The academic impact of online mathematics learning during COVID-19 for junior high school students

Visual Basic Application for Excel is a simple program language and has the power to process data quickly, let alone the utilization of math functions in Microsoft Excel can help work on Excel display more interactive so that teachers can create props inside Excel. The advantages of Microsoft Excel compared to mathematical software are the many math functions and images available in the form of shapes or pictures. With the availability of VBA, math and image functions in Microsoft Excel, teachers can design the creation of media related to mathematics learning especially helping to develop the ability of junior high school students who have difficulty connecting mathematics lessons with basic mathematics knowledge requirements. In general, that most students in Indonesia have not solved mathematical problems, therefore, by using VBA for Excel the ability of junior high school students to improve in the usual way significantly with a t-test with 0.006 <0.05 and there is an association between Trust self-comfidence student with students' mathematical comprehension skills with a contingency value with a significant amount of 0.016 <0.05 with a contingency coefficient of 0.525 including a moderate association

Mathematical Concepts

Pemahaman Konseptual Matematis (PKM) memiliki peran penting karena dengan kemampuan ini siswa mudah dalam membangun hubungan untuk memahamai ide dan konsep baru. Kemampuan PKM ini dapat ditumbuh-kembangkan melalui pembelajaran di kelas. Untuk mencapai kecakapan tersebut, pembelajaran perlu memperhatikan keberagaman siswa karena pembelajaran yang mengakomodasi keberagaman menjadi lebih efektif, efesien, dan menarik. Keberagam tersebut dapat berupa Gender (G), Kemampuan Awal Matematika (KAM) dan Gaya Belajar Matematis (GBM) siswa. Salah satu pendekatan pembelajaran yang mengakomodir keberagaman ialah pembelajaran pendekatan Rigorous Mathematical Thinking (RMT). Artikel ini bertujuan untuk mengkaji kemampuan PKM siswa SMP yang memperoleh pembelajaran pendekatan RMT ditinjau dari : a). Gender, b). KAM siswa, dan c). GBM siswa. Penelitian ini merupakan penelitian eksperimen pada siswa SMP di salah satu sekolah di Bandung. Salah satu hasil yang penting adalah dengan pembelajaran ini menjadikan siswa dengan KAM sedang dan rendah dapat mencapai kemampuan yang baik. The Effect of Rigorous Mathematical Thinking (RMT) Learning Approach On Students’ Understanding of Mathematical Concepts AbstractAn understanding of mathematical concepts (PKM) has an important role because with this ability students are easy in building relationships to understand new ideas and concepts. The ability of PKM can be grown-developed through learning in the classroom. To achieve these skills, learning needs to pay attention to the diversity of students because learning that accommodates diversity becomes more effective, efficient, and engaging. Such diversity can be Gender (G), An initial mathematical ability (KAM) and students’ mathematics learning styles (GBM). One approach to learning that accommodates diversity is the Rigorous Mathematical Thinking (RMT) learning approach. This article aims to examine the ability of junior high school students who have learned RMT approach in terms of: a). Gender, b). students’ KAM, and c). students’ GBM. This research is an experimental research on junior high school students in one school in Bandung. One important result is that this learning engages students with medium and low of KAM able to achieve good abilities.

Penelitian ini bertujuan untuk mengidentifikasi apakah mahasiswa calon guru matematika mampu membangun situasi didaktis matematis pada siswa SMP dalam pembelajaran matematika berbasis ICT (Information and Communications Technology). Penelitian ini adalah penelitian deskriptif kualitatif. Subjek penelitian adalah mahasiswa calon guru yang telah praktik mengajar di sekolah. Subjek menggunakan aplikasi yang dibuat sendiri oleh subjek. Aplikasi yang dibuat berupa Augmented Reality (realitas bertumbuh), yaitu teknologi yang menggabungkan benda maya dua dimensi dan atau pun tiga dimensi ke dalam sebuah lingkungan nyata tiga dimensi lalu memproyeksikan benda-benda maya tersebut dalam waktu nyata. Hasil penelitian menunjukkan karakteristik situasi didaktis dalam pembelajaran matematika berbantuan ICT pada siswa SMP yang dibangun oleh mahasiswa calon guru adalah sebagai berikut: situasi didaktis matematis yang dibangun belum mengonstruksi pengetahuan siswa secara mandiri; situasi didaktis matematis yang dibangun cenderung berasal dari informasi yang disampaikan guru, bukan dari media ICT yang digunakan; dan ICT yang dilibatkan dalam pembelajaran belum mampu mengelaborasikan proses kognitif siswa dalam jejak pembelajarannya. Analysis of a didactic situation in ICT-assisted mathematics learning in junior high school studentsAbstractThis study aims to identify whether prospective mathematics teacher students are able to build mathematical didactic situations in junior high school students in ICT-based mathematics learning. This research is descriptive qualitative research. The research subjects were prospective teachers who had practiced teaching at school. The subjects used applications made by themselves. Those applications were in the form of augmented reality (reality grows), namely technology that combines two-dimensional and or three-dimensional virtual objects into a real three-dimensional environment and then projecting these virtual objects in real-time. The results showed the characteristics of didactic situations in ICT-assisted mathematics learning in junior high school students built by prospective teacher students were as follows: didactic mathematical situations that were built had not constructed students' knowledge independently; the built mathematical didactic situation tends to originate from the information conveyed by the teacher, not from the ICT media used; and ICT involved in learning has not been able to elaborate the cognitive processes of students in their learning footprint.

And Function

This research tries to analyze the mathematics learning difficulties of Junior High school students on the material of “ relation and function”. This research was conducted on the grade VIII students in one of Junior High School 1st semester in Surakarta city in the academic year 2016. Mastery of students to the concept of mathematics which is the basic science of all sciences is still lacking. The results of the national exam of junior high school students of Surakarta are still low, one of which can be seen from the absorption of material relations and functions. This is because the results of National Examination for the city of Surakarta, can be seen from the absorption of UN value in 2015 with indicators to solve problems related to the function of 57.23%, while the year 2016 with indicators determine the value of the function if the formula of the known function of 52.70 %. This study uses test methods and interviews to find out the learning difficulties and their causes. Based on the test and interview on 3 Junior high school students who have high, medium and low learning achievements, it is found that students got difficulties in determining the value of function and value of x, if the image of x is known. Students get difficulty in solving problems related to the function and determine the value of the function and determine the value of x if the image of x is given. By knowing the difficulties faced by students expected teachers can find ways to overcome difficulties faced by students so that will be able to improve students' understanding of the material relations and functions.
