Methods to prevent plagiarism in papers

Academic misconduct such as plagiarism is mainly a matter of study style and teaching style. Although it is unrealistic to completely ban academic misconduct, it can be prevented by strengthening moral self-discipline from internal factors and strengthening education and punishment from external factors. Schools and teachers should attach importance to the academic moral education of students, so that students can form the consciousness of observing academic norms.

Teachers should set an example, abide by academic norms and maintain the academic environment; To severely punish academic misconduct, plagiarists must pay the price for their actions. If there is no punishment, it will only condone the frequent plagiarism. Dr. Xiong Bingqi, a famous educational research expert, believes that the key to prevent plagiarism of dissertations lies in the real tutorial system.
