Improving Science Communication Skills Using Worksheets Based on Think-Talk-Write

Science communication skills are the process of conveying information or data from observations or experimental results to be known and understood by others. Student worksheets are printed teaching materials in the form of guides for carrying out an investigation or problem-solving activities concerning the basic competencies that must be achieved and are intended to streamline learning and help students master understanding, skills, and attitudes. Student worksheets developed in this study think talk write (TTW) based student worksheets. This study aims to determine the effectiveness of TTW-based student worksheets in improving science communication skills. The research method used was an experimental design with a randomized control group pre-test post-test. Data collection was done by giving 18 items of pre-test and post-test. Data analysis was performed using the N-Gain test and one-tailed t-test. Based on the results of this study, it was found that an increase in the results of the N-Gain test was 58.68%, while the results of the one-tailed t-test showed that the TTW-based student worksheets could help students improve their science communication skills
