A Brief Survey of Deep Learning Approaches for Learning Analytics on MOOCs

Abstract

Massive Open Online Course (MOOC) systems have become prevalent in recent years and draw more attention, a.o., due to the coronavirus pandemic's impact. However, there is a well-known higher chance of dropout from MOOCs than from conventional off-line courses. Researchers have implemented extensive methods to explore the reasons behind learner attrition or lack of interest to apply timely interventions. The recent success of neural networks has revolutionised extensive Learning Analytics (LA) tasks. More recently, the associated deep learning techniques are increasingly deployed to address the dropout prediction problem. This survey gives a timely and succinct overview of deep learning techniques for MOOCs' learning analytics. We mainly analyse the trends of feature processing and the model design in dropout prediction, respectively. Moreover, the recent incremental improvements over existing deep learning techniques and the commonly used public data sets have been presented. Finally, the paper proposes three future research directions in the field: knowledge graphs with learning analytics, comprehensive social network analysis, composite behavioural analysis.

English Education Tutoring Teaching System Based on MOOC

“…The problems or issues are conveyed to the teacher in the form of a message, and the teacher can understand the students' learning situation. Additionally, existing problems in the teaching through the feedback of the students allow not only for targeted guidance to be provided to some students but also for effective improvement and reform in the teaching content and teaching methods [ 11 – 13 ].…”

“…CNN is a multi-layer neural network that can handle multi-dimensional data by applying local convolutional filters to extract features locally (Sun et al, 2021). For example, Qiu et al (2019) applied a two-dimensional CNN, which can automatically extract the best features from the raw clickstream data, and predicted dropout with more than 86% accuracy.…”

“…LSTM is especially suitable for learning complex patterns which require retention and memory, e.g., remembering past or previous performance of students while predicting their performance on future tasks (Marinescu-Muster et al, 2020). Convolutional Neural Networks (CNN) CNN is a multi-layer neural network that can handle multi-dimensional data by applying local convolutional filters to extract features locally (Sun et al, 2021). For example, Qiu et al (2019) applied a two-dimensional CNN, which can automatically extract the best features from the raw clickstream data, and predicted dropout with more than 86% accuracy.…”
