6. In Saudi Arabia, there is a considerable attention toward improving Mathematics and science textbooks after the Saudi Arabia first participation in the third Trends in International Mathematics and Science Study (TIMSS).
The disappointed test results of students' performance in (TIMSS) were a high alert to rise the quality of education particularly in mathematics.

7. policy makers in the Ministry of Education have emphasized reforming textbooks alongside many improvements in Mathematics education since textbooks content mostly reflect what happened in the classrooms.

8. After many stages of reform and improvement, the first edition of the new mathematics textbooks series was released in 2007 for primary schools and middle schools , and in 2008 for secondary schools.
In 2010 the new series has been adopted in mathematics classrooms by all Saudi schools
The whole series was developed and revised by the Ministry of Education.

10. As all teachers in Saudi Arabia are required to adhere to the textbook as a main resource for teaching this study aims to:
Examine to what extent the new textbook in Saudi Arabia reflect the mathematics curriculum goals in problem solving.
2) Address the following question: how the new national middle school mathematics textbooks in Saudi Arabia represent problem solving heuristics?

12. A heuristic is “a general suggestion or strategy, independent of any particular topic or subject matter, that helps problem solvers approach and understand a problem and efficiently marshall their resources to solve it” (p. 23). Schoenfeld (1979)

13. Martinez (1998) stated heuristics "is a strategy that is powerful and general, but not absolutely guaranteed to work. Heuristics are crucial because they are the tools by which problems are solved" Heuristics are tools that may make solving problems easer

15. Guess and check
Make a reasonable guess of the answer, and check the result against the conditions of the problem to see if it is the answer.
Look for patterns
Observe common characteristics, variations, or differences about numbers, shapes, etc in the problems to find a solution.
Work backwards
Attack the problem from the outcomes or conclusions backwards to find what conditions the problem solver eventually need.
Draw a diagram
Draw a graph based on the information to visualize the problem.
Make a list
Construct on organized list containing all the possibilities for a given situation and find the answer.
Simplify the problem
Change the complex numbers or situations in the problems into simpler ones without altering the problem mathematically.
Act in out
Use people, objects to physically show what is exactly described in the problem.
Restate the problem
Approach the problem from a different angle.
Use equations
Use the letters as variables to represent unknown quantities.
Use a model
Translate the problem in different way by Using lines, points.
Use Venn diagram
Represent the problem by using Venn diagram.
Logical reasoning
Reasoning from one or more true statements.
Draw a picture
Drawing figures or graphs.
Think of a related problem
Recall related problem solved before to solve the recent problem.

17. Textbook analysis :
In this study, we analysed the student books as each textbook consists of student book and work book.
Analysis procedure was based on problem solving heuristics introduced in the main text, e.g., in examples, due to teachers using them in class discourses or groups work.

18. We assigned the units that contain mathematical problems.
:Coding procedure
We assigned the units that contain mathematical problems.
We categorised the heuristics we had found.
We measured the reliability of coding, by inviting external coder. The Inter-rater Agreement according to the Intra-class Correlation Coefficient (ICC) was 0.98 on heuristics in general and 0.97 on heuristics existence in each book thus, this result indicates a high agreement in coding.

19. the study Results
The results from the coding revealed that the Saudi middle school textbooks represented a variety of problem solving heuristics and the results can be seen in Figure 1.

21. Fourteen different heuristics are introduced in the three books.
The majority of problems in the three textbooks were solved based on Polya's four stages.
The data revealed that grade 8 textbook represents the highest number (12) of the (14) heuristics, followed by grade7 (11) heuristics and the lowest number was coded in grade 9 (9) heuristics.

22. "guess and check" and "look for a pattern" are nearly the most frequently used heuristics represented in the 7th and 8th grade textbooks, whereas these heuristics seem to be less present in grade 9 textbook.
The result is interesting in comparison with what Fan and Zhu found in their study, namely, "guess and check" and "look for a pattern" were the least frequently used heuristics in mathematics textbooks in China, Singapore and USA at the lower secondary grade level (Fan & Zhu, 2007)

23. In the grade 7 textbook, we can find that the most frequent heuristic is "think of a related problem", whereas in the grade 9 textbook, there is no "think of a related problem" heuristic at all.
The numbers of "logical reasoning" and "use equations" heuristics in the three books are increased gradually from the grade 7 to 9 textbooks.

24. "use equations" is the major problem solving heuristic represented in the grade 9 textbook.
Polya (1973) once explained that using equations is like “translation from one language into another and the difficulties which we may have in setting up equations are difficulties of translation”

25. There are 11 and 9 examples using the "work back word" heuristic in the grade 7 and 9 textbooks respectively.
Charles and Lester (1984)’s study found that using a verity of heuristics like logical reasoning, work back word and make a list for teaching Grade 5 and 7 students improved students' ability to understand the problem and choose the right solution to solve the problem.

26. "use a model", " use Venn diagram" and "make a systemic list" are the least frequently heuristics used in both grade 7 and 9 textbooks, whereas these heuristics are represented frequently in the grade 8 textbook.
Fan and Zhu (2007)’s study reported that "act it out" and "use a model" were among the four least heuristics presented in China, Singapore and USA textbooks. It seems worth further investigation on whether using "act it out" and "use a model" are more appropriate for students at certain levels with certain backgrounds

27. Most heuristics in the three textbooks are introduced and labelled as special topics, which reflects the textbooks authors' vision of focusing on heuristics as a tool to solve problems.

28. Summary and conclusion

29. The results to a large degree indicate how problems solving is being taught in Saudi classrooms and it is clear that problem solving heuristics get a very high attention in middle schools textbooks
As the majority of examples were solved by one heuristic, we suggest it will be helpful when such problems are solved by two or more heuristics, when it is appropriate, so the students can learn from different solutions for the same problem.

30. The frequency of using some types of heuristics was low in some textbooks whereas, the frequency of these types was high in other textbooks.
It is necessary for textbooks developers and mathematics educators to consider heuristics' distribution in the three textbooks and reconstruct these heuristic regarding the usefulness of these heuristics to the students at this level.

31. The three textbooks represent and label problem solving heuristics as specific topics and that might lead teachers and students to treat these heuristics separately.
It would be beneficial to consolidate the heuristics with other topics to help students to tackle the problem better.
