The Grade 11 IB Physics HL/SL rubric provides a structured framework for assessing student performance across key learning objectives in the International Baccalaureate program. This rubric evaluates students on their understanding of core physics concepts; application of scientific principles; and ability to analyze and solve complex problems. It emphasizes critical thinking; experimental skills; and effective communication of scientific ideas; preparing students for higher education and STEM-related careers. The rubric assesses knowledge and comprehension through questions that test fundamental theories; laws; and terminology in mechanics; thermodynamics; waves; and electricity. Students must demonstrate accuracy and depth in their responses. Application and analysis are evaluated through problem-solving tasks; requiring students to apply physics principles to real-world scenarios and interpret data from experiments. Higher-level students (HL) engage with more advanced topics; such as quantum physics and relativity; while standard-level (SL) students focus on essential concepts. Inquiry and experimental skills are a key component; with students assessed on their ability to design; conduct; and evaluate investigations. The rubric measures precision in data collection; error analysis; and logical conclusions; fostering a strong foundation in scientific methodology. Communication is also evaluated; ensuring students can present arguments clearly using appropriate terminology; graphs; and mathematical representations. By aligning with IB standards; this rubric encourages holistic learning; integrating theory with practical skills. It supports differentiated instruction; allowing teachers to identify strengths and areas for improvement. Students benefit from clear expectations; enabling them to track progress and develop a deeper appreciation for physics. Ultimately; the rubric cultivates analytical; collaborative; and independent learners ready for academic and professional challenges.
