请教 portfolio的中文意思？

今天收到儿子高中中文班老师的email,问我这个"native speaker“"portfolio"的中文翻译。我查了查，很难找到很确切的中文翻译.发在这里，看大家有没有好的建议。Thanks.
Here is the email from his teacher:
”I have a question for you as a native speaker. My
students in all classes this year will be compiling portfolios, which
are individual collections of work in a subject area. They'll include
projects, journals, and things like that. What is the word for this in
Chinese? I've looked at some online dictionaries but the words I come
up with are clearly not this meaning of portfolio...I'm not sure this
concept is commonly used in China's schools, but maybe there's a word!“
