Assessment Evidence Conference

Overview

Lesson 6 consolidates the unit Interpret Statistical Information and prepares students for the internal assessment. Students independently refine a response that interprets statistical information for a stated purpose, selecting accurate, relevant and contextualised evidence before checking their readiness against current assessment requirements.

Learning intentions

Students will:

• interpret tables, graphs and statistical summaries for a specific purpose and context
• select relevant numerical and visual evidence to support claims
• evaluate the strength, limitations and appropriateness of statistical information
• communicate a clear conclusion justified by evidence
• apply assessment, authenticity and submission procedures responsibly

Success criteria

I can:

• identify the purpose, context and population relevant to a report
• accurately describe patterns, trends, distributions and comparisons
• use appropriate measures and denominators, linking evidence to the purpose
• identify limitations, evaluate claims and communicate a justified conclusion

Curriculum links

• Evaluate a statistically based report by commenting on survey features, findings, errors, sample size and purpose.
• Use statistical methods to make an inference by interpreting displays, sample statistics, variability and context.
• Apply the statistical enquiry cycle: interpret evidence, evaluate processes and communicate conclusions.
• New Zealand Curriculum key competencies: thinking; using language, symbols and texts; managing self; relating to others.

Lesson structure (60 minutes)

1. 0–10 min · Retrieval quiz. Teacher opens with the retrieval quiz and assessment focus and distributes the evidence review and readiness worksheet. Students complete a short individual quiz covering population, sample, variable, distribution, centre, spread, trend, association, sampling error, non-sampling error, relative frequency, denominator, claim and limitation. Review answers briefly, asking students to correct one common error in a different colour.

2. 10–25 min · Peer evidence review. Teacher displays the peer-review protocol and models one example: a claim is only useful when the evidence is accurate, relevant to the stated purpose and explained in context. Students exchange drafts with a partner and use the worksheet checklist: accuracy, relevance, context, evidence, justification, limitations and communication. Reviewers write one specific strength, one unsupported or unclear claim, and one actionable improvement. Writers ask clarifying questions but retain responsibility for all revisions.

3. 25–45 min · Individual revision or timed practice. Teacher explains that students may revise their own draft or complete a timed practice section using the approved task materials. Students work independently, improving weak paragraphs or answering a selected section under assessment-like conditions. They must check that comparisons use appropriate denominators and relevant measures, claims are supported by numerical or graphical evidence, limitations are identified, and the conclusion answers the purpose rather than merely repeating results. Teacher circulates for process questions, not content editing.

4. 45–55 min · Teacher evidence conference. Teacher meets briefly with students individually or in pairs, using the checklist in the evidence conference and readiness slides. Students identify their strongest evidence and one remaining risk. Teacher checks that the learner’s work is their own under the organisation’s authenticity procedure, confirms the current outcome and evidence requirements, and checks that every required component is present. Feedback is recorded consistently against the approved schedule; the teacher judges accuracy and context, not decoration.

5. 55–60 min · Readiness reflection. Teacher displays the final reflection prompts. Students complete the last section of the evidence review and readiness worksheet: “My response answers the purpose because…”, “My best supporting evidence is…”, “One limitation I have addressed is…”, and “Before submission I must…”. Students rate their readiness from 1–5 and name one concrete next step.

6. Throughout · Assessment administration reminders. Teacher reinforces that supervised or documented checkpoints, planning and drafts must be retained where required; permitted tools and sources must be declared; and assistance must comply with policy. Students record any procedural question for follow-up rather than making assumptions about resubmission, storage, reporting or appeals.

Resources

• assessment readiness and evidence conference deck
• evidence review and readiness worksheet
• Current NZQA US 26626 and approved assessment task
• Approved assessment schedule and teacher evidence checklist
• Moderation materials and authenticity documentation
• Calculators and students’ drafts
• Digital display or projector

Assessment

• Use the retrieval quiz to identify misconceptions about statistical vocabulary, comparisons, evidence and common errors.
• Monitor peer-review comments and individual revisions for accurate interpretation, contextualised evidence and justified claims.
• Collect or photograph the final readiness reflection and record conference feedback consistently. Apply the current assessment procedure for authenticity, reassessment, resubmission, appeals, moderation, storage and reporting; resubmission is only offered when permitted and only for incomplete or insufficient evidence.

Differentiation

• Provide sentence starters on the worksheet: “The purpose is…”, “The graph shows…”, “This suggests… because…”, “A limitation is…”, and “Therefore, the claim is…”.
• Allow students to annotate a printed or digital copy of their draft and use a quiet, supervised workspace during the individual revision period.
• Confer first with students who have incomplete evidence, difficulty distinguishing description from interpretation, or uncertainty about denominators and contextual language.
• Extend confident students by asking them to consider an alternative explanation, the effect of sampling variability, or whether a different measure or display would better answer the purpose. Support EAL learners with a vocabulary bank and paired verbal rehearsal before writing.
