Title:
Student-Centered and
Inquiry-based Teaching on Real Case |
Author:

Abstract |
The Rule of total probability is an important formula in
the probability theory and mathematical statistics,
which provides an effective way to calculate complex
probability problems in practical application, and often
simplifies a complex probability calculation problem.
However, in teaching, the application of the rule of
total probability is a difficult point, because it is
always difficult for students to master the analysis of
complex problems, and they cannot divide the sample
space well and find a suitable complete set of events,
which makes it difficult to solve specific complex
probability problems. This paper discusses a teaching
design and executing process of
the rule of total probability in probability and
statistics course. This design fully demonstrates the
student-centered principle. By introducing some
interesting real cases the teacher proposes some
questions, and then the students study the rule of total
probability in a inquiry mode from the elementary to the
profound. And to extend it which make use of the
probability density function, and analyzing its
extensive applications in insurance. This case-based
inquiry teaching method, student-centered and
case-driven, can fully mobilize students' learning
interest and initiative, cultivate students' spirit of
independent thinking and teamwork, and improve students'
comprehensive application ability.
