Abstract

This study aims to determine the differences in student learning outcomes and the magnitude of the differences in student learning outcomes using the problem-based learning model and conventional methods on the human respiratory system material in grade XI of SMA Swasta Kartika I-4 Pematangsiantar in the 2021/2022 academic year. The population was 193 students consisting of 4 classes and the sample was taken using cluster random sampling to obtain 2 classes: the experimental class (XI mia 1) with 48 students and the control class (XI mia 3) with 48 students. The experimental class was treated using the problem-based learning model and the control class was treated using the conventional method. Data analysis was carried out by finding the average (X̅ ), standard deviation (S) and hypothesis testing (t-test) at a significance level of α = 0.05. From the results of the study, the average post-test score for the experimental class was 83.02 and the control class was 80.10 with a difference in learning outcomes of 2.29. From the results of the hypothesis testing (t-test), the calculated t (2.721 > t table (1.985) was obtained at a significance level of α = 0.05 and degrees of freedom (df) = 94, so Ho is rejected and Ha is accepted, meaning there is a difference in student learning outcomes using the problem-based learning model and the conventional method on the human respiratory system material in grade XI of SMA Swasta Kartika I-4 Pematangsiantar in the 2021/2022 academic year. It was concluded that there is a difference in student learning outcomes using the problem-based learning model and the conventional method on the human respiratory system material in grade XI of SMA Swasta Kartika I-4 Pematangsiantar in the 2021/2022 academic year.

Abstract

This study aims to determine differences in student learning outcomes using the Numbered Heads Together learning model. This research is an experimental study with a pre-test, post-test design. The population was 203 students, and the sample size was 80 students (Cluster Random Sampling). Class VII-2 served as the experimental class, and class VII-4 as the control class. Data analysis was conducted by calculating the average score and standard deviation, and hypotheses were tested using the t-statistic or t-test at a significance level of α = 0.05. The average pre-test score for the experimental class was 44.25, and the average post-test score for the experimental class was 78.37. The average pre-test score for the control class was 38.50, and the average post-test score for the control class was 65.25. This indicates an improvement in the topic of interdependence in ecosystems in class VII of MTs Negeri Tanah Jawa in the 2014/2015 academic year, with a score of 34.12. The results of the hypothesis test using the t-test obtained a calculated t (7.68) > t table (2.00), therefore H0 is rejected and Ha is accepted, meaning there is a difference in student learning outcomes using the Numbered Heads Together learning model on interdependence in ecosystems in grade VII MTs Negeri Tanah Jawa in the 2014/2015 academic year. It was concluded that there is a significant difference in learning outcomes using the Numbered Heads Together learning model on interdependence in ecosystems in grade VII MTs Negeri Tanah Jawa in the 2014/2015 academic year.

Abstract

The problem in this study is that online learning has decreased student motivation and interest, with only a few participating and being active in learning. The purpose of this study was to determine the influence of learning motivation and interest on the communication skills of statistical students (Virtual) at the Faculty of Teacher Training and Education, University of Indonesia (USI), Pematangsiantar, in the 2021/2022 academic year. This research is descriptive quantitative, with conclusions drawn through statistical analysis. The population and sample in this study were all fourth-semester students of the Biology Education study program at the Faculty of Teacher Training and Education, University of Indonesia (USI), Pematangsiantar, in the 2021/2022 academic year. Data were obtained through a questionnaire. The questionnaire was previously tested for data normality and linearity. The data analysis techniques used were simple linear regression analysis, t-test, R2 test, and F-test. The conclusion from the F-test was that F = 4.510, with a Sig. (2-tailed) value of 0.020, less than 0.05 (5%). This means that Ho is rejected and Ha is accepted. In conclusion, learning motivation significantly influences the statistical communication skills of (Virtual) students at the Faculty of Teacher Training and Education, University of Indonesia (USI) Pematangsiantar in the 2021/2022 academic year. The coefficient of determination obtained was 0.195. Based on the results of a simple linear regression test, Y = 58.300 + 0.119 X1 + 0.325 X2.

Abstract

This study aims to determine the differences in student learning outcomes using the Group Investigation and Numbered Heads Together learning models on environmental pollution in seventh-grade students at SMP Negeri 8 Pematangsiantar in the 2019/2020 academic year. The population in this study was all seventh-grade students at SMP Negeri 8 Pematangsiantar in the 2019/2020 academic year, consisting of eight classes with a total of 340 students. The sampling process was carried out using random class or cluster random sampling to obtain two classes: class VII-D as experimental class I using the Group Investigation learning model and class VII A as experimental class II using the Numbered Heads Together learning model. Data analysis was carried out by finding the average value, standard deviation, and hypotheses were tested using statistics or the t-test at a significance level of α = 0.05. The results obtained the average pre-test scores of experimental class I and experimental class II were 44.86 and 40.27, respectively. The post-test scores of experimental class I and experimental class II were 83.78 and 87.03 with a difference of 3.25. From the results of the hypothesis test using the t test, it was obtained that t count (2.517) > t table (1.66629), so Ha was accepted and H0 was rejected, meaning there was a difference in student learning outcomes using the Group Investigation and Numbered Head Together learning models on environmental pollution material for class VII of SMP Negeri 8 Pematangsiantar in the 2019/2020 academic year. It was concluded that there was a difference in student learning outcomes using the Group Investigation and Numbered Head Together learning models on environmental pollution material for class VII of SMP Negeri 8 Pematangsiantar in the 2019/2020 academic year.

Abstract

The Problem-Based Learning (PBL) model, or problem-based learning, is essential for science classes at the junior high school (SMP) level. This learning model can improve students' thinking skills, instill personal and social character values, and foster academic achievement through improved student learning outcomes. This study demonstrated a higher average post-test score (8.04) compared to the control class that did not implement the PBL model (6.87), a difference of 1.17 points.
