Abstract

Penelitian ini bertujuan untuk mengetahui media pembelajaran berbasis android yang dimodifikasi pada materi laju reaksi telah sesuai dengan standar kelayakan BSNP, dan mengetahui hasil belajar siswa yang menggunakan media pembelajaran berbasis android pada materi laju reaksi lebih tinggi dari nilai KKM. Penelitian ini merupakan penelitian pengembangan dengan menggunakan model 4D (Define, Design, Develop, dan Disseminate) yang menghasilkan suatu produk yang dimodifikasi. Sampel dalam penelitian ini adalah siswa kelas XI IPA 3 yang diperoleh menggunakan teknik purposive sampling. Instrumen penelitian terdiri dari angket validasi media dan tes kognitif siswa. Data kelayakan media dianalisis secara deskriptif kualitatif dan data hasil belajar dianalisis secara statistik. Modifikasi yang dimaksud disini yakni memodifikasi media pembelajaran berbasis android menjadi lebih menarik dengan menambahkan animasi untuk memvisualkan materi teori tumbukan dan faktor-faktor yang mempengaruhi laju reaksi. Hasil penelitian menunjukkan bahwa media pembelajaran berbasis android yang dimodifikasi pada materi laju reaksi dinyatakan sangat layak dengan nilai rata-rata ahli materi 3,80; ahli media 3,64; dan praktisi pembelajaran 3,73. Hasil uji coba media menunjukkan bahwa rata-rata hasil belajar siswa setelah menggunakan media pembelajaran berbasis android lebih tinggi dari nilai KKM yakni 87,65 dan mengalami peningkatan sebesar 0,80 dengan kategori tinggi.

Abstract

Penelitian ini bertujuan untuk membahas tentang dasar alkitabiah dalam perjanjian baru mengenai pendidikan agama kristen. Metode penelitian yang digunakan adalah metode penelitian kualitatif. Hasil penelitian menunjukkan bahwa pembentukan karakter yang berkualitas harus dibangun dan dikembangkan secara sadar hari demi hari. Untuk mewujudkan pendidikan karakter yang membentuk kepribadian anak, maka perlulah kita melihat ragam tipe pola asuh orangtua dan yang terbaik adalah memberikan kebebasan kepada anak untuk menjadi dirinya sendiri, yang tentu saja butuh bimbingan dan arahan dari orangtua sebagai pendidik utama. Untuk mewujudkan tiga pilar pendidikan yang utama yakni keluarga, sekolah dan gereja, kita perlu belajar dari Teori Ekologi Bronfenbrenner. Dapat disimpulkan bahwa ketiga pusat pendidikan sama-sama memegang peran penting dalam keberhasilan pendidikan karakter pada anak dan pada dasarnya semua saling berkaitan dan saling kerjasama satu sama lain dan keluarga sebagai satuan unit sosial terkecil merupakan lingkungan pendidikan yang paling utama dan bertanggung jawab mendidik anak-anaknya.

Abstract

This research aims to develop a Discovery Learning-based E-Learners' Worksheet (E-LKPD) for thermochemistry material as an assessment of students' science skills at the high school level. With the Research and Development (R & D) approach of the 4-D model, the research involves the Defining, Designing, Developing, and Deploying stages, and uses the liveworksheet application. Validation was conducted by four validators, two for material and two for media, with average validity results of 89.5% and 81% respectively, categorized as very valid. The trial was conducted with 34 students, accompanied by a response questionnaire from two teachers and students. Teacher responses reached 94%, indicating a high level of feasibility and practicality. Learners' response reached 94.9%, indicating significant attractiveness. Measurement of students' science skills, through questions in the E-LKPD, showed an average value above the Minimum Completion Criteria (KKM) (>75). Overall, this Discovery Learning E-LKPD for thermochemistry is considered valid and effective to be used in learning chemistry at the high school level.

Abstract

This study aims to (1) find out whether the increase in student learning outcomes with the application of cooperative-based e-modules of the NHT type is higher than the learning of NHT chemistry with student reference teaching materials. (2) find out whether there is an effect of the application of e-modules based on cooperative types of chemistry. NHT on student learning outcomes. This research was carried out at the Harapan Baru Private High School Medan in November-December 2021. From the results of the study, the average pretest score for the experimental class was 36 and the control was 28,167. While the posttest average value of the experimental class was 82,667 and the control class was 77.5. The chemical normalized N-Gain value of the experimental class students was higher than the control class, namely 0.7254> 0.685 or based on the N-Gain percentage, which was 72.54% for the experimental class and 68.5% for the control class. The difference from the increase in learning outcomes from the two classes, namely 4.09%, it can be said that the application of the NHT cooperative-based chemistry e-module with student reference learning media on chemistry. In the hypothesis test, namely the t-test of one party (right side) at a significance level of 0.05, it is obtained that t_count > t_table which is 3,004> 2,002 then Ha is accepted and Ho is rejected. Thus, it can be said that there is an effect of applying cooperative-based chemistry e-modules on student chemistry learning outcomes in chemistry.

Abstract

Inappropriate teaching methods can cause student learning outcomes and interest in science subjects. Especially if the material is delivered in ways that are less interesting. One teaching method that is believed to improve learning outcomes is the experimental method. This study aims to describe the knowledge of teachers' understanding of the experimental method, the use of media, and the classroom atmosphere with the experimental method. The research method used is library research with a descriptive qualitative approach. Descriptive data was collected through written or spoken words from teachers and students observed. Relevant reading materials were selected from the library, such as books, dictionaries, journals, documents, and magazines. The criteria for selecting reading materials include novelty and relevance to the research. The results showed that the teacher was maximized in applying the experimental method on the properties of light, in accordance with the concept of knowledge about the experimental method. Thus, it can be concluded that the application of the experimental method has been optimal, allowing teachers to effectively describe the properties of light in learning at the elementary school level.
