This research concluded that: (1) Some teachers acknowledged that the concept of radical Islam may have been spread among students because of their lack of religious knowledge; (2) The units of Islamic study in the schools is progressing well but there is no guarantee of immune from radicalism since most of the learning process is released to a third sides; (3) In the textbooks and worksheets there are various statements that may encourage students to hate other religions and other nations.

ABSTRAK:
Lembaga-lembaga pendidikan diduga tidak kebal terhadap pengaruh ideology radikal. Penelitian ini menyimpulkan bahwa: (1) Beberapa guru mengakui adanya konsep Islam radikal yang mungkin menyebar di kalangan siswa karena kurangnya pengetahuan keagamaan; (2) Unit-unit kajian Islam di sekolahsekolah berkembang baik namun tidak ada jaminan adanya kekebalan dari radikalisme karena proses belajarnya diserahkan kepada pihak ketiga; (3) Di dalam buku rujukan dan kertas kerja terdapat beberapa pernyataan yang dapat mendorong siswa untuk membenci agama atau bangsa lain. Dapat disimpulkan bahwa ada beberapa strategi deradikalisasi yang dapat diimplementasikan yaitu deradikalisasi preventif, deradikalisasi preservatif terhadap Islam moderat, dan deradikalisasi kuratif.
