Short sprint or an endurance test: the perceived impact of the National Award for Special Educational Needs Coordination     

Julian Brown  Mary Doveston 《Teacher Development》2014,18(4):495-510

This paper evaluates the perceived impact of the National Award (NA) for Special Educational Needs (SEN) Coordination in English mainstream schools. The Award was introduced in 2009 and has been mandatory for all new Special Educational Needs Coordinators (SENCos) since its inception. The framework used for the evaluation is based on the learning outcomes of the NA, which were formulated by the Training and Development Agency and focus on areas related to the pedagogical, managerial and leadership aspects of the SENCo role. Findings suggest that the NA has impacted most significantly on participants’ pedagogy and strategies for removing barriers to learning. Participants’ preparedness for training at post-graduate level is also investigated and consideration is given towards further training and study beyond the completion of the NA. Additionally, the paper investigates areas that are perceived as challenges (e.g. lack of time and leadership status) to the successful implementation of their coordination role and any impact the NA has had in this respect.  相似文献   

Magnetophoretic-based microfluidic device for DNA isolation     

C. Hale  J. Darabi 《Biomicrofluidics》2014,8(4)

This paper presents a continuous flow microfluidic device for the separation of DNA from blood using magnetophoresis for biological applications and analysis. This microfluidic bio-separation device has several benefits, including decreased sample handling, smaller sample and reagent volumes, faster isolation time, and decreased cost to perform DNA isolation. One of the key features of this device is the use of short-range magnetic field gradients, generated by a micro-patterned nickel array on the bottom surface of the separation channel. In addition, the device utilizes an array of oppositely oriented, external permanent magnets to produce strong long-range field gradients at the interfaces between magnets, further increasing the effectiveness of the device. A comprehensive simulation is performed using COMSOL Multiphysics to study the effect of various parameters on the magnetic flux within the separation channel. Additionally, a microfluidic device is designed, fabricated, and tested to isolate DNA from blood. The results show that the device has the capability of separating DNA from a blood sample with a purity of 1.8 or higher, a yield of up to 33 μg of polymerase chain reaction ready DNA per milliliter of blood, and a volumetric throughput of up to 50 ml/h.  相似文献   

The application of transformational leadership theory to parenting: questionnaire development and implications for adolescent self-regulatory efficacy and life satisfaction     

Morton KL  Barling J  Rhodes RE  Mâsse LC  Zumbo BD  Beauchamp MR 《运动与训练心理学杂志》2011,33(5):688-709

We draw upon transformational leadership theory to develop an instrument to measure transformational parenting for use with adolescents. First, potential items were generated that were developmentally appropriate and evidence for content validity was provided through the use of focus groups with parents and adolescents. We subsequently provide evidence for several aspects of construct validity of measures derived from the Transformational Parenting Questionnaire (TPQ). Data were collected from 857 adolescents (M(age) = 14.70 years), who rated the behaviors of their mothers and fathers. The results provided support for a second-order measurement model of transformational parenting. In addition, positive relationships between mothers' and fathers' transformational parenting behaviors, adolescents' self-regulatory efficacy for physical activity and healthy eating, and life satisfaction were found. The results of this research support the application of transformational leadership theory to parenting behaviors, as well as the construct validity of measures derived from the TPQ.  相似文献

Identification with early primary school mathematics: a home–school activity theory conceptualisation and methodology     

Laura Black  Julian Williams  Sophina Choudry  Kelly Pickard-Smith  Bethany Ryan 《Cambridge Journal of Education》2019,49(3):349-368

This paper offers a new methodology for researching children’s identifications in the early primary phase that makes visible the ‘seeds’ of academic dis-/identities, which typically flower later in adolescence. It focuses on the ‘case’ of mathematical identifications (MI) to exemplify how children come to dis/identify from the academic curriculum more broadly. MI is defined as any act where cultural representations of being mathematical are reflected back on to the child by others or the self, as they engage in mathematical activity. Data are presented concerning Bilal and Nico to show identifications in a hybrid home–school mathematics activity that contradict or ‘align’ with MI elicited in school-mathematical activity. It is argued that contradictions between these MIs indicate ‘potential’ development towards disengagement (the case of Nico). This contrasts with home–school alignment involving Bilal’s ‘schoolified’ home activities, which (re)validate school-mathematical activity. It is further argued that this conceptual innovation offers potential for investigating identity in early childhood.  相似文献   

古希腊神示所之谜

当科学与宗教在古希腊神示所狭路相逢,它们的关系比学者们原先预想的要融洽得多. 举世闻名的阿波罗神殿,座落在希腊德尔斐风景如画的山区,是古希腊最重要的宗教场所,因为法力无边的德尔斐神示所就在这座神殿里.在重男轻女的古希腊异乎寻常的是,Pythia必须是女性,而且职位的继承与家族的显赫无关.  相似文献   

In Pursuit of Knowledge: Preschoolers Expect Agents to Weigh Information Gain and Information Cost When Deciding Whether to Explore     

Rosie Aboody  Caiqin Zhou  Julian Jara-Ettinger 《Child development》2021,92(5):1919-1931

When deciding whether to explore, agents must consider both their need for information and its cost. Do children recognize that exploration reflects a trade-off between action costs and expected information gain, inferring epistemic states accordingly? In two experiments, 4- and 5-year-olds (N = 144; of diverse race and ethnicity) judge that an agent who refuses to obtain low-cost information must have already known it, and an agent who incurs a greater cost to gain information must have a greater epistemic desire. Two control studies suggest that these findings cannot be explained by low-level associations between competence and knowledge. Our results suggest that preschoolers’ theory of mind includes expectations about how costs interact with epistemic desires and states to produce exploratory action.  相似文献   

Reinstatement after counterconditioning     

Douglas C. Brooks  Beth Hale  James B. Nelson  Mark E. Bouton 《Learning & behavior》1995,23(4):383-390

Reinstatement after counterconditioning was examined in three experiments with rats. The rats received CS-shock pairings in Phase 1 and then CS-food pairings in Phase 2. When unsignaled shock was presented after appetitive conditioning, fear performance to the CS replaced food performance. This reinstatement effect depended on initial pairings of the CS and shock in Phase 1. It also depended on shock exposure occurring in the test context. The results parallel previous data obtained after extinction. Counterconditioning and extinction yield several parallel effects (spontaneous recovery, renewal, and now reinstatement) which suggest that Phase 2 does not destroy the learning acquired in Phase 1.  相似文献
