	abstract = {<p>Technology is recognized for its potential to implement exploration tasks. The ease and speed with which it becomes possible to observe many cases of a situation, allows the development of conjectures and brings conviction about their veracity. Mathematical proof, assumed as the essence of Mathematics, tends to appear to the students as something dispensable. Based on KTMT {\textendash} Knowledge for Teaching Mathematics with Technology model, this study intends to understand the impact of the teachers{\textquoteright} knowledge on mathematical proof in a context of technology integration. The study adopts a qualitative and interpretative methodology, based on case study, analyzing the practice of one teacher. The conclusions emphasize the relevance of the teacher{\textquoteright}s MTK {\textendash} Mathematics and Technology Knowledge, and TLTK {\textendash} Teaching and Learning and Technology Knowledge. The teacher{\textquoteright}s MTK guides her decisions, leading her to focus on helping students understand the meaning of conjecture and proof, valuing, at the same time, the relevance of algebraic manipulations. However, the teacher{\textquoteright}s TLTK guides her practice, where the knowledge about the students is determinant. The study provides evidence about the difficulty of articulating proof and technology, but it also clarifies the relevance of this articulation and of how the teacher{\textquoteright}s KTMT can impact the teacher{\textquoteright}s decisions.</p>
