Several facts about learning mathematics in high school, show that students' mathematical thinking skills are still low. Therefore, there needs to be an effort to increase these variables, considering that these variables are very important in supporting students' academic achievement. This study discusses the application of a comprehensive mathematics instruction (CMI) model in mathematics learning as an effort to improve students' mathematical thinking. This research is a quasi-experimental research. The sample was taken purposively from the population of high school students in Subang Regency, West Java, Indonesia. The instruments used in the research consisted of a mathematical thinking ability test and an observation sheet. Mathematical thinking ability is built by four important aspects, namely specializing, generalizing, conjecturing and convincing. The CMI model is a learning model that accommodates three stages, namely develop, solidify and practice. Each of these stages provides the opportunity for students to develop specializing, generalizing, conjecturing and convincing aspects. The results showed that the CMI model can improve students' mathematical thinking abilities. Thus, the CMI model deserves to be used as an innovation in mathematics learning.

The need for developing students' higher order thinking skills is the main indicator in the application of HOTS-based questions in high school mathematics learning. The results of the implementation have not shown satisfactory results. The high level thinking ability of students in Indonesia in Mathematics is still very low. Therefore, a HOTS-based diagnostic test is needed which is able to detect the mathematical misconceptions of high school students as the aim of this study. Based on the research objectives, the method of this study is a qualitative method with research design using the Plomp model research design. The subjects of this study were several students and teachers at a school in Cirebon Regency. The results showed that four HOTS questions could be developed based on three aspects, namely, arithmetic, algebra, and geometry. The problem was developed to detect three forms of misconception, namely, theoretical, classification, and correlational misconceptions. The four questions that have been developed were assessed through the readability test of students and teachers, and CVR and CVI tests were carried out on eight mathematics teachers with valid results. Based on these results it can be concluded that the HOTS questions developed can be implemented for students to detect forms of mathematical misconceptions of high school students.

The development of technology today has a huge impact on education, especially in the learning process. Therefore, an educator must be able to adapt the learning process to technological developments. One way to apply technology development in learning systems is to use e-modules in the learning process. The purpose of this study is to use guided inquiry-based e-modules to see the magnitude of the increase in students' critical thinking skills in the material reaction rate after using guided inquiry-based e-modules. The research method used a quasy experiment with a pretest-postest design using two classes as the experimental class and the control class. The sample in this study were students of State Senior High School (SMAN) 1 Sebrida Indragiri Hulu class XI. The results obtained were an increase in students' critical thinking abilities from before the use of guided inquiry-based e-modules. After the use of e-module based guided inquiry. This increase is seen from the comparison between the experimental class and the control cash class. The experimental class using e-module has a higher critical thinking ability of students than the control class that does not use e-module in the learning process.
