Mathematics Teaching & Worked-Solution Evaluator

Your work at IXO

Create IXO teaching scenarios that test both mathematical correctness and the quality of the explanation offered to a learner.

Responsibilities

• Write worked solutions with an explicit reason for every significant step.
• Write reference answers explaining the instructional reasoning and relevant evidence.
• Expose misconceptions and answers that are correct only by accident or teach an invalid method.
• Grade generated material against explicit criteria and explain consequential errors.
• Refine the scenario and rubric so another educator can apply the same standard.

Required experience and preparation

A teaching license or certification with a mathematics endorsement, two years of classroom mathematics teaching, and depth from foundational numeracy to advanced coursework. Clear written English and availability for at least ten hours per week are required.

Preferred experience

AP, IB or equivalent courses, mathematics competitions or team advising, curriculum writing or assessment design.

Deliverables and engagement

Deliverables include scenario briefs, reference responses, evaluation criteria and documented model-output reviews. Work is remote and asynchronous; IXO will agree the scope and schedule before assignments begin.

Pay

Pay is $50 • $85/hr in USD. IXO will agree the scope, deliverables and schedule before work begins.
