Proof of geometry is a topic that involves mathematical reasoning abilities and relates to perseverance involving hard work, the spirit of achievement, and self-confidence. The current important problem that occurs at this time is that students who are future teachers of mathematics still experience difficulties in compiling proofs, especially those who are not challenged to work hard. This qualitative research explores mathematics teacher candidates' reasoning abilities and perseverance in proving geometric theorems. Therefore, the research design used a case study. There were three participants in this study, and they were student prospective mathematics teachers' s taking geometry courses. Data were collected through working documents, open questionnaires, and semi-structured interviews and were analyzed using iterative techniques consisting of data condensation, data exposure, and verification. The study's results showed that students' prospective teachers did not prioritize proof in solving geometry problems, even though they worked hard to solve the problems independently until they were finished. The students' perseverance also impacts their mathematical reasoning in proving geometric theorems. Students with more hard work values tend to have more reasoning values. The results of this study have implications that there needs to be an effort from the teacher to get used to giving proof questions to support students' perseverance and mathematical reasoning abilities.

The purpose of this research is to describe the development of a STEM-based learning environment for early childhood teacher candidates that is valid, practical, and has potential effects. The research sample consisted of 25 pre-service early childhood teachers and 19 students Kindergarten. The research method used was design research with the type of development study. This research has produced a learning environment with the Campus-Application-School (CAS) model consisting of the stages of training, designing, mentoring, and testing. The validity of the STEM-based learning environment model was seen from the developed student worksheet (LKPD) instrument and the content in the learning environment, obtaining a value of 0.88, which was categorized as high validity. The practicality, as seen from the results of one-to-one teaching, small group, and field tests with an average of 94.2, was categorized as very good. Meanwhile, the potential effect was based on Kirkpatrick's four levels of training evaluation with an average of 83.73, which was categorized as very good. This research suggests that the CAS learning environment model can affect teacher approaches to teaching in a step appropriate way based on STEM to prepare student teachers to teach basic mathematics.

Abstract This research is a qualitative descriptive study that aims to find out how the character values of students in learning use HOTS questions with PBL models. Data collection methods used were observation, written tests, and interviews. The focus of this research is the value of the character of curiosity, hard work, thorough, and creative. The results showed that the dominant character values that emerged were curiosity and hard work, which was due to the lack of HOTS type questions making students often ask the teacher how to solve these problems. Then because of the dominant curiosity, students work on the problem with hard work. While the character values the dominant does not appear are thorough and creative characters, it happens because of the lack of student training in working on various math problems making students only focus on what has been taught in the classroom without developing their thinking.

Abstract Learning Mathematical modelling is an important part of mathematics. However, it is difficult to apply in learning. This research is a descriptive study with the aim of studying the learning process of mathematical modelling using worksheets (LKS) based on control and rationalism values in Junior High School Number 13 Palembang. The research subjects consisted of 37 students of class VIII.2. Data collection techniques in this study consisted of observation. Observations were made to see student activities which are appearance of control and rationalism value during the learning process and student activities using worksheets. The results of the study were obtained from student activities based on indicators of control and rationalism value during learning process with an average of 78.375 which were categorized as good result. Besides that, we observe control and rationalism value on worksheet with average of 77.79 which were categorized as good result. All learning processes use modelling stages only at the second meeting the stages of understanding the problem do not arise because the problem used continues from the problem at the first meeting so that it does not result in the emergence of control value indicators in understanding the problem.

Abstract Agriculture is a culture that has been embedded in Indonesian society. Along with the changing times, then this culture began to be abandoned and tend not to be known by the current generation. Ethnomathematics exists to bridge the gap between culture and education. The purpose of this study was to find out the mathematical ideas on oil palm cultivation and determine students’ responses in Ethnomathematics-based learning. This research uses descriptive qualitative. In this study, an assessment of the knowledge, ideas, or findings contained in the literature was carried out to provide theoretical information and interviews to oil palm companies and smallholders related to oil palm cultivation and implemented in mathematics learning. The application of agricultural activities in mathematics learning is expected to introduce and preserve agricultural culture to students and learning becomes more fun and meaningful.

Abstract This study aims to identify teachers’ conceptual understanding in science content using hyperthermia context. The hyperthermia context is used as a pilot project to develop STEM in Mathematics and Science Education Department. This study is a descriptive study involving 42 freshman science pre-service from Biology, Physics and Chemistry Education. The instrument used is 8 essay questions on the context of hyperthermia but requires mastery of radiation, conduction, convection and evaporation on physics content, endothermic and exothermic content on the chemical content and the principle of homeostasis in biological content. From the results of this study obtained data that the pre-service science teacher students (Biology, physics and chemistry) have difficulty to connect issues of nuanced hyperthermia context to the content of physics, biology and chemistry because the prerequisite content that has been learned by the students has never been integrated in the context of hyperthermia, but even thought they have difficulty on it, the hyperthermia have a potential to grow intuitive skill.

Abstract The teacher is a parent for young children in school. In maximizing learning in schools, the role of a teacher is needed. This study aims to describe the learning process for childhood by teachers both in plannng, implementatuon, and evaluaton of geometry and numbers. The subjects of this study were 30 teachers from 20 schools in South Sumatra. The method used is descriptive with qualitative and quantitative types. Data were collected using questionnaires and interviews. The results obtained that the implementation of learning undertaken by teachers both in planning, implementation, and evaluation has been carried out in each school. It’s just that the implementation is not optimal. It is because there is no awareness of the teacher about the need for learning tools, learning is still not following the stages of development due to the limitations of the media and the lack of teacher creativity. It requires training as an evaluation of the activities that have been carried out.

Mathematical learning not only produces students who succeed in mathematical and procedural calculations but also develops religious thinking. Realistic mathematics education with the context of Islamic values makes students can imagine, which is one of the right ways to develop the skills of students’ creativity, collaboration, and communication. This study aims to describe the learning trajectory that can help students understand integers with a realistic mathematics education approach based on Islamic values. It is hoped that student responses are positive, meaningful, and enjoyable. This research uses the design research method, which is a form of a qualitative approach. There are three stages in this research, namely: preliminary design, experimental design, and retrospective analysis. The results showed that the Hypothetical Learning Trajectory (HLT) trial with an Islamic value-based context showed significant progress based on student responses. Initially, students had difficulty understanding integers, but they felt delighted to follow the learning process along with the habituation. The HLT technique used in habituation was through pilot experiments, followed by teaching experiments. Students respond very positively and are happy to follow it by seeing the very significant development of their abilities during the learning process.

Abstract A pod rot disease caused by Phytophthora is one of serious treat on cacao farming system. This infection was reduced annual bean production remarkably (up to 30%). So far, there are seven species of this fungi were identified from the cacao farm over the world. However, we still lack of information on phytophthora properties from Sulawesi farm, which supplied more than 60% Indonesian cacao bean production annually. Here we report our result on isolation, identification, and characterization of these fungi from Sigi-Biromaru area (one of main farming area in Central Sulawesi). We showed that P. nicotianae could isolate from local infected pot. Bioassay on it infection rate was shown depend on the recictency of cacao clones/cultivars. This data suggesting that various species of Phytophthora exist in Sulawesi cacao farm, and its pathogenity was depend on the susceptibility of its clone of cacao.

A math teacher must be able to do lessons with some material, approaches, models, and strategies that are by the plan. This research is a type of descriptive qualitative research, namely trying to analyze the implementation of integer learning with a realistic approach based on Islamic values to strengthen the character of students. The results of this study indicate that the application of learning has not been implemented properly following the Lesson Plan, a step-by-step approach that is not yet maximal, the explanation of Islamic values still needs further understanding by the teacher. But students are happy with the implementation of this learning, indicated by the results of interviews and student activities that are adequate even though it still needs improvement.
