Pembelajaran Berbasis Masalah Biologi pada Aspek Kognitif: sebuah Meta-Analisis

Model pembelajaran problem-based learning (PBL) memiliki peranan dalam meningkatkan kualitas peserta didik. Penelitian ini bertujuan untuk menganalisis kembali tentang model pembelajaran PBL dalam pembelajaran Biologi terhadap aspek kognitif atau hasil belajar siswa. Penelitian ini menggunakan metode meta analisis dengan sampel sebanyak 15 jurnal nasional. Berdasarkan hasil analisis ternyata model pembelajaran PBL mampu meningkatkan hasil belajar biologi mulai dari terendah 15,03 % hingga tertinggi 61,76% dengan rata-rata 29,34%. Dengan memperoleh size efek yang kuat yaitu sebesar 0,97. Peningkatan yang paling signifikan pada penelitian model PBL yaitu sebesar 28,13 pada pembelajaran model PBL dengan didampingi dengan LKS dan dengan menerapkan pembelajaran berbasis pemecahan masalah pada materi tertentu. Hal tersebut meunjukkan bahwa penerapan model pembelajaran PBL dapat meningkatkan hasil belajar dalam pembelajaran biologi

Virtual Laboratory of Protists: Learning Media to Enhance Scientific Attitudes

A scientific attitude is important for students to have because scientific attitudes affect the learning process and outcomes. One way to improve scientific attitudes in students is using interactive and interesting learning media. Therefore, this study aims to see the effect of using virtual laboratory media on students's scientific attitudes. The method used in this study is a quantitative method with a quasi-experimental design. The instrument used in this study was a scientific attitude questionnaire in the form of a Likert scale. The data were analyzed descriptively and differently. The research samples used was 70 samples divided into 35 samples in the experimental class and 35 samples in the control class. Based on the results of the study, it was seen that there was an increase in the average value of scientific attitudes in each dimension of scientific attitudes after carrying out learning with virtual laboratory media. It was also known that based on ANCOVA test, the significance value was 0.000<0.05. So, it can be concluded that virtual laboratory media can improve the scientific attitude of students

Mosses at the Bodogol Natural Conservation Education CENTER: Species, Diversity Index, and Evenness Index

Mosses or Bryophytes are a group of cryptogamous plants or lower plants. Moss can be found in various places that have high humidity by attaching to various substrates, such as soil, rocks and tree bark. PPKA Bodogol is a potential area that protects endemic flora and fauna on the island of Java that has excellent humidity and air for moss growth and supports moss diversity. This study aims to determine the diversity of mosses and their relationship to environmental factors in the PPKA Bodogol. Data collection in this study was carried out at the PPKA Bodogol on 3 routes, namely Cikaweni, Rasamala and Kanopi. This research uses a purposive sampling method with a cover square technique. The results showed that the total number of moss species identified were 21 species. Then it was also known that the highest level of diversity was found on the Rasamala route with a diversity index of 3.03. In the Cikaweni route, was in moderate category, namely 1,967. The lowest diversity index, however, was in the canopy path with a medium category, namely 1.216. Environmental factors such as humidity, temperature, light intensity, and altitude also had an influence on the level of moss diversity of the three routes
