Introduction:
According to findings in the investigation report, most of key
stage 4 students have little knowledge about sex education. Thus, providing
knowledge such as: sex transmitted diseases, birth control, and sex education
article are important. Therefore,
Article feature is developed in order to provide knowledge about sex
transmitted diseases (STDs), birth control and sex education article by
experts. As a result, it will help key stage 4 students have enough knowledge
to understanding themselves and others.
