A Hybrid Framework of Deep Learning Techniques to Predict Online Performance of Learners during COVID-19 Pandemic
Abstract
:1. Introduction
- Previous studies have made models specifically designed for learner prediction relevant to only a single course, which made the model too specific.
- Recent studies that include the models for learner prediction under individual course is not an efficient strategy because it requires allocating resources to each model individually, which is an overburden. Therefore, a more generic model is needed.
- Recent studies have encountered the major limitation of lacking the number of responses used as a dataset for training the model, raising the issue of scalability in these developed models.
- The efficiency of current approaches is hindered by several challenges, such as data imbalance, misclassification, and insufficient feature set of factors considered while assessing student performance.
- The current study has proposed a framework that helps to predict the performance of learners for multiple courses. This helps prevent the creation of separate models that predict performance under a single course. In short, this study has proposed a framework that is generic enough to make sound and valid predictions considering multiple factors in view.
- To develop a reliable and effective learner outcome prediction model, a deep learning hybrid model has been presented. Combining deep learning classifiers (such as 1D-CNN and LSTM) produces a robust model that can more accurately predict learner performance outcomes based on student performance in online learning during the COVID-19 term.
- After the collection of online responses through a survey from all higher education students, their performance has been analyzed, and it has enabled to make the use of this available information to develop an adaptable model that considers a sufficient number of data points that could have an impact on student performance in any way.
- This research utilized the SMOTE method for data resampling and the Median Filtering approach for data imputation. Layers of CNN have automatically performed feature extraction and attribute selection to determine which features most significantly affect the result of predictions made about learners.
- The hybrid deep learning model utilized in this research has improved accuracy in visualizing the presence of experts in the field of advanced study and has helped to attain precision education by assisting weak students.

- Putting deep learning architecture into action for the period after COVID-19.
- Researchers could explore feature reduction techniques or alternative models that balance predictive performance and computational efficiency to mitigate computational challenges, such as simpler RNN variants or attention-based models.
- Increasing the size of the dataset and looking into data augmentation techniques can help prevent overfitting and lead to a more generalized model.
- The proposed framework could be an example for other developing nations facing similar difficulties due to the COVID-19 pandemic.
- Deploying pre-tuned models through transfer learning to improve a model’s performance even further.
- Exploring alternative deep learning architectures like recurrent neural nets (RNNs), GRU, or transformers to enhance efficiency and gather multifaceted student performance data.
- A combination of synchronous and asynchronous learning opportunities across various subject areas should be a focus of future development.
