<p class="0abstract">Science, Technology, Engineering, and Mathematics (STEM) is an interdisciplinary approach where academic concept coupled with a lesson or problems that exist in the real world so that students can apply science, technology, engineering, and mathematics in a context that makes the relationship between the school, community, work, and global companies that will emerge the ability to compete in the 21st-century integration of STEM in the classroom Form comprise of three, including integrated content, supporting an integrated content, or integrated context, STEM in its application aims to develop thinking, reasoning, teamwork, investigation, and 21st-century skills that can be used by students in all areas in their life, 21st-century skills to learn and innovate include critical thinking, creativity, communication, and collaboration known as the "Four Cs". This paper provides a comprehensive review of STEM as a learning approach to improve their skills, especially the skills of the 21st century "Four Cs" of the students. Skills "Four Cs" becomes one key to success is to be competitive in entering the era of information and knowledge.</p>

Abstrak: Tujuan penelitian ini untuk menganalisis pengaruh bahan ajar ekologi berbasis pendekatan STEM terhadap pembelajaran Abad-21. Metode penelitian ini adalah meta-analisis dengan menelaah sumber data yang berasal dari jurnal nasional atau internasional terbitan empat tahun terakhir (2016-2020). Hasil penelitian menunjukan bahwa studi meta-analisis berpengaruh pada bahan ajar ekologi berdasarkan pendekatan STEM berdasarkan tingkat pendidikan, jenis media yang digunakan, dan pendekatan STEM dalam pembelajaran ekologi. Temuan penelitian menunjukkan bahwa pengaruh bahan ajar ekologi berdasarkan pendekatan ilmiah memiliki harga rata-rata lebih tinggi di tingkat SMA dibandingkan dengan sekolah dasar dan menengah pertama. Harga ukuran efek rata-rata untuk tingkat pendidikan menengah atas, menengah pertama dan dasar adalah: 1,63; 1,56; dan 1,19 pada kategori tinggi. Sedangkan dari segi media pembelajaran akan lebih efektif jika diaplikasikan dalam modul, dibandingkan dengan media lain, rata-rata effect size modul, LKS/LKPD, dan bahan ajar masing-masing adalah: 2,05; 1,14; dan 0,62 pada kategori tinggi. Berdasarkan hasil belajar kognitif dan keterampilan siswa, pengaruh harga rata-rata terhadap effect size proses sains, hasil belajar, berpikir kritis, dan pemecahan masalah adalah 1,32; 1,61; 2.32; dan 1.83 dengan kategori tinggi maka diikuti kompetensi siswa dengan memberikan pengaruh pada kategori sedang yaitu: 0,61. Kata Kunci: Bahan Ajar, Pendekatan STEM, Ekologi Abstract: The purpose of this study was to analyze the effect of ecology teaching materials based on the STEM approach on 21st-century learning. This research method is a meta-analysis by examining data sources from national or international journals published in the last four years (2016-2020). The results showed that the meta-analysis study affected ecology teaching materials based on the STEM approach based on the level of education, the type of media used, and the STEM approach in ecological learning. The research findings showed that the effect size of ecological teaching materialbased on scientific approach has a higher average prize at senior secondary level compared to primary and junior secondary. The average effect size prices for senior secondary, junior secondary, and primary education levels were: 1.63; 1.56; and 1.19 in the high category. Meanwhile, in terms of learning media, it will be more effective if applied in modules, compared to other media, the average effect size of the module, student worksheet, and teaching materials respectively are: 2.05; 1.14; and 0.62 in the high category. Based on students' cognitive learning outcomes and skills, the effect of the average price on the effect size of the science process, learning outcomes, critical thinking, and problem-solving was 1.32; 1.61; 2.32; and 1.83 with the high category, followed by student competence by giving influence to the medium category, namely: 0.61. Keywords: Teaching Materials, STEM, ecology

The report is a part of developing integrative learning model (MPI) on the biology of animal development. The research objective was to determine the needs analysis of developing MPI on the biology of animal development at STAIN Batusangkar. The research use Plomp model. The data obtained will be analyzed by data reduction, data presentation and drawing conclusions. The result showed that philosophy of STAIN Batusangkar is an integration. Analysis of the characteristics of students showed that students of STAIN Batusangkar has a heterogeneous background of the aspects of capability. These results are based on the findings of the Academic Performance Index, schools and majors while undergoing studies in high school, the course precondition and the results of multiple intelegencie test. Developmental of biology material is characterized by the facts, concepts, principles and theories. In conclusion, the research is a part of activity that supports of developing MPI on the biology of animal development at STAIN Batusangkar.

The objective of this writing audit is to look at different pieces of writing about how project-based learning can help students think more creatively and critically. The survey on writing found that project-based learning can help students think more critically and creatively. For research, a narrative review design is used in a literature review. Over the course of five years, 19 scientific articles from national and international journals were used in this study. Reliable sources, the quality of the research process, the quality of delivering information, and the completeness of the information are some of the validation criteria for scientific articles. Simplifying, displaying, drawing conclusions, and verifying data are all part of the qualitative analysis model of Miles and Huberman's method for presenting tabular data. The writing survey uncovers that project-based learning strategies can upgrade understudies' basic and imaginative reasoning abilities in science acquiring. The syntax of the project-based learning method be able to assist students in optimizing their creative and critical mindsets by starting learning with essential questions, working together to plan, developing project completion schedules, timelines, and deadlines
