The purpose of this research is understanding the use of bar model method used in Singapore math curriculum while solving algebra word problems in 7th grades and students’ reasons for the solution method preferences in solving algebraic word problems. The data were collected from 10 seventh grade students from a public middle school in Sincan, Ankara, in the spring semester of 2018-2019. In this single case study, an initial assessment was applied to 42 seventh grade students for selecting the participants. Students’ errors were analyzed and 10 students were selected. A threehour instruction about solving algebraic word problems with bar model method was provided these students. After the instruction, a clinical interview with each student was carried out. During these interviews, students solved the algebraic word problems with any method that they want and shared their thoughts about using bar model method. The results indicated that bar model is an effective method for remedying seventh grade students’ errors in solving algebraic word problems. Particularly, it resulted with a positive role on seven of 10 students’ performances. This study revealed that bar model method is useful for visualizing the problem content. Although some of the students experienced difficulties in solving problems, nine of the 10 students found this method easier and more interesting. They also preferred the bar model method instead of the algebraic equation method. Thus, this study suggests providing students with more oppourtunities to use the bar model method in algebra problems at various difficulty levels.

 The role of the Singapore bar model in reducing students' errors on algebra word problems Baysal, Esra; Sevinç, Şerife (2021-06-01) This study investigated the role of the bar model method, a significant aspect of the Singapore mathematics curriculum, in the remediation of seventh-grade students' errors on algebra word problems. To accomplish this purpose, we first assessed students' errors on a written test involving algebra problems and identified ten students based on the errors they demonstrated. These students were then offered instruction on how to use the bar model method. Following the instruction, we did clinical interviews and...
 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...
 An examination of the 7thgrade mathematics teacher’s guidebook in terms of the relationship between mathematics and science 7. Sınıf matematik öğretmen kılavuz kitabının matematikve fen derslerinin ilişkilendirilmesi açısından incelenmesi Yeniterzi, Betül; Işıksal Bostan, Mine (2015-01-01) Mathematics curriculum for 6-8 grades (MoNE, 2011) gives importance to make connection between mathematics and other disciplines. This program emphasizes that connection is effective on students for noticing mathematics in real life and understanding other disciplines. When mathematics and science curricula investigated together, common skills such as; critical-creative thinking, questioning, problem solving, etc. attract attention in both curricula. This connection in mathematics is also reflected on the t...
 An investigation of middle school mathematics teachers' knowledge for teaching algebra Yilmaz, Nurbanu; Erbaş, Ayhan Kürşat (2017-01-01) The purpose of this study was to investigate middle school mathematics teachers' knowledge for teaching algebra. The participants of the study were 48 mathematics teachers from various middle schools. A questionnaire was conducted in order to collect data about the teachers' knowledge related to teaching of algebra. The results showed that the participating teachers were competent in making transitions among different algebraic representations. However, they had difficulties in explaining the conceptual bas...
 Cebir Problemlerinin Çözümüne Yeni Yaklaşım: Singapur Şerit Model Yöntemi Baysal, Esra; Sevinç, Şerife (2020-08-01) Bu çalışmada, yedinci sınıf öğrencilerinin cebir problemlerini çözmede tercih ettikleri yöntemleri ve öğrencilerin Singapur çubuk model yöntemi hakkındaki görüşleri incelenmiştir. Tek durum çalışması olarak tasarlanan çalışmada, yedinci sınıf öğrencilerinden cebir problemlerinin sorulduğu ön değerlendirme testinin cevaplarına göre seçilen 10 öğrenci ile klinik görüşmeler yapılmıştır. Öğrenciler ders saatlerinde yedinci sınıf matematik öğretim programına uygun olarak cebirsel denklem kurma yöntemi ile proble...
