The paper investigates the textbook on Islamic teaching officially published for Muhammadiyah Senior Secondary Schools. It examines whether the textbook promotes gender justice or injustice. In addition, how the teachers think about the gender discourse is also explored. The study seems important to carry out by taking account of whether the trend of gender discourses which has taken place for some decades in the public is substantially accommodated in the Muhammadiyah schools’ curriculum. Moreover, the teachers’ responses to the existing gender issues as included in the textbook may be crucial to shape since they are transla-tors of the text offered. To clarify this issue, the paper uses content analysis of the textbook and analyses the result of interview with several Muhammadiyah senior secondary schools’ teachers in Yogyakarta. The result of this study shows that even if the content of the official textbook generally emphasizes gender justice, in some cases, it promotes gender injustice and stereotypes. The expla-nation of men’s social roles in the whole Muslims’ history tends to be widely explored whereas that of the possibility of women’s roles is paid less attention. On the other hand, in other parts of the textbook, there is an explanation of the The paper investigates the textbook on Islamic teaching officially published for Muhammadiyah Senior Secondary Schools.

In the sense, the elaboration of the possibility of men and women to participate in the public is theologically explained. With regard to the teachers’ responses, the writing indicates that they generally agree with the notion of the need for women and men to share and possibly contribute in the public as long as the women in particular do not deny their domestic roles.

To conclude, the textbook contains gender justice and injustice ori-entations which have been responded variously by the teachers. Kajian ini menelaah buku teks tentang ajaran Islam yang resmi diterbitkan untuk Sekolah Menengah Atas Muhammadiyah. Kajian ini menguji apakah buku teks tersebut mempromosikan keadilan atau ketidakadilan gender. Di samping itu, kajian ini mengeksplorasi bagaimana para guru berpikir mengenai wacana gen-der. Kajian ini penting untuk mempertimbangkan apakah kecenderungan wacana gender yang telah terjadi beberapa dekade ini secara substantif diakomodasi oleh kurikulum sekolah-sekolah Muhammadiyah. Lebih jauh, respon para guru terhadap persoalan-persoalan gender yang ada sebagaimana termuat dalam buku teks menjadi penting karena mereka merupaka para penerjemah dari buku teks tersebut. Untuk mencapai itu semua, kajian ini menggunakan analisis isi atas buku teks dan menelaah hasil wawancara dengan beberapa guru Sekolah Menengah Atas Muhammadiyah di Yogyakarta. Hasil kajian ini menunjukkan bahwa meskipun secara umum muatan buku teks resmi menekankan keadilan gender, dalam beberapa hal, juga mempromosikan ketidakadilan gender dan prasangka. Penjelasan mengenai peran sosial lelaki dalam keseluruhan sejarah Muslim cenderung memperoleh paparan luas, sementara peran sosial perempuan kurang memperoleh perhatian. Di sisi lain, sebagian buku teks juga menjelaskan tentang pentingnya sikap demokratis bagi Muslim dalam kerangka hubungan-hubungan sosial. Dalam hal ini, elaborasi mengenai peluang lelaki dan perempuan untuk berpartisipasi dalam ruang publik telah dijelaskan secara teologis. Dengan memperhatikan respon paraguru, kajian ini menunjukkan bahwa mereka umumnya sepakat dengan paham mengenai erlunya perempuan dan lelaki berbagi dan mungkin berkontribusi dalam ruang publik sejauh perempuan tidak menolak peran domestik mereka. Mereka agaknya mencoba menguji muatan buku teks melalui pertimbangan rasional hingga teologis. Akhrinya, buku teks bermuatan orientasi keadilan ketidakadilan gender yang telah direspon secara berbeda oleh para guru.
