This research is part of the project Interaction and Knowledge, whose main aim is to study and promote peer interactions as one of the possible forms of developing pupils’ socialisation and positive attitudes towards mathematics, as well as to promote their socio-cognitive development and enhance their school achievement. In this paper we analyse a case that illustrates the role of peer interactions in knowledge appropriation in a statistical task. Doerr, H., M. & English, D. L. A modelling perspective on students' learning through data analysis . (Vol. 2, pp. 361-368). A modelling approach to problem solving shifts the focus of the learning activity from finding an answer to a particular question to creating a system of relationships that is generalizable and re-usable. In this research paper, we discuss the nature of tasks that can be used to elicit the development of such systems. We present the findings from one classroom-based case study of Australian children and a summary of findings from all U.S. and Australian classes in our studies. Student reasoning about the relationships between and among quantities and their application in related situations is discussed. The case study suggests that students were able to create generalizable and re-usable systems (or models) for selecting and ranking data.

63 Gattuso, L. & Mary, C. Pupils’ perception of the links between data and their arithmetic average. (Vol. 3 pp. 25- 32). The results presented in this paper are part of a larger study on the strategies used by pupils to solve arithmetic average problems. The arithmetic average being a widely used concept, it is important to study pupils' knowledge and their difficulties in order to improve their learning. Two questions arose from previous studies: 1) up to what point do pupils perceive the links between data and their average? And 2) does the introduction of a null datum(=0) complicate the situation? A first task asked for an estimation of the effect of the modification of a datum on the average and a second required finding the datum which would leave the average unchanged. The results tend to demonstrate that pupils have a fairly good perception of the effect of data modifications on the average with better results if the datum is zero. Murtonen, M. & Merenluoto, K. Novices’ and experts’ knowledge on statistics and research methodology. (Vol. 3, pp. 391-398). Many social science students in university constantly experience difficulties with research methodology and statistics courses. In this study we compared novice students’, advanced students’ and experts’ knowledge on these complex and difficult domains. The results of the study refer to a tendency for novices, especially when they have had problems with mathematical subjects, to place the contents to emotional or other irrelevant categories which restricts or blocks their other cognitive activities on these subjects. There was a remarkable difference in the fragmentation of concept maps and explanations between novices, advanced students and experts. The novices were also not able to use sufficient representations to understand the concepts.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
