Abstract

It is well known that many students do not like mathematics because they lose that mathematics is difficult to learn. The impact of the Covid-19 pandemic has caused the teaching and learning process in schools to be diverted to using online methods such as Whatsapp, Google Classroom and others.Online learning or learning systems are considered less effective, because students have difficulty understanding subject matter, especially mathematics. In addition, students underestimate this online learning system as a result, sometimes they forget the assignments given by their teacher/lecturer and tend to use their free time by playing rather than studying. There are also cases where students cannot participate in online learning activities because they do not have facilities such as mobile phones, laptops or computers. This situation is usually experienced by students who live in remote villages and often the internet network in the village is still weak due to hampered learning activities. This condition causes the motivation and interest in learning mathematics to decrease significantly. The service team has held community service activities (PKM) with the theme "Recreational Mathematics Socialization for Elementary and Middle School Students in Paowan Hamlet to Increase Motivation and Interest in Learning Mathematics"

Abstract

One of the external factors that can affect student learning outcomes is the family environment, in this case, the attention of parents. Research has been carried out to determine whether or not there is an influence of parental attention on student learning outcomes in mathematics. This research is a quantitative study using the Ex-Post Fact method . Sampling was carried out using a probability sampling technique of the simpler random type which was carried out on 111 respondents consisting of class X and XI at SMK Khamas Asembagus. Data collection techniques used are observation, documents and questionnaires. The results showed that 0.237 > 0.1865 at Cronbach's Alpha = 0.1865, this indicates that the instruments used in this study are valid and reliable. Meanwhile, the results of the T test were 2.545 > 1.65895 (with ) and the Effectiveness of the Regression Line (EGR) was 3.25% which indicated that there was an influence of parental attention on student learning outcomes in Mathematics Subject of 3.25%. Based on the results of the analysis of research data, it can be concluded that the alternative hypothesis (Ha) is accepted and the null hypothesis (H 0 ) is rejected, meaning that there is an influence between parents' attention to student learning outcomes in Mathematics Subject which is equal to 3.25%.

Abstract

This study aims to determine the influence of external factor in the scope of the school student learning outcomes in mathematic subjects specialization in class X sciences in Panji 1 Senior High School. In this study examined 3 independent variables contained in external factors in the scope of the school, namely the learning methods used by teachers, learning media, and socializing. This study in determining respondents using the proportional random sampling method, which consists of 177 populations of class X science students and taken 100 students as samples. The research design used was ex-post facto design. Retrieval of independent variable data using a questionnaire and Likert scale. Bound Variable Data using the method of documentation. Data analysis uses multiple linear regression analysis. The results of data analysis obtained the value of the correlation coefficient (r-count) of 0,014 and F count of 0,443, while F table of 2,70 at N = 100 with a significance level 5% means F count < F table .

Abstract

As the rice harvest approaches, most of the farmers in Suboh Village, Suboh District, and Situbondo Regency are still very dependent on the slashing system by middlemen. However, there is something that makes researchers interested, namely when middlemen carry out calculations to determine price bids to farmers with special tricks. Researchers believe that these activities are full of mathematical concepts that the middlemen themselves may or may not be aware of. The purpose of this study is to examine the relationship between mathematics and culture, especially in the activities of middlemen in the farmer's rice harvest slash system. This research is classified as qualitative research with an ethnographic research design. The research subjects in this study were 3 middlemen who were selected by purposive sampling area and used to buy agricultural commodities from rice farmers using the slashing system in the fields. The data in this study are data taken or collected directly by researchers from research subjects/informants, including observation data and (semi-structured) interview data. Data analysis techniques go through the stages of data reduction, data presentation, conclusion, and verification. The results showed that there were some fundamental mathematical activities carried out by middlemen, namely measuring, designing, locating, playing, counting, and explaining. While the mathematical concepts seen in this activity include the concepts of length and width, the area of ​​a rectangle, arithmetic sequences and series, profit and loss, and logic.

Abstract

AbsrtactMathematics is one of the compulsory subjects taught at all levels of education. a model is neededto support students' needs to improve students' understanding of concepts. The CORE learningmodel with the Student facilitator and explaining strategy is very good in improving students'understanding of mathematical concepts. The purpose of this study was to determine theeffectiveness of the CORE model with a student facilitator and explaining strategy on students'understanding of mathematical concepts. This study uses a quantitative method with a quasiexperimental approach and a non-equivalent control group design. the author conducted a test ofvalidity, normality, homogeneity and reliability of the test to determine the correctness andsuitability of the instrument used. From the calculation results, the results of the test have a validvalue and have a normal distribution. For the homogeneity and reliability test, all items werehomogeneous. The calculation using the Crombach alpha reliability test was obtained for all itemsmore than 0.05, so all items on the test were appropriate or reliable. It is known that the results ofthe t-test analysis in the experimental class have an average value (mean) of 63.7 post-test andpre-test of 47.5, the increase in the average result is known to be 16.2 for all test results. Inaddition, from the results of the percentage of the effectiveness of the model category, the result isa value of 63.75. So, from these results the category of effectiveness of the learning model isincluded in the category of quite effective. Keywords: Effectiveness, CORE Model and Student Facilitator and Explaining Strategy, Understanding Mathematical Concepts

Abstract

The purpose of this study was to determine the effect of using Geogebra software on student learning outcomes on the quadratic function material in Class X MA Sarji Ar-Rasyid Situbondo. The research method used a quasi-experimental research design with data collection techniques used, namely pretest and posttest. The data analysis technique used the normality test, homogeneity test, and t-test. From the t-test analysis, results obtained sig 0.263> É‘ 0.05. So it can be concluded that there is no significant effect between students taught by learning GeoGebra software with conventional learning. This result is due to students' low ability and experience in using Geogebra software for mathematics learning.
