This study tried to state the "voice" element in eighth-grade science and technology
of natural life is used as a combination of Bayesian network based learning content and
OT Theory(Ordering Theory). Especially through the construction of computer
adaptive question bank show, which is expressed in the traditional pencil and paper tests
are not misconceptions. Teachers through the process of this series of experiments to
analysis of student misconceptions and the need to reinforce some of . The results
showed that the use of constructed response questions to effectively assess the skills
students.
The results showed:
1.The reliability of the test was .82.
2.The test subjects immediately diagnosed type mistakes and learn the skills by
which the average accuracy rate to 98.05 percent.
These results show that, in this study build computerized diagnostic model
constructed response questions and the development can be individualized to achieve
the purpose for learning ability can significantly enhance teaching effectiveness.
