A teacher can use student portfolios to evaluate learning performance and p
romote learning outcomes. The portfolios can also be used as a communicatio
n channel among students and teachers as students implement them on the web
. However, it is burdensome for teachers to obtain the required information
to determine student learning status. This study describes how to design a
web portfolio system that enables teachers to use information technologies
to guide and evaluate student learning processes, Teachers can utilize thi
s design to analyse the web portfolios online to improve instruction, under
stand the progress of students and guide their learning. An evaluation of t
he web portfolio system by students indicates that the applied technologies
help students control their learning processes through developing portfoli
os. Students also believe the web portfolios serve as an effective communic
ation channel and media that can increasingly integrate their learning outc
omes for assessment purposes.
