Big data for monitoring educational systems
This report considers “how advances in big data are likely to transform the context and methodology of monitoring educational systems within a long-term perspective (10-30 years) and impact the evidence based policy development in the sector”, big data are “large amounts of different types of data produced with high velocity from a high number of various types of sources.” Five independent experts were commissioned by Ecorys, responding to themes of: students' privacy, educational equity and efficiency, student tracking, assessment and skills. The experts were asked to consider the “macro perspective on governance on educational systems at all levels from primary, secondary education and tertiary – the latter covering all aspects of tertiary from further, to higher, and to VET”, prioritising primary and secondary levels of education
Toward Precision Education: Educational Data Mining and Learning Analytics for Identifying Students’ Learning Patterns with Ebook Systems
Precision education is now recognized as a new challenge of applying artificial intelligence, machine learning, and learning analytics to improve both learning performance and teaching quality. To promote precision education, digital learning platforms have been widely used to collect educational records of students’ behavior, performance, and other types of interaction. On the other hand, the increasing volume of students’ learning behavioral data in virtual learning environments provides opportunities for mining data on these students’ learning patterns. Accordingly, identifying students’ online learning patterns on various digital learning platforms has drawn the interest of the learning analytics and educational data mining research communities. In this study, the authors applied data analytics methods to examine the learning patterns of students using an ebook system for one semester in an undergraduate course. The authors used a clustering approach to identify subgroups of students with different learning patterns. Several subgroups were identified, and the students’ learning patterns in each subgroup were determined accordingly. In addition, the association between these students’ learning patterns and their learning outcomes from the course was investigated. The findings of this study provide educators opportunities to predict students’ learning outcomes by analyzing their online learning behaviors and providing timely intervention for improving their learning experience, which achieves one of the goals of learning analytics as part of precision education

Modeling Student Affective State Patterns during Self-Regulated Learning in Physics Playground
This dissertation research focuses on investigating the incidence of student self-regulated learning behavior, and examines patterns in student affective states that accompany such self-regulated behavior. This dissertation leverages prediction models of student affective states in the Physics Playground educational game platform to identify common patterns in student affective states during use of self-regulated learning behavior. In Study 1, prediction models of student affective states are developed in the context of the educational game environment Physics Playground, using affective state observations and computer log data that had already been collected as part of a larger project. The performances of student affective state prediction models generated using a combination of the computer log and observational data are then compared against those of similar prediction models generated using video data collected at the same time. In Study 2, I apply these affective state prediction models to generate predictions of student affective states on a broader set of data collected from students participants playing Physics Playground. In parallel, I define aggregated behavioral features that represent the self-observation and strategic planning components of self-regulated learning. Affective state predictions are then mapped to playground level attempts that contain these self-regulated learning behavioral features, and sequential pattern mining is applied to the affective state predictions to identify the most common patterns in student emotions.
Findings from Study 1 demonstrate that both video data and interaction log data can be used to predict student affective states with significant accuracy. Since the video data is a direct measure of student emotions, it shows better performance across most affective states. However, the interaction log data can be collected natively by Physics Playground and is able to be generalized more easily to other learning environments. Findings from Study 2 suggest that self-regulatory behavior is closely associated with sustained periods of engaged concentration and .self-regulated learning behaviors are associated with transitions from negative affective states (confusion, frustration, and boredom) to the positive engaged concentration state.
The results of this dissertation project demonstrate the power of measuring student affective states in real time and examining the temporal relationship to self-regulated learning behavior within an unstructured educational game platform. These results thus provide a building block for future research on the real-time assessment of student emotions and its relationship with self-regulated learning behaviors, particularly within online student-centered and self-directed learning contexts
Exploring the Effectiveness of AI Algorithms in Predicting and Enhancing Student Engagement in an E-Learning
The shift from traditional to digital learning platforms has highlighted the need for more personalized and engaging student experiences. In response, researchers are investigating AI algorithms' ability to predict and improve e-learning student engagement. Machine Learning (ML) methods like Decision Trees, Support Vector Machines, and Deep Learning models can predict student engagement using variables like interaction patterns, learning behavior, and academic performance. These AI algorithms have identified at-risk students, enabling early interventions and personalized learning. By providing adaptive content, personalized feedback, and immersive learning environments, some AI methods have increased student engagement. Despite these advances, data privacy, unstructured data, and transparent and interpretable models remain challenges. The review concludes that AI has great potential to improve e-learning outcomes, but these challenges must be addressed for ethical and effective applications. Future research should develop more robust and interpretable AI models, multidimensional engagement metrics, and more comprehensive studies on AI's ethical implications in education
Analyzing the behavior of students regarding learning activities, badges, and academic dishonesty in MOOC environment
Mención Internacional en el título de doctorThe ‘big data’ scene has brought new improvement opportunities to most products and services,
including education. Web-based learning has become very widespread over the last decade,
which in conjunction with the Massive Open Online Course (MOOC) phenomenon, it has enabled
the collection of large and rich data samples regarding the interaction of students with these educational
online environments.
We have detected different areas in the literature that still need improvement and more research
studies. Particularly, in the context of MOOCs and Small Private Online Courses (SPOCs),
where we focus our data analysis on the platforms Khan Academy, Open edX and Coursera. More
specifically, we are going to work towards learning analytics visualization dashboards, carrying
out an evaluation of these visual analytics tools. Additionally, we will delve into the activity and
behavior of students with regular and optional activities, badges and their online academically
dishonest conduct. The analysis of activity and behavior of students is divided first in exploratory
analysis providing descriptive and inferential statistics, like correlations and group comparisons,
as well as numerous visualizations that facilitate conveying understandable information. Second,
we apply clustering analysis to find different profiles of students for different purposes e.g., to analyze
potential adaptation of learning experiences and pedagogical implications. Third, we also
provide three machine learning models, two of them to predict learning outcomes (learning gains
and certificate accomplishment) and one to classify submissions as illicit or not. We also use these
models to discuss about the importance of variables.
Finally, we discuss our results in terms of the motivation of students, student profiling,
instructional design, potential actuators and the evaluation of visual analytics dashboards
providing different recommendations to improve future educational experiments.Las novedades en torno al ‘big data’ han traído nuevas oportunidades de mejorar la mayoría
de productos y servicios, incluyendo la educación. El aprendizaje mediante tecnologías web se
ha extendido mucho durante la última década, que conjuntamente con el fenómeno de los cursos
abiertos masivos en línea (MOOCs), ha permitido que se recojan grandes y ricas muestras de
datos sobre la interacción de los estudiantes con estos entornos virtuales de aprendizaje.
Nosotros hemos detectado diferentes áreas en la literatura que aún necesitan de mejoras y del
desarrollo de más estudios, específicamente en el contexto de MOOCs y cursos privados pequeños
en línea (SPOCs). En la tesis nos hemos enfocado en el análisis de datos en las plataformas Khan
Academy, Open edX y Coursera. Más específicamente, vamos a trabajar en interfaces de visualizaciones
de analítica de aprendizaje, llevando a cabo la evaluación de estas herramientas
de analítica visual. Además, profundizaremos en la actividad y el comportamiento de los estudiantes
con actividades comunes y opcionales, medallas y sus conductas en torno a la deshonestidad
académica. Este análisis de actividad y comportamiento comienza primero con análisis
exploratorio proporcionando variables descriptivas y de inferencia estadística, como correlaciones
y comparaciones entre grupos, así como numerosas visualizaciones que facilitan la transmisión
de información inteligible. En segundo lugar aplicaremos técnicas de agrupamiento para encontrar
distintos perfiles de estudiantes con diferentes propósitos, como por ejemplo para analizar
posibles adaptaciones de experiencias educativas y sus implicaciones pedagógicas. También proporcionamos
tres modelos de aprendizaje máquina, dos de ellos que predicen resultados finales
de aprendizaje (ganancias de aprendizaje y la consecución de certificados de terminación) y uno
para clasificar que ejercicios han sido entregados de forma deshonesta. También usaremos estos
tres modelos para analizar la importancia de las variables.
Finalmente, discutimos todos los resultados en términos de la motivación de los estudiantes,
diferentes perfiles de estudiante, diseño instruccional, posibles sistemas actuadores, así como la
evaluación de interfaces de analítica visual, proporcionando recomendaciones que pueden ayudar
a mejorar futuras experiencias educacionales.Programa Oficial de Doctorado en Ingeniería TelemáticaPresidente: Davinia Hernández Leo.- Secretario: Luis Sánchez Fernández.- Vocal: Adolfo Ruiz Callej
