Analytical thinking skills needed for students in solving problems encountered when learning topic are quite difficult and requires analysis of the issue. Learn to use Learning Start with a Question (LSQ) can help optimize student’s analytical thinking skills. Learning Start with a Question (LSQ) involving active students to seek out and study topic that will be taught. Students learn to solve their own problems in groups and cooperate with each other. Nervous system topic requires analysis of the relationship between the constituent organ tissue structure and associate them with the mechanisms and function disorders that occur in the nervous system topic. This study aimed to determine about effect of Learning Start with a Question (LSQ) on student’s analytical thinking in nervous system topic. The research was conducted in SMAN 33 Jakarta on March 2016. The reseach method used was a quasi experiment with Post Test Only Control Group Design. Subjects in this research were XI IPA 3 as experimental class and XI IPA 4 as control class. A total sample of 64 student was selected by simple random sampling technique. The instrumen used analytical thinking test was  essay. Based the calculation, the average value of the test thinking analysis of the experimental class is 84 and the average value of the test thinking analysis of the control class is 82. Based on calculation, prerequisite test analysis data obtained was not normally distributes but homogeneous. The statistical hypothesis with Mann-Whitney test result on accepted null hypothesis at α 0,05. It showed that there was no about effect of Learning Start with a Question (LSQ) on student’s analytical thinking in nervous system topic.

The Science, Technology, Engineering, and Mathematics (STEM) approach has become an interesting research object. Several studies have proven that the STEM approach has overcome various learning problems. It involves many teaching and learning aspects, either the cognitive, affective, or psychomotor domains, positively affecting the students' learning outcomes. This study aimed to describe the effect of the STEM approach with the Brainstorming method on critical thinking and creative thinking skills of students in physics learning. This study employed quasi-experimental research with a non-equivalent control group design. The sampling was done through the simple random sampling technique with a total sample of 60 high school students. The instrument used in this study was an essay test instrument to measure critical thinking and creative thinking skills. The Multivariate Analysis of Variance (MANOVA) was used as the research hypothesis testing technique. The results showed that the significance score of critical thinking skills was 0.001, and the significance score of creative thinking skills was 0.019. So, it can be concluded that the application of the STEM approach with the Brainstorming method is effective in improving students' critical thinking and creative thinking skills in learning physics, both through multivariate tests and separate tests.
