Making a portfolio is a significant activity for all pre-service teachers. It is a body of papers and reflection that demonstrate the teacher-in-training's development, skills, and experience. A good portfolio should consist of both on-campus and off-campus teaching experience to demonstrate how a pre-service teacher has improved in various learning settings.

In-campus experiences take place on campus. Pre-service teachers take classes, rehearse writing lesson plans, and occasionally teach their peers during this period. In the portfolio, they may insert sample lesson plans, activity sheets, what they learned, and feedback from their teachers. These documents demonstrate how they are going to become actual teachers.

Off-campus experiences occur through field study or teaching internships in actual schools. This is where pre-service teachers have the opportunity to teach real students. For the portfolio, they can put in teaching schedules, photographs of classroom activities, observation notes, student comments, and assessment from their mentor teachers. This section of the portfolio demonstrates their capacity to manage a class and implement what they learned in an actual environment.

A portfolio done in an organized manner displays the pre-service teacher's journey. It makes future employers or school administrators view their commitment and improvement. It also makes the pre-service teacher introspect on his/her strengths and weaknesses. In both in-campus and off-campus sections, honesty, creativity, and diligent work are essential in making a portfolio that accurately represents one's development.

In summary, preparing a portfolio for both off-campus and in-campus experiences is a worthwhile activity for all pre-service teachers. It assists them in monitoring their learning, enhancing their teaching, and preparing for the future career of education
