According to the experimental design, experiments one and four involve students' hands-on programming, therefore it is necessary to4Complete the class time. Students can conduct experiments according to the experimental guidance tutorial and complete the experimental report as required. Experimental thinking questions are used to deepen students' understanding of the experiments they are conducting, and can also serve as a reference for laboratory teachers when giving experimental exam questions.

The experimental teaching section generally requires14After completing the class hours, along with the explanation of the preceding knowledge and the time for the experimental exam, it will probably take18Complete within the time frame around class hours. If a laboratory class is2During class hours, it is necessary9Around the time of the next class.
