Enhancement Student Achievement on Basic Chemistry Course Through Assessment as Learning Implementation

This paper described student achievement on Basic Chemistry Course through assessment as learning implementation. The research method used one shot case study. Matter of Basic Chemistry Course consist of Stoichiometry, The Periodic Table and Chemical Bonding. The first implementation in the research was assessment as learning implementation on Stoichiometry Matter, then on the Periodic Table Matter and the last on Chemical Bonding Matter. The end of each implementation, students were given assessment. Based on result of assessment, student reflected his/her achievement to enhance their learning. The material learning consist of Lesson Plan, Worksheet and Guiding Book. Instrument of research was Sheet of Student Achievement Test. Based on result of research showed 89.7% of students tended to enhance and 10.3% students tended to go down in student achievement.
