Worhshop Title: Image Coding Activity
Design Team: Lana Nagy (DTL), Josue Samayoa, Firas Khatib, Ethan Rossi
Audience: MARC/MBRS students. Students will be juniors in college having already taken some basic biology courses as well as organic chemistry. Most students will have basic computer skills with a small minority having more advanced computer knowledge.
Goals
- Understand the process of how and image correlates to a set of data
- Students should understand how manipulating the values in an image file effects how the image is displayed
- Understand the implications that go with different resolutions
- Understanding of the significance of the elements contained in an image file
- Engineering and science correlate with one another
Evidence
- Students will communicate the data required to reconstruct the image
- Students will be able to predict the impact of image resolution
- Students will be able to predict the outcome of manipulated image data
- Students will understand the process of defining aspects of an image file such as scale, color, and resolution
Activity Description
- Facilitator intro of engineering process
- Starter – working in pairs have to verbally describe an image (possible)
- Present problem of image encoding
- Group exploration – groups of 4 need to devise a way to describe their image so that another group can reconstruct it with out looking at the picture
- Thinking tool – Light meter
- Continued group exploration
- “Jigsaw” image presentation
- Group discussion of image manipulations
- Open discussion of group discussion
Rationale
- Address attitudinal goal that Engineering and Science are similar
- Improving communication skills and solution planning
- Relating code to numbers – the idea that an image is made up of a set of numbers
- Allow groups to focus explanation of image
- Assessment – student from each group has to relay image to new group
Synthesis
Facilitation

Post 4-4-08 meeting thoughts:
great productive meeting everyone!
I was thinking about the pre-intro paired image activity.
Since these are going to be difficult images to describe already, would we want to use color images there so that they can understand from the very start
what a complex problem this is? Then when we break them into groups we give them the greyscale images?
Just a thought... ---Firas
