其他标题：A Lesson to Let Students Appreciate Korin's "Red and White Plum Blossoms" Screen Through Discussion on the Strange Discontinuity of the Stream Between the Two Halves
其他摘要：Korin's "Red and White Plum Blossoms" screen has a strange discontinuity of the stream between the right and left pieces. The author hypothesizes that Korin intently made it so for people to imagine an invisible stream between the two halves which stand separately, and the author indicates almost all the figures in textbooks were indifferent to this discontinuity of the stream. According to the analysis of the screen with this hypothesis, the author demonstrates three problematic stages for lessons as follows : 1. How this screen ought to be folded. 2. How far apart the two pieces ought to be separated when they are set up. 3. How students imagine the line of the stream between the two halves. Two lessons were put into practice by the author, and they proved the effectiveness of the author's demonstration.
