Abstract
This paper reports on early efforts to make sense of the new type of data created by Networked Function Based Algebra Generative Activities – specifically a data set from a single classroom activity consisting of over 1000 equivalent expressions. The data was collected during the first enactments of Networked Generative Activities in Singapore. The author led a series of networked generative, function-based algebra modeling activities with five classes of Secondary 1 students. The functions submitted by the students for a single activity were collected and analyzed. Findings showed that students created a range of correct functions utilizing many important mathematical concepts. Preliminary analysis of the functions highlighted the need for new and powerful tools for teachers to make sense of the vast quantity of data created in generative activities.
