Abstract

The studies on the worked-out examples teaching approach (WOETA) have been investigated globally and in South Africa, showing gains in learners' performance. This study reports on the Euclidean geometry short learning programme (EGSLP), which used worked-out examples teaching approach (WOETA) intervention to secondary mathematics teachers enrolled in one university campus in the Free State province. This study used one group pretest-posttest research design.65 participants completed the pre-test, participated in WOETA, and later completed the post-test. The WOETA engaged the participants in the Euclidean geometry six topics, straight-line geometry, classification of triangles, Pythagoras, similarity and congruency, properties of polygons, and measurement that helped them to acquire procedural and conceptual knowledge. The findings revealed that the WOETA improved the participants' performance in two topics, straight-line geometry and classification of triangles. In contrast, it failed in four topics Pythagoras, similarity and congruency, properties of polygons, and measurement. Cronbach alpha was used to calculate the reliability of the pre-test and was 0,52, while the post-test reliability was 0.30, and these values were deemed not acceptable and not reliable. The findings also revealed that the WOETA does not affect participants' Euclidean geometry performance.

Abstract

The activeness of students is important and fundamental to support the effectiveness of online mathematics learning. However, the reality shows that students often lack courage and enthusiastism in asking and answering questions, conveying understanding, and being less involved in doing assignments. Some of these indicate that students are less active in learning mathematics online. One of the efforts that teachers can make is through the application of various interactive media. Therefore, this paper aims to review and examine the implementation of various interactive media as an effort to stimulate the activeness of the students in online mathematics learning. Using descriptive qualitative research methods, it is evident that the implementation of various interactive media can enourage students to be active in online mathematics learning. The implementation of  various interactive media make students pay attention, so they can be encouraged to be actively involved in the learning process. Thus, students can be led to maximaze themselves in every opportunity to glorify God, including in the mathematics learning process. In the application of interactive media, teachers are advised to record every development of student responses for the improvement and development of interactive media.BAHASA INDONESIA ABSTRACT: Keaktifan siswa menjadi hal penting dan mendasar yang dapat menunjang keefektifan pembelajaran matematika secara daring. Namun, kenyataan menunjukkan bahwa siswa sering kurang berani dan antusias dalam bertanya, menjawab, menyampaikan pemahaman, serta kurang terlibat dalam mengerjakan tugas. Beberapa hal tersebut menunjukkan bahwa siswa kurang aktif dalam pembelajaran matematika secara daring. Salah satu upaya yang dapat dilakukan guru dalam mendorong keaktifan siswa adalah melalui penerapan media interaktif yang bervariasi. Olehnya tulisan ini bertujuan meninjau dan mengkaji penerapan media interaktif sebagai upaya yang dapat menstimulus keaktifan siswa pada pembelajaran matematika secara daring. Melalui metode kualitatif deskriptif, diketahui bahwa penerapan media interaktif yang bervariasi dapat mendorong siswa menjadi aktif dalam pembelajaran matematika secara daring. Media interaktif yang bervariasi menarik perhatian siswa sehingga mendorong siswa terlibat aktif dalam pembelajaran. Dengan demikian, siswa dapat dituntun untuk memaksimalkan diri dalam setiap kesempatan untuk memuliakan Allah, termasuk dalam pembelajaran matematika. Dalam penerapan media interaktif, guru disarankan mencatat setiap perkembangan respon siswa guna perbaikan dan pengembangan media interaktif.

Abstract

The ability of mathematical representation is needed by students to communicate mathematical ideas. However, the student's representation ability is still not optimal, especially in geometry material. The purpose of this study is to describe the representational abilities of students of SMP NU Sunan Ampel in solving geometrical contextual problems. The study was conducted on 19 students at SMP NU Sunan Ampel Poncokusumo. Data was collected through tests and interviews. The indicators of representation ability used are visual representation, symbolic, and verbal. The results of the research are the level of student representation ability as much as 53% in the low category, as much as 42% in the medium category, and as much as 5% in the high category. Students with high representation ability can fulfill the indicators of visual, symbolic, and verbal representation well according to their abilities. Students with moderate representational abilities can meet the indicators of symbolic representation, but there are still errors in writing and calculations. Students with low representation ability have not reached the three indicators of representational ability well as a whole according to their abilities. It is hoped that the teacher can provide practice questions to students by requiring students to describe and write down the mathematical model in detail and completely. In addition, the teacher can also introduce various forms of flat shapes in contextual problems so that students can be trained to solve contextual problems related to flat shapes.BAHASA INDONESIA ABSTRACT: Kemampuan representasi matematika sangatlah dibutuhkan oleh siswa untuk mengkomunikasikan ide matematika.

Abstract

Transparency is an attitude of life that can be used as a role model for others.  The role of the teacher as a role model in the classroom can be implemented through ways of speaking and behaving with students. Therefore, to be a role model for students, a teacher must have good personality competencies. However, as the author experienced, Practice Field Experience Christian teachers are not yet capable of having good personality competencies. This is because they have not been able to control and manage emotions when faced with problems that occur in teaching online. In addition to explaining the personality competence of Christian teachers, the writing of this article aims to outline the efforts of the author, as a Christian teacher, in improving personality competencies to become a role model for students. The research method used is qualitative descriptive. This method is done by revealing facts, phenomena, variables, and circumstances that occur during the research. The results of the research are described based on real situations.  Based on the results of this research, it can be concluded that to improve the personality competence of a Christian teacher, there needs to be an effort to deepen the personal relationship with God through understanding the Word of God. If a Christian teacher has improved personality competence by learning the Word of God, then a Christian teacher in practice will be a role model for students.BAHASA INDONESIA ABSTRACT: Keteladanan adalah sikap hidup yang dapat dijadikan panutan bagi orang lain. Peran guru sebagai seorang teladan di dalam kelas harus diimplementasikan melalui cara berbicara dan bersikap yang baik dengan siswa. Oleh karena itu, untuk menjadi teladan bagi siswa seorang guru harus memiliki kompetensi kepribadian yang baik. Pada kenyataannya, ketika Praktek Pengalaman Lapangan 2 penulis sebagai seorang guru Kristen belum cakap memiliki kompetensi kepribadian yang baik. Hal ini dikarenakan penulis sebagai seorang guru Kristen belum dapat mengontrol dan mengelola emosi ketika dihadapkan dengan suatu masalah yang terjadi dalam mengajar secara online. Selain menjelaskan kompetensi kepribadian guru Kristen, penulisan artikel ini bertujuan untuk menguraikan upaya penulis sebagai seorang guru kristen dalam memperbaiki kompetensi kepribadian untuk menjadi teladan bagi murid. Adapun metode penelitian yang digunakan dalam penelitian ini adalah metode deskriptif kualitatif. Metode ini dilakukan dengan mengungkapkan fakta, fenomena, variabel dan keadaan yang terjadi saat penelitian berlangsung. Hasil penelitian kemudian dideskripsikan berdasarkan situasi nyata.  Berdasarkan hasil penelitian, dapat disimpulkan bahwa untuk memperbaiki kompetensi kepribadian guru Kristen perlu adanya upaya memperdalam hubungan pribadi dengan Tuhan melalui pemahaman akan Firman Tuhan. Jika seorang guru Kristen sudah memperbaiki kompetensi kepribadian dengan belajar Firman Tuhan, maka seorang guru Kristen dalam prakteknya akan menjadi panutan bagi siswa.
