Abstract

Understanding the information on the problem presented in the form of pictures is not an easy task for preservice primary teachers to lead to errors. However, preservice primary teachers can also answer correctly if given a mathematical model directly. Preservice primary teachers’ errors can be determined using a process point of view in solving mathematical problems. In a qualitative context, this study describes and analyzes the mistakes of preservice primary teachers traced through errors in solving mathematical literacy problems. This research is qualitative research, where analysis is needed to broaden the understanding of the errors that occur when solving mathematical literacy problems. The results showed that preservice primary teachers experienced errors on each indicator in four types of errors when solving mathematical literacy problems. This research found one new type of error, namely carelessness, which is an error with different types of the four types of errors that exist. Further research can be carried out by designing strategies used to improve the ability of preservice primary teachers to solve mathematical literacy problems.

Abstract

The focus of education during the COVID-19 pandemic is more likely to be cognitive and learning. There has been no maximum effort in strengthening character education. The limited face-to-face meetings in learning have an impact on character education. This situation also applies at the university level. Prospective mathematics teachers who are currently studying have an essential role in building good character education. This study will see how future mathematics teachers' character in producing culture-based learning videos will be seen. The theme in the video that was made was ethnomathematics. The subjects in this study were prospective mathematics teachers who had implemented campus teaching programs and educational internships. With the teaching experience that is owned, it will be seen how the character of the prospective teacher during making learning videos and what character values are contained in the tape so that it can have a positive impact on students. Based on observations during the manufacturing process, most of the prospective teachers have central character values . The results of ethnomathematics-based learning videos are one of the media that can instil character values for students.
