1) The document discusses three suggestions for making an impact at an HLTA conference: focusing on learning rather than grades, praising students for growth rather than intelligence, and previewing lessons as well as reviewing them. 2) It notes that students show greater motivation and strategic thinking when teachers focus on the learning process instead of grades.

The right type of praise emphasizes hard work rather than being "clever" or "gifted."
