing emerges. The ideas presented here will be illustrated with reference to case studies based on reflections, by the artists themselves, on successful research projects in dance, creative writing and visual art.

Investigating the shared visual context in distributed collaborative work

Distributed collaborators require computermediated communication (CMC) technologies in order to work together. Various systems have been developed for this express purpose with varying degrees of success. A basic method of evaluating the usability of a system is to compare it with face-to-face interaction. To replicate the face-to-face context, it is necessary to investigate how visual information plays a role in supporting collaborators performing tasks.
This research examines the effects of visual information and its role in both face-to-face and video generated visual contexts. The results were generated by asking participants to collaboratively solve visual tasks in either of the two contexts. The results show that both the face-to-face and the video conferencing contexts have similar effects on subjects’ ability to perform tasks. Task outcomes exhibited no significant difference between these two contexts. Awareness and conversational grounding had positive effects on the subject’s task performance and communication. On the other hand, presence had mixed effects on a subject’s task performance and communication behaviors.

Visual guidance during competition performance and run-through training in long jumping

To ensure precise foot placement on the take-off board, long jumpers visually regulate their stride pattern during their run-up. A relationship between how much visual guidance they use and the horizontal distance they jump has not, however, been quantified. Run-up precision is often practiced using run-throughs, which exclude the take-off and, therefore, the high physical stress of the complete long jump. The validity with which this common training method simulates the long jump approach remains, however, to be verified. Four state-standard long jumpers and two heptathletes completed two sessions, each comprising six run-throughs and six competition long jumps. A 50 Hz video camera was manually panned from an elevated platform to film each trial, to enable subsequent gait characteristic evaluations. Linear regression analyses identified that a longer visual regulation phase, measured in time, distance or number of strides, was a key predictor of long jump distance. The number of strides that were visually regulated during the long jump approach was, accordingly, positively correlated with long jump distance (r = 0.67, p = 0.001). The amount of visual regulation used during run-throughs was, however, less than half (p = 0.001) of that observed during long jump approaches. Our results should compel long jump coaches to supplement run-through training with additional visual guidance exercises, to encourage their athletes to visually regulate more of their long jump approach.

The reliability of two visual motor integration tests used with health adults

Occupational therapists often assess the visual motor integration (VMI) skills of children, adults, and the elderly, which are parts of the Body Functions and Structures of the International Classification of Functioning, Disability and Health. Objective. As it is imperative that therapists use tests and measures with strong psychometric properties, this study aims to examine the reliability of two VMI tests used with adults. Method. Sixty-one healthy adults, 18 males and 43 females, with an average age of 31.82 years, completed the Developmental Test of Visual Motor Integration (DTVMI) and the Full Range Test of Visual Motor Integration (FRTVMI). The Cronbach's alpha coefficient was used to examine the tests’ internal consistency, while the Spearman's rho correlation was used to evaluate the test–retest reliability, intrarater reliability, and interrater reliability of the two VMI tests. Results. The Cronbach's alpha coefficient for the DTVMI and FRTVMI was 0.66 and 0.80, respectively. The test–retest reliability coefficient was 0.77 (p < .001) for the DTVMI and 0.61 (p < .001) for the FRTVMI. The interrater reliability correlation was significant for both DTVMI at 0.79 (p < .001) and FRTVMI at 0.80 (p < .001). The DTVMI intrarater reliability correlation result was 0.95 (p < .001) and the FRTVMI at 0.87 (p < .001). Conclusion. Overall, the DTVMI and the FRTVMI exhibited moderate to high levels of reliability when used with a sample of healthy adults. Both VMI tests appear to exhibit reasonable levels of reliability and are recommended for use with adults and the elderly.

Evaluation of thermal and visual comfort in offices considering realistic input data and user behaviour in building simulation

Thermal and visual comfort play a very important role regarding the satisfaction of occupants with their working environments. The most effective method to achieve thermal comfort in offices is to reduce cooling loads in order to avoid additional energy-consuming devices for cooling. Building simulation software can be a helpful tool for optimisation, and typically standard values for the influencing parameters are used in order to ensure compliance to norms and regulations.

In practice many of those parameters turn out to be different compared to the simulation assumptions and the reasons may be the chosen room or building related properties as well as the user behaviour influenced by the task and the corporate culture of the company.

This paper investigates exemplary for the climate of Hamburg, Germany and a naturally ventilated typical office room, the optimisation potential of the building- and user-related parameters for thermal comfort, daylighting and view when using realistic input data for building simulation. The study has been conducted with the EnergyPlus based simulation software “Primero-Komfort” [1].

What's in a measure? A multi-method study of child sexual offenders' beliefs

The hypothesis that child sexual offenders (CSOs) hold distorted, offence-supportive beliefs is usually investigated using interview and questionnaire techniques. However, in light of various problems associated with the use of these techniques, researchers are increasingly turning to cognitive-experimental approaches. To date, no study has examined potential differences in the nature of the beliefs that are revealed using interview, questionnaire, and experimental methods. In this study, data is gathered using these three methods and the results triangulated. CSOs are interviewed and the content categorised into five belief types. CSOs and offender controls then complete a questionnaire measure of offence-supportive beliefs and an experimental task (Rapid Serial Visual Presentation-Modified, or RSVP-M), which uses sentence reading times to explore content held in cognitive structures. As hypothesised, CSOs showed evidence of holding distorted beliefs according to the interview and questionnaire measures. Against predictions, however, CSOs did not show evidence of holding distorted belief structures on the RSVP-M task. In fact, the three methods showed no agreement regarding the belief types each CSO was deemed to hold. These results raise important questions about the phenomena and potential artefacts measured by each method.

Convergent validity of two visual motor integration tests

Background: Occupational therapists often assess visual motor integration (VMI) skills. It is, therefore, imperative that therapists use VMI tests with robust measurement properties.

Objective: This study examined the convergent validity of two VMI tests used to assess children, adolescents and adults.

Method: Three groups of healthy participants (n = 153) completed the Beery-Buktenica Developmental Test of Visual-Motor Integration (DTVMI) and the Full Range Test of Visual Motor Integration (FRTVMI). Seventy-three children aged 5-10 years (37 males and 36 females; mean age 7.5 years, SD = 2.20), 19 adolescents aged 11-17 years (8 males and 11 females; 13.1 years, SD = 2.16), and 61 adults (18 males and 43 females; mean age 31.82 years, SD = 11.20) completed the DTVMI and the FRTVMI. Spearman rho correlation coefficients were used to investigate whether each pair of the VMI test scores for each of the three participant age groups were associated.

Results: The Spearman rho correlation coefficients between all three versions of the DTVMI and FRTVMI were statistically significant. For the child group, the correlation coefficient was rho = 0.70 (p<0.000), while the correlation between the VMI scores obtained by the adolescent group on the two tests was rho = 0.77 (p<0.000). For the adult participant group, the correlation coefficient between the DTVMI and the FRTVMI was rho = 0.70 (p<0.000).

Conclusion: The VMI scores obtained by the three participant age groups on the DTVMI and the FRTVMI were all significantly correlated with each other. Overall, the DTVMI and the FRTVMI exhibited large levels of convergent validity with each other, indicating that the two tests appear to measure similar visual-motor integration constructs.

User-centered design and evaluation of an interactive visual-haptic-auditory interface : a user study on assembly

Utilizing user-centred system design and evaluation method has become an increasingly important tool to foster better usability in the field of virtual environments (VEs). In recent years, although it is still the norm that designers and developers are concerning the technological advancement and striving for designing impressive multimodal multisensory interfaces, more and more awareness are aroused among the development team that in order to produce usable and useful interfaces, it is essential to have users in mind during design and validate a new design from users' perspective. In this paper, we describe a user study carried out to validate a newly developed haptically enabled virtual training system. By taking consideration of the complexity of individual differences on human performance, adoption and acceptance of haptic and audio-visual I/O devices, we address how well users learn, perform, adapt to and perceive object assembly training. We also explore user experience and interaction with the system, and discuss how multisensory feedback affects user performance, perception and acceptance. At last, we discuss how to better design VEs that enhance users perception, their interaction and motor activity.
