This research was conducted to find out what influences high-level questions-generated strategies
have on the students' science learning characteristics by applying them to the 6th grade's science
class units, “Comfortable Environment” and “Combustion and Extinction." This research could obtain
the next three results. First, the high-level questions-generated strategies impressed academic
achievement and adoption of the attitudes toward science lessons. Even though scientific inquiry
skill and scientific attitudes do not show significant difference, their average points were higher after
the instruction. Especially, ‘Date Analysis’, ‘Hypothesis Foundation’, ‘Variables Control’ and ‘Generalization'
factors under the scientific inquiry skill section and ‘Life Esteem', ‘Application', ‘Criticism'
and ‘Openness' factors of the scientific attitudes section make difference. Second, 1,856 questions
requested by the treatment group during 16 lessons demonstrate that they have positive contributions
to facilitating critic and reasonable thinking. Besides, the ratio of high-level questions rather
than low-level went up as the class was taken. Third, changes of academic achievement, scientific
inquiry skill, scientific attitudes and the attitudes toward science lessons were significant in
proportion to question level.
