This article is devoted to investigating young learners' understanding of elapsed time from socio-cultural perspectives. The socio-cultural perspective benefits to access and personalize mathematics learning as how to have a mathematical object to be able to realize signifiers with the help of many other mathematical words and mediators. In terms of the realization of signifiers, I analyzed performances on elapsed time tasks of students in Grades 3 (n=115) and interviewed focal students. Quantitative analysis on students' performance identified that students perform differently when the task provided with the analog clock signifier. It suggested that students might think in a different way upon the given signifier even for the same elapsed time, especially when given as the analog clock. Qualitative analysis on focal students' interviews visualized how the students' understanding were different by displaying individual realization trees on elapsed time. The particular location of the analog clock signifier on each realization tree provided a personalized explanation about low performance on the task with analog clock signifier. The finding suggested that the realization of a specific signifier could be a key point in elapsed time understanding. I discussed why a majority of students face difficulty in elapsed time learning indicated analog clock and the advantage of moving elapsed time strands to higher grades in the school mathematics curriculum.

The objective of this study was to conduct a 'Theory of Home Economics Education' class using online problem-based learning(PBL) for prospective home economics(HE) teachers. The aim was to enable teachers to analyze the learning experience in the classroom, and to prepare operational strategies for online PBL on this basis. In order to achieve this, online PBL was applied to 31 students participating in the 'Theory of Home Economics Education' at the Department of HE in a university in Seoul, and the results were collected from the learning process. This also involved a reflective journal, a survey on the learning experience and the impacts was conducted. Moreover, analysis was undertaken on the learning activities, learning difficulties, and improvements. The main research results are as follows. Firstly, students accessed Webex, an online video conferencing program, and performed two PBL tasks: 'Making Home Economics Promotion Materials' and 'Presenting Teaching Strategies to Improve Learner's Immersion in Online Classes'. Secondly, learners established their own identity of HE learned about the HE class plans themselves. They also encountered realistic experience as HE teachers and learned communication and collaboration skills. Furthermore, they acquired creative problem-solving and self-directed learning ability, community consciousness, as well as the attitude of consideration and respect. Thirdly, students lacked knowledge of learning content and encountered difficulty in solving data research, analysis processes, and unstructured problems. They were affected by a lack of time and encountered problem in communicating with other team members in an online environment. As an improvement in online class operation, it was considrered necessary to reduce the learning burden by securing time and reducing the number of assignments, as well as to explain active interaction with instructors and PBL.

This study observes not only how much those who studied Statistics during the college years feel that Statistics is difficult but also why they felt it was difficult. Most of the targeted researchers, 80.8 percent, say "Statistics was difficult". They selected the item "textbooks were hard to understand" as the main reason (62.5%). Based on the explanatory survey of text books, many textbooks do not distinguish the small letter, x from the capital letter, X. Hence, in this study, one of the main reasons why most of the researchers felt Statistics was difficult must be the ambiguousness of the notations. If authors keep in mind the importance of the difference between capital letters and small letters in Statistics, the Statistics learners' recognition of difficulty of Statistics will decline.

As the importance of software has become more widely recognized, many Korean universities are designating software classes as an essential subject. However, there is a difficulty in achieving the educational goal because the education is done without sufficient understanding of the non-Major learner. Therefore, in this paper, we analyze the opinions of the humanities college students who have taken the software basic education course and confirm the changes of the students' digital minds. Based on this, we suggest considerations for the basic software education for non-Majors. The results of the analysis show that pre-admission software education does not contribute much to university education, while students respond positively to the practice-based education using student-oriented project subjects. Therefore, it is desirable to provide an environment where learners can gradually develop their digital minds by providing students with more software access opportunities based on hands-on practice in basic software education for non-Majors.

Recently, as awareness of the need for software education has spread worldwide, the government of Korea has led compulsory software education also. Basic software education in universities has been stabilized through various trials and efforts. However, due to software classes are mandatory, students not only could not have motivation for learning but also have treated programming course as a difficult subject. In this paper, two programming classes, which were designed and managed as a problem-oriented programming class for the purpose of cultivating computational thinking for the non-computer science students, are compared using the lecture assessment results. As a result, in the case of expanding the use of the problem as a grammatical explanation aid and expanding the ratio of major-friendly problems, the student's responses were concentrated on higher scores and the response average improved by about 7%. It means that the level of difficulty experienced by learners is lowered.

The purpose of this study is to ermine the effect of digital storytelling as a strategy of programming education to improve students' learning motivation and achievement. To overcome the difficulty of programming education in elementary school and find teaching method which derives the students' motivation, we used a digital storytelling in programming class. Digital storytelling that is considered as an important factor of edutainment gives interest to learners with interaction and stories for programming materials. The result is that elementary school students are more interested in programming and attend actively and their motivation and achievement is improved. Therefore it can gives elementary school students a positive experience with programming that will hopefully contribute to a more positive attitude towards computer science.

WBI (Web-Based Instruction), a web-based tool for teaching the students at a long distance, makes possible to Interact between learners and instructors, provides a wide variety of learning materials, has an advantage of overcoming spatial constraints. In this paper, as a model of using the web for education, a web-based education-evaluation system has been designed and implemented. Web-based education-evaluation system has to be equipped with both of the online setting question mode and the upload setting question mode, the former makes questions on web and the latter uploads the setted questions on offline with settling a defeat of the existing systems on setting questions. And the system has to be equipped with the function of analyzing the questions that gives teacher several kinds of analysis information and makes possible to feedback to questions by adjusting the difficulty and revising the questions. In this paper, a system that reflects the above requirements has been designed and implemented with PHP script language and MySQL database system.

The term project executed at the university is a learner-centered learning method in which students select their topics, draw up their plans, and produce results by themselves based on the content they have learned during the semester. Through the term-end project of the subjects relating software, students learn various techniques for the programming language and produce the outcomes of their project by the creative program development process. However, non-computer majors who take software course as liberal arts subjects have difficulty in understanding the programming language, so it is necessary to provide feedback from their professor for encouraging students in carrying out their projects smoothly. Therefore, a feedback method by the discussions between a professor and learners that can be applied to the term-end project of programming subject for the non-computer majors is proposed. The proposed method was apply to the actual term-end projects and the meaningful results were confirmed through the analysis of the project processes and outcomes.

As Web technology and functions have recently changed to a user-focused paradigm, new studies are being conducted to construct dynamic learning content that enables the learner's participation and continuous learning in the field of e-learning research and design. This paper covers a study on the degree of difficulty in learner-focused dynamic learning contents to provide efficient learning environments for its adaptation to e-learning 2.0. This study suggests DLA (Dynamic Level Adjustment) to provide learner-focused contents. The suggested system will be a guideline to control and adopt learning content that can be easily applied to the environmental change, and more in-depth future research can be performed by using the system. A dynamic learning content model was made to recognize various learning patterns of learners as a result of the performance evaluation.

The purpose of this study was to analyze the cliche for English-Korean interpretation and translation training with special reference to the cliche based on Shakespeare's works texts. The term of 'idioms' are generally used as figurative expressions instead of the term of 'cliche'. Thus, cliches must be reinterpreted in the lexicon that are used in useful expressions. Cliches are often idioms. Idioms are figurative phrases with an implied meaning; the phrase is not to be taken literally. This causes difficulty when translating to another language because the meaning may not be understood by people within that culture. Cliches are figurative or literal expressions and are overused expressions. Consequently, the cliches are distinguished from the idioms by the transparent meanings. This study was examined based on the cliches shown in Shakespeare's works texts. After all, anyone who wants to become an efficient English learners, interpretor and translator should be familiar with cliches. They had better use the cliche in English learning site. I hope this study will be helpful even a bit to his attempt.
