Abstract

Strategi blended learning merupakan pencampuran dua atau lebih strategi pembelajaran untuk mendapatkan hasil belajar yang diharapkan. Komponen pembelajarannya, yaitu; 1) online learning, 2) pembelajaran tatap muka, dan 3) belajar mandiri. Pembelajaran matematika ke depan,  mengarah ke penggunaan model blended learning. Bahan ajar sebagai sumber belajar perlu disesuaikan dengan kondisi mahasiswa dan strategi pembelajaran yang digunakan oleh dosen. Sangat perlu dikembangkan E-Modul matematika terapan untuk blended learning yang sesuai dengan prinsip-prinsip instruksional. Penelitian ini bertujuan untuk mengetahui tingkat validitas  dan praktikalitas E-Modul matematika terapan untuk model blended learning. Penelitian  menggunakan metode pengembangan model 4D meliputi: Define, Design, Develop, dan Disseminate, dilaksanakan di Politeknik Negeri Bali (PNB).  Subjeknya: ahli isi, ahli media, ahli desain, praktisi dan mahasiswa.  Data validitas bersumber dari ahli isi, media, dan desain dikumpulkan memalui angket validasi. Data praktikalitas bersumber dari dosen pengajar matematika dan mahasiswa dikumpulkan melalui angket validasi dan  praktikalitas. Validitasnya dilihat dari  kelayakan: isi, penyajian, kebahasaan dan kegrafikan. Sedangkan praktikalitas dilihat dari kemudahan penggunaan, kemenarikan sajian dan manfaat.  Data dianalisis secara deskriptif, hasilnya  menunjukkan tingkat validitas mencapai 84,5 % terkategori valid sedangkan praktikalitasnya sebesar 83,6 % terkategori praktis. E-Modul layak dan praktis digunakan untuk blended learing, namun perlu dilakukan revisi-revisi kecil. Implikasinya E-Modul  setelah dilakukan revisi kecil dapat dilanjutkan ketahap pengembangan selanjutnya yaitu uji keefektivan dan desiminasi

Abstract

This study aims to determine the feasibility and practicality of the design of blended learning applied mathematics for vocational education. Research using the 4D model development method from Thiagarajan includes: Define, Design, Develop, and Disseminate, carried out in stages at the Bali State Polytechnic. Currently the Develop stage is being carried out. Data were collected using a validation sheet and a questionnaire for the responses of lecturers and students. Data were analyzed descriptively. The results, 1) the content validity and constructs of blended learning applied mathematics 3,8 and 3,6 are categorized as very valid with a reliability of 88.6% and 91.1% are categorized as very reliable, and 2) the level of practicality by lecturers and students respectively also 83.5% and 83.5% in the practical category. The implication, draft II of this design is very feasible and practical to be used as a learning strategy in vocational education. Draft II can be continued to the next stage of development, namely testing the effectiveness, evaluation and dissemination, but for optimization it is necessary to revise a small receipt referring to the practicality test results.

Abstract

This study aims to determine the level of validity and practicality of teaching materials in the form of textbooks and digital student activity sheets (SAS) applied mathematics for blended learning models. Research using the 4D model development method includes: Define, Design, Develop, and Disseminate, carried out at the Politeknik Negeri Bali (PNB). The validity of textbooks and SAS is seen from the feasibility of: content, presentation, language and graphics. While practicality is seen from the ease of use, attractiveness of offerings and benefits. Data were collected through validation and practicality questionnaires, then analyzed descriptively. The results showed the level of validity of textbooks and SAS reached 83.1% and 83.7% were categorized as valid, while the practicality level reached 83.4% and 82.9% were valid categories. Applied mathematics digital teaching materials are suitable for blended learning, but small revisions are needed. The implication is that Draft II of applied mathematics digital teaching materials, its development after minor revisions can be continued to the effectiveness test, evaluation and dissemination stages.

Abstract

The purpose of the research is to describe the need for developing teaching materials in the form of textbooks and student activity sheets (SAS) based on applied mathematics, and 2) get a draft of textbooks and LKM, applied mathematics based on blended learning. Its development uses the Thiagarajan 4-D model. At present the define, design and part of the develop stage are being carried out. Implementation in the field of engineering of the Bali State Polytechnic. Data were collected using survey methods, documents and questionnaires and analyzed using descriptive statistics. The results of the analysis found that there were 13 mathematics learning achievements and 51 sub-achievements. Student characteristics: 1) attitude toward mathematics is very positive, interest in learning is moderate, 2) motivation for learning is high; 4) high learning independence, 5) 79.7% had difficulty understanding sub textbooks given by lecturers, 6) 89.6% needed alternative teaching materials to understand mathematical concepts, and 7) 83.3% agreed to develop mathematical teaching materials Applied blended learning based uses a problem solving approach. The draft of applied mathematics teaching materials based on blended learning, the material was developed referring to learning achievements, achievement of learning subjects, and sub-achievement of mathematics learning. The main material includes, namely: 1) algebra, 2) geometry; 3) trigonometry; and 4) calculus. The material order, arranged with a hierarchical approach. The four materials are packaged into 2 textbooks and LKM. The teaching material is integrated in the LMS Schoology model. The results of the validator of the draft teaching materials show that teaching materials by making minor revisions, are worth using as materials only

Abstract

The purpose of this study was to determine the effect size of the blended learning design on increasing the Mathematical Problem-Solving Ability of polytechnic education students during the covid 19 pandemic. The study was carried out at the Bali State Polytechnic (BSP), using a mastery-experimental approach, with a pre-test post-test design of non-equivalent control. design groups. The subjects are students in the engineering field of BSP in 2020/2021. Samples were taken purposively as many as 10 classes and divided into experimental and control groups. Data were collected using a mathematical ability test developed by the researcher. The level of validity is between 0.31 and 0.89, the reliability is 0.97, the average difficulty level is 0.41 and the discriminatory power index is between 0.25 to 0.75. Data were analyzed using t test, paired t test and N-Gain score. There is a significant difference between the average mathematical problem solving ability of students taught using the blended learning model and being taught using the full e-learning model. The blended learning model is more effective in improving mathematical problem solving abilities than the full e learning model. The effect size is very large on increasing mathematical solving abilities in learning using blended learning. The implication is that the optimal application of the  blended learning design in polytechnic education during the covid 19 pandemic, the learning process becomes more effective and succeeds in improving students' mathematical problem solving abilities. ​
