This study aimed to improve the students’ productive disposition (PD) through Realistic Mathematics Education (RME) learning with an outdoor approach based on school level. Productive disposition development is intended so that students can appreciate mathematics as a science needed for their lives. The method used in this research was a quasi-experimental study. The population was 210 students of the fifth grade of Elementary School from five schools. The sample was 75 fifth grade students. The data were collected by using a questionnaire. Data were analyzed using t-test to find out the difference between the experimental and the control group. The results of this study indicate that RME learning with the outdoor approach more influential than the conventional learning in improving PD in high school level. Otherwise, in medium and low level school, the conventional learning was more influential than the RME learning with the outdoor approach to improve the students’ PD. Therefore, it can be concluded that the school level needs to be considered in improving students’ productive disposition through RME learning with an outdoor approach. Moreover, RME learning with an outdoor approach as an alternative model to improve productive disposition of students.

Kemampuan penalaran matematis di masa pandemi Covid-19 masih rendah. Penelitian ini bertujuan mengetahui pengaruh mathematical disposition dan self-concept terhadap kemampuan penalaran matematis mahasiswa. Penelitian ini menggunakan pendekatan kuantitatif ex-post facto. Sampel penelitian berjumlah 83 mahasiswa S1 Pendidikan Matematika di Kota Bengkulu. Instrumen penelitian ini terdiri dari angket mathematical disposition, angket self-concept dan tes kemampuan penalaran matematis. Data dianalisis dengan teknik  analisis regresi. Hasil penelitian menunjukkan bahwa terdapat pengaruh langsung dari mathematical disposition terhadap kemampuan penalaran matematis. self-concept terhadap kemampuan penalaran matematis, dan mathematical disposition terhadap self-concept. Selain itu, terdapat juga pengaruh mathematical disposition dan self-concept secara bersama-sama terhadap kemampuan penalaran matematis. Disimpulkan bahwa terdapat pengaruh mathematical disposition dan self-concept terhadap kemampuan penalaran matematis mahasiswa S1 Pendidikan Matematika di Kota Bengkulu pada masa pandemi Covid-19.Mathematical reasoning ability during the Covid-19 pandemic is still low. This study aims to determine the effect of mathematical disposition and self-concept on students' mathematical reasoning abilities. This study uses an ex-post facto quantitative approach. The Sample of this research was 83 students of S1 Mathematics Education in Bengkulu City. The research instrument consisted of a mathematical disposition questionnaire, a self-concept questionnaire, and a mathematical reasoning ability test. Data were analyzed by regression analysis technique. The results showed there was a direct influence of mathematical disposition on mathematical reasoning abilities, self-concept to mathematical reasoning ability, and mathematical disposition to self-concept. In addition, there is also the effect of mathematical disposition and self-concept together on mathematical reasoning abilities. It was concluded that there was an influence of mathematical disposition and self-concept on the mathematical reasoning ability of S1 Mathematics Education students in Bengkulu City during the COVID-19 pandemic.

This study aims to determine the basic concepts and values of mathematics contained in traditional Bengkulu musical instruments in elementary schools. The urgency of this research is to use regional culture in learning mathematics theoretically and practically as a medium and source of learning mathematics through learning outside the classroom to achieve the objectives of learning mathematics in elementary schools. This research method is a qualitative method with an ethnographic approach. Data sources are in the form of traditional Bengkulu musical instruments, namely dhol, tassa, long drums, and serunai. Other data sources are documents and interviews with experts and practitioners of Bengkulu traditional musical instruments. The data were analyzed qualitatively with the method of content analysis. The result of this study shows that the basic mathematical concepts in Bengkulu traditional musical instruments are points, lines, angles, triangles, quadrilaterals, kites, circles, tubes, half balls, cut balls, cut cones, universes, and patterns. At the same time, the mathematical values contained in traditional Bengkulu musical instruments are obeying the rules, consistency, creativity, and cooperation. Therefore, as an alternative to effective learning in elementary schools, Bengkulu traditional musical instruments can be used as a medium and source of learning mathematics outside the classroom.

[Implementation of outdoor learning with saintific approach to improve student learning of SMPN 6 Bengkulu City]. The aims of this study was to know the results of scientific learning (outdoor) and see the comparison the value of students’s group who learn by using outdoor learning and groups of students who do not use outdoor learning. The subject of this research is the students of class VII SMPN6 Bengkulu City on academic year 2016/2017. The sample who taken are class VII G class control class VII H, experimental class, class VII E as a testing class. Sampling technique by purposive sampling. Instrument used double choice test instrument 25 problem,. The technique of data analysis using statistic Anova Mix (mixed Anova). Test normality by using test of covariance matrix. The average value of pretest of the experimental class students 62.1 after the average treatment of student postes increased to 86.25 which means an increase of 24.15. The control class Pretest and postes results Average score of pretest students 65,9 after conventional learning average student postes score increased to 75,5 which means an increase of 9.6. Student learning outcomes using outdoor learning method is higher than those not using the method, it is seen from the average experimental class value (80,75) bigger than control class (64,00) with increase of 26,37%.    Keywords: Outdoor learning; saintific approach; student learning outcomes.

This research aims to determine the relationship and influence of anxiety and perception on learning mathematics on the concept of understanding. The research used is ex post facto and analyzed using pathway analysis. These instruments use anxiety questionnaires, perception questionnaires about learning mathematics, and understanding concepts. The population in this study is class VIII State Junior High School 16 Bengkulu City in the 2020/2021 school year, with a research sample of 64 people, namely the class. VIII.D numbered 32 people and class VIII.E numbered 32 people. The results showed that anxiety affects the understanding of concepts, the perception of learning mathematics also affects the understanding of concepts. Analysis of hypotheses shows that there is a significant and significant relationship between instruments.
