Abstract

Mahasiswa menganggap materi asam basa senyawa organik sulit karena konsep yang abstrak dan memuat aspek multi representasi yaitu simbolik, mikroskopis dan makroskopis. Oleh sebab itu, suatu bahan ajar berupa e-modul multi representasi sangat diperlukan agar dapat membantu mahasiswa memahami materi tersebut. Tujuan penelitian ini untuk menentukan kelayakan, mengukur respon mahasiswa dan respon dosen terhadap e-modul multi representasi berbasis flip pdf corporate edition pada materi sifat asam basa senyawa organik. Jenis penelitian adalah Research and Development. Model pengembangan analysis, design, development, implementation and evaluation (ADDIE) yang digunakan dalam penelitian ini dibatasi hingga tahap pengembangan (development). Teknik pengumpulan data adalah teknik kuesioner. Instrumen penelitian yang digunakan adalah lembar penilaian kelayakan dan angket respon. Subjek penelitian adalah mahasiswa program studi Pendidikan Kimia FKIP Universitas Tanjungpura angkatan 2019 sebanyak 9 orang untuk uji coba kelompok kecil dan 30 orang untuk uji kelompok besar, serta dua orang dosen pengampu mata kuliah kimia organik. Hasil penelitian menunjukkan bahwa e-modul sangat layak dan respon yang sangat baik dari mahasiswa dan dosen. Kelayakan produk berdasarkan penilaian dan tanggapan dari para ahli. Respon mahasiswa dan dosen terhadap e-modul diukur menggunakan angket respon. Hasil penilaian kelayakan sebesar 93.3% pada aspek materi, 96.7% pada aspek bahasa dan 97.9% pada aspek kegrafikan. Persentase respon mahasiswa sebesar 88.5% pada uji kelompok kecil dan 89.8% pada uji kelompok besar, serta 86.1% pada uji respon dosen. Berdasarkan hasil yang diperoleh dapat disimpulkan bahwa e-modul multi representasi berbasis flip pdf corporate edition pada materi sifat asam basa senyawa organik dapat digunakan sebagai sumber belajar tambahan.

Abstract

Material in chemistry learning will be easier to understand if students are able to represent it at three levels of representation, namely macroscopic, sub-microscopic and symbolic. This research aims to describe students' abilities in using various representations in class XI MIPA 1 hydrocarbon material at SMA Negeri 1 Sungai Kunyit. Students' thinking processes require various representations and various ways or steps to solve problems. The type of research used is quantitative descriptive research. The research instruments used included 9 two tier multiple choice objective test questions and an interview guide. This research involved 20 students of class XI MIPA 1 SMA Negeri 1 Sungai Kunyit. The research results show that overall, the average multi-representation ability of students is 29% in the poor category. At the macroscopic representation level, the average percentage obtained is 20% which can be classified as very poor. At the sub-microscopic level of representation, the average is 35% which is included in the poor category. Finally, at the level of symbolic representation the average percentage is 31% which is also included in the poor category.

Abstract

This research aims to produce a product in the form of a booklet assisted by an animated video by utilizing QR codes on constitutional isomers sub-material to increase student understanding and reduce misconceptions on constitutional isomers. This research method is research and development (R&D) with a 4D development model consisting of the Define, Design, Develop and Disseminate stages. However, this research only reached the Develop stage. The validation data was analyzed using Content Validity Ratio (CVR) and Content Validity Index (CVI), while the student response questionnaire to the product was measured using a Likert scale. The results of product validation from every aspect, both in booklets and animated videos, obtained a CVI value of 0.99 and were declared valid and suitable for use as learning media. Students also gave good responses, which was shown in the initial response test with a percentage of 85% in the good category and in the main response test with a percentage of 84% in the good category.

Abstract

The ability of prospective teacher students to master chemistry material will influence the achievement of learning objectives. Alkenes are an important sub material in organic chemistry courses because alkenes are often used as basic ingredients in chemical reactions. This research aims to analyze Untan chemistry education students' understanding of alkene sub materials. The research method used is quantitative descriptive. The research sample consisted of 50 students. The instrument used was Three-Tier Multiple Choice with a total of 10 questions and a semi-structured interview. Before using the instrument, a validity and reliability test was carried out first. The analysis results of students who understand the concept well are only 28.06%, and 6.06% of students understand but are not sure, while the percentage of students who do not understand the concept is 40.21%, and 29.95% of students experience misconceptions.
