In designing a lesson, a lecturer need to consider what material should be taught, and how is the appropriate method to teach, and how to make sure that all students will learn the subject. Struktur Aljabar I is one of mathematic pure proficiency material at Mathematic departement. the characteristic of Struktur Aljabar has tight and cronological axiomatic deductive structure, full of abstract concept in definition or theorem. Therefore, Struktur Ajabar is difficult to learn and difficult to taught. that is why learning material and teaching activity is needed tobe directed in order to help the student to understand the link between the concepts, managing their own self learning, cooperating, and critical thinking. The aim of this study is to develop learning material by using REACT strategy at Struktur Aljabar I subject. This developing and trial research consist of design, limited trial application, and data analysis. descriptive analysis was used, and this research development produced a protoype Struktur Aljabar I material REACT base. Keywords: development, learning material, REACT strategy, Struktur Aljabar I

The lesson plan is very important to be mastered by the teacher to be able to carry out learning in the classroom to be directed. The lesson plan also contains a question instrument as an assessment of the achievement of learning indicators. The questions compiled must contain high-level thinking-based questions in this 4.0 century. However, in reality, many teachers have difficulty compiling lesson plans with high-level thinking questions. Student teacher candidates also have not been able to design high-level question-based questions. This study aims to see the effectiveness of mathematical literacy in planning student mathematics learning based on HOTS. This research is qualitative research using research methods in the form of data analysis of research results about HOTs that have been designed, interviews, and documentation. The results of this study indicate that the average value of students in planning HOTs-based mathematics learning is 85.7%. Then based on the HOTs-based learning planning that has been designed, 77.8% of students have been able to design questions and their answers by applying questions in everyday life and designing open-ended questions.

This study aims to develop a mathematical assessment instrument for senior high school students based on higher order thinking skills (HOTS). This research is development research that aims to develop a valid, practical and effective HOTS assessment instrument. The development model used is the Tessmer’s model. There are five steps applied in this study, namely preliminary, self-evaluation, expert review, one-to-one and small group and field testing. The research findings explained that each item met the validity of content (content), construct, and language. Content validity is the compatibility between the questions and the indicators that have been set for each material. Fulfilling construct validity refers to the instrument measured by the HOTS concept. It met the validity of the language because the sentence structure in the question followed the correct Indonesian language rules and did not contain double meanings or ambiguity. Therefore, this item is appropriate to be used as an alternative teaching material for students to develop their higher-order thinking skills, especially in the material about flat-plane analytical geometry.
