Abstract

The aims of this research were to describe the reflective thinking abilities of the students in Grade XII of Vocational High School in Surakarta. This research used qualitative case study approarch. The data of research were tests and task based in interviews. Analysis of the results of written tests and interviews shows that the profile of reflective thinking ability in solving math problems on the content of derivative applications for step by step of the process of mathematization are (1) In solving problems of application of function derivatives at the stage of problem definition, almost all subjects can provide the main problem. (2) In the problem analysis stage, almost all subjects can provide the main problem, but only one subject adjusts the subject matter to the basic formula of flat build. (3) In the criterion stage of the solution, almost all subjects met this stage, even though the results of the evaluation experienced errors. (4) In the information analysis stage, only one subject does not need other information in solving the problem. (5) In the propose solutions stage, all subjects are able to take what I am solving to solve the problem. (6) In the select solution stage, there are some students who can reach this stage. (7) In the implement solution stage, only two subjects reach this stage until completion. (8) In the feedback analysis stage, only two subjects did the re-checking of the steps in solving the problem.
