  1. Pengenalan Komputer / Operasi Komputer Dasar

  2. Kurikulum TIK @2013 (Dihapus)-issue “Anak TK dan SD saja sudah bisa internetan…” TIK / KKPI bisa integratif (terintegrasi) dengan mata pelajaran lain Pembelajaran sudah seharusnya berbasis TIK (alat bantu guru dalam mengajar), bukan TIK/KKPI sebagai Mata Pelajaran khusus yang harus diajarkan Jika TIK/KKPI masuk struktur kurikulum nasional maka pemerintah berkewajiban menyediakan Laboratorium Komputer untuk seluruh sekolah di Indonesia, dan pemerintah tidak sanggup untuk mengadakannya Banyak sekolah yang belum teraliri LISTRIK, jadi TIK/KKPI tidak akan bisa diajarkan juga disekolah
