Mokros, J. The student lost the results of the third and sixth measurements. Russell, S. In a study that compared the coursebooks in the USA, Taiwan, and China in terms of the concept of arithmetic mean, Cai, Lo, and Watanabe evaluated arithmetic mean problems under three categories. TR7 included problems of types A1 and C4, but no problems asked in the multiple form. Since the arithmetic mean is 3. Educational Studies in Mathematics, 12, — Kaynar, Y. Table 4 presents the results on the strategies and the representation forms used in the solution of the problems in the coursebooks. Tidsskrift for Den norske legeforening E. If mean of elements and ask the total number contribution of each of them is 50 TL, what is the total amount paid for the present? The coursebooks included in the study were those used in Turkey in the — academic year.

Document analysis as a qualitative research method.

Most problems in the coursebooks were verbally developed, and the problems were solved only via the add—divide algorithm. Mathematical Thinking and Learning, 12 2 , — Two problems that examine whether the arithmetic mean is conceptually understood Problem 3. A comparison of Korean and American secondary school textbooks: The case of quadratic equations. Dikey Analiz 3. Teaching Children, 2 6 , In summary, several studies on the international and national scale demonstrated that Turkish students have difficulty related to the concept of arithmetic mean and are not familiar with conceptual understanding. For example, the students who use the add—divide strategy mostly preferred symbolic representation. An experimental study conducted by Hardiman et al. University of Pittsburgh, the USA. Journal of Mathematics Teacher Education, 9, 53— Educational Studies in Mathematics, 12, — The outcomes related to the concept of arithmetic mean in Turkish coursebooks and the time allocated to the outcomes The results related to the concept of arithmetic mean, which is one of the statistics concepts, in Turkish coursebooks are included in grades 6 and 7. The representation forms used in the presentation of the problems were evaluated in three categories, namely, verbal representation, visual representation, multiple representation; moreover, the representation forms used in the solution of the problem were evaluated in four categories: verbal, picture, manipulative, and symbol, as shown in Figure 4.
