Weighting the Source Analysis in a School Assessment Task
A Year 12 Modern History teacher has designed a school assessment task worth 20% of the subject grade. The task asks students to analyse six primary sources on the causes of World War I and write a 1000-word essay. The draft marking rubric allocates: 60% to factual accuracy about the July Crisis, 25% to source evaluation (origin, purpose, reliability), and 15% to written expression. The faculty moderator notes that the SACE performance standards for Modern History emphasise knowledge and understanding, application of historical skills, and analysis and evaluation, and that the external examination gives substantial weight to source analysis and argument. The teacher has one class of 24 students, including four who receive modified task conditions for verified learning difficulties, and the task must be completed within three 50-minute lessons plus homework. The teacher wants the task to prepare students for the external exam without overloading them.
1. Evaluate whether the draft rubric's weighting is appropriate for a school assessment task that prepares students for the external examination. Justify your judgement with reference to the balance of skills the rubric rewards.
Read the worked answer
The draft rubric is not well balanced for an assessment intended to prepare students for the external examination.
Reasoning:
- 60% for factual accuracy about the July Crisis rewards recall of dates, names, and sequence. This is necessary but is the lowest-order demand and is already heavily tested in the external exam through multiple-choice and short-answer items. Allocating the majority of marks here means a student with strong memorisation but weak analysis can score highly.
- Only 25% for source evaluation is too low given that source analysis and evaluation of origin, purpose, and reliability are central to the external exam's extended responses. The task's own design (six primary sources) signals that source skills should be a major component.
- 15% for written expression is defensible but should be folded into a broader 'communication and argument' criterion rather than isolated.
Recommended reweighting: approximately 30% knowledge and understanding, 40% analysis and evaluation (including source evaluation and argument), 20% application of historical skills (using sources as evidence), and 10% communication.
Caveat: the rubric must still map explicitly to the SACE performance standards, and the teacher should confirm the weighting with the faculty moderator before publication.
2. The teacher must accommodate four students with modified task conditions. Explain how the assessment design should be adjusted so that modifications do not compromise the validity of the task or the comparability of results.
Read the worked answer
Modifications should change access, not demand. The assessed skills and standards must remain the same so results stay comparable.
Appropriate adjustments:
- Extra time (e.g., 25% additional time) or a reduced word count with the same analytical requirements, so the student is not penalised for processing speed or expression difficulties.
- Scaffolded source-analysis template (a structured table for origin, purpose, reliability, usefulness) provided to the four students, while the analytical judgement remains theirs.
- Separate room or rest breaks to manage anxiety or attention needs.
- Use of a scribe or laptop where writing is the barrier, not historical thinking.
What must NOT change: the number or complexity of sources, the requirement to evaluate reliability, or the standard against which analysis is judged. If the task is shortened for some students, the marking rubric must still assess the same criteria at the same standard.
Documentation: each adjustment should be recorded against the student's verified condition and reviewed by the moderator to confirm that the modified task still generates evidence against the same performance standards. This preserves both validity and fairness.
3. Identify the main risk in having students complete the task across three lessons plus homework, and propose a design change that reduces that risk.
Read the worked answer
The main risk is unequal access to time and support outside class, which threatens the validity and fairness of a task worth 20%.
Why it matters:
- Homework completion depends on home environment, internet access, caregiving responsibilities, and private tutoring. Students with fewer resources may produce weaker work for reasons unrelated to historical skill.
- Splitting the task across three lessons plus homework also makes it hard to verify authorship, raising authenticity concerns.
Design change:
- Convert the task to a supervised in-class assessment across the three lessons, with sources provided at the start and the essay written under supervision. This equalises conditions and strengthens authenticity.
- If homework must be retained, restrict it to planning only (e.g., an annotated source table checked in class) and have the essay itself written in class.
- Provide the six sources as a common resource pack so no student is advantaged by access to extra material.
This keeps the task manageable within the available time while ensuring that the evidence produced reflects the student's own historical skills.
