Abstract

Penelitian ini bertujuan untuk mengetahui skala kesulitan belajar siswa dan tingkat pemahaman siswa pada topik Struktur Atom dan Sistem Periodik Unsur berdasarkan hasil angket dan asesmen formatif di SMAN 6 Malang, melibatkan 32 siswa kelas X-7 sebagai sampel penelitian. Instrumen penelitian berupa tes pilihan ganda dengan kode A dan kode B yang telah memenuhi kriteria valid dengan nilai validitas butir soal berdasarkan analisis point biserial berkisar antara 0,311 hingga 0,860 dan nilai reliabilitasnya berdasarkan nilai Cronbach’s Alpha yaitu 0,880 untuk kode A dan 0,846 untuk kode B. Hasil penelitian menunjukkan bahwa sebagian besar siswa kelas X-7 mengalami kesulitan dalam memahami konsep-konsep materi Struktur Atom dan Sistem Periodik Unsur, terlihat dari hasil angket kesulitan belajar dan nilai rata-rata siswa yang masih berada di bawah KKM. Analisis lebih lanjut mengungkapkan bahwa siswa kesulitan dalam menghubungkan konsep-konsep abstrak, seperti konfigurasi elektron dengan sifat-sifat unsur, serta menunjukkan kecenderungan bergantung pada hafalan daripada pemahaman konsep yang mendalam. Sebanyak 43,7% siswa berada pada kriteria tingkat pemahaman yang kurang, menunjukkan perlunya peningkatan strategi pembelajaran untuk memperbaiki pemahaman siswa terhadap materi kimia.

Abstract

Educational websites utilize information and communication technology to facilitate active learning for students, unrestricted by time and location. As a form of digital media, websites offer numerous benefits, such as the capacity to host extensive materials, making them ideal supplementary resources for students. The flexibility of websites allows for easy access without concerns about time constraints or high costs. One effective platform for creating educational websites is Google Sites, which is user-friendly, efficient in internet data and storage usage, and requires no complex programming skills. Furthermore, Google ensures security for its users and offers free website development. These sites can be designed to feature comprehensive content and visually appealing layouts to boost student engagement. The accessibility and advantages presented by Google Sites address the challenge of low student interest in chemistry, making its development a suitable solution. This research is classified as research and development (R&D), using the ADDIE instructional development model which aims to produce products in the form of google site-based learning media on the material of the mole concept. The study's findings indicated a validation score of 90.26% from subject matter experts, categorized as very feasible/valid, and 89.67% from media experts, also deemed very feasible/valid. Additionally, a readability assessment of the learning website achieved a score of 86.11%, meeting easy-to-understand criteria. The website has been implemented in classroom learning. The results of the analysis of student scores before and after the test showed an increase in learning interest. Although the increase is relatively low, with an N-Gain value of 0.21, these results indicate the potential for further improvement if the research is developed more optimally. Thus, it can be concluded that Google Sites-based learning media on the material of the mole concept has the potential to increase student interest in learning.

Abstract

Independence in learning can be built through self-regulated learning. The low of student self-regulated learning occurred in students of class X.1 State Senor High School (SMAN) 6 Malang. So far, research related to improving students' self-regulated learning has only focused on strategies without supporting learning media. Therefore, it is necessary to conduct a research and development study on instructional media that can enhance students' self-regulated learning. The purpose of this study is to develop a G-Sites-based learning media integrated with the TGT type of cooperative learning model to improve students' self-regulated learning. This study employs the ADDIE development model, which consists of the stages of analysis, design, development, implementation, and evaluation, carried out systematically. The sampling technique used in this study is purposive sampling, as the research is based on a problem related to low self-regulated learning identified in class X.1. The subjects of this research were students of class X.1, students of class XI as respondents of readability test, and chemistry teachers of SMAN 6 Malang as validators of material and media experts. Data analysis was carried out using a mixed-method approach, both qualitative and quantitative, employing descriptive and percentage analysis techniques. The developed product was declared valid and feasible to use with percentage results on the graphic design aspect of 83%; presentation and use of media 80%; suitability of material 97%; presentation of material 93%; language 88%; suitability of syntax 97%; and suitability of self-regulated learning 100%. The implementation of G-Sites is proven to increase students' self-regulated learning by 14.5%.
