Anika's coding project worked perfectly until the demonstration. Then the screen froze on the first click, and the classroom filled with the soft tapping of impatient pencils. She wanted to close the laptop and say the file had been corrupted. Instead, she projected the code and traced the error line by line. A missing bracket had stopped everything. The class saw the mistake, but they also saw how she found it. Her project became less polished and more useful.
