Learning from demonstrations: the role of visual search during observational learning from video and point-light models

In this study, we examined the visual search strategies used during observation of video and point-light display models. We also assessed the relative effectiveness of video and point-light models in facilitating the learning of task outcomes and movement patterns. Twenty-one female novice soccer players were divided equally into video, point-light display and no-model (control) groups. Participants chipped a soccer ball onto a target area from which radial and variable error scores were taken. Kinematic data were also recorded using an opto-electrical system. Both a pre- and post-test were performed, interspersed with three periods of acquisition and observation of the model. A retention test was completed 2 days after the post-test. There was a significant main effect for test period for outcome accuracy and variability, but observation of a model did not facilitate outcome-based learning. Participants observing the models acquired a global movement pattern that was closer to that of the model than the controls, although they did not acquire the local relations in the movement pattern, evidenced by joint range of motion and angle-angle plots. There were no significant differences in learning between the point-light display and video groups. The point-light display model group used a more selective visual search pattern than the video model group, while both groups became more selective with successive trials and observation periods. The results are discussed in the context of Newell's hierarchy of coordination and control and Scully and Newell's visual perception perspective.     

Quantum lithography: A?non-computing application of quantum information

Quantum information theory holds the promise of revolutionizing technologies other than computing and communications. In this article we show how quantum entanglement can be harnessed to beat the Rayleigh diffraction limit of conventional optical lithography, and to permit nano-devices to be fabricated at a scale arbitrarily shorter than the wavelength used. Given the relative ease of performing optical lithography compared with other schemes, and the relative costs associated in migrating the lithography industry to each new fabrication technology, exploiting quantum entanglement to extend the useful life of optical lithography could be economically attractive.     

Lessons from a master: Montaigne’s pedagogy of conversation

There remains much to be learned from searching exploration of the great authors who have meditated on education. Montaigne is one such thinker and this essay endeavors to draw together the strands of his pedagogy and to demonstrate how they gain purchase in the business of teaching and learning. The article also proposes to supplement his vision with practical examples from fiction and autobiography. Perhaps the most striking theme is the need to be able to decentre from the comfort zone of acquired beliefs and convictions and the crucial role played by conversation in cultivating the intellectual and moral openness in order to do so. At the heart of Montaigne’s writing on education is what can be called a pedagogy of conversation.     

Carving Metacognition at Its Joints: Protracted Development of Component Processes

Two experiments investigated the development of metacognitive monitoring and control, and conditions under which children engage these processes. In Experiment 1, 5‐year‐olds (N = 30) and 7‐year‐olds (N = 30), unlike adults (N = 30), showed little evidence of either monitoring or control. In Experiment 2, 5‐year‐olds (N = 90) were given performance feedback (aimed at improving monitoring), instruction to follow a particular strategy (aimed at improving control), or both. Across conditions, feedback improved children's monitoring, and instruction improved both monitoring and control. Thus, children's poor metacognitive performance likely reflects a difficulty engaging the component processes spontaneously rather than a lack of metacognitive ability. These findings also suggest that the component processes are distinct, with both undergoing protracted development.

A New Method of Revealing Armourers’ Marks

In this research, we performed radiographic experiments exploiting polychromatic phase-contrast imaging, a method for contrast enhancement in transmitted neutron beams by measuring a sample made with a homogeneous material but exhibiting a different microstructure induced by mechanical actions. We were able to reveal the armourers’ marks now obscured by polishing that are present in these examples of medieval armour.     

Personal factors and personal information activities behaviors of faculty in selected universities in Ghana

This study examined how demographic characteristics of faculty influence their personal information activities behaviors, namely information creation, information organization, and information storage. Data was collected from a sample of 235 faculty in six universities in Ghana using a questionnaire. Age, gender, rank and university of affiliation predicted personal information activities behaviors in different directions and with different magnitudes. Gender made a difference in information organization and information storage while age made a difference in respect of information creation and information organization only. Faculty ages 4049 years created information the most, followed by those above 50 years. Males stored information more than females. Rank made a difference in information creation, organization and storage, but university of affiliation made a difference in information creation and information storage, and not information organization. It is common among information system designers and managers to implement information management systems without considering the differential influence of personal variables on human information behaviors. This omission denies information users adequate access and maximum use of the information in their information space. Institutional leaders and PIM systems designers should consider demographic and other personal factors of faculty in information literacy programs. Profiling of users' personal characteristics when designing personal information management systems will enhance maximum access and utilisation of personal information.     

Longitudinal literacy professional development in an urban elementary charter school

The authors describe a school-university professional development partnership in a high-needs urban elementary charter school. University and school partners collaborated to build instructional capacity to develop teachers’ understanding and implementation of effective literacy instruction. Design-based research revealed increased understanding and implementation of effective literacy practices among school leaders and teachers. Findings revealed the importance of administrative stability; coaching support; and a focused, school-wide instructional vision.     

Examining teachers’ perceptions of K‐11 students’ 21st century skills and student performance

This study examined the relationship of teachers’ ratings of students’ 21st century skills (i.e., persistence, curiosity, externalizing and internalizing affect, and cognition) via the Human Behavior Rating Scale: Brief (HBRS: Brief; Eaves & Woods‐Groves, 2011) with student performance. Midwestern K‐11 teachers (n = 96) rated students (n = 1,689) via the HBRS: Brief and the Strengths and Difficulties Questionnaire (SDQ; Goodman, 1997). Students’ academic (i.e., standardized tests) and behavioral (i.e., office discipline referrals [ODRs] and absences) performance was compared with HBRS: Brief ratings. Hierarchical linear modeling revealed that teachers’ ratings of students’ 21st century skills were related to the following: (a) Persistence with SDQ conduct problems, academic performance, and absences; (b) curiosity with SDQ emotional symptoms; (c) externalizing affect with SDQ conduct problems, academic performance, and ODRs; (d) internalizing affect with SDQ emotional symptoms and academic performance, and (e) cognition with academics.
