abstract={This research aimed to analyze the gain of students¡¯ critical thinking and problem solving ability by using conventional learning; to analyze whether the gain of students¡¯ critical thinking and problem solving ability by using problem based learning model better than conventional learning. This research was a quasi experimental research with two group pretest-posttest design. The population of this research was second semester of State Senior High School 1 class X academic year 2016/2017.The sample of this research were two classes that consisted of 70 students by using cluster random sampling technique. Class X MIA-1 as experimental class taught by problem based learning model that consist of 34 students, class X MIA-2 as control class taught by conventional learning that consist of 36 students. The instruments of the research were essay test of critical thinking ability and problem solving ability that consist of 5 questions for each. The data were analyzed by using t-test statistics. The results showed that: the mean gain of students¡¯ critical thinking and students¡¯ problem solving ability taught by problem based learning was in medium level and the mean gain of students¡¯ critical thinking and students¡¯ problem solving ability taught by conventional learning was in low level. Hypothesis test showed that the mean gain of students¡¯ critical thinking and problem solving ability taught by problem based learning was better than conventional learning, this result showed that there was an effect of problem-based learning model on students¡¯ critical thinking and problem-solving ability.},
