PhD defense: Congratulations, Dr. Manuel Valle Torre!

Artificial Intelligence, Higher Education, Learning Analytics, PhD defense, School

Today, 07.10.2026 at 15:00, Manuel Valle Torre successfully defended his PhD thesis "Sequences in Data to Represent Learning Processes: What have you tried until now?" at Delft University of Technology. Hendrik Drachsler was honoured to take part as an independent member of the doctoral committee. [pdf-embedder url="https://edutec.science/wp-content/uploads/2026/10/Manuel-defense-slides.pdf"] Manuel's thesis starts with a question every programming tutor knows: "What have you tried until now?" Digital learning environments usually assess only the final product, so this question is hard for them to answer. In three phases, Manuel shows how sequences of learner actions can be used to understand learning processes and support them while they happen. He developed ELAT for analysing edX log data, reviewed the field of learning sequence analysis, and studied problem-solving in data science notebooks. He then built JELAI,…

Congratulations, Dr. Karademir! Turning Data into Pedagogical Action

Alumni, Learning Analytics, PhD defense

On 1 July 2026, Onur Karademir successfully defended his doctoral dissertation at the Goethe-University Frankfurt — and we could not be prouder. Onur joined the EduTec team in February 2021, but his story started even earlier: as a student frustrated by 90-minute maths lectures, he channelled that experience into founding StudyCore, an EdTech startup delivering digital teaching tools to universities and schools. That hands-on instinct — building things that actually reach learners — defined his entire PhD trajectory. His dissertation, Turning Data into Pedagogical Action: Designing the Learning Analytics Cockpit, a Teacher Dashboard for Feedback, tackles one of the most pressing challenges in educational technology: making learning analytics useful in real classrooms. Over three interconnected studies — a proof of concept, a co-design process with secondary school teachers and a…

How AI Systems Impact Mathematics Achievement in Rural Areas

Artificial Intelligence, PhD defense, School

On Friday, May 8, 2026, Rashmi Khazanchi successfully defended her doctoral dissertation, "Artificial Intelligence in Education: Impact of AI-Based Systems on Mathematics Achievement," at the Open Universiteit in Heerlen. The defense was supervised by Prof. Dr. Hendrik Drachsler, who holds a guest professorship at the Open Universiteit, alongside co-promotor Prof. Dr. Daniele Di Mitri (German University of Digital Sciences). The Research Question Khazanchi's work addresses a pressing challenge in education: whether AI-based learning systems can help close the mathematics achievement gap for students from socioeconomically disadvantaged backgrounds. Her research focused on students in a rural school district in South Georgia, USA — a setting often characterized by limited resources and a shortage of qualified teachers. What Was Studied The school implemented two AI-based systems to support struggling learners: ALEKS, an…

PhD Defense: A Triumph in Learning Analytics: Congratulations, Dr. Atezaz Ahmad!

Award, PhD defense

The entire EduTec team warmly congratulates Atezaz Ahmad on his remarkable journey, as he has successfully defended his PhD thesis and now holds the distinguished title of Dr. Atezaz Ahmad. In a compelling and rigorous defense, Atezaz presented his groundbreaking research, titled: “Uncharted Territories: Learning Analytics Indicators from a Learning Design Perspective”. His PhD dissertation explores the intersection of Learning Design (LD) and Learning Analytics (LA) and addresses the long-standing challenge of their limited alignment. While LD focuses on structuring meaningful learning activities, LA provides data-driven insights into learning processes and outcomes, yet their connection has often remained fragmented. To bridge this gap, the thesis introduces the Learning Analytics and Design Alignment (LADA) framework, a comprehensive reference model that explicitly links LD principles with LA practices by connecting learning goals, activities,…

PhD Defense: Achieving Gender Equity in STEM Education With CSCL

Computer-supported collaborative learning, Gender, PhD defense

Our treasured colleague, Dana Kube, successfully defended her PhD thesis on November 29th at the Open University in Heerlen, Netherlands. We warmly congratulate Dr. Kube for her great academic achievements and advancements in the field of CSCL and gender research! In her dissertation titled “Gender & CSCL – Exploring the Relation of Computer-Supported Collaborative Learning (CSCL) and Gender Bias in Research and Practice”, Dana emphasizes that gender equity is not just a goal, but a necessity for sustainable development and illustrates the role of gender in research and practice. It remains a challenge to understand which aspects of gender are most important in research, and how to interpret findings in the context of pervasive gender stereotypes and biases. This issue is especially pressing in the field of STEM, where gender…

PhD Defense on Software Infrastructure for Contextualized Learning Analytics in Online Education

Learning Analytics, PhD defense

We warmly congratulate our esteemed alumni George-Petru Ciordas-Hertel on the successful defense of his PhD thesis this past Tuesday, 05.11.2024! Way to go, Dr. George! We are proud of you for achieving this milestone! At universities we have seen a big shift to online education in the past ten years, as universities have continuously integrated technology into educational environments. This development has brought students and educators new possibilities, but also challenges. A promising method is Learning Analytics (LA), which uses data to gain insights into learning behaviors and enhance educational outcomes. In his dissertation, George highlights a critical limitation in traditional learning analytics: they often overlook significant aspects of learners’ digital and physical environments. His research proposes that integrating contextual information from these environments could make LA even more effective.…

Successful PhD Defense: Understanding Self-Regulated Learning in Blended Learning Environments

Learning Analytics, PhD defense, School, Self-Regulation

On the 28th of June Hendrik Drachsler had the honor of being a jury member for the PhD defense of Esteban Villalobos at the University of Toulouse. Esteban successfully defended his thesis titled “Developing a Learning Analytics framework to understand the temporal behavior of students in Blended Learning Environments“. Especially in Blended Learning (BL) settings, Self-Regulated Learning (SRL) is crucial for student success. These environments require students to manage their learning not only in online, but also in traditional in-person activities. Esteban’s thesis advances our understanding of SRL in BL contexts through a comprehensive approach, using Learning Analytics (LA) techniques as well as the latest Sequence Analysis (SA) advancements to examine students’ behaviors via trace data and self-reported measures. One of the main goals of his thesis is the manifestation…

PhD defense on Technological Responses to Distracting Media Multitasking in Digital Learning Environments

Award, Higher Education, Learning Analytics, PhD defense, School, Self-Regulation

Today, we proudly acknowledge the remarkable achievement of our team member, Daniel Biedermann, in successfully defending his PhD thesis to become Dr. Biedermann. Woohoo, congratulations! In our modern world, the reality of digital distractions through the attention economy cannot be denied. Countries like the Netherlands, for instance, are planning to ban mobiles from classrooms starting from 2024. Daniel's PhD work centered on the complex challenges of digital media distraction, a phenomenon that's prevalent largely due to our pervasive use of social media and notification systems on our phones, PCs, and tablets. Presented in his disputation, Daniel argued the need for a context-sensitive system to gain a more profound understanding of digital media distraction. In addition, Daniel addressed the crucial subject of digital self-control tools (DSCTs). His research, which provided a…
