Tujuan penelitian ini adalah mendeskripsikan jenis dan faktor penyebab kesalahan yang dialami siswa kelas VII dalam bentuk aljabar berdasarkan Teori Nolting. Metode digunakan deskriptif kualitatif. Subyek terdiri dari 10 diambil secara acak, kemudian 2 memenuhi 6 indikator tipe Nolting diwawancarai. Berdasarkan hasil diketahui bahwa persentase 50% mengalami misread direction errors, 20% careless 10% concept 25% application 32,5% test taking 7,5% study errors. Faktor tidak memiliki referensi lengkap, kurang memperhatikan penjelasan guru, mampu menangkap makna kata penting soal, salah memahami memperdalam materi terutama penerapan konsep operasi ke soal cerita matematika, melakukan latihan kontekstual, teliti, terburu-buru, mengatur waktu pengerjaan.
