The problem solving process undertaken by students in solving physics
problems has a different approach pattern. This is reviewed based on the diversity
of students' ability levels in solving problems in learning physics. The purpose of
this research is to describe the approach patterns of students in solving physical
problems in thermodynamic material. This type of research is in the form of
qualitative research using a qualitative descriptive approach. The subjects in this
study were students of grade 11th MIA 3 SMA Labschool UNTAD Palu in the
2019/2020 school year, totaling 20 students and had participated in the physics
learning of thermodynamic material. The instruments used were in the form of
respondents' selection tests, problem solving tests, and interview guidelines. The
respondent selection test contains 24 multiple choice questions with the aim of
capturing respondents in this study. While the problem solving test contains 4
essay questions with the aim to describe the tendency of the approach patterns
used by students in the process of solving physical problems. Respondents in this
study were 6 students. Respondents were selected based on the level of students'
ability which is divided into high, medium and low categories with reference to
the calculation of standard deviations and the average value of students. Then the
respondent is given a problem solving test then the results of the work are
analyzed using a qualitative descriptive approach. In the final stage, the
respondent conducts interview activities. Based on the results of research and data
analysis shows that the ability to solve students' physics problems on
thermodynamic material is in the poor category with an average percentage of
37.33%. As for the pattern of approaches used by students in the physics problem
solving process, they are more likely to use two approaches, namely Structured
Plug and Chug and Unstructured Plug and Chug.
