Understand "Comet in Moominland"

Today, I held 2nd class of moomin seminar. At first I explained the outline of "Comet in Moominland" which was the next work to "Smalltroll and big flood". Next, the 21 students were divided into 5 groups and tackled the three tasks: the first was making questions on this work by using Monju, who was a Buddhist saint of wisdom, method, the second was categorizing the questions into two levels and the last was drawing a mind-map based on the categorized questions. It is very difficult that a beginner draw a proper mind-map because he/she is difficult to classify their idea into appropriate levels. So my three process method affords easy mind-map drawing to a beginner. By the way, my students must choice a question, explain the reason and answer the question by themselves till the next class.
