Abstract

This research intends to describe the application of the Realistic Mathematic Education (RME) approach to profit and loss material of the VII B grade at MTs Nurul Falah Palu. This type of classroom action research (PTK). Design used in this classroom action research was Arikunto’s that consisted of planning, action, observation, and reflection. The Subject of this research were 20 students of class VII B MTs Nurul Falah Palu. This research was conducted in two cycles. The results showed that in the final test cycle I there were 11 students who completed and 9 students did not complete with a percentage of classical learning completeness reaching 55%, while in cycle II there were 16 students completing and 4 students not completing with a classical learning completeness percentage reaching 80%. The observation results in cycle I showed that the activities of teachers and student groups were in the good category, while in the second cycle the activities of teachers and student groups were in the very good category. The results of this study indicate that the application of the Realistic Mathematic Education learning approach can improve student learning outcomes on the profit and loss material of class VII B grade at MTs Nurul Falah Palu through the following steps:1) understanding the contextual problems, in this stage the teacher presented contextual problems in LKPD and students discuss in their groups to understand the problems given by the teacher, 2) Explaining the problem, the teacher provides help if its needed in the form of questions that can direct students to solve problems 3) solving the problem, students in each group work together to solve the problems through following working steps of LKPD 4) comparing, and discussing the answer, each of group representative presents their answer in order from problem solving and the other member of group compare the answer they have to answer presented by the other group, 5) concluding, teacher guided students to conclude material they just learn. The props used are play money.

Abstract

This study aims to obtain information related to whether there are differences in students' mathematics learning outcomes between offline and online learning at SMP Negeri 1 Palu. The research method used in this study is the comparative method. The population in this study were all grade VII students of SMP Negeri 1 Palu with a total of 352 students. The research sample was grade VII students who carried out offline and online learning, with different samples but had the same level of academic ability. The sampling technique in this study was Purposive Sampling. The researcher took 32 class A students and 32 class B students, so the number of samples taken was 64 people. The data collection technique in this study was by taking mid-semester test scores on the material Linear Equations and Inequalities of One Variable in the 2021/2022 Academic Year obtained by students during online learning and mid-semester test scores on Linear Equations and Inequalities of One Variable in the 2022/2023 Academic Year obtained by students during offline learning. On condition that the material taught is equivalent during offline and online learning and students have the same level of academic ability. The collected data is then processed using t-test statistical analysis. Based on the data analysis obtained: (1). The results of learning mathematics during online learning obtained an average value of 71.94; (2). The results of learning mathematics during offline learning obtained an average value of 58.56; (3). Sig. value. (2-tailed) 0.00 <0.05. This means that H0 is rejected and Ha is accepted. So the results of the study show that there is a difference in the results of learning mathematics of students taught with offline learning and online learning.

Abstract

This research aims to obtain a description of the use of mathematics in the activities of carpenters and masons in the process of building a house. The subjects of this research were two builders who were carrying out construction in the village of Tokala Atas. The two craftsmen chosen as research subjects consisted of a masons and a carpenter. The research method used was qualitative with a descriptive type of research carried out in the village of Tokala Atas. The data collection techniques used were observation and interviews. Observations were made while the builders were building the house. Interview techniques were used to explore the data that had been obtained when the observations were made. The results of the research show that carpenters and masons use mathematical concepts in building houses, namely the Pythagorean concept when forming foundation angles and measuring the sloping sides of roofs. The concept of alignment when measuring foundation bow plank strings, measuring brick laying benchmark strings and measuring frame heights. The concept of comparison is used when measuring into the foundation and when determining the distance between floor girders. The concept of flat construction is used when making sloping reinforcement frames, making piles and forming wooden joints. The concept of perpendicular lines is used when adjusting the straightness of poles, sills and roof posts. Arithmetic concepts are used when calculating zinc and teal requirements. The mathematical concepts contained in house buildings made by carpenters are roof shape: roof shape, rice wrapper and wall shape: betel stacking shape, plate stacking and lengthwise.

Abstract

This research aims to obtain a description or portrayal of the conceptual understanding of 8th-grade students in class G at SMP Negeri 3 Palu in solving statistics problems, with a focus on gender differences. This study adopts a descriptive research design with a qualitative approach. The research subjects are 8th-grade students in class G at SMP Negeri 3 Palu. Data were collected through written tests and interviews. The results of this research indicate that male students have a better conceptual understanding compared to female students based on conceptual understanding indicators. Male students can fulfill four out of five indicators, while female students fulfill three out of five conceptual understanding indicators. Both male and female students can articulate the concepts of mean, median, and mode in their own words. They can present data in table form with the correct arrangement. Male and female students can solve mean problems using appropriate algorithms. Male students can classify modes, whereas female students struggle to classify modes accurately. Both male and female students find it challenging to associate the concept of median with the concept of mean.

Abstract

This study aims to profile the completion of HOTS questions on the conical surface area material by SMP Negeri 1 Kasimabar students based on differentiated cognitive levels. This type of research is qualitative research. The subjects of this study were 2 students of different genders taken from class IX SMP Negeri 1 Kasimbar. The research subjects were one student with high mathematics ability with female gender (LN), and one student with high mathematics ability with male gender (MS). The data collection techniques in this study were written tests and in-depth interviews. The test given to the research subjects was a HOTS problem test on cone surface area material at the cognitive level of analyzing (C4). The results of this study indicate that the profile of solving HOTS problems on the surface area of the cone by students with high mathematics ability LN at the cognitive level of analyzing is correct, because the subject can distinguish information, organize by creating a structure in systematic problem solving and attribute by making conclusions based on the information obtained very well. While the profile of HOTS problem solving of cone surface area by MS high mathematics ability students at the cognitive level of analyzing is good, because MS subjects are also able to distinguish information and organize by creating structures in systematic problem solving, it's just that at the stage of attributing MS subjects are still lacking, because at the stage of attributings
