Penelitian ini bertujuan untuk menganalisis kemampuan literasi sains fisika siswa SMP Kelas VII di Sumatera Selatan menggunakan kerangka PISA. Metode penelitian adalah deskriptif kuantitatif untuk mendapatkan gambaran kemampuan literasi sains dalam IPA (fisika) siswa tanpa memberikan perlakuan kepada siswa. Teknik pengumpulan data berbentuk tes tertulis. Penilaian disesuaikan dengan kriteria penilaian PISA. Variabel penelitian ini adalah pencapaian kemampuan literasi sains siswa pada konten fisik. Sampel diambil dengan menggunakan purposive sampling meliputi SMP N 1 kota Palembang, SMP N 1 kota Prabumulih, dan SMP N 1 kabupaten Ogan Ilir pada semester ganjil tahun ajaran 2017/2018. Hasil Penelitian diperoleh persentase pencapaian siswa yang paling tinggi pada level 2 sebesar 54,9 dan terendah pada level 5 yaitu hanya sebesar 28,1 dari skala maksimum 100. Secara keseluruhan rerata persentase hasil kemampuan literasi sains siswa SMP di Sumatera Selatan berdasarkan Kompetensi Proses Sains, yaitu 47,1. Hasil penelitian menunjukan kemampuan literasi sains siswa SMP di Sumatera Selatan secara keseluruhan ditinjau dari level soal dan kompetensi proses sains diperoleh hasil masih sangat rendah. This research aims to analyze the ability of Physics Science Literacy of Grade VII Middle School Students in South Sumatra by using the PISA Framework. The research method is a quantitative descriptive method that aims to get a picture of scientific literacy abilities in science (physics) students without giving treatment to students. The assessment is adjusted to the PISA assessment criteria. The variables of this study was the achievement of students' science literacy skills in physical content. Data collection techniques by written tests. Samples were taken using purposive sampling and the research sample are SMP N 1 kota Palembang, SMP N 1 kota Prabumulih, dan SMP N 1 Kabupaten Ogan Ilir The results of the study showed that the highest percentage of student’s achievement at level 2 was 54.9 and the lowest was at level 5, which was only 28.1 from the maximum 100 scale. While the overall percentage of the results of the scientific literacy skills of junior high school students in South Sumatra was based on Science Process Competence. that is 47.1. Based on the results of the research that has been carried out, it can be concluded that the scientific literacy skills of junior high school students in South Sumatra as a whole in terms of the level of questions and competency of science processes are still very low.
The misconception is one of the learning difficulties that occur in students when learning physics, especially the concepts of heat and temperature. One solution to overcome this is by using a textbook based on conceptual change. The purpose of the research is to develop a valid and practical conceptual change textbook based on the local wisdom of Palembang. This study uses the Rowntree research method and is combined with Tessmer's evaluation at the evaluation stage. Data was collected through a walkthrough and questionnaire. The data were analyzed by looking for the mean score obtained and then converted according to the category of expert validation results and the product practicality level. The results showed that the product developed was categorized as very valid in every aspect of content, language, and design. Meanwhile, the results of the one-to-one and small group evaluation stages each showed that it is practical. This shows that the product developed is suitable to be used and by applying appropriate learning methods expected to reduce students' misconceptions of temperature and heat.
PEMAHAMAN KONSEP DAN MISKONSEPSI MAHASISWA CALON GURU PADA HUKUM KEPLERAbstrakPenelitian ini bertujuan untuk menginvestigasi tingkat pemahaman konsep dan miskonsepsi mahasiswa calon guru pada hukum Kepler. Subjek penelitian adalah 68 mahasiswa peserta mata kuliah Ilmu Pengetahuan Bumi dan Antariksa (IPBA). Sampel dipilih berdasarkan teknik persampelan purposif. Pengumpulan dan analisis data menggunakan mix method, gabungan penelitian kuantitatif dan kualitatif. Instrumen yang digunakan adalah two-tear test berupa penyusunan peringkat dan pemberian alasan. Analisis dilakukan terhadap dua lapis data yang dianalisis secara bersamaan berdasarkan tingkat pemahaman konseptual. Hasil penelitian menunjukkan tingkat pemahaman konsep bervariasi dengan dominasi Paham Sebagian dan Miskonsepsi (33,82%) untuk Hukum II Kepler dan Paham Sebagian (42,65%) untuk Hukum III Kepler. Penelitian mendapatkan 14 bentuk miskonsepsi berkaitan dengan kecepatan, perioda, dan jarak orbit benda langit mengitari bintangnya dan pengaruh massa serta bentuk orbit ter-hadap variabel kecepatan, perioda, dan jarak orbit. Sebelas miskonsepsi belum dilaporkan pada penelitian sebelumnya. Pembelajaran tradisional tidak berhasil dalam meningkatkan pemahaman konsep karena berorientasi pada penguasaan rumus dan penghafalan fakta. Perlu inovasi pembelajaran untuk meningkatkan penguasaan konsep.Kata kunci: pemahaman konsep, miskonsepsi, hukum Kepler, IPBAAbstractThis study was aimed at investigating the level of understanding of the concepts and misconceptions of teacher students in Kepler's law. The research subjects were 68 students participating in the Earth and Space Sciences (ESS) course. The sample was chosen based on the purposive sampling technique. The collection and analysis of the data used a mixed-method, a combination of quantitative and qualitative research. The instrument used was a two-tear test in the form of ranking and explanation. The analysis was carried out on two layers of data which were then analyzed simultaneously based on an analysis of the level of conceptual understanding. The results show that the level of concept understanding varied with the dominance of Partial Understanding and Misconception (33.82%) for Kepler's Law II and Partial Understanding (42.65%) for Kepler's Law III. The study found 14 forms of misconception related to the velocity, period, and orbital distance of celestial bodies around the star and the effect of mass and orbital shape on variable velocity, period, and orbital distance. Eleven misconceptions have not been reported in previous studies. The failure of conventional learning in improving understanding of concepts is due to the application of traditional approaches that are oriented towards mastering formulas and memorizing facts. Learning innovation is needed to improve the mastery of concepts.
The research aims to develop a fluid dynamic learning video-based contextual in water areas that valid and practical. This research is a development study using the Rowntree model, which consists of planning, development, and evaluation stages. The evaluation phase uses the Tessmer evaluation only to the small group evaluation stage. The one to one and small group evaluation stages will be carried out at SMA Negeri 1 Air Saleh in the even semester 2018/2019. Data collected through a walkthrough and questionnaire. The data is then analyzed by determining the mean percentage then converted to get the conclusion of validity and practicality of the video developed. The research conducted concluded that a fluid dynamic learning video-based contextual in water areas have been successfully developed with a percentage of 94% and very practical with a percentage of 87%, making it feasible to use. The product developed can then be used by the teacher to teach the concept of dynamic fluid, especially in schools in water areas, so that students can understand the concept of dynamic fluid based on the surrounding environment.
This study aims to develop a valid and practical e-learning model for critical thinking skills using the moodle platform in the lesson of electromagnetic induction. Dick and Carey instructional design model is applied for the product development—which consists of nine stages, (1) instructional goals identification, (2) instructional analysis, (3) learners and contexts analysis, (4) objective performance arrangement, (5) assessment instruments development, (6) instructional strategy’s plan, (7) instructional material selection, (8) preparation for conducting a formative evaluation of the instruction, and (9) revise instruction. The results reveal the moodle design is valid and practical regarding expert and user perspectives, respectively. Besides, there is an improvement of student’s critical thinking skills according to the obtained n-gain score, which stands for 0.38.
