<![CDATA[Â ABSTRACTThe purposes of this study are to know the different effect of each category of learning model, curiosity, and cognitive style, also their interaction towards mathematics achievement. This study is a quasi experimental research with 2x3x2 factorial design. The population is all students of junior high school in Blora. Sampling was done by stratified cluster random technique. The instruments used to collect data are test of prior knowledge in mathematics, curiosity questionnaire, cognitive style test (GEFT), and mathematics achievement test. The testing of hypothesis uses three-way analysis of variance with unequal cell. The testing of hypothesis concludes that (1) There is a different effect between each category of learning model. (2) There is a different effect among each category of curiosity. (3) There is a different effect among each category of cognitive style. (4) There is an interaction between learning model and curiosity towards mathematics achievement. (5) There is an interaction between learning model and cognitive style towards mathematics achievement. (6) There is an interaction between curiosity and cognitive style towards mathematics achievement. (7) There is an interaction among learning model, curiosity, and cognitive style towards mathematics achievement.Keywords: NHT, STAD, Curiosity, Cognitive Style, Mathematics Achievement]]>

<![CDATA[Penelitian ini bertujuan untuk mengkaji efektivitas metode pembelajaran Preview, Question, Read, Reflect, Recite, Review (PQ4R) ditinjau dari pemahaman konsep matematis siswa. Populasi penelitian ini adalah seluruh siswa kelas VII SMP Negeri 20 Bandarlampung semester genap tahun pelajaran 2018/2019 sebanyak 346 siswa yang terdistribusi ke dalam sebelas kelas. Dari sebelas kelas tersebut diambil satu kelas secara acak sebagai sampel penelitian.Penelitianinimenggunakanone-group pretest-posttest design. Data penelitian diperoleh melalui tes berbentuk uraian pada materi Segiempat dan Segitiga. Analisis data penelitian ini menggunakan uji t berpasangan. Hasil penelitian menunjukkan pemahaman konsep matematis siswa setelah mengikuti pembelajaran dengan metode PQ4R lebih tinggi dibandingkan pemahaman konsep matematis siswa sebelum mengikuti pembelajaran dengan metode PQ4R namun persentase siswa yang memiliki pemahaman konsep terkategori baik tidak lebih dari 60% dari banyaknya siswa yang mengikuti pembelajaran metode PQ4R. Dengan demikian, metode PQ4R tidak efektif ditinjau dari pemahaman konsep matematis siswa.Abstract This study aimed to find out the effectiveness of the Preview, Question, Read, Reflect, Recite, Review (PQ4R) learning method in terms of students' understanding of mathematical concepts. The population of this study was all seventh grade students of SMP Negeri 20 Bandarlampung in the even semester of the academic year of 2018/2019 as many as 346 students that distributed into eleven classes. The sample was taken randomly one class of the eleven classes as the study sample. This study used the one-group pretest-posttest design. The research data was obtained through a essay test of the quadrilateral and triangle. Data analysis of this research used paired t-test. The results showed that students' undestanding of mathematical concepts after taking the PQ4R learning method was higher than students' understanding of mathematical concepts before taking the PQ4R learning method, but the percentage of students who had a good understanding of the mathematical concepts was not more than 60% of the number of students who took PQ4R learning. Thus, PQ4R method was not effective in terms of students' understanding of mathematical concepts. ]]>

<![CDATA[This study aimed to describe students' interest in mathematics and its relation with learning methode and self- efficacy. The population of this research were junior high school students in Bandarlampung. This is a quantitative descriptive research, studied 691 students which were selected using the stratified random sampling technique. Data in this study consisted of data on student’s interest in mathematics (Y), learning methode (X1), and student’s self-efficacy (X2) which were obtained using questionnaires. Data analized using correlation and multiple linear regression with α = 0.05. It were concluded that: (i) 22.58% of students have interests in high category, 76.56% with moderate category, and 0.86% in low category; (ii) there is a very strong positive relationship between the variables of learning method and self-efficacy together towards the variables of interest with a value of r = 0.844; (iii) there is a strong positive relationship between learning method and interest in mathematics when no change of self-efficacy with r = 0.505; (iv) there is a strong relationship between self- efficacy and interest in mathematics when the learning method does not change with r = 0.585; and (v) the formula of the linear regression model is Y = 22,788+0,972 X1+0,932 X2.DOI: 10.22342/jpm.13.1.6750.83-100]]>

<![CDATA[Problem solving is a process that requires logical thinking to find solutions to the problems faced. Through this process, students will learn to develop appropriate strategies to solve the problems. This study aims to identify errors made by students in solving problems on the material of function derivatives. The method used in this study is descriptive qualitative, with data collection techniques carried out through previous literature reviews. The results of the study showed that students made mistakes at several stages, namely in understanding the problem, designing a solution strategy, implementing the solution, and at the re-checking stage. Based on the type of error, students made mistakes in terms of facts, concepts, principles, and operations. The proposed solution is to accustom students to be more careful in solving problems based on problem-solving steps, especially at the final checking stage, and to improve their mastery of algebraic operations and basic factoring techniques.
