This paper focuses first on the issue of measuring education. When we consider "education and equity," we tend to quantify educational outcomes and compare these figures with others. While it is necessary to consider "equity" (or inequity) through comparisons with others, if we quantify the achievement of outcomes and evaluate the management of the organisation, we fall into a "metric fixation." Next, the paper discusses the issue of meritocracy, presenting a perspective on abilities as social and communal rather than individual. Finally, it discusses the concept of "collaborative learning" as presented by the Central Council for Education Report of 2021. This report states the importance of respecting all others as valuable beings. In order to clarify the significance and value of the presence of others in educational relationships, the paper considers a certain high school discussion situation. "Equity" in education cannot be realised by comparing personal figures on a particular scale. If we wish to realise "equity," paradoxically, it is essential that we do not ask whether we are achieving "equity" through comparison with others. Being equally opaque to one another, being diverse, is essential for the realization of pleasurable "collaborative learning."
