The development of concepts in statistics and functions is an important part of the school mathematics curriculum. Also important is the formulation and verification of mathematical conjectures (National Council of Teachers of Mathematics 2000). This activity asks students to examine the effects on the descriptive statistics of a data set that has undergone either a translation or a scale change. They make conjectures relative to the effects on the statistics of a transformation on a data set. Students then defend their conjectures and deductively verify several of them.

THE CALL FOR THIS FOCUS ISSUE BEGAN BY reminding readers that in 1980, the National Council of Teachers of Mathematics made a strong case for including problem solving in the mathematics curriculum. Problem solving was not a new topic at that time—after all, George Pólya published his seminal work, How to Solve It, in 1945. However, the 1980 Agenda for Action publication marked the beginning of a period in mathematics education when the processes of problem solving received specific attention in the school mathematics curriculum. Problem solving became much more than solving word problems.

School Mathematics Curriculum

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.
