Errors made by students need to be analyzed further by classifying these errors in certain categories to be directed at correcting more specific errors. This study aims to determine the percentage and causes of errors made by Pekanbaru MAN 1 students in solving acid-base HOTS questions based on Newman's procedure. This type of research is descriptive research with a quantitative approach an…
The application of learning models that are less effective causes students chemistry learning outcomes to be classified as low, so we need a learning model that involves students to be active and independent. In this study, the Blended Learning Flex model was applied which can improve learning outcomes in acid and base materials. The research method used is Quasi Experimental with the Noneq…
This research is motivated by students' understanding of chemical equilibrium material which can be seen from the average score of students' learning outcomes at SMAN 4 Pekanbaru which is not very satisfactory. The purpose of this study was to find out the types and causes of errors made by class XI MIPA students at SMAN 4 Pekanbaru in working on HOTS chemical equilibrium questions based on…
This research is motivated by the need to procure technology-based teaching materials to improve the quality of chemistry learning, in addition to findings in the field that students' reading interest in understanding students' concepts in the material of molecular shapes and molecular interactions is still relatively low.

Progress in the world of information and communication technology has created new opportunities and challenges in the world of education in the industrial revolution era. Articulate Storyline is software that functions as a medium of communication or presentation. Learning media using this software is no less interesting than other interactive media. The Articulate Storyline application is a so…
This research was conducted based on a needs analysis that showed a lack of understanding of students' concepts towards chemical material which is generally abstract so the use of E-LKPD is considered suitable because it can illustrate the chemical processes that occur. The study aims to produce REACT-based E-LKPD using Sway Office on the subject of valid class X SMA / MA chemistry bonds ba…
This research is motivated by various problems faced by lecturers and students in facing the challenges of the 21st century. Knowledge has a role to synthesize the information received. The level of individual success as an educated individual in the 21st century is not only measured by the ability to digest knowledge, but the extent to which individuals are able to use knowledge as a mean…
