Online learning is a learning interaction solution during the Covid-19 Pandemic. A Learning Management System (LMS) is essential to facilitate the implementation of online learning. Teachers can use many LMS. Schoology and Google Classroom are LMS that teachers can use in online learning. However, the facts show that most junior high school teachers need help utilizing Schoology and Google classrooms in online learning. Therefore, technical guidance activities are carried out to increase teacher knowledge, understanding, and skills in utilizing Schoology and google classroom in online learning. The method used in this activity is job training, divided into off and on-the-job training. Off-the-job training is carried out to increase teachers' knowledge and understanding of the use of Schoology and google classroom in online learning. The resulting output is an increase in teacher knowledge and experience as indicated by the n-gain between the scores before (pretest) and after (posttest) attending the training. On-the-job training is carried out to improve the skills of teachers in utilizing Schoology and google classroom in online learning. The results of this activity show an increase in teacher knowledge, understanding, and skills in using Schoology and google classroom in online learning.

Teachers' understanding and skills in developing teaching materials are absolute requirements that teachers must have. In reality, the understanding and skills of junior high school mathematics teachers in South Lampung in developing teaching materials, especially geometry, are still low. This has implications for the low quality of learning which has an impact on students' low geometry abilities. One of the geometric materials is circles. The teacher views that circle material only contains a collection of formulas so that learning is mechanistic and dogmatic. Therefore, it is necessary to carry out training to improve the understanding and skills of junior high school mathematics teachers in South Lampung in developing circle teaching materials. This activity involved 26 junior high school mathematics teachers in South Lampung as participants. This training method takes the form of presenting material and workshops. Activities are carried out through presentation of material, discussion, group work and presentation of work results. Activity data is in the form of teacher understanding and skill scores in developing circle teaching materials obtained through pretest and posttest. Data analysis was carried out using descriptive statistics. The results of data analysis show that as many as 80% of teachers have initial understanding and skills that are not yet good. After attending the training, as many as 96.15% of teachers had relatively high levels of understanding and skills. Thus, this training is effective in increasing teachers' understanding and skills in developing circle teaching materials.

Penelitian ini bertujuan untuk mengeksplorasi dan menganalisis konsep-konsep matematika yang terdapat dalam motif Sikop Arrum Batik Tulis Lampung di Kampung Baru, Kota Bandar Lampung, sebagai bentuk penerapan etnomatematika dalam budaya lokal. Penelitian ini merupakan penelitian kualitatif dengan metode deskriptif, dengan subjek satu pengrajin batik dan objek berupa tiga motif batik, yaitu motif Sembagi, Gajah, dan Kopi. Data dikumpulkan melalui observasi menggunakan lembar ceklis, wawancara semi-terstruktur, dan dokumentasi foto, dengan peneliti sebagai instrumen utama, kemudian dianalisis melalui reduksi data, penyajian data, dan penarikan kesimpulan serta diuji keabsahannya melalui triangulasi teknik. Hasil penelitian menunjukkan bahwa ketiga motif batik memuat berbagai konsep matematika yang diterapkan secara intuitif oleh pengrajin, meliputi unsur geometri (titik, garis, dan sudut), bangun datar, kesebangunan, kekongruenan, serta transformasi geometri (translasi, refleksi, rotasi, dan dilatasi), di mana motif Sembagi menonjolkan pola grid dan translasi, motif Gajah menunjukkan refleksi dan simetri, serta motif Kopi memperlihatkan rotasi dan bentuk bangun datar seperti elips, selain itu seluruh motif menampilkan pola berulang, simetri, dan proporsi yang mencerminkan keterkaitan antara estetika batik dan prinsip geometri. Temuan ini menunjukkan bahwa batik tradisional Lampung tidak hanya mencerminkan nilai budaya, tetapi juga memiliki potensi sebagai sumber belajar kontekstual dalam pembelajaran matematika berbasis etnomatematika sehingga dapat membantu siswa memahami konsep matematika secara lebih konkret dan bermakna dalam kehidupan sehari-hari.

Mathematical representation ability is the competence to present mathematical ideas in symbolic, visual, or verbal forms. This descriptive qualitative research aims to analyze students' errors in solving statistics problems based on mathematical representation ability, conducted through a literature study. The results indicate that students still have difficulty representing mathematical ideas (symbolic, visual, verbal). Key errors include conceptual errors (selecting formulas), inaccuracy in charts/diagrams, and inability to connect the data context with its representation. The contributing factors are the lack of conceptual understanding and a focus on procedures. This finding is expected to serve as a reference for teachers to strengthen students' mathematical representation ability, particularly in statistics material.

This study aims to analyze how junior high school students express their ideas when solving problems related to the System of Linear Equations in Two Variables (SPLDV). Mathematical Representation Ability is essentially a "bridge" for students to transform difficult and abstract mathematical concepts into more real and simple forms, whether through images, symbolic formulas, or written explanations. SLETV was chosen due to its characteristics that involve complex word problems, requiring students to be proficient in converting long narratives into correct mathematical models. Through a literature review method analyzing various previous research findings, it was found that students' representation abilities are heavily influenced by their basic mathematical proficiency levels. High-achieving students are generally proficient in using symbols and graphs, yet they still face challenges in providing narrative explanations for their reasoning. Meanwhile, low-achieving students and slow learners show significant obstacles in initiating problem-solving, thus requiring specific assistance or scaffolding.
