This study aims to facilitate high school students’ communication skills and critical thinking ability with ICT-oriented problem-based online learning and assessment instrument with HOTS criteria. This research approach is pre-experimental, with the one group pre-test- post-test design. This study involved 36 students of XI MIPA 4 and biology teacher at a high school in Jepara, Indonesia. The number of samples determined using the purposive sampling technique. The data collected includes data on students’ critical thinking skills, students’ communication skills, implementation of the learning process, teacher and student response data regarding teaching materials, and the learning process. Data of critical thinking skills were analyzed using the n-gain test. Other data were analyzed descriptively qualitatively. The results showed that students achieved a critical thinking skill level with N-Gain 0.31 (medium category) and communication skills 83.00 (very good category). The average score of the implementation of the learning process is in a good category, meaning that all syntax is carried out well. Teachers and students consider that ICT-based teaching materials are quite practical to use. According to them, the learning process is in a good category (positive). Conclusion: students’ critical thinking skills and communication skills can be facilitated through online learning with ICT-oriented PBL approach teaching materials and ICT-oriented HOTS assessment instruments.

The research aimed to describe the validity, practicality, and effectiveness of Andro-Webcomic media based on problem-based learning as a learning media to improve students’ analytical thinking ability and scientific attitudes. The development design used was Research and Development (R&D) and used the ADDIE model, limited to the ADD (Analysis, Design, Development) stage. At the product development stage, small-scale trials are carried out, which this phrase was limited to 9 students of class XI MIPA at one of the high schools in Jepara. The instruments used were validation sheets, test sheets, observation sheets for students’ scientific attitudes, student and teacher questionnaire responses. The results of this study indicate that: (1) the validity of the Andro-Webcomic media is 95.58%; (2) effective in improving analytical thinking of 88.89% with an n-gain score of 67% and a scientific attitude of 87.19%; (3) practicality based on student responses of 98.39% and teacher responses of 97.36%; (4) media component that supports improving competencies is on the webcomic and investigation menu. Based on the research results, it can be concluded that the Andro-Webcomic media is valid, practical, and effective in improving students’ analytical thinking ability and scientific attitudes.

The objectives of this research are: (1) to examine the feasibility of competences and conservation-based textbook of Biology teaching management, (2) to test the effectiveness of the developed textbooks in the small and large-scale test. This study is an Educational Research and Development (R & D) following the stages of potential and problems analysis, data collection, product design, product validation, trial usage, product revision, and mass production. The results of the feasibility assessment of the product by the expert, the textbook have content the very feasible criteria (77,88), and media experts gave very feasible criteria (83,35). In the small-scale test, the students responded that the book had met the criteria of excellent legibility, on 14 indicators of product legibility with an average legibility value of 90,07. The textbook legibility is excellent since the sentence is understandable and communicative, has illustration adequacy, easy to use, relevant to the competences achievement, as well as there is the integration of conservation character values and TPACK description. The large-scale test showed that the application of the developed textbook was effective in maximizing the ability of prospective teachers’ PCK. It is found that competences and conservation-based Biology Teaching Management textbook are very feasible and powerful to maximize the PCK of prospective biology teachers.
