Abstract

School closures due to the COVID-19 pandemic has resulted in learning loss in primary students, so a diagnosis of the students' numeracy skills is urgently needed at the beginning of learning to adapt learning to students' average ability levels (teaching at the right levels). This study aims to develop a module that can assist and become a reference for teachers in schools in diagnosing and mapping students' numeracy abilities at the beginning of learning. This research was carried out following the procedures for research and development (R&D). The developed module was validated by two experts (media and material experts) prior to implementation with the validation results being in very good categories for each aspect of the material, layout, and graphics. The results of the study based on the teacher's response questionnaire indicated that the module developed is very helpful for the teachers in mapping students' numeracy abilities at the beginning of learning after the COVID-19 pandemic, and it provides an alternative follow-up to the results of students' numeracy assessments. Thus, the developed module is suitable for use as a reference in conducting assessments regarding early primary school students’ numeracy skills.

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: Geometry learning requires teaching materials that are appropriate for the stage of cognitive development. The geometry material has not yet been linked to local culture, resulting in suboptimal understanding of concepts among students. One of the approaches taken is to develop ethnomathematics-based Student Worksheets (LKPD) following the stages of geometric thinking according to Van Hiele's theory, so that the learning is easy to understand. This research aims to develop elementary school geometry LKPD based on Padaw Tuju Dulung ethnomathematics according to Van Hiele's learning theory. The method used is Research and Development with a 4D development model. Research data were obtained thru expert validation sheets and student response questionnaires, then analyzed descriptively qualitatively supported by quantitative data. The research results show that the developed LKPD meets the very feasible criteria with a material expert assessment of 88.46% and a media expert assessment of 90.21%. Student responses indicate a very interesting level of 86.36%. The developed LKPD contains elements of Padaw Tuju Dulung culture and is structured according to the Van Hiele geometric thinking stages, making it suitable for use in geometry learning in elementary schools
