고대 이후로 수학은 끊임없이 발전되어 왔고, 지금도 발전 지향적인 변화가 이루어지고 있다. 수학을 발전적 관점에서 보는 것은 기존의 수학적 지식을 답습하여 그 기능을 익히는 것보다는 수학을 끊임없이 창조, 발전시키는 대상으로 생각하는 것이다. 수학에서 발전적 학습은 대상을 고정된 것으로 보지 않고, 하나의 결과가 얻어졌더라도 보다 더 나은 방법을 알아본다거나 또는 이를 바탕으로 보다 일반적인, 보다 새로운 것을 발견하려는 것이다. 이러한 발전적 수학학습은 증명과 반박의 과정, What if not, 관점의 변경, 부정에 의한 방법 등을 통해서 이루어 질 수 있다. 본 연구에서는 발전적인 수학학습에 대한 다양한 이론을 고찰하고 특히, 부정을 통한 발전적 학습 전개의 방법 및 과정에 대하여 분석함으로써 발전적 수학학습에 대한 방향을 탐색해 보고자 한다.

This study is to find strategies to promote distance learning effectiveness in the online learning environment. The research showed that the level of learner's perception of the structure of transactional distance was not significantly different according to sex (p>.05). There was significant correlation between the level of learner's perception of the structure and academic satisfaction(p<.01). And, the level of learner's perception of the structure and learning durability appeared to have statistically significant correlation. However there was no significant difference(p>.05) between academic achievement. Among the three subordinate factors, the course interaction organization had the most influence on the learner's academic satisfaction and the learner's learning durability was influenced the most by the content organization.

The purpose of this study were to identify the effect of thesis-writing activity based project method on the ability of girl's middle school student's self directed learning(SDL) and learning attitude. To achieve above study purpose, the subject of this study were selected 60 from second-grade students of reading club(thesis-writing activities participants 30, non-participants 30), applied a program based project method to experimental group, to carry out a pre-post examined targeting two-group with early making a SDL ability and learning attitude inventory, and the results of the data were analyzed by t-test using the SPSS(Ver. 18). The results were as follows: In the aspect of SDL ability development by thesis-writing activity, the student participant showed somewhat significant differences compared to the non-participants. First, a openess, inner-motivation, autonomy, self-conception of SDL ability was significantly higher than those non-participants. Second, confidence, success expert, attention, effectiveness, affection of learning attitude was significantly higher than those non-participants. These results represent that various programs, which can develop SDL ability and learning attitude, can be provided for youth when they join any thesis-writing activity based project method in general and those programs are also very effective in developing SDL ability and learning attitude of juveniles. Furthermore, It is suggested that thesis-writing activity based project method are a necessary element at the school education fields.

Due to the increasing demand and importance of non-face-to-face education, open online learning platforms are getting interests both domestically and internationally. These platforms exhibit different characteristics from online courses by universities and other educational institutions. In particular, students engaged in these platforms can receive more learner autonomy, and the development of tools to assist learning is required. From the past, researchers have attempted to utilize process mining to understand realistic study behaviors and derive learning patterns. However, it has a deficiency to employ it to the open online learning platforms. Moreover, existing research has primarily focused on the process model perspective, including process model discovery, but lacks a method for the process pattern and instance perspectives. In this study, we propose a method to identify learning patterns within an open online learning platform using process mining techniques. To achieve this, we suggest three different viewpoints, e.g., model-level, variant-level, and instance-level, to comprehend the learning patterns, and various techniques are employed, such as process discovery, conformance checking, autoencoder-based clustering, and predictive approaches. To validate this method, we collected a learning log of machine learning-related courses on a domestic open education platform. The results unveiled a spaghetti-like process model that can be differentiated into a standard learning pattern and three abnormal patterns. Furthermore, as a result of deriving a pattern classification model, our model achieved a high accuracy of 0.86 when predicting the pattern of instances based on the initial 30% of the entire flow. This study contributes to systematically analyze learners' patterns using process mining.

추천 시스템에서부터 1:1 마케팅에 이르는 전자 상거래의 다양한 응용 영역에서, 개별 사용자로부터 개인화된 사용자 프로파일을 구축하는 것은 매우 중요하다. 이러한 프로파일들은 사용자들의 구매 행위와 같은 개인별 행동들을 설명해주며, 특히 다양한 데이터 마이닝(Data Mining) 기술들을 이용해 사용자의 거래 기록으로부터 학습된 규칙들을 발견해낼 수 있다. 발견된 규칙들 중에는 거짓이거나 연관 없거나 또는 하찮은 것들도 존재하기 때문에, 가장 중요한 문제 가운데 하나는 발견된 규칙들을 처리후-분석을 어떻게 수행하느냐이다. 예를 들어, 발견된 규칙을 사용자 프로파일에 적합한 것인지를 확인할 때 좋은 규칙과 나쁜 규칙을 어떻게 판명하는가 하는 문제이다. 이 논문에서는 규칙을 확인하는 과정에서 객관적 척도를 이용하는 방법을 제안하였다.

The purpose of this study was to investigate the role of calculators as a cognitive tool rather than calculating tool in learning elementary school mathematics. The calculator activities on multiplying two numbers ending with 0s or two decimal fractions and mixed four operations were developed, and exploratory lessons with the activities were implemented to three 3rd graders and two 5th graders. The results were shown that calculators provided an alternative effective learning environment: students were able to use heuristic thinking, reason inductively and successfully investigate principles of mathematics through the pattern recognition. And finally, we discussed the heuristic method through utilizing calculators.

The aims of this study are to investigate how Kepler found a scientific problem for the retinal image theory and to investigate how the science high-school students respond when the same situation is applied to them. And their results was compared with general high-school students' results. Kepler found the scientific problem in the eye vision through the critical analysis of contemporary theories of vision, based on his relevant knowledge of optics. When we applied the same situation to the Korean science high school and general high-school students, only a few of science high-school students found the scientific problem as same as Kepler's finding. From the results, it is suggested that in development of creativity teaching material, the situations like Kepler's problem finding need to be included in the programs.

It is necessary, due to changes in the information environment, to investigate problems in existing information retrieval systems. Ontologies and social tagging, which are a relatively new means of information organization, enable exploratory discovery of information. These two connect a thought of a user with the thoughts of numerous other people on the Internet. With these connection chains through the interactions, users are foraging information actively and exploratively. Thus, the purpose of this study is, through qualitative research methods, to identify numerous discovery facilitators provided by ontologies and social tagging, and to create an exploratory discovery model based on them. The results show that there are three uppermost categories in which 5, 4 and 4 subcategories are enumerated respectively. The first category, 'Browsing and Monitoring,' has 5 sub categories: Noticing the Needs, Being Aware, Perceiving, Stopping, and Examining a Resource. The second category, Actively Participating, has 4 categories: Constructing Meaning, Social Bookmarking and Tagging, Sharing on Social Networking, Specifying the Original Needs. The third category, Actively Extends Thinking, also has 4 categories: Social Learning, Emerging Fortuitous Discovery, Creative Thinking, Enhancing Problem Solving Abilities. This model could contribute to the design of information systems, which enhance the ability of exploratory discovery.
