U1Ch1L7_Encoding and Sending Formatted Text _ASCII

Purpose: Students will invent a way to use plain ASCII text to encode other text.
Vocabulary: Abstraction & ASCII

Activity – Part A: With your partner, create a protocol for a binary language that will transmit text.
                     Separate from your partner. One partner will Code and the other will Decode. Then Switch.

The instructor will write one of the words below on a slip of paper and hand it to one of the two partners. Partner A will translate the word into binary using the protocol. Partner B will use the protocol to translate the binary back to text. The instructor will find out if their protocol worked.

• Decode: “?”    Switch.   Now Decode “?” (refer to class syllabus for words!)
• Decode the sentence with no formatting or punctuation: “?”.  Then Switch.  Decode the sentence with no formatting or punctuation: “?” (refer to class syllabus for words!)

Now edit your protocol so that it also takes Formatting into account:

• All Caps
• Bold
• Italics
• Underline
• Font Color
• Period / Question Mark / Exclamation Point

Activity – Part B:
Decode the sentence with formatting and punctuation: “?”. (refer to class syllabus for words!)
I am going to hand a new phrase to the transmitter who will decode it using the ASCII handout provided above. Pass it to your Decoder and see what they come up with. The first group that can decode it will win a prize.

Handout: There is a standard: American Standard Code for Information Interchange or ASCII

• I am going to hang a new formatted text with punctuation in the front of the room. The first group that can decode it using the ASCII code provided above will win a prize.

Log On To Code.org and go to the Internet Simulator: Go to the class website, log into your Code.org account and select “U1Ch1L7_Encoding and Sending Formatted Text _ASCII
 
Use the Internet Simulator to spell the phrases that they previously used with binary text protocols they developed.
