语文课堂教学任务的反思与重构——西部地区中学语文课堂教学低效现象研究

课堂教学任务是为达到课堂教学目标对课堂教学活动内容所做的系统性规定与要求。长期以来语文课堂教学存在的"任务错位"现象,是导致语文课堂教学效率低下的主要原因。要改变这种状况,就要科学认识语文课堂教学任务的构成要素及其关系,重构语文课堂教学任务要素系统。语文课堂教学任务要素包括境、情、知、思、读、写、听、说、悟。这九种任务要素又可以分为三个层次。其中"境、情、知、思"是基础层任务要素,"读、写、听、说"是操作层任务要素,"悟"是发展层任务要素。     

Anatomy of a flipped classroom

A well-designed flipped course requires a significant amount of planning and preparation, but has great benefit to both students and instructor. Using Bloom’s Taxonomy as a guide, one can design effective online and in-class components that maximize benefits to students. A flipped classroom allows students more time to interact with peers and their teacher, and collaborate with teams. This paper will describe how one tourism educator flipped an advanced marketing course, as well as the technology tools used in content creation.     

Assessing greenhouse gas emissions from electric vehicle operation in Australia using temporal vehicle charging and electricity emission characteristics

ABSTRACT

Significant interest exists in the potential for electric vehicles (EVs) to be a source of greenhouse gas (GHG) abatement. In order to establish the extent to which EVs will deliver abatement, however, a realistic understanding of the electricity and transport sector GHG emissions impacts arising from different approaches to integrating EVs into the power system is required. A key issue in this regard is the extent to which GHG emissions are a function of where and when EV charging will be enabled (or disabled) by the provision of recharging infrastructure and implementation of charging management strategies by the electricity industry. This article presents an investigation of the GHG emissions arising from electricity and gasoline consumption by plug-in hybrid EVs under a range of standard EV-power system integration scenarios. An assessment framework is presented, and GHG emissions from EV use are assessed for the New South Wales (NSW) and South Australian (SA) pools of the Australian National Electricity Market (NEM) using retrospective electricity system generation data for 2011. Results highlight that there is a range of possible outcomes depending on the integration scenario and emissions accounting approach used. This range illustrates value of a temporally explicit assessment approach in capturing the temporal alignment of electricity sector emission intensity and EV charging. Results also show the importance of a clean electricity generation mix in order for EVs to provide a GHG abatement benefit beyond what would be achieved by a hybrid (but non-plug-in) vehicle. The extent to which overnight charging in NSW is observed to produce higher emissions relative to unmanaged charging also illustrates a possible trade-off between GHG emissions and benefits for electricity industry from EV charging at times of low demand.     

Real-time co-creation and nowness service: lessons from tourism and hospitality

Brands take advantage of technology, social media and constant connectivity to foster organic consumer engagement and interactions towards co-creating personalised customer service. Real-time service offers dynamic engagement with connected consumers. Brands in tourism and hospitality use technology to dynamically enhance consumer experience through co-creation. The integration of real-time consumer intelligence, dynamic big data mining, artificial intelligence, and contextualisation can transform service co-creation by mobilising recourses in the ecosystem. Nowness service emerges by dynamically engaging consumers in experience cocreation in real time. It has five interconnected characteristics that revolutionise the tourism and hospitality, namely: real-time, co-creation, data-driven, consumer-centric and experience co-creation.

输变电设备智能状态监测系统

输变电设备状态监测系统是建设坚强智能电网的核心任务之一,与电网安全可靠运行联系紧密。文章首先介绍了构建输变电设备状态监测系统的必要性,从系统框架设计入手,以生产管理信息系统（PMS）为平台,建立应用于总部、网省和地市三级的统一输变电设备状态监测系统。接着,将系统整体结构细化为三层：传感器、状态监测装置和状态监测后台,并对各层运一进行了论述,同时对系统接口进行了设计。最后,介绍了系统诊断的三种主要算法：专家系统、支持向量机、人工神经网络,目的是预测出电气设备可能发生的故障,避免事故的发生。     

PROMOTING INNOVATION IN THE ELECTRICITY INDUSTRY

Smart metering can bring significant benefits to electricity markets by allowing customers to reduce demand or increase supply when generation capacity is temporarily scarce. To reap the full efficiency and environmental benefits of this technology, regulators must allow price volatility and free entry into the market. The efficiency gains are enormous as both demand and supply will be affected by both temporary and longer‐lasting price changes. Experiments have shown the value of this approach.     

浅析新课程背景下的生活化课堂教学
