Namun, berdasarkan kenyataan, ada banyak karakter Indonesia yang jauh di bawah ekspektasi standar dalam Item Pancasila, sebagai penjelasan lebih lanjut tentang nilai-nilai dalam Pancasila. Oleh karena itu, perlu untuk memperkenalkan Pancasila dan 45 poinnya dalam sistem pendidikan formal kita. Buku teks masih menjadi media pendidikan formal sekolah dasar. Dengan menilai beberapa buku yang diterbitkan oleh penerbit terkemuka dan digunakan di sekolah-sekolah, ditemukan bahwa mereka hanya memasukkan sedikit dari barang-barang itu. Penelitian ini diadakan untuk mengetahui apakah poin-poin karakter Pancasila yang perlu diketahui oleh pelajar Indonesia telah dimasukkan dalam buku teks berjudul When English Rings the Bell: Books Student and When English Rings the Bell: Books's Teacher yang secara resmi diterbitkan oleh the Educational and Kementerian Kebudayaan Indonesia dan menggunakan buku teks utama di sekolah-sekolah model sebagai implementasi dari Kurikulum 2013. Temuan menunjukkan bahwa sebagai buku teks resmi memiliki jumlah beberapa poin Pancasila yang memadai di dalamnya.
