- Universitas Negeri Semarang (UNNES) hosted a Guest Lecture by Mr. Nguyen Duc Dat, M.Ed. from Hanoi National University of Education, focusing on data literacy and scientific communication for Physics and Primary Education students.
- The session, part of the English for Academic Purposes course led by Dr. Ellianawati, aligned with SDG 4: Quality Education, emphasizing inclusive and equitable learning.
- The event reflected UNNES’s commitment to global academic excellence, supporting innovation (SDG 9) and international collaboration (SDG 17) through cross-border educational engagement.
The Faculty of Mathematics and Natural Sciences at Universitas Negeri Semarang (FMIPA UNNES) was successful in organizing a Guest Lecture presenting the international speaker, Mr. Nguyen Duc Dat, M.Ed. from Hanoi National University of Education, Vietnam. The online session was conducted via Zoom with the theme 'Data Representation and Visualization in Educational Contexts'.
The event was attended by students from the Physics Education Study Program and the Master’s Program in Primary Education, who are currently taking the course English for Academic Purposes taught by Dr. Ellianawati. The academic activity provided another opportunity to foster students' competencies for data literacy and scientific communication, as articulated in SDG 4: Quality Education, ensuring that all people receive inclusive and equitable quality education.
The event was opened with a prayer followed by a welcome speech from Dr. Ellianawati, who then introduced the guest lecturer. Mr. Nguyen Duc Dat, M.Ed., is a lecturer at the Department of Physics Education, HNUE, and is currently pursuing his doctoral studies at the University at Albany, United States. In this lecture, Mr. Dat shared his experience and insights in the field of educational research and innovative learning practices.
Mr. Dat earned both his Bachelor's and Master's degrees in Physics Education from HNUE. His research interests include STEM education, ICT integration in teaching, active learning, physics experiments, and the development of Arduino-based lessons on Thermophysics. His work embodies the spirit of SDG 9: Industry, Innovation, and Infrastructure, especially in encouraging innovation and technology-based approaches to education. He is a recipient of the Vingroup Innovation Foundation Scholarship VINIF.2022.ThS.022 and has several papers published in reputable international journals, among them Science & Education and EURASIA Journal of Mathematics, Science, and Technology Education.

During the lecture, Mr. Dat and Dr. Ellianawati took students through an interactive discussion on data visualization techniques; these included bar charts, line graphs, scatter plots, histograms, and box plots. Students were encouraged through practical examples to get involved in selecting the appropriate forms of representation of data and to interpret, critically, relationships between variables.
A short quiz during the session and a post-test at the end of the lecture were assigned to check students' comprehension. The results indicated that students were able to understand and retain most of the materials. Dr. Ellianawati praised Mr. Dat: "The presentation was obvious and easy for the students to follow, at the same time allowing them broader insights into various forms and techniques of data representation".
It concluded with a group photo and the dissemination of a video link on data misrepresentation, which is important to ensure accuracy and ethics in presenting scientific data, an integral part of not only educational integrity but also responsible innovation.
This Guest Lecture was part of a collaborative research in 2025 under the International Matching Grant Scheme led by Dr. Ellianawati. The collaboration includes six universities from six different countries, including HNUE, and is sponsored by DPA LPPM UNNES 2025. This partnership continues to cement the collaboration between UNNES and HNUE Vietnam in academic internationalization in line with the spirit of SDG 17, Partnerships for the Goals, which calls for global partnership to further education and research.
This guest lecture demonstrates how UNNES is committed continuously to developing sustainable and globally connected academic excellence across Southeast Asia by fostering innovation, or SDG 9; promoting quality science education, or SDG 4; and enhancing global partnership, or SDG 17.
