Abstract

Pembelajaran yang kondusif dan menyenangkan dalam revolusi industri 4.0 membuat perubahan dalam gaya belajar dalam proses pembelajaran. Guru dituntut untuk mengikuti proses pembelajaran digital interaktif. Sehingga salah satu tantangan bagi guru dan pengembang teknologi pembelajaran untuk berinovasi adalah menciptakan pembelajaran yang menyenangkan dan tidak membosankan bagi siswa. Pelatihan penyusunan bahan ajar berbasis Web bagi guru matematika bertujuan untuk meningkatkan keterampilan dan pengetahuan guru dalam mengembangkan bahan ajar berbasis web yang sesuai dengn kurikulum dan kebutuhan siswa. Pelatihan ini dilakukan melalui metode peer-teaching model pembelajaran interaktif, Menyusun bahan belajar, Mengemas menjadi bahan belajar on-line. Hasil yang diperoleh setelah melaksanakan kegiatan ini yaitu terdapat peningkatan kemampuan teknologi guru dalam menyusun bahan ajar berbasis web sebagian besar guru matematika SMP di kabupaten Pandeglang menyatakan bahwa hanya kadang-kadang dalam menggunakan teknologi dalam pembelajaran, mereka hanya kadang-kadang menggunakan bahan ajar berbasis Web, namun 80% sudah pernah menggunakan bahan ajar berbasis Web. Tapi tidak satupun dari mereka yang pernah mendesain game pembelajaran matematika di Web. Peserta pelatihan ada yang pernah menggunakan canva dan heyzine, Capcut, dan PPT di WPS HP sedangkan menggunakan game pembelajaran berbasis Web 80% yang tidak pernah menggunakan dan hanya 20% yang sudah pernah menggunakan. Respon peserta pelatihan terkait pelaksanaan kegiatan pelatihan ini menunjukkan bahwa 90% guru menyatakan materi yang disampaiakan sangat menarik (10% menarik) dan semua peserta menyatakan bahwa kegiatan pelatihan ini dapat meningkatkan keterampilan penggunaan teknologi dalam pembelajaran dan membantu untuk meningkatkan profesionalisme guru. Conducive and enjoyable learning in the industrial revolution 4.0 makes changes in learning styles in the learning process. Teachers are required to follow the interactive digital learning process. So one of the challenges for teachers and learning technology developers to innovate is to create learning that is fun and not boring for students. Training on preparing Web-based teaching materials for mathematics teachers aims to improve teachers' skills and knowledge in developing web-based teaching materials that suit the curriculum and student needs. This training is carried out through peer-teaching methods, interactive learning models, compiling learning materials, packaging them into on-line learning materials. The results obtained after carrying out this activity were that there was an increase in teachers' technological abilities in compiling web-based teaching materials. Most of the junior high school mathematics teachers in Pandeglang district stated that they only sometimes used technology in learning, they only sometimes used Web-based teaching materials, However, 80% have used Web-based teaching materials. But none of them had ever designed a math learning game on the Web. Some of the training participants have used Canva and Heyzine, Capcut, and PPT on WPS HP, while 80% have never used Web-based learning games and only 20% have used them. Responses from training participants regarding the implementation of this training activity showed that 90% of teachers stated that the material presented was very interesting (10% interesting) and all participants stated that this training activity could improve skills in using technology in learning and help to increase teacher professionalism.

Abstract

Mathematics learning in vocational high schools is still teacher-centred and relies on structured exercises, leaving little room for students to develop a conceptual understanding. The open-ended approach can be a solution because it allows students to explore various strategies for solving mathematical problems in depth. However, its implementation in vocational high schools remains limited. This study aimed to examine the effectiveness of the open-ended approach in improving the mathematical understanding of vocational high school students. A quasi-experimental design with a pretest-posttest control group design was used. The sample consisted of 72 students in the 11th-grade of Computer and Network Engineering, selected based on previously formed classes. Data were obtained through a mathematical understanding test that measured students' ability to identify, use, and apply the concepts of sequences and series to solve everyday problems. The test instrument consisted of three essay questions, with a maximum score of four for each item. As the data were not normally distributed, the Mann-Whitney U test analysis was used. The results showed that the increase in mathematical understanding of the group of students who received the open-ended approach was significantly better than that of the group who received direct learning.

Abstract

This study aims to evaluate the extent to which the open-ended approach affects the achievement of students' mathematical understanding ability in vocational high schools (SMK). The method used was a quasi-experiment with a pretest-posttest control group design, in which two groups of students (experimental group and control group) were compared based on test results before and after treatment. The research sample consisted of 72 students who were selected by intact group (based on the class that had been formed) to minimize disruption to teaching and learning activities at school. This sampling was done by considering the real conditions in the field so as not to disrupt the existing learning schedule and class structure. The research data was obtained through a description test consisting of three questions, with a maximum score of 12 for each question. Data analysis was conducted in two stages: first, a normality test to check data distribution, and second, a mean difference test using the Mann-Whitney U test because the data were not normally distributed. The results showed that the group of students taught with the open-ended approach had better mathematical understanding achievement than the group that received direct learning. This finding indicates that the open-ended approach is effective in promoting mathematical conceptual understanding through independent exploration.
