This study provided an overview of the response of secondary school students regarding the learning from home policies in mathematics learning in four Provinces, Aceh, North Sumatra, Riau, and Jambi. Participants in this quantitative descriptive study were secondary school or equivalent students, amounting to 490 students who were selected based on convenience sampling. Data shows that only 30 percent of students who feel happy to do online mathematics learning, and as many as 62 percent of students experience obstacles on it. They are categorized into four things: Mathematical material that is very difficult to understand, there is no interaction between teacher and student as well as students and students, electricity and internet problems, and not focused on learning. While students who feel happy have a reason for the flexibility of time and place, as well as supporting social distancing recommended by the government. Then it is necessary to evaluate online mathematics learning because students' responses affect learning success.

Abstract. The main purpose of this quasi-experimental study was to determine the enhancement of spatial ability of junior high school students who learned through Cabri-3D assisted collaborative learning. The methodology of this study was the nonequivalent group that was conducted to students of the eighth grade in a junior high school as a population. Samples consisted one class of the experimental group who studied with Cabri-3D assisted collaborative learning and one class as a control group who got regular learning activity. The instrument used in this study was a spatial ability test. Analyzing normalized gain of students' spatial ability based on mathemathical prior knowledge (MPK) and its interactions was tested by two-way ANOVA at a significance level of 5% then continued with using Post Hoc Scheffe test. The research results showed that there was significant difference in enhancement of the spatial ability between students who learnt with Cabri 3D assisted collaborative learning and students who got regular learning, there was significant difference in enhancement of the spatial ability between students who learnt with cabri 3D assisted collaborative learning and students who got regular learning in terms of MPK and there is no significant interaction between learning (Cabri-3D assisted collaborative learning and regular learning) with students' MPK (high, medium, and low) toward the enhancement of students' spatial abilities. From the above findings, it can be seen that cabri-3D assisted collaborative learning could enhance spatial ability of junior high school students .

AbstrakPelaksanaan pembelajaran matematika memiliki tujuan utama yaitu memperkuat kemampuan peserta didik dalam memecahkan masalah. Namun, Kemampuan peserta didik dalam memecahkan masalah masih terbilang minim. Untuk mengetahui seberapa baik siswa dapat memecahkan masalah adalah tujuan dari penelitian ini dan mencari tahu efek serta korelasi antara tingkat resiliensi matematis yang dimiliki peserta didik dengan kemampuan mereka dalam pemecahan masalah matematis. Penelitian ini menggunakan metode penelitian kuantitatif dengan pendekatan berbasis survei. Penelitian ini dilakukan dengan menggunakan sampel dari peserta didik kelas XI IPS SMA Negeri 106 Jakarta sebanyak 67 peserta didik kelas XI IPS SMA Negeri 106 Jakarta yang dipilih menggunakan teknik simple random sampling. Penelitian dimulai dengan menyebarkan angket kepada peserta didik untuk mengukur resiliensi matematis mereka serta menyebarkan soal tes matematika untuk mengetahui ukuran kapasitas seseorang untuk memecahkan permasalahan matematis. Berlandaskan hasil pengujian analisis regresi linier sederhana menggunakan aplikasi IBM SPSS yakni menunjukkan besar nilai koefisien korelasinya R yaitu 0,577 dengan R2 = 33,30%. Dari hasil pengujian tersebut mengindikasikan besar efek resiliensi matematis mencapai 33,30% pada kemampuan pemecahan masalah matematis peserta didik.AbstractThe primary objective of implementing mathematics instruction is to improve students' problem-solving skills. Nonetheless, the problem-solving skills of students remain limited. The purpose of this research is to determine how effectively students can solve issues, as well as the influence and association between their degree of mathematical resilience and their capacity to solve mathematical difficulties. This research utilizes a survey-based quantitative research methodology. This research was conducted using a sample of students from class XI IPS SMA Negeri 106 Jakarta. 67 students from class XI IPS SMA Negeri 106 Jakarta were recruited using a technique of simple random sampling. The project was initiated by providing questionnaires to students to gauge their mathematical resilience and math exam questions to determine a person's capacity to solve mathematical difficulties. Based on the findings of a basic linear regression analysis using the IBM SPSS program, the correlation coefficient R is calculated to be 0.577, with R2=33.30 %. The test findings suggested that mathematical resilience has a 33.30 % impact on pupils' arithmetic problem-solving skills.

Abstract. The aim of this research was to determine the effect of learning models on mathematics achievement viewed from student's self-regulated learning. The learning model compared were discovery learning and problem-based learning. The population was all students at the grade VIII of Junior High School in Boyolali regency. The samples were students of SMPN 4 Boyolali, SMPN 6 Boyolali, and SMPN 4 Mojosongo. The instruments used were mathematics achievement tests and self-regulated learning questionnaire. The data were analyzed using unbalanced two-ways Anova. The conclusion was as follows: (1) discovery learning gives better achievement than problem-based learning. (2) Achievement of students who have high self-regulated learning was better than students who have medium and low self-regulated learning. (3) For discovery learning, achievement of students who have high self-regulated learning was better than students who have medium and low self-regulated learning. For problem-based learning, students who have high and medium self-regulated learning have the same achievement. (4) For students who have high self-regulated learning, discovery learning gives better achievement than problem-based learning. Students who have medium and low self-regulated learning, both learning models give the same achievement. t.
