Developmental cognitive neuroscience highlights the importance of interactions between children and their environment. As young children spend increasing time in childcare, it is key to investigate the impact of “maths‐talk” and maths provisions in preschools. Qualitative insights from early educators indicate a greater bias toward counting activities than would be expected given the Early Years curriculum. In addition, we quantified the observed breadth of preschool practitioners' maths language (e.g., place‐value language), setting‐based maths provisions (e.g., quality of maths‐related activities), and their relation with children's early numeracy skills. In settings with greater practitioners' breadth of maths language, children display greater cardinality skills although our data call for the further investigation of parental socioeconomic status and education. We conclude with a discussion on the need to operationalize children's maths learning environments as diversely as possible. Enriching practitioners' skill sets may be an effective and needed way of improving early maths outcomes.  相似文献   

Examining the impact of four teaching development programmes for engineering teaching assistants*     

Carlton J. Fong  Joanna Gilmore  Tershia Pinder-Grover  Molly Hatcher 《Journal of Further & Higher Education》2019,43(3):363-380

As current graduate instructors of labs and class discussions, teaching assistants (TAs) play a critical role in Science, Technology, Engineering, and Math (STEM) undergraduate education, especially as some graduate students may choose a faculty career in the future. Because of the importance of TAs and their development as scholars and instructors, we sought to determine the most effective methods of preparing engineering TAs at two research universities. We compare the impact of a teaching orientation with one of four teaching development programmes (Pedagogy Course, Advanced Practice Teaching, Workshop Attendance with Written Reflection, or Mid-Semester Student Feedback with Written Reflection) on engineering TAs’ teaching efficacy and definitions of active learning. Results indicated that the Pedagogy Course consistently increased TAs’ teaching efficacy and attitudes toward teaching compared with the other programmes. We also found that stand-alone Mid-Semester Student Feedback with Written Reflection enhanced TAs’ efficacy for reflection and beliefs about teaching. We discuss implications for providing teaching development for graduate students and directions for future research.  相似文献

Sympathetic Behavior in Young Children     

Lois Barclay Murphy 《Journal of Experimental Education》2013,81(1):79-90

Using three stratified random samples of thirty-two teachers each from grades 2 through 5, a 3-group posttest-only control group research design was employed to determine the effectiveness of an in-service program utilizing simulation techniques on teacher awareness of pupils’ instructional reading levels. Pupils were selected randomly from each teacher’s classroom. Differences between the grade level of pupils’ readers and their performance on McCracken’s Standard Reading Inventory constituted the measure of teacher awareness. The importance of teachers’ grade level assignments and the time of year when this in-service training is conducted were also evaluated.

Findings indicated that this in-service program is effective only when conducted before school begins. There was a significant difference in teacher awareness among grade levels but a contravertible one between primary and intermediate levels.  相似文献

Considerations for protein intake in managing weight loss in athletes     

Caoileann H. Murphy  Amy J. Hector 《European Journal of Sport Science》2015,15(1):21-28

Abstract

A large body of evidence now shows that higher protein intakes (2–3 times the protein Recommended Dietary Allowance (RDA) of 0.8 g/kg/d) during periods of energy restriction can enhance fat-free mass (FFM) preservation, particularly when combined with exercise. The mechanisms underpinning the FFM-sparing effect of higher protein diets remain to be fully elucidated but may relate to the maintenance of the anabolic sensitivity of skeletal muscle to protein ingestion. From a practical point of view, athletes aiming to reduce fat mass and preserve FFM should be advised to consume protein intakes in the range of ～1.8–2.7 g kg^?1 d^?1 (or ～2.3–3.1 g kg^?1 FFM) in combination with a moderate energy deficit (?500 kcal) and the performance of some form of resistance exercise. The target level of protein intake within this recommended range requires consideration of a number of case-specific factors including the athlete's body composition, habitual protein intake and broader nutrition goals. Athletes should focus on consuming high-quality protein sources, aiming to consume protein feedings evenly spaced throughout the day. Post-exercise consumption of 0.25–0.3 g protein meal^?1 from protein sources with high leucine content and rapid digestion kinetics (i.e. whey protein) is recommended to optimise exercise-induced muscle protein synthesis. When protein is consumed as part of a mixed macronutrient meal and/or before bed slightly higher protein doses may be optimal.  相似文献   

Augmenting performance feedback does not affect 4 km cycling time-trials in the heat     

Mark Waldron  Vincent Villerius  Aron Murphy 《Journal of sports sciences》2015,33(8):786-794

We compared the effects of (1) accurate and (2) surreptitiously augmented performance feedback on power output and physiological responses to a 4000 m time-trial in the heat. Nine cyclists completed a baseline (BaseL) 4000 m time-trial in ambient temperatures of 30°C, followed by two further 4000 m time-trials at the same temperature, randomly assigning the participants to an accurate (ACC; accurate feedback of baseline) or deceived (DEC; 2% increase above baseline) feedback group. The total power output (PO) and aerobic (P_aer) and anaerobic (P_an) contributions were determined at 0.4 km stages during the time-trials, alongside measurements of rectal (T_rec) and skin (T_skin) temperatures. There were no differences (P > 0.05) in any of the variables between BaseL, ACC and DEC, despite increases (P < 0.05) in T_rec and T_skin. Typical pacing profiles were demonstrated; however, there was no interaction (P > 0.05) between feedback condition and time-trial stage. Providing surreptitiously augmented performance feedback to well-trained cyclists did not alter their performance or physiological responses to a 4000 m time-trial in a hot environment. The assumed influence of augmented performance feedback was nullified in the heat, perhaps reflecting a central down-regulation of exercise intensity in response to an increased body temperature.  相似文献
