INTRODUCTION

CORE DEFINITION

Portfolio assessment gathers a learner's work over a period, including drafts, finished pieces, and reflective notes, and evaluates the trajectory rather than one performance. The core proposition is that standardized tests capture a snapshot, while capability is a trajectory that only repeated samples can reveal. The key qualification is that the portfolio must be curated against explicit criteria: collecting everything indiscriminately produces a pile rather than evidence, and vague rubrics reduce the judgment to subjectivity.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Criteria first: define the dimensions and the rubric before deciding what to collect. - Evidence selection: require the learner to choose representative pieces and justify each choice. - Growth read: compare early and late samples on the same dimension to see actual change.

Anchor fast decisions

A single test conflates current capability with the conditions of that day, so it cannot distinguish improvement from noise. Repeated samples collected under varied conditions reveal the trend, and the learner's own reflections expose the reasoning behind each revision. Comparing early and late work on the same criteria converts an impression of progress into evidence.
