Analysis of Mathematics Problem Solving Ability Based on Contextual Teaching and Learning Models Assisted by Macromedia Flash on Private Junior High School Students Al-Hikmah Medan

The main target of the current study is to explain the metacognition of junior high school students with Field Independent (FI) and Field Dependent (FD) cognitive styles in mathematics problem-solving. It should be noted that the statistical population of this study was all junior high school students in the Sragen regency in the 2018/2019 academic year. To reach the research purpose, different instruments such as the cognitive style tests, the problem-solving exercises, and the interview guidance were used. Data analysis was carried out by data collection, data reduction, data presentation, and conclusion. The results indicated that the students who have field-independent cognitive style had high self-confidence that they were able to solve the problem correctly, able to do planning steps, able to make important decisions for themselves, so they can solve the problem properly. Students with FD cognitive style are completely confident that their answer is correct, but they have not yet clarified the steps they need to solve their problems and have not yet focused on their shortcomings in mathematics problem solving, so their task results in mathematics problem-solving incorrectness answer.

This study aimed to examine comprehensively the effect of the application of REACT learning models based on the Malay cultural context of Riau on students’ mathematical problem-solving abilities. The research was a quasi-experimental research with Pretest-post-test control group design. The sample of this study was all students of class VII SMP 12 Pekanbaru. The results of data analysis were: (1) There was a difference of the mathematical problem-solving ability of Pekanbaru junior high school students between who learned to use REACT learning models based on the Malay cultural context of Riau and students who studied with conventional learning; (2) There was a difference of the mathematical problem-solving ability of Pekanbaru junior high school students between who learned to use REACT learning models based on the Malay cultural context of Riau and students who studied with conventional learning in terms of aspects of student ability levels, (3) There was no interaction between the learning model and the level of students’ ability to the ability to solve mathematical problems; (4) There was a difference in the mathematical problem-solving ability of Pekanbaru junior high school students who learned to use the REACT learning model based on the Malay Malay cultural context in terms of aspects of student ability levels.

Contextual Teaching

Penelitian ini bertujuan untuk menghasilkan media Pop-Up Book berbasis Contextual Teaching and Learning (CTL) dalam pencapaian kemampuan pemecahan masalah siswa SMP yang valid, praktis, dan efektif. Penelitian ini adalah penelitian pengembangan Thiagarajan dengan 3 tahap yaitu tahap define, design, dan develop. Produk valid dilihat dari hasil validasi ahli, produk praktis dilihat dari hasil angket, sedangkan produk efektif dilihat dari hasil uji coba. Hasil validasi para ahli memperoleh aspek materi dinyatakan valid dengan hasil sebesar 82,42%, sedangkan aspek media dinyatakan sangat valid dengan hasil sebesar 86,15%. Hasil angket respon guru memperoleh hasil sebesar 90,59%, sedangkan hasil angket respon siswa diperoleh hasil sebesar 89,12% dengan kriteria sangat praktis. Hasil uji coba memperoleh hasil sebesar 81,58% dengan kriteria efektif dimana terdapat 31 siswa yang tuntas dan 7 siswa yang tidak tuntas dari standar kelulusan minimum yang ditentukan oleh sekolah adalah 75 untuk mata pelajaran matematika. Dengan demikian, dapat disimpulkan media Pop-Up Book berbasis CTL dapat menfasilitasi pencapaian kemampuan pemecahan masalah siswa SMP. AbstractThis study aims to produce a Pop-Up Book media based on Contextual Teaching and Learning (CTL) in achieving valid, practical, and effective problem solving abilities of junior high school students. This research is a Thiagarajan development study with 3 stages: define, design, and develop. The validity of the product is seen from the results of expert validation, the practicality of the product is seen from the results of the questionnaire, while the effectiveness of the product is seen from the results of the trial run. The results of the validation of the experts obtained the material aspect was declared valid with 82.42%, while the media aspect was declared very valid with 86.15%. The results of the teacher questionnaire responses obtained of 90.59%, while the results of student response questionnaires obtained of 89.12% with very practical criteria. The trial results obtained of 81.58% with effective criteria where there are 31 students who completed and 7 students who did not complete the minimum graduation standards determined by the school is 75 for mathematics. Therefore, it can be concluded that CTL-based Pop-Up Book media can facilitate the achievement of junior high school students' problem solving abilities.
