Abstract

Mathematics is mostly related to human life, thus, humans are required to have the mathematical understanding ability in solving life problems since in the elementary school age. Therefore, mathematics learning at school should have relevance value to construct mathematical concept that can be used in real life.  Innovative mathematics learning through Contextual Learning (CTL) model based on Sundanese Culture Ethnomathematics as a local wisdom at which humans use mathematics in their real life, was chosen as a deep solution to increase the mathematical understanding ability, because students live in their culture and society. This study employsan experimental method by conducting pretest and postest control group design. The purpose of this study is to determine the increasing of students’ mathematical understanding ability on experiment class (using CTL model based on Sundanese Ethnomathematics) and control class (using conventional learning model). The result of this study produced conclusion that CTL based on Sundanese ethnomahtematics and conventional model can increasethe mathematical understanding ability significantly. However, the application of CTL model based on Sundanese Ethnomathematics was significantly better than conventional model (62.29%) to increase students’ mathematical understanding ability on learning the basic concepts of rectangular geometry for 4th grade students of elementary school.

Abstract

The Indonesian government has implemented awareness of literacy's importance through the school literacy movement at every level of education. The literacy movement, especially at the elementary school level, is carried out in three stages. There are habituation, development, and learning. The literacy movement's implementation since 2016 at the elementary school level has carried out well. However, there are still some obstacles. The method used is a systematic literature review. It examines various reports of literacy stakeholders in their implementation against each context. These reports found different effective strategies for successfully implementing the literacy movement, which can use as references. It then discovered that various obstacles became the gap in literacy education in Indonesia to be minimized further. This systematic literature review highlights a need to implement meaningful and innovative strategies by utilizing stakeholders such as teachers, school principals, parents, communities, and teacher institutes to provide professional context-based input related to the literacy movement

Abstract

Mathematical proficiency as a goal of learning mathematics and other skills developed by teachers in schools through a didactic and pedagogical activity. The quality of teaching mathematics in elementary education is largely determined by the teacher's perspective on Pedagogical Content Knowledge (PCK) in mathematics learning itself. This study aims to see the perspectives of elementary school teachers who are experienced in teaching mathematics regarding several things that are needed in learning mathematics in elementary schools. The study used a survey method which was conducted on elementary school teachers who have experience in teaching mathematics with various educational backgrounds and different schools (n = 65) through random sampling. The study is focused on investigating the pedagogical perspective, the perspective of mathematics learning objectives, and the perspective of mathematics content taught in elementary schools. These perspectives are arranged in a research instrument in the form of a questionnaire containing multiple answer questions and open-ended answers. Data collection was carried out with the help of google forms. The data analysis used is quantitative and qualitative approaches. The results showed that various innovative learning models were known by the teacher, although not all teachers were sure that they had implemented the learning model according to the syntax of the learning model. Also, teachers are still optimistic that innovative learning models have flexibility so that they can be applied in pandemic conditions.

Abstract

Textbooks are still used as the main learning resource used by teachers in school. The book must provide content that is very supportive in helping students to achieve understanding related to a topic. This study aims to analyze how decimal material is studied in mathematics textbooks published by the Ministry of Education and Culture of the Republic of Indonesia. The analysis focuses on the content and presentation of math problems available in books. This study uses a qualitative approach with analytical methods. Research findings show that the decimal material focuses more on procedural knowledge than on trying to deepen conceptual understanding. The problems in the book are dominated by problems that only reveal procedural knowledge. There are no questions that reveal representation skill, reasoning, and conceptual understanding. Based on this research, it appears that teachers should make more efforts to find learning resources that more supportive of success in learning mathematics. Because the success of learning mathematics can be seen from the development of mathematical proficiency, not only in computational or numerical skills.

Abstract

Changes in the education system due to COVID-19 pandemic through distance learning (PJJ) have made it difficult to accommodate students’ needs in achieving mathematical proficiency. The needs of these students are based on students learning style preference (KGB), how students obtain information, as one of the determinants of success in learning mathematics. This study aims to investigate the extent to which each student’s KGB can adapt to the PJJ designed through RADEC (Read-Answer-Discuss-Explain-Create) and direct learning. A quasi-experimental study with 2 x 3 factorial designed was conducted involving 56 4th graders from a private elementary school in Bandung. The research instrument used was the KGB scale and mathematical conceptual understanding (MCU) test. The result of this study showed that there were differences in students’ MCU viewed by KGB during PJJ which was more accommodating to visual students. It is necessary to improve the PJJ design that accommodate each KGB.

Abstract

In the last decade, education systems around the world have prioritized increasing students’ literacy and numeracy skills. The increasing need for language literacy has resulted in the emergence of a trend bilingual program in primary schools. This research was motivated by the learning problems that occurred in the first year bilingual program. The study aims to see the effectiveness of the Content and Language Integrated Learning (CLIL) approach on the competence of sains curriculum content and students' language skills. The research method used was Classroom Action Research (CAR) with the research subject being the first year students of the bilingual program who were stand on grade 4th primary school (n = 21). Data analysis not only focuses on increasing scores in each cycle, but also obtains new findings about the stability between science content abilities (non-language) and second language skills (english). Initial data explains that only 25% of students meet the learning completeness aspect. Along with the end of the third cycle, the study found that 85% of students could complete learning completeness. The study concluded that the CLIL was able to stably improve content and language skills with certain improvement criteria. The findings from the improvement of this cycle can be used as a reference for developing CLIL research in primary schools especially on bilingual programs.

Abstract

Students’ mathematical conceptual understanding (MCU) as major part of mathematical proficiency needs to be developed since elementary school through a didactic-pedagogical activity. One of these proficiency needs to be developed in the learning of perimeter and area of a plane geometry. The reason is students often find difficulties in understanding those concepts, especially in situations of distance learning due to COVID-19 pandemic. This study aims to investigate the achievement and enhancement of students’ MCU through RADEC learning model. This study used quasi-experimental method with non-equivalent pre-test and post-test control group design. Subjects of this research were 56 of 4th graders at one of private school in Bandung, Indonesia. This study found that there are significant differences in the achievement and enhancement of students’ MCU between students who received RADEC learning and direct learning where the RADEC learning model was higher in achieving & enhancing students’ MCU. In addition, the invention of the RADEC learning model on the achievement and enhancement of students’ MCU is in the moderate effect category with the acquisition of Hedges’ g of 0,922 in the level significant effect
