New Pub: Revolutionizing Essay Scoring with Hierarchical Rater Models

Artificial Intelligence, Assessment, Higher Education, Journal, New Pub

For a special issue on Natural Language Processing in Psychology we proposed a hierarchical rater model-based approach to address the challenges in automatic essay scoring. Essay writing tests are an integral part of educational systems, essential for assessing students' critical thinking, articulation and understanding. Since the manual scoring process requires significant resources and time, teachers are beginning to use Automated Essay Scoring (AES), which is potentially capable of alleviating the manual effort involved. #AutomatedEssayScoring #NaturalLanguageProcessing #FormativeAssessment #EducationalTechnology #MachineLearning #AIinEducation #HierarchicalRaterModel #EdTech #ScoringAutomation #AI #AssessmentTools #MeasurementInvariance #TransformerModels #EducationResearch #UniversityTesting #AIModels #TechInEducation There are an abundance of available models and each one has its own unique features and scoring methods. Thus, selecting the optimal model is complex and challenging, especially when different aspects of content have to be assessed over a number…

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…

New pub: Potentials and Challenges of Generative AI in Instruction and Research on Instruction

Artificial Intelligence, Feedback, General education, Journal, New Pub, School

Artificial Intelligence (AI) is becoming such a part of our daily lives that soon it will be almost impossible to imagine life without it. Especially since the emergence of ChatGPT and other Large Language Models, endless new possibilities have arisen for the usage of AI in many areas, especially in educational settings. Currently, the effective use of AI in education, both in teaching and learning, remains largely undefined, as do its limitations. We are also missing clarity regarding the potential benefits of AI for instructional research and the ethical boundaries of its use in this field. The opportunities and challenges associated with integrating AI into educational practices and research are explored in a newly published article from Hendrik Drachsler, Knut Neumann and Jochen Kuhn. In their paper they identify specific…

The earth’s biodiversity is being lost and the changing climatic conditions are causing species to migrate to new areas, both of which are transforming the agriculture landscape. Humans and their economic activities are contributing to these changes, which are referred to as planetary polycrises. There is still much to be learned about how these phenomena are connected to each other and how we humans and our economic practices contribute to them. Of essential significance is the unanswered question of what we can do to address these crises. An Interdisciplinary Approach to Global Challenges The Center for Critical Computational Studies…

From May 16th to 17th, 2024, Hendrik Drachsler and Marcel Schmitz (TETRA AI, ZUYD University of Applied Science) had the pleasure of providing a FoLA workshop at the College of Anaesthesiologists of Ireland (CAI) in Dublin, Ireland, under the support of the Insight research centre. Together with members from CAI and from the ASSERT Centre, College of Medicine and Health, University College Cork (UCC), they used the FoLA tool to plan a simulation-based training for high-risk clinical situations using highly informative feedback. Data from these trainings will be collected and analyzed to determine how effective this training is in improving the performance of the attendees. The study is being planned to take place with around 100 doctors in training at two simulation training centers: at ASSERT Centre UCC and at…

Recap of the MODUS conference in Karlsruhe

Artificial Intelligence, Conference, Higher Education

As the echoes of insightful discussions and the energy of networking gradually settle, it's time to revisit the highlights of the German Rectors’ MODUS Conference which took place an April 10th and 11th 2024 in Karlsruhe. The conference titled “Recognition Culture in Higher Education. International Perspectives on Lifelong Learning and Student Mobility” brought together around 200 experts and interested parties from universities and research institutions, including Hendrik Drachsler and other representatives from the Goethe University. The conference produced a wealth of insights into the integration of artificial intelligence (AI) at universities. Discussions highlighted both opportunities and challenges, especially in the context of the digitalization of administration and teaching organizations. Instruments for various areas of application were presented, including information and communication tools such as chatbots and recommendation systems, as well…

New Pub: Feedback sources in essay writing: peer-generated or AI-generated feedback?

Artificial Intelligence, Empirical Study, Feedback, Further Education, Journal, Publication

A newly published article discusses the use of peer feedback as a learning strategy, particularly in large classes where teachers face heavy workloads. For complex tasks like writing argumentative essays, peers may struggle to provide high-quality feedback due to the cognitive demands involved. The emergence of Artificial Intelligence (AI) tools, like ChatGPT, raises the question of whether AI can serve as a new feedback source for such tasks. To investigate this, a study compared ChatGPT-generated feedback with peer feedback on argumentative essays written by 74 graduate students from a Dutch university. The study collected essay data, peer feedback and ChatGPT-generated feedback, and then analyzed them using coding schemes. Results showed significant differences between ChatGPT and peer feedback, with ChatGPT offering more descriptive feedback while peers focused on identifying essay problems.…

CORE Roundtable in Munich

Assessment, Critical Online Reasoning, Multimodal Learning Analytics, Project, Project meeting

Hendrik Drachsler, Sebastian Gombert and Gianluca Romano participated at the Roundtable in Munich for the CORE project (Critical Online Reasoning in Higher Education) from 04.03.-05.03.2024. In those two days, our team had the chance to recapitulate on how the infrastructure stood strong during the first survey from December 2023 to February 2024, and pave the way for next steps and surveys. In summary, the infrastructure performed well. It dealt with approximately 10Mio. requests per seconds and the majority of hurdles participants reported were out of our authority. Requests from participants were dealt with quickly in a few days on average. Even though we are proud of our achievements there is still a lot to be done for future surveys. For the agenda we split into smaller groups, each of us…

Interview in Zeit Online: Cell Phone Bans in Schools

Digitalisation, Press, School

In an interview with Zeit Online, Hendrik Drachsler explains his views on digitalization and cell phone bans in schools. He outlines that the hurdles associated with digitalization should be taken seriously, but that he is also very critical of extreme demands such as a complete ban on digitalization in schools. In his eyes it is important to differentiate between the usage of private devices and devices provided by the schools. Studies show that the use of private devices during the school day can distract students from learning and lower their concentration rates, for example during the private consummation of social media. On the other hand, the usage of tablets and AI during class can bring added value to the teaching process, especially while teaching complex concepts and with the individualization…
