. This research aims to improve the chemistry learning outcomes of X.3 students at SMA Negeri 5 Palembang through the TaRL approach. The type of data used is quantitative and qualitative data. Qualitative through direct observation, observation instruments and documentation. Meanwhile, quantitative is obtained through calculating the percentage of pre-cycle, cycle I and II using the criteria for achieving learning objectives (KKTP). Student learning outcomes 4 category: Proficient, Competent, Developing and Needs Guidance.
