: He tried the problem himself first, using the textbook's generalization tables . The Comparison : He checked the GDZ only after he finished.
: If his answer was wrong, he didn't just copy the correct one. He looked at the GDZ to find exactly where his logic failed—was it the valence? The state of matter?. The Outcome
By the time the chapter on arrived, Alex wasn't just copying; he was analyzing. He used the GDZ to verify his work on complex chemical reactions and stoichiometry .
