Newman, Error Analysis, Story Problems, Systems of Three-Variable Linear Equations.Abstract
This research was motivated by the problems faced by students in solving word problems in
the System of Three Variable Linear Equations (SPLTV) material. The data analysis technique used in
this research is qualitative descriptive analysis, namely with the steps 1) data collection, 2) data
reduction/condensation, 3) data presentation, 4) drawing conclusions. The data collection technique
used in the research was a written test in the form of five story questions and interviews with 5
students who were selected based on the type of error made based on the Newman procedure which
aims to explore the causes of the error and further identify the error that occurred. The subjects used
in this research were all 21 class X (Ten) students. The results of the research concluded that 2.86%
of students made reading errors caused by students misreading the numbers or symbols in the
problem, 11.43% of students misunderstood the problem which was caused by students not
understanding what they knew and asked in the question, the transformation error was 9.52% which
was caused by students not knowing how to make an equation into the correct mathematical model,
the process skill error was 31.43% which was caused by students not being careful in the process of
solving the problem in carrying out the correct calculations. cause the final results obtained to be
wrong, and errors in writing final answers amounted to 23.81% which was caused by students not
writing conclusions or final answers and also due to incorrect calculations so that the final results
were also wrong.
