Abstract
This study aims to analyze the content of the 10th-grade chemistry textbook in the second year of senior high school education based on the Plesk creativity pattern. The research method is descriptive, employing quantitative content analysis. The statistical population includes the 10th-grade chemistry textbook for the academic year of 2023-2024. Given the nature of the study, sampling was not conducted, and the entire content of the textbook, including texts, tables, images, and end-of-chapter exercises were analyzed. The opinions of three experts were used in the form and content validity of the content verification checklist. The reliability of the tool was established using Holsti Index. The reliability coefficient obtained from this index was 0.83. Data analysis was performed using the Shannon entropy method. The results indicate that from among the three principles of the Plesk pattern, ‘Escape’ and ‘Attention’ rank first and second in emphasis, respectively. The ‘Movement’ principal lags significantly in third place. Components related to the ‘Attention’ principle, such as attracting attention, purposeful observation, and concept extraction are evenly distributed. In the ‘Escape’ principle, components like flexibility and attention to detail are well-covered, but magnification, minimization, and inversion receive less emphasis. Based on the importance coefficient calculated using the Shannon entropy method, ‘Purposeful Observation’ holds the highest importance, followed by ‘Combination’ and ‘Attention Attraction’. In contrast, components like substitution, magnification, minimization, and inversion have the lowest attention in the textbook's content analysis. Therefore, the 10th-grade chemistry textbook lacks the necessary balance in addressing the principles of the Plesk creativity pattern, indicating the need for revision to ensure more equitable attention to these components.
