<![CDATA[This research aims to describe students' critical thinking abilities. Critical thinking skills are very necessary in accordance with educational goals and in improving the quality of human resources (HR). This type of research is descriptive research with the data analysis used is a literature review. A review was carried out on 10 journals that studied students' critical thinking abilities. Based on the analysis carried out, it was concluded that critical thinking skills must be possessed by every student. This ability can occur with collaboration between students and teachers, where a teacher must have expertise in creating dynamic problems so that students can be stimulated to solve the problems given and create very creative ideas. This critical thinking ability can certainly be the basis for creating human resources who are critical and creative and have high competitiveness.]]>

<![CDATA[This research aims to see the extent of students' confidence in themselves in improving and developing their abilities in solving each problem given in the basic statistics course. This type of research is quantitative research using secondary data sources. The population in this study were all third semester students of the Design and Fashion Vocational Education Study Program, totaling 49 people. The sampling technique in this research was to use total sampling so that the number of samples in this research was 49 people. The data analysis technique used is inferential data analysis using a one-way Product Moment correlation test. Based on the analysis of the data that has been used, a value with a strong correlation interpretation is obtained. Based on the calculated t value obtained, which is 7.51 and compared with the t table value, which is 1.678, then 7.51 > 1.678, this means that the hypothesis in this study is accepted or in other words there is a significant relationship between self-efficacy and program student learning outcomes. design and fashion vocational education studies]]>

<![CDATA[This study aims to see the extent to which students' self-confidence in improving mathematical communication skills. The study also examines several other aspects that can improve students' mathematical communication skills. The research method used in this study is the Systematic Literature Review (LSR) using 3 steps, namely the stage of collecting articles on Google Scholar and Sinta. At this stage, 35 research articles were obtained, then the second stage was carried out, namely identification. In this second stage, elimination was carried out on the articles obtained because the articles did not match the focus of the research according to the stated research objectives. The next stage is the stage of critical analysis of the five articles that have been obtained. Based on this analysis, it was concluded that good mathematical communication skills occur if the characteristics of the student's self-confidence are in the high and medium categories, while students with low self-confidence characteristics have an impact on poor mathematical communication. In addition, good mathematical communication can also occur by paying attention to gender equality and providing new learning experiences so that students can explore all the abilities that exist in each of them. This learning experience can be done by using a project-based learning model and is related to everyday life]]>

<![CDATA[This study aims to determine the extent of understanding of the material of plane and spatial shapes through the architecture of the Grand Mosque of Syahrun Nur Sipirok. The research method used in this study is descriptive qualitative. This research data was obtained by using observation and structured interviews. The data analysis technique used is triangulation using four steps, namely 1) Description, 2) Reduction/Focus, 3) Selection, 4) Conclusion. The study began with the identification of the problems found and then determined the focus of the problem, namely finding the concept of learning geometry through an in-depth study of the architecture of the Grand Mosque of Syahrun Nur. Data were obtained from 11 respondents who were visitors to the Mosque who were still high school students, based on the results of interviews conducted with respondents, it can be concluded that learning carried out by the method of direct introduction to learning objects is more effective in increasing students' understanding of the material of plane and spatial shapes than conventional learning which only focuses on theories and examples that are abstract and difficult to interpret. Analysis carried out on tourist objects around us can make learning more enjoyable so that the set learning objectives are achieved optimally.]]>

<![CDATA[ABSTRAK Kemampuan pemecahan masalah merupakan salah satu kemampuan yang sangat penting yang harus dimiliki oleh setiap siswa diberbagai jenjang pendidikan. Penelitian ini bertujuan untuk melihat gambaran kemampuan pemecahan masalah matematis siswa Khususnya di Kelas VII SMP Negeri 10 Padangsidimpuan. Populasi dalam penelitian ini adalah seluruh siswa Kelas VII SMP Negeri 10 Padangsidimpuan yang terdiri dari 4 kelas yang berjumlah 126 orang. Teknik pengambilan sampel dilakukan dengan teknik random sampling sehingga sampel dalam penelitian sebanyak 62 orang. Instrumen penelitian dalam penelitian ini adalah dengan menggunakan essay test dan setelah data dikumpulkan maka data tersebut dianalisis dengan menggunakan dua cara yaitu pertama analisis secara deskriptif, sedangkan analisis data yang kedua adalah analisis statistik inferensial dengan menggunakan rumus uji-t (t-tes). Berdasarkan analisis secara deskriptif diperoleh kesimpulan bahwa penguasaan siswa terhadap materi Penguasaan pecahan berada pada kategori “Cukup”. Hal ini terlihat dari rata-rata penguasaan pecahan yang diperoleh dari pengumpulan data mencapai 65,79. Selanjutnya untuk kemampuan pemecahan masalah matematis siswa berdasarkan analisis yang dilakukan diperoleh kesimpulan bahwa thitung = 14,554 apabila dibandingkan dengan ttabel pada taraf signifikan 95% atau tingkat kesalahan 5% dengan derajat kebebasan (dk) = N – 2 = 62 – 2 = 60, diperoleh ttabel = 1,669. Dengan membandingkan nilai thitung dengan ttabel terlihat bahwa thitung > ttabel yakni 14,554> 1,669. Berdasarkan perhitungan tersebut, maka hipotesis yang dirumuskan dalam penelitian ini diterima atau disetujui. Artinya “Kemampuan pemecahan masalah matematis siswa meningkat dengan adanya pemberian masalah – masalah terbuka pada soal latihan siswa di kelas VII SMP Negeri 10 Padangsidimpuan”.]]>

<![CDATA[Education and these skills can be obtained from the learning process in schools including students' mathematical problem solving abilities. This study aims to look at the description of mathematical problem solving abilities in students with high and low initial abilities, especially in Class X SMA Negeri 1 Padang Bolak. The population in this study were all students of Class X SMA Negeri 1 Padang Bolak which consisted of 5 classes totaling 150 people. The sampling technique was carried out by random sampling technique so that the sample in the study was as many as two classes, namely X2 and X3 classes. The research instrument in this study was to use an essay test in the form of open questions (Open-Ended). Based on the first hypothesis test, it was concluded that the value of Sig. < 0.05 or 0.0005 < 0.05 then H0 is rejected and H1 is accepted. Thus, it can be concluded that the problem solving abilities of students with high initial abilities who are taught using an open-ended approach are better than students with high initial abilities who are taught using a conventional approach. Furthermore, based on the second hypothesis test, it can be seen that the problem-solving ability has a Sig value. of 0.0195. It means the value of Sig. < 0.05 or 0.0195 < 0.05 means that H0 is rejected and H1 is accepted. Thus, it can be said that the problem solving abilities of students with low initial abilities who are taught with an open-ended approach are better than students with low initial abilities who are taught using conventional learning.]]>
