从高级英语看隐喻词汇的认知意义

高级英语课是英语专业高年级的一门主干课程,其目的是为了帮助学生的英语水平有一个质的飞跃,而词汇在该课程的教学中起着举足轻重的作用。运用认知语言学的新成果—─隐喻概念,探讨了隐喻与思维、隐喻与词汇的关系以及高级英语课中隐喻词汇的认知意义,这对于指导学生准确地理解并使用英语词汇,从而促使其隐喻能力的形成无疑具有积极的指导意义。     

试论发展性教师评价的理念、过程和主要方法

发展性教师评价在评价理念方面，坚持以促进教师发展为主要目的，鼓励教师积极参与评价，注重动态、形成性评价，强调把交流、研讨贯穿于评价过程，重视教师评价的个别差异性。发展性教师评价主要以教师自我评价、同事相互评价及多主体综合评价等为主要方法。发展性教师评价倡导简便易行的评价标准，强调把握评价的切人点，使评价成为教师日常教育教学活动的组成部分。     

大学生社会主义荣辱观教育要正确处理的几个关系

对大学生进行社会主义荣辱观教育必须正确处理以下五个方面的关系:一是大力弘扬与精心培育的关系,二是理论辩伪与实践体验的关系,三是正面典型引导与反面案例启迪的关系,四是教师以身作则与严格要求学生的关系,五是价值导向与制度安排的关系。     

模糊概念:语际转换中的障碍性因素

语言主体认知机制的局限性决定了模糊概念的客观存在性。受所指概念模糊性的影响，原语模糊词与其译语对应体（精确词或模糊词）无法实现完全对应的转换关系。双语所指概念应用区域不能完全重舍是造成模糊词语际转换障碍的主要原因。

资本批判视角下的科学发展观探析——基于马克思《1844年经济学哲学手稿》资本批判的思考

中国特色社会主义与资本在中国的回归、成长有着密切关系。学会科学地驾驭资本,是贯彻落实科学发展观必须直面的问题。马克思在《1844年经济学哲学手稿》批判了对待资本的三种旧哲学思维方式,即客体化思维、直观思维和纯粹精神抽象思维,确立了自己对资本的独特理解,即要从人的感性活动、实践活动来理解资本。当代中国社会同时存在发展不足和畸形发展的问题,前现代、现代、后现代三类异质性问题同时存在,贯彻落实科学发展观,必须拒绝任何对资本主导下的现代性基本原则作出脱离实际历史运动的抽象肯定或抽象否定,反对资本永恒论和资本万恶论。     

Extraction of novel features for emotion recognition

Hilbert-Huang transform method has been widely utilized from its inception because of the superiority in varieties of areas. The Hilbert spectrum thus obtained is able to reflect the distribution of the signal energy in a number of scales accurately. In this paper, a novel feature called ECC is proposed via feature extraction of the Hilbert energy spectrum which describes the distribution of the instantaneous energy. The experimental results conspicuously demonstrate that ECC outperforms the traditional short-term average energy. Combination of the ECC with mel frequency cepstral coefficients (MFCC) delineates the distribution of energy in the time domain and frequency domain, and the features of this group achieve a better recognition effect compared with the feature combination of the short-term average energy, pitch and MFCC. Afterwards, further improvements of ECC are developed. TECC is gained by combining ECC with the teager energy operator, and EFCC is obtained by introducing the instantaneous frequency to the energy. In the experiments, seven status of emotion are selected to be recognized and the highest recognition rate 83.57% is achieved within the classification accuracy of boredom reaching 100%. The numerical results indicate that the proposed features ECC, TECC and EFCC can improve the performance of speech emotion recognition substantially.     

Classroom action research on formative assessment in a context-based chemistry course

Context-based science courses stimulate students to reconstruct the information presented by connecting to their prior knowledge and experiences. However, students need support. Formative assessments inform both teacher and students about students’ knowledge deficiencies and misconceptions and how students can be supported. Research on formative assessments suggests a positive impact on students’ science achievement, although its success depends on how the formative assessment is implemented in class. The aim of this study was to provide insights into the effects of formative assessments on achievement during a context-based chemistry course on lactic acid. In a classroom action research setting, a pre-test/post-test control group design with switching replications was applied. Student achievement was measured in two pre-tests, two post-tests and a retention test. Participants were Grade 9 students from one secondary school in the Netherlands. Repeated-measures analysis showed a significant effect of formative assessments on students’ achievement. During the implementation of the formative assessments, intriguing discussions emerged between students, between students and teacher, and between teachers. Adding formative assessments to context-based approaches reinforces their strength to meet with the current challenges of chemistry education. Formative assessments affect students’ achievement positively and stimulate feedback between students and teacher(s).
