Abstract

This current research was aimed at analyzing and describing teacher’s scaffolding patterns applied to cooperative learning setting to help students solve mathematical problems. This research was designed qualitatively, recruiting a mathematics teacher of the eighth grade as the subject. Further, the instruments used to carry out the research comprised a test with HOTS questions, observation sheet, and interview guide. To identify the teacher’s scaffolding patterns, the target students were required to work on the HOTS test. Afterwards, they were grouped based on the level of difficulty they faced during working on the test. Next, the teacher provided the students with the scaffolding based on the students’ needs in each of the created groups. This research indicated that the scaffolding given to the group of students with no difficulty in solving the problem only covered a reviewing component. Meanwhile, to the group with the difficulty in executing the plans as arranged, the scaffolding comprised explaining, restructuring, and developing conceptual thinking components. At last, to the group with a sole ability to understand the problem, the whole components of scaffolding were of great necessity, including environmental provisions, explaining, reviewing, restructuring, and developing conceptual thinking.Tujuan dari penelitian ini adalah untuk menganalisis dan mendeskripsikan pola scaffolding guru pada setting pembelajaran kooperatif untuk membantu siswa memecahkan masalah. Penelitian ini adalah penelitian kualitatif dengan subjek guru matematika kelas VIII. Instrumen yang digunakan dalam penelitian ini adalah lembar tes soal HOTS, lembar observasi dan pedoman wawancara. Untuk mengetahui pola scaffolding guru, siswa diminta untuk mengerjakan tes HOTS.

Abstract

The basic objective of the microteaching course is to support the implementation of apprenticeship 3 (teaching practice) in the seventh semester at school. So far, the practice of teaching in the classroom by students is often constrained by the readiness of students in preparing these teaching tools. To overcome these obstacles, it is necessary to design a didactic condition according to the obstacles experienced by students, to be able to guide students in carrying out teaching practices properly. This process requires planning (plan), implementation (do), and reflection (reflection) of learning so that the microteaching learning process is carried out based on lesson study. The purpose of this study was to develop a didactic design in microteaching learning for lesson study-based mathematics teacher candidates. The research method used is qualitative in the form of didactic design research. Based on the implementation of the didactic design of lesson study-based microteaching learning for prospective mathematics teacher students, it is concluded that this didactic design can be used as alternative learning to overcome the learning obstacles experienced by students in microteaching learning.Tujuan dasar dari mata kuliah microteaching adalah untuk mendukung pelaksanaan magang 3 (praktek mengajar) pada semester VII di sekolah.
