Because the basic election principles are fundamental in democracy, they need to be taught exactly and precisely. Current high school Law and Politics textbooks deal with the four principles of universal suffrage, equal election, direct election, and secret ballot. But they must also treat the principle of free election, which means freedom of decision by all election participants, such as the electorate, candidates, and political parties. Furthermore, current textbooks must add the following facts to the four election principles: universal election regardless of occupations, religions, and taxation; equal opportunity in election itself in equal election; prevention of specific agencies' follow-up distortions of electoral results in direct election; and secret election before and after balloting. To effectively learn the basic election principles, it is necessary for students themselves to learn the principles by exchanging their opinions through simulation learning. Also, students need to understand the principles more clearly by analyzing examples of various kinds of rigged elections. In particular, they need to examine how specific rigged election cases have violated specific principles.
