【IT168 资讯】为什么我的课堂需要一台鼎易数影仪?

▲

　　数影仪A document camera is one of the easiest and quickest ways to integrate technology into your classroom.数影仪是将科技融入你的课堂最简单，最快捷的方法之一。这台设备简单易用。 A classroom document camera can be connected to a DLP/LCD projector through a computer or connected directly to a DLP/ LCD projector.数影仪可以通过电脑连接到投影机，或直接连接到投影机，可将拍摄的内容投射到白板上。 This one piece of classroom technology can be used to actively engage students in the learning process.数影仪能让学生在学习过程中积极参与。 Visual learners will benefit from the use of a classroom document camera by seeing small items, text, demonstrations in a much bigger way.学生能通过数影仪的放大效应看到放大了的小物件、文字和示意图。 Hands-on learners can also benefit from the use of a document camera by allowing them to be the ones placing objects or items under the document camera and explaining what they are showing.学生还能在数影仪下边演示文件或物件边讲解自己操作的原理和思路。 Another benefit of using a document camera is the decrease in copying expense.使用数影仪的另一个好处是减少复制纸张费用。 Schools are always looking at ways to maximize the financial resources that are available.学校一直在寻找如何最大限度地节省有限的财政资源。 A classroom document camera can drastically reduce the amount of copying a teacher has to do.数影仪可以大大减少老师复印课堂所需资料的数量。 Instead of copying 30 quizzes for a class, place 1 copy of the quiz under a document camera and either have students answer the questions on a sheet of paper or use clickers such as the Classroom Performance System (CPS) to have students answer the quiz questions.相反的复制为一类，1复制的文件摄像机下的测验30测验和学生回答问题，如课堂上的表现系统(CPS)的纸张或使用表决器表有学生回答问答题。 例如，在一个30个学生的课堂，老师不必给每个学生发一份试卷，而只需将一份试卷放在数影仪下面就能考核学生，并通过一份答题表格让学生填写答案即可。 这样一来就节约了30份试卷的复印纸张费用。

　　Preschool - Primary Grades Classroom Document Camera Ideas学前教育 - 小学低年级课堂数影仪应用思路

　　· Show and Tell展示和说明

　　· Science Experiments科学实验

　　· Zoom in on small items to see the details小件物品放大看到细节

　　· "Big Books" - Big books are expensive.越大的书就越贵。你可以将任何一本书放在数影仪下，将成一本“巨大”的书。You can turn any book into a big book by placing it under the document camera

　　· Math manipulatives数学演算

　　· 数影仪Place a timer under the document camera to help with time management.下放置一个计时器，以帮助管理时间。

　　· Picture schedule.展示操作步骤。 Place a picture schedule under the document camera. 将一张画和写了操作步骤的纸放在数影仪下。当某个活动的步骤完成了，就能通过数影仪指出它的时间过渡到了下一个步骤。例如， 老师可以指点"We just finished centers (show picture of "centers" on the schedule), now it's time for math (show schedule picture that represents "math") “我们刚刚完成了语文(显示的图片上了步骤”语文“)，现在我们到了数学课时间(表示”数学“的放映时间，图片)

　　· Demonstrating letter formation展示信件的内容

　　· ABC tiles - let students come up and rearrange the tiles to create words拼音和拼字- 让学生上来，并重新排列卡片创造音和字

　　· 展示盒说明Maps地图

　　· Worksheets - students can view you filling out the information instead of just listening工作表 - 学生可以查看您填写的信息，而不是只是听

　　· Save images for later use.保存供以后使用的影像。 A classroom document camera connected to a computer can act as a scanner.数影仪连接到电脑上，可以作为一台扫描仪。 Teachers can place items under the document camera and use them in class that day and "save" the image for future use.教师可以当天课堂制作的文档将放在数影仪下拍摄并保存下来，以供将来使用。

　　· Save an image of what you did in class on the document camera to place on classroom websites.保存学生做的项目内容并放到课堂网站上。 Parents can "see" what their children are learning throughout the day.家长可以“看到”自己的孩子在整个一天的学习情况。

　　· Saved images can also be incorporated into PowerPoint Presentations and Windows Movie Maker to use in activities such as end of year programs, classroom review and back to school nights.保存的图像可以用作制作演示文稿，比如今年的计划，课堂教学检查等。
