On February 27, 2023，Dong Hui, a member of the teaching team of the m88 com live casino register"m88 best online betting websiteEconomic Mathematics" course in the Mathematics Teaching and Research Section、Ji Sha、Xu Yongli carried out collective lesson preparation activities in 309 South Building 0。

Because this semester is using new textbooks，First of all, we conducted a collective discussion on the overall teaching content of this semester based on the new textbooks，Including comparison with old textbook content，And the content that needs to be explained, etc.。

Secondly, the teaching details of the concepts of determinants and matrices in the teaching content of the first chapter of linear algebra were discussed。m88 best online betting m88 com live casino registerwebsiteDifferent from the old textbook, the new textbook introduces matrices by explaining how to solve linear equations，The concept and properties of determinants are given on the basis of matrices。In response to this change，All three teachers believe that the teaching sequence of the new textbook can present mathematical concepts in the process of solving problems，Helping students gain a deeper understanding of the role of mathematics in solving practical problems based on their understanding of concepts。However, during the teaching process, attention should be paid to explaining to students m88 slot machine casinothe m88 best betting websiteconnection between matrices and determinants while also emphasizing the differences between them，Also note that although the concept of matrix appears in Chapter 1, the focus is on determinants，We need to explain the relevant content of determinants clearly and thoroughly。

Finally，Exchanged experiences on class discipline and student learning behavior management。
