[目的/意义]为了将大数据更好地用于循证决策,文章构建了循证决策视角下的患者健康主题分析模型。[方法/过程]首先使用LDA主题模型对高血压问答数据进行主题探测,并结合文献提炼出高血压八大主题;再次使用问卷调查法和层次分析法对主题探测结果进行评估;最后对得到的证据进行实践讨论。[结果/结论]文章对大数据和循证决策的结合做了尝试性探索,结果表明循证决策视角下的患者健康主题分析模型,具有一定的实用性和创新性。     

大学英语写作中教师书面反馈的实效性研究

教师书面反馈是否有效？哪种形式更有效？这一直是二语写作和二语习得研究领域备受争议的话题。本研究对非英语专业4个平行班的60名学生分别给予直接反馈、划线＋代码提示反馈、错误划线反馈、零反馈,通过定性与定量分析,探讨4种模式对大学英语高、中、低不同层次学生的写作水平产生的影响。研究结果发现,书面反馈对非英语专业学生英语写作水平的提高是有成效的,且不同层次（高分组、中分组、低分组）学生写作能力的提高幅度与书面反馈的模式密切相关。

A multi-criteria approach for the group assessment of an academic course: A case study

The present paper aims at proposing a structured methodology to evaluate the results of an academic training course addressed to postgraduate students. The evaluation process intends to identify the efficacy of an education course by means of a comparison between the general objectives and the results expected by the students. Since the evaluated aspects by the students, detected by means of questionnaires, are both quantitative and qualitative, the proposed methodology is based on the analytic hierarchy process (AHP). In order to facilitate the evaluation process, answers have been modelled by means of linguistic variables. In particular, different evaluation scales have been used and each one is characterized by different levels associated to different fuzzy numbers.     

自主与合作学习模式下英语听说能力的培养

教育部对非英语专业学生听说能力提出了新要求,然而许多高校的大学英语教学却因办学规模扩大不得不实行大班授课,大学英语听说教学改革势在必行。通过一个学年的听说教学实践活动,证明了自主与合作相结合的学习模式有助于激发学生的学习兴趣,培养学生的合作能力和自主学习能力,提高学生整体的听说水平。     

问题解决内涵的重构——来自PISA的启示

国内关于问题解决的探讨有很多,但并没有达成普遍共识。PISA2003的一大亮点就是第一次对15岁学生在问题解决项目中的表现做了深度考察,并对问题解决的内涵做了明确界定,有很强的可操作性,值得我们借鉴。     

Reading and spelling difficulties in high school students: Causes and consequences

Basic skills in reading and spelling and supporting metalinguistic abilities were assessed in ninth and tenth grade students in two school settings. Students attending a private high school for the learning disabled comprised one group and the other comprised low to middle range students from a public high school. Both the LD students and the regular high school students displayed deficiencies in spelling and in decoding, a factor in reading difficulty that is commonly supposed to dwindle in importance after the elementary school years. Treating the overlapping groups as a single sample, multiple regression analysis was used to investigate the contribution of nonword decoding skill and phonological and morphological awareness to spelling ability. The analysis revealed that decoding was the major component, predicting about half of the variance in spelling. The effect of phonological awareness was largely hidden by its high correlation with decoding, but was a significant predictor of spelling in its own right. Morphological awareness predicted spelling skill when the words to be spelled were morphologically complex. An additional study showed that differences in decoding and spelling ability were associated with differences in comprehension after controlling for reading experience and vocabulary. Even among experienced readers individual differences in comprehension of text reflect efficiency of phonological processing at the word level.     

基于层次分析法的公共体育服务评价体系构建

本文基于文献研究的方法,首先表述了公共体育服务的研究背景、目的和意义,并进一步讨论了公共体育服务评价的相关逻辑架构以及政府机构在体育公共服务方面影响的关键内容。然后通过由有关专家对各指数做出“重要性”和“可操作性”两个层次的评价,得出相应的结论,并使用SPSS统计分析应用软件进行均值数和变化系数,最终确立了6个指标。最后基于层次分析法建构了体育公共服务评价体系,并根据结果分析给出了相关改进建议。
