The research type was quasi experiment and two group pretest-posttest designs were used in this study. The sample were Class XI(A) as experiment class and Class XI(B) as control class with the total number sixty two students. The instruments in this research were essay test for physics cognitive competence of students and observation sheet for science process skill of students. The essay instrument had been validated and fulfilled the requirements of validity and reliability of test. Based on the data tabulation obtained, the mean of physics cognitive competence of students in experimental class was 72.97 and 54.97 in control class, the mean of science process skill of students in experimental class was 79.66 and 63.97 in control class. Based on the hypothesis testing, it can be concluded that physics cognitive competence and science process skill of students using scientific inquiry learning model based on conceptual change was better than using conventional learning 1. Introduction Studying physics does not only focus to the facts, law, theory, principle, models, and mastery the formulas but also focus to understand the basic concepts. Concepts are abstract or psychological constructs represent ideas that a learner uses in reasoning and thinking. They constitute the general tools of inquiry used in making sense of the world and are the most significant influence in learning. In Physics, Learner's existing concepts are known to have a profound influence on how phenomena is interpreted, and learners draw on these concepts in making predictions and explaining what they see and experience in the world (Heywood &Parker, 2019). Studying physics also requires more than just learning about the products of science like concept. The culture of science involves very special actions called science process skill. The science process skills describe the actions or active doing within the culture of science that students can develop through practice and provide benefits to the classroom that extends beyond science learning. Thus, Teachers, in terms of supporting their students' science learning are challenged to achieve a balance between science concepts and process skills. Based on the observation and interview result from Physics teacher at SMA Muhammadiyah 1 Medan Nort Sumatera Indonesia obtained, students' learning outcomes in cognitive domain was still in low level because they are still less ability to solve the problems related to the physics concept and they are mostly concerned to the formula and calculation. Thus, students felt so difficult to apply what they have known in their daily life situation. This was indicated from physics means grades of students before remedial in academic year 2014/2015 with grade 69, this average value has not achieved the standard grades, that is 70. Moreover, students science process skill is also in low level which is indicated from the unusual of students to conduct experiments in learning physics, meant learning physics just theoretically. Besides, learning which familiarized conducts by teacher are direct instruction and cooperative learning where methods are lectured, discussion, investigation, and mapping concept. But, all these models have not conducted as the phases of each model. This condition make students have not familiarized to find knowledge by themselves through scientific inquiry, thus students cannot provide explanations based on evidence. Most of student's difficulties in learning physics are not caused by lacking of their understanding because they often come to school with already formed ideas on many topics, including how they view and interpret the world around themselves. Students have ideas about the world that are very different from the ideas of scientists which delivered in the class. Thus, teacher needs listening to how learner explain their understanding because that's not possible that their ideas are certain logics, therefore it is inappropriate to dismiss their thinking as errors that simply need to be corrected. Furthermore, teacher needs to develop learning that would move learners away from their initial ideas so they became aligned with accepted scientific explanations. This label suggests that students are using evidence to support their explanation and that way is consistent with the actions within the culture of science. This kind of learning is called as conceptual change.

The research type was quasi experiment and two group pretest-posttest designs were used in this study. The sample were Class XI(A) as experiment class and Class XI(B) as control class with the total number sixty two students. The instruments in this research were essay test for physics cognitive competence of students and observation sheet for science process skill of students. The essay instrument had been validated and fulfilled the requirements of validity and reliability of test. Based on the data tabulation obtained, the mean of physics cognitive competence of students in experimental class was 72.97 and 54.97 in control class, the mean of science process skill of students in experimental class was 79.66 and 63.97 in control class. Based on the hypothesis testing, it can be concluded that physics cognitive competence and science process skill of students using scientific inquiry learning model based on conceptual change was better than using conventional learning 1. Introduction Studying physics does not only focus to the facts, law, theory, principle, models, and mastery the formulas but also focus to understand the basic concepts. Concepts are abstract or psychological constructs represent ideas that a learner uses in reasoning and thinking. They constitute the general tools of inquiry used in making sense of the world and are the most significant influence in learning. In Physics, Learner's existing concepts are known to have a profound influence on how phenomena is interpreted, and learners draw on these concepts in making predictions and explaining what they see and experience in the world (Heywood &Parker, 2019). Studying physics also requires more than just learning about the products of science like concept. The culture of science involves very special actions called science process skill. The science process skills describe the actions or active doing within the culture of science that students can develop through practice and provide benefits to the classroom that extends beyond science learning. Thus, Teachers, in terms of supporting their students' science learning are challenged to achieve a balance between science concepts and process skills. Based on the observation and interview result from Physics teacher at SMA Muhammadiyah 1 Medan Nort Sumatera Indonesia obtained, students' learning outcomes in cognitive domain was still in low level because they are still less ability to solve the problems related to the physics concept and they are mostly concerned to the formula and calculation. Thus, students felt so difficult to apply what they have known in their daily life situation. This was indicated from physics means grades of students before remedial in academic year 2014/2015 with grade 69, this average value has not achieved the standard grades, that is 70. Moreover, students science process skill is also in low level which is indicated from the unusual of students to conduct experiments in learning physics, meant learning physics just theoretically. Besides, learning which familiarized conducts by teacher are direct instruction and cooperative learning where methods are lectured, discussion, investigation, and mapping concept. But, all these models have not conducted as the phases of each model. This condition make students have not familiarized to find knowledge by themselves through scientific inquiry, thus students cannot provide explanations based on evidence. Most of student's difficulties in learning physics are not caused by lacking of their understanding because they often come to school with already formed ideas on many topics, including how they view and interpret the world around themselves. Students have ideas about the world that are very different from the ideas of scientists which delivered in the class. Thus, teacher needs listening to how learner explain their understanding because that's not possible that their ideas are certain logics, therefore it is inappropriate to dismiss their thinking as errors that simply need to be corrected. Furthermore, teacher needs to develop learning that would move learners away from their initial ideas so they became aligned with accepted scientific explanations. This label suggests that students are using evidence to support their explanation and that way is consistent with the actions within the culture of science. This kind of learning is called as conceptual change.
