Abstract

The problem in this research is the low social studies learning outcomes of students in the learning process. This research aims to determine the influence of learning motivation and learning facilities on student learning outcomes in social studies subjects for class VIII at Taman Siswa Pematangsiantar Adult Park (SMP).The variables in this research are learning motivation and learning facilities as independent variables and learning outcomes as the dependent variable. This type of research is quantitative research, with the research population being Class VIII students at Taman Siswa Pematangsiantar Adult School (SMP) consisting of 76 students using nonprobability sampling (saturated sample). The data collection technique uses instruments: (1) Learning Motivation questionnaire, (2) Learning Facilities questionnaire and, (3) Learning Results in the form of mid-semester exam scores.The results of this research show that: (1) There is a negative and significant influence between learning motivation variables on learning outcomes. This result can be seen in the t test where the tcount value of learning motivation shows tcount < ttable, namely -3.866 < 1.669. (2) There is a positive and significant influence between the learning facility variables on learning outcomes, this result is in the t test where the tcount value of learning facilities shows tcount > ttable, namely 3,622 > 1,699.(3) There is a significant influence of learning motivation and learning facilities on learning outcomes. This result can be seen in the F test where the F value is 13,668 > F table 3.12. So based on the calculation results above, it can be concluded that the research results reject the null hypothesis (H03) and accept the alternative hypothesis (Ha3). Thus, together learning motivation and learning facilities influence the learning outcomes of class VIII students in social studies subjects at Taman Siswa Pematangsiantar Adult Park (SMP) can be accepted.The R Square coefficient of determination test was found to be 0.272, equal to 27.2% of the learning motivation variables and learning facilities influencing student learning outcomes at Taman Siswa Pematangsiantar Adult Park (SMP) and the remaining 73% was the influence of other variables not examined in this research. Multiple regression = Y =78,548 – 0.230 x1 + 0.265 X2 + 791,538

Abstract

This research focuses on the use of the NHT learning model on the learning outcomes of grade X students in Economics subjects. The objectives to be achieved in this study are to determine the improvement of learning outcomes in students by applying the NHT cooperative learning model and comparing the effect of learning outcomes using the NHT cooperative learning model with the learning outcomes of students using lecture learning.The research method used was a quasi-experimental design method using descriptive statistics. The data collection method was carried out using one experimental group and one control group, the experimental group was given a pre-test and treatment with learning using the NHT model, after which a post-test was given. Then with a different class, the control group was given a pre-test and treatment with learning using the lecture method, after which a post-test was given. The participants in this study were two classes, including the experimental class in class X1 and the control class in class X3.The results showed that there was an effect of student learning outcomes, on the learning model used in the teaching and learning process can be seen in the learning outcomes of students who used the NHT model, had a completeness value of 75.5 and in the control class that used the lecture method of 60.4.
