We held a self-education based student exchange program (Biotechnology Camp), inviting Nanyang Polytechnic (NYP) in Singapore. One of the main purposes of this activity was to encourage the students to open their eyes to "Global" , which is an essential sense for the next generation engineers regardless of nationalities. There were three quite simple but effective self-education based approaches that enabled us to achieve the main goal.1. A recognizable self-education based task: After a lecture on phytochemicals, we provided the students with a task that they must select, with a specific reason, a local material to evaluate its total polyphenol content. This self-education based task showed a great power to generate join forces among the students because the task was simple enough to be well shared by the students, who are interested in tropical food biochemistry.2. Cross-cultural training: We prepared a self-education based cross-cultural task to motivate the participants to realize a meaning of "Global" that we recognize as follows; accept and co-work with people who have different styles of thinking and doing. They should introduce their own culture and we have realized that this was effective to get the ONCT students to realize the nationality of NYP students and vice versa.3. Dormitory life as usual: During the entire period, all the students stayed at the student dormitory under the exactly same rules as usual. The dormitory was a small community, which is full of Japanese common senses, and thus it was an ideal location for them to teach and learn, in a self-educational manner, phenotypes and nature of each culture.
