Abstract

This study aims to determine the application of the CTL (Contextual Teacher And Learning) learning model assisted by visual media to student learning outcomes in plant tissue material for class XI at  Senior hight School  1 Sidamanik. The problem in this study is the low learning outcomes of students which are known from the results of interviews with one of the teachers in the field of biology studies at Senior hight School 1 Sidamanik. Therefore, the CTL (Contextual Teacher And Learning) learning model with the aid of visual media is applied to plant tissue material. The method in this research is quantitative, with the type of research Pre-Experimental Design and research design One Group Pret-test-Post-test design. The study population was all students of class XI semester 1 at Senior hight School  1 Sidamanik for the academic year 2022/2023, the sample of this study was class XI IPA II, which consisted of 33 students. This study uses a test instrument to measure learning outcomes before and after the study. The test used consists of 30 questions. After completing the validity test, there are 20 valid questions and 10 invalid questions. The results of the research show that the learning outcomes of students have increased. It can be seen before and after the treatment, the average value of the pre-test results an average value of 43.9. After treatment with the CTL learning model (contextualized teaching and learning), post-test scores increased by an average of 77.00. It is then analyzed using the N-Profit formula to obtain a percentage of 58.53, which falls into the "very efficient" category. Kata kunci: Hasil belajar,Model pembelajaran CTL (Contextual Teacher And Learning), Media Visual

Abstract

The purpose of this study is to determine: The effect of Course Review Horay Learning model on the learning outcomes of biology students in class XI material of the body's defense system at Senior hight school 1 Sidamanik in the academic year 2021/2022. This type of research is a quantitative research in which the research population includes all students of class XI SMA Negeri 1 Sidamanik in the academic year 2021/2022, so up to 175 students. The samples of this study were 70 students of classes XI IPA 2 and XI IPA 3. The instrument used in this study was a multiple choice test with a quasi-experimental research type and a non-equivalent control group design. The independent variable is Horay Course Overview and the dependent variable is learning outcomes. The results of the students' data were compared with the norms, and the study result data were analyzed using the N-Gain test and Independent Sample T-Test. The results showed that the "Course review" method had a great impact on the results of the education of the students of the 11th grade of the 6th grade of Sidamanik in the subject of biology, the material of the body's defense system. The learning outcomes of the students in the experimental class achieved good characteristics, and the control class achieved only sufficient characteristics. The experimental group mean test was 83.14 and the control class mean post test was 76.57. It shows that the N-profit index of the experimental group is 0.706 (high), while the N-profit index of the control class is 0.452 (average). The results of the independent sample test showed the value of tcount(4.226) > ttable(1.995), which means that the Course Review Method can improve the results of students' learning about the immune system and the impact value. Sig. (2-tailed) < 0.05 is 0.000. The conclusion is that Horai's course review study method affects students' learning outcomes in biology. Kata kunci: Course Review Horay, Hasil Belajar
