Teacher's Guide

Learning objectives

• Explain  资    料    zīliào and  修    改    xiūgǎi in the context of this lesson.
• Use the worked example to answer the three practice questions with supporting reasoning.
• Complete the activity, evaluate its result, and identify one limitation or possible improvement.

Prerequisites: The preceding grade sequence or equivalent introductory knowledge; begin with a short vocabulary review.

Suggested time: Three to five 45-minute sessions, including activity development and review. Language units need brief repeated spoken practice between sessions.

Teaching sequence

1. Introduce: Present the title as a question or problem. Ask learners what they notice and record two initial ideas without treating them as established facts.
2. Explain: Read the concept section and teach the two vocabulary items. Ask learners to paraphrase the distinction between them using a concrete example.
3. Model: Work through the example. Identify given information, assumptions, and the reason for the result or interpretation. Use a teacher's spoken model for language pronunciation.
4. Apply: Complete the activity individually or in pairs. Require a draft, a check against the task, and a brief revision. Discuss why different justified responses may be acceptable.
5. Retrieve and evaluate: Answer practice and vocabulary questions independently; use the answer key for feedback. Finish with the reflection and an activity rubric.

Assessment and differentiation

The companion CSV contains five retrieval entries: two vocabulary questions and three practice questions. Award one point per accurate answer, accepting equivalent wording that preserves the meaning. Language answers may be oral or written according to the goal. Revisit missed concepts rather than using the score as the only measure of learning.

Assess the activity separately with four criteria, each scored 0-2: correct use of lesson concepts; clear evidence or reasoning; completion of the task requirements; and a useful revision or acknowledged limitation. A 0 indicates missing or unsupported work, 1 indicates partial achievement, and 2 indicates clear achievement. Accept multiple designs, interpretations, and decisions when their reasons meet the criteria.

Support learners with a word bank, annotated example, smaller first step, or partner rehearsal. Extend by changing one assumption or constraint and asking how the result would change. Use invented personal details in financial and social tasks. Optional school character discussion can connect honesty, respect, cooperation, and stewardship to the activity; assess the subject knowledge and reasoning separately.

Student Worksheet

Concept and helping material

A language portfolio combines selected writing, spoken work, source records, and revisions. A research presentation distinguishes sourced information from opinion and inference. Scope should match language proficiency, with familiar forms used accurately before added complexity. Assess communication, evidence, organization, and revision separately.

Vocabulary

•  资    料    zīliào: Information or reference material.
•  修    改    xiūgǎi: To revise or modify.

Worked example

A learner presents a fictional school reading survey, clearly labeling it as classroom data.  我    们    采    访    了    五    位    学    生    (Wǒmen cǎifǎng le wǔ wèi xuésheng) states We interviewed five students, not the whole school.

Investigation or design task

Prepare a three-minute Mandarin presentation about a teacher-approved classroom topic. Submit a script, attributed sources or fictional-data labels, and two revised writing samples.

Record your work: State the goal; show your drawing, dialogue, calculation, data, or argument; explain one choice; and describe one check or revision. Identify a limitation rather than claiming your work proves more than it does.

Practice

1. How many students were interviewed in the example?
2. Does that number justify a claim about the whole school?
3. What should a portfolio show beyond final products?

Vocabulary retrieval

1. Define  资    料    zīliào.
2. Define  修    改    xiūgǎi.

Reflection

Choose one answer or activity decision. Explain the evidence, calculation, language pattern, or reasoning that supports it. Describe one change of context or assumption that could change your conclusion.

Answer Key

1. Five.
2. No.
3. Evidence of decisions, feedback, and revision.

Vocabulary answers are the definitions above and appear in the CSV. Activity and reflection responses vary; use the teacher rubric and require specific reasoning tied to the task. A different supported interpretation is acceptable where the question allows it.

Source Reference

Original teaching material. No directly matching, age-appropriate lesson reference was identified in the supplied G7-12 PDF collection. No external research is claimed.
