A fourth study of the impact of classroom assessment practices on students and their learning in the context of the classroom was undertaken by Bangert-Drowns, Kulik, and Kulik (1991), who investigated the effects of frequent classroom testing.
A hyphen (-) is a punctuation mark used to join the separate parts of a compound word. A hyphen is a joiner. A hyphen is used to join the words of a compound adjective (e.g., five-page document), to join the words of compound noun (e.g., cooking-oil), and to join a prefix to a word (e.g., re-examine).
This, in turn, comes from hypo âunderâ + hen âoneâ. The hyphen is not the only punctuation mark that signifies togetherness; the plus symbol (+) has also been referred to as a hyphen on rare occasions, as has a short pause between two syllables in speaking and, more broadly, any small connecting link.
