This descriptive study was conducted with the aim to determine the emergence of biological problems in class XE in terms of the scientific knowledge domain of scientific literacy covering aspects of content/content, procedural and epistemic. The sample of this study consisted of 295 questions contained in the 2009 edition of BSE Biology Class X book, determined by purposive sampling technique which included examples of questions and exercises. The instrument used in this study is a document analysis document about the domain of scientific knowledge of scientific literacy. The results of the problem analysis showed that the aspect of content had the highest percentage appearance of 85.42% (excellent category) compared to the procedural aspects of 9.83% (very poor) and epistemic aspects of 1.36% (less). Based on these results it can be concluded that the domains of scientific literacy scientific knowledge contained in the class X BSE book are not balanced evenly so that the distribution of the question needs to be rearranged.

<p>Penelitian ini bertujuan untuk mengetahui keterampilan kolaborasi siswa pada konsep sistem pernapasan manusia berdasarkan  <em>peer assessment</em> antar siswa. Metode penelitian yang digunakan dalam penelitian ini adalah deksriptif kualitatif. Populasi subyek penelitian ini adalah siswa kelas VIII C SMP Negeri 1 Sukaraja tahun ajaran 2019/2020, dengan sample acak sebanyak  11  siswa karena adanya pembatasan kegiatan pembelajaran akibat adanya pandemic covid-19. Teknik pengumpulan data pada penelitian ini terdiri dari observasi lapangan, pengisian angket dan penilaian  sesuai rubric oleh siswa serta dokumentasi selama penelitian. Hasil penelitian menunjukkan bahwa berdasarkan penilaian menggunakan peer assessment kemampuan kolaborasi siswa kelas VIII C SMP Negeri 1 Sukaraja sudah cukup, hal tersebut diketahui berdasarkan hasil presentase rata-rata ke lima indikator keterampilan kolaborasi sebesar 39,97% hasil rata-rata ini termasuk kedalam kategori cukup. Kategori yang cukup ini, menjelaskan bahwa siswa dalam berkolaborasi dengan teman sekelompoknya sudah cukup. Siswa memberikan respon positif terhadap pembelajaran pada konsep sistem pernapasan, siswa juga memberikan repon positif terhadap penilaian keterampilan kolaborasi menggunakan <em>peer assessment</em>, karena dapat mengetahui dan menilai keterampilan kolaborasi yang dimiliki</p><p> </p>

The use of tree thinking in learning biology is still rarely used. The purpose of this study was to identify the tree thinking emergence profile of senior high school students through the inquiry-based learning model. This research is using the experimental method. The approach used in this research is a qualitative approach. The population in this study was 36 students of class X in SMA Negeri Sukabumi. The samples were taken by using a purposive sampling technique. The data collection was performed using a written test in the form of LKS by using five tree thinking indicators. The results showed that the value of tree thinking students for the first indicator gained a percentage of 69% included in the good category, the second indicator obtained a percentage of 63% included in the good category, the third indicator received a percentage of 73% included in the good category, the fourth indicator obtained a percentage of 81% included in the very category good, and the fifth indicator gets a percentage of 52% included in the category enough. This result leads to the Student learning outcomes that are categorized as good because the students follow the learning by using models, strategies, and learning approaches that can improve their ability of tree thinking in Arthropoda subjects. This study suggests that the inquiry-based learning model can be used as an alternative in learning biology to improve tree thinking skills.
