Abstract

Counting is a branch of mathematics which is a basic skill that children need to master from an early age. In fact, the ability to count in early childhood is still very low, this is because children find it difficult to count or pronounce a sequence of numbers, count by pointing at objects and pointing to a sequence of objects. On the other hand, teachers do not take advantage of the learning media used to support children's learning outcomes in arithmetic. To overcome this problem, learning to count is carried out using educational learning media Counting Tree because by utilizing educational learning media Counting Tree (counting tree) learning to count will be easier, interesting and fun for children. This study aims to describe the implementation of learning by applying the Counting Tree educational learning media to improve the cognitive abilities of students in Kartika Tanjung Morawa Early Childhood Education. Classroom Action Research with a qualitative approach consisting of three cycles. With the research instrument used was a test of mathematical problem solving abilities. The target output to be achieved in this study is an international journal.

Abstract

The development of science at the present time requires educators to create learning innovations especially mathematics learning that is associated with cultural values. In line with the goals of the State who want to advance the national culture of Indonesia in the midst of world civilization by ensuring the freedom of the people in maintaining and developing their cultural values. With the hope of collaborating between learning with local culture, in addition to preserving the existing culture, it can also help students understand the material. Educators are also required to be able to use various methods in learning so that the learning atmosphere feels comfortable. The more methods and exercises used, the higher the level of mathematical problem solving possessed and conversely the less variety of methods and exercises used, the lower the level of mathematical problem solving of students. The purpose of this study is to improve students' mathematical problem solving abilities by applying a culture-based guided discovery method. This research uses the Classroom Action Research (CAR) method. The research instrument used was a mathematical problem-solving ability test. Output targets to be achieved in this study are journals.

Abstract

Abstrak:Tujuan artikel ini adalah memberikan informasi mengenai pengertian filsafat matematika, pengertian filsafat pendidikan dan hubungan antara matematika dengan filsafat pendidikan. Jenis penelitian yang digunakan adalah penelitian deskriptif dan studi literatur (library research). Temuan dalam artikel ini adalah hubungan  antara matematika dan filsafat pendidikan yang saling bersinergi satu sama lain. Kesamaan antara matematika dan filsafat adalah memiliki objek kajian yang sama yaitu begerak pada tingkat generalitas dan abstraksi yang tinggi, mempergunakan akal/ rasional dan tidak melakukan eksperimen, serta tidak memerlukan peralatan laboratorium. Namun, matematika dan filsafat juga memiliki perbedaan yaitu jenis metode dalam menelaah suatu kebenaran. Matematika menggunakan metode deduksi dimana kebenaran dari hasil penelaahannya harus dapat ditunjukan dengan serangkaian langkah pembuktian. Sedangkan filsafat menggunakan macam–macam metode rasional dimana proses pembuktian itu tidak harus terjadi tetapi harus berlangsung dengan alasan-alasan yang diperoleh dari penalaran serta dapat bersifat fleksibel. Kata Kunci:Matematika, Filsafat, Pendidikan Abstract:This study aims to inform the concept of philosophy in mathematics, the concept of philosophy in education, and the relationship between mathematics and the philosophy of education. This study follows a descriptive approach with a literature study (library research). The findings indicate the relationship between mathematics and educational philosophy that synergize with each other. The similarity between mathematics and philosophy is that they have the same object of study, namely dealing with a high level of generality and abstraction, using reason/rationality, not conducting experiments, not requiring laboratory equipment. However, mathematics and philosophy are also different in terms of the method in examining a truth. Mathematics uses deduction where the truth of the results of the study must be presented by steps of proving evidence. Meanwhile, philosophy uses various traditional methods where the process of proving evidence does not need to be presented, but it must take place with reasons derived from reasoning and can be flexible. Keywords:Mathematics, Philosophy, Education

Abstract

This study aims to find out there is a stress coping relationship with the motivation to learn guidance and counseling students in statistical subjects. The data collection instrument used to measure stress coping and learning motivation is the Likert scale. Coping stress is measured based on the forms of emotional focused coping stress and problem focused coping, on learning motivation measured based on the types of learning motivation that is intrinsic and extrinsic. The population of this study was guidance and counseling students and the sample of this study were 57 people. The data analysis used is Simple Correlation. The results showed that stress coping had a correlation with learning motivation with a calculated r value of 0.680> r table 0.261. In this analysis r count is positive, the relationship between the two variables is directly proportional, namely the increasing stress coping will increase student learning motivation in statistical subjects, on the contrary the decrease in stress coping will decrease students' learning motivation in the statistics course.

Abstract

This study aims to find out (1) How students' mathematical understanding ability of IX MTs S Nurul Amaliyah Tanjung Morawa prior to the implementation of Think Talk Write (TTW) strategy on the subject of How Matching Numbers (2) How Student Mathematical Understanding Ability IX MTs S Nurul Amaliyah Tanjung Morawa after the implementation of the Think Talk Write (TTW) strategy on the topic power of numbers. The method used in this research is classroom action research. From the results of observation and ability test in solving the problem of the numbers of rank given to the students, found the location of student errors are: students are less interested in learning mathematics, students do not know what is known from the problem and students are less thorough in solving the problem. The percentage of classical completeness and the average grade of the initial test classes are still low at 27.5% and 54.63. Implementation of think talk write strategy can improve student learning outcomes. This is marked by increasing the percentage of classical completeness and grade point average in the first cycle by 40% and 56.88 to 67.5% and 67.00 in cycle II and to 92.5% and 77.50 at the end of cycle III . Application of Think Talk Write strategy is also able to improve students' mathematical understanding ability. It can be seen by the percentage in the first cycle of 58.03% to 66.24% in cycle II and to 76.24% at the end of cycle III.

Abstract

This article will discuss the communication skills of SMP IT Al Ikhwan students in class VII-1 and VII-2 each with a total of 32 students, after being given learning through RME. Determination of the sample is done by simple random. The research instrument used in this study was a test that was statistically analyzed using N-Gain. After carrying out a series of activities starting from the pretest, treatment and posttest, it can be concluded that the use of RME was apparently good for improving mathematical communication skills as seen from the N-Gain acquisition for each class that was sampled. The learning process that uses RME opens opportunities for students to be able to play a more active role in expressing themselves in solving mathematical problems and realistic mathematics education gets a very good response, students really like it and feel very excited.
