This paper which is directed to constructing the cognitive model of knowledge acquisition in view of the increasing need of globalization-oriented study, points out features of globalization-oriented study, and proposes the importance and necessity for constructing the CMKAGS (cognitive model of knowledge acquisition in globalization-oriented study) which includes attention, background knowledge, and chunking memory that involves semantic chunking, information encoding as well as choice of information encoding. The cognitive model of knowledge acquisition in question aims at helping e-learners to memorize their learned knowledge and improve their studies effectively and efficiently, whether they study in enhanced conditions or in natural conditions 展开更多

The purpose of the present research was to develop an innovative knowledge-based hyper-multimedia to promote a culture of using information and communication Technology (ICT) creatively for adolescents. Their learning processes and attitudes toward such innovation in their community were also examined. Thirty juveniles, 13-18 years of age in each Hangdong and Maerim districts, Chiang Mai province were employed in the study. Data collections were made through questionnaires, interview, test, group discussion and brainstorming. Analysis and evaluation were carried out with the applications of sufficient economy philosophy, constructivism theory and Torrance's future problem-solving instructional model. Results showed that the learning innovation of hyper-multimedia presented by the use of animation, video, scene and sound with related action script synchronization was considerably effective. With the application of sufficient economy philosophy, the result indicated that performance efficiency (El/E2) was 92.228/9.83 and the adolescents learning processes and attitudes were very good. These included purchasing of moderate ICT equipments, information screening for self-immunity and creative using of internet and ICT morally and ethically according to the computer laws. This independent learning system was properly designed for the juveniles with the right to retrieve the data or stop using at anytime. By using Torrance's approach and constructivism theory emphasizing on brainstorming techniques, it was noted that learning process was very well adopted by the adolescents with high satisfaction. They had good attitudes toward the extension of sufficient ICT cultural using in their community with emphasis on brotherly relationship. Related organizations should educate their parents to instruct the juveniles to use the internet properly and encourage people to be aware of ICT business in order to protect social and cultural problems encountered in the future. 展开更多
