The instructors encouraged learners to build up the knowledge by themselves via active learning activities. The sampling group for this study consisted of 80 second year undergraduate students studying at the Department of Printing and Packaging Technology, Faculty of Industrial Education and Technology, King Mongkuts University of Technology Thonburi. The students could access the museum by downloading the data from the internet and learn by themselves using an avatar to enter the museum. In each exhibition room of the museum for packaging, there were different kinds of packaging along with relevant information. After visiting the museum, the students needed to take a test before going out. The students had to gain at least 85% correct points. The instructors could know each students behaviors and their progress by the developed software. They could control the activities by using mouse and keyboard. Visitors activities were also recorded such as date and time of participation. The research results in this phase revealed that the students visiting the virtual reality museum for packaging on the internet showed interest and enthusiasm in learning more. Besides, the students had more time to gain training outside classroom and to learn according to their preferences everywhere and every time. It was found that most students were satisfied with the virtual reality online museum for packaging.

Virtual reality for packaging folding practice

This paper presents an application of a virtual reality for packaging folding practices. The system presented an interactive folding package practice in a virtual space. A structure of virtual paper was defined in three-dimensional (3D) virtual space and was displayed on a graphic screen. The steps of folding were controlled by the system in which students must select specific components to be folded in sequences. If they select a component correctly, the system will show the folding animation of the selected components. On the other hands, if students select a wrong component, the system will warn students and their scores will be deducted. In addition, the system will go back to the first step if students make a mistake more than 20 percents. Students can use a folding tutorial if they want to study the folding process and other information. After students pass the folding practice with the purposed system, they can try with a real structure paper. The result shows that students can fold packages more rapidly and it can use fewer papers in folding practices.

The objectives of this study were to create the database for self-learning in the knowledge related to the polymer packaging for food, and to evaluate the qualities and satisfaction of the users. The information and details on polymer types and packaging types were searched to show in the database which was design using the program of MySQL, phpMyAdmin, AppServ, Apache 2.2. The qualities of database were evaluated by 3 experts in packaging and 3 experts in database using questionnaire of 5-rating scale. The samples of user consisted of 40 undergraduate students in related field, selected by simple random sampling to evaluate the satisfaction in database. The results showed that the qualities of content, illustration, and text design were good because the average scale evaluated by the experts in packaging and database were 4.00, 4.33, 4.38, respectively. The qualities of database design and website presentation were very good because the average scale evaluated by the experts in database were 4.72 and 4.59 respectively. The average scale of satisfaction was 4.39, indicating that the database highly satisfy the users. Therefore, the database can be applied for education and dissemination to the public for self-learning in polymer for food packaging.

Work in progress - collaborative learning for Packaging Design using KM and VR

The purposes of this research were to develop online collaborative learning with the application of knowledge management and virtual reality technology for the course in packaging design in order to find solutions to the issues of insufficient time spent for instruction in classroom, resulting in lack of proper practice, and paper waste for the design, resulting in high cost. The sampling group for this study was composed of 30 third year undergraduate students studying at the Department of Printing and Packaging Technology, Faculty of Industrial Education and Technology, King Mongkuts University of Technology Thonburi. The students were divided into groups of 2-3 persons. Each member in the same group, when logged in, would enter their own working space and could see their pieces of work, which they were doing, at the same time in 3 dimension format. Each member in the same group could help one another to design the assigned packaging. They could control their packaging design by using mouse and keyboard. They could also discuss via chatting system or microphone. Their records for activity participation would be made automatically, for example, their date and time of logging in, and transcripts of their conversation. The test at the moment reveals that learners who participated in online collaborative learning showed more interest and enthusiasm in learning. Moreover, learners had more time to practice outside classroom and reduced a large waste of paper.
