I'm not a fan of that wording due to a lack of information, but I think something making it explicitly clear that you are looking for a temporary co-op block or internship is helpful. First, when recruiting, companies will often be looking for co-op and full time positions at the same time. This makes it very easy for the people (and there are lots of people involved - HR, hiring managers, the people visiting your university doing recruitment, who may be alumni and not part of the rest of the hiring process) looking at your resume know which category you fall in without having to think about your graduation date. Second, many companies keep your resume "on file" for a set period of time, looking to match you with any new positions and being able to see on your resume that you were a co-op candidate helps them.
As someone who has recruited and interviewed co-ops before, I want to see this information easily. At a typical university career fair, I only have a few minutes to talk to you. If I have to ask you if you're looking for a co-op or full-time position, when you want to start, and if you have prior university-approved co-op blocks and then write that down on your resume so it gets back to HR, that's less time that I can learn about your fit for the position or tell you about the company and the work that we have available. Where I recruit, we do a dozen or so on-site interviews the day after the career fair, so that 5-7 minute meeting at the career fair is where I decide if I'm going to bring you in for a 30 minute interview screening the next day.
As a student who had to do co-op blocks as a graduation requirement, those were the only time that I ever included a "Purpose" section on my resume (at the top, right below my name and contact information). I used that section to identify that I was looking for a required co-op or internship experience of a certain duration starting in a specified time period and what types of things I was hoping to do during this block. I also clearly identified how many co-op experiences that I had, as some companies did not hire first-time co-ops/interns.
