Nowadays, the process of teaching and learning to write was conducted
unsuccessfully for several reasons. Some of them hampered on students’ language
competence such as content, vocabulary, grammar, etc; however, only a few
research studies investigated how the students’ ways to plan, react, and solve
problem faced in their learning. Therefore, the writer was interested to prove her
hypothesis and conduct a correlation study in order to investigate whether
vocabulary mastery and reflectivity jointly together influence writing skill. The
research was conducted at SMAN 10 Tangerang. The method of the research was
a correlational study. The writer used a probability random sampling. 73 students
out of 297 students of the eleventh grade in academic year 2016/2017 were
