大单元教学要立足于“学习事实具身”处理和设计——以必修上册第七单元教学为例

大单元教学立足于“学习事实具身”处理和设计,是指围绕学习事实具身处理和设计学习任务,整合学习情境、资源、内容和方法,进而组织、开展、反思和评价学习的教学处理和设计。其具体的策略和做法是教学目标要确定为立足于学习事实具身的目标实体体系;内容要选择为立足于学习事实具身的教学文本认定;活动和评价要践行成学习事实具身活动的开展和评价等。它是当前课程话语体系与实施理念下进行教学处理和设计的重要变革,是课程学习任务群学习任务真正得以实现和学科核心素养培育确实得以落地的关键所在。

The Design and Implementation of Multi-user Data Sharing Platform for Remote Monitoring System Based on Virtual Instruments

Remote data monitoring system which adopts virtual instrument usually applies data sharing, acquisition and remote transmission technology via internet. It is able to finish concurrent data acquisition and processing for multi-user and multi-task and also build a personalized virtual testing environment for more people but with fewer instruments. In this paper, we＇ 11 elaborate on the design and implementation of information sharing platform through a typical example of how to build multi-user concurrent virtual testing environment based on the virtnal software LabVIEW.
