Introduction to the AI Curriculum from Year 7 to Year 13 Artificial Intelligence (AI) is transforming industries, economies, and societies at an unprecedented pace. Understanding AI’s principles and applications is becoming essential for the next generation of innovators, leaders, and informed citizens. This AI curriculum, spanning from Year 7 to Year 13, is designed to equip students with foundational knowledge, practical skills, and ethical awareness in AI. By integrating AI education into school curricula, we aim to foster critical thinking, creativity, and problem-solving abilities among students. The curriculum is structured to provide a progressive learning experience, starting with basic concepts in Year 7 and advancing to specialized AI topics and applications by Year 13. Each year is divided into three terms, focusing on different aspects of AI, including machine learning, data analysis, programming, and real-world applications. Practical projects and collaborative learning are emphasized to ensure students can apply their knowledge in meaningful ways. Year 7-9 (Introduction to AI) Students begin their AI journey with an introduction to AI concepts, basic programming with Python, and exploring AI’s impact on everyday life. They also learn about data and AI ethics, which are crucial for responsible AI development. Year 10-11 (Intermediate AI Studies) Building on the basics, students delve into machine learning, data preprocessing, and visualization. They also explore the ethical implications of AI and advanced programming techniques using libraries like TensorFlow and PyTorch. Collaborative projects prepare them for GCSEs and real-world problem-solving. Year 12-13 (Advanced AI Studies) In the final stages, students engage with advanced AI topics such as deep learning, natural language processing, and AI applications in various sectors. They learn specialized programming and tools, understand big data, and undertake capstone projects that address real-world challenges. Participation in AI competitions and hackathons further enhances their practical experience.

Implementing AI in Education: Enhancing Learning and Administrative Efficiency Artificial Intelligence (AI) has revolutionized the EdTech industry, transforming the way education is delivered and experienced. This transformation is driven by AI’s ability to analyses vast amounts of data and tailor learning experiences to individual needs. Here, we explore how AI impacts EdTech through personalized learning, intelligent tutoring systems, automated grading and feedback, predictive analytics, and enhanced administrative efficiency. We also address the challenges and future prospects of AI in education. Note: This research was conducted using AI; however, the main idea and structure were developed by Mr. Noureddine Tadjerout. Utilizing AI can expedite research and analysis, but the core ideas and research are human-driven. AI is a tool to assist and enhance the research process, not replace human creativity and insight. Table of Contents Introduction • Overview of AI in Education • Importance and Impact of AI Main Responsibilities of an AI Implementation Specialist • Needs Assessment • Solution Design and Selection • Deployment and Integration • Training and Support • Performance Monitoring Real System Implementation in a School • Personalized Learning • Example: Mathematics (Primary and Secondary Levels) • Implementation Details • Intelligent Tutoring Systems • Example: Science (Primary and Secondary Levels) • Implementation Details • Automated Grading and Feedback • Example: English (Secondary Level) • Implementation Details • Predictive Analytics • Example: General Academic Performance (Primary and Secondary Levels) • Implementation Details • Enhanced Administrative Efficiency • Example: Administrative Tasks • Implementation Details AI Applications and Tools for Specific Subjects • Science • Physics • English • Mathematics • ICT/Computer Science • History • Geography • Chemistry • STEAM • Spanish/French Challenges and Considerations • Algorithmic Biases • Data Privacy • Digital Divide Future Prospects • Advancements in AI Technologies • Potential for Bridging Educational Gaps • Promoting Lifelong Learning Conclusion References Note • Acknowledgment of AI and Human Collaboration in Research

Introduction : Introduction to Landscape Modeling Welcome to our project on landscape modeling! Today, we will explore how to create a realistic landscape model using both digital tools like Tinkercad and physical materials. Our goal is to recreate a mountain scene with a bridge and river, similar to the image shown. We’ll start by sketching our ideas, then move on to digital modeling in Tinkercad, and finally, build a physical model. This process will help us understand the principles of landscape design and the practical aspects of constructing a model. Marking Rubric for Project 4 : Landscape
