Abstract

This study aims to determine whether pop-up book media assisted by the application of the project-based earning model can be said to be feasible as a learning medium and to determine the increase in the creative dimension of students. This research uses ADDIE development research design and classroom action research (PTK). The results of this study showed a percentage of 86% for media experts who could be categorized as very feasible, 92% for material experts who could be categorized as very feasible, 91% for student responses who were included in the very feasible category. The results of this study also show that there is an increase in the creative dimension of students which can be seen from the acquisition of data in cycle I and cycle II. In cycle I there were 8 students who had criteria to develop according to expectations with a percentage of 32%, then in cycle II as many as 24 students who had criteria to develop very well with a percentage of 96%. So it can be concluded that the media developed in the form of pop-up book media assisted by the project based learning model can be said to be feasible as a learning medium and can increase the creative dimension of students.

Abstract

This study is a classroom action research study aimed to describe the improvement of students' critical thinking skills in Biology through the implementation of the Think Talk Write learning model. The subjects were 40 students of class X MIPA-1 MAS Al Washliyah Serbelawan. The study was conducted through four stages: planning, implementation, observation, and reflection. This classroom action research study used a collaborative model that prioritizes cooperation between teachers and researchers. Data collection methods included observation and a critical thinking test. The instruments used were teacher and student observation sheets and a 20-item critical thinking test. Before being used as a data collection tool, the instruments were pre-tested to determine validity, reliability, and normality. Based on the results, the average improvement in students' critical thinking skills was 50% in cycle I, then increased to 92.5% in cycle II. From these results, it can be concluded that the implementation of the Think Talk Write learning model can improve students' critical thinking skills in class X MIPA-1 MAS Al Washliyah Serbelawan.

Abstract

This study aims to determine the effect of audiovisual media use on science learning outcomes in the subject of Excretion for eighth-grade students at SMP Negeri 13 Pematangsiantar. The population in this study were 60 eighth-grade students of SMP Negeri 13 Pematangsiantar in the 2021/2022 academic year. The research sample was selected using cluster random sampling: class VIII A (Experimental Class) using audiovisual media and class VIII B (Control Class) using conventional methods. The instrument used in this study was a multiple-choice test consisting of 20 questions. Furthermore, the data obtained were analyzed to find the mean, median, mode, standard deviation, normality test, reliability, validity, and t-test. The data obtained were then analyzed using a t-test using SPSS 21. The results of this study indicate a significant effect between the use of audio-visual media on learning outcomes, with a probability value of 0.000 <α = 0.05, with a t-count of 7.688 > t-table of 1.699. Therefore, H_a is accepted and H_0 is rejected, meaning that the use of audio-visual media has an effect on the science learning outcomes of eighth-grade students at SMP Negeri 13 Pematangsiantar in the 2021/2022 academic year.

Abstract

This study aimed to determine the effect of the problem-based learning (PBL) model on students' science learning outcomes on environmental pollution in grade VII of SMP Negeri 2 Dolok Panribuan in the even semester of the 2019/2020 academic year. The study used a quasiexperimental method with a posttest-only control design. The sample of this study was 66 grade VII students of SMP Negeri 2 Dolok Panribuan. The research instrument was a test divided into a pre-test (given before learning) and a post-test (given after learning with different treatments). The pre-test and post-test were conducted in the form of 20 multiple-choice questions. Each correct answer was given a score of 5 and an incorrect answer was given a score of 0. Thus, the score range was 0-100. The prerequisite techniques for data analysis were normality and homogeneity tests. Furthermore, the data were analyzed by calculating the average score (mean) and the magnitude of the standard deviation (S). Based on the research results, the total post-test score of the experimental class was 3155 with an average score of 95.60, and the total post-test score of the control class was 3050 with an average learning outcome score of 92.61 with a difference of 3.19. Based on the results of the hypothesis testing, in the t-test, the calculated t = 2.13 was obtained and at the significance level of ɑ = 0.05 and df = 32, the obtained t table = 2.03. So, t count > t table, then H0 is rejected and Ha is accepted, meaning there is an effect of the use of problem-based learning models on students' science learning outcomes on environmental pollution material for class VII of SMP Negeri 2 Dolok Panribuan in the 2019/2020 academic year. Based on the results of the correlation test, the problem-based learning model has an effect on students' science learning outcomes on environmental pollution material for class VII of SMP Negeri 2 Dolok Panribuan in the 2019/2020 academic year.
