Adventures with the globe: Early childhood geography     

Mary E. Haas  Bobbie Gibson Warash 《Early Childhood Education Journal》1989,17(2):10-13

Do you know which continent looks like an ice cream cone, a capitalA, or a frowning face? Just ask the four-year-olds at the West Virginia University Nursery School, and they'll tell you. Learning the names and shapes of the continents was part of their studies about the globe.  相似文献   

School Resources in Teaching Science to Diverse Student Groups: An Intervention’s Effect on Elementary Teachers’ Perceptions     

Okhee Lee  Lorena Llosa  Feng Jiang  Corey O’Connor  Alison Haas 《Journal of Science Teacher Education》2016,27(7):769-794

Elementary school teachers’ perceptions of school resources (i.e., material, human, and social) for teaching science to diverse student groups were examined across three school districts from one state. As part of a 3-year curricular and professional development intervention, we examined the effect on teachers’ perceptions after their first year of participation. The study involved 103 fifth-grade teachers from 33 schools participating in the intervention and 116 teachers from 33 control schools. The teachers completed a survey at the beginning and end of the school year. As a result of the intervention, teachers in the treatment group reported more positive perceptions of school resources than teachers in the control group.  相似文献

IntroductionLeukolysis-related pseudohyperkalemia due to preanalytical procedures may lead to erroneous (or absence of) treatment based on an invalid lab test result. We aimed to obtain a leukocyte threshold above which leukolysis-related pseudohyperkalemia becomes clinical relevant. Secondly, temporal dynamics of treatment-induced leukocyte decrease were studied to allow tailored implementation of laboratory information system (LIS) decision rules based on the leukocyte threshold to avoid leukolysis-related pseudohyperkalemia.Materials and methodsPotassium results of AU5811 routine chemistry (Beckman Coulter, Brea, California, USA) and iStat point of care (POC) (Abbott Diagnostics, Chicago, Illinois, USA) analysers were compared, the latter method being insensitive to leukolysis caused by pre-analytical procedures. Potassium results were combined with leukocyte counts obtained using a Cell-Dyn Sapphire haematology analyser (Abbott Diagnostics, Santa Clara, California, USA), resulting in 132 unique data triplets. Regression analysis was performed to establish a leukocyte threshold. The Reference Change Value (√2 x Z x √(CV_a² + CV_i²)) was used to calculate maximum allowable difference between routine analyser and POC potassium results (delta_max + 0.58 mmol/L). Temporal analysis on the treatment-induced leukocyte decrease was performed by plotting leukocyte counts in time for all patients above the threshold leukocyte count (N = 41).ResultsEstablished leukocyte threshold was 63 x10⁹/L. Temporal analysis showed leukocyte counts below the threshold within 8 days of treatment for all patients.ConclusionsBased on performed analyses we were able to implement LIS decision rules to reduce pseudohyperkalemia due to preanalytical procedures. This implementation can contribute to a reduction in erroneous (or absence of) treatments in the clinic.  相似文献
