Integrating Scientific Principles with Character Development in the Student Worksheet on Change in Matter

Integration of scientific principles with character development in the student worksheet on change in matter is crucial for fostering a holistic understanding of chemistry, aligning academic knowledge with ethical considerations, and cultivating a well-rounded educational experience. The aim of this research is to develop character-integrated teaching materials in science subjects that are suitable for use as learning media. The development of character-integrated teaching materials in science subjects uses a 4D model, consisting of four stages (define, design, develop, and disseminate). Teaching materials developed are in the form of student worksheets. Data collection technique used a questionnaire with several instruments, which are material and media expert validation instruments, student worksheets eligibility instruments, and interview instruments. Analysis of the data using the calculation of the average, percentage, coefficient of validity, and descriptively. The results of the analysis of material expert validation data, obtained a validity level of 0.825 with a very valid category. Similarly, the results of the analysis of media expert validation data, obtained a validity level of 0.735 with a very valid category. The results of the analysis of the feasibility questionnaire filled in by the teacher obtained a score of 86.25% with a very decent category. It can be concluded that the student worksheets developed is very suitable to be used as a science learning media

Problematika Kurangnya Media Pembelajaran di Sekolah

Sekolah dapat didefenisikan sebagai suatu lembaga ang digunakan sebagai sarana dan prasarana dalam mencapai pembelajaran. Dengan kata lain sekolah juga dapat diartikan sebagai tempat yang dimana sekelompok orang bahkan banyak orang untuk mencari sumber ilmu. Pendidikanerupakan wadah yang membawa manusia menjadi pribadi yang berilmu, bertakwa dan bertanggung jawab. Analisis dari penelitian ini menggunakan metode kualitatif dan menggunakan pendekatan deskriptif. Metode ini bertujuan untuk menjelaskan problematika kurangnya media belajar disekolah dan menggambarkan ketersediaan media pembelajaran disekolah. Adapun kesimpulan yang didapat dalam upaya yang dilakukan untuk mengatasi permasalahan atau problematika ini adalah memaksimalkan fasilitas sekolah dengan menganggarkan dana Bantuan Operasional Sekolah (BOS), mengupayakan kurikulum yang terbaru dan juga tenaga pendidik yang siap dan menguasai konsep pembelajaran yang menarik serta dapat membangkitkan jiwa belajar dari diri peserta didik

Praktikum Kimia SMA Kelas XI pada Materi Asam Basa Sesuai Model Discovery dan Project Based Learning

Penelitian ini dilakukan dengan tujuan mengembangkan penuntun praktikum asam basa sesuai discoverylearning dan project based learning . Pengembangan penuntun praktikum berdasarkan Langkah-langkahdiscovery learning dan project based learning. Penuntun praktikum disusun oleh penulis dan divalidasioleh dosen. Penuntun praktikum kemudian diuji cobakan ke SMA Muhammadiyah 8 Kisaran sebagailokasi penelitian. Penelitian dilaksanakan pada bulan Februari sampai Maret 2019. Penelitianmenggunakan sampel sebanyak dua kelas yaitu kelas eksperimen I yang diajar menggunakan penuntunpraktikum sesuai discovery learning dan kelas eksperimen II yang diajar menggunakan penuntunpraktikum sesuai project based learning. Angket yang diberikan kepada dosen dan guru menunjukkanhasil nilai rata-rata penuntun project based learning lebih tinggi dibandingkan dengan discoverylearning. Sedangkan peningkatan hasil belajar peserta didik yang diajar dengan menggunakan penuntundiscovery learning lebih tinggi dibandingkan project based learning yaitu masing-masing sebesar79,48% dan 60,33%. Hal ini terjadi disebabkan peserta didik belum terbiasa menyusun sendirirancangan praktikum sebagaimana yang harus dilakukan pada kelas yang menerapkan project basedlearnin

Efforts To Improve Students’ Multiple Intelligence In Dealing With Era 4.0 On The Subject of Basic Chemistry

The study on efforts to improve students' multiple Intelligence in dealing with 4.0 era in basic chemistry courses was conducted with the aim of knowing whether the questions can be developing Multiple Intelligence and whether there was an increase in Multiple Intelligence on the student's of Faculty of Teachers Training and Education at Malikussaleh University.
