Is reciting Surat Al-Ikhlas, Al-Mu'awwidhatayn, and Ayat Al-Kursi at the beginning of a class considered an innovation (bid'ah)?

The commitment to reciting the Mu'awwidhat (Surahs Al-Falaq and An-Nas) at the beginning of a class and maintaining this practice is feared to fall under the category of bid'ah idafiyyah (added innovation), especially if it is a collective recitation in one voice. While the act itself is originally legislated, a newly invented method is added to it. Al-Shatibi defined bid'ah idafiyyah as: "Committing to specific manners and forms, such as committing to particular acts of worship at specific times for which the Shari'ah (Islamic law) did not specify such timings."

As for accustoming students to recite the Mu'awwidhat every morning with the intention of seeking refuge, there is no harm in it; as evidence for this has been reported, such as the hadith: "Say 'Qul Huwa Allahu Ahad' (Surah Al-Ikhlas) and the Mu'awwidhat when you enter the evening and when you enter the morning three times, they will suffice you against everything." And the hadith: "Whoever recites 'Ha Mim Al-Mu'min' up to 'ilayhi al-masir' (40:3) and Ayatul-Kursi when he enters the morning, he will be protected by them until he enters the evening."
