Abstract

The implementation of this research is due to indications of learning problems related to students' difficulties in understanding mathematics in division material in third grade elementary school which results in students being weak in understanding mathematical concepts. This needs to be improved through the implementation of a brain-based learning model with an open-ended approach so that it affects students' understanding of mathematical concepts. Quasi-experiment with pretest posttest control group design was used as the basis for this research method. The study population consisted of 96 grade 3 students from 5 schools in cluster 5, Klaten. Simple randomization was used as a sampling technique with a sample of 48 students. The research instrument used was a test of 10 questions with essay type. Based on the results of the hypothesis test obtained at 0.018, the brain-based learning model assisted by an open-ended approach has an effect on students' understanding of mathematical concepts with an average increase of 34.96 seen from the pretest and posttest. This research contributes to influencing students' mathematical concept understanding ability in a more positive direction through collaboration between the brain-based learning model with an open-ended approach.

Abstract

This research is motivated by the low problem-solving ability of students caused by focusing on memorizing formulas when answering questions. Innovation is needed to overcome this, one of which is through the innovative implementation of the creative problem-solving model. This study aims to see the effect of students' problem-solving skills through implementing the creative problem-solving model with the RME approach. This study uses a type of quasi-experiment with a non-equivalent control group design in class 6 on the material of building space. The population was 73 students, with a sample of 40 students consisting of 20 experimental classes and 20 control classes with simple random sampling techniques. The ice instrument used is a description test with as many as four questions. The t-test results obtained are Sig. 0.001 with a t-count of 2.387. Based on the test results that have been carried out, there is a positive influence on the implementation of the creative problem-solving model with the RME approach on students' problem-solving skills, and there is an increase in students' problem-solving skills based on the pretest-posttest value of 31.6.

Abstract

The meaningfulness of math learning in multiplication material is still lacking. This can be seen from students who do not care when they get low results in multiplication learning and are considered boring for students. In overcoming these problems, it is necessary to have the meaningfulness of mathematics learning, one of which is through the Meaningful Instruction Design model with the help of Comics in achieving a better understanding of the concept of multiplication. The type of research used is pre-experiment with pretest-posttest one group de-sign design. The study population was 25 third grade students selected by random sampling technique with a sample of 20 students. From the results of hypothesis testing, the significance of 0.00 < 5% was obtained so that it was stated that the Meaningful Instruction Design model assisted by Comics had an effect on understanding multiplication. Based on the results of the study, students' understanding of multiplication can increase due to the implementation of the Meaningful Instruction Design model assisted by Comic media. However, in order to produce new contributions using the Meaningful Instruction De-sign model can be applied to other mathematics materials. Kebermaknaan pembelajaran matematika pada materi perkalian masih kurang. Hal ini dilihat dari siswa yang tidak peduli ketika mendapatkan hasil yang rendah pada pembelajaran perkalian serta dianggap membosankan bagi siswa. Dalam mengatasi masalah tersebut, perlu adanya kebermaknaan pembelajaran matematika, salah satunya melalui model Meaningful Instruction Design dengan berbantuan Komik dalam mencapai pemahaman konsep perkalian menjadi lebih baik. Jenis penelitian yang digunakan adalah pre-eksperimen dengan desain pretest-posttest one group design. Populasi penelitian sebanyak 25 siswa kelas III yang dipilih dengan teknik random sampling dengan sampel sebanyak 20 siswa. Dari hasil uji hipotesis diperoleh signifikansi 0,00 < 5% sehingga dinyatakan bahwa model Meaningful Instruction Design berbantuan Komik berpengaruh terhadap pemahaman perkalian. Berlandaskan hasil penelitian, pemahaman perkalian siswa dapat meningkat dikarenakan adanya implementasi model Meaningful Instruction Design berbantuan media Komik. Namun, agar dapat menghasilkan kontribusi baru menggunakan model Meaningful Instruction Design dapat diterapkan pada materi matematika lainnya.
