Abstract

This study aims to determine the process and results of developing scientific-based mathematics learning worksheets that meet valid and practical criteria and test the developed worksheets' validity, practicality, and effectiveness. This research and development refer to the steps of Borg and Gall. The research subjects were grade VIII students of the Qur'an Science Middle School Minhajuth Thullab Pekalongan for the 2022/2023 academic year: data collection techniques using interviews, problem-solving ability tests, and questionnaires. The results showed that the LKPD teaching materials developed were categorized as valid (fit for use) based on the assessment of media and material expert validators. In addition, the developed scientific-based LKPD is also categorized as practical based on student assessments and responses from the mathematics teacher. Based on hypothesis testing and proportions, the scientific-based LKPD can improve problem-solving skills, but it is not yet effective because the proportion of students with good category problem-solving abilities is not more than 60% of the total number of students.

Abstract

Sel elektrolisis merupakan ilmu yang mempelajari proses perubahan energi listrk menjadi energi kimia. Materi ini memiliki konsep yang abstrak sehingga membutuhkan media pembelajaran yang dapat memvisualisasikan konsep yang abstrak kedalam bentuk yang lebih nyata. Penelitian ini bertujuan untuk mengetahui tingkat keefektivan media pembelajaran terintegrasi Augmented Reality pada materi sel elektrolisis terhadap hasil belajar peserta didik. Media pembelajaran ini sudah terbukti valid dan praktis. Metode yang digunakan pada penelitian ini adalah pra-eksperimen dengan desain one group pretest-posttest. Sampel penelitian ini terdiri dari 30 orang peserta didik kelas XII F1 di SMAN 4 Pariaman. Instrumen yang digunakan adalah tes hasil belajar berupa soal essay. Dari hasil analisis yang dilakukan didapatkan nilai N-Gain sebesar 0,71 dengan kategori tinggi. Analisis menggunakan uji-t juga menunjukkan signifikansi < 0,05 sehingga dapat disimpulkan bahwa media pembelajaran terintegrasi Augmented Reality pada materi sel elektrolisis efektif dalam meningkatkan hasil belajar peserta didik.

Abstract

The purpose of this study is to find out how mathematical communication ability of students slow in learning to solve the problem of waking flat in SD Negeri 1 Sukamaju Abung semuli north Lampung. The research method used is descriptive research using qualitative approach. The result of the research can be concluded is that the students write communication is slower to learn better than oral communication, it can be seen from the result of the answer of the student who answer the correct bigger than the student answer that correct answer in oral communication. It is said that students are slow to learn to have limitations to talk or convey ideas so they are more silent or even just smiling.
