Creating a science assessment for the International Baccalaureate (IB) Diploma Programme is only half the battle. The real time sink is writing the detailed mark scheme.
Why IB Mark Schemes Are Crucial
In the IB DP Chemistry and Physics syllabi, mark schemes are highly structured. They aren't just lists of numbers; they are rubrics that reward specific logical steps. A single question might assign separate marks for identifying a formula, substituting values, using correct state symbols, and writing the final value with appropriate significant figures.
When teachers write tests, compiling these criteria manually takes an enormous amount of effort. If a question is slightly modified, the entire calculation chain must be updated.
Grading Secret
“When grading Chemistry Paper 2, remember that students are awarded marks for showing their work even if a previous calculation was wrong (Error Carried Forward - ECF). Your marking keys must clearly map these steps so that you can grade fairly.”
Generating Compliant Mark Schemes
Imtihan's built-in IB mark scheme generator automates this workflow. When you prompt the AI to generate a question, the platform simultaneously builds a matching correction grid.
The system recognizes key IB Command Terms (e.g., Deduce, Outline, Explain, Annotate) and allocates marks accordingly. For quantitative problems in Physics (like mechanics or quantum fields), the generator produces full calculations in LaTeX format, documenting every step from raw formula to final uncertainty bounds.
Get Started for Free
IB teachers can sign up on Imtihan and generate their first mock exam and mark scheme completely for free. After generation, you can edit individual questions, add custom prompts, and export the entire test and grading key to Microsoft Word or PDF for easy grading.
