Teaching principles of inference with ANOVA

Analysis of variance (ANOVA) is a test of mean differences, but the reference to variances in the name is often overlooked. Classroom activities are presented to illustrate how ANOVA works with emphasis on how to think critically about inferential reasoning.     

The impact of immediate test score reporting on university students' achievement emotions in the context of computer-based multiple-choice exams

Test-taking is an emotion-laden event for many students. Typically, negative emotions are highest at the start of an examination and are replaced by positive emotions as the exam progresses. The impact of computer-based testing and immediate score reporting on students' emotions has not been examined. In Study 1, we evaluated university students’ emotions at the end of a computer-based exam and found positive emotions more strongly endorsed than negative. In Study 2, we replicated this finding and used a quasi-experimental pre-post design to examine how emotions changed in response to real examination scores. Exam scores presented immediately had significant positive effects on relief, pride, and hope and negative effects on anxiety and shame even after controlling for the corresponding emotion at the end of the exam. The one exception was anger, which was not impacted by examination score. No interaction effects were found.

对恢复高考英语听力测试的思考

自2000年以来,我国开始在高考英语试题中逐渐推广听力测试,2003年高考英语听力测试在全国普及,促进了基础教育阶段学生英语听力水平的提高。但2005年起出现了部分省区取消或淡化高考英语听力的现象。本文探讨了此举的原因、危害,建议尽早恢复高考英语听力测试,发挥高考对基础英语教育的正面反拨作用,为培养学生的英语交际能力打下基础。     

Predictive value of ventilatory inflection points determined under field conditions

The aim of this study was to evaluate the predictive potential provided by two ventilatory inflection points (VIP₁ and VIP₂) examined in field without using gas analysis systems and uncomfortable facemasks. A calibrated respiratory inductance plethysmograph (RIP) and a computerised routine were utilised, respectively, to derive ventilation and to detect VIP₁ and VIP₂ during a standardised field ramp test on a 400 m running track on 81 participants. In addition, average running speed of a competitive 1000 m run (S_1k) was observed as criterion. The predictive value of running speed at VIP₁ (S_VIP1) and the speed range between VIP₁ and VIP₂ in relation to VIP₂ (VIP_SPAN) was analysed via regression analysis. VIP_SPAN rather than running speed at VIP₂ (S_VIP2) was operationalised as a predictor to consider the covariance between S_VIP1 and S_VIP2. S_VIP1 and VIP_SPAN, respectively, provided 58.9% and 22.9% of explained variance in regard to S_1k. Considering covariance, the timing of two ventilatory inflection points provides predictive value in regard to a competitive 1000 m run. This is the first study to apply computerised detection of ventilatory inflection points in a field setting independent on measurements of the respiratory gas exchange and without using any facemasks.     

增设半决赛对蹦床比赛成绩特征的影响

近两个奥运周期国际体联在蹦床比赛评分规则上做出了较大的修订和调整,增加飞行时间评分指标,提高蹦床器材弹性以及修改赛制增加半决赛。研究认为:增设半决赛给赛事带来了更多不确定性,提高了比赛的惊险性和观赏性;对成绩排名造成了一定影响,竞争格局发生变化;增设半决赛即在更高、更难的基础上,对运动员的技术、心理等各方面稳定性都提出了更高要求;男、女网上个人项目的不确定因素有所不同,应根据不同情况调整策略,处理好难度、技术和高度的辩证关系,以求收益最大化。     

从教学条件看信息技术教育的发展

通过对浙江省嘉兴、湖州两个地区部分中学的抽样调查,从教材和课时、教学设备、师资力量等多个方面分析我国中小学信息技术教育的现状.在分析过程中,除一般的对比说明外,还运用了Excel数理分析中的假设检验,对该学科在教学条件方面存在的问题做进一步揭示,并提出一些可行性建议.     

深广、凄绝两由之--从《虞美人》和《武陵春》看李煜和李清照的愁

李煜的<虞美人>和李清照的<武陵春>历来受人推崇,被认为是写愁词的千古绝调. 从此中可略窥其抒愁风格之一斑.真是作之凄然,读之怆然.就两人前后际遇的迥异,两首词内容和表现手法的分析,男女词人的不同情感表现来探讨二人的言愁,其愁各有千秋,深广、凄绝两由之.但基调和意蕴均一样荡人心魂,具异曲同工之妙.     

外语测试的形成性评价观

外语测试经历了以语码为纲和以结构为纲的两个时期。现行的外语测试则遵循“以信息为纲”的指导思想。语言测试的结果应能反映学生的语言运用能力，而学生的能力反馈又可常常作为教师的教学反思依据。本文旨在以形成性评价现分析外语测试与评价的一致性和外语测试的多功用性。
