On February 27, 2023，Dong Hui, a member of m88 live casino and sports bettingm88 best betting websitethe teaching team of the "Economic Mathematics" course in the Mathematics Teaching and Research Section、Ji Sha、Xu Yongli carried out collective lesson preparation activities in Room 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 the content of old textbooks，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 m88 slot machine casinom88 slot machine casinolinear algebra were discussed。Different 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 understand the concepts and gain a deeper understanding of the role of mathematics in solving practical problems。However, during the teaching process, attention should be paid to explaining m88 online sports bettingm88 best betting websiteto students the connection 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。

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