Heterogeneity of the educational system: an introduction to the problem

TL;DR

This paper introduces a mathematical model to analyze educational system heterogeneity based on student grades, revealing how weak institutions affect overall system structure and proposing a method to improve system homogeneity.

Contribution

It presents a novel model using interval orders and Hamming distance to quantify and analyze educational heterogeneity based on student performance data.

Findings

Weak universities contribute to system heterogeneity.

Removing weak institutions improves overall system structure.

The model effectively characterizes educational system heterogeneity.

Abstract

We analyze a heterogeneity of the educational system on the basis of one parameter: input grades of university students. We propose a mathematical model based on the construction of universities interval order. We use the Hamming distance to evaluate the heterogeneity of the educational system, and the Unified State Examination (USE) scores of Russian students to illustrate the application of the model. We show that institutions taking weak students turn the whole system of universities into a poorly structured nonhomogeneous system. In contrast, after deleting the weakest part, the remaining set of universities becomes a well-structured system
