To propose individual variation among science gifted high school students based on the understanding
of the difference in process of problem discovering, data has been collected through interviews and
observations for two years from 20 students currently attending science high school. 4 types of individual
variations has been derived from collected data analyzed through questioning and comparing. 4 individual
types in process of problem discovering are passive type, valuable problem discovering type, normal
problem discovering type, and chaotic problem discovering type, each type distinguished by support from
expert group, and individual specialty and conversant thought. According to support from expert group,
and individual specialty and conversant thought, participants’ performance in the research were compared
and proposed through open coding of interviews, thus followed analysis on mechanism of the way
students’ problems are structured. Support from expert group, and individual specialty and conversant
thought that were shown to be important in the process of problem discovery were discussed in the
context of problem discovering education.
