portfoliomenetelmään

Portfoliomenetelmä, also known as the portfolio method, is an educational assessment approach in which learners compile a collection of work items that demonstrate their skills, knowledge, and progress over time. The portfolio can include a variety of artifacts such as written assignments, projects, reflections, peer feedback, and evidence of collaborative activities. By centralizing these materials, educators can obtain a holistic view of a student's development rather than relying solely on single exam scores.

The method originates from the broader concept of assessment for learning, emphasizing ongoing feedback and self-reflection. Portfolios can serve different purposes: they can function as formative tools that guide learning, summative records for grading, or both. Many educational systems integrate portfolio assessment in subjects ranging from language arts to science and the arts, and it is increasingly adopted in higher education and professional training.

Implementation typically involves clear guidelines and rubrics that outline the criteria for inclusion and quality of portfolio items. Teachers may facilitate regular portfolio reviews, helping students set goals and monitor progress. Learners, in turn, are encouraged to annotate their work, explain learning decisions, and make connections among diverse pieces.

Research indicates that portfolio assessment can enhance critical thinking, problem‑solving, and self‑regulation among learners. It also allows educators to tailor instruction based on individual strengths and weaknesses. Critics note that the process can be time‑consuming for both teachers and students, and requires consistent standards to avoid subjective grading.

In practice, portfoliomenetelmä is most effective when embedded within a supportive school culture that values reflective practice, feedback, and continuous improvement. It can complement traditional tests and provide an authentic measure of learners’ abilities in real‑world contexts.
