The profile of student's problem solving skill using analytical problem solving test (apst) on the topic of thermodynamic

Abstract

This study aims to analyze students problem solving skill in solving analytical problem solving test on the topic of thermodynamics. The research approach used is quantitative with descriptive method. The research subjects were 100 students of senior high school in Ngawi. Instrument test research used analytical problem solving test was modified of national examination test. Instrument test in the form of essay test which measure of 4 indicator problem solving skill by G Polya : (1) Understanding the Problem, (2) Devising plan, (3) Carrying out the plan, (4) Looking Back. The results show that percentage achievement of understanding the problem (58.40%), Devising plan (70.92%), Carrying out the plan (65.52%), looking back (42.88%). It shows that the student problem solving skill of senior high school in Ngawi is still moderate category so it's necessary to do improvement effort.
