Adaptation of new habits in many aspects of life, including education, is required amid the COVID-19 outbreak. Many countries, including Indonesia, suddenly implement online learning as a realization of social distancing policies. This sudden change in the learning system has become a challenge for teachers. They must be able to integrate technology, pedagogy, and content knowledge to conduct online learning well. Therefore, this study investigates the readiness of biology teachers to face online learning based on their Technological Pedagogical Content Knowledge (TPACK). The purposive survey method was used by distributing questionnaires and conducting online interviews. The questionnaire consists of 30 statements about the TPACK readiness of biology teachers and ten questions about the online learning process during the COVID-19 outbreak. A total of 121 biology teachers in West Java, Indonesia, participated in this study. The findings indicate that biology teachers have sufficient TPACK skills in implementing online learning. However, their technological capabilities still need to be improved. The flexibility of place and time, availability of learning resources, and increased independence of teachers and students in using technology are the advantages of online biology learning during the COVID-19 outbreak. Meanwhile, the problems faced by teachers include technical connectivity and student honesty in taking exams in the implementation of online learning. The uncertainty of when the pandemic will end makes this study important to carry out for evaluation and potential improvement of online biology learning systems.

To compete in the 21st century, educators need to equip students with various skills called 21st-century skills. The purpose of this research is to identify and describe the perceptions of biology education lecturers and students regarding the authentic assessment of 21st-century skills. The method used in this research is an internet-based survey method. The research participants consisted of 7 lecturers and 80 students majoring in biology education. The instrument used is a result questionnaire consisting of 11 questions for lecturers and ten questions for students. The survey results show that lecturers and students know about the components and urgency of 21st-century skills. In addition, the assessment of these skills is also quite often done. However, there are still some obstacles in authentically assessing 21st-century skills.

Distance learning is a new learning model for students and teachers. Therefore, it requires a long time to adapt. This study aimed to describe students' attitudes towards anxiety. The research population was SMA NU Juntinyuat, and the research sample was 80 students of class ten. The data were collected using the questionnaires of student anxiety levels and student strategies. This study revealed that 44 students had a very anxious category while 36 students had an anxious type. The high school students' strategy to deal with anxiety showed that 50 students were in the anxiety category while 30 students were in the moderate coping category. These findings concluded that most students had a high anxiety level in learning biology. Meanwhile, students' strategies to solve anxiety were classified as a moderate-coping strategy in anxiety.

The COVID-19 outbreak has affected the world of education, including science learning. This paper aims to reveal one of the practices of learning science from home using a contextual approach to the topic of cultivating Ficus carica plants. The research method uses field studies, project analysis, and interviews. The results showed that: (1) Through project-based learning, students can reveal a lot of scientific information related to the topics discussed (2) Selection of issues that are close to the context of everyday life makes it easier for students to learn (3) Learning science from home can support to achieve the learning outcomes of lectures. This research concludes the importance of redesigning a more adaptive and flexible science learning curriculum during a pandemic outbreak.

This research aimed to describe students’ activities, the improvement differences of students' critical thinking skills, and explain students' responses toward the internalization of religious values using the Argument-Driven Inquiry model on reproductive system material at eleventh-grade students of MAN 1 Kuningan. The method used in this research was the quantitative method with the experimental pretest-posttest control group design. This research population was all eleventh-grade students of MAN 1 Kuningan, which consisted of eight classes, five science classes, and three social studies classes. The research sample was taken using a random sampling technique. This research sample was class XI IPA 1 as the experimental class (35 students) and XI IPA 3 as the control class (34 students). The data collection techniques employed were observation, tests, and questionnaires. The data was analyzed using SPSS v.25 software. The results obtained showed that the highest learning activity was at the data collection stage. There was an improvement in students’ critical thinking skills in the experimental class and the control class. The average N-Gain of the experimental class was 0.69, and the control class was 0.33. The sig statistical test results were 0.000 0.655, meaning that H0 was rejected and Ha was accepted. Thus, there was a significant improvement in students' critical thinking skills between the experimental and control classes.
