The purpose of this study is to produce an electronic module using IBL integrated model HOTS in 21st century of Physics learning class X with valid and practical criteria. The thinking ability of students in learning physics is still not in accordance with the thinking skills that are needed in the 21st century. One of the reasons is because of the modules used by students still do not contain model steps that are integrated with the level of thinking skills. This type of research is a development research using the ADDIE model which consists of five phases, those are Analysis, Design, Development, Implementation, and Evaluation phase. Which in this research only carried out the development and implementation phase. The research instrument included are a validity questionnaire and practicality questionnaire. Data analysis techniques for validity used the Aiken’s V formula and for practicality using descriptive percentages. The results of the development stage show that the electronic module has an Aiken’s V value of 0.86 with the valid category. The results of the implementation stage show that the practicality of the electronic module is in the very practical category with a value of 93.27% for teacher responses and 87.86% for student responses. Thus, it can be concluded that the module electronic using IBL model integrated HOTS in the 21st Century Physics Learning of Class X meets the criteria of being valid and practical. The results of the implementation stage show that the practicality of the electronic module is in the very practical category with a value of 93.27% for teacher responses and 87.86% for student responses. Thus, it can be concluded that the module electronic using IBL model integrated HOTS in the 21st Century Physics Learning of Class X meets the criteria of being valid and practical. The results of the implementation stage show that the practicality of the electronic module is in the very practical category with a value of 93.27% for teacher responses and 87.86% for student responses. Thus, it can be concluded that the module electronic using IBL model integrated HOTS in the 21st Century Physics Learning of Class X meets the criteria of being valid and practical.

Physics learning activities have not been carried out optimally as seen from the low competency of students’ knowledge. This is due to the lack of available teaching materials that fit the needs of students, the available teaching materials are very limited because they do not take advantage of technological developments and there is no model in them, so learning is not entirely student centered. Utilization of technology is one of the efforts to facilitate learning in accordance with the needs of students by developing non-printed teaching materials in the form of interactive student worksheet based on inquiry based learning models. The purpose of this research is to produce an interactive student worksheet based on a valid inquiry based learning model. This type of research is research and development using the ADDIE model. The method used in this research is descriptive statistics. The validity of the interactive student worksheet is assessed by three experts using a validity questionnaire. The validity of the interactive student worksheet is analyzed using the Aiken’s V. formula. The validation results show that the material validity aspect is 0.87; visual display 0.89; and learning design 0.85. Based on the analysis of the validity of interactive student worksheets data, an average of 0.87 is in the valid category. Thus, Interactive Student Worksheets based on inquiry based learning model can be implemented in physics learning to increase knowledge competence.
