Vận dụng lí thuyết giáo dục toán học gắn với thực tiễn trong dạy học Định lí Cosin (Toán 10)
Tóm tắt
Realistic Mathematics Education (RME) was developed at the Freudenthal Institute in the Netherlands in 1971 based on two perspectives: mathematics must be associated with practice and mathematics is an activity of humans. RME emphasizes the role of teaching starting from situations and problems with real contexts. This study presents a result of teaching experiments on the Cosine theorem through solving a practical problem according to RME Theory including five steps: raising a practical problem, discovering the Cosine theorem, formulating the Cosine theorem, solving Initial practical problems, and applying the Cosine theorem in practice. The experimental results show that the students actively participated in the process of discovering the Cosine theorem through solving learning tasks; Realized the close relationship between mathematics and practice, and developed independence and confidence in learning activities.
