Students’ achievement goals and beliefs of causes of success: Temporal relations and gender differences     

《Contemporary educational psychology》2021

According to the goal orientation model, students’ achievement goals and beliefs are interrelated. Within this framework, research and theory have so far assumed that achievement goals are associated with students’ beliefs of causes of success, the latter representing students’ subjective beliefs about the factors contributing to success at school. So far, this line of research has been restricted to a few cross-sectional studies. We examined the temporal relations between achievement goals (mastery, performance-approach, and performance-avoidance goals) and students’ beliefs of causes of success, the latter operationalized by asking the students to rate the subjective importance of diligence, effort, and ability for school success. Achievement goals and beliefs of causes of success were measured twice with a time lag of one school year with a sample of N = 2044 German secondary school students. Cross-lagged panel models were estimated to examine the temporal relations between achievement goals and beliefs of causes of success while controlling for students’ secondary school track, socio-economic status, and Grade Point Average. Former mastery goals were found to be positively related to later importance ratings of diligence for school success; former performance-approach goals were found to be positively related to later importance ratings of ability. Boys and girls were found to display similar relations among constructs but they showed differential mean levels on both the achievement goal constructs and the beliefs of causes of success. Implications for research on achievement goals and practice using intervention approaches are discussed.  相似文献   

Dictionary-based text categorization of chemical web pages     

Chun-Yan Liang  Li GuoZhao-Jie Xia  Feng-Guang NieXiao-Xia Li  Liang SuZhang-Yuan Yang 《Information processing & management》2006

A new dictionary-based text categorization approach is proposed to classify the chemical web pages efficiently. Using a chemistry dictionary, the approach can extract chemistry-related information more exactly from web pages. After automatic segmentation on the documents to find dictionary terms for document expansion, the approach adopts latent semantic indexing (LSI) to produce the final document vectors, and the relevant categories are finally assigned to the test document by using the k-NN text categorization algorithm. The effects of the characteristics of chemistry dictionary and test collection on the categorization efficiency are discussed in this paper, and a new voting method is also introduced to improve the categorization performance further based on the collection characteristics. The experimental results show that the proposed approach has the superior performance to the traditional categorization method and is applicable to the classification of chemical web pages.  相似文献

试论"程度词+名词"结构中的名词语义特征     

李学军 《安阳工学院学报》2005,(1):121-123

"程度词 名词"虽是一类很特殊的结构,但已具有相当程度的可接受性.与一般意义上的名词不同,进入这一结构中的名词需具有由具体指称向情状描述转化的潜在语义特征.这类名词与程度词的组合弥补了形容词语义表达上的缺失问题,并由此引发了部分名词向名形兼类词的转变.  相似文献   

古汉语谦敬称谓词类的词性探讨   总被引：1，自引：0，他引：1  

李冬香 《广东技术师范学院学报》2003,(3):53-56

古汉语谦敬称谓词类的词性，有两种不同的看法：代词说和名词说。通过全面考察，我们发现它们的语法功能、语义演变、代替作用等，都同名词基本相同，而与代词相距较远。因此，它们应该归属于名词。仅仅因为其代替作用就把它们归为代词是不恰当的，我们应该考虑其整体特点。  相似文献

隐喻不仅是一种修辞方法,更是一种认知方式,它反映了不同文化背景下人们认识世界的不同方式。在彼得.纽马克提出的极具个人特色的表达型文本中的隐喻现象的翻译在整个翻译过程中尤为重要,必须根据实际情况,适当地选择语义翻译和交际翻译相结合的方法,以获得最具语用价值的译文。  相似文献   

语义图在英语阅读中的运用     

赵苗  郑文兰 《安康学院学报》2006,18(3):115-117

在英语教学中构建语义图,是引导学生深入理解文章的一个有效方法。语义图的各层次分别包括学生对相关主题的联想、篇章的背景知识、文章的重点内容等。因此,可以激励学生在课前主动搜索相关知识、积极加入课堂讨论,并在教师的引导下一步步理解文章内容。除了在阅读方面的作用,语义图也是进行听力、口语、写作等方面训练的有效辅助手段。  相似文献
