- Behavior
- Actions performed by a robot, defined by the programming language.
- Programming language
- A set of rules in which symbols represent actions.
- Symbol
- An image or sign that represents something. The symbols on the Coder cards represent a behavior for the 123 Robot.
- Command
- Instructions used to create behaviors that are executed by the robot.
- Decompose
- Breaking down a complex problem into smaller parts that are more manageable and easier to understand.
Encouraging Vocabulary Usage
General notes on encouraging vocabulary usage with young children:
- The goal is to introduce Computer Science (CS) vocabulary to young children as they explore computer science ideas with concrete objects, not to make them memorize vocabulary.
- Teach Computer Science vocabulary as naturally as you would introduce the names of different foods, animals, or toys.
- The more children hear Computer Science and Spatial Language words used with activities, the more they will begin to use them correctly. Reinforce vocabulary with everyday things. Whether setting the table, lining up for recess, displaying collections on the science table, or cleaning up the classroom, there will be opportunities to reinforce Computer Science and Spatial Language words to your students.
Tips for Encouraging Vocabulary Usage
- 2 Trues and a False:
- Facilitate a classroom discussion while playing the game 2 Trues and a False. Select one vocabulary word and write 3 statements about that word. One of the statements should be incorrect. Students should work as a class to figure out which statement is false.
- Act it Out:
- Engage students in a game of “Act it Out”! Write the vocabulary words on slips of paper and put them in a hat. Select one vocabulary word at a time to act out. See if students can make the connection and identify the vocabulary word.
- Example: Sequence
- Stand up
- Grab your pencil
- Go to the pencil sharpener
- Sharpen pencil
- Example: Sequence
- Engage students in a game of “Act it Out”! Write the vocabulary words on slips of paper and put them in a hat. Select one vocabulary word at a time to act out. See if students can make the connection and identify the vocabulary word.
- Who did it? Challenge!
- Create a class list of all vocabulary words. Have the students share how they have used or done something outside of the classroom that relates to a specific vocabulary word from the unit. Share with students throughout the unit to build the connection from what they are learning in the classroom to outside in the real world.
