Grammer check: student's or students'

Question

When do i use student's and when do i use students' with regards to the following paragraph?

Aim: To determine if providing web-based lectures, which enabled students to view and re-view lecture material at any time and repeatedly throughout the semester, would result in improved student performance, as measured by students final end of session grade.

Answer 1

Aim: To determine if providing web-based lectures, which enabled students to view and re-view lecture material at any time and repeatedly throughout the semester, would result in improved student performance, as measured by students'  final end of session grade.

the 3rd 'student' should be students'.

my explanation is simple - at the beginning of your sentence you are using the plural/collective "students". consequently the final students refers back to this group & it is their possession.

"improved student performance", in order to remove redundancy, is actually a shortened version of  "improved performance of a student". becoz of this implication, the "student" remains singular & unchanged.

hope this helps

Answer 2

It's student's. Student's is plural. While students' shows ownership over something.  

Answer 3

Grammar check

Aim: To determine if providing Web-based lectures, which enable students to view and re-view lecture material at any time and repeatedly throughout the semester, would result in improved student performance, as measured by students' final end-of-session grade.

student's = something in possession of one student, referring to one student

students' = "their," referring to a group of students, something in possession of a group of students

Answer 4

When you use a plural-possessive, you do the apostrophe after the "s."  Check it out:

student's = belonging to the student (singular)

students = plural word for "student"

students' = belonging to the students (plural.)

Other examples:

The Simpsons' house (house of the Simpson family)

The boys' snacks (snacks belonging to the boys)

There are some exceptions for unusual spellings.  If a plural word does NOT end in "s," you do the apostrophe first.

examples:

The children's books (children is already plural.  add the 's)

The women's organization

The mice's cage

Answer 5

Aim: To determine if providing web-based lectures, which enabled students to view and re-view lecture material at any time and repeatedly throughout the semester, would result in improved student performance, as measured by students' final end of session grade.

I corrected only the final "students"

I'd help you more with this awkward paragraph, but I don't know the context.

Answer 6

student's

Answer 7

The first two people are wrong.  There should be no apostrophe in the first students.  The second one should say students'.  

Plural nouns do not need apostrophes.  

WRONG: "There were five book's on the shelf."  

CORRECT:  "There were five books on the shelf."  

Apostrophes show possession (think ownership):

WRONG:  "There were five books on Johns shelf."

CORRECT:  "There were five books on John's shelf."  

You put the apostrophe after the "s" if the word is both plural and possessive:

WRONG: "The waiter mixed up the customer's orders." (this implies there is only one customer who had multiple orders)

CORRECT:  "The waiter mixed up the customers' orders." (this shows there is more than one customer)

This really isn't hard at all.  It drives me crazy that so many students can't remember these simple rules!!!
