Abstract

Mathematical thinking is necessary in mathematics learning especially in college level. One of activities in undergraduate mathematics learning is proving. This article describes students' thinking process who unable to construct mathematical formal proof. The description uses APOS Theory to explore students' mental mechanism and students' mental structure while they do proving. This research is qualitative research that conducted on students majored in mathematics education in public university in Banten province, Indonesia. Data was obtained through asking students to solve proving-task using think-aloud and then following by interview based task. Results show that the students could not construct a formal proof because they unable to appear encapsulation process. They merely enable to think interiorization and coordination. Based on the results, some suitable learning activities should designed to support the construction of these mental mechanism.

Abstract

Abstrak. Matematika merupakan salah satu ilmu yang wajib dipelajari oleh semua kalangan, baik dari jenjang SD maupun Perguruan Tinggi. Namun, untuk menilai suatu pembelajaran, seperti matematika, diperlukan asesmen atau bentuk penilaian yang baik. Hal ini diharapkan agar semua aspek dapat terlihat dan terukur kecapaiannya. Maka dari itu penelitian ini akan mengkaji asesmen kinerja atau (Performance Assessment) menggunakan systematic literature review dimana peneliti mengkaji beberapa artikel dari tahun 2013-2022 dan mengambil kesimpulan dari studi literatur tersebut. Dari 163 artikel atau studi literatur yang diperoleh, hanya 18 yang akan diolah setelah melakukan langkah-langkah oleh Transfield (Tranfield et al., 2003). Pada kesimpulannya, diperoleh bahwa asesmen kinerja dapat dengan efektif berpengaruh dalam pembelajaran matematika.Kata Kunci: Penilaian Kinerja, Langkah Tansfield, Matematika
