Mathematics is a subject that is extensively used in real-life situations, but it has been found to be a difficult subject to master. Accordingly, mathematics anxiety has been found to be highly prevalent in students’ lives, whereby learning styles have been underlined as one of the factors that may impact attainment of mathematics skills. This study aims to determine the relationship between learning styles and mathematics anxiety. The correlational study was conducted by using questionnaire adapted from Dunn and Dunn Model and Mathematics Anxiety Scale; involving 389 secondary school students located in the southern region of Malaysia. The study's findings revealed a positive correlation and distinguished between learning styles and mathematics anxiety. It shows that learning styles have an impact on mathematics anxiety. Hence, this study helps the students to embrace and improve their learning styles to minimize the level of anxiety towards mathematics, while the teachers may find it useful in guiding the students to control their mathematics anxiety.

Background: The learning process in mathematics significantly impacts students' comprehension, particularly due to the scarcity of practical learning tools for understanding mathematical concepts. This challenge has led researchers to focus on developing innovative and practical learning media to enhance students' grasp of these concepts. Aim: This study aimed to determine the effectiveness of a math book based on Google Sites, assessing its validity, practicality, and impact on students' understanding of mathematical concepts. Method: The Research and Development (R&D) approach was employed using the ADDIE model, which includes Analysis, Design, Development, Implementation, and Evaluation. The study involved 61 students, with 30 from class VII D as the experimental group and 3

The purpose of this research is to 1). Knowing that there are differences in students' mathematical communication abilities with the Problem Based Learning (PBL) learning model assisted by GeoGebra Software and conventional learning models. 2) Find out which learning model is better between the Problem Based Learning (PBL) learning model assisted by GeoGebra Software and the conventional learning model for students' mathematical communication abilities. 3) To determine the influence of student activity on students' mathematical communication skills who use the PBL (Problem Based Learning) learning model assisted by GeoGebra Software. 4) To find out whether students' mathematical communication skills who use the Problem Based Learning (PBL) learning model assisted by GeoGebra Software achieve individual or classical mastery. The research method used in this research is the Quasi Experimental method. The sampling technique uses purposive sampling technique. The instruments for collecting data in this research are Pre-test and Post-test. . The population of this study were class XI students of SMAN 1 Wedung. The N-Gain test is the data analysis technique used in this research. The results of this research show that the N-Gain score in the experimental class (PBL method assisted by GeoGebra) is 62%. Meanwhile, the N-Gain score in the control class (conventional method) was 54%. In other words, it can be concluded that the mathematical communication skills of students who received PBL learning assisted by GeoGebra were significantly more effective than students who received learning using the conventional method

This research is development research that designs products in the form of e-module mathematics for class XI SMA/SMK/MA. This research is focused on the feasibility of the product developed by involving validation from media experts and material experts. The purpose of this research is to develop teaching modules for students in the form of e-modules with mathematical logic material using the 4D model, namely. definition, design, development and dissemination phases. In this study, the development procedure was carried out up to the develop stage because the time for making and validating the product was limited. Data collection techniques were carried out using observation sheets consisting of media expert observation sheets and material expert observation sheets. The data analysis technique refers to the Likert scale and the results are described qualitatively. This mathematical logic e-module was first validated by media and materials experts as well as a student survey. The average percentage of the material expert's assessment was 87.5%, the percentage of the media expert's assessment was 86.8%, and the percentage of the student's conformity assessment was 86.2%, which means that the media from the e-module can be used in a very good category. Thus, this mathematical logic e-module product can be used in mathematics-logic material and can be utilized in teaching mathematics for class XI SMK

Guru di Indonesia memiliki banyak kendala terkait pekerjaannya karena banyak di antaranya yang diadili di pengadilan terkait pekerjaan profesionalnya karena tidak seperti pekerjaan profesional lain yang diberikan kekebalan hukum, guru tidak memilikinya di dalam menjalankan tugasnya. Hal ini mendorong penulis untuk mempelajari kelemahan sosialisasi dan perlindungan hukum terhadap hak guru sebagai tenaga pendidik profesional di Jawa Tengah dan bagaimana aplikasi Konsultasi E-Law membantu mereka ke dalam studi yuridis-empiris. Hasil penelitian menunjukkan bahwa kelemahan perlindungan hukum terhadap guru adalah terutama karena kurangnya pemahaman hukum dan Konsultasi E-Law dapat menjadi sarana untuk membantu guru dalam menangani permasalahan hukum terkait profesinya sebagai guru.

Kondisi di Desa Karangpaing Penawangan Grobogan menunjukkan bahwa mayoritas penduduknya 80% petani, 5% pedagang dan 5 % PNS dan 10 % buruh tani. Berdasarkan info dari Pemerintah kabupaten Grobogan yang sedang menggalakkan kegiatan kewirausahaan yaitu melalui usaha perikanan. Desa Karangpaing memiliki potensi untuk mengembangkan perikanan karena daerah Desa Karangpaing dialiri oleh aliran irigasi bendungan Kedung Ombo sehingga memudahkan masyarakat dalam budidaya ikan, berdasarkan data dilapangan menunjukkan bahwa sebagian kecil masyarakatnya pernah mencoba usaha perikanan ikan lele tetapi belum ada yang sukses, hal ini dikarenakan kurangnya pemahaman dan teknis yang baik. Oleh sebab itu perlu diperkenalkan budidaya ikan yang lain seperti ikan patin yang nilai jualnya lebih tinggi dan lebih tahan terhadap hama dibanding ikan lele biasa. Hal ini menjadikan kami harus melakukan kerjasama dengan RW 1 dan RW 2 desa Karangpaing. Tujuan utama yang dibidik adalah mengembangkan kembali semangat warga untuk berwirausaha dalam bidang perikanan, menjadikan Desa Karangpaing menjadi sentra budidaya ikan patin dan meningkatkan taraf hidup warga. Target pada tahun pertama adalah warga RW I dan RWII mampu membuat tempat pembibitan ikan patin, memproduksi ikan patin, membuat variasi olahan ikan patin dan mampu memasarkan produk ikan patin. Kegiatan yang sudah dilakukan adalah 1) Penyuluhan tentang budidaya ikan Patin dan desain kolam ikan, 2) pembuatan kolam ikan patin 3) pelatihan tentang pembuatan variasi olahan ikan Patin dan packing hasil olahan, 4) workshop tentang strategi pemasaran produk ikan Patin. Dalam pelatihan variasi olahan ikan patin telah dilakukan pelatihan pembuatan variasi olahan ikan patin yang diikuti 2 kelompok yaitu gendhing jaya dan Nambangan Jaya dengan hasil olahan seperti pepes ikan patin, kripik kulit ikan patin, abon ikan patin dan nugget ikan patin, masyarakat sangat antusias mengikuti dan melakukan produksi secara mandiri.

In learning during the current epidemic, students cannot meet face to face on campus, and learning geometry in universities is a dreadful lesson before the pandemic. Both at UPGRIS and other private universities so far, students are required to use a compass and ruler in making flat shapes and building spaces so they have to face to face with the lecturer, but now it can't because it is still online. So it is necessary to make learning media that aims to help students sketch flat shapes and build spaces virtually with practice making it online with a van Hiele theory approach, so the resulting product is truly capable of teaching. The result of this study is a virtual geometry lab application with van Hiele theory that is valid according to material and media experts with an average score of 93 and can be used in classrooms. At PGRI University Semarang, 96% of students agreed that virtual media improved students' spatial ability.
