Purpose For many people mathematics is one of the subjects that they have difficulty with. Yet, mathematics underlines many subjects in the real world. Thus, there have been many studies that investigate the ways of supporting students' understanding of mathematical learning such as using different models, real-life contexts, and problem-solving process. Today, many school programs focus on students’ problem-solving skills. Many countries renewed instructional programs in the way of encouraging problem-solving method. Similarly, problem solving becomes a more efficient element in school programs in Turkey. In other words, studying on problem solving processes and strategies also get essential in mathematics educations. The purpose of this study is to investigate the fifth and sixth grade middle school students’ use of strategies in the problem-solving process related to sets, whole numbers, fractions and decimal numbers and to evaluate their approaches and level of understanding during these non-routine problems. Method 29 fifth grade and 29 sixth grade students from a public school participated in the study. Students solved six non-routine mathematics problems related to problem-solving strategies such as guess and check, making a drawing, working backward, arithmetic strategy, algebraic strategy and organizing data. The students were given sufficient time for the problems and they worked on them individually. All problems included five sub-questions in order to understand their thinking process such as "what is given and asked in the problem?". The answers of these questions were analyzed in detail in order to understand their reasoning. Content analysis was used to categorize students' answers. During the analysis each student's answers were coded and then similar answers are regrouped. Results and Discussions During the instruction, students were able to develop and use different strategies for nonroutine problems. Fifth grade students were able to put at least two different strategies for each problem. They even used four different strategies in one of the problems. Sixth grade students were also able to put at least two different strategies for each problem. These results revealed that students have flexible thinking. Both fifth and sixth graders could comprehend the strategies and use them in similar problems. Furthermore, at least 76 % (22 students) of both fifth and sixth grade students were able to re-write the problem with their own words and explain the given as well as asked information in the problem. However, most of them had difficulties in organizing and relating the given information to reach the correct solution. They 711 also had problems in implementing their plans appropriately. The results indicated, even though students can rewrite the problems or find solution strategies; they often failed to find the correct answer. One of the reasons was students’ difficulties in planning to find the solution. Additionally, they had difficulties to apply the plan in correct order. Thus, it might be important to give students opportunities where they can practice non-routine problems and planning. During the solution of these problems, teachers need to not only focus on the answers but also the process of the students' solution strategies. Moreover, teachers need to ask students their plan to reach the correct answer and also check whether they can apply the plan they wrote. As students have more opportunities to solve these problems, they will develop more flexible mathematical thinking and reasoning

Investigating beliefs and perceived self-efficacy beliefs of prospective elementary mathematics teachers towards using origami in mathematics education
Arslan, Okan; Işıksal Bostan, Mine; Department of Elementary Science and Mathematics Education (2012)
The purpose of this study is developing valid and reliable scales in order to measure beliefs and perceived self-efficacy beliefs towards using origami in mathematics education and then, investigating beliefs and perceived self-efficacy beliefs of Turkish prospective elementary mathematics teachers in using origami in mathematics education. Furthermore, gender differences in prospective teachers' beliefs and perceived self-efficacy beliefs in using origami in mathematics education were investigated. Data fo...
An investigation of mathematics anxiety among sixth through eighth grade students in Turkey
Birgin, Osman; Baloğlu, Mustafa; Catlioglu, Hakan; Gurbuz, Ramazan (2010-12-01)
The purpose of the present study is to investigate mathematics anxiety among 220 sixth through eighth grade Turkish students in terms of mathematics achievement levels, perceived enjoyment of the mathematics teaching method, perceived enjoyment of mathematics, and perceived help with mathematics from parents. The Mathematics Anxiety Scale for Primary School Students (Bindak, 2005) was used to assess the levels of mathematics anxiety. A 3 x 2 factorial analysis of variance results showed that there was not a...
Investigating middle school preservice mathematics teachers’ conceptions of algebra and knowledge of task purposes and student thinking
Alapala, Burcu; İşler Baykal, Işıl; Department of Elementary Science and Mathematics Education (2018)
Starting with the beginning of the 21th century, teaching algebra in the early grades has gained more attention. Since teachers are one of the crucial factors in teaching early algebra, this study aimed to understand middle school pre-service mathematics teachers’ (PSMTs’) awareness about the underlying algebraic structure of given tasks, their conceptions of algebra, expectations about possible student solutions, and the changes after attending the algebra weeks in the Methods of Teaching Mathematics Cours...
The investigation of cognitive processes in mathematics learning with item response theory
Özkaya Seçil, Selcen; Berberoğlu, Halil Giray; Department of Secondary Science and Mathematics Education (2009)
The importance of learning mathematics and using it in daily life is obvious. On the other hand, the results from many national and international assessment studies show that the achievement of Turkish students are very far away from the bare minimum performance. However, in the measurement and evaluation procedures of both primary and secondary educational system, there is a lack of identification of this “bare minimum” or qualitative and clear descriptors for performance levels. A great importance is dedi...
Investigating Sources of Pre Service Teachers Self Efficacy For Preparing And Implementing Mathematical Tasks
YÜREKLİ, BİLGE; Işıksal Bostan, Mine; Çakıroğlu, Erdinç (2015-02-04)
The goal of this study was to understand pre-service teachers' self-efficacy beliefs for preparing and implementing mathematical tasks and to explore which sources of self-efficacy they wighted and interpreted when judging their capabilities as a result of attending a mathematics teaching methods course designed with a focus on mathematics teaching through tasks. Nine pre-service teachers participated in this study and they were interviewed at the end of the methods course. Findings revealed that methods co...
