The teachers were also asked to review whole mathematics curriculum and to explain the strengths and weaknesses of the curriculum based upon their experiences during the pilot administration of the curriculum. Their responses are summarized in following Table 2. Table 2 presents that the newly developed mathematics curriculum has many strengths as well as some weaknesses. In relation to strengths mentioned by teachers, the new curriculum serves many visualized and student-centered activities. The topics to be covered are not much more detailed as it was before. In addition, the other positive aspect of the curriculum is that it enables the students to construct their own knowledge by living, doing, searching, sharing, and experiencing. These processes provide the opportunities for the students to self-express, to be self-confident and selfawareness. Also, with new curriculum the teachers adopt the roles of guide and facilitator. Being guide and facilitator promote the teacher to develop and equip themselves with necessary skills. The new curriculum encourages cooperation among groups (for example between teachers in math group and teachers in science group) in schools in order to overcome the problems and difficulties faced. All the processes emphasize the importance of participation of each student in class activities. In other words, the new curriculum emphasizes the understanding of “no students left behind”.
