Abstract

This research aims to analyze the effect of the application of project-based learning models on e-learning chemical equilibrium material on learning outcomes, student activities and student responses. This type of research is a quasi-experimental with a pretest-posttest control group design. This research was conducted in January 2022. Data collection techniques were obtained by means of tests, observation sheets, questionnaires, and documentation. The population of this research is the students of class XI IPA SMA Negeri 9 Medan. The research sample consisted of 2 classes with a total of 65 students with a random sampling technique. The experimental class was given learning using a project-based learning model in e-learning, the control class was given learning using a direct learning model. This study shows the following results: (1) there is a positive effect of implementing project-based learning models on e-learning chemical equilibrium material on improving student learning outcomes, obtained tcount = 9.91 > ttable = 1.669 and class N-gain value the experimental class is 0.77 with the high category, while the N-gain for the control class is 0.56 in the medium category. (2) student learning activities in the experimental class are very positive or very good towards, the average percentage is 81.83% with the qualification "very good". (3) students in the experimental class showed a positive or good response in the learning process that took place in the classroom, the average percentage of responses was 76.55% with "good" qualifications. This shows that the project-based learning model in e-learning is good for use in the teaching and learning process.

Abstract

This study aims to determine: the feasibility of web-based diagnostic tests on electrolyte and nonelectrolyte solutions, profiles of students' conceptual understanding after using web-based diagnostic tests on electrolyte and non-electrolyte solutions, chemistry teacher responses to webbased diagnostic tests on electrolyte and non-electrolyte solutions. , student responses to web-based diagnostic tests on electrolyte and nonelectrolyte solutions. The method used in this development research is the ADDIE method which consists of 5 stages of treatment, namely analysis, design, development, implementation and evaluation. The results showed that (1) the developed web-based diagnostic test had very feasible criteria. The percentage of misconceptions on test 1 is 21.67% while test 2 is 33.33%. The percentage of not knowing the concept on test 1 is 61.33% while test 2 is 20%. The percentage of guessing on test 1 is 8% while on test 2 it is 7%. The teacher's response to a webbased diagnostic test on electrolyte and nonelectrolyte solution material obtained the percentage of presentation aspects 92%, language and content aspects 100% and benefits aspects 90%. Student responses to web-based diagnostic tests on electrolyte and nonelectrolyte solutions obtained an average percentage of 83,20% display aspect, 92,60% language and content aspect, and 87,365 benefit aspect.

Abstract

Penelitian ini bertujuan untuk mengetahui: (1) kelayakan tes diagnostik berbasis web pada materi kimia konsep redoks, (2) mengetahui profil pemahaman konsep siswa setelah menggunakan tes diagnostik berbasis web pada materi konsep redoks, (3) mengetahui respon guru kimia terhadap tes diagnostik berbasis web pada materi kimia konsep redoks, dan (4) mengetahui respon siswa terhadap tes diagnostik berbasis web pada materi kimia konsep redoks. Metode dalam penelitian ini menggunakan metode penelitian dan pengembangan atau Research and Development (R&D) dengan menggunakan model ADDIE (analisis, desain, pengembangan, implementasi dan evaluasi), penelitian ini dibatasi pada uji coba terbatas. Hasil penelitian menunjukkan bahwa tes diagnostik berbasis web pada materi konsep redoks dinyatakan layak setelah dilakukan validasi oleh ahli materi, ahli media, respon guru dan siswa. Penilaian ahli materi dengan persentase rata-rata 89,34% dengan kategori sangat layak, penilaian ahli media dengan persentase rata-rata 87,59% dengan kategori sangat layak, persentase respon guru 91,34% dengan kategori sangat menarik dan persentase respon siswa 88,84% dengan kategori sangat menarik. . Profil pemahaman konsep siswa mengalami peningkatan baik pemahaman konsep siswa perbutir soal maupun pemahaman siswa persub konsep.

This research shows the following results: (1) there is a positive influence of the application of the project-based learning model in e-learning chemical equilibrium material on improving student learning outcomes, obtained by the t-count and N-gain values of the experimental class in the high category, while the N-gain control class with medium category. (2) student learning activities in the experimental class with the qualification "very good". (3) students in the experimental class show a positive or good response in the learning process that takes place in the classroom with the qualification "good". So it can be concluded that the project-based learning model in e-learning is good for use in the teaching and learning process.
