This study aims to determine the categories of validity and practicality of the e-modules that have been produced. The type of research is classified as a 4-D model, which has four stages, namely the define, design, develop, and disseminate stages. The instruments used are a validation sheet and a practical sheet in the form of a questionnaire sheet. The resulting product was tested for validity by 5 validators, consisting of 3 lecturers majoring in chemistry at FMIPA UNP and 2 teachers from SMAN 1 Rao, Pasaman Regency. Practicality tests were carried out by 2 chemistry teachers along with 15 students in class XI MIPA SMAN 1 Rao, Pasaman District. Based on the validation results, the value of kappa moment (k) is 0.86. The practicality of teachers and students is then obtained by the average value of kappa moment (k) of 0.90 and 0.88. The value obtained indicates that the resulting e-module is categorized as very valid and practical.

HOTS is an ability that can transfer, connect one material with other material, process information and solve problems obtained from the information creatively and critically. Higher Order Thinking Skill (HOTS) are abilities that must be prossessed by students in facing global competition in the 21st century industrial revolution 4.0 in accprdence with the 2013 curriculum. This study aims to produce a test instrument for higher order thinking skill (HOTS) in chemical equilibrium and determine the level of validity and its reliability. This tyepe of research is research and development (R&D) and use the research model that has been developed by treagust (1988). The results showed that the value of the validity of the content instrument test was 1 and the validity of the construct instrument was 95% in the material aspect, 94% on the presentation aspect, 96% on the language aspect, and 08% on the additional rules. The instrument reliability tes coefficient is 0,85 for the question (fisrt tier) and 0,89 for the reason (second tier).

Most of the topics discussed in chemistry are abstract, meaning that the concepts studied do not appear concrete. E-modules are learning media that can be presented using multiple chemical presentations to present abstract material, one of which is electrolyte and non-electrolyte solution material. The aim of this research is to produce a valid e-module of electrolyte and non-electrolyte solutions based on contextual teaching and learning. The validity value will be obtained by using the Aiken’s V formula. This research used Educational Design Research type with Plomp as the development model. The average value of Aikens' V obtained is 0.892 for content validity, 0.896 for construct validity and 0.893 for expert validity, so that this e-module is stated to include category learning media that is already valid to be used during the learning process.

This research was conducted to continue previous research on the development of guided inquiry-based chemical equilibrium e-modules that have been tested for validity and practicality, but have not yet been tested for their effectiveness. The purpose of this study was to determine the level of effectiveness of the GIL-based chemical equilibrium e-module equipped with a practicum video that had been developed on the learning outcomes of class XI students of SMA N 1 Payung Sekaki. This research uses Pre-Experimental Design with One Group Pretest-Posttest design. The population includes students of class XI IPA 1 SMA N 1 Payung Sekaki in the academic year 2021/2022 and the sample is taken using a saturated sampling technique. Until l cover the entire population. This study uses a test instrument in the form of objective questions with validity, reliability, difficulty index, and discriminating power of questions that have good criteria. The level of effectiveness of the guided inquiry-based e-module equipped with a practicum video can be known after the N-Gain test is carried out. The N-Gain analysis on the sample class gave the results of the value of g = 0.58 in the medium category. This shows that the use of e-modules as a substitute for guided inquiry-based chemicals equipped with practical videos is effective in improving the learning outcomes of class XI students of SMA N 1 Payung Sekaki.

ABSTRACT One of the determining factors for the success of learning in the classroom is the use of learning media that can help educators convey messages and subject matter to students effectively and efficiently. Based on the questionnaire analysis, SMAN 16 Padang and SMAN 1 Gunung Talang, information was obtained that most of the class XI students said that the difficulty in understanding chemistry lessons was one of the reasons for the limited use of teaching materials. Therefore, the purpose of this study is to produce teaching materials in the form of REACT-based acid-base Student Worksheets (LKPD) for class XI Senior High School which are valid and practical and to determine the level of validity and practicality of the REACT-based acid-base worksheets that have been developed. The method used in the development or Research and Development (R&D). The results of this study are REACT-based worksheets on acid-base materials for class XI Senior High School developed through a 4-D development model with the stages of define, design, develop, and disseminate. Valid and practical LKPD.

Chemistry is a branch of natural science that is closely related to everyday life. Until now, it is mandatory to learn at the high school level is chemistry subject matter of chemical equilibrium. Chemistry lessons at this time tend not to be of interest to students because they are considered difficult. Based on data from interviews with several chemistry teachers at SMA 14 Padang, the material for chemical equilibrium was still difficult for students to understand, where learning at school was still teacher-centered. The solution is to apply the LSLC-based GDL model to encourage active students and improve quality and improve the course of a learning process. this type of research is quasi-experimental. the results of the research data are normally distributed and homogeneous, so the hypothesis test that is carried out is the t-test with 0.03 < 0.05. That is, the learning outcomes with chemical equilibrium material for students who were given treatment using the LSLC-based GDL model were higher than the learning outcomes of students who applied the GDL model without LSLC.

The selection of learning models that have not been carried out optimally by educators so that a learning system is needed that supports this learning model. One learning system that can be applied is a lesson study-based learning system for learning communities. The key to the implementation of lesson study for learning community is in the reflection (see) stage so that the learning process has increased and has an impact on increasing teacher competence and improving student learning outcomes. The purpose of this study was to reveal the effect of the guided inquiry learning model based on lesson study for learning community on salt hydrolysis material on student learning outcomes of SMAN 10 Padang. This research is a quasi-experimental in the form of nonequivalent control group design. The analysis carried out obtained the results of data that were normally distributed and the variance was homogeneous so that it fulfilled the requirements of the t-test and obtained a sig(2-tailed) value of 0.001 < 0.05. Based on data analysis, it was concluded that the guided inquiry learning model based on lesson study for learning community on salt hydrolysis material has a significant effect on student learning outcomes.

This research is based on the limitations and monotony of learning resources in schools and the gap between educational practices and the character of students in schools. There is a need for learning resources that can be used as a solution to this gap. The purpose of this research is to develop an ethnoscience-based E-ChemMagz edition of reaction rate material to improve student character that is valid and practical. The research used the EDR (Education Design Research) research method with the utilization of the Plomp model. There are three stages carried out from this development, namely preliminary research, development (Development/Prototype) and assessment (Assessment phase). The instruments used in this study were validity and practicality sheets. From the final results of the study, it shows that the learning resources supporting the ethnoscience-based E-ChemMagz edition of the reaction rate are valid and practical. The data obtained from the developed product shows a V value of 0.87 with a valid category. The E-ChemMagz practicality test obtained a very positive response, with a percentage of 92.15% teacher response and 91.03% student response, each of which was classified as a very practical category used in learning.
