Supplied materials

  • For younger learners, an adult may read each direction aloud; pointing, drawing and spoken explanations count as responses.
  • Paper, drawing space or a browser document.
  • Reference card A: reader gives the intended message. Reference card B: reader gives another message.
  • Assessment case 1: Which scientific label fits the specifically described step or feature? Supplied case: STOP sign is read as stop.
  • Assessment case 2: Which scientific label fits the specifically described step or feature? Supplied case: STOP sign is read as go.
  • Assessment case 3: Which scientific label fits the specifically described step or feature? Supplied case: Sign is drawn but no response logged.
  • Assessment case 4: Which scientific label fits the specifically described step or feature? Supplied case: Larger sign gets another reader check.
  • Assessment case 5: Which scientific label fits the specifically described step or feature? Supplied case: HELP sign is read as help.
  • Assessment case 6: Which scientific label fits the specifically described step or feature? Supplied case: WAIT sign is read as stop.

Learn the idea

A better-looking sign does not necessarily communicate better. In the supplied fictional trials, check correct interpretation and note which design was used.

Correct means reader gives the intended message. Incorrect means reader gives another message. Missing means no reader result supplied. Retest means changed design checked again.

For correct, look for the clue “reader gives the intended message.” For incorrect, look for “reader gives another message.” More than one process can happen in a real situation. Answer about the one described in this question.

  1. Read or listen to the four science words and what each means. Say how the first two differ.
  2. Choose two of the short cases. Point to the clue that helps you choose a science word for each one. You may draw or say your answer.
  3. Answer each practice question. Say which clue helped you, then check the explanation.
  4. Use the extra task to make two examples that show different science words. Draw or say what makes each one fit.
Worked example

See the method in action

Worked reference-card problem: a card states “reader gives the intended message”; a second states “reader gives another message.” The first fits correct and the second fits incorrect. The reason is the described function or change, not the order of the cards or a favorite name. If their descriptions exchange places, their category labels exchange too. Keep the supplied descriptions attached to the correct case.

Helpful tips
  • Use the feature “reader gives the intended message” to justify correct; do not sort by the name alone.
  • Distinguish incorrect (reader gives another message) from a different process occurring in the same situation.

See the answer and explanation

correct

The answer is correct. In the notes, it means “reader gives the intended message.” A better-looking sign does not necessarily communicate better. In the supplied fictional trials, check correct interpretation and note which design was used.

Take it further

Create one new case showing correct and one showing incorrect. Expected: the first explicitly shows “reader gives the intended message”; the second explicitly shows “reader gives another message.” Explain the distinction by drawing, speaking or writing. A label without a matching feature is incomplete.

More practice: try new cases

Choose an answer for each problem. Explain your method on paper, then use the feedback to decide what to revisit.

More practice: try new cases
1. Which scientific label fits the specifically described step or feature? Supplied case: STOP sign is read as go.
Need a hint?
  • Look for the described feature: reader gives another message.
  • Compare the clue with each science word. Use only what the case tells you; do not add a new event.
2. Which scientific label fits the specifically described step or feature? Supplied case: Sign is drawn but no response logged.
Need a hint?
  • Look for the described feature: no reader result supplied.
  • Compare the clue with each science word. Use only what the case tells you; do not add a new event.
3. Which scientific label fits the specifically described step or feature? Supplied case: Larger sign gets another reader check.
