This research was aimed to analyze the field independce and
field dependentce) in junior high school students'' problem-
solving behabiors in stoichiometry. Students in Changhua area
were chosen to participate in this program (total 145 persons);
According to the result of Messick Embedded Figures Test, six
of "field independence" type and five of "field dependentce"
type were selected to join the final research. The results of
the research:(1) in the aspect of comprehension problem,
students of field dependence type usually applied "rereading"
and "ask a question" strategies to understand the peoblem while
students of field independentce applied "reformulation" and
"ask a question" strategies; (2) in representation process,
both of these two types of students used the "manual of
implemenation exploration" and "information of applied memory"
(3) in the use of recalling of problem-soving behaviors, there
were more field dependence type students referred to it than
the other type; (4) in the problem-solving process, all of the
students in two types practiced "concept reasoning" behaver;
(5) in the aspect of commenting about solution, students in
both of these two types answered with "not sure" and "don''t
know"; (6) about problem- solving stratagem, students in field
dependence tend turn to "aim-oriented," "trial and error,"
"algorithmic," and "reasoning" stratagems, and field
independence type students mostly turned to "reasoning,"
"algorithmic/reasoning," "aim-oriented" and "original creation"
stratagems; (7) in the errors of solving problem, it was common
for field dependence type students to mistake the "coefficient
ratio as weight ratio", and most field independence type
students apt to "ignore the existing information". General
speaking, in the item of problem solving, the success rate of
field independence type students ( 63﹪) is higher than that of
field dependence type students ( 16﹪).
