Development of LKPD on Fractional Numbers Based on Problem Based Learning in Class IV SDN 07 Silaut

Abstrak

This study uses a 4D development model (define, design, develop, disseminate). Thiagarajan (in Sugiyono 2019:37-38) that research and development steps can be abbreviated as 4D, which can be described as define (definition), design (planning), development (development), and dissemination (dissemination). The research that will be carried out is only up to the development stage due to limited manpower, cost, time, thought and ability. The first stage is the definition stage, at this stage the determination of learning is carried out by analyzing the current curriculum, the current curriculum at SDN 07 Silaut Padang is the 2013 revised 2018 curriculum in the Mathematics subject matter of KD.3.1 fractions. the second stage is the design, at this stage the LKPD based on Problem Based Learning is designed in learning mathematics for class IV. SDN 07 Silaut, Problem Based Learning-based LKPD was created using the Canva application using Times New Roman writing, the size of the LKPD writing used Font 12, for the background using pictures that attract students' interest and is equipped with Problem Based Learning aspects, and also has a working step that will guide students according to the characteristics of elementary school students, the use of writing is clear and can be seen and read by students, then the use of basic background colors is adjusted. The third stage is development, which includes validity, practicality, and validation on LKPD based on Problem Based Learning in class IV mathematics learning at SDN 07 Silaut which was validated by 3 experts from the lecturers of the Faculty of Teacher Training and Education, Bung Hatta University consisting of material experts, linguists, and design experts. Practicality in LKPD based on Problem Based Learning in class IV mathematics learning at SDN 07 Silaut is practiced by educators and students. Based on the results of research on the development of LKPD learning mathematics with fractional numbers, an average overall validity of 83.96% with valid criteria was obtained, while for practicality by teachers and students obtained an overall average of 89.44% with practical criteria. From the results of this study, it can be concluded that the LKPD based on Problem Based Learning mathematics learning material fractions is valid and practical to use in learning mathematics, so it can be used as one of the teaching materials in class IV learning at SDN 07 Silaut.
