A thesis can be an argument or a descriptive summary, depending on your project. The thesis determines what can, and cannot, be included in the essay.
Consider the pieces of a jigsaw puzzle. If the picture for the jigsaw puzzle is a dolphin, then that is its thesis. In that case, only puzzle pieces that have parts of a dolphin belong in the puzzle. As well, all the pieces with dolphin on them must be put in the right place so that we can clearly understand that the picture is a dolphin.
Writing an essay with a strong thesis (or underlying picture) is the same – but it can be more challenging when you use words!
If you are clear about the goal of your essay and you know exactly what you want to tell your reader, then writing a thesis will come naturally.

Possible Thesis statements:
Remember, an effective thesis does not just list the ideas of the essay; it adds the author’s insight or conclusions about the content. The thesis must introduce a larger unifying idea to tie all the points together. In the example, the larger idea, the author’s insight, is the idea of active compared to passive learners.
Certainly, there can be many possible thesis ideas for any essay and this is just one example. Now, go back and review the practice thesis statement that you wrote for this essay. Which of the models does it most clearly resemble? Can you revise your thesis so that it is effective and provides a real conclusion about the topic?
