Abstract

The purpose of this study was to increase students' interest in learning mathematics by using Active Knowledge Sharing learning on the subject matter of the composition of two functions and inverses of a function. This research is classroom action research (CAR). The subjects in this study were students of class XI IPA 2 Siabu High School consisting of 16 female students and 5 male students. The results of the study after using Active Knowledge Sharing learning were seen in the results of the questionnaire interest in mathematics learning for students in cycle I with an average of 60,23% while the average cycle II was 81,78%. Judging from the results of the cycle I mathematics learning test with a percentage of completeness of 38,10% while the second cycle the percentage of completeness was 85,71%. The results of the observations of student activities in the first cycle averaged 76,15% while the average cycle II was 89,80%. From the results of this study it can be concluded that using Active Knowledge Sharing learning can increase students' interest in learning mathematics in SMA 2 Siabu on the subject of the composition of two functions and the inverse of a function.

Abstract

The low ability of creative thinking and student learning outcomes becomes the discussion of this study. To overcome this problem, in this study applied the Contextual Learning Model. the purpose of this research is useful to answer whether there is an increase in creative thinking skills between contextual learning models and conventional learning models then to find out whether there are differences in mathematics learning outcomes in a positive direction through this contextual learning model. The type of research used in this research is experimental research where the population of this study is all students of Class X Padangsidimpuan 6 High School. Data analysis using the t-test statistical test. Based on the results of the calculation of the hypothesis test the value of t count > t table or 2.007 > 1.667 (with α 0.05), so Ha is accepted and H0 is rejected. This means that there is a significant increase in creative thinking skills in the experimental class compared to in the control class.

Abstract

ABSTRACT The problem in this study is the low self-efficacy learning of students in learning mathematics. To overcome this problem, in this study applied the Learning Learning model. The objectives of this research are: 1) to find out the increase in student self-efficacy learning through the Discovery Learning learning model in SMA 1 Sipirok, 2) to find out the Discovery Learning learning model can increase the activity of students in 1 Sipirok Public High School. quasi experiment. The study population was all students of class X SMA N 1 Sipirok TP. 2017/2018. The sample of this study was the class X MIA-2 students totaling 35 people as the experimental class and the X MIA-4 class totaling 35 people as the control class. Data analysis uses the t-test statistical test, before the data is analyzed first, a data analysis test is conducted, namely the normality and homogeneity test. Based on the results of the calculation of the hypothesis test the value of tcount> ttable or 2.007> 1.667 (with α 0.05), so Ha is accepted and H0 is rejected. This means that there is a significant increase in self efficacy in the experimental class compared to the control class. Keywords: Discovery Learning, Self Efficacy Learning, Student Activities

Abstract

AbstractThis study aims to determine: the influence of students' mathematical critical thinking analysis in solving mathematical problems through the reward and punishment method in SMA Negeri 1 Batang Angkola. The type of research used is quasi-experiment with pre-test-post-test control group design. The population in this study consisted of all class X students of SMA Negeri 1 Batang Angkola, while the sample consisted of 20 students in class X-1 as an experimental class and 20 students in class X-2 as a control class. Sampling is done through purpose sampling technique. The research instrument used was a test of students' mathematical critical thinking skills. Statistical hypothesis testing in this study used the t test. The effect of the ability of mathematical critical thinking students who get learning with reward and punishment learning is higher than students who get regular learning. With the results of the calculation obtained, then t count = 1.85 and at the level of α = 0.05 and dk = 20 + 20 - 2 = 38 then obtained t table = 1.54. Thus it is concluded that tcount> t table or 1.85> 1.54, so Ha is accepted and H0 is rejected. This shows that students' critical mathematical thinking is good enough. With reward and punishment learning makes students more active, enthusiastic and independent. This means that the influence of critical thinking in mathematics mathematics learning of students towards reward and punishment learning is better than students' critical thinking of mathematics by using ordinary learning in class X of SMA Negeri 1 Batang Angkola. Keywords: Critical Thinking, Reward and Punishment, Mathematical Problems

Abstract

Academic procrastination is a behavior to procrastinate in starting work or completing academic assignments given by lecturers. Academic procrastination is influenced by several factors including time management, academic confidence/ability, attention disorders, social factors, personal initiative, and laziness. Time management is the ability to manage time effectively and efficiently when carrying out an activity that leads to a specific goal. This study aims to determine whether there is a relationship between time management and academic procrastination in students of the Nursing Science Study Program (S1) at STIKes Medistra Indonesia in 2022. This research method uses a correlational research design with a cross sectional approach. The population in this study were regular active students of the Nursing Science Study Program (S1) at STIKes Medistra Indonesia from level I, level II, and level III totaling 197 students. After entering into the Slovin formula, the number of samples in this study was 132 students using the Probability Sampling method with the type of Simple Random Sampling. From the results of the Chi-Square statistical test obtained p value of 0.000, it can be concluded that p value (0.000) < value (0.05), this indicates that there is a relationship between time management and academic procrastination in nursing students (S1 ) at STIKes Medistra Indonesia. Time management can affect academic procrastination. So the better time management owned by students, the lower academic procrastination carried out by students and vice versa
