ANALISIS KESALAHAN SISWA DALAM MENYELESAIKAN SOAL PERSAMAAN KUADRAT BERDASARKAN TAKSONOMI SOLOPADA KELAS X SMA NEGERI 1 PLUS DI KABUPATEN NABIRE – PAPUA
Abstract: The objectives of
this research were to describe the position of errors, kind of errors and
factor that caused students’ errors in answering quadratic equation questions
based on SOLO taxonomy on the X grade students of SMA with high, moderate and
low mathematics ability. This research was a descriptive qualitative. This
research was carried out on the X grade students of SMA Negeri 1 Plus Nabire –
Papua. The written data were taken from the result of mathematics ability test
and first problem solving test (M1: linear/quadratic pattern) and the second
problem (M2: functional concept), the oral forms data were taken from the
result of interview which were conducted to the subject of the research to get
valid data 1 and valid data 2. Afterwards, the valid data were analyzed to find
out the constant level of consistency achievement of SOLO level, in order to
meet reliable data from the chosen research subjects 2 students with high
mathematics ability, 3 students with moderate mathematics ability and 2
students with low mathematics ability. The valid and reliable data were used to
analyze students’ errors based on SOLO taxonomy. The result of the research
showed that: (a) the students with high mathematics ability were reached
unistructural–relational level, (b) the students with moderate mathematics
ability were reached unistructural–multistructural level, (c) the students with
low mathematics ability were almost reached unistructural level. Errors made by
the research subjects: (1) all of students conducted the same errors in
answering the mathematics model of the quadratic equation questions, they did
not provide the answer correctly and they did not understand the concept of the
questions properly, (2) kinds of errors including: (a) misconception, not
comprehending about quadratic concept, this error existed in all mathematics
ability levels. Whereas errors on the concept of variable, which is used to
form the mathematics quadratic equation, was conducted by moderate and low
level subject; (b) error on the principle, the application of the mathematics
rules and formulas incorrectly in answering the quadratic equation questions,
was conducted by high, moderate and low levels; (c) operational error was often
conducted by low, moderate and high deals with the operational of algebra,
especially on the calculation of negative integer operation, (3) the factors
that caused errors for the research subjects of high, moderate and low levels
were low comprehension on mathematics’ concept, principle and operation.
