STUDYING SOME COMMON MISTAKES OF GRADE 8 STUDENTS WHEN SOLVING THE PROBLEMS OF ANALYZING A POLYNOMI INTO FACTOR

Abstract

In the process of teaching and learning Mathematics, helping students realise and  rectify mistakes  would  create  favorable  conditions  for  them  to  inculcate  the knowledge  and  apply  it  to  solve  new  problems.  This study aims to investigate students’ mistakes when they learn the lessons of analytic polynomial problems (Algebra 8). This study aims to investigate of 40 test papers from students who studying in a secondary school located in Phu Yen province to identify the common mistakes. Then students participated the semi-structure interview to explain of the causes regarding to their mistakes and help correct them. Then, the author proposes some recommendations for  teachers  to  help  students  improve  their  ability  to  detect  and  correct  their mistakes. Teachers need to understand the causes of students' mistakes to come up with appropriate measures and teaching methods to help them correct mistakes effectively.

Key words: analytic polynomial problems, mistakes, learning through mistakes, grade 8
