Developing the ability of absolute thinking is needed in mathematic class where the subject has a characteristic as a branch of science which the object of study is abstract-natured and related with a pattern of thinking. Basic mathematics is one of the courses that can develop student’s ability to think. The results acquired by the students are still not maximized; this is because the students struggle to develop their own knowledge to form concepts. Student’s activities in the learning process are only skill-natured in solving problems. One of the learning methods that can be implemented is the Modified Moore method. This research aims to discover the effects of mathematical thinking capabilities with the Modified Moore Method towards the learning achievement of Basic Mathematic II of Chemistry study program from the FKIP of Universitas Riau in the even semester of 2013/2014 academic year. The form of this research is a quasiexperimental research. The experiment design used in this research is the Single Group Pretest/Posttest Design which includes Quasi Experimental Design without control group. The population in this research is the students of Chemistry study program from the FKIP of Universitas Riau in the even semester of 2013/2014 academic year. The sample of this research is all students of Chemistry study program from the FKIP of Universitas Riau in the even semester of 2013/2014 academic year consisting 36 peoples. The sample is obtained through purposive sampling technique. Based on data analysis using t test on mathematical thinking capabilities by applying modified Moore Method, it was found that students scores during post test is better than pre-test. The influences of mathematical thinking capabilities with modified Moore Method of the results learning mathematics basic II Chemistry Education in second semester academic year 2013/2014 is equal to 98,85%. It can be concluded that there is an influence on the mathematical thinking capabilities by applying Modified Moore Method towards the students learning achievement of Basic Mathematic II of Chemistry study program from the FKIP of Universitas Riau in the even semester of 2013/2014 academic year.

The phenomenon of using social media as online media is getting more massive this decade. Young people as a millennial generation are the biggest users in the use of social media today. Research on digital literacy is still rare, especially in Indonesia. Based on this phenomenon, this study aims to map students’ digital mathematical literacy through e-learning in the Covid-19 era. This research uses a quantitative approach with a case study method. Informants were used as research samples of 8 postgraduate students at Riau University. Student digital literacy ability data was collected through online questionnaires using Google Form, then analyzed descriptively using SPSS Program version 23.00 for Windows. The findings obtained in this study indicate the importance of digital literacy capabilities that have a positive impact on knowledge, understanding and skills in using media, especially social media, which is now often used as a source of information by the public, especially by students. Seeing the results of the study, researchers recommended the need for universities or leaders so that students can improve their digital literacy abilities.

Penelitian ini adalah penelitian tindakan kelas yang bertujuan untuk memperbaiki proses pembelajaran dan meningkatkan hasil belajar matematika dengan menerapkan model Problem Based Learning (PBL). Subjek pada penelitian ini adalah siswa kelas VIII-B SMP PGRI Pekanbaru semester genap tahun pelajaran 2019/2020 yang terdiri dari 16 orang siswa laki-laki dan 14 orang siswa perempuan. Instrumen penelitian terdiri dari perangkat pembelajaran dan instrumen pengumpul data. Perangkat pembelajaran yang digunakan adalah Silabus, Rencana Pelaksanaan Pembelajaran (RPP) dan Lembar Aktivitas Siswa (LAS). Instrumen pengumpul data yang digunakan adalah lembar pengamatan dan tes hasil belajar matematika. Data dari lembar pengamatan dan data dari tes hasil belajar matematika dianalisis dengan teknik analisis statistik deskriptif. Hasil penelitian ini menunjukkan bahwa proses pembelajaran mengalami perbaikan dari siklus I ke siklus II, terlihat dari pencapaian  hasil belajar matematika siswa pada aspek pengetahuan dan keterampilan. Data dari tes hasil belajar siswa menunjukkan bahwa  persentase siswa yang mencapai Kriteria Ketuntasan Minimal (KKM) meningkat dari 10 siswa (33,33%) ke 16 siswa (53,33%)  pada siklus I dan 20 siswa (66,67%) pada siklus II. Kesimpulan dari penelitian ini adalah penerapan model Problem Based Learning (PBL) dapat memperbaiki proses pembelajaran dan dapat meningkatkan hasil belajar matematika siswa kelas VIII-B SMP PGRI Pekanbaru  tahun pelajaran 2019/2020 pada materi Teorema Phytagoras.

This study aims to (1) Determine the implementation of curriculum 2013 in Mathematics on SMPN of Pekanbaru, the academic year 2016/2017. (2) Knowing what obstacles faced by Mathematics teachers SMPN of Pekanbaru in the implementation of kurikulm 2013. This study is a qualitative descriptive study, which describes the implementation of the curriculum 2013 by Mathematics teachers of SMPN Pekanbaru and the constraints they face. Subjects in this study are Mathematics teachers in SMPN Pekanbaru that implementing the curriculum 2013, such as SMP 1, SMP 6 and SMP 23 Pekanbaru. The data collection by conducting surveillance documents, and interviews with Mathematics teachers. Based on data analysis, learning process based curriculum 2013 in Pekanbaru SMP has not gone well. There are some problems in the implementation of the curriculum 2013 at SMPN Pekanbaru such as, (1) Teacher have a problem to making Student Activity Sheet; (2) Lack of teacher knowledge about models, strategies, or approach about student-centered learning; and (3) Lack of understanding about the assessment of teachers especially skills assessment.
