Abstract

Penelitian pengembangan ini bertujuan untuk menghasilkan produk Lembar Kerja Peserta Didik (LKPD) dengan model pembelajaran Explicit Instruction yang dapat meningkatkan hasil belajar matematis peserta didik yang valid. Penelitian ini menggunakan pengembangan Research and Development (R&D)model 4-D yang meliputi empat tahapan yaitu pendefenisian (define), perancangan (design), pengembangan (develop), dan penyebaran (disseminate). Namun dimodifikasi maka penelitian ini sampai 3-D yang meliputi tiga tahapan yaitu tahapan pendefenisian (define), perancangan (design), dan pengembangan (Develop). Tahapan define merupakan tahapan awal dari permasalahan. Tahapan design dilakukan perancangan perangkat pembelajaran berupa Lembar Kerja Peserta Didik dan Rancangan Pelaksanaan Pembelajaran serta instrumen pengumpulan data berupa lembar validasi. Tahapan develop dilakukan validasi instrumen berupa angket kepada validator oleh ahli media dan guru. Hasil dari penelitian menghasilkan pengembangan Lembar Kerja Peserta Didik (LKPD) dengan model pembelajaran Explicit Instruction untuk meningkatkan hasil belajar matematis siswa kelas VIII yang valid. Berdasarkan hasil dari angket validator lembar kerja peserta didik dapat di nilaidari validasi ahli media dengan rata-rata nilai 3,00 dengan kriteria “Baik” dan apabila dipersentasekan yaitu 75% dalam kategori “Layak” untuk penilaian RPP. Adapun untuk hasil penilaian pada Bahan Ajar yang berupa Lembar Kerja Peserta Didik yaitu 3,02 dengan kriteria “Baik” dan apabila dipersentasekan yaitu 75,55% dalam kategori “Layak”. Kemudia hasil penilaian dari angket peserta didik diperoleh rata-rata persentase 85,96% dengan kategori sangat positif dan dapat dibuktikan bahwa lembar kerja peserta didik (LKPD) berkategori efektif.

Abstract

The COVID-19 pandemic which has spread throughout the world in early 2020 has had an impact on teaching and learning activities in schools. The Ministry of Education and Culture and several regional officials issued policies in the form of changing teaching and learning activities to be carried out online. This study aims to determine how many factors influence students' critical thinking in mathematics in the online learning process during the covid-19 pandemic and to determine the significant factors in influencing students' critical thinking. The population in this study were senior high school students at Tabib Tabanan Jl. Bunga Kardiol Ladang Bambu and the number of samples was 29 students. The instrument in this research is in the form of a questionnaire or questionnaire. The results of this study found that the analysis of students' critical thinking in mathematics in the online learning process during the covid-19 pandemic had a positive effect. In the reliability test, physical condition has a value of 0.679%, meaning that the indicator of physical condition affects critical thinking by 67.9% and anxiety has a value of 0.675%, meaning that the indicator of anxiety affects critical thinking. So it can be concluded that the factor that influences students' critical thinking in learning mathematics is the factor that has the highest score is the physical condition factor. So it is necessary for students to continue to maintain their physical condition in learning so that the results of learning mathematics are optimal

Abstract

This development research aims to produce a product in the form of Student Worksheets (LKPD) with the Treffinger learning model on the material of valid criteria quadrilaterals and triangles. This study uses the Research and Development (R&D) development of the ADDIE model which includes five stages, namely analysis, design, product development or production, implementation, and evaluation. However, in the modification, this research only reached the implementation stage. The analysis stage is the stage of gathering information that can be used as material for making products consisting of curriculum analysis, concept analysis, and student analysis. The design stage is carried out by designing learning in the form of Student Worksheets and Learning Implementation Plans as well as data collection instruments in the form of validation sheets. In the development stage, instrument validation was carried out in the form of a questionnaire to the validator by media experts, material experts, and teachers. The results of this study produced Student Worksheets with the Treffinger learning model to improve students' understanding and creativity on valid quadrilateral and triangle material. Based on the results of the validator assessment questionnaire of the Student Worksheet, the value of the validation results by media experts is 80% in the valid category, material experts by 85% in the valid category, and the teacher by 82% in the valid category. As well as the Learning Implementation Plan obtained by 80% with a valid category. Finally, at the implementation stage, the results of the validation of student responses to the Student Worksheet with a percentage of 90% and fall into the very good category. The results of the final recapitulation of the assessment of students' conceptual understanding are 80% with high criteria. And the results of the analysis of students' creativity tests using n-gain is 0.64 in the medium category
