Unesa.ac.id, SURABAYA-Postgraduate UNESA holds the Opening Ceremony and Plenary Session The 8th Southeast Asia Design Research International Conference (SEA-DR 2021) and The Second of The International Conference on Science, Technology, Education, Art, Culture, and Humanity (STEACH 2021) on 20-21 October 2021. The opening ceremony was packaged in plenary and parallel discussions attended by resource persons from foreign universities.
Prof. Hiroki Fujii, Ph.D, one of the speakers from Okayama University Japan, conveyed about the acceleration of teacher education for education in Asia. In detail, he delivered a science class experiment for education with the topic of using biodiesel for grades 11-12 chemistry. Utilization of bio-energy as renewable energy is one of the latest social issues in Japan, bio-diesel as a kind of bio-energy is an alternative fuel to diesel produced from oil plants. "For example, colza oil and coconut, and it is produced by transesterification of colza oil," he explained.
Hiroki also conducted experiments with his students, resulting in the generation of bio-diesel by transesterification of colza oil with methanol and identification of bio-diesel by thin layer chromatography (TLC). Measurement of calorific value, viscosity and flash point between colza oil, bio-diesel and diesel. He also added about the success of his experiment. "Funding and management partnerships and network programs that focus on and teach the evaluation process to student participants as a tool to learn and continue research improvisation in the future," he said.
Meanwhile, a resource person from the National Institute of Education, Nanyang Technological University Singapore, Dr. Toh Tin Lam also conveyed the results of his research on empowering students in mathematics through problem solving. Problem solving has been an important part of mathematics since Polya, and was at its highest in the 1980s and 1990s in many countries. “Recently, researchers have turned away from problem solving. Perhaps, there are not many success stories in teaching problem solving,” he said.
Toh Tin Lam also gives examples of how to solve problems that apply in mathematics classrooms. "Understand the problem, make a plan and implement the plan," he explained. Problem solving that applies in mathematics classrooms is practical mathematics, which is a set of "practical" mathematics lessons in the process of solving mathematical problems with a teaching framework. "Motivating students to learn mathematics with the help of problem solving is interesting, students are increasingly active in finding problems and learning mathematics and new things," he said.
