[V意向形]と思う: meaning, usage and examples
[V意向形]と思う means: I think I'll [Verb Volitional-form].
How to form it
<Verb volitional> + と思う / と思っている (行く → 行こうと思う / 食べる → 食べようと思う / する → しようと思う)
Examples
来年、大学院に入ろうと思っています。
I'm thinking of entering graduate school next year.
今日は早く寝ようと思います。
I think I'll go to bed early today.
週末は部屋の掃除をしようと思っています。
I'm thinking of cleaning my room on the weekend.
今晩は家で料理を作ろうと思います。

When to use it
Shares a decision or plan the speaker is making: 'I think I'll do X' or 'I'm thinking of doing X'. と思います often shows a decision made just now; と思っています shows a plan you have had for some time. Use it to talk about your own plans in a soft way: 来年、引っ越そうと思っています.
Nuance
Softer and less fixed than つもり: the plan may still change. With と思う the subject is the speaker (in a question, the listener). For another person's plan, use と思っている: 田中さんは留学しようと思っています.
Compare
Compare つもり (firm intention): 行くつもりです sounds decided, 行こうと思っています sounds like a plan under consideration. Compare plain form + と思う (a guess): 雨が降ると思います 'I think it will rain' is a prediction, not an intention.
Tip: Volitional + と思う is for your own actions; plain form + と思う is for guesses. 行こうと思う 'I think I'll go' vs 行くと思う 'I think he'll go'.
