Abstract

This research aims to determine the differences in student learning outcomes in junior high school after receiving learning using the Problem-posing model and the direct learning model on Association material. The research method used in this research is a quasi-experiment with a Posttest Only Control Design by applying the Problem Posing learning model and the Direct learning model. In this research, the author used two sample classes, namely VIIA, using the Problem-solving learning model as the experimental class, and VIIB, using the direct learning model as the control class. The instrument used is four descriptive questions whose validity and reliability have been tested and scored. The results of data analysis show that the average student learning outcomes in the experimental class are 80.20 higher than the average student learning outcomes in the control class, namely 75.95; this indicates differences in student learning outcomes in the set metrics by applying the Problem-posing learning model. The results of data analysis using the Liliefors test and t-test show that the data obtained in this study is normally distributed, which means that applying the Problem-posing learning model influences students' ability to solve Association questions at St. Catholic Middle School.

Abstract

The objective of this study is to analyze the disparities in the mean learning achievements between students who utilize the SOLE learning model and those who employ the direct learning model for arithmetic sequence material at Tondano State Vocational School. The research employed a quasi-experimental design with a Posttest Only Control Group Design. The participants in this study consisted of students from class X OTKP 1, who were assigned to the experimental group, and students from class X OTKP 2, who were assigned to the control group. The data gathering method involved administering a technical learning outcomes test at the conclusion of the class (Posttest). The data analysis technique employed in this research utilizes tests on data that has undergone normality and homogeneity testing. The t test calculations yielded a t_count value of 2.736, which exceeded the critical t_table value of 1.685. Therefore, the null hypothesis (H_0) was rejected, and the alternative hypothesis (H_1) was accepted. Therefore, it can be inferred that there is a disparity in the mean learning results of students in the Self-Organized Learning Environment (SOLE) instructional approach and the traditional direct learning approach when it comes to arithmetic sequence material.

Abstract

This research aims to determine the difference in student learning outcomes regarding linear equations and inequality taught using the PBL model compared to student learning outcomes taught using the Direct Instruction model. This research is quasi-experimental. The samples in the research were class X-IPA as an experimental class with a total of 17 students. The instrument used in this research consisted of a learning outcomes test in the form of a written test in the form of an essay with material on linear equations and inequalities. The data collection technique is through observation and tests in the form of evaluation questions. The test is carried out twice. Namely, the pretest is carried out at the beginning of the research to determine students' achievement scores before treatment, and the posttest is carried out in both control and experimental groups after treatment. Based on hypothesis testing using independent test statistics (T-test), tcount = 3.596 and ttable = 1.694 at a significance level of ⍺ = 0.05. The research results show that the tcount value is more significant than ttable because (3.596 > 1.694) with a sig (2-tailed) value of 0.014 < 0.05 so it can be said that there is a significant difference in the learning outcomes of the experimental group using the PBL model and the control group using the Direct Instruction learning model which means that there is an influence of the application of the PBL learning model on the learning outcomes of class X students at SMA Negeri 2 Tondano.
