PENGEMBANGAN LKPD BERBASIS PENDEKATAN CONTEXTUAL TEACHING LEARNING MATERI GEOMETRI MATEMATIKA KELAS IV SEKOLAH DASAR

Berdasarkan observasi awal diperoleh dari SD Negeri 90 Palembang yaitu khususnya siswa kelas IV bahwa rata-ratanilai peserta didik di SD Negeri 90 Palembangpada materi geometri masih dibawah KKM “75”. Sedangkan nilai rata-rata peserta didik pada materi geometri di SD Negeri 90 Palembang “70”, dikarenakan pembelajaran masih berpusat pada guru, dan peserta didik kurang memahami konsep yang diberikan. Oleh karena itu, pendidik harus menciptakan pembelajaran yang menyenangkan untuk peserta didik, misalnya dengan mengembangkan LKPD yang menarik. Maka peneliti mamadukan LKPD dengan berbasis Contextual Teaching Learning. Pendidik hanya mengandalkan buku paket dari pemerintah, selain itu juga keterbatasan bahan ajar yang dapat memfasilitasi atau mendorong berkembangnya kemampuan peserta didik. Penelitian ini merupakan jenis penelitian Research and Development (R&D). Penelitian ini menggunakan model ADDIE yang terdiri dari lima tahapan yaitu Analysis, Design, Development, Implementation, and Evaluation. Subjek dalam penelitian ini ialah peserta didik kelas IV SD Negeri 90 Palembang. Teknik pengumpulan data yang digunakan yaitu angket. Teknik analisis data yang digunakan yaitu analis validasi, analisis kepraktisan dan analisis keefektifan. Proses analisis validasi ini divalidasi oleh 4 ahli/pakar yaitu ahli materi, ahli media, dan ahli bahasa dengan rata-rata 93,88% dikategorikan sangat valid. Proses analisis kepraktisan dengan mengujicobakan kepada peserta didik pada tahap uji perorangan (one to one) menggunakan 3 peserta didik dan tahap uji kelompok kecil (small group) menggunakan 8 peserta   didik, setelah diujicobakan mendapat skor rata-rata 91,33 %. Sehingga dikategorikan sangat praktis. Proses analisisis keefektifan diujicobakan oleh peserta didik melalui uji lapangan (field test) yaitu seluruh peserta didik di kelas, setelah diujicobakan mendapat Gain-score rata-rata 0,72 dikategorikan sangat efektif. Dengan demikian dapat disimpulkan bahwa LKPD berbasis pendekatan Contextual Teaching Learning dikategorikan sangat valid, praktis dan efektif. Dengan dilakukannya penelitian ini dalam mengembangkan suatu produk yaitu Lembar Kerja Peserta Didik (LKPD) merupakan hal sangat penting didalam dunia pendidikan dikarenakan produk yang dikembangkan didalam penelitian ini akan terus mengalir dan bermanfaat untuk anak-anak yang akan menempuh jenjang  sekolah khususnya kelas IV Sekolah Dasar. Peneliti juga membuat pembelajaran yang menyenangkan sehingga materi-materi yang terdapat didalam Lembar Kerja Peserta Didik (LKPD) yang sudah dikembangkan peneliti berisi materi dalam gambaran bentuk yang nyata yang terdapat dalam kehidupan sehari. Hal ini juga akan mempermudah anak-anak dalam memahami materi atau bentuk soal-soal yang akan dikerjakan

PENGEMBANGAN MEDIA TOUR THE ZOO PADA PEMBELAJARAN IPA HARMONI DALAM EKOSISTEM KELAS V SD

There are still many teachers who use the lecture method and lack of interesting learning media so that learning becomes monotonous and boring. This type of research and development of learning media uses the Research and Development method or (R&D) with the ADDIE development model which has five stages, namely analysis, design, development, implementation, and evaluation. Questionnaires consist of media validation questionnaires, material validation, language validation, teacher responses, and student responses. The subjects in this study involved fifth grade students of SDN 13 Rambutan. Based on the results of the development and research conducted on the development of Tour The Zoo media on learning science harmony in the ecosystem of grade V SD, the validation results obtained a percentage of 84.8% for the total validation of media, material and language. For practicality, it obtained a percentage of 96% which was obtained from the value obtained from the teacher response questionnaire instrument, one to one (one-on-one trial) then small group (small group trial). Based on the data, the results show that Tour The Zoo media is categorized as very valid and very practical to use in the learning process of science in grade V SD on the material of harmony in the ecosystem. This learning media can be applied by teachers to help students learn

PENGEMBANGAN BAHAN AJAR SIKLUS AIR BERBASIS FLIPBOOK DIGITAL PADA KELAS V SEKOLAH DASAR

The use of learning media, especially digital teaching materials for water cycle material in class V, is less than optimal. Therefore, it is necessary to develop digital flipbook-based water cycle teaching materials. This study aims to determine that digital flipbook-based water cycle teaching materials in grade V elementary schools have met the criteria of validity and practicality. Criteria for validity are carried out by material experts, media experts and linguists. While practicality is done by the response of students through a questionnaire sheet. This research uses the R&D method with the ADDIE development model which consists of five stages, namely analyzie, design, development, implementation, and evaluation. The research was conducted at SD Negeri 95 Palembang. The results of validation by validators obtained an average score of 85.46% with a very valid category. The results of the practicality of the learner response questionnaire were in the very practical category with an average value of 83.25%. From the results of these data it can be concluded that the development of digital flipbook-based water cycle teaching materials in grade V elementary schools is categorized as very valid and very practical so it is feasible to use in achieving learning objectives at school
