The method of study used quasi experiment by non-equivalent control group design. The population of this study are eighth grader students of Senior High School in Tangerang City, Banten Province. Sampling technique used cluster random sampling with the numbers of students are 140 students. The instruments used in the form prior mathematical knowledge test and mathematical reflective thinking ability test. Data analysis are done by requisite test, namely data normality test (Kolmogorov-Smirnov Z Test) and homogeneity test (Levene Test). The statistic analysis of the data was conducted with one-way ANOVA, two-way ANOVA, and Scheffe Test. The results of study are as follows: (1) there is enhancement difference of mathematical reflective thinking ability of the students learning with knowledge sharing strategy and conventional learning; (2) there is enhancement difference of mathematical reflective thinking ability between students learning with knowledge sharing strategy (KSS) and conventional learning based on school level and prior mathematical knowledge (MPK) of students (higher, middle, lower); (3) The interaction between learning strategy (KSS) and prior mathematical knowledge (higher, middle, lower) influenced student’s enhancement of mathematical reflective thinking ability.

Sejarah penubuhan suatu organisasi tidak dapat dipisahkan daripada gagasan dan pemikiran pengasasnya. Orangorang yang bergabung menjadi ahli secara sedar telah bersetuju dengan dasar dan matlamat organisasi tersebut yang pada hakikatnya adalah perwujudan daripada gagasan para pengasasnya. Demikian halnya dengan Muhammadiyah, di Indonesia tidak mungkin dipisah daripada Ahmad Dahlan sebagai pengasasnya. Lebih asas lagi, kelahirannya sebagai gerakan Islam melalui sistem organisasi juga memperolehi rujukan teologi, sebagaimana tercermin dalam pemaknaan atapun tafsiran surah al-Quran Cali Imran ayat 104. Artikel ini menggunakan metodologi kualitatif bersifat deskriptif analitikal, iaitu tulisan yang berusaha menggambarkan data yang sesuai keadaannya. Dalam memformat gerakan Muhammadiyah dalam konteks kelahirannya bukan hanya semata-mata teknikal tetapi juga didasari pada rujukan keagamaan yang selama ini melekat dalam alam fikiran para ulama mengenai Kaedah “mâ lâ yatimm al-wâjib illâ bihi fa huwâ wâjib”, ertinya sekiranya suatu urusan tidak akan sempurna manakala tanpa alat, maka alat itu menjadi wajib adanya. Hal inilah yang membuat gerakan Muhammadiyah, terutama di bidang lembaga pendidikan semakin laju sejak didirikannya pada tahun 1912 hingga tahun 2010 telah berjumlah 16,942 buah.

Sejarah berdirinya suatu organisasi tidak dapat dipisahkan dari gagasan dan pikiran pendirinya Sebab orang-orang yang kemudian bergabung menjadi anggota secara sadar telah menyepakati dasar dan tujuan organisasi tersebut yang pada hakikatnya merupakan perwujudan dari gagasan para pendirinya PSII tidak mungkin dipisahkan dengan HOS Cokroaminoto NU tidak mungkin dipisahkan dengan Hasyim Asyaari Demikian juga Muhammadiyah tidak mungkin dipisahkan dari Ahmad Dahlan Dengan demikian gagasan dan pikiran yang muncul kemudian tidak mungkin dipisahkan dari pikiran dan gagasan awal (para) pendirinya, (Moh Djasman Al-Kindi; sala seorang pencetus berdirinya Ikatan Mahasiswa Muhammadiyah dan menjadi ketua umum pertama DPP IMM) Gagasan Ahmad Dahlan yang terpilih adalah bagaimana dapatnya mengamalkan ayat-ayat al-Quran Dengan demikian Muhammadiyah sebagai organisasi senantiasa diikhtiarkan untuk menjadi tempat untuk mengkaji Al-Qur`an sekaligus menjadi tempat bermusyawarah untuk mengamalkannya Oleh karenanya Muhammadiyah tidak mungkin terpisah dari tiga prinsip yakni ; Pengkajian Al-Quran, Musyawarah dan amal, yang saat ini hampir mati ; antara ada dan tiada.

Strategic intelligence is either done by the Kiyai Ahmad Dahlan nor by Kiyai- Kiyai new young home from Mecca as K.H. Mas Mansyur with K.H. Abdul Wahab Chasbullah and others. The same feeling, due to the State of the nation is still colonized by Foreign Nations so as to force those who recently return from Mecca for creative thinking by making a smart idea according to capacity which has been eaten, in order to deal with circumstances that plagued his nation. This, it is interesting to review of the origin of the appearance of movement Muhammadiyah and Nahdlatul Ulama (NU) in Indonesia, which is mainly about the history of the site of the second equation – both these organizations. Although, the Organization of Muhammadiyah and NU, is equally religious social movement organizations are sourced from the result of thoughts and musings by Indonesia students who learn from Mecca at the time. Views can be seen from: the history of the movement, thought and influence of the marriage, the teacher and the taught, the granting of a degree as a national hero, the real work of the forum and dialogue to exchange thoughts, and his education as a charitable effort movement
