AbstrakPenelitian bertujuan untuk mendeskripsikan pemahaman konsep IPA siswa SMP dan kemampuan menalar dalam membentuk konsep melalui pembelajaran problem solving. Jenis penelitian adalah deskriptif kuantitatif. Teknik pemilihan sampel dilakukan secara purposive sampling menyesuaikan dengan jenjang umur studi PIRLS, TIMSS dan PISA. Sampel penelitian adalah siswa kelas VII berjumlah 66 orang berasal dari SMP unggulan di Banjarmasin. Data penelitian diperoleh menggunakan instrumen tes. Teknik analisis data dengan cara melihat perkembangan skor n-gain dari pemahaman konsep dan rata-rata skor kemampuan menalar siswa pada tiap pertemuan. Hasil penelitian diperoleh rata-rata pemahaman konsep siswa sebelum pembelajaran adalah 52,28 tergolong kategori kurang baik, skor setelah pembelajaran adalah 77,40 tergolong kategori baik. Kemampuan menalar siswa dalam mengamati objek, abtraksi dan diskriminasi, dan penetapan aturan masalah tergolong sangat baik. Pemahaman konsep IPA dan kemampuan menalar berkembang dengan model problem solving. Perkembangan terjadi karena siswa terlatih dalam proses memilah dan menghubungkan pengetahuan deklaratif dan prosedural ketika menyelesaikan masalah pembelajaran.
Scientific literacy is the ability to explain phenomena and solve problems using scientific knowledge. Despite being an important factor in the scientific and technological advancement of society, students worldwide struggle to attain the skills necessary to demonstrate competency in scientif literacy. This study examines the capacity for a cognitive style-based learning strategy (CSBLS) to improving students' environmental knowledge and scientific literacy. 55 students from two Indonesian state junior high schools (SMPN) participated in the research; 30 students from SMPN 6, Banjarmasin and 25 students from SMPN 21, Banjarmasin. The CSBLS was applied during six classroom meetings over a three week period using a group pre-test and post-test on the topic of environmental pollution. The study concluded that the CSBLS was able to improve students' environmental knowledge and scientific literacy. In addition, the learning strategy supported students different cognitive styles (Field Independent/FI and Field Dependent/FD, although scaffolding was still needed for tasks that required more complex thinking such as scientific literacy, particularly for FD. This research indicates that a CSBLS has the potential to improve students' environmental knowledge and scientific literacy throughout the learning process.
Abstract-This research intended to develop a prototype of teaching and learning materials on natural science topic of junior high school. The development of learning materials was conducted by using Dick and Carey's Research & Development model. Teaching and learning materials are included syllabus, lesson plan, worksheet, student's book, test of learning outcome. This study is a deep evaluation to find weakness of prototype from the student's perspective and enhancements to make it better. Research subjects were 32 junior high students taken by simple random sampling. Data collection technique was observation of student's activity and evaluation of worksheets. The instruments included questionnaire, observation sheets and students' worksheets. The result showed that the semisummative evaluation of the prototype was success to create a feasible prototype. Teachers can apply well, but students had a bit of difficulties. It was concluded that the weakness of the teaching and learning material prototype from the viewpoint of the students are activities work to do problem solving strategies on the experiment. The teaching and learning material prototype still needs to be enriched in terms of operational definitions of concepts, the tools, and tool laboratory functions as well as a glossary.
Schools in Indonesia have been conducted environmental education programs through both curriculum activities and schools’ environmental programs. However, there was no sufficient data about the effectiveness of the programs. This study aims to identify the junior high school students’ caring attitudes to the wetland environment (CATWE) as the education outcome. The Six Junior High Schools were chosen as probability sampling areas classified as urban, central, and rural areas schools of Banjar District with total samples of 354 students aged 12-14 years. The CATWE data were collected using a valid and reliable questionnaire. This study found that most of the students care for the wetland environment. There were no differences in the CATWE of the three school areas. These findings indicate that the school area and the level of the “Adiwiyata†program were not the primary determining variable of environmental caring attitude education effectiveness. The highest score of the CATWE indicator was responsible; meanwhile, the lowest was hard work. Even though all the indicators have reached a care category. It is necessary to thoroughly investigate the effectiveness of the school environmental program “Adiwiyata,†outside classroom activity, and family role in environmental education.
Hal penting yang ingin ditingkatkan berkenaan pembelajaran yaitu methods dan insight. Metode meliputi pengetahuan profesionalisme guru yang akan terlihat dalam rancangan pembelajaran dan penerapannya. Insight merupakan hal-hal yang tidak nampak dalam rancangan pembelajaran, unpredictable, terjadi spontan dalam pembelajaran, dan guru harus mengambil keputusan (decision). Tujuan penelitian ini adalah peningkatan pengelolaan pembelajaran secara reflektif, dengan cara menganalisis pembelajaran berdasarkan salinan percakapan selama proses pembelajaran. Oleh karena itu dilakukan penelitian 'Penerapan Transcript Based Lesson Analysis (TBLA) Sebagai Upaya Peningkatan Pembelajaran Kimia Di SMA Negeri 7 Banjarmasin'. TBLA merupakan salah satu cara dalam Lesson Analysis yang merupakan bagian dari Lesson Study. Adapun langkah-langkah penelitian ini yaitu: (1) Merencanakan research lesson, (2) Implementasi pembelajaran, meliputi: observasi, refleksi, transkripsi (instant transcript), (3) Analisis pembelajaran melalui full transcript yang diperoleh melalui rekaman audio dan video. Penelitian dilaksanakan di kelas 12 MIPA-2 SMAN 7 Banjarmasin secara bersiklus. Berdasarkan hasil TBLA siklus 1 dan 2 terlihat kecenderungan transkrip percakapan secara klasikal masih didominasi oleh guru. Adapun dampak positif penerapan Lesson study antara lain: membantu guru mengkritisi pembelajarannya berdasarkan hasil reflektif, membantu guru dalam memantau aktivitas peserta didik secara lebih detail, karena bantuan observer dan meningkatkan kolaborasi guru dalam team teaching.
