Abstract
his study aims to describe the application of the PBL learning model in mathematics learning, to find out the types of errors that students make in solving math story problems based on Newman's analysis, and what factors are the causes of student errors in solving math story problems. The subjects of this research were students of class VII. The type of research used in this research is descriptive qualitative. Data collection techniques used in this research are observation, written tests, and interviews. The results showed that learning with the application of the PBL model with NEA on the rectangular material went very well during the three meetings that went very well, as indicated by the implementation of each of these learning steps during the learning process going well, this indicates that student activities when the learning process by applying the PBL learning model with the NEA went very well. The error analysis based on the NEA shows that the most mistakes made by students were errors in writing the final answer. This was due to students' mistakes in working on the previous stage and also students who did not write conclusions, the lowest error made by students was transformation errors.
Highlights
One of the factors that determine the quality of human resources is education (Yusri, 2018)
Mathematics is a subject that relates to the real world and can be applied in various fields, but learning mathematics in schools is more procedural in nature and requires a lot of practice, many students become inactive in class and only accept lessons delivered by teachers (Li & Schoenfeld, 2019) (Mustaffa et al, 2016)
Based on Newman's Error Analysis (NEA), so that this study aims to describe the application of the Problem Based Learning (PBL)
Summary
One of the factors that determine the quality of human resources is education (Yusri, 2018). As stated by (Yusri, 2018) efforts to improve the quality of education, especially in mathematics learning, are carried out by implementing the 2013 curriculum which is expected to run optimally. According to (Mustaffa et al, 2016), the mathematics literaturer shows that Problem Based Learning (PBL) is a learning approach that can stimulate student thinking. As an effort to overcome student difficulties in solving math problems, teachers can apply the PBL model that can help students to think critically and be actively involved in by linking math problems and everyday life. PBL is learning based on problems, where students will get basic knowledge in the classroom, and be able to apply this basic knowledge to solve problems in everyday life (Bilgin et al, 2009) (Selçuk, 2010)
