Abstract

This study aims to analyze the effect of feedback from local content-based practicum modules on students' science process skills. Research subjects for product trials developed in this study were students of class XI using a purposive sampling technique with a sample size of 60 students. The method used in this research is quasi-experimental (quasi-experimental). The research instrument was a feedback rubric on applying a local content-based practicum module, observation sheets, and tests on the results of Science Process Skills (KPS). Data processing and analysis is carried out by comparing the initial and final science process skills scores by looking at the science process skills N-Gain score. Hypothesis testing uses the T-test to apply a local content-based practicum module on science process skills by analyzing the initial and final science process skills scores. The highest percentage result lies in the indicator of planning an experiment or investigation and using experimental tools and materials, namely 90%. There is a difference between a class that implements a local content-based practicum module and is given feedback with a class that uses a regular module for each class. The experimental class had an N-gain value of 0.75 or in the high category, while the control class had an N-gain value of 0.64 or in the moderate category. There are differences in students' Science Process Skills (KPS) using local content-based practicum modules with conventional practicum modules.

Abstract

Dalam proses pembelajaran kimia setiap siswa selalu diarahkan agar menjadi siswa yang aktif dan mandiri. Untuk menjadi siswa yang aktif sekaligus mandiri seseorang harus belajar, sehingga dapat dicapai hasil belajar yang lebih baik. Penelitian ini bertujuan untuk mendeskripsikan hubungan keaktifan belajar siswa dengan hasil belajar dan hubungan kemandirian belajar dengan hasil belajar serta hubungan bersama-sama keaktifan dan kemandirian dengan hasil belajar melalui penerapan model pembelajaran inkuiri yang diterapkan pada siswa kelas XII SMA Negeri 1 Kota Langsa. Dalam penelitian ini peneliti mengambil sampel menggunakan teknik purposive sampling yaitu kelas XII-1 karena kelas tersebut dirasa mampu mewakili karakteristik populasi yang diinginkan dengan pertimbangan bahwa kedua kelas tersebut memiliki kemampuan yang hampir sama yang didasarkan pada nilai rata-rata tes kimia. Penelitian ini merupakan penelitian eksperimen dengan model the one group pretest postes design yaitu penelitian yang diberikan untuk satu kelompok dengan memberikan pretest maupun posttest sebelum dan sesudah diberi perlakuan. Teknik pengumpulan data yang dilakukan adalah dengan tes uraian dan angket. Hasil penelitian menunjukkan bahwa terdapat hubungan positif antara aktivitas belajar dengan hasil belajar melalui pengujian hipotesis dengan koefisien korelasi (ry1) sebesar 0,405 dan terdapat hubungan positif antara kemandirian dengan hasil belajar ditunjukkan oleh koefisien korelasi (ry2) sebesar 0,518 serta terdapat hubungan positif secara bersama-sama antara aktivitas siswa dan kemandirian dengan hasil belajar dinyatakan melalui persamaan regresi Y= 15,981+0,393X1+0,271X2 dan diperoleh harga koefisien korelasi sebesar ry.12= 0,619 yang berarti tingkat hubungan (korelasinya) kuat

Abstract

Penelitian ini bertujuan untuk menganalisis kebutuhan siswa dalam pembelajaran kimia yang akan digunakan pada pembuatan rancangan perencanaan pembelajaran berbasis kurikulum 2013 dengan pendekatan saintifik. Sampel dalam penelitian ini sebanyak 5 sekolah di SMA Negeri Kota Langsa dengan melibatkan 150 orang siswa, 10 orang guru kimia, dan 5 orang kepala sekolah yang dipilih secara purposive sampling dengan mempertimbangkan keberadaan kelas IPA dan laboratorium di masing-masing sekolah. Pengumpulan data dilakukan dengan daftar isian, pedoman observasi, pedoman wawancara, dan angket, serta dianalisis secara deskriptif interpretatif, dilengkapi cross-check data dan sumber data. Kesimpulan penelitian ini: (1) telah diidentifikasi sebanyak 26 kompetensi dasar kimia yang strategis diajarkan secara terintegrasi dengan perangkat perencanaan pembelajaran baik RPP maupun silabus; (2) kurikulum 2013 memberikan peluang luas untuk mengembangkan seluruh jenis keterampilan proses sains dalam pembelajaran kimia; dan (3) sekolah menghadapi beberapa kendala dan hambatan untuk melaksanakan proses pembelajaran berdasarkan kurikulum 2013, diantaranya: keterbatasan ruang dan fasilitas laboratorium, keterbatasan alat-alat dan bahan-bahan kimia, dan ketidaktersediaan tenaga laboran.

Abstract

This study addresses the need for interactive digital assessment tools in chemistry learning, where traditional evaluation often fails to engage students or provide immediate feedback. Wordwall and Plickers were selected as platforms because both are widely accessible and classroom-friendly, yet their effectiveness in formative evaluation has not been systematically compared. The purpose of this research was to develop and evaluate interactive assessments based on these two applications for high school chemistry. A Research and Development (R&D) approach was applied by combining the Borg & Gall and 4-D models. The process included four stages: (1) Define analyzing curriculum requirements and learner needs; (2) Design and construct interactive items and adapt them to Wordwall and Plickers; (3) Develop expert validation covering content accuracy, construct clarity, and usability, followed by revisions and limited trials; and (4) Disseminate large-scale implementation with 200 tenth-grade students from public high schools in Aceh Province. Instruments consisted of expert validation sheets, student response questionnaires (attractiveness, ease of use, and learning benefit), and pretest–posttest assessments. The results showed high validity (CVR = 0.90), positive student responses, and significant learning gains for both platforms (N-gain = 0.70 for Wordwall, 0.64 for Plickers). No significant difference was found between them (p = 0.252), indicating that both tools are valid, practical, and effective for formative assessment in chemistry learning.

Abstract

The goal of this study is to develop e-learning media based on Moodle for atomic structure material, as well as to determine the feasibility of the media and the teacher's response to it. With the ADDIE method derived from Dick and Carrey, this study is included in Research and Development (R&D). Media experts, materials experts, and chemistry teachers are among the study's subjects. Expert validation questionnaires and teacher response questionnaires. The study's findings were that e-learning media based on moodle on atomic structure material had a media feasibility score of 92.8 percent with very feasible criteria and a material feasibility score of 91.7 percent with very feasible criteria. The responses chemistry teachers from Langsa Senior High School yielded an average of 87 percent with very interesting criteria. On the basis of these findings, it can be stated that the Moodle-based e-learning media designed for the atomic structure material is suitable for use in the learning process. Keywords: e-learning, learning media, moodle, development, atomic structure DOI: http://dx.doi.org/10.23960/jpmipa/v23i1.pp25-33

Abstract

The Covid-19 pandemic has plagued almost all parts of the world. The virus is transmitted by droplets, droplets, or in medical terms known as droplets when someone coughs, sneezes, or talks. There are two ways of transmitting the corona virus through droplets, namely directly and indirectly. The use of masks in preventing direct transmission of the virus is an important thing to do. Making waterproof masks made from polyester fabrics that are waterproof, splash or droplet seepage is an alternative for people to get proper masks without having to spend a lot of money. The use of a waterproof mask made from polyester cloth is not only more economical, but also more environmentally friendly because it can be reused. The simple manufacturing process and easy and inexpensive materials allow this business to be accepted by the community. This waterproof mask making training can improve the readiness of the people of Langsa City, especially Lhokbanie Village, to face the Covid-19 pandemic. The mask products produced from this training can also be used repeatedly so that they can protect the environment.
