Publisher : UNIVERSITAS MUHAMMADIYAH METRO

Kemampuan pemecahan masalah matematika (KPMM) adalah suatu kemampuan yang dibutuhkan orang dalam menghadapi tantangan kehidupan. Hal ini dikarenakan melalui pemecahan masalah, siswa dapat menyelesaikan masalah secara bebas dan kreatif. Kenyataanya, KPMM siswa belum berkembang dengan baik. Pembelajaran kontekstual (PK) diperkirakan dapat mengembangkan KPMM siswa. Tujuan penelitian untuk meningkatkan KPMM siswa yang dibelajarkan dengan PK dan pembelajaran konvensional (PKV) dikaji secara keseluruhan dan level sekolah (LS) serta mengkaji ada tidaknya interaksi antara pembelajaran dan LS terhadap peningkatan KPMM siswa. Jenis penelitian adalah eksperimen semu dengan disain kelompok kontrol pretes dan postes. Subjek penelitian siswa SMPN kelas VII LS atas dan tengah di Pekanbaru dengan satu set tes KPMM sebagai instrumen. Analisis data dengan uji Mann-Whitney, Kruskal-Wallis, dan Anava dua jalur. Hasil penelitian: (1) peningkatan KPMM siswa yang dibelajarkan dengan PK lebih tinggi dari PKV, secara keseluruhan: 0.83 > 0.65, LS: 0.95 > 0.72; 0.70 > 0.59; dan (2) ada interaksi yang signifikan antara pembelajaran dan LS terhadap peningkatan KPMM siswa. Kesimpulan: (1) ada peningkatan KPMM siswa setelah memperoleh pembelajaran; siswa yang dibelajarkan dengan PK memiliki peningkatan KPMM lebih tinggi dari siswa yang dibelajarkan dengan PKV, dikaji secara keseluruhan dan LS; dan (2) ada interaksi yang signifikan antara pembelajaran dan LS terhadap peningkatan KPMM siswa.Mathematical problem solving ability (MPSA) is an ability that people need in facing life’s challenges. This is because through problem solving, students can solve problems freely and creatively. In fact students’ MPSA have not developed well. Contextual learning (CL) is expected to be able to develop students’ MPSA. The aim of the study was to improve students’ MPSA who were taught through CL and conventional learning (CVL) as a whole and at the school level (SL) and examine whether there is an interaction between learning and SL towards increasing students’ MPSA. This type of research is quasi-experimental with a pretest and posttest control group design. The research subjects were students of SMPN class VII at upper and middle SL in Pekanbaru with a set of MPSA tests as an instrument. Data analyzed using Mann-Whitney, Kruskal-Wallis and two way Anava tests. The research results show that (1) MPSA improvement of students taught with CL is higher than CVL, overall: 0.83 > 0.65, SL: 0.95 > 0.72; 0.70 > 0.59; and (2) there is a significant interaction between learning and SL towards increasing students’ MPSA. Conclution: (1) there is an increase students’ MPSA after learning; students taught with CL had higher MPSA improvement than students taught with CVL, assessed overall and SL; and (2) there is a significant interaction between learning and SL towards increasing students’ MPSA.

This research is motivated by the limitations of mathematics learning tools to support learning in the 2013 Curriculum. This research aims to produce products in the form of learning tools (syllabus, RPP and LKPD) on SPLTV material for class X SMA with PBL models that meet valid and practical criteria to facilitate students' abilities. The learning device was developed using a 4D model. The development that the researchers carried out consisted of 4 stages, namely: (1) define; (2) design; (3) development; (4) dissemination. The research instrument consists of a validity instrument and a practical instrument. The validity instrument is in the form of a validation sheet to assess the feasibility of the syllabus, lesson plans and worksheets and a practical instrument in the form of a student response questionnaire to determine the readability of the LKPD. Expert validation results show that the product in the form of learning tools reaches the very valid category with average results for the syllabus 92%, lesson plans 93% and LKPD 90%. The learning tools being tested were LKPD categorized as very practical in small group trials with an average student response of 85% in the very practical category.

The Effect of the Application of the 5E Learning Cycle Model on Mathematical Communication Skills in Junior High School Students Putri Aulia Susanti; Nahor Murani Hutapea; Sehatta Saragih
Journal of Educational Sciences Vol 5, No 2: April 2021
Publisher : Universitas Riau

This research is motivated by the low students mathematical communication skills. To overcome this problem is by improving the learning process that provides opportunities for students. One of them is by applying the 5E Learning Cycle model. The 5E Learning Cycle model is a series of activities so that students can master the competencies achieved in learning by taking an active role, directed to seek and discover new knowledge themselves. The research is to investigate the impact of the application of Learning Cycle 5E on mathematical communication skills in terms of overall, ability level and, interaction between learning model and ability level. This research is a quasi-experimental study with a pretest post-test control design. The results of data analysis show that the mathematical communication skills of students who learn using the 5E learning cycle model are better than students with conventional learning. For students mathematical communication skills at the moderate level, the 5E learning cycle model is better, but not better for high and low levels. There is no interaction between the learning model and ability level of mathematical communication skills.
