In this Paper, we design and implement an e-Learning system with dynamic learning contents Providing and re-time assignment system. The learner can select the dynamic learning contents Providing environments with test and Quiz Phase according to the learners' characters and interest to improve the learning effects. Also, we develop the real-time assignment system which is composed of multiple choice and essay test and can provide the interaction between teacher and learner immediately.

How can the educator help learners to learn? The old way was to tell learners as much as possible, passing on the educator's knowledge. Now the educator acts as a helper. She will organise experiences which allow the learners to do health behaviors, she may utilize instructional materials, she may write downsome questions for a group of learners to discuss. In all these ways the teachers is helping learning. Some educators feel that they must do all the talking themselves. They feel that they are not really teaching the learners some new information, but this is quite wrong. In fact if a educatorgives a lecture and learners do not learn, then the educator is talking not teaching. So the devlopment of instructional materials is much needed to be a learner education. And the selection of materials may be very important for the level of maturity of the learners in interest, complexity of ideas, opportunity for self-identification, speed of learners' ability to observe and length of concentration. Author studied the several instructional materials which can be utilized in the field of dental health education and also studied their values, limitations and considerations when they are used. The learning activities are poster, puppet, model, mock-up, specimen, flannel board, chalk board, bulletin board, psychodrama, role play, field trip, exhibition, laboratory method.

This paper proposes a Distributed Autonomous Robotic System(AIS) based on Artificial Immune System(AIS) and Distributed Genetic Algorithm(DGA). The behaviors of robots in the system are divided into global behaviors and local behaviors. The global behaviors are actions to search tasks in environment. These actions are composed of two types: dispersion and aggregation. AIS decides one among above two actions, which robot should select and act on in the global. The local behaviors are actions to execute searched tasks. The robots learn the cooperative actions in these behaviors by the DGA in the local. The proposed system is more adaptive than the existing system at the viewpoint that the robots learn and adapt the changing of tasks.

In this paper, we designed and implemented a practice-oriented simulation-type web courseware to learn the ‘Digital Circuits’ subject effectively. The implemented web courseware utilized multimedia elements such as graphics, animations, and voices etc. for improving understanding and interaction of learning. Also, the web courseware could be easily updated a learning information by using database built in a web server system. In result, the implemented web courseware could encourage a learner with a motive of learning and improve effects of learning. Also, a learner can widely learn because we can add various contents to database according to need. Furthermore, the web courseware could improve understanding for learning by offering feedback on the result.

It's known by recent surveys that many students have difficulty in understanding the concepts of programming algorithms, and don't feel interested in learning them. Dynamic programming, one of the most important and widely-used algorithms in computer science, is especially feared by students and unlike other algorithms, it also requires understanding of the process of problem solving and storage space design as well as basic principles of the algorithm. And so it has not been properly covered in classes. In this paper, we developed a visual simulator to solve the above problems in learning dynamic programming. This learning simulator is designed for students to run the algorithms themselves and learn how it works by visualizing each step of dynamic programming and corresponding states of storage space.

In this paper, it introduce how to operate the design 1 credit (one hour), containing in the experimental courses (2 credits and 3 hours) of "Basic Electronic Circuit Design and Experiment" and "Advanced Electronic Circuit Design and Experiment" in junior grade of Information & Control Engineering Advanced Course in Hankyong National University. The effective procedures, results, and improvements to operate the design 1 credit (one hour) in combination with the experimental one credit (2 hours), according to the engineering accreditation system, are introduced. To learn an effective design method, students have to learn completely the design courses according to a system diagram for completing design courses.

Developmental language disorder is the most common developmental disability in childhood, occurring in 5-8% of preschool children. Children learn language in early childhood, and later they use language to learn. Children with language disorders are at increased risk for difficulties with reading and written language when they enter school. These problems often persist through adolescence or adulthood. Early intervention may prevent the more serious consequences of later academic problems, including learning disabilities. A child's performance in specific speech and language areas, such as phonological ability, vocabulary comprehension, and grammatical usage, is measured objectively using the most recently standardized, norm-referenced tests for a particular age group. Observation and qualitative analysis of a child's performance supplement objective test results are essential for making a diagnosis and devising a treatment plan. Emphasis on the team approach system in the evaluation of children with speech and language impairments has been increasing. Evidence-based therapeutic interventions with short-term, long-term, and functional outcome goals should be applied, because there are many examples of controversial practices that have not been validated in large, controlled trials. Following treatment intervention, periodic follow-up monitoring by a doctor is also important. In addition, a systematized national health policy for children with speech and language disorders should be provided.

To get more natural synthetic speech generated by a Korean TTS (Text-To-Speech) system, we have to know all the possible prosodic rules in Korean spoken language. We should find out these rules from linguistic, phonetic information or from real speech. In general, all of these rules should be integrated into a prosody-generation algorithm in a TTS system. But this algorithm cannot cover up all the possible prosodic rules in a language and it is not perfect, so the naturalness of synthesized speech cannot be as good as we expect. ANNs (Artificial Neural Networks) can be trained to learn the prosodic rules in Korean spoken language. To train and test ANNs, we need to prepare the prosodic patterns of all the phonemic segments in a prosodic corpus. A prosodic corpus will include meaningful sentences to represent all the possible prosodic rules. Sentences in the corpus were made by picking up a series of words from the list of PB (phonetically Balanced) isolated words. These sentences in the corpus were read by speakers, recorded, and collected as a speech database. By analyzing recorded real speech, we can extract prosodic pattern about each phoneme, and assign them as target and test patterns for ANNs. ANNs can learn the prosody from natural speech and generate prosodic patterns of the central phonemic segment in phoneme strings as output response of ANNs when phoneme strings of a sentence are given to ANNs as input stimuli.

A programming language is very important subject in computer science. But it is difficult for many students to learn programming language. New pedagogical methods and techniques to help students to learn programming are needed. In this paper, we investigated the effects of Pair Programming, and we proposed a Pair programming strategy to improve programming skills. This paper examined the proposed Pair programming strategy. A empirical study showed the proposed teaching and learning strategy has positive effects on achievement and motivated strategies in programming course. Four factors - critical thinking, metacognitive reflection, effort regulation, and peer learning - have positive effects in learning strategies. The proposed Pair Programming strategy improves programming learning and motivated strategies.
