I had a high school teacher like that, except she also involved me in the research. She'd get out her college textbooks and point me to the right sections that might have relevant info, and answer context questions if I didn't understand the book. While I read she'd also search for the answer online. (Of course, I had to bring these questions to her after class. If I asked during the lecture, the answer was usually "not in the scope of this class. Moving on.")
