Peer Editing the Robotics Report: Required Edits versus Optional Changes
Mr. Okafor's Grade 8 students are peer-editing a science report paragraph. The paragraph reads: 'Last spring, the robotics team built a rover, it could collect soil samples. Each of the rover's six wheels have a separate motor. The team tested the rover in a sandbox, and they recorded every failure. Neither the coach nor the students were satisfied with the first design. The rover's solar panels, which had collected dust, was cleaned before the demo. The data was reviewed by the whole team.' Six items are flagged: (1) the comma after 'rover,' (2) 'have' after 'wheels,' (3) 'they' after 'team,' (4) 'were' after 'students,' (5) 'was' after 'panels,' and (6) 'was' after 'data.' Students disagree about which flags are actual errors in standard written English and which are stylistic or acceptable. Mr. Okafor must guide them to distinguish required edits from optional changes.
1. Which of the six flagged items require correction in standard written English? Explain why the other flags are acceptable or optional.

Flags 1, 2, and 5 require correction. Flag 1 is a comma splice: two independent clauses ('the robotics team built a rover' and 'it could collect soil samples') are joined by only a comma. Flag 2 is a subject-verb agreement error because 'each' is singular, so the verb should be 'has,' not 'have.' Flag 5 is also agreement: the subject is 'panels,' which is plural, so the verb should be 'were cleaned,' not 'was cleaned.'
Flags 3, 4, and 6 are acceptable. Flag 3: 'they' can refer to 'the team' when the members act collectively; it is clear enough in context. Flag 4: with 'neither ... nor,' the verb agrees with the nearer subject, 'students,' which is plural, so 'were' is correct. Flag 6: 'data' is often treated as a singular mass noun in standard usage, so 'was' is acceptable; some style guides prefer 'data are,' but consistency matters more than treating this as a required Grade 8 correction.
2. Revise the first sentence in two different ways to fix the comma splice. Explain how the two versions create slightly different effects.

Version 1: 'Last spring, the robotics team built a rover; it could collect soil samples.' The semicolon keeps the two ideas in one sentence and signals that they are closely related, which is appropriate in a report that describes the rover and its function together.
Version 2: 'Last spring, the robotics team built a rover. It could collect soil samples.' The period creates two separate sentences and gives the second idea more independence. It may feel more emphatic or more clipped.
Both versions are grammatically correct. The choice depends on emphasis: the semicolon emphasizes connection, while the period emphasizes separation. Mr. Okafor can use this pair to show that editing is not only about obeying a rule; writers choose punctuation to guide how readers connect ideas.
3. A student insists that 'they' is wrong because 'team' is singular. Write a response that explains why the pronoun is not an error and when a writer might still revise it.
Read the worked answer
The student is applying a rule too rigidly. 'Team' is a collective noun, and collective nouns can take singular or plural verbs and pronouns depending on whether the group is treated as one unit or as a collection of members. In 'The team tested the rover ... and they recorded every failure,' the members are acting together but the pronoun 'they' points to the people doing the recording, so the sentence is acceptable in standard written English. A writer might still revise for clarity, for example by writing 'team members recorded every failure,' but that is a stylistic choice, not a required correction. Mr. Okafor should ask students to distinguish between an actual error and a possible improvement; peer editors should not mark every debatable usage as wrong.
