<![CDATA[SMA Negeri 10 Semarang is a school in Semarang which applies Budidaya Lele (BDL) subject. This subject is in accordance with the learning reference in the 2013 Curriculum. One of the goals to be achieved in the 2013 Curriculum is improving students’ critical thinking abilities. However, the facts show that students’ critical thinking abilities in SMA Negeri 10 Semarang are still low. One factor causing the low level of critical thinking abilities is conventional learning model implementation and teacher-centered. One of the learning models that can help improve students’ critical thinking abilities is Guided Discovery Learning (GDL). This study aims to investigate the effect of GDL model on students’ critical thinking abilities of grade 11 science in BDL subject. The sampling technique was purposive sampling. The research object was students in 11 science 4 class as the experimental class applying GDL model and students in 11 science 3 class as the control class applying conventional learning model. The aspects of critical thinking abilities measured were ability to provide simple explanation, ability to develop basic skills by using the indicators of considering trusted sources, ability to draw conclusion, ability to provide further explanation, and ability to manage strategies and tactics. The data was collected through tests and questionnaires. The data of test results was analyzed by using T test using SPSS and N-Gain test in Microsoft Excel 2010, while the questionnaire data was descriptively analyzed. The data analysis result of T test shows a mean difference in the experiment class and control class indicated by sig. value (2-tailed) as much as 0.000. The result of N-gain test, the experimental class has 0.43 value with medium criteria and the control class has 0.24 value with low criteria. The results of the two tests show that GDL model implementation affects students’ critical thinking abilities in the experimental class in BDL lesson. Students in the experimental class applying GDL model have better critical thinking abilities compared to students in the control class which does not apply GDL model.]]>

<![CDATA[Student learning outcomes at Pemalang 2 High School are still low students are less actively involved in learning activities. This is because Biology learning applied by the teacher still uses the lecture model. In this learning model, the teacher has not developed science process skills (SPS). One learning model that can be applied to improve SPS and student learning outcomes is problem-based learning. The purposes of this study are to determine the differences in student learning outcomes in virus material, to determine the effect of the application of problem-based learning models to student SPS, and to test the effectiveness of problem-based learning. This research is a quasi-experiment with nonequivalent control group design. The research sample is determined by purposive sampling. Data collection is done by test, observation, and questionnaire methods. The results show that the percentage of students classical completeness in the experimental class reach 88% while the control class is 72%. The results of the ttest show tcount = 2.80> ttable = 1.99 so that there is a difference in learning outcomes increase in the experimental class. The N-gain test shows the N-gain value of the experimental class 0.62 and the control class 0.52. The improvement of students' understanding in the experimental class was better than the control class. Student's SPS increase is directly proportional to student learning outcomes. Based on the results of the study, it is concluded that there are significant differences from the learning outcomes of the control class and experimental class. The application of problem-based learning has a positive influence on student SPS and problem-based learning is effective in student learning outcomes.]]>
