Abstract

The concept is an understanding of an individual or a group of people who is expressed in the form of a meaning that produces knowledge. Misconceptions of students that appear continuously will interfere with the formation of scientific conceptions and can affect student learning outcomes. Therefore it is necessary to analyze the misconceptions of students. One of the diagnostic tests that can be used is a two-tier multiple choice test or known as a two-tier multiple choice, the first level is the question being tested while the second level contains the reasons for the answer to the first level. This study aims to analyze misconceptions and determine the percentage of students' misconceptions on hydrocarbon material using descriptive methods. The subjects were 27 students of class XI IPA 2 in SMA Pertiwi 1 Padang. The research instrument was a Two Tier Multiple Choice diagnostic test by dividing students' conceptual understanding into the categories of conceptual understanding, misconception, and conceptual misunderstanding. The results showed that the percentage of students' conceptual understanding in the concept understanding category was 31%, misconception was 36%, and did not understand the concept by 34% on hydrocarbon material. Students' misconceptions on hydrocarbon material at SMA Pertiwi 1 Padang were categorized as moderate. Konsep merupakan pemahaman individu atau sekelompok orang yang diungkapkan dalam bentuk pengertian yang menghasilkan suatu pengetahuan. Miskonsepsi peserta didik yang muncul terus menerus akan mengganggu pembentukan konsepsi ilmiah dan dapat mempengaruhi hasil belajar peserta didik. Oleh sebab itu perlu dilakukan analisis miskonsepsi peserta didik. Salah satu tes diagnostik yang dapat digunakan adalah tes pilihan ganda bertingkat dua atau dikenal sebagai two-tier multiple choice, tingkat pertama merupakan pertanyaan yang diujikan sedangkan tingkat kedua berisi alasan atas jawaban pada tingkat pertama. Penelitian bertujuan untuk menganalisis miskonsepsi dan menentukan persentase miskonsepsi peserta didik pada materi hidrokarbon dengan metode deskriptif. Subjek penelitian ini adalah peserta didik kelas XI IPA 2 di SMA Pertiwi 1 Padang yang berjumlah 27 orang. Instrumen penelitian berupa tes diagnostik Two Tier Multiple Choice dengan membagi pemahaman konsep peserta didik dalam kategori paham konsep, miskonsepsi, dan tidak paham konsep. Hasil penelitian menunjukkan bahwa persentase pemahaman konsep peserta didik pada kategori paham konsep sebesar 31%, miskonsepsi sebesar 36%, dan tidak paham konsep sebesar 34% pada materi hidrokarbon. Miskonsepsi peserta didik pada materi hidrokarbon di SMA Pertiwi 1 Padang termasuk kriteria sedang.

Abstract

The 2013 curriculum requires the application of scientific approach in learning. As many as 53.84% of the 13 chemistry teachers in West Sumatra experienced difficulties in implementing scientific approach cause the limited time allocation and low student learning outcomes.This study aims to describe learning outcomes, misconceptions, and inhibitory materials and the relationship between the implementation of the scientific approach to the chemical bonding material. This descriptive research uses Mixed Method with Convergent mixed parallel design. The population is the students of X class SMA in Pasaman Regency with sample of class X MIPA. Data were collected using document analysis, observation methods, and tests. The data were analyzed using the Miles & Huberman analysis technique, normality test, and correlation test. The results of this study indicate that the scientific approach has not been implemented properly. Student learning outcomes <4% and as many as 61 types of misconceptions were identified cause the presence of inhibitory materials such as atomic stability for chemical bonds, PEI and PEB for molecular geometry, and Lewis structures for intermolecular interactions. The results of the analysis concluded that there was a correlation between the implementation of the scientific approach and learning outcomes with a significance of 0.00 and a correlation coefficient of 0.617. So, the implementation of the scientific approach affects student learning outcomes.

Abstract

The COVID-19 pandemic has affected the education system in Indonesia, especially in the implementation of learning. Due to a lack of time, learning using a scientific approach does not go well. One way to overcome time constraints is to use discussion techniques in learning. Therefore, research is needed that aims to compare student learning outcomes using the Guided Inquiry and Discovery Learning learning models using the Buzz Group discussion technique on acid-base titration material. The research population was all students of class XI, IPA MAN 1, Kota Bukittinggi, consisting of 4 classes. The sample is determined by the random sampling technique. Class XI IPA 1, the experimental class, uses the guided inquiry model, and class XI IPA 2, the experimental class, uses the guided discovery model with the buzz group discussion technique. Posttest data collection was done in the form of essay questions, with a total of 65 questions. The results showed that there were differences in the average scores of the two experimental classes. Based on the results of hypothesis testing, it was concluded that learning using the guided inquiry and guided discovery models with the buzz group discussion technique differed significantly.

Abstract

Materi Kesetimbangan Kimia yang harus dipahami dengan pemikiran tingkat tinggi yang salah satunya dapat dipahami dengan pemikiran secara kreatif. Untuk itu diperlukan Penelitian yang bertujuan untuk menyediakan asesmen keterampilan berpikir kreatif materi kesetimbangan kimia yang valid dan reliabel sehingga dapat digunakan untuk mengukur kemampuan berpikir kreatif siswa. Jenis penelitian yang digunakan pada penelitian ini yaitu penelitian atau Research and Development (R & D) dan Metode yang dipakai adalah metode Mc. Intire dalam Mulyatiningsih. Mc Intire terdiri dari 10 tahapan, yaitu (1) Mendefinisikan kompetensi, peserta tes dan tujuan tes, (2)Mengembangkan rencana uji, (3) Menyusun item tes, (4) Menulis instruksi administrasi, (5) Melakukan uji coba, (6) Melakukan analisis item, (7) Merevisi tes, (8) Validasi tes, (9) Mengembangkan Norma, (10) Melengkapi tes manual. Dalam Menyusun tes dilakukan validasi menggunakan CVR, Sedangkan Uji Empirin menggunakan SPSS. Hasil Analisis validitas menggunakan CVR pada penelitian ini menunjukan nilai yang lebih besar dari 0,736 sehingga dapat dikatakan valid.

Abstract

Materi asam basa merupakan salah satu pelajaran kimia yang dipelajari pada fase F. Hasil wawancara beberapa guru kimia di Padang mengemukakan proses pembelajaran menggunakan buku teks Kemendikbud sebagai salah satu bentuk penerapan Kurikulum Merdeka. Buku teks harus memuat konten yang relevan dengan tujuan pembelajaran dan mengikuti kurikulum. Namun, cakupan materi asam basa pada buku teks Kemendikbud masih perlu dilakukan peninjauan. Tujuan penelitian ini untuk mendeskripsikan kesesuaian struktur konten Kurikulum Merdeka pada materi asam basa berdasarkan taksonomi Bloom Revisi, taksonomi Simpson dan Dyers serta taksonomi Anderson dan Krathwol dan buku ajar kimia. Jenis penelitiannya adalah deskriptif kualitatif dengan desain Model of Educational Reconstruction (MER). Hasil analisis struktur berdasarkan aspek pengetahuan, keterampilan dan sikap sesuai dengan standar yang ditetapkan. Hasil analisis konten materi asam basa pada buku teks Kemendikbud terdapat beberapa konsep yang tidak sesuai terhadap buku teks Universitas yaitu beberapa sub materi dibahas kurang rinci, bahkan ada yang tidak dibahas; dan terdapat beberapa ketidaksesuaian urutan sub bab antara buku teks Kemendikbud dengan buku teks Universitas.
