Abstract

This study aims to increase the activity and learning achievement of class XI MIA I SMA Negeri 5 Balikpapan in the academic year 2021/2022. The subjects of this study were students of class XI MIA I SMA Negeri 5 Balikpapan for the 2021/2022 academic year. This research is a classroom action research (CAR) using two cycles. The instruments used in this study were observation sheets of student learning activities and student achievement test sheets. The results showed that the results of student learning activities in the first cycle reached 72.14% in the good category, while in the second cycle it reached 86.43% in the very good category. The classical completeness of student achievement in the first cycle is 50%, while the classical completeness in the second cycle is 60%. Thus, it can be concluded that the application of the Student Team Achievement Division (STAD) can increase student activity and achievement in class XI MIA I SMA Negeri 5 Balikpapan in the 2021/2022 academic year.

Abstract

This research is motivated by the condition of the implementation of learning which mostly still uses lecture-based or conventional learning models, where the learning process carried out is more centered on the educator himself, while students only receive the learning materials given, this affects the cognitive learning outcomes of students. Therefore, educators are required to use a variety of learning models in order to optimize the learning process. The purpose of this study was to determine the effect of the Project-Based Learning Model on the cognitive learning outcomes of students at SMAN 10 Samarinda. This research is a quantitative study with the Quasi Experiment method. The number of samples in this study was 48 respondents consisting of 24 respondents for class X1 and 24 respondents from class X2. The sampling technique in this study used the Purposive Sampling technique. This study uses primary data whose data collection is by distributing test sheets. The results of the study show that the significant value obtained is 0.000 which is far below the significance level (0.05) which indicates that H0 can be rejected, because there is strong evidence that the Project-Based Learning Model has a significant effect on students' cognitive learning outcomes.

Abstract

Biology learning aims to develop critical thinking abilities and problem-solving skills, so that students can understand biological concepts, solve problems, and communicate solutions systematically. The aim of this research is to increase students' understanding of biological concepts through the application of contextual teaching and learning models. This type of research uses classroom action research which is carried out in two cycles. The subjects of this research were students in class XI MIA I SMA Negeri 5 Balikpapan, with a total of 32 students, consisting of 3 female students and 29 male students. The research instrument used was a test sheet. The data analysis technique used is quantitative. The results of the research showed that the test results evaluating students' understanding of biological concepts in cycle I had a classical completeness percentage of 45.14%. In cycle II, the test results evaluated students' understanding of biological concepts with a classical completeness percentage of 99%. There was an increase in the percentage of classical completeness by 53.86%. So it can be concluded that the contextual teaching and learning model has succeeded in increasing the understanding of biological concepts in class XI MIA I SMA Negeri 5 Balikpapan students.
