Computing makes it easy to reuse and remix others' creations, and this comes with a level of responsibility. Students credit artifacts that were created by others, such as pictures, music, and code. Credit could be given orally if presenting their work to the class, or in writing if sharing work on a class blog or website. Proper attribution at this stage does not require formal citation, such as in a bibliography or works cited document. For example, when creating an animation of the sun, moon, and stars using a blocks-based language, students could draw their own sun and use an image of the moon and stars from a website or a teammate. When students present the model to the class, they can orally give credit to the website or peer for the contributions.
