初中科学数字化教学资源WISE“绘图故事”的研究

Research on"Graphing Stories"in WISE as A Digital Teaching Resource of Science for Middle School

科学课程应重视图教学,还应积极开发相关的数字化教学资源。基于网络的科学探究环境WISE提供的“绘图故事”项目,采用知识整合理论设计探究过程,促进学生主动建构新知识;创设科学故事线,激发学生在真实探究情境中学习;依据学习目标设计数字资源序列,确保技术目标与探究学习目标相一致;针对学习阻障设计数字化认知工具,破解常规探究教学的难点;借助虚拟动画搭建表达和反思的支架,帮助学生自主探究。研究发现,采用知识整合理论设计数字化教学资源,可以有效促进八年级学生对运动图的理解并提高他们的知识整合水平,增益效果超过中等,为有效开发探究式初中科学数字化教学资源提供了具体指南,也为科学课程的图教学提供了数字化教学资源的样例。

Science curriculum should pay attention to the graphical teaching,and actively develop relevant digital teaching resources.This study finds that the"Graphic Stories"project in WISE(web-based scientific exploration environment),using Knowledge Integration theory to design digital teaching resources,can effectively promote eighth grade students′understanding of motion graphs and improve their knowledge integration level,with a gain effect exceeding moderate size.The exploration process in this project is designed based on the theory of Knowledge Integration that promotes students to actively construct new knowledge.It creates scientific storylines that inspire students to learn in real-life explorative contexts.A sequence of digital resources is designed based on the learning objectives to ensure consistency between technical objectives and exploratory learning objectives.Digital cognitive tools are designed for learning obstacles to overcome the difficulties of conventional inquiry teaching.It uses virtual animation to build a framework for expression and reflection,helping students explore independently.This study provides specific guidelines for effectively developing exploratory digital teaching resources in middle school science curriculum,and also provides examples of digital teaching resources for graphical teaching in science curriculum.
