Thiết kế tình huống dạy học theo bối cảnh: Trường hợp chủ đề “Vectơ” (Toán 10)

Tóm tắt

Context-based teaching is an instructional approach that connects mathematical knowledge with real-life situations, thereby enhancing the relevance and effectiveness of students’ learning. This study aims to propose a process for designing context-based teaching situations for the topic of Vectors in Grade 10 Mathematics and to evaluate the feasibility of their implementation in classroom practice. Based on a review of the theoretical foundations of context-based mathematics teaching and an investigation of the current teaching of vectors in upper secondary schools, a five-step design process was developed and several teaching situations were constructed within authentic contexts such as motion, navigation, force, running competitions, and compass use. The results of the pedagogical experiment indicated that students in the experimental group achieved better learning outcomes and demonstrated greater engagement in discussion, explanation, and application of vector concepts than those in the control group. These findings confirm the feasibility and effectiveness of designing and implementing context-based teaching situations in teaching the topic of vectors, thereby contributing to the development of students’ competency to apply mathematics in real-world contexts.
