Abstract
The question-answer centered theory is another important discovery after the
three major theories of modern education (student centered theory, subject centered theory
and culture centered theory), and it is also the divergence of educational models between
western countries and Eastern countries. Problem centered teaching is a theme of quality
education in recent years. Its core ideas mainly include: starting from problems, carrying
out innovative questions, cultivating problem awareness; taking problems as a link, running
through all links of "preparation, speaking, practice, assistance and examination" in
chemistry teaching; cultivating creative thinking and solving problems.
