5. The consequences of assessment (Pettersson, 2005)

6. Classroom assessment • Summative assessment Test on a local or national level • Formative assessment “all those activities undertaken by teachers, and/or by their students, which provide information to be used as feedback to modify the teaching and learning activities in which they are engaged” (Black and Wiliam, 1998)

7. Feedback Information provided by an agent (e.g. teacher, peer, book, parent, or one’s own experience) about aspects of one’s performance or understanding” (Hattie, 2009)

8. Feedback • Feed back what has happened ← The teacher evaluates the student´s demonstrated performances in terms of ”good” or ”bad”. Rewarding. Punishing, approval, disapproval • Feed forward the future → The teacher use the student´s demonstrated (lack of knowing) as a basis for continued learning • Feed up Students´demonstrated knowing ↕ explicit goals/criteria that should/could have been reached and/or to be reached in the future

9. In Sweden Presence of Assessment acts in Classroom visited • Feed back 58 • Feed forward 72 • Feed up 2

10. Analysis of knowledge Therefore the analysis ought to focus in what extent the pupil has access to his/her knowledge in different situations. Higher quality can e.g. be that the pupil shows his/her understanding of a concept in different ways and in different situations.

12. Weakness in understanding are often pinpointed by weakness in representations. Deep understanding of a mathematical item or topic is displayed by the ability to transfer the idea between different representations: pictorial, verbal, symbolic and the real world. (Alistair McIntosh)

13. Four kinds of representations Event The fishing huts Number Picture # 1 1 + 1 · 4 = 5 # 2 1 + 2 · 4 = 9 # 3 1 + 3 · 4 = 13 # 4 1 + 4 · 4 = 17 etc Word Symbols First I built a hut with 5 sticks, then I built a second hut with 4 sticks. After that I continued … 1 stick + 4 sticks for each new hut 1 st + 4 st · number of huts 1 st + 4 st · n 1 + 4 · n 1 + 4n 4n + 1
