本文基于国外学者对形成性评估效度和信度理论的研究,提出适用于形成性评估的效度验证框架。本框架采用Messick(1989)的"整体效度观",把形成性评估的效度界定为,评估结果的解释和使用是否和在多大程度上真正促进了学生学习的进步?效度验证应当从评估的构念、任务、过程、结果的解释和使用、后果和课堂环境等方面收集证据。参照BachmanPalmer(2010)的AUA模式,本框架明确了效度验证所要回答的问题及其研究方法。 相似文献

大学英语四级考试是一项能力测试。在能力测试中,信度和效度是评估大学四级考试的两个主要标准。测试的成功与否,在很大程度上取决于这两个标准的高低,因而应力争提高其测试的信度与效度。分析改革后四级考试听力部分的信度和效度对大学英语听力教学也有一定的指导意义。 相似文献

考试效度指考试对考试构念进行测量的有效程度,效度研究指的是为解释考试分数而收集效度证据的过程。英语水平考试旨在测量考生的英语语言水平,本文以公共英语等级考试PETS一5为样卷,以考试题目和语言能力等级关系量表（Linking Test Questions to Task Statements）为工具,采用专业人士的分析评判为主要研究方法,收集基于考试内容的效度证据,对英语水平考试的效度研究方法进行了初步探索。 相似文献

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help? 相似文献

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love. 相似文献

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities. 相似文献

During interview with English majors, it was found that a majority of students expressed disappointment with their experience of English literature classes. Students' dislike of learning English literature appears to be the major problem of teaching English literature in China. Reader response approach is a good way to solve this problem. In this paper, I explain the rationale behind the reader response approach, such as its origin, definition, features, assumptions, and strategies. Then I illustrate how reader response approach works as a teaching strategy by presenting several teaching models. At last I evaluate its usefuiness for teachers and present the advantages of reader response approach in Chinese context. 相似文献
