The subjects of this study were three students who had the most misconceptions from all students in the class. Students' misconceptions in this study were analyzed using a written misconception test with the CRI (Certainty of Response Index) method and continued with interviews to find out the cause of the misconceptions that occurred. Based on the results of data analysis the three subjects showed almost the same misconception. The first misconception experienced by students on rectangular flat figure material lies in the definition of rectangular flat figure. Students' misconceptions in defining lie in a flat shape that has the same side of length, four corners, and two diagonals that form a right angle. This shows that students only choose rectangular regular shapes. In addition, students also experience misconceptions in distinguishing between sides and ribs. The second misconception, lies in the concept of the properties of a rectangular flat shape especially rectangular. Students assume that the rectangle always has an elongated shape without regard to its properties. Furthermore, there is a misconception when showing another wake. Students assume that the ladder is an oblique rectangle. In addition, if a rectangle has a different position or irregular shape then it is not called a rectangle. The cause of the misconception that occurs is the ability to understand the concepts and images given to the problem</span>2020-04-01T12:10:29+08:00Copyright (c) 2020 Mega Teguh Budiarto, Siti Khabibah, Andi Mulawakkan Firdaushttps://ojs.unm.ac.id/JDM/article/view/13317The Effect of Self-Efficacy, Self-Concept, Learning Activities and Independent Learning on Mathematics Learning Achievements2020-04-30T17:11:23+08:00Ernawati Ernawatiernawati@unismuh.ac.id<span>This study aimed to find out (1) the description of self-efficacy, self-concept, learning activities, independent learning, and mathematics learning achievements, (2) the effect of self-efficacy on students’ mathematics learning achievements directly and indirectly through independent learning, (3) the effect of self-concept on students’ mathematics learning achievements directly and indirectly through independent learning, (4) the effect of learning activities on students’ mathematics learning achievements directly and indirectly through independent learning.

The populations of this research were all students of grade class X SMP Negeri 29 Bulukumba and choose one class as the sample of the research by using simple random sampling as the experiment class, clas VII A, was given the treatment of Experiences, Language, Picture, Symbol, and Apllication (ELPSA) Cooperative Setting on STAD type. The data collections consisted of the data of learning model implementation, data of students’ activities, in learning process, data of students’ response on learning instruments, and data of students’ learning result which consisted of the pretest and posttest scores. The data of learning model implementation, students’ activities, and students’ response data were analyzed by using statistic descriptive analysis; whereas, mathematics learning result os students was analyzed by employing statistics descriptive and statistics inferential analysis. The results of the research revealed that (1) the average score of learning implementation level (TKP) was in good criteria (3.50 ≤ x ≤ 4.50) which was 3.17; (2) the average score of students’ activity had met sufficiently active criteria (2.5 – 3.4) which was 2.87; (3) students’ responds is in positive category (3.50 – 4.0) which was 3.51; (4) the everage of students’ learning result before the treatment was in very low category (0 – 54) which was 31.37 from the ideal score 100. The everage of students’ learning result after the treatment was in high category (80-89) which was 81.68 from the ideal score of 100. The everage of students’ improvement score (gain value) was in high category (x ≥ 0.7) which was 0,73. Based on inferential statistic analysis on students’ learning result after the treatment, it was obtained P-value < α (0.01 < 0.05) so H<sub>0</sub> was rejected and H<sub>1 </sub>was accepted where the everage of students’ learning result was higher than 74.9 (KKM), and the everage of students’ learning improvement score (gain value) obtained P-value < α (0.01 < 0.05), so H<sub>0 </sub>was rejected and H<sub>1</sub> was accepted where the everage of students improvement score (gain value) was higher than 0.29.
