The purpose of this study is to investigate cognitive
mechanisms of constructing process of students'''' scientific
attitude about suspended judgment. Through a rationale of
cognitive photospectum analysis offered by Dr. Shu. To joint
task interview and opened test as a methodology, advanced to
explore deep structure of students costruct scientific attitude
about suspended judgment,and join latent classes analysis of
ploychotomous scale model of IRT. and supply a more delicate
basis of interpretation. research instrument include a
scientific attitude scale and a opened test. Total 706 samples
include Taipei and Pintung area elementary school 5 and 6 grade
student, and 20 students are chosen as interview sample. The
significant findings of the study are the students of heuristic
and systematic thinking patterns have suspended judgment
attitude, whose latent classes analysis are both belong to the
3th category. But the students who judge for lack of evidence
intuitively have no suspended judgment atttitude, and whose
latent classes analysis belong to 2nd category. The pattern of
semantic confusing students can not construct scientific
attitude about suspended judgment,whose latent classes analysis
belong to 1st category. The results are consistency with
constructivism viewpoints .The student is a cognitive organism
who can construct meaning from information outside
automatically. The processes of constructing suspended judgment
from outside information include attention, perception,
thinking strategy, belief, and self-persuasion, also are those
processes interaction with mass of information in long-term
memory.
