Editor's Note

Critical thinking and creative thinking skills are needed to improve the quality and competitive human resources. Therefore, the application of appropriate learning models is expected to stimulate students' critical thinking and creative thinking skills. This research aims to improve critical thinking and creative thinking skill scores using the ASICC learning model. This type of research is classroom action research which is carried out in 2 cycles, with 3 meetings in each cycle. Data on students' critical thinking and creative thinking skills were collected using essay tests on science learning materials. Data analysis was carried out by comparing the N-gain scores in cycle 1 and cycle 2 for students' critical thinking and creative thinking skills. The results of the research revealed that there was an increase that occurred in cycle 2, namely 5.6% in the aspects of moderate critical thinking skills and high creative thinking, as well as in the aspects of critical thinking skills and high creative thinking by 5.6%. Meanwhile, in the previous cycle, these two aspects did not have a high category. Another result found from this research is that students who have low critical thinking skills do not necessarily have low creative thinking skills. This is because students who have low critical thinking skills may have moderate creative thinking skills or vice versa. Thus, the application of the ASICC learning model is effective in improving the scores of critical thinking skills and creative thinking skills of students at Junior High School 5 Kertosono.

One of the goals of learning physics is to help students develop their critical thinking skills. Preliminary studies conducted at SMAN 1 Pacitan show that the learning process is still teacher-centered with the lecture method and providing practice questions. Such a learning process causes the development of student's critical thinking skills to be less well-stimulated. Using e-modules in physics learning is expected to be a new solution to stimulate students' critical thinking skills. This research aims to determine the impact of Problem-Based learning physics electronic module integrated with STEM on students' critical thinking skills. The research method uses a quasi-experimental technique with a one-group pretest-posttest design. Data analysis used the N-gain test to determine the increase in students' critical thinking skills and the t-test to determine the effect of problem-based learning electronic module integrated with STEM on students' critical thinking skills. The sample was selected using a purposive sampling strategy. The samples involved were 34 students of class XI MIPA Senior High School Pacitan. The test was conducted to collect data on students' critical thinking skills. Research data was collected using an essay test of critical thinking skills totaling twelve valid questions with a reliability coefficient 0.70. Before the N-gain test was carried out, the normality, homogeneity, and t-test were first carried out. In the normality test, the data is normally distributed. In the homogeneity test, the data is homogeneous. Based on the paired sample t-test, it shows that there is a significant difference between pretest and posttest critical thinking skills with a sig. (2-tailed) <0.05, which indicates that the problem-based learning electronic module integrated with STEM has a positive effect on students' critical thinking skills. By acquiring an N-Gain score of 0.76 in the high category, the PBL physics electronic module integrated with STEM on mechanical wave characteristics material can improve students' critical thinking skills.

In 21st-century learning, students are required to develop critical thinking and collaboration skills. Project-Based Learning (PjBL) integrated with gamification is considered a potential approach to support these competencies. This study aimed to examine the effect of gamification-assisted PjBL on Grade X students’ critical thinking and collaboration skills in the biodiversity topic at SMAN 21 Medan. The study employed a quasi-experimental method using a Non-Equivalent Control Group design, involving class X5 as the experimental group and class X7 as the control group selected through random sampling. Critical thinking skills were measured using ten essay questions representing five indicators, while collaboration skills were assessed through an observation sheet based on four indicators. The results showed a significant difference between the experimental and control groups. The t-test analysis of critical thinking skills yielded a significance value of 0.016 (< 0.05), with the experimental group achieving a higher posttest mean score (75.25) than the control group (61.60). Similarly, collaboration skills showed a significant difference with a significance value of < 0.001. These findings indicate that gamification-assisted PjBL has a positive effect on improving students’ critical thinking and collaboration skills compared to PjBL without gamification. Therefore, it is recommended that biology teachers integrate gamification elements such as points, badges, and challenges into project-based learning to enhance students’ critical thinking and collaboration skills.
