The purpose of this study was to analyze writing activities of 1st grade middle school English textbooks based on the achievement standards of the 2009 revised National Curriculum and provide suggestions for improvements of textbooks. In this study, seven textbooks out of twelve were selected and their writing activities were analyzed as to whether they stick to the guidelines of the 2009 revised National Curriculum. For this purpose, specific focuses of the current study were 1) to look into writing activities based on achievement standards stipulated in the 2009 revised National Curriculum, and 2) to investigate the ratio of integrated writing activities to separate writing activities ones. The results of the analysis revealed that most of the writing activities seemed suitable based on learners’ real-life situations for achievements standards; however, the types of writing activities were rather simple, mainly focusing on given words. Next, there were not only separate writing activities but also a variety of integrated activities such as listening-writing, speaking-writing, and reading-writing activities. At the end of the paper, a few suggestions were provided to improve the qualities of writing activities in the textbooks.
