Abstract

The objectives of this study are to observe whether : (1)knowing process  implementation of learning by using Student Facilitator and Explaining Model, (2) the improvement of learn mathematic result throughStudent Facilitator and Explaining Model by subject of FPB and KPK. This study was held at SD Negeri 060798 Medan Area Selatan by subject students of grade IV having 22 students. This study used classroom action research. The results showed that there was increase learn mathematic result studentsfrom cycle I to cycle II. Percentage increase learn mathematic result from cycle I to cycle II is 19,72% with average 59,24 increasing becaome 73,87.

Abstract

This study aims to describe and see the effect of implementing Android-based mind mapping learning media on the fighting power and problem-solving abilities of PGSD University Quality Science. This type of research is quasi-experimental research (quasi-experiment). The sample in this study was class 2A11 consisting of 22 people and class 2A12 consisting of 20 people. The research instruments used were tests and observation sheets of fighting power. The data analysis technique used is an independent test between two factors. Based on data analysis and hypothesis testing, it was found that: (1) There was an increase in the fighting power of Quality University PGSD students after the implementation of Android-based mind mapping learning media (2) The ability to solve science in PGSD University Quality students after the implementation of Android-based mind mapping learning media obtained an average value of Average: 81.25 (3) There is a significant effect through the application of Android-based mind mapping learning media on the fighting power and ability to solve science problems in PGSD University Quality students.

Abstract

This study aimed to determine the effectiveness of the Problem-Based Learning (PBL) model assisted by Flashcard media on students’ mathematical literacy and to examine students’ participation in solving problems presented through Flashcard media. The study employed a Pre-Experimental Design with a One Group Pretest-Posttest design. The research subjects were 22 tenth-grade students of the Building Modeling and Information Design (DPIB) program at SMK Negeri 5 Medan. The research instruments consisted of an essay test to measure mathematical literacy and an observation rubric to assess student participation, both of which had been validated. The results showed that the average mathematical literacy score increased from 71.82 in the pretest to 80.23 in the posttest. The hypothesis test yielded t-count > t-table, or 16.54 > 2.079, indicating the effectiveness of the Problem-Based Learning model assisted by Flashcard media on students’ mathematical literacy. The observation results showed an average student participation score of 3.46, categorized as very active, with the highest score in the cooperation aspect at 3.60. Thus, the implementation of PBL assisted by Flashcard media can improve mathematical literacy while encouraging active student participation in the learning process.
