Abstract

Teaching the concept of science according to nature is important and will work well if the teacher has an understanding of the nature of science. The IPA MGMP in Kaur District facilitates teachers to upgrade their knowledge and skills to improve the learning process. The topics discussed included: 1) discussing questions on the National Examination and National Science Olympiad, 2) making parameters for the Final and Middle Examination questions 3) Classroom Action Research, and 4) learning models. No one has yet discussed how to teach science in accordance with the aspects of nature of science and technology (NOST). The purpose of this training is to improve understanding of NOST aspects which consists of 4 steps: 1) equalizing perceptions of the importance of NOST, 2) Analyzing aspects of NOST 3) and increasing teacher understanding of aspects of NOST in learning. This training was conducted for 50 teachers in Kaur District through the ICARE method (Introduction, Connection, Application, Reflection and Extend). Program evaluation is carried out by adopting the CIPP design (Context, Input, Process and Product). The results show that teachers already think that science is not just a concept of chemistry, physics, and biology. In addition, the teacher's view of scientific research is not only limited to proving concepts but also involves new findings that support technological development.

Abstract

Pengetahuan tentang teknik pembelajaran yang tepat pada penyampaian konsep kimia tertentu dapat diketahui melalui proses analisis kemampuan multipel representasi kimia siswa. Penelitian ini bertujuan untuk mengetahui kemampuan interkoneksi ketiga level representasi kimia yang dimiliki siswa dalam mendeskripsikan dan menjelaskan konsep laju reaksi. Penelitian ini menggunakan desain penelitian deskripstif dengan melibatkan satu kelompok subjek. Instrumen tes terdiri dari 15 soal two tier multiple choice. Hasil penelitian menunjukkan bahwa sebesar 21.92% siswa sudah mampu mengkoneksikan ketiga level representasi kimia menunjukkan siswa sudah memiliki pemahaman konsep yang utuh. Sebanyak 25.55% siswa cenderung hanya mampu menginterkoneksikan pada dua level representasi menunjukkan siswa sudah mampu menarik kesimpulan namun kesulitan menemukan alasannya. Sebanyak 14.96% siswa cenderung lebih memahami konsep pada level representasi submikroskopik menunjukkan siswa tidak dapat menarik kesimpulan dari alasan yang diketahui dan sebanyak 37.56% siswa belum memahami maupun mengkoneksikan konsep pada tiga level representasi. Berdasarkan kemampuan interkoneksi ketiga level representasi siswa maka dapat diketahui pola interkoneksi representasi kebanyakan siswa diawali dengan representasi makroskopik lalu representasi simbolik dan terakhir representasi submikroskopik. Disarankan: penyampaian pembelajaran untuk beberapa konsep kimia harus meningkatkan pembahasan pada level representasi submikroskopik tanpa melupakan representasi makroskopik dan simbolik, pembelajaran konsep sebaiknya diawali dengan representasi makroskopik, lalu representasi simbolik dan terakhir representasi submikroskopik.

Abstract

Vitamin C, also known as ascorbic acid, is a crucial nutrient involved in a number of enzymatic processes for tissue healing. Additionally serving as an antioxidant, ascorbic acid is crucial for keeping the immune system strong. It is essential to create a quantitative analytical approach to ascertain ascorbic acid concentration in many samples since its consumption from the daily food should be in the proper quantity. Here, we present a colorimetric probe made of synthetic metal-organic frameworks (MOFs) that changes its color only when samples containing ascorbic acid are present. In this study, phenanthroline served as an organic ligand or linker while copper served as the core metal that formed bonds with it. Cu-Phen MOF color fluctuations at 410 nm (from 408 nm to 412 nm) are linearly related to variations in light absorption. Moreover, as a substitute for spectrophotometry UV-visible, we have created a digital image-based colorimetry. The Cu-Phen MOFs’ color change has the maximum slope and linearity when the blue color intensity is used. The detection limit with high precision of 4.2% under ideal circumstances was 0.1 ppm. The established approach allowed for the exact and accurate assessment of ascorbic acid in genuine samples of star fruit (Averrhoa carambola L.).
