The mind mapping model can make students think critically and convey as much information as possible. The use of technology-based Mind Mapping learning models is still not widely applied in schools; teachers tend to still use manual methods, memorizing, and giving assignments, so that students are less enthusiastic or interested in the learning process. The purpose of this study is 1). Knowing the application of technology-based Mind Mapping learning models in ICT learning, 2). Assessing students' critical thinking skills in the application of the Mind Mapping learning model, 3). Assessing the influence of technology-based Mind Mapping learning models on students' critical thinking skills in terms of gender. The results of the study show that the mind mapping method can increase students' average scores by up to 25% within two learning cycles. The method used is descriptive analysis using pre-test and post-test, which are then further analyzed using Microsoft Excel data analysis to test validity, normality, T-test, and Shapiro-Wilk test to see the effect. Based on the results of the correlation test, the results were 0.548 while the r table value was 0.361, so it can be concluded that 0.548> 0.361 means there is a relationship between the two. Based on the results of the correlation test of 0.548, it is in the high or strong relationship category. It can be concluded that the criteria for the strength of the relationship between pretest and posttest learning outcomes show a very strong relationship, which indicates a significant increase in students' critical thinking skills after participating in the mind mapping method-based learning process. This reflects the effectiveness of the mind mapping method applied and provides an impact on critical thinking in the Tik lesson on the ethics of social media use by students.
