Supporting learning with interactive multimedia through active integration of representations     

Daniel?BodemerEmail author  Rolf?Ploetzner  Katrin?Bruchmüller  Sonja?H?cker 《Instructional Science》2005,33(1):73-95

When learners explore dynamic and interactive visualisations they are often not able to interact with them in a systematic and goal-oriented way. Frequently, even supporting learners in processes of discovery learning does not lead to better learning outcomes. This can be due to missing pre-requisite knowledge such as the coherent mental integration of the pictorial and symbolic sources of information. In order to support learners in this process, we encouraged them to interactively and externally relate different static sources of information to each other before exploring dynamic and interactive visualisations. We evaluated the benefit of this instructional support in two experimental studies concerning the domains of statistics and mechanics. It revealed that the active integration of static representations before processing dynamic visualisations resulted in better performance and can provide a basis for a more systematic and goal-oriented experimentation behaviour during simulation-based discovery learning.in final form: 16 November 2004  相似文献   

Modeling Partial Knowledge on Multiple‐Choice Items Using Elimination Testing     

Qian Wu  Tinne De Laet  Rianne Janssen 《Journal of Educational Measurement》2019,56(2):391-414

Single‐best answers to multiple‐choice items are commonly dichotomized into correct and incorrect responses, and modeled using either a dichotomous item response theory (IRT) model or a polytomous one if differences among all response options are to be retained. The current study presents an alternative IRT‐based modeling approach to multiple‐choice items administered with the procedure of elimination testing, which asks test‐takers to eliminate all the response options they consider to be incorrect. The partial credit model is derived for the obtained responses. By extracting more information pertaining to test‐takers’ partial knowledge on the items, the proposed approach has the advantage of providing more accurate estimation of the latent ability. In addition, it may shed some light on the possible answering processes of test‐takers on the items. As an illustration, the proposed approach is applied to a classroom examination of an undergraduate course in engineering science.  相似文献   

文化全球化与道德教育   总被引：5，自引：0，他引：5  

冯建军 《高等教育研究》2007,(5)

文化全球化不是同质化,又不是西方化。当前的文化全球化应是多元文化的共处,但这又不是文化的自我封闭和文化的民族主义,而是文化间的“和而不同”。全球化时代人们对待文化,尤其是对待具有价值指向的道德文化的态度,构成了文化全球化时代道德教育的核心。  相似文献   

试论全纳课堂的教学设计     

张婧 《中国特殊教育》2005,(1):22-27

儿童的个别差异是客观存在的,传统的以智力测验为基础的智力观较为狭窄,既不利于照顾儿童个别差异的课堂教学的实现,也不利于教育普及和教育机会均等的实现。多元智能理论以其不同于传统智能理论的观点为以学习者为中心的教学设计提供了理论支持。本文试将多元智能理论与教育技术学中有关教学设计的理论相结合,将多元智能理论引入到课堂教学设计之中,探讨多元智能课堂教学设计的过程,并尝试按照该过程设计出具体实例。它面向的是全纳教育的理想课堂,因而不仅是适用于普校的课堂教学,对于那些有随班就读学生的课堂也是同样适用的。  相似文献

Handling missing data: analysis of a challenging data set using multiple imputation     

Maria Pampaka  Graeme Hutcheson  Julian Williams 《International Journal of Research & Method in Education》2016,39(1):19-37

Missing data is endemic in much educational research. However, practices such as step-wise regression common in the educational research literature have been shown to be dangerous when significant data are missing, and multiple imputation (MI) is generally recommended by statisticians. In this paper, we provide a review of these advances and their implications for educational research. We illustrate the issues with an educational, longitudinal survey in which missing data was significant, but for which we were able to collect much of these missing data through subsequent data collection. We thus compare methods, that is, step-wise regression (basically ignoring the missing data) and MI models, with the model from the actual enhanced sample. The value of MI is discussed and the risks involved in ignoring missing data are considered. Implications for research practice are discussed.  相似文献

基于梯形模糊语言变量的多属性决策方法   总被引：2，自引：0，他引：2  

梁雪春  陈森发 《东南大学学报》2008,24(4)

研究了决策者的偏好信息（属性值）为梯形模糊语言变量（TFLV）的模糊语言多属性决策问题．定义了2个梯形模糊语言变量比较的可能度公式并研究了它的一些基本性质,给出了基于可能度公式的梯形模糊语言变量多属性决策的方案排序方法．这种方法通过对决策信息进行TFLWA算子加权集结,并通过比较梯形模糊语言变量的可能度得到所有方案的排序结果．在不损失模糊语言信息的条件下,该方法计算过程简单,决策结果合理且有效．最后,通过一个实例说明了该方法的操作过程．  相似文献   

地方性高校外语专业复合型翻译人才培养模式构建的探讨     

王秀萍  王爱琴 《台州学院学报》2008,30(2):71-74

外向型经济的迅速发展,迫切需要大批复合型、应用型翻译人才,各地方性高校也纷纷开设本科翻译专业或翻译方向以适应社会发展的需要。地方性高校有许多共性,因此宏观地探讨复合型、应用型翻译人才的培养模式、设置最优化的课程体系显得十分必要,而构建以培养翻译能力为中心的课程模式是翻译人才培养模式和最优化的课程体系得以实现的途径。  相似文献
