<![CDATA[Based on the results of observations at SMAN 15 Semarang students still have difficulty working on the questions requires analysis, evaluation, and a high degree of difficulty. In addition, learning has not stimulated students to improve critical thinking skills. Learning that is applied is still more dominant in the aspect of knowledge, it does not require students to be active and train thinking to find independent concepts. This study aims to analyze the effect of PBL learning by analyzing the case study material of the respiration system on students' critical thinking skills. This research was conducted at SMA N 15 Semarang with the research design Nonequivalent Control Group Design. The research steps included preliminary observation including potential and problem analysis, determining the subject as a sample, namely class XI MIPA 6 as the control class and XI MIPA 7 as the experimental class, making learning tools, compiling research instruments, conducting test questions in class XII MIPA 3, question trial analysis, research implementation, research data analysis, preparation of research results discussion. The data analysis was carried out by the prerequisite test with the normality and homogeneity test. Normality test with SPSS ver. 21 it is known that the Kolmogorov Smirnov significance criteria of 0.200> 0.05 and 0.074> 0.05 can indicate that the experimental and control classes are normally distributed. The homogeneity test shows that the Leven's significance criteria 0.163> 0.05 in both samples have the same variance. After fulfilling the prerequisite test, the two mean difference test was carried out with the test known that the significance value was 0.000 <0.05 because of the significant difference between the two samples. Then performed the N-Gain test to measure the increase in critical thinking skills. The results of the N-Gain of the experimental class in the high category were 52% and the medium category was 48%, while in the control class the moderate category was 54% and 46% low.

<![CDATA[Biology is a subject that involves the scientific process in its teaching and learning activity so that it requires a learning model which can apply that scientific process, one of which is guided inquiry. The learning subject of virus is abstract, cannot be seen directly in everyday life and is microscopic in nature within which requires visual presence, not only verbal explanation so that students can fulfil their basic competence, namely analyzing (C4) which is included in the category of high-level thinking. In the learning model implemented at SMA N 1 Lasem, the teacher has not yet developed students’ critical thinking skills. One of the learning models that can be applied to improve critical thinking skills is guided inquiry based on multiple representations. The aim of this research is to determine the effectiveness of the implementation of guided inquiry in the learning subject of virus based on multiple representations toward students’ critical thinking skills. This research is an experimental research with a pre-test post-test control group design. The sample was class of X MIPA 3 as the experimental class and class of X MIPA 5 as the control class. The researchers used purposive sampling technique. The data collection methods were tests, observations, and questionnaires. The result showed that the average post-test mark of the experimental class was higher than that of the control class; that is 80.1 with classical completeness up to 92% and N-gain of 0.46 categorized as medium in the experimental class, while in the control class, the average post-test mark is 72.5 with a classical completeness of 78% and N-gain of 0.24 categorized as low. These results were strengthened by a questionnaire on students responses, teacher responses and observations of the learning process which gave a positive response with ≥ 75% categorized as good to the guided inquiry learning model based on multiple representations in the learning subject of virus. Based on the results of the research, it can be concluded that the implementation of guided inquiry based on multiple representations in the learning subject of virus is effective in improving students’ critical thinking skills.]]>

<![CDATA[Learning practices in the midst of the Covid-19 pandemic do not allow face-to-face meetings at schools. In order to optimize the learning process, it is necessary to have appropriate learning supports and allow students to learn from home. The nervous system is a material that is difficult for students to understand because of its complex and abstract. Augmented Reality (AR)-based learning media can involve students in the learning process and help improve visualization skills. The purpose of this study was to analyze the feasibility of Augmented Reality Nervous System (ARSaf) learning media to improve students' understanding. This study uses a 3-D model (define, design, and develop) which is modified from the 4-D model by Thiagarajan, Semmel, and Sammel (1974) covering the define, design, develop, and disseminate stages. ARSaf learning media validation was carried out to validate the media and material aspects. Validation was carried out by media experts, materials experts, and biology teachers using a modified questionnaire from the 2014 BSNP and the book "Visual Usability Principles and Practices for Designing Digital Applications" (Schlatter & Levinson, 2013). Limited field trials were conducted at SMAN 2 Ungaran online. The research subjects were 18 students with different categories of cognitive abilities, namely upper level, intermediate level, and lower level students from three different classes. The results of the validation of material experts are 86.76%, media experts are 95.19%, validation of material by biology teachers are 94.12%, and validation of media by biology teachers 91.35%. After the validation stage, the product revision stage is carried out. The value of the results of the evaluation of student learning meets the KKM with the highest score of 100 and the lowest score of 75. The results of student responses are 82.85% and teacher responses are 89.13%. The results showed that the ARSaf learning media that was developed was feasible to be used to improve students' understanding.]]>
