Abstract

Higher education is a level of education that is able to produce and prepare graduates so that college graduates are able to compete and are ready to face the world of work. The aim of this research is to determine the dominant factors that influence the study period and waiting time for undergraduates in Department of Mathmatics FST UIN Sumatera Utara Medan until they get their first job in less than 9 months. The Least Absolute Shrinkage And Selection Operator (LASSO) method was used in this research, where this method is expected to be able to provide high accuracy results in terms of determining the most dominant factors. From the results of calculations using the LASSO method, the three most dominant factors that greatly influence the study period and waiting time for undergraduates are working status (X3), organizational participation (X5), grade point average (X2), final assignment position (X2). By producing this most dominant factor, it is hoped that mathematics study programs will care more about their students by making major and minor improvements to future accreditation

Abstract

Critical thinking skills are one of the skills that students must have. This skill can be trained through various scientific disciplines, one of which is physics. If we look at its characteristics, temperature and heat physics material is able to train students critical thinking skills using the knowledge and experience they have. But in reality, students consider temperature and heat material to be difficult and boring. This is due to lack of student involvement and lack of student understanding of temperature and heat material. Therefore, this research aims to determine the improvement of students' critical thinking skills through the use of the PIMCA learning model assisted by HOTS-based LKPD on temperature and heat material. The research method used is quantitative with a one group pretest-posttest design. The research instrument is a critical thinking skills test in the form of an essay. Data analysis of critical thinking skills test results includes normality testing, hypothesis testing, and continues with the n-gain test to obtain in-depth information regarding students critical thinking skills. In general, the research results show that the average critical thinking skills of students is 0.76 in the high category. High levels of critical thinking skills can be seen in the categories of elementary clarification, basic support, inference, and strategy and tactics. Meanwhile, students critical thinking skills in the category of advanced clarification are still in the medium category.

Abstract

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.

Abstract

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.

Abstract

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.
