1). It is argued that learning (including potentials and dilemmas that may occur) can only be meaningfully interpreted against a historical examination. The tensions, problems or contradistinctions that may occur along an activity are the sources of change and continued development, thus giving rise to cycles of transformations and re-conceptualisations of objects and/or motives. 1. “Third Generation CHAT” by own creation – own work Because Cultural-Historical Activity Theory allows for the identification of conflicts and the origin of multiple or sometimes contradictory voices but also cultural tools and rules that mediate these processes, it has been utilised by many researchers as an analytical lens to make sense of the complexity of learning processes.
I have followed the development … and it is all about: results, result, results. … The ranking means that schools are tried and tested (målt og vejet). Fundamentally I am not against it. But the problem is, as I see it, it is more interesting to focus on the improvements, rather than to focus on the comparison of schools, which are not comparable.
Academic skills, and produces reliable test results that can be used to compare and rank students, teachers and their schools. Standardised tests have to presuppose standard conditions of what can be expected from students and their teachers. Activity Theory provides a theoretical lens to show that school reality is a lot more complex than what can be expected from a ‘standard’ child because human development is shaped by a complexity of factors including rules and practices that shape and navigate experiences.
