This study aims to determine the differences in mathematical communication skills of students in the material opportunities by using PBL and CTL learning models in class X of the Al-Istiqomah Private Vocational School in the Regency of Java. This type of research is semi-experimental. The population in this study were all students of class X of Private Al-Istiqomah Vocational School, Regency of Java. The research sample was 2 classes. The results of the research obtained F_count> F table which is 15.31> 3.99, so to test the hypothesis it can be concluded that rejecting H0 means thank Ha, there are differences in mathematical communication skills of students taught using problem based learning models with students taught using Contextual Teaching learning models Lerning. There are differences in mathematical communication skills of students taught using a problem-based learning model compared to students who are taught using the 9% Contextual Teaching Lerning learning model

Tujuan penelitian ini untuk mengetahui apakah terdapat interaksi  antara model pembelajaran dengan kemampuan awal matematik siswa terhadap kemampuan komunikasi matematik siswa. Jenis penelitian ini adalah semi eksperimen. Penelitian ini dilaksanakan di SMK Swasta Al-Istiqomah Kec. Tanah Jawa.  Sampel penelitian ini terdiri dari 2 kelas eksperimen yaitu kelompok eksperimen 1 kelas X  SMK TKJ dengan jumlah 34 orang dan kelompok Eksperimen 2 kelas X TKR dengan jumlah 34 orang. Hasil analisis data terhadap tes kemampuan awal, tes kemampuan komunikasi matematis siswa menunjukkan bahwa data berdistribusi normal dan memiliki varians yang homogen. Selanjutnya untuk menjawab rumusan masalah digunakan ANAVA dua jalur. Dari hasil perhitungan ANAVA didapat kesimpulan bahwa: Terdapat interaksi antara model pembelajaran dengan kemampuan awal matematika siswa terhadap kemampuan komunikasi matematis siswa. Kata kunci: Interaksi, kemampuan Awal, komunikasi matematis

Technological progress should contribute many benefits to human welfare, especially in the education aspect. In the pandemic era, teachers are forced to be technology literate by implementing online learning. However, in reality, the use of technology in online learning becomes an obstacle because optimal learning is not achieved specifically as the government hopes. This study discusses the analysis of axiology in online learning and uses the analysis method of literature review (literature research) from several relevant sources. The purpose of this article is to provide additional knowledge and learning for teachers so that later in the education unit they are able to actualize their abilities to produce competent students according to the expectations of the nation. The results of the literature study show that online learning does not support the achievement of learning aspects when viewed in axiological studies related to ethical and aesthetic values. Students still have difficulties and have problems in online learning so that they have not given birth to personal learning motivation and lack the creativity to develop the knowledge that has been obtained from teachers through online learning. Keyword: Axiology, Technology, Online Learning..
