Your teacher wants you to find examples of each and explain the example you find for each literary term.
For example, when writing about diction, you'd be giving an example of an author's word choice (formal? informal? slang? lots of use of word from foreign language? what?) and then explaining why you think the author chooses those words in the context of what he/she is writing.
If you'll try writing about one or two of the terms you need and re-post, someone here will be happy to comment on your ideas.
When I talk about writing technique, I talk about the authors word choices, writing style ( how sentences are put together), tone.
These are the technical aspects a writer uses to make their point or achieve their purpose in writing.
So, when writing an essay that includes these things, after you have said what the author wants to achieve, then you will show how the author uses these technical aspects to do that.
Here's further information about DICTION, for example:
"DICTION: The choice of a particular word as opposed to others. A writer could call a rock formation by many words--a stone, a boulder, an outcropping, a pile of rocks, a cairn, a mound, or even an "anomalous geological feature." The analytical reader then faces tough questions. Why that particular choice of words? What is the effect of that diction? The word choice a writer makes determines the reader's reaction to the object of description, and contributes to the author's style and tone. Compare with concrete diction and abstract diction, above. It is also possible to separate diction into high or formal diction, which involves elaborate, technical, or polysyllabic vocabulary and careful attention to the proprieties of grammar, and low or informal diction, which involves conversational or familiar language, contractions, slang, elision, and grammatical errors designed to convey a relaxed tone."
ok so just one question: if you want to write a sentence on it, would you be like: The author uses pathos and ethos in this quote, "asdifjaosdf" to suggest blah blah?
That's the idea, yes. Of course, if you're writing about several literary terms, you'll need to vary the phrasing so they don't all read identically!
