ABSTRACT
Within the phenomenographic research tradition, the object of learning depicts the capability that is to be learned by the learner. It has been argued that the object of learning cannot be fully known in advance since what is to be learned depends on the learners as well as on the content taught. The object of learning and its nature needs to be explored. In this paper, we analyze how a group of teachers collaboratively investigated an object of learning when they planned, enacted, analysed, and revised a mathematical task. We describe distinctions made by the group in the inquiry into teaching and learning, and how delimitations and distinctions made transformed the teaching and meaning of the object of learning.

Notes
1By capability, we refer not to general capabilities, but instead content-specific skills or ways of knowing.
2For several reasons, the fourth lesson did not follow the intended plan and is therefore excluded in our analysis.
3The positioning system for numbers was handled in another part of the lesson and was not in the task.
4Division can be seen as “partitioning,” for example, 100÷50 as 100 divided in 50 piles, or as “measurement”, how many times does 50 go into 100 (cf., Greer, Citation1992).
5When the team explored the external horizon of the object of learning during phase 3, they realized that simpler items were needed to reduce the impact of the calculation aspect. This finding resulted in a change regarding the numbers in the task ().
