Abstract

Understanding concepts is one of the important things in learning Mathematics. However, in reality it was found that Grade 2 students had difficulty in understanding the concept of Mathematics. Therefore, in this study a strategy has chosen, namely Differentiated Instruction. The purpose of this study is to determine whether the application of Differentiated Instruction learning strategy can improve the understanding of the concept of class 2B students on Mathematics. The method carried out is the Classroom Action Research (CAR) by Robert Pelton with two cycles. The research was conducted at a Christian school in the West Jakarta area on September 26 to October 16, 2018, conducted with a total of 7 meetings. The instruments to collect data are lesson plans, mentor feedback, reflection journals, tests and documentation (photos). The results of the study shows that the Differentiated Instruction strategy can improve students' understanding of concepts on the three indicators used in this research. The maximum achievement of each indicator is restating a concept (72%), classifying objects based on certain characteristics according to the concept (100%), and presenting concepts in various forms of representation (80%). Differentiated Instruction can improve the understanding concept of, if each of the strategic steps are implemented properly. However, there are some things that need to be considered such as the emphasis on the concept of clear material, giving clear but simple instructions (for lower grade students), giving clear and firm rules, as well as variations in learning according to interests, learning styles, and student readiness.

Abstract

Competence in the use of Information and Communication Technology (ICT) has become a part that is needed to be mastered by prospective student-teachers. Students are expected to use ICT appropriately in education. The problem that often happens is that many students have difficulty working on tasks outside the classroom, especially when Microsoft Excel. Many students appear to understand and look like they are able follow guided practice in class, but outside of class they are confused and often forget the instructions given by lecturers. One solution for dealing with these problems is to provide learners with a multimedia module for learning how to create and use spreadsheets. It is hoped that this module will help students to solve their learning difficulties in ICT courses including those with different learning styles. The purpose of this research is to evaluate the usefulness of this multimedia module. The development of this module was done by using the ASSURE model which consists of six stages: (1) analyze the learners; (2) state objectives; (3) select appropriate methods, media, and materials; (4) utilize materials; (5) require learners’ participation; and (6) evaluate and revise. The results of the questionnaire indicate that candidate teachers tend to be stronger in learning through Visual-Auditory ways. In addition, student mastery of the Excel Sheet processing program has the lowest value of Word and PowerPoint programs. The design of this learning module will be made by taking into account the Visual-Auditory aspects of the Microsoft Excel topic. This learning module will be developed with an interactive design using the PowerPoint 2016 program. BAHASA INDONESIA ABSTRAK: Kompetensi penggunaan Teknologi Informasi dan Komunikasi (TIK) menjadi bagian yang perlu dikuasai oleh mahasiswa calon guru.

Abstract

Schools are educational institutions that are primarily focused on achieving educational goals. In achieving these goals, schools need competent teachers. Competent teachers are teachers who have four teacher competencies, namely learning management (pedagogical competence), potential development (social competence), academic mastery (professional competence), and personality attitudes (personality competence). A teacher must possess these four teacher competencies in order to support his/her role as an educator. Based on the field experience program conducted by pre-service teachers, it is evident that pre-service teachers lack professional competence. The purpose of writing this paper is to further examine the importance of professional competence for pre-service teachers in supporting the ongoing learning activities at a school, especially for a Christian teacher. The importance of professional competence for a pre-service teacher can provide confidence when teaching, the capacity to guide in mathematics learning activities, and the ability to carry out his/her role as a restoration agent. To improve professional competence, teachers should conduct microteaching activities, study, and attend seminars and other benefical activities.BAHASA INDONESIA ABSTRACT: Sekolah merupakan lembaga pendidikan yang paling utama berfokus kepada pencapaian tujuan-tujuan pendidikan. Dalam mencapai tujuan pendidikan yang telah ditetapkan, sekolah membutuhkan seorang guru yang berkompeten. Guru yang berkompeten adalah guru yang memiliki empat kompetensi guru yaitu pengelolaan pembelajaran (kompetensi pedagogi), pengembangan potensi (kompetensi sosial), penguasaan akademik (kompetensi profesional), dan sikap kepribadian (kompetensi kepribadian). Keempat kompetensi guru tersebut haruslah dimiliki oleh seorang guru agar dapat mendukung perannya sebagai seorang pendidik. Berdasarkan program pengalaman lapangan yang telah dilakukan oleh mahasiswa calon guru, dapat dilihat bahwa mahasiswa calon guru masih kurang dalam kompetensi profesional. Tujuan penulisan paper ini untuk mengkaji tentang pentingnya kompetensi profesional bagi seorang mahasiswa calon guru dalam mendukung kegiatan pembelajaran yang sedang berlangsung di sekolah, terutama dalam diri seorang guru Kristen. Pentingnya kompetensi profesional bagi seorang mahasiswa calon guru, yaitu memberikan rasa percaya diri ketika mengajar, guru dapat menjadi penuntun dalam kegiatan pembelajaran matematika, serta guru dapat menjalankan perannya sebagai agen restorasi. Dalam meningkatkan kompetensi profesional, guru disarankan untuk dapat melakukan kegiatan microteaching, belajar, mengikuti seminar dan kegiatan-kegiatan yang dapat meningkatkan kompetensi tersebut.

Abstract

This research is based on problems found during the Field Experience Program (PPL 2) when more than 50% of the students scored below the minimal completeness criteria (KKM) on the first daily test and some students were impolite to the teacher.  The author sees these problems being caused by the teacher's lack of ability to manage the classroom, especially in the realm of classroom interaction. One of the expected competencies of a teacher is that he or she is able to become a reflective person. Indeed, God condemns the attitude of a person who always defends himself because it makes him always justify his actions without wanting to reflect upon those actions. Being a reflective person will help a teacher examine his strengths and weaknesses in teaching to improve the quality of his teaching. The purpose of this study is to describe the importance of repeated reflection by a teacher through the reflective thinking process in mathematics learning. The results of the reflection process can help a teacher solve problems in class. The author suggests that the teacher focuses on observing the characteristics of the students in class so that, through the introduction of each individual student, the teacher can prepare what is needed to carry out learning in accordance with the characteristics of students.BAHASA INDONESIA ABSTRAK: Penelitian ini didasari oleh permasalahan yang ditemukan saat menjalankan Program Pengalaman Lapangan (PPL) 2 yang mana pada saat ulangan harian pertama terdapat lebih dari 50% siswa mendapat nilai dibawah KKM dan beberapa siswa yang berlaku tidak sopan kepada guru. Penulis melihat permasalahan ini disebabkan oleh kurangnya kemampuan guru dalam memanajemen kelas khususnya dalam ranah interaksi di dalam kelas. Salah satu kompetensi yang diharapkan adalah guru mampu menjadi pribadi yang reflektif. Sejatinya, Allah mengutuk sikap orang-orang yang selalu membela diri karena hal tersebut akan membuat manusia selalu membenarkan tindakannya tanpa mau merefleksikan tindakannya. Menjadi pribadi yang reflektif, akan membantu guru untuk memeriksa kelebihan dan kekurangannya dalam mengajar untuk memperbaiki kualitas pengajarannya. Tujuan dari penelitian ini untuk mendeskripsikan pentingnya melakukan refleksi berulangkali oleh guru melalui proses berpikir reflektif dalam pembelajaran matematika. Dengan demikian, dari hasil proses refleksi tersebut dapat membantu guru untuk menyelesaikan permasalahan yang ada di kelas. Penulis menyarankan untuk guru fokus mengobservasi karakteristik siswa dalam satu kelas. Supaya, melalui pengenalan akan setiap pribadi siswa, guru dapat mempersiapkan hal apa saja yang dibutuhkan untuk melaksanakan pembelajaran yang sesuai dengan karakteristik siswa.

Abstract

AbstrakMasih terdapat konsep pada Geometri yaitu bangun ruang yang masih kurang dipahami oleh mahasiswa PGSD. Untuk memecahkan permasalahan tersebut, maka dosen menerapkan model pembelajaran yang mendorong mahasiswa untuk dapat mempelajari bangun ruang dengan efektif. Salah satu model pembelajaran yang dapat digunakan adalah Model PACE. Model PACE memiliki empat langkah yaitu Project, Activity, Cooperative dan Experience. Melalui empat tahapan ini mahasiswa dituntut untuk membuat suatu proyek pembelajaran yaitu membuat video pembelajaran. Metode yang digunakan adalah deskriptif dengan sampel penelitian 90 mahasiswa yang dibagi menjadi 2 kelas. Hasil dari penerapan model PACE adalah mahasiswa dapat membuat alat peraga matematika yang menarik. Selain itu penggunaan model PACE juga dapat membantu mahasiswa dalam menghadapi tantangan sebagai guru SD yang kreatif khususnya dalam mengajar Geometri materi bangun ruang. Hal yang perlu diperhatikan adalah dosen sebagai pendidik perlu mendukung agar tahapan yang terdapat pada model PACE dapat terlaksana dengan baik. Using the PACE Model in Geometry Learning Build Space Topic AbstractThere is still a concept in geometry, namely the shape of a space that is still poorly understood by PGSD students. To solve this problem, the lecturer applies a learning model that encourages students to be able to study building space effectively. One of the learning models that can be used is the PACE Model. The PACE model has four steps, namely Project, Activity, Cooperative, and Experience. Through these four stages, students are required to make a learning project, namely making learning videos. The method used is descriptive with a research sample of 90 students divided into 2 classes. The result of applying the PACE model is that students can make interesting mathematics teaching aids. Besides, the use of the PACE model can also help students face challenges as creative elementary teachers, especially in teaching geometry in building materials. The thing to note is that lecturers as educators need to support so that the stages contained in the PACE model can be carried out well.
