he Comprehensive Boost of Teaching Quality: Physics Teachers in Need of Rich Ontic Knowledge ——Based on Analysis of 30 Teaching Cases in the Physics Classrooms

In the context of the fast development and application of science and technology, the knowledge content and teaching skills required of the middle school physics teaching are drastically on the increase. Teachers short of a strong sense of duty and a rich ontic knowledge of physics and cultural appreciation will be far from competent in doing their job of physics teaching. Active and constant learning, keeping up with times and incessant expansion of one's knowledge base have become a must for the enhancement of one's ontic knowledge and the optimization of one's knowledge structure, without which the enhancement of the physics teaching can not be expected. Numerous facts have told us: knowledge of modern science and technology is the crucial component to constitute the knowledge structure of a physics teacher; the reinforced reading and enhancement of ontic knowledge on the part of the physics teachers is the key for efficient teaching and promotion of physics teaching quality.
