错题深加工：“轻负担、高质量”教学的有效路径

错题本身是一种学习资源,而且是为学习者量身定做的资源,对错题进行深加工,有助于实现＂轻负担、高质量＂的教育愿景。对于学生来说应建立错题本、错因归类、善于反思、多种利用方式并举;对于教师来说应以错定教,善于运用多种教学策略,加深正解思维的深刻性。     

The effect of anticipated achievement feedback on students' semantic processing as indicated by the N400 cloze effect

The present study examined the effects of anticipated achievement feedback on students' semantic processing on the neural level, using event-related brain potentials (ERPs). Participants (N = 79) anticipated either self-referential or normative achievement feedback regarding an announced upcoming test. Additionally, their performance expectations (low vs. no expectations) were orthogonally manipulated. Subsequently, students' on-line semantic processing was assessed by measuring the N400 cloze effect, a component in the EEG signal of which the amplitude is associated with semantic processing. Within the low performance-expectation condition, no effect of anticipated feedback on semantic processing was found. Within the no-performance-expectation condition, participants anticipating self-referential feedback showed a more widely distributed N400 cloze effect than participants anticipating normative feedback. The results confirmed the hypothesis that the mere expectation of a particular type of feedback can affect students' semantic processes.     

Writer identification approach based on bag of words with OBI features

Handwriter identification aims to simplify the task of forensic experts by providing them with semi-automated tools in order to enable them to narrow down the search to determine the final identification of an unknown handwritten sample. An identification algorithm aims to produce a list of predicted writers of the unknown handwritten sample ranked in terms of confidence measure metrics for use by the forensic expert will make the final decision.Most existing handwriter identification systems use either statistical or model-based approaches. To further improve the performances this paper proposes to deploy a combination of both approaches using Oriented Basic Image features and the concept of graphemes codebook. To reduce the resulting high dimensionality of the feature vector a Kernel Principal Component Analysis has been used. To gauge the effectiveness of the proposed method a performance analysis, using IAM dataset for English handwriting and ICFHR 2012 dataset for Arabic handwriting, has been carried out. The results obtained achieved an accuracy of 96% thus demonstrating its superiority when compared against similar techniques.     

Exploring mechanisms of rapid automatized naming to arithmetic skills in Chinese primary schoolers

Rapid automatized naming (RAN) is associated with children's arithmetic performance, which is multifactorial by nature and consists of arithmetic fluency, arithmetic procedure, and word problems. Yet, it is unclear whether RAN can predict all key aspects of arithmetic skills independently and what cognitive mechanisms may explain this relation. Using a sample of Chinese primary school students (N = 170), results showed that while RAN was associated with all key aspects of arithmetic skills, the relations of RAN–arithmetic procedure and RAN–word problems may be dependent on that of RAN–arithmetic fluency. Supporting the processing speed hypothesis, results further suggested that processing speed may underlie the relation between RAN and arithmetic performance. Findings made unique contribution to understanding the effect of RAN on arithmetic performance and cognitive mechanisms that may underpin this association in the context of Chinese culture.

济慈的诗歌——现实主义和浪漫主义的完美结合

众所周知，作为英国学史上第二代浪漫主义诗人的杰出代表之一的济慈，其诗歌不论在形式上还是在内容上都给人留下了美的享受。然而在他的相当一部分的作品里。诗人同时采用浪漫主义和现实主义的表现手法进行创作，既艺术地描写美好的理想生活。又真实地再现当时的社会生活。本将结合诗人的某些诗篇。重点分析诗歌中的现实主义特点。     

中国古代文学中雁意象的文化内蕴

雁 ,是中国古代文学中常见的意象之一。在文学作品中 ,古人常以雁自喻 ,抒写内心的思乡怀旧、羁旅孤苦之情 ,以及相思哀怨的感伤 ,成为道德伦常的载体。雁意象丰富的文化内蕴 ,相沿承袭 ,给传统抒情文学和民族审美心理产生不可忽视的影响     

意象——诗歌表达的另一种语言

中国古典诗歌具有隐约幽微、意在言外的特点，是因为它运用词句营造出第二层次的符号系统．这一系统以意象为主。意象具有独立的表迭功能，但其所指更不确定，这就使诗歌更加隐晦。古典诗歌还借助文学传统和文化背景表情迭意，这更丰富了诗歌内涵，也使诗歌理解起来更为见仁见智。     

从诗话角度看中西诗歌意象

诗歌中一个重要的创作手段是通过意象来表达诗人的情怀。中英文诗歌在意象的作用、营造手法、选择意象之物等方面具有共同点,但由于各民族不同的自然环境、社会背景和风俗习惯,表述时所选择的意象之物又不尽相同。从诗话角度出发,通过对中英文诗歌中的意象进行对比研究,我们发现它们之间的差异与中西美学的不同呈现出同一态势。
