A lot of government researchers and administrative staffshave invested a long time to prepare the seventh revision of national education curriculums, and announced it recently for the purpose of growing self-motivated and creative Koreans to live in and lead the global and information era of the 21st century. Reviewing the elective subjects among the curriculums, we can notice that the science subjects for 2ndand 3rd grade high school students fall into the general electives and the specific electives, which consist of various elective subjects, and give the students a wide range of choice without considering their academic sections (of liberal arts or science). However, in the actual situation, the students prefer to choose subjects favorable to good grades for Academic Attitude Test, rather to choose subjects that they like to study. It is commonly noticed that Physics I, II in the elective subjects are most unpopular for the students though necessary to enter science or engineering schools of universities. Changes on the system of entrance exams should be made to encourage students to choose necessary subjects for their future, but modifications on curriculums may help students make right decisions when they choose electives. I, as a researcher who seeks a solution for the above problem, would like to propose some modifications on the system of contents in Physics I, II.First, the concept of vectors that students have difficulties understanding it should be explained importantly in Physics I.Currently, the concept of vectors is explained with details in Physics II. However, a survey tells that 89.24% of the 2ndgrade students in science and engineering sections express their hope to learn vectors before Physics II. According to another survey on appearance of vector quantity in Physics I textbooks, publishing company (A) uses vector quantity by 475 times in 33 pages, and publishing company (B) by 535 times in 37 pages, that is 14 to 15 times per page in average.Second, ambiguity of the atomic model in Physics II textbooks should be fixed. The textbooks show careless description that the Bohr’s atomic model is the modern atomic model while most modern scientists accept the electron cloud model as the modern atomic model. The Bohr’s atomic model has limited meaning that the model became a foundation to lead the next development.Therefore, it is my view that the electron cloud model should have priority than the Bohr’s atomic mode.
