    Cultural historical analysis of Iranian school mathematics curriculum: the role of computational thinking
    (Universitas Sriwijaya; Indonesian Mathematical Society (IndoMS), 2021-09) Rafiepour, Abolfazl; Farsani, Danyal
    In this paper, six mathematics curriculum changes in Iran will be reviewed, spanning from 1900 until the present time. At first, change forces, barriers, and the main features of each curriculum reform will be represented. The first five curriculum changes are described briefly and the sixth and most recent curriculum reform will be elaborated. In this paper, we call the last reform as contemporary school mathematics curriculum change. This recent (contemporary) curriculum reform will be explained in more detail, followed by a discussion of the effect of globalization and research finding in the field of mathematics and mathematics education (in the Iranian mathematics curriculum). In total, three key ideas are distinguished as an effect of globalization which is “New Math”, “International Comparative Studies”, and “Computational Thinking”. Finally, the paper comments on the necessity of paying more attention to information and communication technology as part of globalization; in particular, recall policy-makers to consider “Computational Thinking” as an important component of future curriculum design.

    Developing conceptual understanding of Irrational numbers based on technology through activity system
    (City University of New York, 2022) Rafiepour, Abolfazl; Abdolahpour, Kazem; Farsani, Danyal
    The main purpose of this study is to develop a conceptual understanding of the irrational number of the square root of 2 ( 2 ). Participants in the study were 20 ninth-grade male students. Activity Theory was used as a framework to show the development of the conceptual understanding. Since this study was conducted during the COVID-19 pandemic; online teaching method was adopted. In this teaching method, WhatsApp messaging and calculator were used as our basic technology. Virtual education lasted 2 sessions (120 minutes) for the development conceptual understanding of the irrational number of square root of 2. To produce data, WhatsApp Export Capability was used. For data analysis, the online teaching activity system was used. By analyzing this activity system, three tensions were understood. Modifying these tensions, has led to their students making the concept of the irrational number of the square root of 2 ( 2 ) and reach a single definition

    Modelling and applications in Iran school mathematics curriculum: voices of math teachers
    (City University of New York, 2021) Rafiepour, Abolfazl; Farsani, Danyal
    In this paper, six mathematics curriculum changes in Iran are reviewed, spanning from 1900 to 2021. Change of forces, barriers, and the main features of each reform are represented. Specifically, the first five curriculum changes are described briefly and the sixth and most recent one is elaborated upon, with more detail as contemporary school mathematics curriculum change. This recent curriculum reform will be then analyzed using an application and modeling approach, followed by reflections from five teachers of mathematics’ voices about how they implemented recent curriculum reform after passing modelling course in their master’s program. These teachers shared their professional beliefs about the role of the modelling course in shaping their classroom practices. We believe that the practical aspects of this paper can have enormous implications for other mathematics teachers in developing countries.
