The purpose of this thesis was to implement effective blended PBL(Problem-Based Learning) systems for information communication ethics education. The proposed systems, Online learning and face-to-face classes were systematically combined and Moodle is used for online learning platform. We proposed the use of wikis and blogs not just for creation of knowledge, but as active learning tool to support PBL. In the proposed system, learners used the web 2.0 as a open place to create new knowledge and experience various effects of PBL, such as (1) Improvement of problem solving ability, (2) Understanding of cooperative learning. The blended PBL systems with teaching and learning model were evaluated learners' level of satisfaction and educational achievement in the study of information communication ethics. The result shows that blended PBL learning method is more effective in cultivating consciousness of information communication ethics and showed more higher level of learners' satisfaction and educational achievement than the face-to-face PBL learning method.

One of the problems with testing for the presence of $CO_2$ is that the results are not visible. In order to over-come this weak point, a new testing method was developed with BTB indicator equipment, that made the gas visible. After that, the experiment was performed and tested the effects of the new visible equipment. The visible equipment could be adapted to regular class use successfully. Also, it was effective in that it reduced waste of gas, minimized danger potential through use of $CO_2$ canisters and candle-sticks, and also increased knowledge about indicators. The new experimental method and equipment affected the students' interest. It is possible that the students' positive participation was due to their interest in the new apparatus and application of the visual senses. The new system was tested fer its effects on teaching content and helping to produce sustained memory of the content. There were no significant differences between the groups in terms of content learning on initial content memory. However, when students in both groups were tested 4 months later, the visual experiment group sustained memory performance, while the other group showed a significant decrease. Generally, boys score higher than girls in terms of interest and participation in experimental activities. In this case, however, there were no difference between groups. It may have been due to introduction of new equipment and different methods from the textbooks. So, this could increase participation in science using various experiments.

Recently, there are studies the argument that arithmetic rules established by the four fundamental arithmetic operations, in other words, commutative laws, associative laws, distributive laws, should be explicitly described in mathematics textbooks and the curriculum. These rules are currently implicitly presented or omitted from textbooks, but they contain important principles that foster mathematical thinking. This study aims to evaluate the current level of understanding of these computation rules and provide implications for the curriculum and textbook writing. To this end, the correct answer ratio of the five arithmetic rules for 1-4 grades 398 in five elementary schools was investigated and the type of error was analyzed and presented, and the subject to learn these rules and the points to be noted in teaching and learning were also presented. These results will help to clarify the achievement criteria and learning contents of the calculation rules, which were implicitly presented in existing national textbooks, in a new 2022 revised curriculum.

Problem/Project based learning(PBL) is a student-centered teaching method in which students collaboratively solve problems and reflect their experiences. According to the results of PBL study and the experiences of the authors in PBL instruction, this paper introduced the necessities, output and significance of learning process PBL evaluation method and sums up our PBL evaluation process. The issue of appropriate and fair evaluation has been raised in untact (non-contact) university mathematics education due to the novel coronavirus (COVID-19) of the year 2020. To this end, when we had the course on for the summer semester held at S University in the summer of 2020. To ensure the fairness in evaluation and to improve the quality of our college math education, the PBL evaluation method was fully adapted. As a result, most of the students who took the lecture have learned a wide range of related knowledge without a single exception, and students agreed it is an ideal, fair, rational, and effective evaluation method applicable to other online courses in the era of untact education. This case was summarized in detail and introduced in this paper.

The algorithm is a chain of mechanical procedures, capable of solving a problem. In modern mathematics educations, the teaching algorithm is performing an important role, even though contracted than in the past. The conspicuous characteristic of current elementary mathematics textbook's manner of manipulating multiplication algorithm is exceeding converge to 'standard algorithm.' But there are many algorithm other than standard algorithm in calculating multiplication, and this diversity is important with respect to didactical dimension. In this thesis, we have reconstructed the experimental learning and teaching plan of multiplication algorithm unit by making the best use of diversity of multiplication algorithm. It's core contents are as follows. Firstly, It handled various modified algorithms in addition to standard algorithm. Secondly, It did not order children to use standard algorithm exclusively, but encouraged children to select algorithm according to his interest. As stated above, we have performed teaching experiment which is ruled by new lesson design and analysed the effects of teaching experiment. Through this study, we obtained the following results and suggestions. Firstly, the experimental learning and teaching plan was effective on understanding of the place-value principle and the distributive law. The experimental group which was learned through various modified algorithm in addition to standard algorithm displayed higher degree of understanding than the control group. Secondly, as for computational ability, the experimental group did not show better achievement than the control group. It's cause is, in my guess, that we taught the children the various modified algorithm and allowed the children to select a algorithm by preference. The experimental group was more interested in diversity of algorithm and it's application itself than correct computation. Thirdly, the lattice method was not adopted in the majority of present mathematics school textbooks, but ranked high in the children's preference. I suggest that the mathematics school textbooks which will be developed henceforth should accept the lattice method.

In this study, we analyzed the influences of lecture design using CoRe upon the professor's teaching professionalism in the aspects of pedagogical content knowledge (PCK). The participants are three professors from the college of science-engineering located in Chungcheong-do. After collecting their syllabi, we observed their lecture and conducted the orientation. Afterward, we collected the CoRes which they prepared before the lecture. Then we observed their lecture and conducted semi-structured interviews. This process was carried out twice. We analyzed their syllabi, CoRes, videotaped lectures, field notes, the teaching materials, and interview transcripts. The results revealed that professors not only clarified the learning objectives and the characteristics of students but also reflected them in the lecture. In addition, they established the teaching strategies according to the characteristics of contents in the unit. As they recognized the necessity of understanding students' achievement, they selected the assessment method and applied it in the lecture. In some cases, however, they lacked presenting learning objectives specifically and explained students' misconceptions without inducing new concepts. They also presented a shortage of considering students' prior knowledge. They lacked providing students with an opportunity to participate in lectures, and their assessment method was not effective. Based on the results, we discussed implications to improve teaching professionalism using CoRe.

This study suggested an educational curriculum(12 class periods) in order for higher level elementary school students to learn programming in discretionary activity hours using a line tracer and evaluated achievement level based on the outcome of learning by class period to assess the possibility of success. As a result, it could confirm that the programming learning using the line tracer was more excellent in creativity than the computer programming learning. In addition, it has been found that the programming learning method using the line tracer had a potential to be successful as a new creative tool that could replace the computer.

The purpose of this study is to identify the difference in learning styles, learning stages, and preferred nursing specialties between two groups of nursing programs, regular BSN and RN-BSN. The survey instrument was a simplified version of the Kolb's Learning-Style Instrument which was developed by the researcher, a self- reported learning style questionnaire with twelve questions related to the four learning stages. The sample of the study was the 218 nursing students in a university in Korea which consisted of 58 junior and 67 senior students in the regular BSN program, and 58 junior and 35 senior students in the RN-BSN program. Main findings of the study were as the following. 1) Over all, the major learning style was either the diverger or the accomodator; the most preferred learning stage was the concrete experience and the leastly preferred learning stage was the abstractive conceptualization learning stage; and the most preferred nursing specialty in the future was the clinical nursing. 2) Students in the BSN program preferred four learning stages with rather equal proportion, whereas the students in the RN-BSN program preferred the concrete experience learning stage as high as 60.3% and the abstractive conceptualization learning stage as low as 9.5%. 3)For the future career, the junior students of both programs preferred clinical and educational nursing areas, and the senior students of both programs preferred clinical and research areas. The main reason of the difference seemed to result from the different courses such as Health Education or Teaching Method for the juniors and the Nursing Research for the seniors of both groups. Because the sample of the study was limited to a university, it is difficult to generalize the study results for the entire nursing students in Korea. Continuous studies with larger numbers of nursing students and nurse educators, and experimental studies measuring the effects of new curricula are needed for the future.

Digital Technology actively utilized in all spheres by rapid changes in information and knowledge demands transformations not only in the sociocultural and educational spheres but also specifically in the field of arts education. Digital Technology becomes a challenging factor for the field of arts education. In this study purposed a new teaching-learning approach method in arts education, called "Music Technology-Based Learning"(hereafter, MTBL), which is to, first, take interdisciplinary approaches combining various subjects in the field of arts education. In the case study was conducted to examine the educational effects of the MTBL approach to the liberal arts course in university: mind maps derived from 2 sessions (pre-class and post-class), evaluation sheets regarding self-directed learning and in-depth interviews with ten voluntary learners after the class were used as methods for data collection. The result of case study shows positive changes in the terms of the degrees of emotional sensibilities of the learners. Moreover, the research confirmed the potential of MTBL as a new teaching and learning methodology in art education.
