  This paper aims to increase the insight into kindergarten teachers’ justification of their teaching. The study was done in a context with mathematical activities developed by the researchers in collaboration with the teachers. This is a context we consider as rich to reveal their choices and justifications made in advance of and during the teaching of a mathematical activity. Data from a semi-structured, post-teaching stimulated recall interview based on an activity with 5-year-old children was analysed employing the Knowledge Quartet proposed by Rowland et al. (2005). We identify seven choices made by the kindergarten teacher that reveal aspects of the kindergarten teacher’s knowledge-in-action and knowledge-in-interaction. She adapts the activity through questions, comments, particularities within the activities, and use of artefacts. Thus, she nurtures the children in their mathematical learning process.

  Abstract: This study tests an intervention that introduces a structured curriculum for five-year-olds into the universal preschool context of Norway, where the business as usual is an unstructured curriculum. We conduct a field experiment with 691 five-year-olds in 71 preschools and measure treatment impacts on children’s development in mathematics, language, and executive functioning. The nine-month intervention has effects on child development at post-intervention and the effects persist one year following the end of the treatment. The effects are mainly driven by the preschools identified as low-quality at baseline, indicating that a structured curriculum can reduce inequality in early childhood learning environments.

  In this study we investigated qualities of the mathematical discourse in four kindergarten classes in which kindergarten teachers and 5-year-old children engaged in mathematical learning activities. We analysed differences in the mathematical discourses in two experimental kindergarten classes and two control kindergarten classes, in a research and development project. The overarching research question guiding our study was as follows: what characterises the mathematical discourse unfolding in kindergarten classes? In our study we drew on the theoretical framework Mathematical Discourse in Instruction coined by Adler and Ronda, as we quantified the collected qualitative data. Our analyses identified significant characteristics of mathematical discourse with respect to the children’s opportunities to contribute with ideas and arguments. The discourse in the kindergartens differed both with respect to the extent and nature of verbal utterances among the participants, as well as the mathematical engagement nurtured amongst the children. Moreover, the mathematical discourse within the experimental kindergarten classes, to a greater extent than that in the control kindergarten classes, initiated opportunities for the participating children’s mathematical learning.

  The aim of this paper is to report results from a three-year project concerning collaboration with kindergarten teachers in implementing mathematics in the kindergarten. In our co-learning with the kindergarten teachers we all participated in a developmental project. The frame for analysing our data was developmental research. The analysis shows that the kindergarten teachers changed their practice throughout and because of their participation in the project. These changes were exemplified through increased mathematical consciousness in orchestrating mathematical activities, emerged emphasis on disseminating thoughts and ideas to colleagues, and changed ways of communicating with the children.

  The aim of this study is to address the subtleties in the process of how kindergartenteachers orchestrate mathematical activities with a group of children. Drawing on asociocultural perspective on learning and development, talk-in-interaction, emergingfrom naturally occurring data, has been analysed to get insight into how akindergarten teacher orchestrate mathematical activities. The analyses show that thekindergarten teacher's use of questions, which we categorise into six groups, playeda significant role in the orchestration of children?s learning process. Through the useof questions and a pair of scales, verbal and non-verbal responses were engendered,relevant mathematical terminology was offered, and an inquiry approach towardsmeasuring as a mathematical topic was initiated.

  This paper is based on data from a case study at a secondary school in Norway. The aim of the paper is to present an analysis of the nature and content of two teachers? reflections on the use of ICT tools in mathematics at grade 9. A central method in the study is the use of focus group interviews to gain insights into teachers? perspectives. Here we see two teachers reflecting on use of ICT in their mathematics teaching recalled by a video recording of three students? work in their lesson. A table is presented with questions addressing the reflections from the teachers. The table indicates teachers? ability to address a variety of questions, both linked to the concrete activity recalled by the video and on a more general level concerning ICT teaching in mathematics.

  The teachers in this study are participants in the LCM - (Learning Communities in Mathematics) project run at Agder University College. The project emphasises the development of communities of teachers and researchers focused on inquiry in mathematics and teaching. This paper deals with a well-planned lesson in an eleventh grade class in a Norwegian upper secondary school. We will present data that illustrate how the teachers intervened to reach certain goals that had been identified through the planning process. These interventions identified discourses, which showed that there was a discrepancy between how the teachers interpreted and used a certain word for a mathematical concept and how the students interpreted the same word. Our findings illuminate common challenges faced when trying to build a community of inquiry in the classroom.

  Alle børn skal have de bedste forudsætninger for at starte i skole. Det er derfor vigtigt at stimulere de områder, som baner vejen for en vellykket skolestart. Legebaseret læring er udviklet med netop dette formål. Materialet bygger på den nyeste internationale forskning inden for tidlig stimulering af sociale kompetencer, selvregulering, sprogudvikling og matematisk forståelse, og det indeholder et væld af aktiviteter, som understøtter børns udvikling inden for disse områder. Med Legebaseret læring får du helt konkrete anvisninger til, hvordan du kan understøtte læring gennem leg. Materialet rummer også ideer til, hvordan du kan sammensætte aktiviteter til sammenhængende forløb, udforme dagsplaner, årshjul mv. Legebaseret læring er udviklet og afprøvet i et tæt samarbejde mellem forskere og pædagoger fra mere end 80 daginstitutioner.

  Som en del av LCM-prosjektet har lærerne blitt oppfordret til å gjennomføre systematiske undersøkelser for å utvikle egen praksis. Doktorgradsstudentene diskuterer enkelte sider med slike systematiske undersøkelser motivert av designforskning, Japansk "lesson study" og aksjonsforskning.
