The aim of this study is to design Spudsville, an immersive game environment in Minecraft that can effectively help learners acquire the English language. To create a successful learning experience using Minecraft, the researchers adopted the Agile Model and the Design Thinking approach. The researchers first conducted an analysis through an extensive literature review in order to assess the learners' needs. Afterwards, they designed and developed a Minecraft world based on the data collected during the analysis phase. The researchers learned that implementing constructivist and behaviorist approaches has benefits, even though applying a cognitivist-learning model to Spudsville could have provided the researchers with more insight on how learner processes information. Making these adjustments could improve Spudsville's effectiveness and could potentially help the ways in which gamified learning aids with language acquisition.

The purpose of this study is to develop a 'Competency Model for Beginning Teachers in Home Economics'. The study was conducted in a total of 4 stages(preparation of competency model development stage, materialization stage, validity verification stage, and competency diagnosis stage), and the results of the study were as follows. First, the first tentative competency model was derived through the literature study, and the secondary tentative competency model was derived through an FGI. The validity of the secondary tentative competency model was verified by 15 experts and the competency groups, competencies, and competency definitions from this study were found to have content validity. Second, the competency diagnosis was conducted for a total of 222 beginning teachers in Home Economics. As a result, a total of 7 competencies were derived as the 'top priority competencies' that are of first priority for beginner teachers in Home Economics. The final competency model which was developed by reflecting the research results, was composed of 4 competency groups and 22 competencies and 22 competency definitions. The competencies of each competency group were presented in the order that beginning teachers thought were important. This study is meaningful in that it used an FGI and competency diagnosis to identify beginning teachers' perceptions and demands of the competencies and reflect the results on the competency model development.

This study is to find out the possibility of applying the Blended Learning which combines the advantage of face-to-face classroom instruction and e-Learning to design education. This Blended Loaming Model has five steps such as 'prepare, teach, show, interact, and collaborate'. It is designed by the learning decision points (performance outcomes, content stability and structure, audience size, and so on) and the characteristics of delivery methods(asynchronous, synchronous). This research is based on the learners' satisfaction data of each step. The number of the participants is 27 and a questionnaire with 21 items is administered. Ten items of them are designed with 5-point Likert scales and the rest of them ask learners describe the reason of their selection. The result show that learners are satisfied with the blended learning than the off-line classroom. It is expected that the blended learning can be a substitute of the off-line classroom for the effectiveness of design education.

As smart education increases the demand for new teaching-learning methods, teacher training colleges need to systematize smart education teaching-learning methods for pre-service teachers. This study designed a smart education teaching-learning model, which is applicable to pre-service teachers, by analyzing the smart education teaching-learning types for primary and secondary schools at national and international levels and by analyzing the Creation Teaching Learning Assessment (CTLA) model. The goal of smart education is to reinforce capability of learners. The smart education teaching-learning model designed to help pre-service teachers reinforce their smart literacy is suitable for reinforcing capability of future learners to receive smart education. The smart education teaching-learning model in this study was designed as a 15-week teaching plan applicable to pre-service teachers at teacher training colleges. In the teaching-learning model, problem-based learning (PBL), a situated learning model, and cooperative learning model were applied to weekly instructions. Further research should be conducted to prove its effectiveness in allowing pre-service teachers to reinforce their smart literacy by making gradual improvement in this model and to develop and test smart education teaching-learning models constantly.

The purpose of this study is to probe secondary science teachers' perception on scientific models and modeling. A total of 50 experienced science teachers were surveyed with 10 open-ended questions about several aspects of models and modeling: definition, examples, purpose, multiplicity, changeability, design/construction, evaluation and beliefs in the use of models and modeling as a teaching tool. The analysis of the data shows the following results: 1) understanding of models and modeling held by a majority of experienced secondary science teachers was far from that of experts as they concentrated on a model's superficial, representative, and visual functions, 2) when it comes to their view toward the use of a model, a model does not remain in the stage of 'doing science' but in the stage of being a subsidiary teaching tool for the teacher's explaining and the students' understanding of scientific concepts, 3) the subjects they majored in made meaningful differences in their contextual understanding of models and modeling, 4) though most of the teachers acknowledged the importance of teaching about models and modeling, even a lot of them showed a negative position toward the opinion that they are willing to apply modeling to their classes. Implications of the results were discussed in terms of intervention in order to enhance secondary science teachers' understanding and pedagogical content knowledge of models and modeling.
