A. Conclusions

As stated in chapter I, this study is conducted to design a set of English speaking instructional materials for mathematics teachers of the seventh grade of junior high school studying at the bilingual preparation program of Wisma Bahasa Yogyakarta. The writer started the study by formulating two problems to be answered. They were: 1 How is a set of English speaking instructional materials for mathematics teachers of the seventh grade of junior high school studying at the bilingual preparation program of Wisma Bahasa Yogyakarta designed? 2 What does the designed set of English speaking instructional materials for mathematics teachers of the seventh grade of junior high school studying at the bilingual preparation program of Wisma Bahasa Yogyakarta look like? To solve those two problems, the writer employed Educational Research and Development R D method. Actually there are ten steps on the R D cycle.
