Semarang, October 25, 2025 \u2014 The Faculty of Mathematics and Natural Sciences at Universitas Negeri Semarang (FMIPA UNNES) successfully hosted a Guest Lecture featuring international speaker Mr. Nguyen Duc Dat, M.Ed., from Hanoi National University of Education (HNUE), Vietnam.<\/p>\n\n\n\n

The online session, conducted via Zoom, carried the theme \u201cData Representation and Visualization in Educational Contexts.\u201d<\/em> The event was attended by students from the Physics Education Study Program and the Master\u2019s Program in Primary Education, who are currently enrolled in the English for Academic Purposes course taught by Dr. Ellianawati.<\/p>\n\n\n\n

The event began with a prayer and welcoming remarks 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. During the lecture, Mr. Dat shared his experience and insights in the field of educational research.<\/p>\n\n\n\n

Mr. Dat earned both his Bachelor\u2019s and Master\u2019s degrees in Physics Education from Hanoi National University of Education. His research interests include STEM education, ICT integration in teaching, active learning, physics experiments, and the development of Arduino-based lessons on Thermophysics. He is also a recipient of the Vingroup Innovation Foundation Scholarship (VINIF.2022.ThS.022). He has published several papers in reputable international journals, including Science & Education and the EURASIA Journal of Mathematics, Science, and Technology Education<\/em>.<\/p>\n\n\n\n

During the lecture, Mr. Dat and Dr. Ellianawati guided students through an interactive discussion on various data visualization techniques, including bar charts, line graphs, scatter plots, histograms, and box plots. Through practical examples, students were encouraged to understand how to select appropriate forms of data representation and to critically interpret relationships between variables.<\/p>\n\n\n\n

To assess students\u2019 understanding, a short quiz was given during the session, followed by a post-test at the end of the lecture. The results indicated that students were able to comprehend and absorb the materials effectively.<\/p>\n\n\n\n

Dr. Ellianawati expressed her appreciation to Mr. Dat, stating that \u201cthe presentation was obvious and easy for students to follow, while also providing them with broader insights into various forms and techniques of data representation.\u201d<\/em><\/p>\n\n\n\n

The activity concluded with a group photo and the sharing of a video link about data misrepresentation, emphasizing the importance of accuracy and ethics in presenting scientific data.<\/p>\n\n\n\n

This Guest Lecture was part of a collaborative research initiative under the 2025 International Matching Grant Scheme, led by Dr. Ellianawati. The research collaboration involves six universities from six different countries, including HNUE, and is funded by DPA LPPM UNNES 2025. Through this activity, UNNES and HNUE Vietnam continue to strengthen their international academic partnership, fostering innovation and enhancing the quality of science learning and STEM education across Southeast Asia.<\/p>\n","protected":false},"excerpt":{"rendered":"
