Industry 4.0 Revolution is an era in human life that is developing at this time, where in this era human life is oriented to technology. Mastery of technology today is a challenge for humans to make life easier. In this era also more human resources will be replaced by machines and technology. The industrial revolution 4.0 also influenced the education sector, for example in the development of teaching materials. Teaching material is one of the learning resources that can help students in the learning process so as to improve the competency of students. The teaching materials needed must lead to the development of technology that can facilitate students in learning. One example of teaching materials that are currently developing is the e-module. E-modules can help students understand physical concepts. It is hoped that with the help of physics guided E-module based on Guided Inquiry can improve the critical thinking skills of students in understanding physics. The ability to think critically is one of the characteristics of the 4.0 industrial revolution in education. The purpose of this study is to identify the critical thinking skills of high school students with the help of e-module based on Guided Inquiry. This type of research is quantitative descriptive with an instrument in the form of an observation questionnaire given to students and educators. Based on the results of observations given there are teaching materials that have not been oriented to the critical thinking skills of students. Therefore it is necessary to do an analysis in the development of physics guided e-module based on Guided Inquiry to improve the critical thinking skills of high school students.
Today’s technology is developing very rapidly, marked by many latest sophisticated inventions in various fields, including in the educations sector. The application of technology in the education field is found by electronic-based learning media such as the E-module. However, the existing E-module has been not able to guide a student to find physics concepts and according to the needs and conditions of students. So, it’s necessary to develop a guided inquiry-based e-module integrated ethnoscience that fits with the needs and conditions of students. This research is descriptive qualitative research. The result of media analysis, guided inquiry-based E-module are needed that suitable the needs and conditions of students.
Teachers in learning in junior high schools use teacher books. In conducting the learning process and the use of student books, the teacher is guided by the teacher’s book. So that the teacher’s book is appropriate for use in learning, the book should be valid. This study aims to determine the validity of the blood fluid teacher’s book using connected type learning integrated learning in the 21st century. This research uses Plomp model development research, while the validation process is carried out in the development phase. Validity data is obtained by using a validity questionnaire. Data were analyzed with a Likert scale and validation values were calculated by the Aiken formula. The results of the teacher validation analysis developed were obtained the book with valid criteria. From the results of the analysis it can be concluded that science teacher books are integrated the theme of blood fluid through learning connected type integrated 21st century skills worthy of being used in the learning process.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
