在教育信息化的大背景下,如何将网络技术运用于教和学的活动已成为研究者关注的重要问题。基于教学内容,开发适用于特定教学对象的教学app(application,即安装在智能手机或平板电脑上的应用),可以成为教师开发和利用信息技术的方法和途径。通过介绍如何利用在线app制作平台,结合初中科学“物质的构成”一节内容,搭建适用于学生预习活动的教学app。主要介绍自制app中插入文字、图片和视频的方法。最后,分析基于自制app进行预习的效果,主要有以下几点:突破单一的预习方式、体现交互式的预习方式、体现个性化的预习方式、体现信息化目标的预习方式。
Under the background of education informatization, how to apply network technology to teaching and learning activities has become an important issue that researchers pay attention to. Based on the teaching content, developing a teaching app (application installed on a smart phone or a tablet) suitable for a specific teaching object can be a method and a channel for teachers to develop and utilize information technology. By introducing how to make use of the online app production platform and combining with the content of junior high school science “material constitution ”, a teaching app for student preview activities is set up. Introduced homemade app to insert text, images and video methods. Finally, we analyze the effects of pre-learning based on self-made app. The main points are as follows: break through a single pre-preview mode, interactive preview mode, personalized preview mode, preview mode of information target.
