This review aims to describe the model, characteristics, and design of blended learning, to describe the trend of research blended learning in supporting the development of students' mathematical thinking skills and to provide recommendations for blended learning in supporting the development of students' mathematical thinking skills in the future. The method used in this paper is an article review method which is carried out in three stages, namely identifying keywords related to blended learning in developing mathematical thinking skills, article search strategies, and analyzing articles. Blended learning is a combination of learning patterns, between face-to-face learning and online learning. The trend of Blended learning is carried out with online learning and face-to-face learning in class is carried out alternately (rotational model), using various LMS. The results of the article analysis show that the blended learning stage can develop students' mathematical thinking skills, namely the seeking of information stage students are directed to think critically. At this stage students are more motivated and independent in finding or accessing materials online. Then at the stage of acquisition of information and synthesizing of knowledge, students are directed to solve problems, use mathematical understanding skills, reasoning, connection and representation skills, communication and collaboration, and think critically through discussions, presentations, and work on practice questions. In addition, students look more enthusiastic and motivated because it is adjusted to their learning style and learning speed and students are directed to be independent in learning the material. The researcher recommends a blended learning design using the flipped classroom model with online learning using the Moodle LMS in which each stage of blended learning, students are directed to rely on mathematical thinking skills. Keywords : Blended learning and mathematical thinking skills

This study aims to develop online learning tools in the Algebra Structure course. This research is a development using the Kemp model. The learning tools produced in this study are RPS, RTS, teaching materials, learning videos and learning outcomes tests. The results of the validation and testing of the learning tools show that learning tools are valid, practical and effective. The average validator's assessment of the RPS, RTS, Teaching Materials, Learning Videos and Tests Learning outcomes are 3.72, 3.76, 3.76, and 3.72 with good criteria. The average value of observations by observer 1, observer 2 and observer 3 is 4.00, 4.06, and 4.12, with good categories. The results of student responses showed that 93.482% of students satisfied with the teaching component, 84.09% of students satisfied with the novelty of the learning component, 94.87% interest in participating in further learning, 88.88% expressed satisfaction with language clarity, 91.42% satisfied with the appearance of the material teaching and learning videos. The validation of the questions showed that there were 3 items with high validity, and there were 6 items with sufficient validity. Furthermore, the test reliability coefficient = 0.79 which indicates that the learning outcomes test has high reliability and is used without revision. Thus, the validation and testing of the device shows that student activities are effective, lecturers' ability to manage learning is good, student responses are positive and test results are valid and reliable.

This research is a descriptive study with a qualitative approach that aims to describe the mathematical literacy ability of students with kinesthetic learning styles. The subject in this study was a fifth-grade elementary school (SD) student with a kinesthetic learning style. Data were collected using documentation, interviews, and observation. Data analysis techniques used in this research are data reduction, data presentation, verification, and decision. This study gives the results that: (1) the level of mathematical literacy ability of the research subjects is at the Cakap level and needs to be given proper learning, namely problem-based learning; (2) some calculation notations are not proper so that it is necessary to strengthen problem-solving procedures so that there are no errors in strategy selection. The results of this study are expected to be used as a reference for further research related to students' mathematical literacy skills with kinesthetic learning styles.

Metacognitive ability is one of the important factors that affect students' mathematics learning achievement. This study investigated the profile of students' metacognitive ability. This study aimed to describe the level of students' metacognitive abilities in general and based on each aspect and indicators. The method of this research is descriptive quantitative by taking 1 class as sample from 4 classes population, with the sampling method used is random sampling. The instruments used in this research was Metacognitive Awareness Inventory (MAI) questionnaire. The results showed tha generally most of students have a good and good enough metacognition ability. It is also found that for each aspect most of students have good and good enough metacognition knowledge and metacognition skills. Meanwhile, based on its indicator for each aspect it is found that there were students with poor declarative knowledge (aspect of metacognition knowledge) and also there were students with poor evaluation skills (aspect of metacognition skills). For others indicators, it is found that students have good and good enough procedural knowledge, condisional knowledge, planning skills, and monitoring skills.Keywords: Metacognitive ability, metacognitive knowledge, metacognitive skills.

This research conducted to evaluate the implementation of the Learning Environment Survey for senior high school teachers in Indonesia which has been carried out in September and October 2021. This is a qualitative-research using in-depth interview techniques. Sources of data are seven teachers of MAN (a government Islamic school) in Alor island, Indonesia, who have filled out this survey in September and one proctor of the National Assessment of MAN Alor. Data analysis is caried out by looking for sub-themes, then determining the relationship between sub-themes to gain understanding. The results of the research are as follows: first, the teacherâ€™s data which are used as the basis for determining the respondents to the survey is considered not valid enough. Secondly, several questions in the survey were considered too sensitive to be questioned because seems like to stir up the privacy of the education unit. The third, questions in this survey are considered too many, too long, and repeat the same sentence a lot
