Abstract
The evaluation of classroom teaching quality is closely related to the development of higher education as a scientific and effective evaluation system that can provide a solid foundation for formulating educational policies. Therefore, an evaluation model of classroom teaching quality in colleges and universities is established based on the fuzzy fault tree theory with “classroom teaching failure” as the top event to effectively evaluate the reliability of college classroom teaching and optimize the teaching strategies. In consideration of the lack of availability and dynamics of classroom teaching data, fuzzy numbers are used to describe the probability of underlying events. In addition, the top event probability of the fuzzy fault tree is calculated by the double-layer Monte Carlo method (MCM), which analyzes the classroom teaching effect based on the fuzzy fault tree reasonable. In summary, the quantitative evaluation system of classroom teaching quality based on fuzzy fault trees can evaluate classroom teaching more comprehensively and dynamically and help to improve the teaching quality of higher education.
Highlights
Changes in College Classroom TeachingThe objective and effective evaluation of teaching quality is a key factor related to the development of students, professional development of teachers, and the quality of college education and teaching and a basis for educational decision-making (Qiao et al, 2016), even related to the personal stress and anxiety of the undergraduates (Vilvens et al, 2021)
The traditional classroom teaching evaluation methods are limited by many factors, such as technology, system, and some human factors (Lee and Mccabe, 2020) in the process of their implementation that leads to objectivity and even unfairness
The Fault Tree Analysis (FTA) method is further optimized, that is, fuzzy mathematics is introduced to describe the uncertainties of occurrence probability of the bottom event that may cause college classroom teaching failure
Summary
The objective and effective evaluation of teaching quality is a key factor related to the development of students, professional development of teachers, and the quality of college education and teaching and a basis for educational decision-making (Qiao et al, 2016), even related to the personal stress and anxiety of the undergraduates (Vilvens et al, 2021). The fuzzy fault tree method is used to figure out the factors that influence the classroom teaching effect, quantitatively evaluating the college classroom teaching quality that made the analysis more reasonable and more feasible. The factors that cause classroom teaching failure mainly include teachers, students, and the environment, which are regarded as the intermediate events of the fault tree.
