The purpose of this study was to determine differences in students' cognitive learning outcomes (CLO) using demonstration and experimental learning methods. The Clo differences are in students who have high critical thinking skills (HCTS) and low critical thinking skills (LCTS), and whether there is or not the interaction between learning methods and critical thinking towards students CLO. Hopefully, this research could strengthen existing theories and inform other teacher colleagues by using demonstration and experimentation methods in other subjects to improve the quality of a school. The study design used a 2 x 2 factorial design. The study population was students of X science class in one of the state high schools in Central Lombok, Indonesia, which amounted to 18 schools. The study sample amounted to 2 schools. In order to select the research sample, we used purposive random sampling. CLO and critical thinking skills were measured by using essay tests.esting on the validity and reliability of CLO tests and critical thinking skill showed valid and reliable results. Data were analyzed using ANCOVA with pre-test scores as covariates. The results showed that there were significant differences in CLO between students learning to use the demonstration and experimental learning method. There was a significant difference in CLO between students who have HCTS and LCTS, and there was no interaction between learning methods and critical thinking on student’s CLO. Experimental method learning is more optimal to improving student CLO when When it is applied to HCTS students rather than LCTS students on Archaebacteria and Eubacteria.

The broad scope of biology and the many sources of biology reading requires eleven grade students to think critically about sorting out information to develop and support students' critical thinking skills. CirGi is an integration of the cooperative integrated reading and composition (CIRC) learning model and guided inquiry (GI) that emphasizes reading and writing activities, accompanied by guidance from the teacher. This study aimed to analyze the influence of CirGi's learning model on students' critical thinking skills. This research uses a quasi-experiment method with pre-post control group design. The sampling technique used purposive sampling, namely 104 high school students. Data collection was carried out using instruments of critical thinking skills in the form of essays, questionnaire responses of students to learning, and observation sheets of syntax implementation. The data analysis technique used was one-way ANCOVA. After controlling for the pretest scores, the CirGi learning model's influence on students' critical thinking skills was influenced. This learning model was appropriate for learning biology, so it can regrow the activities of reading science books that impact students' critical thinking skills.

The purpose of this study was to analyze gender-based biological concepts understanding at secondary school students of bilingual programs. 6 (sixth) problems, according to Bloom's taxonomy categorization, were designed consisted of: understanding, applying, analyzing, evaluating, and creating. The topics included cell, classification of the organism, ecology, plant anatomy and physiology, and human anatomy and physiology. Samples were 47 students from grade nine (secondary school) from one of bilingual secondary schools in Jakarta, Indonesia. Data obtained were analyzed quantitatively and qualitatively. The analysis showed that the average value of the concept comprehension test was 55.07, which was below the Minimum Criteria of Completeness score of 73. The average value of male students was 57.29, and the average value of female students was 52.85. There was no significant difference between the learning outcomes of male and female students. Some male students have higher achievements because they have more engagement in science than others. Students' low ability to understand the biology concept makes them unable to perform their competency at the stages of applying, analyzing, evaluating, and creating. Overall, data showed that the average level of understanding of biological concepts for secondary school of bilingual programs still tends to be low and needs to be continuously improved in the learning process. Hopefully, further studies can be conducted to develop the most appropriate learning method to improve biological concepts.
