Development of STEM-Based Biology E-Module to Improve Student Learning Outcomes

One of the factors for improving the quality of education in schools is teaching materials. Based on the results of observations at SMAN 1 Sitiung students have not used e-modules but use electronic teaching materials in the form of pdf files downloaded from the internet and only in the form of writing and a few pictures. Based on the questionnaire results, it is known that students have difficulty understanding the concept of the respiratory system material. This causes low student learning outcomes as evidenced by the daily test scores that are still below the minimum completeness criteria. So, it takes teaching materials that can help in visualizing the subject matter. This type of research is Plomp model development research which consists of three stages: the initial investigation stage, the development or prototyping stage, and the assessment stage. The research subjects were class XI students at SMAN 1 Sitiung for the 2022-2023 academic year. Validation results by the validator on e-module-based Science Technology Engineering and Mathematics (STEM) show an average grade 88.05% (very valid). Practical results by Biology teachers showed an average score of 87.50% (very practical) and 88.28% students (very practical). Effectiveness test data has effectiveness with very effective criteria in terms of cognitive competency assessment with an average of 83.59, affective with an average of 84.24, and psychomotor with an average of 81.08Faktor peningkatan mutu pendidikan di sekolah salah satunya yaitu bahan ajar. Berdasarkan hasil observasi di SMAN 1 Sitiung bahwa peserta didik belum menggunakan e-module tetapi menggunakan bahan ajar elektronik dalam bentuk file pdf yang di download dari internet serta hanya berupa tulisan dan sedikit gambar. Berdasarkan hasil angket, diketahui peserta didik mengalami kesulitan untuk memahami konsep materi sistem pernapasan. Hal ini menyebabkan rendahnya hasil belajar peserta didik yang dibuktikan dengan nilai ulangan harian masih di bawah KKM. Sehingga dibutuhkan bahan ajar yang dapat membantu dalam memvisualisasikan materi pelajaran. Jenis penelitian ini adalah penelitian pengembangan model Plomp yang terdiri dari tiga tahap yaitu tahap investigasi awal, tahap pengembangan atau pembuatan prototipe, dan tahap penilaian. Subjek penelitian adalah peserta didik kelas XI SMAN 1 Sitiung Tahun Pelajaran 2022-2023. Hasil validasi oleh validator terhadap e-module berbasis Science Technology Engineering And Mathematics (STEM) menunjukkan nilai rata-rata 88,05% (sangat valid). Hasil Praktikalitas oleh guru Biologi menunjukkan nilai rata-rata 87,5% (sangat praktis) dan peserta didik 88,28% (sangat praktis). Data uji efektivitas memiliki efektivitas dengan kriteria sangat efektif ditinjau dari penilaian kompetensi kognitif dengan rata-rata 83,59, afektif dengan rata-rata 84,24, psikomotor dengan rata-rata 81,08. &nbsp
