Abstract

Mathematics is an important field of study that is taught at various
levels, one of them is college. To become a Bachelor of Mathematics
Education, one of students' mathematics skills can be seen in the ability
to solve problems. This study aimed to find out the error of Mathematics
Education students in solving Differential Equation problems based on
Watson's criteria, and find out the factors causing the error to occur.
This research is important to do to find out the errors in solving
Differential Equation problems and the factors causing the error to
occur. The research design and approach of this research was
Descriptive Qualitative. Data was obtained through written test
instruments, interviews and documentation. The analysis technique
used to analyze student error was based on Watson's 8 criteria, while
the research data analysis were data reduction, data presentation and
drawing conclusion. The results found that the percentageof
inappropiate data (28.11%), inappropiate procedure (24.32%), omitted
data (27.57%%), omitted conclusion (84.86%), response level conflict
(2.16%%), undirected manipulation (4.86%), skill hierarchy problems
(6.49%), and above others (64.32%). The percentage of error that
occurred in 37 students from all questions based on Watson's 8 criteria
was 30.34%. Factors that cause errors are: (1) internal factors,
students do not fully remember the material being tested, they have not
mastered the material tested properly and are not thorough when doing
the test; (2) external factors, students do not focus when doing the test,
work together with friends, and incomplete notes.
