As computer and Internet technologies advance, their effects have become evident in various areas of mathematics education. Many technologies (e.g., math applets, online games, math software) provided interactive learning environments within which students can work with multiple representations of mathematical ideas and easily observe the effects of their activities. Many researchers have underlined that the dynamic feature of technology might draw students’ attention into mathematical concepts and enable them to identify the connections among various mathematical ideas. The interactive feature of current technology has already made static textbook images obsolete for mathematics instruction. Thus, current math textbooks have just began provide interactive learning environments through providing additional CDs, DVDs, or websites rather than spending lots of pages for static images or pictures. As a result of this, current math textbooks tend to become thinner than those in the past. Many researchers have also pointed out this changing feature of math textbooks. The following video gives some insights about how technology will change the future math textbooks and assessment of students’ math learning.
