Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh pembelajaran praktikum kimia berbasis inkuiri terbimbing terhadap keterampilan menyimpulkan siswa pada materi kelarutan dan hasil kali kelarutan. Desain penelitian yang digunakan adalah eksperimen semu dengan instrumen berupa tes untuk mengukur keterampilan menyimpulkan. Data hasil penelitian dianalisis menggunakan analisis statistik. Hasil analisis menunjukkan bahwa siswa yang mengikuti praktikum dengan metode inkuiri terbimbing memiliki keterampilan menyimpulkan yang lebih tinggi, dengan persentase nilai sebesar 81,9%, dibandingkan dengan siswa yang mengikuti metode praktikum verifikasi yang memperoleh nilai sebesar 73,6%. Temuan ini mengindikasikan bahwa pembelajaran praktikum kimia berbasis inkuiri terbimbing lebih efektif dalam meningkatkan keterampilan menyimpulkan siswa pada materi kelarutan dan hasil kali kelarutan.

Abstract

This research aims to examine the effect of using an Android application based on Augmented Reality (AR) in practical activities on students' science process skills. The research used a pre-experimental design with a one-group pretest-posttest design involving 35 students at MAK Madani Manado. The research results show a significant increase in students' science process skills, which can be seen from the average pretest score of 52.48 and posttest of 86.69. This increase reflects the effectiveness of using AR-based applications in helping students improve their skills in observing, classifying, formulating hypotheses, designing experiments, processing data, and drawing conclusions. AR applications provide a more interactive learning experience by allowing students to visualize abstract concepts in a real way so that chemistry learning becomes more interesting and meaningful. These findings provide a positive contribution to the development of more innovative and contextual chemistry learning strategies, as well as offering solutions to overcome limited laboratory facilities in schools. The use of AR applications in chemistry learning also supports the creation of learning experiences that are relevant to learning needs in the digital era, thereby increasing student motivation and involvement in learning.

Abstract

This study aims to develop a digital textbook based on multiple representations on chemical bonding as a digital learning resource for 10th-grade high school students. Product development was conducted using the Research and Development (R&D) method with the ADDIE model. Product validation involved media experts, material experts, and field trials with students using a Likert scale questionnaire instrument of 1–5. The assessment results showed that the digital textbook received a "Very Good" category from media experts (86.23%), material experts (85.20%), and student responses (94.35%). This digital textbook integrates three levels of chemical representation: macroscopic (real phenomena), microscopic (particle structures), and symbolic (chemical equations) through interactive features such as molecular animations, simulations, explanatory videos, and evaluation quizzes. The product meets the standards of the Independent Curriculum, has an intuitive user interface, and can be accessed across multiple devices. In conclusion, this digital textbook based on multiple representations is suitable for use as a digital learning resource for 10th-grade high school students on chemical bonding.
