Abstract

Teaching aids in the world of education is a medium that mediates to help clarifying concepts in learning mathematics. This study aims to determine the efect of the use of toy car props on students’ interest in learning mathematics, especially in comparison material. This research was conducted at SMPN I Bola VII class semester 2 of the 2019/2020 scholl year. This type of research is quantitative by using a quasi-experimental methods. The population of this study were 192 studentsof class VII SMPN I Bola with a sample 0f 23 students in the experimental class and 23 from the control class. The sampling technique used is class random technique. The instrument used in this study was a questionnaire of interest in learning. Before carrying out a hypothesis test it is necessary to do a prerequisite test that is a test for normality and homogeneit. The normality test  obtained significant values in the experimental class and control were 0,136 and 0,620, because the value obtained has a significance level 0f >0,05, it can be stated that the data is normally distributed. For the homogeneity test, the results obtained a significant value of 0,001 at a sisnificant level of 0,05, so it can be said that the data is homogeneous. After the data is normally distributed and homogeneous, it is continued with hypothesis testing. Hypothesis testing used the independent sample t-test obtained value of  t-count > t-table where t-count = 6,49 while t-table = 2,01 which means that the use of toy props has an effect on the interest in learning mathematics in class VII SMPN I Bola where students’interest in learning mathematics increases. Thus the teacher can use toy props related to the material and can be used in matematics learning so that students’ interest in learning mathematics increases.

Abstract

In learning mathematics, students often experience mistakes or omissions in solving the questions given both the questions of practice, assignments, tests, and exams. This study aims to determine the student's errors mistakes in solving mathematical problems in the composition and inverse functions in SMA Negeri 1 Maumere. The method used is descriptive qualitative, with X MIPA 4 students' research subjects, amounting to 34 people who were selected based on purposive sampling technique where this subject who gets material on compulsory mathematics, namely the material composition function and inverse function. Data collection procedures are taken through the provision of test questions and interviews whit students. Data analysis includes data reduction, data presentation, and conclusions. This study results can be said that the student's errors in solving mathematical problems in the composition and inverse functions of high, medium, and low ability students make the same mistakes, namely errors in using data, language interpretation errors, and technical errors.

Abstract

Student learning outcomes are a measure of student success in the learning process in class, and this study aims to determine the quality of student learning outcomes and aspects that affect mathematics learning outcomes in the comparison of trigonometry in a right triangle based on cognitive shutter at SMK Negeri 1 Maumere. Type of qualitative research with qualitative descriptive methods. Research subjects were students of class X DPIB-2 with a total of 34 people. This study uses data collection techniques by giving test questions and interviews. The analysis technique used in this research is descriptive qualitative data reduction, data display, and verification. The results of this study indicate that the learning outcomes of students with a low criterion are sufficient, the criteria are very large in number, the criteria for high are many, very high criteria the number is lacking. While the aspects affecting student learning outcomes are internal aspects and external aspects, internal aspects include students lack of interest in learning, students lack of understanding, memory and numeracy skills, while the external aspect includes family attention and support for students to repeat the material given by the teacher at home.

Abstract

The STAD cooperative learning model can support active, independent and responsible learning for students. The application of this model is expected to improve students' critical thinking skills. The purpose of this study was to determine the improvement of students' critical thinking skills using Edmodo-assisted learning models. Edmodo was modified to become a teacher tool to expand learning at home. This research is an experimental study using a pretest-posttest control group design involving 39 students of class VIII MTs At-Taqwa Beru, Sikka, East Nusa Tenggara. Based on the results of the study it was found that the Edmodo-assisted STAD type cooperative learning model can improve students' critical thinking skills.

Abstract

This study aims to determine the effect of flight activity noise intensity on student learning concentration. This study involved 48 students (male = 24 and female = 24) who were randomly selected in the Islamic elementary school Waioti, Maumere. The intensity of flight activity noise during classroom learning activities is measured using a Sound Level Meter (SLM), and students' concentration levels were measured using a 5-level Likert scale learning concentration questionnaire. The effect of flight noise intensity on student learning concentration was determined using linear regression analysis. The results showed that the noise level due to flight activities in the Waioti Islamic Elementary School was 58.92 dB, exceeding the set threshold value. The intensity level of students' learning concentration disorders reached 71.43%, including frequent disturbance. The level of flight activity noise significantly affects student learning concentration with the regression model: Y = 49.972 + 0.834X with R2 of 0.635.
