Identify a definition strategy

Supplied materials

• Paper and pencil, or a browser text area. All named people/events/records are fictional learning inputs.
• Worked case: Excerpt A: A hinge is a movable joint whose distinguishing feature is permitting connected pieces to turn relative to each other. Excerpt B: The writer compares a one-week adult survey with a one-year all-ages survey as if their percentages represented the same population and period. Excerpt C: Jo attached a paper strip between two panels. On the first bend the crease flexed; on the fifth the paper tore. She replaced the strip and wrote the observed limit beside the model. Following this one model shows what the test record contains. Excerpt D: The proposal says the activity is accessible, but accessible may mean merely online or usable by the specified learner.
• Primary check: Excerpt A: A useful boundary: a page can be online but too small to read; this case does not meet our usable-text definition of access. Excerpt B: Recommendation: print the large-text sheet at home; it never checks whether learners have a printer. Excerpt C: An available page is like an open doorway: both offer entry. But a digital page also needs readable content and a usable response method; the physical doorway analogy cannot prove those are present. Excerpt D: Claim: Jo saw Lea with her card. It is unclear whether her names Jo or Lea as the card’s owner.

Learn the idea

A writer can define by class and features, contrast, examples or an operational rule. Operational definitions specify how a study will count or classify, not necessarily every ordinary meaning.

Use the supplied strategy and explain what it clarifies. Identify any boundary the definition leaves open.

Original worked input: Original excerpt A: A hinge is a movable joint whose distinguishing feature is permitting connected pieces to turn relative to each other. The task is to identify a definition strategy. The answer is “category plus distinguishing features”. Evidence: A hinge is a movable joint whose distinguishing feature is permitting connected pieces to turn relative to each other. Reasoning: category plus distinguishing features is supported because a general category is narrowed by the feature distinguishing this concept. One example alone may not establish all boundaries.

1. Read the supplied worked case and identify the part named in this lesson. An adult can model unfamiliar words.
2. Use the supplied strategy and explain what it clarifies. Identify any boundary the definition leaves open.
3. Check the worked solution: category plus distinguishing features. Evidence: A hinge is a movable joint whose distinguishing feature is permitting connected pieces to turn relative to each other. Reasoning: category plus distinguishing features is supported because a general category is narrowed by the feature distinguishing this concept. One example alone may not establish all boundaries.
4. Use the new primary and practice cases. Give a reason from the actual words before checking the feedback.

Changed-input task: Original excerpt A: For this trial, completion means submitting all four answers and one explanation meeting the visible criteria. Give an evidence-based answer before looking at the model. Expected reasoning: Evidence: For this trial, completion means submitting all four answers and one explanation meeting the visible criteria. Reasoning: operational rule for this study is supported because a stated trial rule tells readers exactly what counts here. One example alone may not establish all boundaries. Then write a brief alternative sentence, paragraph, source note or scene that demonstrates the same operation; label new fictional details and preserve source limits.
