Vocabulary
- Programming language
- A set of rules in which symbols represent actions.
- Behavior
- Actions performed by a robot, defined by the programming language.
- Command
- Instructions used to create behaviors that are executed by the robot.
- Sequence
- The order in which commands are executed one after the other. The order of the touch button presses is the order in which the 123 Robot will perform the actions.
- Symbol
- An image or sign that represents something. The symbols on the touch buttons represent a behavior for the 123 Robot.
- Decompose
- Breaking down a complex problem into smaller parts that are more manageable and easier to understand.
- Move button
- Makes the 123 Robot drive forward 1 robot length, or 1 square on the 123 Field, when pressed.
- Left button
- Makes the 123 Robot turn in place 90 degrees to the left when pressed.
- Right button
- Makes the 123 Robot turn in place 90 degrees to the right when pressed.
- Start button
- Makes the 123 Robot start the project when pressed.
Encouraging Vocabulary Usage
General notes on encouraging vocabulary usage with young children:
- The goal is to expose students to Computer Science vocabulary, not to make them memorize terms without context. Students will be hearing and using these words in the context of their activities at school, and you can incorporate vocabulary into your conversations at home as well.
- Work vocabulary words into your daily routines, to help students use these words in context. Asking your student to follow a sequence to set the table for dinner, or about what behavior will help them follow directions the best, to help students connect these Computer Science concepts to their daily lives.
Tips for Encouraging Vocabulary Usage
- Work vocabulary terms into your conversations during the Lab and throughout the rest of the day. The more students hear these words used correctly, in the context of their activities, the better they will be able to incorporate them into their vocabulary and conversation. Try asking students to “follow the correct sequence to line up for recess," as well as what sequence they coded with their 123 Robot.
- Try some “Dynamite Decomposition!” Play a game to take an everyday task, like washing your hands, and decompose it into as many behaviors as you can, in the correct sequence. You can do this as a whole class activity, or in groups, and the “winner” has decomposed the task into the smallest behaviors possible.
