语义异常的不同阐释路径     

李翠英 《重庆师专学报》2011,(5):104-108

语义异常在语言中是昔遍存在的现象,虽处于学术研究的边缘,却也一直散见于各种语义学论著中。文章通过对各语义学流派不同观点的梳理,将语义异常现象的分析划分为三种路径：形式的、语用的和认知的,同时指出各路径的特点和不足。  相似文献   

论Leech的语义七分法对英语词汇教学的启示     

陈达芬 《福建师大福清分校学报》2011,(3):67-70,76

英语词汇教学是英语教学中的一个重要组成部分。本文针对英语词汇学习中存在的主要问题即缺乏对词义的正确理解而导致词汇误用的现象,提出运用Leech的词义七分法理论指导英语词汇教学,以期使学生正确理解词的意义和用法,提高词汇的运用能力。  相似文献   

基于语料库的fairly和rather语义韵对比分析     

梁卫霞 《牡丹江教育学院学报》2011,(4):31-32

日语同一汉字不同音读间的语义关系考察——兼与汉语比较     

张晓东 《浙江教育学院学报》2011,(6):7-12

日语中存在同一汉字有不同音读的现象,这给日语学习者在词汇习得上造成了一定的障碍。通过对单个汉字音读间的语义区别、不同音读与字频关联性的分析考察,探讨同一汉字不同音读间的语义关系。新发现14个日语常用汉字存在不同音读间语义区别明显的情况。语义丰富词汇多的汉字中容易出现不同音读,而语义单一词汇少的汉字中读音趋于统一。  相似文献   

现代汉语介词配价结构探析     

闫克 《南阳师范学院学报》2011,10(11):61-65

现代汉语介词是一种具有配价能力和配价要求的特殊虚词。与动词配价结构相比,介词的配价结构在句法上具有非独立性,在语义上具有非自足性,是句子深层中的次谓语。介词的配价成分在数量上一般是两个,通常表现为句子的主语和介词的宾语,其中后项配位倾向于由时间、地点、工具等非核心语义角色充当。  相似文献   

Expectancy value interactions and academic achievement: Differential relationships with achievement measures     

《Contemporary educational psychology》2019

Motivation predicts academic achievement beyond cognitive ability. Expectancy value theory (Eccles et al., 1983) is a widely accepted and powerful approach explaining academic achievement as well as educational choices and attainment. Recently, attention to the multiplicative term of expectancy and value beliefs has increased. Trautwein et al. (2012) reported a detrimental effect of high task value when expectancy beliefs were low. We aimed to replicate and extend their study by using a large, representative sample of students attending upper secondary school in the German federal state Schleswig-Holstein (N = 3367). Following Trautwein et al. (2012), we applied latent interaction modelling to test whether the predictive value of expectancy value interactions differs for grades, final examinations, and standardized test scores as measures of achievement in two domains. We took the multi-dimensional structure of task value into consideration, analyzing the four components (attainment, intrinsic value, utility and cost) separately. Both a verbal and a non-verbal domain (English as a foreign language and mathematics) were investigated. Overall, the results supported those of Trautwein et al. (2012). However, our findings suggested measure- and domain-specific differences when using expectancy value beliefs and their interactions to predict academic achievement. Interaction terms predicted final examination results in both English and mathematics. Further, interaction effects were significant for grades in English but not mathematics. In general, effect sizes of multiplicative terms were small, especially in contrast to expectancy beliefs. Findings are discussed regarding the practical and conceptual importance of the multiplicative term in expectancy value theory applied in an educational setting.  相似文献   

Theoretical and methodological implications of associations between executive function and mathematics in early childhood     

《Contemporary educational psychology》2019

Despite agreement about the importance of executive function (EF) for children’s early math achievement, its treatment in correlational studies reflects a lack of agreement about the theoretical connection between the two. It remains unclear whether the association between EF and math operates through a latent EF construct or specific EF components. Specifying the correct measurement model has important theoretical implications for the predicted effects of EF interventions on children’s math achievement. In the current study, we tested whether associations between EF and math operate via a latent EF factor, or via specific EF components using data from a large, nationally representative sample. We then replicated these same analyses with a meta-analytic database drawn from ten studies that collected measures of children’s EF and math achievement. Our results lend support to explanations that a single EF factor accounts for most of the EF component-specific associations with math achievement. We discuss theoretical and methodological implications of these findings for future work.  相似文献
