说明

在本活动中，学生将使用干擦板和记号笔，用定格动画制作出移动圆点的假象。

路线

• Begin by making sure your dry-erase board is securely placed in a position where it will not move as you draw and erase. 
• 确保您的相机也是安全的，并且在拍照时不会移动。
• Decide on a direction or path your dot will follow on the dry-erase board. Depending on how complex you’d like this to be, you can create a simple storyboard that shows a beginning, middle, and ending frame for your animation.

• Select a colored marker to use to draw a dot that will give the most contrast with the color of your dry-erase board.
• Draw a dot. Take a photo. Erase the dot. Following the direction you decided on, draw the dot just next to where it was before you erased it. Take a photo. Erase the dot. Draw the dot again just next to the last dot you erased.
• 重复至少 150 次，直到您的点的短片似乎在白板周围移动。
• 提示：
  • Draw your dot on a clear direct path so that it appears to be moving in a line or arc. If the animation program you’re using has onion skinning, use that to help guide the amount of change in each frame.
    
  • This activity can be as simple or complex as you like. Students can increase the complexity by adding a second or third dot to their animation that has its own path (imagine a pinball machine with two or three balls in play at the same time). Or add a dash that acts as a paddle for the dot/ball, and you can re-create a game like Pong or Arkanoid.

过渡到活动

Before you begin this activity, provide the class with an example film you have premade, or make one together. 

退出活动

Before moving on to the next activity, each group can share what they created with the whole class.

课堂布置

Students can either work alone or in pairs at desks or tables. Having tables set up in a large space such as a library or cafeteria works best. This gives students room to set up cameras and devices and securely set up whiteboards.

支持/自适应材料/工具

• Share short, preprinted, and completed storyboards for students to animate. This could be framed as though you’ve been hired to animate this storyboard. The storyboard could also be partially complete, with a couple panels left blank for students to complete. 
• 一种 定时器/visual timer can be used to remind students to rotate roles (as applicable), save their animation, and play back their animation for continuity and quality of motion.
• Only provide high-contrast marker options.
• Provide pencil grips for students using pencils to work on their storyboard.
• If someone is using a wheelchair or other tool to support their motion, ensure there is enough space around the equipment and tape down anything that may be a trip hazard. 

课堂专业人员可能扮演的角色

• Check in with students as they create their work.
• 提议成为学生的摄影师，这样他们就可以专注于他们的点画。

远程教学的调整

Use a 2D animation program to mimic the dry-erase animation or share your screen with your dry-erase board up. Students can participate by giving you directions on the path of the dot’s movement. Students could also work on their own to create a film of their moving dots and then share their screen at the end of the activity.
