Currently, the application of information technology and digitization is a prominent trend in mathematics education. Mastering computer thinking in general and algorithmic thinking in particular brings many benefits. For 11th-grade teachers and students, practicing algorithmic thinking when teaching the orthogonal projection of a point onto a plane presents many challenges. To address these challenges, teaching this content requyres the support of information technology in general and the GeoGebra software in particular. Using a theoretical research method, this paper analyzes concepts related to practicing algorithmic thinking, provides some classifications of algorithmic thinking, and outlines a teaching process for developing algorithmic thinking skills. Notably, the study presents examples demonstrating the practice of algorithmic thinking in teaching the topic of determining the orthogonal projection of a point onto a plane. The results will serve as a practical foundation for improving teaching effectiveness for teachers and the quality of learning for students regarding the topic of determining the orthogonal projection of a point onto a plane, with the support of GeoGebra software.Hiện nay, ứng dụng công nghệ thông tin và số hóa đang là những xu hướng được quan tâm trong dạy học toán.
