Abstract

Critical thinking skills, especially in science subjects, are insufficient because teachers only provide direct knowledge to students without giving students the opportunity to actively participate in learning. The aim of this research is to determine the influence of the Discovery Learning model towards the critical thinking skills of grade VII students at SMP Negeri 2 Kupang Tengah. This type of quantitative research uses a quasi experimental method. The research results show that the score of critical thinking skills of the students in experimental classes with an average posttest score of 80.46 higher than the pretest which is 50.04. Meanwhile, in the control class, the average pretest score was 45.21 and the average posttest score was 67.14. The results of the anacova test using the one-way anacova statistical analysis technique (one way-anacova) with the help of SPSS Version 23 obtained a probability value (sig) of 0.000 <from the set significant value of 0.05. Thus the null hypothesis (H 0 ) which states that there is no influence of the Discovery Learning model on students' critical thinking skills is rejected and the alternative hypothesis (Ha) which states that there is an influence of the Discovery Learning model on students' critical thinking skills is accepted. The conclusion of this research is that the Discovery Learning model influences the critical thinking skills of grade VII students at UPTD SMP Negeri 2 Kupang.

Abstract

Lantana camara L. memiliki warna mahkota bunga yang variasi. Meskipun berasal dari spesies yang sama, struktur sel epidermis dan stomata dari tumbuhan tersebut dapat berbeda. Perbedaan tersebut menambah kompleksitas dari mata kuliah anatomi tumbuhan sehingga mahasiswa pendidikan biologi Unwira mengalami kesulitan dalam memahami konsep dan ditambah dengan visualisasi materi yang kurang jelas dimana gambar yang digunakan selama perkuliahan berupa gambar ilustrasi yang berbeda dari setiap sumbernya. Selain itu, beberapa lensa mikroskop di laboratorium berjamur karena kurangnya perawatan sehingga mengaburkan pandangan dan mengurangi ketajaman gambar mengakibatkan informasi yang diperoleh menjadi tidak akurat. Tujuan dari penelitian ini yaitu untuk mengetahui struktur sel epidermis dan stomata daun Lantana camara L. dengan variasi warna dan untuk mengetahui kelayakan media e-atlas struktur sel epidermis dan stomata daun Lantana camara L. dengan variasi warna sebagai media pembelajaran pada mata kuliah anatomi tumbuhan. Jenis penelitian ini adalah penelitian dan pengembangan (Research & Development) dengan menggunakan model ADDIE, dengan metode stomatal printing. Data hasil penelitian dianalisis secara deskriptif. Hasil penelitian menunjukkan sel epidermis terdiri dari dua bentuk yakni bentuk lekukan memanjang (sampel berwarna kuning, orange, pink, dan pink-orange) dan bentuk yang tidak beraturan (sampel berwarna merah, putih, putih-kuning dan ungu). Jumlah sel tetangga yang dimiliki bervariasi dengan tipe stomata yaitu aktinositik (sampel yang berwarna kuning, orange, pink, dan pink-orange), anomositik (sampel merah, putih dan ungu) dan anisositik (sampel berwarna putih-kuning). Hasil validasi e-atlas memperoleh nilai rata-rata 81,25% dan dikategorikan sangat valid.

Abstract

Gunung Mutis National Park (TNGM), located in South Central Timor Regency, East Nusa Tenggara, contains a diverse range of highland herbaceous vegetation with the potential to be used as a learning resource. However, the lack of locally contextualized learning media poses challenges for Biology Education students in identifying herbaceous species during field studies. This research aims to develop an electronic atlas (e-atlas) based on herbaceous vegetation identification in TNGM as an interactive digital learning medium. This study employed the ADDIE model (Analysis, Design, Development, Implementation, Evaluation), involving 25 students and 3 expert validators. Data were collected through validation questionnaires, learning outcome tests, student questionnaires, and lecturer reflections, then analyzed using descriptive quantitative methods. The results indicate that the e-atlas is valid in terms of content and design, practical in application, visually engaging, and effective in enhancing students' understanding of herbaceous species. A total of 12 species from 8 families were documented and included in the e-atlas, complete with scientific information. This e-atlas has the potential to serve as a contextual learning medium based on local resources, promoting ecological literacy and improving botany education in conservation areas.
