This study analyzed the contents of "Reading" textbooks for 1st-6th grades. The focus of the analysis was on philosophical thinking methods designed to help children to think for themselves. Following the analysis, methods were designed for the application of effective use of Philosophy in the elementary school curriculum. Analysis of works of children's literature in "reading" textbooks show patterns of logical, ethical and creative thinking. Therefore, "reading" textbooks can be used to help children to think philosophically. Five stages of discussion can be applied in the classroom; these are: establish the issues, outline the process of discussion, discuss the issues, evaluate and summarize the discussion, apply the learning to other subjects. Teachers can use philosophical thinking methods to improve the quality and quantity of instruction with various questions, having children express their opinions, interpreting their thoughts clearly, maintaining logical consistency, and evaluating the procedures and results of discussion. These methods can be used in the teaching-learning process in the elementary school to develop rich findings and meaningful communication.

Grammar has long been regarded as an important element in foreign language learning and has received a lot of attention from foreign language learners and researchers. However, in the process of learning, learners will confront an increasing number of words some of which may have multiple meanings. It is not easy for language learners to memorize and master the correct use of these words, especially in terms of pragmatics. Some learners may use the grammar correctly, but their writing or utterance may feel unnatural in discourse. In Korean, '나다, 들다' are two basic verbs, but they have many different meanings which cause a lot of confusion among learners of Korean as a foreign language. In this article, the writer attempts to make a distinction between the collocations of the two verbs '나다, 들다' and provides an effective method for teaching the learners of Korean in China.

Purpose: The purpose of this study was to verify the educational effectiveness of the Objective structured clinical examination (OSCE) module development activities on nursing students in the areas of performance skill, knowledge, self-directed learning readiness, and problem solving ability for medication skill. Methods: This study was a nonequivalent control group non-synchronized post-test design. The subjects (N=47), who agreed to participate in this study, were assigned to either the experimental (n=24) or control group (n=23). The experimental group was trained with OSCE module development activities for four days. The control group was trained with a traditional demonstration and practice class for the same amount of time as the experimental group. Medication performance skill and knowledge tests and surveys were done to measure self-directed learning readiness, and learning satisfaction after the experimental treatments. Results: The experimental group which participated in the OSCE module development activities showed significantly higher performance skill, self-directed learning readiness, and problem solving ability for skin test and insulin medication than that of the control group of traditional education. Conclusion: It is recommended to use the OSCE module development activities for nursing students in nursing education-learning in order to improve nursing skills.

Education has recently witnessed a rapid increase in the use of edutech worldwide. This study focuses on Korean workers and explores an edutech-based learning model for vocational education and training. Based on analyses of edutech cases and interviews with edutech experts, a draft edutech model was designed and the validity was evaluated based on two Delphi surveys with a panel of experts in the field. The study's findings suggest that edutech-based employee education and training should prioritize LXP orientation (last CVR=1, last Mean=4.70) , implement adaptive learning through learning analytics (last CVR=1, last Mean=4.90), enhance the human touch effect using edutech (last CVR=1, last Mean=4.90), and emphasize the importance of designing curricula that apply edutech in a step-by-step learning process while incorporating suitable instructional design for the key technologies involved in vocational training programs. In addition, it was revealed that there is a strong need to implement a method that makes each stage of the learning process more effective (before, during, and after). Edutech-based vocational training program should consider the interests of all stakeholders, including learners, instructors, vocational training institutions, and government agencies. Given the promotion of government-sponsored vocational training projects in Korea, the findings of this research are likely to have significant implications for the future of Korea's education and training policies.

Big data issue has been considered in diverse fields. Also, big data learning has been required in all areas such as engineering and social science. Statistics and machine learning algorithms are representative tools for big data learning. In this paper, we study learning tools for big data and propose an efficient methodology for big data learning via legacy data to practical application. We apply our big data learning to patent analysis, because patent is one of big data. Also, we use patent analysis result for technology forecasting. To illustrate how the proposed methodology could be applied in real domain, we will retrieve patents related to big data from patent databases in the world. Using searched patent data, we perform a case study by text mining preprocessing and multiple linear regression of statistics.

Project-based learning (PBL) encourages self-autonomy and connects learning and real-life skills in the learning process. The purpose of the current study is to investigate students' life skills and self-regulated learning strategies in a PBL curriculum in order to examine how the proposed benefits of PBL are manifested in students' self-awareness of their learning process. Twenty-three students in a university in Korea participated in a 3-credit, 4-week, intensive PBL course for English majors. During the PBL course, students were asked to self-assess their life skills related to time management, cooperation, standard of work, and participation three times. In addition to the self-assessment, students kept reflection journals to keep track of their use of self-regulated learning strategies and progress which were also submitted three times. Based on the analysis of self-assessment and self-reflection, the results showed that students' perception of cooperation improved significantly during PBL. Furthermore, it was found that students also progressed through the three phases of self-regulated learning. Implications on suggesting on the use of PBL to encourage the development of life skills and self-regulated learning strategies are provided.

The purpose of this study was to construct land cover maps using a deep learning model and to select the optimal deep learning model for land cover classification by adjusting the dataset such as input image size and Stride application. Two types of deep learning models, the U-net model and the DeeplabV3+ model with an Encoder-Decoder network, were utilized. Also, the combination of the two deep learning models, which is an Ensemble model, was used in this study. The dataset utilized RapidEye satellite images as input images and the label images used Raster images based on the six categories of the land use of Intergovernmental Panel on Climate Change as true value. This study focused on the problem of the quality improvement of the dataset to enhance the accuracy of deep learning model and constructed twelve land cover maps using the combination of three deep learning models (U-net, DeeplabV3+, and Ensemble), two input image sizes (64 × 64 pixel and 256 × 256 pixel), and two Stride application rates (50% and 100%). The evaluation of the accuracy of the label images and the deep learning-based land cover maps showed that the U-net and DeeplabV3+ models had high accuracy, with overall accuracy values of approximately 87.9% and 89.8%, and kappa coefficients of over 72%. In addition, applying the Ensemble and Stride to the deep learning models resulted in a maximum increase of approximately 3% in accuracy and an improvement in the issue of boundary inconsistency, which is a problem associated with Semantic Segmentation based deep learning models.

In the near future, we can access the information whenever we want, wherever we use because almost devices in ubiquitous environment are connected by either wired or wirelss networks. Especially, u-Learning which emphasizes on pedagogical property is enable to improve learning abilities. As researches of the previous u-Learning, there have been learning by mobile devices such as PDAs as well as the smart classroom which makes the remote students participate in the existing class. However, these researches have not satisfied pedagogical, cooperative and ubiquitous properties yet. Thus we suggest the framework for both local and mobile classroom, which can make the properties easy to satisfy.

It is examined that how flipped learning and mind-wandering affect an idea generation task. For the purpose, the participants in the idea generation task are divided into two groups to learn SIT(Systematic Inventive Thinking) and BCC(Business Creativity Codes) as idea generating tools in advance. One group learned the tools in a classroom, and the other group through an online education program. The creativity level of an idea is evaluated in the dimensions of originality, practicality, and realizability. The creativity levels of the ideas from the two groups are not statistically different in all the three creativity dimensions. To examine the effect of mind-wandering, another group generated ideas two hours a day in four days instead of eight hours in one day. The creativity levels of the ideas from the third group are higher in the dimensions of originality and practicality. This shows that the effectiveness of flipped learning is not so different from the face-to-face learning in a classroom, and mind-wandering has a positive effect in the learning.

The on-line and mobile communication technologies provide an environment to make users share information on the rove. However learning on a file received from on-line or mobile internet environment is able to read only, According to this, users cannot use various learning methods to make multimedia contents for learning like coloring and underlining considerable parts. Also, in case of storing, it cannot be stored in a standard file format HTML. Therefore, in this paper, we suggest a new learning platform to be able to change text contents in a web documents and implement a prototype system to process learning system in on-line environment
