“…Therefore, previous research has tested in order to improve learning outcomes with a variety of methods and developments such as using Problem Solving-based discovery learning models and problem solving-based group investigations that have greater results on using the group investigation model (Vahlia & Agustina, 2016), Other researchers have also tested the improvement of learning outcomes in numerical subjects using cooperative jigsaw which resulted in an increase of 23.33% which has an influence on improving learning outcomes (Shoffa & Suprapti, 2017). Other researchers have used numerical methods to examine the symbolizations contained therein as well as representations of concepts and procedures (Mulyatna & Kusumaningtyas, 2017), other researchers developed a constructivist-based numerical method textbook (Khaidir, 2016), other researchers developed instructional materials also for numerical methods based on problem solving (Fadillah, nd), other researchers in conducting research by using student worksheets as learning media for numerical methods courses (Purwati, 2016), other researchers tested numerical methods for the effectiveness of the Ideal Problem Solving learning model (Purnomo, Prasetyo, & Budiharto, 2016), other researchers tested the improvement of student skills Through guided inquiry practicum activities (Rakhmawati & Hartiningrum, 2019), other researchers developed the adaptive learning system using SAW to determine the value of learning (Putra, Wirawan, & Sugihartini, 2018), and other researchers also implemented strategies for applying the JIGSAW learning model (Nawafilah & Masruroh, 2018) from several previous studies, many researchers tested the improvement of learning outcomes on numerical methods. Therefore, the researchers are currently testing how the students' procedural fluency in numerical methods courses.…”
