Mathematical Modelling of a Social Problem in Japan: The Income and Expenditure of an Electric Power Company

  • Chapter
Mathematical Modelling in Education Research and Practice

Abstract

The problem of the income and expenditure of an electric power company was taken up as a teaching material for mathematical modelling. This teaching experiment focused on students making assumptions and validating results in mathematical modelling when posing their own solutions to the company’s financial deficit problem. As a result, it was confirmed that, in general, Japanese students are not able to make assumptions appropriately from complicated real-life problems and that students’ modelling skills in handling uncertain numerical values and conditions were acquired through their discussion about the correct answers. In addition, it demonstrated that it is possible to use mathematical modelling teaching materials which deal with the income and expenditure of an electric power company for instructing junior high school students in Year 9.
