Abstract

This study aims to determine: (1) the feasibility of interactive learning media based on Adobe Flash CS6; (2) differences in motivation and learning outcomes using interactive learning media based on Adobe Flash CS6 and using chemistry learning media on the internet; (3) the influence of motivation on learning outcomes. This study uses R&D ADDIE (Analysis, Design, Development, Implementation, and Evaluation) method. The population was all students of second grade at SMA Negeri 1 Padangsidimpuan. The samples were taken by using purposive sampling, there were 60 students from two classes at the second grade. The data collection instruments were tests and questionnaires. The results: (1) the feasibility of interactive learning media based on Adobe Flash CS6 shows the mean is 4.5, which is very suitable to use; (2) motivation and learning outcomes using interactive learning media based on Adobe Flash CS6 shows 94.7% and 87.17 which is higher than the motivation and learning outcomes using chemistry learning media on the internet, namely 88.5% and 79.67; (3) the effect of learning motivation in learning outcomes using interactive learning media based on Adobe Flash CS6 is 18.6%. The results of this study is used as an input for teachers and prospective teachers in using interactive learning media to create fun learning and increase motivation that will have an impact on learning outcomes.

Abstract

Abad 21 yang sangat terkenal dengan istilah dunia teknolgi industri telah memberikan tuntutan kepada semua bidang dan pihak agar dapat berinovasi, masif dan dapat memanfaarkan teknologi dengan baik. Dalam bidang pendidikan, digital-age atau masa digital dalam dunia pendidikan menuntut kualitas pembelajaran yang harus meningkat dengan pemanfaatan media digital sebagai upaya mendapatkan informasi keilmuan agar dapat mencapai tujuan pembalajaran yang diharapkan. Media digital mampu membantu menyajikan materi pembelajaran secara kontekstual maupun audio visual sehingga pembelajaran dapat berlangsung dengan menarik, interaktif dan partisipatif. Peneliti memiliki tujuan yaitu menilai kebutuhan, kelayakan serta respon mahasiswa terhadap chemistry learning website pada pembelajaran kimia, Penelitian ini menggunakan penelitian pengembangan dengan model ADDIE yang diharapkan menghasilkan produk yang berkualitas dan baik. Subjek yang diteliti adalah mahasiswa pendidikan kimia yang menempuh mata kuliah kimia dasar. Hasil penelitian menunjukkan bahwa media pembelajaran chemistry learning website yang dikembangkan layak/valid untuk digunakan dengan nilai valid oleh ahli materi sebesar 0,84 dan ahli media sebesar 0,85 serta angket respon yang disebarkan diperoleh bahwa kriteria keidealan media dinyatakan sangat baik dengan skor rerata akhir (x) sebesar 38,6.

Abstract

The lack of variety in instructional media can be a starting point for the difficulty in creating an effective and enjoyable learning environment, particularly in chemistry subjects. The concepts in chemical bonding are abstract, making them difficult to apply contextually. Based on these issues, the researchers developed CHEMILARD (Chemistry Flashcard) media using augmented reality. This research employed the D&D (Design and Development) model. The subjects of this study were 6 expert validators in media and content, as well as 25 respondents. The data analysis techniques included Aiken’s analysis and percentage models. The study concluded that the validation of CHEMILARD media, developed across all assessment aspects, indicated that the product is feasible for trial implementation with a score of V=0.90 from media experts and V=0.91 from content experts. The respondents' test results showed an ideal media percentage of 90.3% and an overall media quality rating of 76.72, which is categorized as Very Good. This indicates that the augmented reality-based CHEMILARD media can significantly enhance the learning experience by making abstract chemical bonding concepts more tangible and easier to understand for students.

Abstract

Penelitian ini bertujuan untuk mendeskripsikan upaya meningkatkan kreativitas mahasiswa pada pembelajaran kimia menggunakan bahan ajar berbasis Project Based Learning (PjBL). Subjek pada penelitian ini adalah mahasiswa jurusan biologi semester 2 Institut Agama Islam Negeri (IAIN) Kerinci yang mengikuti perkuliahan kimia dasar. Penelitian dilakukan dengan desain One-Shot Case Study. Data hasil penelitian diperoleh dari analisis lembar observasi produk dengan skala berpikir kreatif (Creative Thinking Scale/CTS). Analisis data dengan teknik persentase dan diolah secara deskriptif. Hasil penelitian menunjukkan kreativitas mahasiswa dalam menghasilkan produk model-model bentuk molekul menggunakan bahan limbah lingkungan termasuk pada kategori sangat tinggi dengan nilai 80. Maka dapat disimpulkan bahwa penggunaan bahan ajar kimia berbasis Project Based Learning (PjBL) dapat meningkatkan kreativitas mahasiswa
