This study aims to determine the effectiveness of the Problem-Based Learning model on mathematics learning to instill mathematical literacy in elementary school students. Quasi Experiment was chosen as the type of this research. The research population was the 5th-grade students at SD Muhammadiyah 08 Cilacap, with the research sample consisting of two classes, namely 5A and 5B. The instruments used are test and non-test instruments. Hypothesis testing was carried out using the independent sample t-test and paired sample t-test. The average score on the pretest before the treatment was 59.7 in class 5A and 55.95 in class 5B. The average pretest score in class 5A was 66.6, and 62.15 in class 5B. The post-test average score was 77.7 in class 5A and 91.8 in class 5B. The study results show that the PBL model influences the mathematical literacy of elementary school students and increases students’ learning outcomes.
The Influence of the PBL Model to Improve the Student’s Mathematical Ability of Reasoning and Proof
2018
Effective learning is a learning that affects students' math skills, one of which is the ability of reasoning and proof. The ability of reasoning and proof consists of several stages: Recognize reasoning and proof as fundamental aspects of mathematics; Make and investigate mathematical conjectures; Develop and evaluate mathematical arguments and proofs; Select and use various types of reasoning and methods of proof. The purpose of this research is to know: (1) Is there any influence of PBL model in improving the students' ability mathematical of reasoning and proof in subject of vector analysis course?; (2) Is the PBL model better in improving the students' ability mathematical of reasoning and proof in subject of vector analysis course? This research is a quasi-experiment research. The data analysis technique is done from test stages of data description, prerequisite test is normality test, and hypothesis test using ANCOVA test. The results showed that: (1) There is an ...

The purpose of this study was to determine whether mathematical problem solving abilities of students who get learning using the Brain Based Learning (BBL) approach are higher than students who get conventional learning. This type of research is Quasi experiment. The study population was students in class V SD gugus IV in Padang Utara sub-district. Sample selection is done by purposive sampling. The research sample was fifth grade students of Angkasa I Elementary School, consisting of two classes which were used as experimental class and control class. Research data is taken from test scores. The technique of analyzing research data through t-test. Students' mathematical abilities, especially mathematical problem solving, are still low. This happens because the implementation of learning is still teacher-centered. students tend to be passive and have not had the opportunity to express their opinions. One of the efforts made to improve students' mathematical problem solving ability is by applying the Brain Based Learning approach. An approach that optimizes brain understanding is naturally designed to learn so that learning can optimize diverse brain functions. Learning is carried out in small heterogeneous groups so that students share ideas and negotiate to unite opinions according to learning goals. The results showed that students' mathematical problem-solving abilities who learned using the Brain Based Learning approach were higher than students who learned with conventional approaches. This can be seen from the average value of the experimental class final test (54.99) higher than the average value of the control class (39.44). This is reinforced by the t-test that obtains the Sig. 0.001 < 0.05, is rejected, meaning that BBL has a significant effect on students' mathematical problem solving abilities.

This research is quasi-experiment. The purpose of this research is to know whether students’ mathematical representation by using instruction of problem based learning classroom is higher than direct instruction classroom at SMA Swasta Panca Budi Medan.The population of this research is students of SMA Swasta Panca Budi Medan which consists of 14 classes, whereas the sample consists of 2 classes, namely, X-MS1 as experimental class consists of 32 students and X-MSA as control class consists of 30 students. Experimental class used Problem Based Learning and control class used Direct Instruction. Collecting data technique of this research is mathematical representation test given in the end of learning either in experimental class or control class. The type of this test is essay test. Before doing hypothesis test, the normality and the homogeneity test should be done. The result of those tests, sample was taken from normal distributed and homogeneous population. The data analysis of e...

This paper discusses the effect of the PBL (Problem-Based Learning) learning model on students' math arithmetical skills in integer material in class V of MIS Perdamean Sigambal, Rantauprapat, North Sumatra Province in the academic year 2020/2021. The research uses quantitative research (Quasi Experiment) with the research sample determined by total sampling technique. The population of the research was 30 students, which consists of 15 students in class V-A as the control class and 15 students in class V-B as the experimental class. The results indicate that students' arithmetic skills using the PBL learning model were in the very good category with an average score of 87.2. The hypothesis results that have been carried out indicate tcount 2.658 > ttable, 1.701 at a confidence level of 0.05. Thus, there is a significant effect of applying the PBL (Problem-Based Learning) learning model on students' arithmetical skills in class V of MIS Perdamean Sigambal Rantauprapat and it provides information to teachers in applying the PBL (Problem-Based Learning) learning model to improve students' thinking skills.
