数学课堂中的“过度与缺乏”

实施新课改以来,课堂教学形式变得多样,课堂气氛变得活跃,师生关系变得和谐而融洽。然而,听课中,我们总感觉到数学课堂教学存在着一些过度与缺乏的现象,这些问题值得我们教师深入分析与探讨。一、开发过度——缺乏有效利用     

人就这么一辈子

"人就这么一辈子"——这七个字,说来容易,听来简单,想起来却很深沉。它能使人在软弱时变得勇敢,骄傲时变得谦虚,颓废时变得积极,痛苦时变得欢愉,对任何事拿得起也放得下。

向学习最深处漫溯 ——特级教师张齐华"长方体和正方体的表面积"教学片段赏析

笔者有幸聆听了特级教师张齐华的一节社会化学习课——长方体和正方体的表面积.在课前,学生预习课本,认真完成学习单;在课堂上,学生经历组内共学、质疑深化、评价反思等过程,让错误的想法变得正确,让模糊的思路变得清晰,让肤浅的认知变得深刻,让零散的知识变得系统.

The effects of varying the interreinforcement interval on appetitive contextual conditioning

Appetitive contextual conditioning in rats and ringdoves was investigated in six experiments. In Experiment 1, differential contextual training produced greater anticipatory activity in rats in the presence of a context paired with food than it did in rats in the presence of a different context in which food was never presented. Furthermore, the rats showed a preference for the context associated with food when they were given a simultaneous choice test between contexts. In Experiment 2, rats were more active in and preferred a context associated with a variable-time 30-sec (VT30) schedule as opposed to a VT180 schedule. Experiment 3 was a between-subjects replication of the previous experiment. As expected, rats exhibited significantly more anticipatory activity in a context in which food had been presented on a VT30 schedule than they did in a context in which food had been presented on a VT180 schedule. Experiment 4 showed that anticipatory activity was a reflection of context-US associations in ringdoves, and in Experiments 5 and 6, ringdoves also exhibited an inverse relationship between the. amount of anticipatory activity and the length of the interreinforcement interval (IRI). These results reveal a relation between ERI and contextual conditioning opposite from that obtained in studies of aversive conditioning.     

陈毅元帅战争诗词简论

陈毅元帅的战争诗词是20世纪生动形象的革命战争史，又是壮美深沉的民族精英心灵史：在审美上既重风骨，又富意境；在形式上古近体并重，且创作颇丰。陈毅其人品性高洁，风骨凛然，其诗亦然，是20世纪传统诗词当之无愧的大家。     

观众:作为电影叙事体中的不同角色

电影作为一种具有诱导性与强制性的叙事本,实质上左右了观众对影片意义的理解方式,同时为影片的全部意义提供一个潜在的认知结构。在这个结构中,对观众接受、体验方式的角色定位是电影制作极为重要的环节。电影观众便成为一个由电影的制作、观看与观看情境共同建构的电影叙事体系中的角色,一个我们可以潜入其中“窥视”影片内容的“假想替身”。不论是作为“窥视”、“先知”还是“认同”,观众都已经成为电影叙事本中的一部分,观众都被建构为叙事的主体并与影片的作共同“生产”影片的意义。     

The Western Primary School 'Quiet Room' Project

There has been a great deal of interest recently in the development of more 'nurturing' environments in mainstream primary schools. This interest has been reflected in a series of articles published in the pages of this journal. In this paper, Angus King, headteacher of Western Primary School, a performance management consultant, a threshold assessor and a teacher trainer, with Zara Chantler, Key Stage 1 leader and SENCo at Western, describe the Western 'Quiet Room' project, set up in 1999 as a response to the needs of pupils experiencing social, emotional and behavioural problems. The Quiet Room was designed to provide a nurturing environment in a dedicated space away from the classroom. In this way, argue King and Chantler, a child's emotional needs can be explored, on a one–to–one basis where appropriate, in a safe and supportive setting. The results to date are positive and there is real potential for the scheme to be extended.     

The impact of curriculum change on health sciences first year students’ approaches to learning

This study aimed to use a learning inventory (the Approaches and Study Skills Inventory for Students, ASSIST) to measure the impact of a curriculum change on students’ approaches to learning in two large courses in a health sciences first year programme. The two new Human Body Systems (HUBS) courses were designed to encourage students to take a deep approach to learning. ASSIST was completed by 599 students enrolled in a biology class in 2006 that was part of the old curriculum, and by 705 students at the beginning and end of the new HUBS courses in 2007. Changes in students’ approaches to learning over time were examined. The ASSIST scores for both HUBS courses reflected the dominance of a surface approach, followed by a strategic and then a deep approach. However, by the end of the year, students were taking a deep and strategic approach to their studies to a greater extent, and a surface approach to a lesser extent. Moreover, students enrolled in the new course adopted a deep approach to their studies to a significantly greater degree than those studying the old curriculum. Despite the predominance of a surface approach, the results suggest that it is possible to bring about small but significant positive changes in students’ learning behaviour in a very large class through curriculum change. The proportion of students preferring a surface approach, and results showing that high performance on the final exam was significantly correlated with a surface approach, probably reflected contextual factors, including assessment, and is the focus of ongoing curriculum development.     

诠释学视野下的比较诗学

诠释学作为一门指导文本理解和解释的学科，在以前类似于修辞学、语法学、逻辑学，从属于语文学。到了20世纪，诠释学由一种理解和解释的方法论发展成为一种哲学理论。诠释学的哲学转向与世界意义的多元化转向并行。随着古典诠释学向现代哲学诠释学的转换，诠释学不再仅是对经典文本的诠释而具有多元化的意义，从而为自己找到广阔的诠释空间，因此在诠释学的视野下比较诗学也具有更加开放的被诠释可能。以诠释学为背景，进一步探讨比较诗学在学理意义上的可能性和可行性，便会发现：比较诗学之“比较”不是工具论意义上的一种手段而是存在论意义上的一种思维方式，从而为比较诗学学科研究提供一个新的视角。     

《金瓶梅》书成麻城

《金瓶梅》是明代第一奇书,然而,对其作者至今众说纷纭。而“金学”界热疑的作者大都寓居过麻城,且与《金瓶梅》最早收藏者刘承禧有着密切的关系。《金瓶梅》里大量麻城方言的采用,体现出鲜明的地方特色,进一步说明作者是以麻城市井生活为模本进行艺术创作的。     

杰姆逊不是后现代主义者--略论杰姆逊的基本学术立场

杰姆逊是当代美国名的马克思主义理论家、艺理论和美学家,在国际上和中国都有较大影响。长期以来,中国学术界不少人都把杰姆逊看成后现代主义的布道。本不同意这个看法,通过对杰姆逊在上世纪80年代、90年代初、21世纪初三个时期的代表性论全面分析,得出杰姆逊从来不是一个“张扬”后现代主义理论的后现代主义“布道”,而是始终对后现代主义抱有清醒、冷静、客观的批判态度的西方马克思主义的结论。     

“破”与“立”的抉择——从后殖民视角看《北迁季节》中的身份寻求

《北迁季节》被视为当代阿拉伯文学作品的"一朵奇葩",萨利赫向读者展示了一幅充满时空变幻的迁徙之图,文中的人物身份也呈现了有"破"有"立"的动态特点。该篇试图分析小说中人物所体现的三种类型的身份寻求:抵制性的"立",模仿性的由"破"到"立",以及策略性的由"立"到"破"。文化身份不是固定封闭的,而是一个历史的动态的过程,正是"破"和"立"之间的互动式协商才为夹缝中的人物创造了"间质空间"的身份意义。
