Abstract

This research aimed to determine: 1) coefficient Correlation betweenthe utilization of learning facilities with mathematics learning outcome. 2)coefficient correlation between independence learning with mathematics learning outcome. 3) coefficient correlation utilization of learning facilitiesand learning independence with mathematics learning outcome.The research was conducted in the even semester of 2019. The samplein this research was selected from the whole population of students ofGrade VIII in An Nur Islamic Junior School Palangka Raya in 2018/2019Academic Year, in total 78 students. Type of this research is correlational.Two instruments used in this research were questionnaires and tests.Questionnaires of utilization of learning facilities consists of 24 validstatements with 0,78 reliability coefficient, questionnaires of independencelearning consists of 24 valid statements with 0,90 reliability coefficient, andthe mathematics learning outcome test consists of 25 valid items with areliability coefficient of 0.85.The research results concluded: 1) there is positive correlation thatsignificant between utilization of learning facilities with mathematicslearning outcome (rhit=0,58), 2) there is positive correlation that significantbetween independence learning with mathematics learning outcome(rhit=0,54), 3) there is positive correlation that significant betweenutilization of learning facilities and independence learning withmathematics learning outcome (Rhit=0,73), each at a significance level of5%.

Abstract

This research was motivated by the low scores obtained by students in the trigonometry material for the area of ​​triangles in class X GP of SMK Negeri 4 Palangka Raya. In the 2019/2020 school year, only 48% of the 34 students achieved the school's Minimum Completeness Criteria, which is 65. The purpose of this study is to describe the difficulties experienced by students in solving math problems on trigonometry material and the factors that students experience difficulties. This research is a qualitative descriptive study. The results showed that the difficulties experienced by students in solving trigonometry problems were: (a) Difficulties in counting were difficulties in performing number operations. The factor that causes students to be less careful. (b) Difficulty in transferring knowledge, namely determining the formula and sine value. The reason is that students do not understand the material being taught so they cannot distinguish the formula used in determining the area of ​​a triangle according to what is known in the problem. (c) Difficulty in understanding mathematical language, namely understanding mathematical symbols correctly. The reason is that students are less careful in writing down the numbers that match the existing mathematical symbols. (d) Difficulty in visual perception, namely making and understanding sketches or drawings based on existing problems. The reason is that students do not understand how to change what is asked in the question of the shape of a triangular image and vice versa.
