Emphasis is on the student's daily work. Parents can actually see what their child is doing over time and discuss it with the teacher. And students aren't the only ones benefiting from portfolios. Teachers are creating them to showcase their own skills and work histories. Portfolios capture students' progress and provide insight into their development.
Portfolios let teachers know their students better and keep track of how they're progressing.
Portfolios are also valuable tools for teachers to chart their professional careers. Portfolios are a practical means of assessment that can measure progress and achievement in a way that can be shared with students, teachers, families even with new schools. Portfolios are purposeful, collaborative, self-reflective collections of student work generated during the process of instruction.
