从语言测试学角度试析改革后的CET考试

大学英语考试是全国性的用于评估和指导大学英语教学的标准相关常模参照性考试。它对英语的教与学既有积极的促进作用,也有着严重的负面影响。改革后的CET考试在效度、信度、难度以及可操作性上仍然存在着不可忽视的问题。CET考试不仅应信度、效度并重,还应注重考试的可操作性。此外,CET考试中,应该增设口语考试的内容,尽量做到听说读写译加权相当。     

论区域文化格局中的湖州竹文化

竹是湖州地区最为重要的林业资源。湖州人栽培与利用竹子的历史可以追溯到良渚文化时期的钱山漾文明。早在4700多年前,竹即已广泛参与和渗透进湖州先民的日常生产生活当中,且在随后的岁月里,竹的这份参与和渗透愈来愈强大、愈来愈深刻、也愈来愈多元。更其重要的是,自钱山漾文明以降直至当下的漫长历史时空内,竹始终能以其强大的存在,或隐或显地助推湖州区域文化实现一次又一次的新变与转型。换言之,在湖州本土文化的生成与发展历程中,一直伴随着竹子的靓丽身姿和柔美音符,某种意义上甚至可以认为,是竹成就了湖州区域文化。     

《生物药物仪器分析》学习领域课程课业设计的探索

学习领域课程以典型工作任务为载体,其学习内容的组织形式是课业。课业是学习情境的＂物质化＂表现,课业设计在教师作用、学生地位等方面与传统实践教学有明显区别,《生物药物仪器分析》课程对此进行了实践探索。     

论科技风险的产生与治理

现代社会的风险主要源自科技发展副作用所导致的科技风险。科技风险是科技政策研究所不可回避的重要问题。这一问题产生的根源在于科学理性与社会理性的断裂。近年来出现的一种所谓的科技风险民主治理模式已经为解决这一问题提供了一个新的有效途径,而遵循公众参与性、共识性及民主规范性则是现代社会科技风险民主治理的基本原则。

Temporal trends in 6-minute walking distance for older Japanese adults between 1998 and 2017

BackgroundThe 6-minute walking distance (6MWD) is an excellent measure of both functional endurance and health. The primary aim of this study was to estimate temporal trends in 6MWD for older Japanese adults between 1998 and 2017; the secondary aim was to estimate concurrent trends in body size (i.e., height and mass) and self-reported participation in exercise/sport.MethodsAdults aged 65–79 years were included. Annual nationally representative 6MWD data (n = 103,505) for the entire period were obtained from the Japanese Ministry of Education, Culture, Sports, Science and Technology. Temporal trends in means (and relative frequencies) were estimated at the gender–age level by best-fitting sample-weighted linear/polynomial regression models, with national trends estimated by a post-stratified population-weighting procedure. Temporal trends in distributional variability were estimated as the ratio of coefficients of variation.ResultsBetween 1998 and 2017 there was a steady, moderate improvement in mean 6MWD (absolute = 45 m (95% confidence interval (95%CI): 43–47); percent = 8.0% (95%CI: 7.6%–8.4%); effect size = 0.51 (95%CI: 0.48–0.54)). Gender- and age-related temporal differences in means were negligible. Variability in 6MWD declined substantially (ratio of coefficients of variation = 0.89, 95%CI: 0.87–0.92), with declines larger for women compared to men, and for 75–79-year-olds compared to 65–74-year-olds. Correspondingly, there were moderate and negligible increases in mean height and mass, respectively, and negligible increases in the percentage who participated in exercise/sport at least 3 days per week and at least 30 min per session.ConclusionThere has been a steady, moderate improvement in mean 6MWD for older Japanese adults since 1998, which is suggestive of corresponding improvements in both functional endurance and health. The substantial decline in variability indicates that the temporal improvement in mean 6MWD was not uniform across the distribution. Trends in 6MWD are probably influenced by corresponding trends in body size and/or participation in exercise/sport.     

物理核心素养评价与学业质量检测的研究

物理是初中阶段的重要课程,也是学生对世界进行基本科学认知的引导课程.在学生系统学习了近两年的物理后,学校和教师应对学生进行物理核心素养评价和学业质量检测.在物理核心素质评价与学业质量检测中,只有从物理观念、科学探究、科学思维、科学态度与责任入手,才能让评价与检测全面、丰富和多元.
