ANALISIS KESULITAN BELAJAR OPERASI PERKALIAN PADA SISWA SEKOLAH MENENGAH PERTAMA (SMP)

Mathematical learning can never be separated from the arithmetic operations of addition, subtraction, multiplication and division operations. Arithmetic operations that are still widely complained of by junior high school students or equivalent are multiplication arithmetic operations. This study aims to determine the location of students' difficulties in multiplication operations. The analysis technique in this article uses quantitative methods with descriptive and inferential statistical techniques. The subjects of this study were 25 junior high students in Lampung Province. Difficulties faced by students is that it is difficult to understand the intentions of the questions which reach 40%, these difficulties which trigger other difficulties arise. These difficulties include unit multiplication operations, tens, hundreds to thousands. Researchers collected data using a Google form web-based interactive service questionnaire by giving a test in the form of 10 story questions and a column of reasons for difficulty while working on the questions. The questions given refer to the level of difficulty, the validity of the questions with the Product Moment correlation technique for each item and the reliability that reaches 0.707 using the Cronbach Alpha method. Obtained 55% of junior high school students or equivalent difficulty when working on the problem.Keywords: Multiplication, Junior high school, Student difficulties.

PENERAPAN MEDIA PEMBEMBELAJARAN KOGNITIF DALAM MATERI PERSAMAAN GARIS LURUS MENGGUNAKAN VIDEO DI ERA 4.0

At this time thinking creativity is low in the world of education. To improve creative thinking patterns urgently, as educators must have ways to improve them. Learning mathematics can be done only through the medium of learning mathematics. Audio-visual media, is a type of media used in learning activities with hearing and vision in one process or activity. Messages and information that can be channeled through this media can consist of verbal and nonverbal messages that depend on the sight whether hearing. In this 4.0 era, students are required to be better able to think cognitive in learning. Fully creative thinking including in the current era is needed. However, at this time creative thinking in the world of education is low. To improve the importance of creative thinking patterns, as educators who already have a way to improve it by using learning media. Therefore the material explanation method is made using video-based media to facilitate students in understanding the material and also improve their cognitive abilities. This research can prove through video-based learning media can be an effective method in improving students' cognitive abilities. Keywords: Media, Video, Cognitive

PEMANFAATAN APLIKASI MICROSOFT POWERPOINT PADA SISWA SMP KELAS VIII DALAM PEMBELAJARAN KOORDINAT KARTESIUS

Learning mathematics is very important for students, based on the learning objectives of mathematics in primary to secondary education, namely to prepare students to always develop logically, rationally, critically, accurately, honestly, efficiently and effectively in the world of education. The media can increase and direct the attention of students so that it can lead to learning motivation, more direct interaction between students and their environment and the ability of students to learn on their own according to their abilities. Therefore we need a learning media that can visualize objects from cartesian coordinate material. One such visual media is Power Point which can be used to visualize work objects from mathematics. This study aims to produce learning media that can be understood by students and to determine student interest in learning by using a microscope-based powerpoint learning media on cartesian coordinate material. The method used in research is research and development and the collection technique used is direct observation. The results of trials conducted, Microsoft PowerPoint based learning media were able to attract student interest in learning.Keywords: Microsoft Powerpoint, cartesian coordinate.

PERKEMBANGAN MATEMATIKA DALAM FILSAFAT DAN ALIRAN FORMALISME YANG TERKANDUNG DALAM FILSAFAT MATEMATIKA

Mathematics and philosophy have a pretty close relationship, compared to other sciences. The reason, philosophy is the base for learning science and mathematics is the mother of all sciences. There are also those who think that philosophy and mathematics are the mother of all existing sciences. In historical terms, the relationship between philosophy and mathematics experienced a very striking development. The question arises regarding "Is mathematics an abstract science?" "What is the origin of the formation of numbers?" And questions that are difficult to be solved by mathematics itself. Therefore we need a field of science that can bridge and accommodate questions that arise. Therefore, the field of philosophy has emerged which is able to answer matters concerning the history and development of mathematics itself. This research explains some of the problems surrounding what efforts need to be made to overcome the crisis, contradictions and paradoxes in mathematics and answer the basic questions of mathematical philosophy which currently widely used to teach and develop mathematics.Keywords: philosophy mathematics, evolution of mathematics

STUDY AT HOME: ANALISIS KESULITAN BELAJAR MATEMATIKA PADA PROSES PEMBELAJARAN DARING

The e-learning study at home education system is in accordance with the 2013 curriculum. However, when the e-learning application is too difficult, it is likely that students are not able to learn mathematics optimally, as well as the amount of data that must be delivered but the internet or network access becomes slow, of course it is will disrupt student activities. This study aims to determine the learning difficulties of students towards mathematics e-learning at home. The research method used is descriptive research method. The study involved high school / MA students with data collection techniques and information through a student questionnaire response instrument using Google forms and the research subjects numbered 30 students. The student response contained 31 statement items which were the descriptions of the indicators. Indicator to measure students 'responses regarding students' learning difficulties to mathematics through the e-learning system at home. Based on the average student achievement regarding learning difficulties in mathematics e-learning that is 75% by having the lowest achievement value by students namely the implementation of interactions, assignments and teaching materials in online learning by 73% and the highest indicator achieved by students namely technical signal constraints and the inability to learn online (e-learning) that is equal to 77% and for testing the validity shows that all items are valid statements, this is because 𝑟𝑐𝑜𝑢𝑛𝑡 𝑟𝑡𝑎𝑏𝑒𝑙 and Cronbach Alpha value 0.839 reliability coefficient 0.6.
