In this paper, we aim to develop teaching and learning materials for coding and mathematics convergence classes using Python in middle school. We suggest teaching and learning materials based on computational thinking (CT) using the basic terminology of Python. Many middle school students are familiar with block coding instead of text coding. We provide teaching resources for Basic1, Basic2, and Advanced classes, considering this circumstance. The Basic1 and Basic2 teaching resources contain the basic grammar of Python with simple examples. The Advanced teaching resources are more focused on complicated mathematics and coding problems. We apply these teaching and learning materials to middle school students. The results indicate that this project can be positively applied to learners.

If we followed to be based on the result of survey for researching on the actual condition about e-Learning of the MOE(2004), the critical problem has been suggested managing the quality of teaching and learning materials(37.68%(1775/4717)). If we also reviewed the research of the KICE(2002), the superior material's rate of 70,000 teaching and learning materials of the web site, the educational organization, and teachers was 8.7%. There was some suggestions about the quality problem of the teaching and learning material, but there wasn't the alternative policy: there wasn't the systemic program for managing the message quality of teaching and learning materials. The purpose of this study was to develop the alternative system for managing the message quality of teaching and learning materials. The alternative system of this study's result will be the basic to build the system for managing the message quality of teaching and learning materials. I expect that my system will be the useful tool for managing the message quality of teaching and learning materials.

Even though many researchers have reported that everyday contexts can arouse students' interests and improve their science learning, the connection between everyday context and physics learning is not yet clearly discussed. In our study, at first, we assumed five guidelines for helping the development of teaching materials for physics learning in everyday context. Based on these guidelines, we developed teaching materials for understanding basic optics and applied these materials to ninth grade students. From the positive responses of students and science teachers about the developed materials, we could confirm that the guidelines were reflected well in the materials. And also, it was found that students and teachers wanted to learn or teach context-based physics in future classroom learning. However, all students do not receive benefits from learning physics in everyday context. By analyzing students' actual learning processes and interviews with them, we found five potential impeding factors which could hinder students' successful learning of physics in everyday context. As a result, we suggested five recommendations for overcoming these impeding factors.

This study aims to develop AI mathematics teaching and learning materials for high school students using interactive AI (ChatGPT). The selected topics include text representation, classification, and prediction related to natural language processing, which are key contents of the 'AI Mathematics' curriculum. Python programming language and ChatGPT are employed as educational tools, with Python being accessible through Google Colab. The developed teaching and learning materials are structured into six block sessions, designed to leverage ChatGPT's language proficiency, information provision, creativity, and programming capabilities. Specifically, students sequentially experience code inspection, improvement, explanation, and generation using ChatGPT's programming abilities, culminating in creating their own chatbot program code. The application of these teaching and learning materials resulted in the participating high school sophomores understanding the principles of chatbots using natural language processing and the mathematical aspects within AI technology. The students exhibited positive responses toward using ChatGPT and Python. This suggests that classes utilizing ChatGPT can enhance students' interest and engagement in AI technology, mathematics, and related tools.
