Schools are funded by the provincial government and local property taxes. The province's 75 school districts are administered by locally elected boards.

The comma is the most important punctuation mark after the full stop. Its main use is for separating parts of sentences. Commas function in five main ways:
1. Before or after adverbial clauses and groups.
2. Before various connectives to join two independent clauses.
3. To separate some non-defining phrases from the rest of the sentence.
4. To separate words, groups and clauses in a series.
5. To separate adjectives that separately modify the same noun.

The apostrophe has two main functions in English, but only one in academic writing. It is used mainly to show possession or relationship. It is also used in informal writing to show contraction or letters left out.
The apostrophe precedes the 's' in singular words and plurals that do not end in 's'. It follows the 's' in plurals that end in 's'. The apostrophe is not used with the possessive pronouns 'hers', 'yours', 'theirs' and 'its'.

In academic writing, quotation marks are used to show that you are quoting directly from another author's work. The quotation marks should enclose the actual words of the author and all bibliographical information must be given.
Hillocks (1986) similarly reviews dozens of research findings. He writes, "The available research suggests that teaching by written comment on compositions is generally ineffective" (p. 167).

He stated, "The 'placebo effect,' ... disappeared when behaviours were studied in this manner" (Smith, 1982, p. 276), but he did not clarify which behaviours were studied.
