請教 portfolio的中文意思？

今天收到兒子高中中文班老師的email,問我這個"native speaker“"portfolio"的中文翻譯。我查了查，很難找到很確切的中文翻譯.發在這裏，看大家有沒有好的建議。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!“
