Newborn irritability moderates the association between infant attachment security and toddler exploration and sociability     

Stupica B  Sherman LJ  Cassidy J 《Child development》2011,82(5):1381-1389

This longitudinal investigation of 84 infants examined whether the effect of 12-month attachment on 18- and 24-month exploration and sociability with unfamiliar adults varied as a function of newborn irritability. As expected, results revealed an interaction between attachment (secure vs. insecure) and irritability (highly irritable vs. moderately irritable) in predicting both exploration and sociability with unfamiliar adults. For exploration, results supported a dual-risk model; that is, toddlers who had been both highly irritable and insecurely attached were less exploratory than other toddlers. For sociability, results supported the differential-susceptibility hypothesis; that is, highly irritable infants, compared to moderately irritable infants, were both less sociable as toddlers when they had been insecurely attached and more sociable when they had been securely attached.  相似文献   

A longitudinal examination of African American adolescents' attributions about achievement outcomes     

Swinton AD  Kurtz-Costes B  Rowley SJ  Okeke-Adeyanju N 《Child development》2011,82(5):1486-1500

Developmental, gender, and academic domain differences in causal attributions and the influence of attributions on classroom engagement were explored longitudinally in 115 African American adolescents. In Grades 8 and 11, adolescents reported attributions for success and failure in math, English and writing, and science. In Grade 11, English and mathematics teachers rated students' classroom engagement. Boys were more likely than girls to attribute math successes to high ability and to attribute English failures to low ability. Both genders' ability attributions for math became more negative from eighth to eleventh grades. Grade 8 attributions of math failure to lack of ability were negatively related to Grade 11 math classroom engagement. Results illustrate the gendered nature of motivational beliefs among Black youth.  相似文献   

Response‐to‐intervention in high‐risk preschools: Critical issues for implementation     

Carrie R. Ball  Beth A. Trammell 《Psychology in the schools》2011,48(5):502-512

This article summarizes the current knowledge of response‐to‐intervention (RTI) models in preschool settings, with an emphasis on evaluating the strengths and weaknesses of our current research base. Particular attention is given to the unique challenges of high‐risk preschool settings. Presently, sufficient empirical support exists to begin establishing tiered intervention systems and building teacher capacity. Lacking, however, are valid and reliable assessment tools and insufficiently trained personnel to support a data‐based decision‐model within high‐risk preschools. We conclude that organizational development should focus on building teacher capacity, establishing high‐quality classroom instruction, and planning for sustainable programs, with adoption of a full RTI service delivery model serving as a long‐range aspirational goal. © 2011 Wiley Periodicals, Inc.  相似文献   

Evaluating the reflexive practices in a learning experience     

Andreina Bruno  Laura Galuppo  Silvia Gilardi 《European Journal of Psychology of Education - EJPE》2011,26(4):527-543

Reflexivity is a primary requirement for professional work. Our aim was to describe a methodology suitable for detecting the development of reflexive practice through the analysis of 59 Master’s degree students’ journals. We explore the use and changes of reflexive practice in relation to the settings and activities of the course using analysis of the mental language: We analyse how the reflexive practice is characterized, how it evolves through time and how it can be promoted. Data analysis shows that reflexivity is not monodimensional but multidimensional. Reflexive practice increases during the course: The different dimensions vary over time according to different organizational and educational conditions. This methodology allows us to formulate new hypotheses about which elements of the setting and process are effective in supporting participants’ reflexive practice.  相似文献   

Beginning teachers as enquirers: m-level work in initial teacher education     

Beth Dickson 《欧洲师范教育杂志》2011,34(3):259-276

In order to deliver life-long learning for teachers, practitioner-based enquiry learning is being promoted by teacher education institutions on the basis that this form of learning gives teachers the ability to understand factors affecting learning within their own classrooms by systematic investigations of issues and the construction of an evidence-base on which decisions which improve learning can be taken. In turn this enhances teacher professionalism. This article presents a study of how practitioner-based enquiry was embedded in an initial teacher education programme; the reasons for this; and the purposes of the strategy, which raised the one-year postgraduate qualification to masters-level. It looks at the reasons for the change; the nature of the change, which included educating teachers intending to teach in primary schools together with those intending to teach in secondary; the introduction of practitioner-based enquiry; some early student reaction; and the structural, cultural and learning issues which have emerged.  相似文献

Further developing the library curriculum: skills for life delivery     

Coysh L 《Health information and libraries journal》2011,28(1):82-86

This feature discusses how the library curriculum was developed at Plymouth Hospitals NHS Trust Library Service to aid the delivery of Skills for Life. In particular, the feature describes how, through collaboration with learndirect, literacy and numeracy skills were embedded into the broader library and information skills training programme. The article reports on how the programme resulted in the provision of qualifications and skills development opportunities to NHS staff, and an increase in the NHS library profile.  相似文献

Countermovement jump performance assessment using a wearable 3D inertial measurement unit     

Picerno P  Camomilla V  Capranica L 《Journal of sports sciences》2011,29(2):139-146

The aim of this study was to validate a wearable inertial measurement unit (IMU), containing a 3D accelerometer and gyroscope, for the estimation of countermovement jump height. The absolute vertical acceleration of the IMU positioned on the back of the participant at L5 level, compensated for trunk rotations, was used to obtain jump height by applying the equation of free-fall to the motion of the IMU. The methodology was tested on 28 participants performing five countermovement jumps each. A reference value for this quantity was obtained using stereophotogrammetry (35.4 cm, s = 4.9). Jump height scores obtained using the proposed methodology (35.9 cm, s = 5.5) presented no significant difference with respect to stereophotogrammetry (P = 0.61). A low bias of 0.6 cm confirmed the accuracy of the estimate, which also showed a high (r = 0.87) and significant (P < 0.0001) correlation with reference values. Furthermore, without compensating accelerations for trunk rotation, jump height was largely underestimated (P < 0.0001) (bias: -12.7 cm) and poorly associated (r = 0.31) with stereophotogrammetry. The results of this study show that the estimation of jump height using inertial sensors leads to accurate results when the measured accelerations are corrected for trunk rotations.  相似文献
