본 연구는 전통적인 교사위주의 설명식 수업을 벗어나 인터넷을 학습에 보다 효과적으로 활용하는 방법을 모색해 보고자 하는 것이다. 이를 위해 인터넷을 통하여 정보를 수집한 후에 그 내용을 재구성하여 홈페이지를 구축한 후 실험수업을 실시하였다. 실험수업의 결과 전통적인 수업반보다 인터넷 홈페이지를 활용한 수업반 학생들의 학업성취수준이 훨씬 높게 나타났다. 한편 인터넷 홈페이지를 활용한 실험수업밥의 겨우 구조적 수업반에 비해 비구조적 수업반 학생들의 학습성취도가 더 높게 나타났으나 그 차이는 유의적이지 않았다. 또한 수업 흥미도, 만족도, 학습의욕 등에도 실험반 학생들은 상당히 긍정적인 평가를 보였다. 본 연구를 통해 지리수업의 학습효과를 높이고 학생들의 흥미도를 높이기 위해서는 인터넷을 활용하는 수업형태가 바람직하다는 결과를 도출하였다. 특히 본 연구를 통해 앞으로 학생들의 학업성취도와 흥미도를 높이기 위해 인터넷을 수업에 활용하는 교수-학습설계의 개발이 필요함을 보여 주었다.

In this paper we propose a new Hybrid learning rule applied to multilayer feedforward neural networks, which is constructed by combining Hebbian learning rule that is a good feature extractor and Back-Propagation(BP) learning rule that is an excellent classifier. Unlike the BP rule used in multi-layer perceptron(MLP), the proposed Hybrid learning rule is used for uptate of all connection weights except for output connection weigths becase the Hebbian learning in output layer does not guarantee learning convergence. To evaluate the performance, the proposed hybrid rule is applied to classifier problems in two dimensional space and shows better performance than the one applied only by the BP rule. In terms of learning speed the proposed rule converges faster than the conventional BP. For example, the learning of the proposed Hybrid can be done in 2/10 of the iterations that are required for BP, while the recognition rate of the proposed Hybrid is improved by about $0.778\%$ at the peak.

The purpose of this study is to investigate a structural relationship among elementary students' self-determinant learning motivation, teaching-presence and learning outcomes (learning satisfaction, persistence) in blended learning environment. Participants were 5th and 6th grade students who enrolled in a mathematics learning service. The results showed that self-determinant learning motivation had direct effect on teaching presence, learning satisfaction and learning persistence. Teaching Presence had an direct effect on learning satisfaction and learning satisfaction had an direct effect on learning persistence. Based on the results, proper strategies were recommended to facilitate self-determinant learning motivation and teaching presence before and during learning since they play critical roles for the success of elementary students learning outcomes in a blended learning environment.

With the development of Internet technology, the construction and spread of network environment increased educational adaption and utilization based on World Wide Web. Learners are educated in the competitive, individual, or collaborative learning structure. Among them, competitive and individual educational methods are criticized for bringing about excessive competition and a lack of cooperation. As a new way of educational method, the interest for the collaborative learning structure was increased. In this perspective, we design and implement a web-based collaborative learning system which is adapted the merit and model of collaboration learning and show that the proposed system improves learning achievement and motivation by experimental study on student groups.

The prior data structure coursewares have been limited to using a simple screen structure with text, pictures or plain animation so that they have been failed to promote favorable interaction between learners and instructors, and unnecessarily charges the screen. In order to overcome these problems, this paper provides an applet-based simulation environment which enables learner to operate and control the data structure operation with their own data, therefore, the learners can actively and positively participate in a study with this courseware. The instructors can easily deliver the education contents to the learners by using web simulation suitable for IT education media. Also, the courseware can offer a class feedback and required data for students estimation by recording a log.

It has been found that the learning method based on conventional CAI(Computer Assisted Instruction) to be inadequate and inefficient as it is designed without considering the individual learning characteristics of the learners. In order to rectify and remedy the problem, the development of an ITS(Intelligent Tutoring System) that is adequately equipped with an artificial intelligence that successfully interprets the individual learning ability characteristics through accumulated individual data is in order. This study attempts to verify the individual acquisition ability and the possible error committed by learners in the process of learning in order to present the elements to be considered for designing a successful student module that enables the effective learning through the 'learner ability grouping' for learning Electronic Calculator Architecture.

This study has examined the structural relationship among factors related to the effects of flipped learning using the structural equation modeling. Two hundred thirty-six middle school and high school students were participated in this study. This study's results are as follows. First, looking through how much the flipped learning variables affect achievement, motivation affects achievement the most, and then interaction, participation come next. Second, looking through how much the flipped learning variables affect personality, interaction affect personality the most, and then teaching attitudes come next. Third, as a result of verifying the research model, the hypothetical model indicating relationship among motivation, participation, teaching attitudes, interaction and achievement, personality is valid.

The purpose of the study was to reveal the effects of visual organizer types and cognitive styles in electronic text understanding. 126 graduate students were divided into a field-dependent group and a field-independent group, and then assigned to two different types of web- based instruction programs which included visual organizers of 'reduction' type and 'abstraction' type. Regarding the comprehension of contents, there were no significant effects of visual organizer types and cognitive styles. However, it was revealed that there were significant interaction effects between visual organizer types and cognitive styles on the awareness of structure in electronic texts. That is to say, while Type 2 ('abstraction' type) was more effective to field-dependent learners, Type 1 ('reduction' type) was more effective to field-independent learners in awareness of structure in electronic texts.

시계열 자료를 분석할 때 쉽게 접근하는 통계적 방법은 ARMA 모형이며 신경망 학습 방법 중에서는 다층 퍼셉트론에서의 Back-propagation 알고리즘이 일반적이다. Back-propagation을 비롯한 신경망 학습의 구조는 자료의 특성에 따라 경험적으로 결정하는 것으로 알려져 있다. 그러나 바로 이 점이 신경망 학습방법의 이용을 어렵게 하는 요인이기도 하다. 본 연구는 ARMA 모형 중 몇 개 유형의 자료에 대하여 Back-propagation 알고리즘을 적용함에 있어 어떠한 구조로 학습하는 것이 효율적인가를 입력층과 은닉층의 크기, 활성화 함수를 중심으로 검토하였다.

본 연구에서는 시계열자료를 예측하기 위해 적용한 n$\times$n$\times$1 신경망 구조에서 초기값의 시각적인 선택을 통한 개선된 학습과정을 제안한다. 적용된 Easton[1]의 제어상자는 시각적인 면과 실용적인 적용측면에서 다차원 구조를 논의하기에는 제한적이지만, 적은 개수의 은닉노드를 갖는 단순한 신경망구조에서는 초기 가중값들의 동적인 선택을 통하여 가능한 빨리 효과적인 학습이 이루어질 수 있게 할 수 있다. 신경망 학습의 오차 판단기준은 기존의 평균제곱오차(MSE)를 고려한다. 실증연구에는 모의생성된 ARMA(1,0) 자료와 담배생산량 자료를 이용한다.
