Dialogista argumentaatiota matematiikkaan ja fysiikkaan

Experimenting with the structured assessment dialogue in physics and mathematics classes

Teacher–student discussions are central in assessing students’ skills and knowledge. This study deals with formal, pre-planned discussions to assess students’ inquiry competences. The method is called the structured assessment dialogue (SAD) which combines formative and summative assessment. Six SAD sessions (4 lower secondary physics and 2 upper secondary math) were implemented at the end of inquiry lessons. The SAD sessions were video recorded and the discussions were analyzed using theory based categories and networks. The results showed that the truly novel SAD method in Finnish classrooms challenged teachers and students. For example, students usually gave lower order answers although …

Recognising Articulated Reasoning in Students' Argumentative Talk in Mathematics Lessons

Previous studies have reported difficulties in analysing students’ argumentation. Especially the warrant, which connects data with claims, is found to be problematic to recognise. Weexamine how specific criteria for different forms of reasoning could decrease this difficulty. Instead of identifying warrants, we recognise whether students’ argumentation contains explicitly stated reasoning. We have developed an analysis method for recognising reasoning in argumentative talk. We collected video data from two mathematics lessons where students had to state claims about a mathematical situation and build convincing justification for their claims. The focus of analysis is in how the students art…

Mathematics Learning through Arts and Collaborative Problem-Solving : The Princess and the Diamond-Problem

In this paper, we examine a mathematics education course which focused on collaborative mathematical problem solving in art topics. The students of the course were Finnish primary school pre-service teachers. During the course students investigated tessellations, reflected on their experiences and designed workshops for pupils. The course meetings were video recorded. Students’ work contained elements of mathematical problem solving and gave them experiences of working collaboratively. The topic of tessellation was found suitable for this purpose. peerReviewed
