"Det är lika mycket, för vi har inte tagit bort eller lagt tillnågot!" : Exemplifiering av hur organiserande syften kan användas som stöd för att skapa meningsfull kemiundervisning om materians bevarande i lågstadiet

Sammanfattning: The purpose of the study is to exemplify how the didactic model organizing purposes can be used in planning, implementation, and evaluation in order to create a meaningful teaching for students in primary school about the principle of conservation of matter. The study is a didactic design where we made an exemplification inspired by action research as a research approach. The research design consists of two whole and one started teaching cycle. In the first two cycles we have done a didactic design and analysis supported by organizing purposes, while in the third we have done one didactic design. A total of 23 students from year 3 have participated in the implementation of the teaching cycles, of which 12 participants in cycle 1 and 11 participants in cycle 2. To obtain data for the didactic analysis, we have used audio recording as a data collection method. The result exemplifies how organizing purposes supported our planning and evaluation about how we could incorporate mass preservation as a content in primary school in a meaningful way. It provided support for planning relevant purposes for the students that would at the same time lead to a progression towards the overarching goal of learning the principle of conservation. It partly supported us as teachers to focus on and direct the students' attention to what was relevant in relation to the overall goal of mass conservation. A conclusion is that the model was helpful and gave us a way of thinking about the learning objective, the overall purpose, could be achieved by providing support to direct students’ attention. And if the proximate purpose was understandable to the students and if they had goal-in-sight.  The use of a didactic model also gave us a conceptual apparatus to think about how we could create progression in learning and meaningfulness for the students.
