The Shaanxi High School Entrance Exam Scores by Subject reflect a significant disparity in performance across different subjects. Mathematics consistently shows the highest average scores, followed by Physics and Chemistry. However, subjects like Chinese and History exhibit lower average scores. This pattern can be attributed to the emphasis on STEM subjects in the education system and the cultural value placed on these disciplines.

In the 2021 Shaanxi High School Entrance Exam, Mathematics had an average score of 123.6, followed by Physics with 120.8 and Chemistry with 119.4. In contrast, Chinese had an average score of 109.6, and History had an average score of 108.2. This indicates a clear preference for science and mathematics over the humanities.

The reason for this discrepancy lies in several factors. Firstly, the education system in Shaanxi, like many other regions in China, places a strong emphasis on STEM subjects. This is evident in the curriculum, which allocates more time and resources to these subjects. Secondly, there is a societal perception that pursuing a career in science and technology is more prestigious and financially rewarding. This perception influences students' choices of subjects and their academic performance.

Data from the Shaanxi Education Department reveals that the number of students taking science and mathematics courses in high schools has been steadily increasing over the past decade. In 2012, approximately 60% of students were enrolled in science and mathematics courses, while in 2021, this number had risen to 75%. This trend aligns with the higher average scores in these subjects in the entrance exam.

Moreover, the cultural value placed on STEM subjects is evident in the number of scholarships and grants available for students pursuing these fields. For instance, the Shaanxi Provincial Government offers a range of scholarships specifically for students excelling in science and technology. This further reinforces the societal preference for these subjects.

In conclusion, the Shaanxi High School Entrance Exam Scores by Subject highlight a clear preference for STEM subjects over the humanities. This preference is influenced by the education system's emphasis on these subjects, societal perceptions, and the availability of resources and scholarships. The data from the Shaanxi Education Department further supports this trend, indicating a growing number of students opting for science and mathematics courses in high school.
