Educational data mining (EDM) is an up-coming interdisciplinary research field, in which data mining (DM) techniques applying in educational data. Its objective is to better understand how students gain knowledge and recognize the settings in which they learn to improve educational outcomes. Educational systems can store a huge amount of data that coming from multiple sources in different formats. Each particular educational problem requires different types of the mining techniques because traditional DM techniques cannot be applied directly to these types of data and problems. There are many general data mining tools are available but these are not designed for deal with educational data and an educator cannot use these tools without knowledge of data mining concepts. To overcome from this problem many authors provided educational data mining tools with different data mining techniques for different purposes. This paper surveys the EDM Tools from 2001 to 2016 and presents the consolidated list of tools in one place to help the EDM researchers. Then categorizes the tools based on data mining methods and explains the usage of EDM Tools.

There are two approaches for web video mining using traditional image processing (signal processing) and metadata based approach. In this paper, we focus on the education data mining and precisely MOOCs which constitute a new modality of e-learning and clustering techniques. We present a methodology that can be used for mining Moocs videos using metadata as leading contribution for knowledge discovery.

Chapter 26 - Relevance of data mining techniques in real life

University students face challenges with time management skills and stress that affects academic performance.Furthermore, the lack of awareness and access to resources for healthy sleep patterns is also a major challenge for university students to achieve academic success and overall well-being.The purpose of this study is to perform educational big data mining that analyzes the relationship between sleep management, time management, food management,, mental / mental management and academic performance and to explore the role of friends in mediation through the large ICPSR dataset (originally >90,000 sample size, 42 datasets).The study selected, merged, cleansed, and transformed the most relevant ICPSR datasets 8, 16, and 17.Pearson's correlation and mediation analysis are used to explore the relationship between student life management and academic performance by using SPSS and the PROCESS macro.Mediation analysis revealed that hangout with friends played a significant role as a mediator in the relationship between life management and academic performance.Life management also positively impacts CGPA and significantly reduces the failure rate.The results also state that sleep and time management correlate positively with academic performance, while mental and food management correlate negatively with academic performance.Mental and physical health are important contributors to overall well-being, including academic performance.Therefore, it is important to ensure that both are managed effectively.This study provides insight into the steps involved in large educational data mining, which help the researcher make a decision for future potential data mining research using large datasets.

Analytic tools are useful for detecting patterns in education data and providing insights about student performance and learning. This study compared six supervised learning algorithms (linear regression, ridge regression, the lasso, regression trees, random forests regression, gradient boosted regression) and identified features important for predicting student performance. The dataset consisted of N=1044 observations from two secondary schools in Portugal (UCI-MLR, Cortez & Silva, 2008). Performance was assessed by final grades (range: 0-20) in two courses, mathematics and Portugese. The models were fit to training data with 27 independent variables and evaluated on a testing subset. Overall, performance was lower for students in mathematics than Portugese. The models selected a similar set of variables as important for predicting performance: mother's education level, student plans for higher education, and weekly study time were positively related to predicted performance, whereas course subject, school educational support, and romantic relationships were associated with decreased student performance. The models differed in the number, weighting, order and importance given to predictor variables. Linear regression provided a model with 13 predictors. Ridge regression shrank the coefficient estimates toward zero; the lasso performed variables selection for a model with 20 predictors. There was a tradeoff between model complexity and interpretability. The single pruned regression tree provided a simple, interpretable non-linear model with four features. Random forests regression and gradient boosting reduced overfitting, but were more difficult to interpret. Advantages and limitations of the different models are discussed. Applications for educational data mining (EDM) and learning analytics (LA) are considered.

Educational Data Mining (EDM) is an emerging research field concerned with the application of data mining, machine learning, and statistics in the discipline of education. Many researchers have already focused on EDM and exploring the educational data using several traditional data mining techniques to improve the educational performance of the students by extracting the concealed patterns and predicting the final outcome. In this study, we aim to propose a Deep Neural Network (DNN) based model to predict the final CGPA of the undergraduate business students with a minimal error than the traditional approaches. We have considered the performance of a decision tree model as the baseline performance. Experiments in this study have shown that our proposed DNN model can predict the CGPA with a significantly minimal error rate. To measure the performance of our model we have considered the three evaluation metrics namely Mean Squared Error (=0.008), Mean Absolute Error (=0.067), and Mean Absolute Percentage Error (=2.074). Our proposed model has successfully shown a promising prediction performance by reducing the MSE, MAE, and MAPE by 0.0146, 0.0431, and 6.043 respectively, compared to the baseline model.

In the domain of adaptable educational environments, our study is dedicated to achieving three key objectives: forecasting the adaptability of student learning, predicting and evaluating student performance, and employing aspect-based sentiment analysis for nuanced insights into student feedback. Using a systematic approach, we commence with an extensive data preparation phase to ensure data quality, followed by applying efficient data balancing techniques to mitigate biases. By emphasizing higher education or educational data mining, feature extraction methods are used to uncover significant patterns in the data. The basis of our classification method is the robust WideResNeXT architecture, which has been further improved for maximum efficiency by hyperparameter tweaking using the simple Modified Jaya Optimization Method. The recommended WResNeXt-MJ model has emerged as a formidable contender, demonstrating exceptional performance measurements. The model has an average accuracy of 98%, a low log loss of 0.05%, and an extraordinary precision score of 98.4% across all datasets, demonstrating its efficacy in enhancing predictive capacity and accuracy in flexible learning environments. This work presents a comprehensive helpful approach and a contemporary model suitable for flexible learning environments. WResNeXt-MJ’s exceptional performance values underscore its capacity to enhance pupil achievement in global higher education significantly.
