Under the enlightenment of “Teaching and Learning of a Lesson on Lesson” written by a teacher named Zhang Ding'er who coaches in the Journal, “The candle goes out,” and Han Ji-chun and other teachers, The six-year education eleventh natural textbook “electromagnet (a)”, “electromagnet (b)” teaching design has been improved.
