Middle school students` conceptual changes on physics, chemistry, biology and earth science concepts which were intentionally selected by researchers had been investigated through traditional teaching and learning by paper and pencil tests and P.O.E. The weak points had been studied by individual interviews about the problems of traditional science classroom teaching after students` testing and learning about science concepts. As results, students` conceptual changes could be hardly found through traditional teaching and learning except several concepts in biology. The weak points of traditional science classroom teaching and learning were as follows: 1) Teachers teach science as finding answers. 2) The conventional science test is not performed to find students` concepts out but to recall simple knowledge or calculus. 3) Students hesitate to ask teacher questions in science class because of their colleagues` or teachers` blame. These mean that science teachers need specially designed teaching methods on the students` concepts and reseachers had to study about science classroom socialogy, what happened in science classrooms.
