The aim of this research is finding students' mathematical problem-solving skills based on high, medium and low initial knowledge. This research is a quasi-experimental study. The research sample used students in VIIIA and students in VIIIB SMPN 1 Kerinci that selected using random sampling techniques. The research data were processed using the t-test and the Mann Whitney test to comparing students' problem-solving skills that using active learning strategy sorting cards and problem-solving skills of students using ordinary learning. The result of data analysis showed that the mathematical problem-solving skill of students with high, medium and low initial knowledge was better than the mathematical problem-solving skill of students with the same initial knowledge that used ordinary learning. Penelitian ini bertujuan untuk mengetahui perbandingan kemampuan pemecahan masalah matematika siswa berdasarkan pengetahuan awal tinggi, sedang dan rendah. Penelitian ini merupakan penelitian eksperimental semu. Sampel penelitian yang digunakan adalah siswa di VIIIA dan siswa di VIIIB SMPN 1 Kerinci yang dipilih menggunakan teknik random sampling. Data hasil penelitian diolah menggunakan uji t dan uji Mann Whitney dengan tujuan membandingkan kemampuan pemecahan masalah siswa yang menggunakan strategi belajar aktif sortir kartu dan kemampuan pemecahan masalah siswa yang menggunakan pembelajaran biasa. Hasil penelitian menunjukkan bahwa kemampuan pemecahan masalah matematika siswa dengan pengetahuan awal tinggi, sedang dan rendah lebih baik daripada kemampuan pemecahan masalah matematika siswa dengan kemampuan awal yang sama yang menggunakan pembelajaran biasa.
This research was started by the lowerness of students’ mathematical reasoning ability at VII grade of SMPN 1 Kerinci. That’s obtained from the student’s semester examination result then according to the experience, observation and interview results with the junior high school mathematic teachers. The aim of this research is to analyze the effect of Problem Based Instruction (PBI) Model through student’s reasioning ability at VII grade of SMPN 1 Kerinci. This research is using quasy experiment method with Randomized Group Control Only Design. The population is all of seventh grade students in SMPN 1 Kerinci. This research is using Random Sampling Technique that students at VII-C grade as experimental group and VII-A grade as control group. The research instruments in this study is mathematical reasoning ability test to obtain students mathematical reasoning ability. The data is not have normal distribution so that we used Mann Whitney-U test with SPSS helped, obtained Sig (1-tailed). value = 0,000 α = 0,05 so that rejected H0. According to the analyzed of the data, the conclusion obtained that student’s mathematical reasoning ability who learn with using PBI Model is better than using conventional learning.
This study aims to conduct a literature review related to the ability of students' mathematical representation of learning styles. The method used in this research is SLR (Systematic Literature Review). Data collection is done by identifying or reviewing all articles that have the same research topic in this study. The articles used in this study were 20 journal articles obtained by the Google Scholar database using the Harzing's Publish or Perish application. The results of this study revealed that the students' mathematical representation ability on learning styles obtained information that found forms of learning styles in the articles collected that focused on learning abilities, learning styles, and their representation. Which in this case only takes on visual, auditory, and kinesthetic learning styles. The results of this study are expected to be beneficial for learning and be used as examples of the use of various mathematical concepts around us.
This study aimed to identify students' misconceptions on the topic of function. The research used is qualitative research using a descriptive approach. The subjects of this study were class X MIA3 selected by using purple sampling and snowball techniques. The research instrument was a written test using diagnostic test techniques for misconceptions, interviews, and observations. The qualitative data analysis techniques in this research are data reduction, data presentation, and conclusion drawing/verification. Based on the research, there are 4 students who experience misconceptions in class X MIA3 on the topic of the functions. Out of 6 indicators of misconceptions, the reasons were caused by a lack of student interest in learning, underestimating the concept of functions so that they think learning the concept of functions is very easy, embarrassed to ask questions when studying, and never repeat lessons at home so that students cannot answer questions given by the teacher.
Connection ability is one of the most important higher order thinking skills and must be developed because in learning mathematics every concept is related to one another. The learning model that is able to hone mathematical connection skills is self-directed learning (SDL). Individuals who have high self-directed learning are individuals who are proactive, have their own initiative, are resourceful, and are individuals who have a responsibility to always learn. This study aims to conduct a literature review related to the Self-Directed Learning model and the ability of mathematical connections. The research method used in this study is the SLR (Systematic Literature Review) method. Data collection is done by documenting all articles that have similar research in research reports. The articles used in this study were 15 national journal articles obtained from the Google Scholar database using the Harzing's Publish or Perish application. Based on this research, it was found that self-directed learning is an independent learning model that can motivate students in learning and can make a student continuously seek information in order to improve abilities. The learning model that is able to hone mathematical connection skills is Self-Directed Learning (SDL).
Mathematics learning will be more meaningful if it uses a cultural context. Therefore an exploration of the mathematical ideas that exist in a culture is needed. The purpose of this study was to determine the fundamental ethnomathematics activities in the process of making beads basket craft and to identify mathematical concepts in beads basket craft. This research is a qualitative research with ethnographic research. The subject of this research is the bead craftsman community in Sungai Tutung, Jambi, Indonesia. The results of this study found that the activity of making bead basket crafts involved counting (e.g. determining the number of colors of each type of bead to be used), locating (e.g. placing beads to make a pattern), measuring (e.g. measuring the length of the rope), designing (e.g. designing bead basket motif), and explaining (e.g. explain the meaning of the motif on the bead basket). In addition, it was also found the concept of geometry and the concept of social arithmetic on the beads basket craft. The researchers recommend using the results of this study in learning mathematics either through direct learning or through the use of learning media.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
