Abstract:
The purpose of the present study was to investigate the Grade 9 students' ability to solve real-life and modelling problems, focusing on proof and reasoning. The study conducted using qualitative method in which, six volunteer students participated. The data collected via eight problems mostly chosen from Chapter 3 of the 9th grade mathematics textbook and using Adobe Connect Platform, because of Covid-19 Pandemic and schools clousure. The data were analyzed using a problem solving framework developed by Mason, Burton and Stacey (2010) including three stages of entry, attack and review. The results showed that considering these three steps, is effective to understand students' problem skills as well as considering these three stages in teaching and improving students' problem solving skills focusing on proof and reasoning
