The characteristic of Web 2.0 is openness, participation, share, cooperation and creation. The purpose of this article was to identify learner based knowledge creation strategy through UCC in Web 2.0, to develop UCC by university students and to make systematic UCC process. This article suggested knowledge creation strategy with UCC learning Community of Practice(CoP). UCC was developed by 25 students who registered e-learning in "P" university and conducted interview with students and experts to analyze the contents which related with research questions. Systematic process for developing educational UCC was consisted of sectors such as idea creation, design, development, implementation and evaluation. Main developing process steps were as follows: making subject$\rightarrow$seeking information$\rightarrow$selecting data$\rightarrow$designing contents$\rightarrow$making story board$\rightarrow$planning of filming$\rightarrow$filming$\rightarrow$digitalizing$\rightarrow$editing$\rightarrow$reviewing final product$\rightarrow$implementing$\rightarrow$evaluating. For learner based knowledge creation through UCC, educational institutions have to provide platform for learners' need, and learners create diverse ideas with UCC CoP. This article suggested knowledge creation strategy with sharing collective intelligence through process of UCC design, development, implement and evaluation.

The goals of this study were to identify differences in learners' and teachers' perspectives on EFL learners' language anxiety, to identify the differences among teachers coping with learners' language anxiety, and to find how learners cope with their language anxiety. The research was effectuated by means of a survey questionnaire and interviews. The data were collected from 92 teachers and 230 students in four different school settings. There were the $6^{th}$ grade 50 primary school learners, the $2^{nd}$ grade 60 middle school learners, the $11^{th}$ grade 60 high school learners of, and the $2^{nd}$ and $3^{rd}$ grade 60 university learners. There were also 26 primary school teachers, 22 middle school teachers, 21 high school teachers, and 23 university teachers. The findings reveal that there were differences in responses among the respondents. The findings suggest that teachers need to pay attention to their particular learners' anxiety sources: especially in the case of primary school setting, the activity of answering teachers' questions for teachers was the primary source of learner's anxiety, in the case of middle school settings, translating sentences in English into Korean, in the case of high school setting, checking unknown vocabulary, and in the case of university settings, university learners felt anxious when classmates spoke fluently. The implications of the study indicate that these aspects should be handled carefully to motivate certain group of learners.

This paper suggests an e-learning system model, a goal-driven personalized e-learning system, which increase the effectiveness of learning. An e-learning system following this model makes the learner choose the learning goal. The learner's choice would lead learning. Therefore, the system enables a personalized adaptive learning, which will raise the effectiveness of learning. Moreover, this paper proposes a SCORM standard, which modifies SCORM 2004 that has been insufficient to implement the "goal driven personalized e-learning system." We add a data model representing the goal that motivates learning, and propose a standard for statistics on learning objects usage. We propose each standard for contents model and sequencing information model which are parts of "goal driven personalized e-learning system." We also propose that manifest file should be added for the standard for contents model, and the file which represents the information of hierarchical structure and general learning paths should be added for the standard for sequencing information model. As a result, the system could sequence and search learning objects. We proposed an e-learning system and modified SCORM standards by considering the many factors of adaptive learning. We expect that the system enables us to optimally design personalized e-learning system.

The main purpose of this study isto explore the potential of affective computing (AC) platforms in education through two phases ofresearch: Phase I - platform analysis and Phase II - classification of academic emotions. In Phase I, the results indicate that the existing affective analysis platforms can be largely classified into four types according to the emotion detecting methods: (a) facial expression-based platforms, (b) biometric-based platforms, (c) text/verbal tone-based platforms, and (c) mixed methods platforms. In Phase II, we conducted an in-depth analysis of the emotional experience that a learner encounters in online video-based learning in order to establish the basis for a new classification system of online learner's emotions. Overall, positive emotions were shown more frequently and longer than negative emotions. We categorized positive emotions into three groups based on the facial expression data: (a) confidence; (b) excitement, enjoyment, and pleasure; and (c) aspiration, enthusiasm, and expectation. The same method was used to categorize negative emotions into four groups: (a) fear and anxiety, (b) embarrassment and shame, (c) frustration and alienation, and (d) boredom. Drawn from the results, we proposed a new classification scheme that can be used to measure and analyze how learners in online learning environments experience various positive and negative emotions with the indicators of facial expressions.

This paper aims to propose teaching plans based on individual learner's experience and from a cross-cultural viewpoint by applying Currere as a method of Korean life-culture education. Current Korean culture education programs are not systematic, and are being executed without differentiation from language education. Thus, this study proposes Korean life-culture teaching plans based on the method of Currere. We suggested Currere teaching-learning stages and strategies for Korean language learners by adapting Pinar's and Jeong Seong-a's method of Currere. The Currere teaching-learning stages consisted of introduction, regression, progression, theme analysis, data analysis, group discussion, and integration. Although the method of Currere is implemented through autobiographic writing, this study added the strategies of 'personal experience telling' and 'schema utilization and background knowledge provision'. In order to enhance the applicability of Currere to Korean life-culture education, we suggested teaching plans for the theme of "How to dispose rubbish" as an example. We suggested detailed teaching plans that teachers can apply in the actual classroom. We expect that these teaching plans may be applied to actual classes so that Korean culture education may not be limited to the acquisition of knowledge, but be linked to their real life.

The smart paradigm in the modern society is bringing about a rapid smart sensation and there are means of informational communications being developed with the smart technology in various fields. Accordingly, for an effective smart education, it is necessary to create the customized educational contents for the learners, the users of the education. In this study, the contents of smart education are categorized based on the user experiences. As a result of the analysis, the 3 types of UX are found to have a playful influence on the learning concentration and it is also deduced that such concentration of a learner positively affects his or her attitude towards learning. Moreover, by the age and gender groups, there were differences in the preferences for each of the UX type, so that, in result, gave the valid data for designing and applying the suitable UX type for creating contents of smart education for different main target groups.

This paper addresses the question of why prepositions are particularly difficult forEFL learners. The first reason for such difficulty lies in the distinction between seemingly equivalent prepositions such as to and with, as in compared to and compared with. Most monolingual learners' dictionaries regard these two phrases as virtually synonymous. Yet, the results of the corpus analysis conducted in this study indicate that there are differences between the two. A second reason why EFL learners have problems with prepositions is that there are often variations in the inputdata. For example, although from generally follows different, in American English different than is also used. On the other hand, in British English, different to is the second most commonly used construction. This type of regional variation, confirmed in the corpus findings of the present paper, causes confusion in students of English. A learner who is not accustomed to British English may be puzzled by the expression different to. Finally, L1 negative transfer is responsible for the incorrect use of expressions such as discuss about. An error of this sort is the result of interference from the learner's mother tongue. The English verb discuss is not subcategorized for a preposition, whereas the equivalent Korean verb, for example, requires a noun phrase combined with the postposition.

Evaluation as learning is important for the learner competency test, and the applicable method is studied. Assessment is the role of diagnosing the current learner's status and facilitating learning through appropriate feedback. The system is insufficient to enable process-oriented evaluation in small educational institute. Focusing on becoming familiar with the AI through experience can end up simply learning how to use the tools or just playing with them rather than achieving ultimate goals of AI education. In a previous study, the experience way of AI education with PLAY model was proposed, but the assessment stage is insufficient. In this paper, we propose ELAS (Experiential K-12 AI education Learning Assessment System) for small educational institute. In order to apply the Assessment factor in in this system, the AI-factor is selected by researching the goals of the current SW education and AI education. The proposed system consists of 4 modules as Assessment-factor agent, Self-assessment agent, Question-bank agent and Assessment -analysis agent. Self-assessment learning is a powerful mechanism for improving learning for students. ELAS is extended with the experiential way of AI education model of previous study, and the teacher designs the assessment through the ELAS system. ELAS enables teachers of small institutes to automate analysis and manage data accumulation following their learning purpose. With this, it is possible to adjust the learning difficulty in curriculum design to make better for your purpose.

This study was conducted with students who participated in an online extracurricular after COVID-19 in order to analyze the effects of college students' learning strategy, learning attitude, and achievement motivation on satisfaction. After participating in the online extracurricular, an online survey was conducted, and responses from 163 students were collected. Based on the collected data, the study results were analyzed. The results of the study are as follows. First, learning strategy was found to have a positive effect on satisfaction. These results can be inferred that positive recognition worked in the process of actually applying the learning strategies acquired through the extracurricular to their own learning. Second, learning attitude had a positive effect on satisfaction. The learner's learning attitude to develop necessary skills through experience and the sense of achievement experienced in the process of participating in the online extracurricular had a positive effect on satisfaction. Third, achievement motivation was found to have a positive effect on satisfaction. It can be inferred that the learner's active behavior by participating in the program acts as a motivation for achievement and affects satisfaction. Finally, through this study, a plan for effectively operating extracurricular in an online environment was presented.

The purpose of the ensemble methods is to increase the accuracy of prediction through combining many classifiers. According to recent studies, it is proved that random forests and forward stagewise regression have good accuracies in classification problems. However they have great prediction error in separation boundary points because they used decision tree as a base learner. In this study, we use the kernel ridge regression instead of the decision trees in random forests and boosting. The usefulness of our proposed ensemble methods was shown by the simulation results of the prostate cancer and the Boston housing data.
