During the process, writers must select from and combine these variables as appropriate to the writing tasks.
Writing is also a means for learning.
While writing to learn, students discover connections, describe processes, express emerging understandings, raise questions, and find answers. For example, students learn content in science or social studies through keeping a response or process journal, or a learning log. Additionally, the writing process is a thinking process. To produce a composition, writers must tap memory to establish what they know, review the information they have generated, and translate it into inner speech or print. They must organize main ideas into a logical sequence and discover specific support for those main ideas.
