The thesis presents a novel approach to adaptive courseware generation, named PCG. This approach adopts its structure from existing intelligent e-learning systems and introduces a new component called pedagogical model to support pedagogical flexibility in the process of courseware generation. The process is carried out in three steps. The first step allows the selection of a pedagogic scenario that better matches to the learner’s characteristics. The second step allows the generation of a courseware plan whose structure is featured by the selected pedagogic scenario, while the third step enables the generation of adaptive courseware content by substantiating the courseware plan with appropriate resources. The generated courseware is a sound courseware satisfying the design constraints imposed by the learner, knowledge domain, and pedagogical models. PCG prototype was experimentally evaluated using user study. The overall results of the experiment study demonstrated the satisfaction of learners with the system and proved a significant improvement in the learning gain.
본논문은적응형코스웨어형성(Pedagogically-driven Courseware Generation: PCG)을위한새로운접근법을제시한다. 본접근법은이미존재하고있는지능형 e-러닝시스템의구조를적용하였으며, 코스웨어발생과정에서의교육학적유연성을뒷받침할교육학적모델 (pedagogical model)이라고불리는새로운구성요소를도입하였다. 코스웨어의형성은 1) 학습자의특성에가장알맞은교수법의선택; 2) 선택된교수법에따른코스웨어계획의형성; 3) 적합한자원을활용하여코스웨어계획을실체화하는적응형코스웨어콘텐트의개발; 의 3가지단계로이루어진다. 해당단계를통해학습자, 지식영역, 그리고교수법에의한디자인제약들을만족하는사운드코스웨어가개발되었으며, 개발된 PCG 프로토타입은사용자연구에의해실험적으로평가되었다. 실험적연구를통해, 개발된시스템에대한학습자의만족과학습이득의유의미한향상이입증되었다.
