Abstract

This study aims to determine whether there is an effect of the scientific approach assisted by focusky on the learning motivation and mathematical reasoning abilities of junior high school students on quadrilateral material. This research is included in the quasi-experimental category. The population in this study were all seventh grade students of SMP Negeri 1 Lubuk Pakam T.A 2021/2022. In this study, two classes were selected as samples, namely class VII-A was selected as the experimental class and class VII-U was selected as the control class through purposive sampling technique, each class consisted of 30 people. The experimental class was given teaching by learning using a scientific approach with help of focusky, while the control class was given teaching by learning using an expository approach. The research instrument used was a learning motivation questionnaire and a test in the form of a description of mathematical reasoning abilities that had been declared valid. The data analysis technique used is the analysis prerequisite test, the average similarity test, the two-group average difference test in pairs and hypothesis testing. Hypothesis testing using independent samples t test and manova test. Based on the result of the hypothesis test of learning motivation, the significance value of 0,008 (0,0080,05) and thitungttabel (2,7642,045) this indicates that there is an effect of the scientific approach assisted by focusky on the learning motivation of junior high school students on quadrilateral material. The result of the hypothesis test of mathematical reasoning ability obtained a significance value of 0,001 (0,0010,05) dan thitungttabel (3,3402,045) this indicates that there is an effect of the scientific approach by focusky on mathematical reasoning ability of junior high school students on quadrilateral material and results of the MANOVA test obtained a significance value of Pillais Trace, Wilks Lambda, Hotelillngs Trace dan Yoys Largets Root of 0,001 (0,0010,05) which means that there is an effect of the scientific approach assisted by focusky on students learning motivation and mathematical reasoning abilities of junior high school students on quadrilateral material.

Abstract

This study aims to examine differences in critical thinking skills between groups of students who apply Autograph-aided Creative Problem Solving learning models and students who apply Creative Problem-Solving learning models without the help of autographs and see students' positive attitudes in learning Creative Problem-Solving models. This research is experimental research at YPK Medan Private Middle School. The sample selection used as the experimental group, and the control group was carried out randomly (random cluster sampling). The instrument used was a set of tests of critical thinking skills in mathematics. The results showed that the ability to think critically in students who applied the CPS model using Autograph was better, with a percentage of mastery learning by 85.27%. In comparison, the group of students who applied the CPS model gained a percentage of mastery learning by 78.16%. There was a positive attitude of students applying the autograph-aided CPS model when learning takes place.

Abstract

The innovative design of this study was to create a non-equivalent pre-test and post-test control group. The population of this study includes all Class IX students at PGRI 3 Medan Private Secondary School, consisting of 116 students, and the selected sample consists of two classes. The tools used are descriptive forms of mathematical representation tested and validated. The results of these studies showed that students who received open methods were much better at expressing themselves accurately than students who received traditional methods. Show that the open-ended approach can improve students' mathematical expression, even if the results are suboptimal because students' grades are still poor. This happens because the open-ended approach allows students to solve problems in different ways and create multiple representations of the problem.

Abstract

Research is research involving one class as an experimental class. The purpose of this study was to determine the effectiveness of using a discovery learning model to apply mathematical learning with Pythagorean material. It is related to the metacognitive abilities of eighth-grade middle school students. This study is a quasi-experimental study. The population in this study were all grade VIII students of SMP Negeri Lasten Kab, Gayo Lues for the academic year 2020/2021, which amounted to 9 classes. The sample was drawn using cluster random sampling so that a sample of Class VIII-1 students was obtained from 17 female students and 15 male students. men, as the experimental class without a control class group. The research test instrument used was an initial mathematical ability test and a student's metacognitive ability test by learning the Discovery Learning model. Analysis, descriptive analysis and inferential analysis of the data used. From the research conducted, findings (1) indicate that students' initial math skills remain low prior to applying the discovery learning model for learning. (2) The metacognitive ability scores of the learning models were found to be in the good category. Based on the results of the research conducted, it can be said that learning using the discovery learning model effectively improves the metacognitive abilities of the class VIII SMP Negeri Lasten Kab, Gayo Lues.

Abstract

In this study, the problem taken was premarital sexual behavior in adolescents in Medan City in 2021, by looking at the shift in the norms of right and wrong, good and bad, especially in the context of sexual behavior becoming increasingly real. The purpose of this study is to determine a model of premarital sexual behavior in adolescents in Medan City in 2021 by using logistic regression to carry out a prevention by looking at what variable factors have a significant relationship to the level of premarital sexual behavior that occurs in Medan City. In this study, there were 100 samples that had been taken using Cluster Random Sampling with four predictor variables, namely media, attitudes, knowledge and parental roles and the response variable, namely premarital sexual behavior in adolescents. Based on binary logistic regression, the model obtained is with the smallest G test value and each model on multiple variables, it can be seen that the entire value of Cox Snell and Nagelkerke (R2) 0.50 in the overall parameter significance test which states that the level of effective contribution given by each predictor variable to the response variable has not enough to be used as a model of premarital sexual behavior in adolescents in Medan City in 2021. This means that there are other variables besides media, knowledge, attitudes and parental roles that can affect the level of premarital sexual behavior in adolescents in Medan City in 2021
