The primary purposes of study are to survey: Elementary teachers understanding of the new curricula. Their problems and needs in teaching. The learning outcomes of elementary students. The data in this study were collected through questionnaires, face-to-face interviews, and observing elementary teachers' teaching Math. The research found that some math teachers did not participate in the in-service teachers workshops designed for the understandings of the new curricula. Many teachers had a limited understanding of the instructional objectives for the new mathematics curriculum as well as their teaching materials/methods and the learning development of their students. Nevertheless the teachers surveyed in this study desired to improve their own teaching skills and professional knowledge. Most teachers thought their students learned math better than before; the skills of the students' problems-solving and oral presentation improved. However, some teachers held converse opinions; there was a big gap between actual teaching and ideals for them. The following are suggested by the study: Educational authorities should offer more opportunities for elementary math teachers to improve their teaching skills and mathematics knowledge. The conference for in-service math teachers sponsored by educational authorities should balance theory and practice. Educational authorities should publish suggested math teaching techniques for the new curriculum and distribute them to relevant teachers for reference. And should establish a world wide web station or a problem-solving to deal with elementary teachers' teaching problems.
