‘Would you like to tidy up now?’ An analysis of adult questioning in the English Foundation Stage

This study provides an extension of analysis concerned with adult questioning carried out in the Researching Effective Pedagogy in the Early Years (REPEY) study. The REPEY study drew on robust quantitative data provided by the Effective Provision of Pre‐School Education (EPPE) project to identify the particular pedagogical strategies being applied by more effective pre‐school settings to support the development of the skills, knowledge and attitudes that enable their children to make a good start at school. Following a line of investigation identified in the EPPE analysis, and supported by previous studies, REPEY included a preliminary analysis of the forms of questioning applied by early childhood practitioners. These findings were based on 1967 adult questions identified in a random sample of four half‐day observations drawn from each of the 12 pre‐school settings that were identified by EPPE as more ‘effective’. In this extension of the analysis a text search of the N‐Vivo database identified a total of 5808 questions across the full 400 hours of observations of 28 staff that were recorded in 2000–2001. The aim of the research has been to provide a more thorough analysis of the forms of questioning applied, and to investigate the possibility that the use of open‐ended forms of questioning might be particularly supportive in early childhood development. Surprisingly, it was found that 94.5% of all the questions asked by the early childhood staff were closed questions that required a recall of fact, experience or expected behaviour, decision between a limited selection of choices or no response at all. Only 5.5% were open‐ended questions, which provided for increased encouragement (to speculate and trial and error) and/or potential for sustained, shared thinking/talking. This article provides an account of the analysis and the authors' coding and rationale for the seven types of closed questions and four types of open‐ended questions that are most commonly asked by early years staff.

硝苯地平缓释胶囊释放度方法的建立

目的：建立硝苯地平缓释胶囊的释放度检查方法。方法：以盐酸溶液（9→100mL）1000mL溶出介质,转速为60r.min-1,取样时间为1h,4h,8h,采用释放度第一法,溶出度第二法测定。结果：硝苯地平在1.834-22.008μg.mL-1的浓度范围内,线性相关性良好。线性方程为：A=70580.3C-4008.4（r=0.9999）;平均回收率为100.4%,（RSD=1.14%）;6批样品在1h,4h,8h的释放量分别为标示量的15%-40%,30%-65%,50%-80%。结论：本方法便捷、准确、重现性好,可用于硝苯地平缓释胶囊的质量控制。
