@Faith Womack I assume your exchange student is taking a number of courses. As a science teacher, I can help a little in that area. I tell my students to go to websites geared toward children. Just use a search engine and type in the subject area and the term "kids" or "children". Some sites I have directed students to include Chem4kids and Biology4kids. This particular site actually has several different areas for different subjects. The language used is simpler, so students can get the gist of more complex concepts. Then the student can read the textbook and hopefully pick up more information. Encourage the student to look at the pictures, diagrams and charts in the textbook. These suggestions are also great for any student who struggles with reading.
I also encouraged my ESL students to look up the subject area on the internet in their native language. I know they are supposed to be learning English, but they cannot progress in other subjects if they don't understand the concepts being presented. They just fall further and further behind. They have to take the tests in English, so they must figure out how to translate it and at least learn some keywords.
