New pub: Using Accessible Motion Capture in Educational Games for Sign Language Learning

Conference, Multimodal Learning Analytics
A new publication will be presented at the EC-TEL conference 2023 in Aveiro, Portugal. "Using Accessible Motion Capture in Educational Games for Sign Language Learning" https://link.springer.com/chapter/10.1007/978-3-031-42682-7_74 Abstract Various studies show that multimodal interaction technologies, especially motion capture in educational environments, can significantly improve and support educational purposes such as language learning. In this paper, we introduce a prototype that implements finger tracking and teaches the user different letters of the German fingerspelling alphabet. Since most options for tracking a user’s movements rely on hardware that is not commonly available, a particular focus is laid on the opportunities of new technologies based on computer vision. These achieve accurate tracking with consumer webcams. In this study, the motion capture is based on Google MediaPipe. An evaluation based on user feedback shows that…

Keynote @ #JTELSS23 – Towards Highly Informative Learning Analytics

Conference, Feedback, Higher Education, Keynote, Learning Analytics, Learning Design, Summer School
Hendrik Drachsler delivered a keynote presentation at the 17th EATEL Summer School on Technology-Enhanced Learning (JTELSS 2023) in La Manga, Spain that unveiled groundbreaking insights from the Highly Informative and Learning Analytics (HILA) research program. This exciting initiative explores the effectiveness of HILA and the transformative power of data-enriched learning activities in providing highly informative feedback to students. Here a few highlights from Hendrik's keynote, showcasing the potential of HILA to revolutionize learning outcomes. The Power of Feedback Extensive research has long recognized the profound impact of feedback on learning success. Hendrik's presentation revealed that HILA surpasses traditional feedback methods by offering even higher efficacy. By going beyond simple right or wrong responses, HILA provides actionable feedback that enables students to exercise effective metacognitive control over their learning process. This…

HIKOF-DL Presentation at the University Future Festival

Conference, Event
  Jane, as the project-coordinator, presented HIKOF-DL in the Track - AI & Technology, at the University Future Festival on 27.4.2023. Abstract: During the COVID-19 pandemic, we made use of artificial intelligence and learning analytics technologies for both lecturers’ and students’ online teaching and learning gains. Using these technologies, the team designed and implemented novel ways of providing highly-informative competence driven feedback (hicof) to large classes of university students (≈1000) for three innovative online assignments. We built machine learning models to automatically assess the assignments and reduced the time required for staff to manually grade them. High-informative feedback provides correct solutions, possibilities for improvement, hints on self-regulation and effective learning strategies (Wisniewski, Zierer and Hattie, 2020; Winne & Hadwin, 2008), and on two different levels - Feed Up (concerning their understanding of the learning goal) and Feed Forward (concerning their next steps in their learning process) (Hattie & Timberley, 2007). Competence driven feedback is feedback that is given to students based on…

Paper and presentation about the topic of detecting disengaged reading at LAK23

Conference, Conference, Event, Higher Education, Publication, Research topic, Self-Regulation, Target group
At the recent Learning Analytics and Knowledge Conference (LAK23), Daniel Biedermann presented his paper "Detecting the Disengaged Reader - Using Scrolling Data to Predict Disengagement during Reading," to shed light on the potential for early detection of disengagement in readers. The paper presents a unique method for early disengagement detection that relies solely on the classification of scrolling data. By transforming scrolling data into a time series representation, each point of the series represents the vertical position of the viewport in the text document. Time series classification algorithms are then used to evaluate the data.The results were promising, with the method able to classify disengagement early with up to 70% accuracy. However, the study also observed differences in performance depending on which texts were included in the training dataset. Biedermann…

Highly Informative LA Workshop at LAK23

Highly Informative LA Workshop at LAK23

Conference, Higher Education, Learning Analytics, Learning Design, Workshop
On the 13th of March 2023, as part of the LAK23 conference, five EduTec team members (Daniele Di Mitri, Ioana Jivet, Sebastian Gombert, Atezaz Ahmad and Hendrik Drachsler) organised a full-day workshop on Highly Informative Learning Analytics with Marcel Schmitz from Zuyd University of Applied Sciences, The Netherlands. In this workshop, we investigated the concept of highly informative learning analytics and proposed a methodology for designing an environment that delivers highly informative learning analytics. The workshop is intended as a hands-on, interactive session that allows participants to test the methodology’s potential in a realistic use case. The proposed approach is based on the four-stage process of the Design Cycle for Education (DC4E). We exemplify practical tools that were designed in-house for each stage, including a tool to support teachers while…

The protection of students’ privacy in learning analytics (LA) applications is critical for cultivating trust and effective implementations of LA in educational environments around the world. However, students’ privacy concerns and how they may vary along demographic dimensions that historically influence these concerns have yet to be studied in higher education. Gender differences, in particular, are known to be associated with people's information privacy concerns, including in educational settings. Building on an empirically validated model and survey instrument for student privacy concerns, their antecedents and their behavioral outcomes, we investigate the presence of gender differences in students’ privacy concerns about LA. We conducted a survey study of students in higher education across five countries (N = 762): Germany, South Korea, Spain, Sweden and the United States. Using multiple regression analysis,…

Hendrik Drachsler gave a keynote @ the LDE CEL Annual Meeting under the theme ‘Developing a Culture of Learning Analytics'. Hendrik summarized the achievements of the Highly Informative and Learning Analytics (HILA) research program, that is the successor of the Trusted Learning Analytics research program conducted in Frankfurt, Germany.  After two years of digital annual meetings, finally CEL could invite again to their annual meeting 2022 at the CEL Teaching Lab. Among keynotes from Simon Buckingham Shum (University of Technology Sydney), and Alyssa Friend Wise (New York University), Hendrik presented the latest research outcomes on Highly Informative and Learning Analytics (HILA) research program. Highly informative and competency-based feedback is costly and can be best given in small teacher-to-learner settings. According to research, feedback has a powerful effect on learning success;…

Our paper titled "Caught in the Lifelong Learning Maze: Helping People with Learning Analytics and Chatbots to Find Personal Career Paths" was accepted at the 13th International Conference on Distance Learning and Education (ICDLE 2022) held at the University of Barcelona, Spain. Atezaz Ahmad participated in the conference and presented their publication. The article will be published (open access) in the International Journal of Information and Education Technology. Abstract: Current lifelong learning platforms offer users a query option to select a wide variety of courses. However, finding a suitable course among the seemingly endless catalogs of options presented by the platforms is not straightforward. We argue that digital counseling can enhance this process. In this paper, we present a set of three formative studies where we explored the main aspects…

Artificial Intelligence, Conference, Digitalisation
The journey from an initial idea to a finished product is generally known to be a long one. At least, this also seems to be the case with the implementation of AI systems that are intended to support various areas of everyday life. With regard to the automated understanding of language and images, AI models have made great progress in recent years and are being used in more and more applications, such as chatbots (see GUDI at Goethe University). The Educational Technologies team is therefore researching AI implementations in the education sector to support teachers and students, as well as to develop autodidactic learning environments.
