The ability of analytical thinking and scientific attitudes in the process of learning chemistry requires learning models that can enhance analytical thinking related to scientific attitudes used by students to solve complex and unstructured problems in the 21st century. Thus, this study aims to determine the ability of analytical thinking and scientific attitudes of high school students in learning chemistry. This study was carried out using a quasi-experimental with post-test only design. This research was conducted in senior high school in the rate reaction topic. The sample in this study consisted of two classes, namely Class XI Science 1 as an experimental class with a problem based learning model and Class XI Science 3 as a control class with direct instruction. A total of 63 students of class XI were determined as research samples and the sampling was done by random sampling techniques. The instrument used was a test in the form of essays and non-tests used in this study were students’ scientific attitude questionnaire. The MANOVA test was used to analyze differences in the abilities of analytical thinking and scientific attitudes of students in the experimental class and the control class. The results of this study indicate that the value of sig <0,05 ie 0,000 <0,05 is thus the application of the problem based model to the analytical thinking abilities and scientific attitudes of students of senior high school on the rate reaction topic.
