Abstract

Molecular geometry is a subject that many students find difficult to understand. This is because students have to imagine those molecules in order to fully understand the content. To help students understand those concepts, the learning meda that can be seen directly is needed. This study aims to produce students’ worksheet (LKPD) on molecular geometry and a Hy-Kit (Hybridization Kit) based on discovery learning. In addition, the validity and students’ responses also measured towards those LKPD and Hy-Kit. The LKPD was arranged based on discovery learning model and equipped with Hy-Kit. The research method is a research and development using the ADDIE model. The test of the product was carried out twice. These are group tests (limited tests) and field tests. The result of the study that discovery learning-based LKPD and Hy-Kit had a validity level of materials aspect, the level of media aspect and level of bahasa aspect were k=1.00 with very high category. The response of students for the group test and for the field test were k= 0.89 and k=0.90 which means very good/valid/very interested. Both results indicates that the LKPD and Hy-Kit are valid, feasible and ready to use in the learning process

Abstract

Pemahaman konsep sangat penting bagi siswa agar mengerti pada materi yang dipelajari dan lebih mudah untuk mengikuti pembelajaran pada tingkatan yang lebih tinggi. Struktur atom memuat materidasar kimia untuk memahamimateri kimia yang lebih tinggi. Penelitian ini bertujuan untuk mendeskripsikan pemahaman konsep siswa pada materi Struktur Atom. Keterbaharuan dalam peneltian ini yaitu menggunakan indikator pemahaman menurut Anderson & Krathwohl dan kriteria pemahaman yang diadaptasi dari penelitian Akkuzu dan Uyulgan (2016). Metode penelitiannyaadalah deskriptif kuantitatif yang dilaksanakan di SMA Negeri 01 Ngabang, sampel penelitian adalah 35 orang siswa kelas X MIPA A.Teknik pengumpulan data yaitu teknik pengukuran berupa tes tertulisberbentuk esai. Dilakukan analisis data secara deskriptif kuantitatif. Hasil penelitianmenunjukkan sebanyak 52% siswa yang menjawab dengan benar pada konsep partikel penyusun atom yang menunjukkan kategori Menunjukkan Pemahaman (MP) dan sebanyak 73% siswa tidak memberikan tanggapan pada konsep sifat keperiodikan unsur yang menunjukkan kategori Tidak Ada Tanggapa (TA).Kata Kunci: deskripsi, pemaham konsep, struktur atomDescription of Understanding Concepts in Atomic Structure Matter in Class X of SMA Negeri 01 NgabangAbstractConceptual understanding is very important for students to understand the material being studied and it is easier to follow learning at a higher level. Atomic structure contains basic chemical material to understand higher chemical matter. This study aims to describe students' conceptual understanding of Atomic Structure material. The update in this research is to use understanding indicators according to Anderson & Krathwohl and understanding criteria adapted from research by Akkuzu and Uyulgan (2016). The research method was descriptive quantitative which was carried out at SMA Negeri 01 Ngabang, the research sample was 35 students of class X MIPA A. The data collection technique was a measurement technique in the form of a written test in the form of an essay. Data analysis was carried out in a quantitative descriptive manner. The results showed that as many as 52% of students answered correctly on the concept of atomic composing particles which indicated the Demonstrated Understanding (MP) category and as many as 73% of students did not respond to the concept of periodicity of elements which indicated the No Response (TA) category.
