An integrated curriculum is an educational approach that combines multiple subjects into a cohesive learning experience. Instead of teaching subjects like math, science, and language arts separately, teachers design lessons that connect these areas, helping students see the relationships between different fields of knowledge. This method encourages deeper understanding and retention of information. By using real-world themes or projects, an integrated curriculum promotes critical thinking and problem-solving skills. For example, a project on environmental science might incorporate geography to study ecosystems and math to analyze data. This holistic approach makes learning more relevant and engaging for students.
