NCME 2007 Presidential Address: The Concordance Table: An Invitation to Misuse Test Scores

This article discusses a particular type of concordance table and the potential for test score misuse that may result from employing such a table. The concordance that is discussed is typically created between scores on different, nonequatable versions of a test that share the same or close to the same test title. These concordance tables often appear in the context of relating scores on computerized adaptive and paper‐and‐pencil versions of the same test. When such a table is presented in a complete point‐by‐point fashion, relating each reported score on the scale of the new version of the test to a reported score on the scale of the old version of the test, test score users will typically treat the table as if it represented an equating of scores between the two versions, and directly replace scores on the new version of the test by scores on the old version. This clearly represents a misuse of the test scores. Suggestions for avoiding this misuse of test scores from concordance tables are provided.     

浅谈“读者剧场”在大学英语口试中的运用

随着经济和社会的发展,英语口语越来越受到学生的重视,大学英语教学改革必须要“以人为本”“与时俱进”,所以在大学英语期考中增加口试是十分必要的,它激励学生在平时学习中要注重锻炼自己的口语。教师将“读者剧场”运用到口试中,不仅可以增加测试本身的趣味性,也能提高学生综合语言素质。本文对大学英语口试和“读者剧场”进行分析,从两者特点出发,探寻二者结合的优势之处,以及教师在实施“读者剧场”过程中的注意事项。     

基于工作过程的“土工实训”课程学习情境开发与设计

按照高等职业教育各专业人才培养方案,充分利用土木行业各方面的优势,坚持将课程标准和岗位能力标准相结合的基本原则,根据土木工程行业的需求、发展和职业岗位对应的工作任务所要求的素质、能力、知识等方面需求,突出实践与理论相结合;基于工作过程“土工实训”课程学习情境开发与设计充分地展示高等职业教育教学改革的特点,强调循序渐进和将理论应用于实践,较清晰明了地进行课程设计。通过根据调研土工试验员岗位职责开展课程体系的开发与建设,确定主要课程教学内容,以现场土工试验员的工作过程为主线,确定符合目前我国各施工单位的土工试验员的工作岗位所必需实用的知识与技能。使用基于工作的开发理念与思路,来完成“土工实训”课程的各部分的教学内容,通过教学改革使课程培养目标与实际工作需要相符合。     

高中生人格特质、时间管理系倾向与考试焦虑的关系

目的：探讨人格特质、时间管理系倾向与考试焦虑的关系。方法：以青少年时间管理倾向量表（ATMD）、艾森克人格问卷简式量表中文版（EPQ-RSC）、考试焦虑量表（TAS）对584名高中生进行调查。结果：TAS总分与时间管理倾向总分、时间价值观、人格特质中的N神经质呈十分显著的正相关（p＜0.01）。以上三个因素对考试焦虑预测效果显著。结论：时间管理倾向、时间价值观、人格特质中的N神经质与考试焦虑高低存在紧密的联系,具有将强的预测力。     

高技术产业成长与科研人才的关系研究

选取1996—2012年我国高技术产业总产值和RD人员的数据,采用协整分析和格兰杰因果检验分析,对我国高技术产业产业成长与科研人才关系进行验证,并建立了二者的误差修正模型。结果表明:二者存在长期的动态均衡关系,科研人才是高技术产业成长的格兰杰原因。这说明在我国高技术产业的成长期,二者没有形成良性的双向作用关系。

Determination of Biological Variance and Validation of a Fluorometric Assay for Measurement of α-l-Iduronidase Activity in Dried Blood Spots Samples: The First Experience in Iran

Methods for assaying lysosomal diseases in dried blood samples are very useful today due to its several advantages related to the stability of samples, its transportation, handled and analysis, and its potential use for newborn screening compared to traditional methods in leucocytes samples. For this reason, it is important to validate these assays before being used in routine laboratory. Because of different in biological markers based on ethnicity, we aimed this study to validation a DBS-based fluorometric assay for measurement of α-l-Iduronidase activity for diagnosis of MPS I patients in Iran. DBS samples were collected from 15 MPS I patients and 60 healthy age matched subjects. Diagnostic value, biological variance and α-l-Iduronidase activity were determined. DBS α-l-Iduronidase activity was significantly higher in male subjects than in female group. Using a cut-off level of 1.08 µmol/spot 20 h, sensitivity and specificity were 100 and 98 %. The linearity of test was proved and we showed that within-run and between run precision were 5.6 and 14.66 %. Measurement of α-l-Iduronidase activity in DBS samples is an accurate test for diagnosis of MPS I and because of its rapid shipping and simplicity to keeping, DBS-based enzyme activity could be considered as a useful diagnostic tool in this disease.
