Chemical bonding was one of the subjects considered difficult by students, because it had submicroscopic concept that learns about the formation of bonds an element that was quite difficult for students to understand. The development of teaching material in the form of teaching materials was seen as a solution to this problem. This study aimed to develop chemical bondinginquiry modelsteaching materials with conflict cognitive strategies towards critical thinking skills. This studywas development research with ADDIE (Analysis, Design, Development, Implementation, and Evaluation)model design. The development results were validated by three expert validators, one practitioner validator and ten IKIP Mataram students as students' limited test validators. Quantitative data from the results of feasibility validation and the results of the assessment of student attitudes toward critical thinking skills were analyzed by percentage formula and the results of effectiveness test data were calculated by N-gain. Qualitative data in the form of responses and suggestions for improvement from the validator was used as a consideration to make revisions to the instructional materials developed. In general, the validator's assessment of the results of the development obtained an average percentage of 83.80%, 85.71%, 88% and 85.71%. While the results of the analysis of effectiveness using the N-gain test obtained an average score of 0.6 with the medium category and analysis. This showed that the teaching materials developed were very feasible to proceed to a broader and more effective stage to foster critical thinking skills.

Student's strategy in solving mathematics problem cannot be separated from the way students receive and process the information obtained which is called as cognitive style. Students have different cognitive styles as they learn. There are students who tend to have a cognitive style of visualizer and there are also students who tend to have a cognitive style of verbalizer. The different cognitive styles will trigger students' critical thinking skills. This research was conducted in Junior High School (Madrasah Tsanawiyah Daru'l Hikam Kota Cirebon) by using the quantitative method of a causal-comparative type. The sampling technique used cluster random sampling, with a total sample of 45 students, 24 students visualizer, and 21 students verbalizer. The results showed that the visualizer students obtained an average score of 50.15, while the verbalizer students obtained a smaller average score of 40.05. When viewed from the average percentage of the results of each aspect of critical thinking, visualizer students can be categorized quite well, while the verbalizer students can be categorized less. Research Results Show that there are differences in critical thinking between students with cognitive style visualizer and students with cognitive style of verbalizer in solving geometry problems
