Design experiments in Japanese elementary science education with computer support for collaborative learning: hypothesis testing and collaborative construction

This paper reports design experiments on two Japanese elementary science lesson units in a sixth‐grade classroom supported by computer support for collaborative learning (CSCL) technology as a collaborative reflection tool. We took different approaches in the experiments depending on their instructional goals. In the unit ‘air and how things burn’, we designed the unit where groups of students engaged in building theories on ‘how a candle stops burning in a closed jar’. In the unit ‘characteristics of various solutions’, groups of students collaboratively constructed a pH scale as knowledge artefact. In both studies, the CSCL technology was implemented mainly for facilitating collaboration between groups. Results showed that: (1) students were more likely to engage in symmetric communication (i.e. between groups as well as within groups) in the second unit, and (2) they were also more idea‐centred and more frequently shared their ideas in the second unit. The results were discussed from the perspectives of the scientific practices students engaged in and task structure.     

选择适应论视野下翻译中的图式移植

翻译的过程在某种程度上可理解为“图式移植”的过程，移植内容、移植方式贯穿译者的整个创作过程。图式移植的实现是译者主动选择和适应的结果，移植成功与否与译者做出的选择和适应息息相关。     

少数民族传统体育文化资源开发利用的保障机制——以桂滇黔地区为例

由于少数民族传统体育文化保护起步晚和对其保护的公共投入不足,经济发展相对滞后、但传统体育文化资源占优的桂滇黔地区对通过开发传统体育文化具有的经济价值来弥补其保护资金不足有着更为迫切的需求。然少数民族传统体育文化资源的开发利用涉及诸多方面的利益,要实现其开发利用的可持续性,需从法律法规、资金支持、人才培养、规划评估、区域合作等方面建立起一整套有效的保障机制,使其开发利用的综合效益得到充分发挥。     

钟嵘《诗品》称王融表字初探

钟嵘《诗品》将与他稍早的南齐诗人王融列居下品,其对于王融多称表字,引起后人争议。《四库全书总目·<诗品>提要》最早提到这一问题,但给出的解释显得含混。结合齐梁易代之史实,钟嵘之所以称王融表字,既非有所私尊,亦非避齐和帝之讳,而是避梁武帝之忌讳。

亲子互动治疗研究的新取向

随着亲子互动治疗的研究和应用范围扩大,亲子互动治疗研究出现新的取向:亲子互动治疗的应用范围明显扩大,亲子互动治疗的实施方法出现变异和创新,开始关注影响治疗效果的治疗师等变量,治疗过程中患者的离开现象引起了研究者的重视等。其研究的新取向为我国心理治疗领域的深入和拓展提供了新的研究思路。     

国际背景下的我国初中化学课程的发展

从国际影响的视角看,可将我国初中化学课程在1978年到2001年间的变化划分为四个阶段。在每一个阶段,初中化学课程都受到国际的影响,在不同阶段所影响的内容与程度是不同的,当国际趋势符合国内的教育(课程)政策时,它便能较大幅度地影响化学课程,反之则弱。

论翻译能力的构成因素

本从个体翻译过程的角度分析了个体翻译能力的构成因素，其目的是为翻译教学提供必要的理论依据。个体的翻译能力主要由翻译才能、翻译语能、翻译熟能和翻译智能四个方面的能力构成。翻译才能指处理语言所表达的意义的能力；翻译语能指处理语言外在形式的能力；翻译熟能与翻译过程的自动化速度有关，而翻译智能则与理解交际意图和逻辑推理能力有关。
