제7차 교육과정은 수학과 교수-학습의 중심 원리로 구성주의 이론을 들고 있다. 그리고 학습방법 면에서도 탐구 학습, 자기 주도적 학습, 협동 학습을 통해서 정말 쉬우면서도 재미있는 활동 중심의 수업이 되도록 교과서를 구성하고 있는데 이러한 교과서 편찬 방향이나 교수-학습 방법도 구성적 방법에 그 뿌리를 두고 있다. 이러한 구성주의적 요소들이 투입된 교수-학습 방법은 관심 있는 교사들에 의해 이미 다양하게 이루어지고 있다. 그들에게 수업 과정의 단계화, 지식 구성의 위계화를 이루는 데 도움을 주고, 교수-학습 방법의 기준이 될 교수-학습 모델을 제시할 필요가 있다. 또한 이 모델을 적용한 수업 사례를 들어 지식의 구성 과정을 살펴봄으로써 모델의 적용 과정을 이해하도록 하여야 한다.

This project aims to design and develop a prototype for an agent that support online collaborative learning. Online collaborative learning, which has emerged as a new form of education in the knowledge-based society, is regarded as an effective method for improving practical and highly advanced problem-solving abilities. Collaborative learning involves complicated processes, such as organizing teams, setting common goals, performing tasks, and evaluating the outcome of team activities. Thus, a teacher may have difficulty promoting and evaluating the entire process of collaborative learning, and a system may need to be developed to support it. Therefore, to promote interaction among learners in the process of collaborative learning, this study designed an extensible collaborative learning agent (ECOLA) for an online learning environment.

This paper presents a neural net type process model for enhancing learning compensation function in hot strip finishing rolling mill. Adequate input and output variables of process model are chosen, the proposed model was designed as single layer neural net. Equivalent carbon content, strip thickness and rolling speed are suggested as input variables, and looper's manipulation variable is proposed as output variable. According to simulation result using process data to show the validity of the proposed process model, neural net type process model's outputs give almost similar data to process output under same input conditions.

본 연구에서는 학습 과정을 고려하여 지역지리의 교육 내용을 구성하는 원리를 도출하고자 시도하였다. 학습 과정에 대한 기존의 견해들은 학습이 진행되는 과정에서 새로운 지식이 누적되는 과정을 강조하는 입장과 새로운 지식이 기존의 사고들에 따라 조직되는 과정을 강조하는 입장으로 구분지을 수 있다. 그러나 이러한 두 가지 견해들은 학습 과정을 靜態的인 것으로 가정한다는 문제점을 지니고 있다. 본 연구에서는 기존의 학습한 지식과 새롭게 학습하는 지식 간의 순환적인 상호작용이 존재하며, 학생들은 態動的인 構成的 過程을 통하여 知識을 지니게 된다는 견해를 대안으로 제시하였다. 이러한 견해를 지역지리 교육에 적용하면 학생들의 私的 地理와 公的 地理 간의 循環을 강조하게 되며, 따라서 본 연구에서는 학생들의 生活世界에 대한 私的 地理로부터 교육 내용을 구성해야 한다고 제시하였다.

Purpose: The purpose of this study was to increase prediction accuracy for an anomaly interval identified using an artificial intelligence-based time series anomaly detection technique by establishing a pre-processing process. Methods: Significant variables were extracted by applying feature selection techniques, and anomalies were derived using the TadGAN time series anomaly detection algorithm. After applying machine learning and deep learning methodologies using normal section data (excluding anomaly sections), the explanatory power of the anomaly sections was demonstrated through performance comparison. Results: The results of the machine learning methodology, the performance was the best when SHAP and TadGAN were applied, and the results in the deep learning, the performance was excellent when Chi-square Test and TadGAN were applied. Comparing each performance with the papers applied with a Conventional methodology using the same data, it can be seen that the performance of the MLR was significantly improved to 15%, Random Forest to 24%, XGBoost to 30%, Lasso Regression to 73%, LSTM to 17% and GRU to 19%. Conclusion: Based on the proposed process, when detecting unsupervised learning anomalies of data that are not actually labeled in various fields such as cyber security, financial sector, behavior pattern field, SNS. It is expected to prove the accuracy and explanation of the anomaly detection section and improve the performance of the model.

This study proposed task-based teaming strategies as a means of fulfilling the demands and goals of the 7th national science curriculum. Task-based learning is based on the use of a series of activities whereby a teacher presents students with tasks related to daily lift and the students solve the tasks by themselves using various methods and thought processes and then present and discuss their results with each other. The tasks are selected from the 6-grade science textbook, are reconstructed and are then given to the classes. The tasks include whole class activities as well as individual activities related to the interests, abilities, and concerns of the students. The purpose of this study was to verify the effects of task-based learning classes on the science process skills and the scientific attitudes of elementary school students, when applied to 6th grade students. For this, the task-based learning activities were applied to an experimental group and expository teaching was applied to the comparison group. Both groups were given a pre-post test on science process skills and scientific attitudes. The results indicate that task-based loaming is very effective in the development of science process skills and scientific attitudes.

This study was conducted to understand and analyze experience of learning process support toward mothers of children who suffer from Cerebral Palsy, to generalize and structurize the meaning of practical learning process support, and to use the study results as basic materials for development of support model. Study subjects were 12 mothers who have Cerebral Palsy children attending an ordinary school and a school for handicapped children. Data were collected from November 10, 1999 to December 29, 2000 and from January 20 to March, 2001, for 2 months. Data were collected from un-structural and open questions. And the collected data were analyzed with the phenomenological analysis method proposed by van Kaam(1969). Study results obtained from this report were as follows; As for original materials about learning process support experience of cerebral palsy children's mothers, 48 technical expressions were derived from 97 pieces of original materials, they were categorized into 10 common elements. Those common elements were , , , , , , , , , . Based on the above results, it is suggested that the concept of learning process support toward children suffering from Cerebral Palsy should be structureized, and proper models should be developed.
