Because claims serve so many roles, you will find that in the LRS materials we use three names for claims. You can think about claims from three perspectives:
We call a claim a solution when we are thinking about how it answers the problem or question that gives your readers a reason to read your paper. If your paper begins by showing readers that they have a problem you can solve or a question you can answer, then the most important part of your paper will answer that question or resolve that problem. A solution can therefore be an answer to a question (if yours is a conceptual problem, something they don’t know) or a recommendation of how to solve the problem (if yours is a practical problem, something they need to act to resolve).
We call a claim a claim when we are thinking about arguments. If your solution is obvious or self-evidently true, then you don’t need a paper to support it. But when readers are not likely to accept your answer or recommendation at face value, then it is something you claim to be correct – something that you will then support with a sound argument.
We call a claim a point when we are thinking about the structure of your paper. For readers to think that your document is coherent, they must see a sentence or more that states its point: the most important idea in the document, the one that the rest of the document supports, and the one that forms the basis for the organization of the rest. Documents must have points, even when they do not raise and solve a problem. But when they do, the main point of the document is what you claim to be the solution to the problem you present. If this sounds a lot like what you might already know as a thesis, there's a good reason for that: the term thesis is just another way to indicate what we're calling an argument's main point.
