Changes in the learning process during the COVID-19 pandemic require quick adaptation from teachers and students to immediately achieve learning goals. However, it remains ineffective, resulting in a threat of learning loss. This condition can be overcome if students have confidence in their abilities or self-efficacy. It is important to do an analysis related to biology learning tasks taught by the teachers and students’ self-efficacy. This study aims to analyze biology learning tasks variation during the COVID-19 pandemic and its effect on students’ self-efficacy. This study used descriptive design with cross-sectional survey method. Samples were taken using the convenience sampling technique from five public schools. 446 students out of 465 total students and seven biology teachers participated in this study as respondents. The instruments used in this study were rubrics for quantifying learning tasks and self-efficacy questionnaires given to students after Biology Learning. The results show that all learning modes in Biology Learning during the COVID-19 pandemic have learning tasks that were more dominant in the low-level cognitive process. The dominant learning tasks include retrieval and comprehension, while learning tasks with a higher level of cognitive processing such as analysis, knowledge utilization, and metacognitive only cover a small part of the whole Biology learning process. There were no learning tasks that reached the highest level of cognitive process (self-system). The result of self-efficacy in all learning modes was high, but it was higher in learning modes that used hybrid learning. Biology learning tasks given by the teachers during the COVID-19 pandemic have an effect on students’ self-efficacy.

Currently the world is entering the era of the 5.0 industrial revolution, people are required to have various 21st century skills in order to compete in this new era. This is a challenge for Indonesia to develop its education. Practicum is one of the solutions for develop 21st century skills. But turns out that it still has weakness caused by inappropriate practical laboratory worksheet. This study aims to analyze and to reconstruct the practical laboratory worksheet of the tastebuds. The research method used is descriptive qualitative research with the ANCOR model. The sampling technique used was purposive sampling, the sample consisted of 10 practical laboratory worksheet of taste buds from the 2006 KTSP curriculum to the 2013 revised curriculum. The instruments include conceptual, practical, and the construction of knowledge aspect adapted from the Vee diagram. The findings show that the practical laboratory worksheet of the taste buds still has problems from various aspects. Practical laboratory worksheet of tastebuds reconstruction is needed so that students are able to construct their knowledge properly through practicum activities carried out and develop 21st century skills. Abstrak. Saat ini dunia memasuki era revolusi industri 5.0 sehingga masyarakat dituntut untuk memiliki keterampilan abad 21 agar mampu bersaing di era baru ini. Hal ini menjadi tantangan tersendiri bagi indonesia dalam mengembangkan pendidikan. Praktikum merupakan salah satu solusi untuk membentuk keterampilan-keterampilan abad 21 ternyata masih memiliki kekurangan karena DKL yang tidak sesuai. Tujuan penelitian adalah menganalisis dan rekonstruksi DKL materi indera pengecap. Metode penelitian yang digunakan deskriptif kualitatif dengan model ANCOR (Analisis, Uji Coba dan Rekosntruksi). Teknik sampling yang digunakan yaitu purposive sampling, sampel terdiri dari 10 DKL indera pengecap dari kurikulum KTSP 2006 hingga kurikulum 2013 revisi. Instrumen yang digunakan meliputi instrumen aspek konseptual, praktikal, dan konstruksi pengetahuan yang diadaptasi dari Diagram Vee. Hasil temuan menunjukkan DKL indera pengecap masih memiliki masalah dari berbagai aspek sehingga diperlukan rekonstruksi DKL indera pengecap agar siswa mampu mengkonstruksi pengetahuannya dengan baik melalui kegatan praktikum yang dilakukan dan mengembangkan keterampilan abad 21.
