Summary

The research aims to provide a new approach for teaching assessment calibration and educational equity in intelligent education. Experimental results indicate that the proposed model significantly outperforms comparative models, effectively addressing issues of poor multi-source data integration and fairness bias in existing calibration methods.

Abstract

Current teaching assessment calibration methods face challenges such as low integration efficiency when processing multi-source heterogeneous assessment data, insufficient adaptability across different disciplines and teaching scenarios, and biases in results with weak fairness guarantees. The research aims to construct an interpretable, transferable, and scalable fairness-correction framework for deep modeling and dynamic correction of teaching assessment data. These issues make it difficult to meet the core requirement of balanced teaching in intelligent education. This study proposes a fairness-oriented educational network algorithm that integrates a generative adversarial network and a gradient boosting decision tree. The algorithm constructs a fairness calibration mechanism and combines a bidirectional encoder representation model with a graph attention network to optimize feature extraction and dynamic adaptability, improving multi-source data processing efficiency and fairness calibration accuracy. This approach achieves precise calibration and fairness assurance in teaching assessments. In the indicator test, the model achieved an accuracy of 98.76% in clustering evaluation features, 98.05% in fairness correction, and 0.968 in cross-scenario correction consistency in the validation set. In the loss value testing task, the total loss of the model decreased from 0.1237 to 0.1018 during the teaching evaluation correction task in the validation set. In the indicator test, the model achieved an accuracy of 98.76% in clustering evaluation features, 98.05% in fairness correction, and 0.968 in cross-scenario correction consistency in the validation set. Experimental results indicate that the proposed model significantly outperforms comparative models, effectively addressing issues of poor multi-source data integration and fairness bias in existing calibration methods. Furthermore, it provides innovative algorithmic frameworks for technology developers and reliable technical tools for educational administrators to promote teaching equity. The research contributions lie in: (i) integrating three core modules, including multi-source data preprocessing, dynamic fairness index verification, and explainability visualization; and (ii) proposing a fairness correction paradigm based on the collaborative optimization of generative adversarial networks and gradient boosting trees, which breaks through the limitations of traditional single-model correction and enables decoupled learning of deviation modeling and correction decision-making.

Introduction

Teaching evaluation and calibration form the core of ensuring teaching quality in intelligent education. Through dynamic analysis, error correction, and result calibration, they provide a basis for instructional improvement and personalized learning. Their accuracy and fairness directly affect whether intelligent education can break through technological biases and provide balanced educational support1,2. However, existing methods have several shortcomings: they rely on a single data source, ignore the actual situation, and lead to data bias and correction bias. Lack of a dynamic fairness adaptation mechanism ....

Protocol

FairEduNet algorithm design and optimization
The study combines GAN and GBDT to construct the FairEduNet algorithm, achieving the dual goals of fairness correction and accuracy correction, rather than the trade-off of one-way optimization. FairEduNet adopts a dual-channel collaborative architecture: the GBDT backbone channel is responsible for structured error modeling and precise correction, while the GAN auxiliary channel focuses on decoupling sensitive attributes and dynamically adjusting fairness. The FairEduNet algorithm architecture, combining GAN and GBDT is shown in Figure 1.

Results

BFEN algorithm performance analysis
The indicators evaluated in the experiments included the following:

Evaluation correction accuracy (ECA) denotes the proportion of deviation items correctly identified and rectified by the model within the teaching assessment results, thereby reflecting the overall effectiveness of the correction mechanism. Higher values indicate superior correction accuracy.

Fairness deviation rate (FDR) measures the magnitud.......

Discussion

The BFEN algorithm proposed in this study demonstrated superior performance in comparative experiments. From the perspectives of ECA and FDR, it significantly outperformed PRF, EAB, and DBLR algorithms. When calibrating 421 assessment records, BFEN increased ECA to 98.75% and maintained stability, while FDR decreased to 2.87%. This performance resulted from the integration of BERT-RL for feature optimization and dynamic adaptation. BERT precisely extracted deep semantic bias information from unstructured assessment texts.......
