<![CDATA[Inclusive teaching is not something new in the world of Education. However, its emphasis in the Merdeka curriculum makes inclusive teaching steal the attention of many education observers. This study aims to determine the perception of teachers in Indonesia (elementary school teachers, junior high school teachers and senior high school teachers) on the importance of inclusive teaching in learning. This research is a survey study conducted on teachers in Indonesia, with random sampling. The sample number of teachers who were respondents was 46 teachers. To obtain data, researchers used an instrument in the form of a questionnaire in the form of a Likert scale with five scales and yes or no questions. As additional data, researchers conducted interviews conducted on several samples of teachers. The data obtained is then analyzed quantitatively and poured into tables and graphs. From the results of the analysis, it is known that teachers attach great importance to inclusive teaching. 82.61% teachers argue that inclusive teaching is a good idea. However, in reality, the application of inclusive teaching has not been optimal. One of the obstacles in optimizing the application of inclusive teaching is the selection of appropriate learning strategies in inclusion classes. This is what needs to be explored in order to find appropriate learning strategies for inclusion classes.]]>

<![CDATA[Misconceptions in solving story problems involving the System of Linear Equations of Two Variables (SPLDV) are often a challenge for students. This research aims to identify the types of misconceptions experienced by students of grade VIII of Kasih Yobel Junior High School in Singkawang in solving SPLDV story problems, which are studied from the perspective of numeracy literacy. This research used descriptive qualitative method involving six students as research subjects. Data were collected through diagnostic tests and interviews to identify misconceptions based on numeracy literacy components: understanding, use, interpretation, and communication. The results showed that students experienced several types of misconceptions, especially in the translation of story problems into mathematical form, the use of strategies/methods, and calculations. The misconceptions were caused by students' lack of understanding of the basic concepts of SPLDV and inability to apply mathematical symbols and operations correctly. The discussion of the research results emphasizes the importance of learning approaches that strengthen students' numeracy literacy, especially in terms of understanding concepts and applying effective strategies. The conclusion of this study shows that improving numeracy literacy needs to be a priority in mathematics teaching to reduce misconceptions and improve students' ability to solve SPLDV story problems.]]>

<![CDATA[This study aims to describe the creative thinking ability of seventh grade junior high school students in applying the concept of division and identify the factors that cause creative thinking difficulties in that context. This research is based on the importance of understanding mathematical concepts, where creative thinking becomes the foundation in helping students overcome difficulties in understanding the concept of division. The method used was qualitative with an explorative approach. Participants were selected using a purposive sampling technique, focusing on learners who were considered to be able to provide in-depth insights into their creative thinking abilities and the difficulties they faced. The results showed that learners were generally able to generate ideas quickly (fluency) and connect concepts with solutions in a relevant manner, although there were some ideas that were less relevant. Most learners also show flexibility by using various methods in solving problems, but there are some who tend to use only one method. In terms of originality, unique and structured ideas were found, although some were less structured or unable to develop ideas completely. In terms of elaboration, some learners were able to detail ideas well, while others showed weaknesses in detailing and developing ideas. Factors that cause creative thinking difficulties include lack of understanding of basic concepts, limitations in connecting prior knowledge, lack of practice and time, low level of confidence, lack of practice in working on open-ended problems, learning methods that do not support creativity, and lack of motivation.]]>

<![CDATA[This study investigates the preparation of students for the National Olympiad of Mathematics and Natural Sciences for Higher Education (ONMIPA PT), focusing on the selection process at Institut Teknologi Del (IT Del). The research applies the Tahani fuzzy logic method to select students who demonstrate potential across various mathematical disciplines such as Linear Algebra, Abstract Algebra, Real Analysis, Complex Analysis, and Combinatorics. By using fuzzy logic, students' performances are categorized into three levels: less, adequate, and good. The goal is to ensure a well-rounded selection of participants who can excel in all tested areas, rather than choosing those with the highest scores in individual topics. The results demonstrate that fuzzy logic improves decision-making in selecting participants for the competition. Additionally, the study highlights the broader implications of ONMIPA PT in enhancing educational quality and fostering scientific excellence. This research contributes to the development of selection methods for academic competitions, offering insights into the application of fuzzy logic in multi-stage decision-making processes.]]>
