The integration of 21st-century learning and generic science skills (GSS) is critical in developing students' higher-order thinking skills (HOTS), especially in chemistry education. This quasi-experimental study aimed to analyze the effects of implementing four GSS-integrated digital learning models (PjBL-GSS, PBL-GSS, IBL-GSS, and DL-GSS) and students’ initial abilities on their HOTS performance. A total of 397 students participated, grouped by initial ability levels and assigned to different learning models. Data were collected using validated instruments including scholastic tests and HOTS assessments, and analyzed using descriptive statistics and two-way ANOVA. The results showed significant effects of both initial abilities and learning models on HOTS, with IBL-GSS being the most effective, especially for high-ability students. Moreover, significant interactions were found between initial ability and the type of model used. The study suggests that selecting appropriate digital learning models based on students' prior knowledge is essential to foster optimal HOTS outcomes. Teachers are encouraged to align instructional design with both GSS indicators and students’ learning readiness.

The low ability of students to think critically in chemistry learning, especially in thermochemistry materials, is still a problem that needs attention. This is due to learning that tends to be teacher-centered and the use of teaching materials that have not encouraged active student involvement in problem solving. Therefore, this study aims to determine the effect of the use of problem-based textbooks on students' critical thinking skills and responses to thermochemistry learning. The method used was a pseudo-experiment with a two-group pretest-posttest design accompanied by a student response questionnaire. The experimental class used problem-based textbooks with the Problem-Based Learning (PBL) model, while the control class used school textbooks with the Direct Instruction model. The research instruments were in the form of critical thinking ability tests and student response questionnaires. Data analysis was carried out through hypothesis and N-Gain tests. The results showed that the use of problem-based textbooks had a significant effect on students' critical thinking skills (sig. 0.017 < 0.05). The average posttest of the experimental class of 81.77 was higher than that of the control class of 76.57. The N-Gain value of the experimental class was 0.747 in the high category, while the control class was 0.697 in the medium category. The increase in critical thinking skills in the experimental class occurred in all indicators, namely building basic skills by 0.851, providing simple explanations by 0.810, concluding by 0.736, making further explanations by 0.736, and strategies and tactics by 0.616. Students' responses to learning are in the very positive category. Thus, the use of problem-based textbooks is effective in improving students' critical thinking skills on thermochemical materials.
