To address this gap, this study analyzed the cognition degree of mathematical operation literacy of 51 pre-service high school mathematics teachers with an open-ended questionnaire self-designed. After analyzing, it could be found that: (a) The scope of cognition is not very broad, about 40% of the content is not recognized and the communication and reflection aspect is unrecognized; (b) Their cognition is not deep, their cognitive level mainly stays at level 1. Their cognition is not continuous and linear; (c) A few aspects of cognition are relatively clear, but in general, their cognition is not very clear. The content that they can clearly recognize is mainly the definition and expression of mathematical operation literacy and the aspect of knowledge and skill. Therefore, it is suggested that: (a) Experts and teachers in charge of certification work should expand mathematical operation literacy courses and pay more attention to them (b) Pre-service teachers should fully understand the related contents of mathematical operation literacy, go deep into each level, and clarify the expression of mathematical operation literacy.
