Conditions for young infants' perception of object trajectories

When an object moves behind an occluder and re-emerges, 4-month-old infants perceive trajectory continuity only when the occluder is narrow, raising the question of whether time or distance out of sight is the important constraining variable. One hundred and forty 4-month-olds were tested in five experiments aimed to disambiguate time and distance out of sight. Manipulating the object's visible speed had no effect on infants' responses, but reducing occlusion time by increasing object speed while occluded induced perception of trajectory continuity. In contrast, slowing the ball while it was behind a narrow or intermediate screen did not modify performance. It is concluded that 4-month-olds perceive trajectory continuity when time or distance out of sight is short.     

Young,free and single? Theorising partner relationships during the first year of university

Recent research into young people’s private social worlds has highlighted the significance of family and friend relationships for students’ experiences of the transition to university. Drawing on data generated through a qualitative longitudinal study with 24 young women undergraduate students, this paper provides an original contribution to this growing body of literature by bringing committed partner relationships into view. The following discussion uses the notion of the ‘moral tale’ in order to reveal the ways in which singleness and commitment to a partner were experienced and articulated by young women undergraduate students at this important juncture. This paper raises important questions about how young women are able to take on ‘traditional’ and ‘authentic’ student identities whilst also remaining connected to important sources of love and support at this time of heightened change     

Internet‐based information‐seeking behaviour amongst doctors and nurses: a short review of the literature

Background: Reviews of how doctors and nurses search for online information are relatively rare, particularly where research examines how they decide whether to use Internet‐based resources. Original research into their online searching behaviour is also rare, particularly in real world clinical settings. as is original research into their online searching behaviour. This review collates some of the existing evidence, from 1995 to 2009. Objectives: To establish whether there are any significant differences in the ways and reasons why doctors and nurses seek out online information; to establish how nurses and doctors locate information online; to establish whether any conclusions can be drawn from the existing evidence that might assist health and medical libraries in supporting users. Methods: An initial scoping literature search was carried out on PubMed and CINAHL to identify existing reviews of the subject area and relevant original research between 1995 and 2009. Following refinement, further searches were carried out on Embase (Ovid), LISA and LISTA. Following the initial scoping search, two journals were identified as particularly relevant for further table of contents searching. Articles were exclused where the main focus was on patients searching for information or where the focus was the evaluation of online‐based educational software or tutorials. Articles were included if they were review or meta‐analysis articles, where they reported original research, and where the primary focus of the online search was for participants’ ongoing Continuing Professional Development (CPD). The relevant articles are outlined, with details of numbers of participants, response rates, and the user groups. Results: There appear to be no significant differences between the reasons why doctors and nurses seek online Internet‐based evidence, or the ways in which they locate that evidence. Reasons for searching for information online are broadly the same: primarily patient care and CPD (Continuing Professional Development). The perceived barriers to accessing online information are the same in both groups. There is a lack of awareness of the library as a potential online information enabler. Conclusions: Libraries need to examine their policy and practice to ensure that they facilitate access to online evidence‐based information, particularly where users are geographically remote or based in the community rather than in a hospital setting. Librarians also need to take into account the fact that medical professionals on duty may not be able to take advantage of the academic model of online information research. Further research is recommended into the difference between the idealised academic model of searching and real world practicalities; and how other user groups search, for example patients.     

The Other Side of the Gender Gap

In 1990s Britain girls consistently outperform boys in examinations at 16 + . This achievement, however, has taken place in a context where many of the concerns voiced by writers in the 1970s and 1980s have not been resolved. It is argued that there is another side to the so-called 'gender gap': drawing on data from 20 schools in eastern England, it is suggested that girls still feel alienated from traditionally 'male' subjects, that career aspirations are still highly gendered, that boys still dominate the classroom environment, that boys' laddish behaviour can have a negative effect on girls' learning, and that some teachers have lower expectations of girls and find boys more stimulating to teach. In short, the gender debate has been captured by those concerned predominantly with male underachievement, leaving girls to make the best they can in what often continues to be a male-dominated environment.     

Coincidence timing of a tennis stroke: effects of age, skill level, gender, stimulus velocity, and attention demand

Participants (N = 162, ages 10-15 years) performed a tennis stroke in a coincidence-timing task. Major results were: (a) performance improved mainly between the ages of 10-13 years; (b) skill differences were reflected by variable error (VE); (c) boys were lower than girls for VE and absolute error; (d) high stimulus velocity was related to low VE and late responding. Results concerning response organization favored explanations based on ecological perspectives rather than information processingperspectives. However, it is premature to disregard the potential role of programming. The view is supported that a continuous process of coupling perceptual and motor responses coordinates control of response timing. These cognitive processes appear to be: (a) refined with practice; (b) sensitive to differences in age, skill, and gender; and (c) adaptable to changes in environmental demands.     

Preservice teachers’ expressed awarenesses: emerging threads of retro-spection of learning and pro-spection of teaching

In this paper, we report an enquiry into elementary preservice teachers’ learning, as they engage in doing mathematics for themselves. As a group of researchers working in elementary Initial Teacher Education in English universities, we co-planned and taught sessions on growing pattern generalisation. Following the sessions, interviews of fifteen preservice teachers at two universities focused on their expressed awareness of their approach to the mathematical activity. Preservice teachers’ prospective planning and post-teaching evaluations of similar activities in their classrooms were also examined. We draw on aspects of enactivism and the notion of reflective “spection” in the context of teacher learning, tracing threads between preservice teachers’ retro-spection of learning and pro-spection of teaching. Our analysis indicates that increasing sensitivity to their own embodied processes of generalisation offers opportunities for novice teachers to respond deliberately, rather than to react impulsively, to different pedagogical possibilities. The paper contributes a new dimension to the discussion about the focus of novice elementary school teachers’ retrospective reflection by examining how deliberate retrospective analysis of doing mathematics, and not only of teaching actions, can develop awarenesses that underlie the growth of expertise in mathematics teaching. We argue that engaging preservice teachers in mathematics to support deliberate retrospective analysis of their mathematics learning and prospective consideration of the implications for teaching can enable more critical pedagogical choices.

     

Pedagogical possibilities for unruly bodies

Project Re?Vision uses disability arts to disrupt stereotypical understandings of disability and difference that create barriers to healthcare. In this paper, we examine how digital stories produced through Re?Vision disrupt biopedagogies by working as body-becoming pedagogies to create non-didactic possibilities for living in/with difference. We engage in meaning making about eight stories made by women and trans people living with disabilities and differences, with our interpretations guided by the following considerations: what these stories ‘teach’ about new ways of living with disability; how these stories resist neoliberalism through their production of new possibilities for living; how digital stories wrestle with representing disability in a culture in which disabled bodies are on display or hidden away; how vulnerability and receptivity become ‘conditions of possibility’ for the embodiments represented in digital stories; and how curatorial practice allows disability-identified artists to explore possibilities of ‘looking back’ at ableist gazes.     

Using causal models to bridge the divide between big data and educational theory

An extraordinary amount of data is becoming available in educational settings, collected from a wide range of Educational Technology tools and services. This creates opportunities for using methods from Artificial Intelligence and Learning Analytics (LA) to improve learning and the environments in which it occurs. And yet, analytics results produced using these methods often fail to link to theoretical concepts from the learning sciences, making them difficult for educators to trust, interpret and act upon. At the same time, many of our educational theories are difficult to formalise into testable models that link to educational data. New methodologies are required to formalise the bridge between big data and educational theory. This paper demonstrates how causal modelling can help to close this gap. It introduces the apparatus of causal modelling, and shows how it can be applied to well-known problems in LA to yield new insights. We conclude with a consideration of what causal modelling adds to the theory-versus-data debate in education, and extend an invitation to other investigators to join this exciting programme of research.

Practitioner notes

What is already known about this topic

• ‘Correlation does not equal causation’ is a familiar claim in many fields of research but increasingly we see the need for a causal understanding of our educational systems.
• Big data bring many opportunities for analysis in education, but also a risk that results will fail to replicate in new contexts.
• Causal inference is a well-developed approach for extracting causal relationships from data, but is yet to become widely used in the learning sciences.

What this paper adds

• An overview of causal modelling to support educational data scientists interested in adopting this promising approach.
• A demonstration of how constructing causal models forces us to more explicitly specify the claims of educational theories.
• An understanding of how we can link educational datasets to theoretical constructs represented as causal models so formulating empirical tests of the educational theories that they represent.

Implications for practice and/or policy

• Causal models can help us to explicitly specify educational theories in a testable format.
• It is sometimes possible to make causal inferences from educational data if we understand our system well enough to construct a sufficiently explicit theoretical model.
• Learning Analysts should work to specify more causal models and test their predictions, as this would advance our theoretical understanding of many educational systems.
