The main objective of this study was to improve writing skills of balanced chemical equations using chemical symbols of elements and formulas for ten 2nd Year integrated Natural Science extension trainees. Participants were selected using a purposive sampling method. The tools used in data collection were observation, document analysis, questionnaire, test, and interview. The data collected by these tools were analyzed by qualitative and quantitative analysis methods according to their characteristics. According to this study, the participants had very little understanding of the symbolic language, which is very important for learning chemistry. Therefore, to solve this problem and to fill the gaps, the researcher had to set special tutorial and counseling programs to improve their skills. After the plan was implemented, all the study participants' skills in chemical symbol identification, writing formulas, and balanced chemical equation improved except for one trainee.
