PENGENALAN ANGKA ANAK MELALUI MEDIA BALOK WARNA DI RA NURUL UMMAH

This study aims to determine the implementation of the introduction of children's numbers through beam media at RA Nurul Ummah Kenep Balen, Bojonegoro Regency. This study uses a qualitative approach. Data was collected by using interview, observation, and documentation techniques. Data analysis techniques include the method of induction and descriptive/interpretive analysis, data presentation, and conclusion drawing, checking the validity of the research by extending the participation of researchers, triangulation techniques. The results showed that the introduction of children's numbers through the media of color blocks can increase the knowledge of numbers for children, and for teachers it is easier for students to understand numbers. The supporting factors are the existence of a program that has become a mandatory activity set by the school as one of the subjects, the support from the school to provide educational learning facilities in the form of color blocks, the ability of active and creative teachers to use media facilities, while the inhibiting factors are students who still cannot distinguish the color of the blocks, students are late when entering. Efforts to recognize numbers that need to be done are careful preparation for teachers before doing learning, both learning administration, teaching preparation, and learning media, especially in counting using color block media, and the presence of complementary media from color block media.

The Influence of Playing with Number Blocks on the Increase in Counting Ability in Class 4 Mental Retardation Children in SDLB/C Aditama Surabaya

Background: The number block is a media that Montessori created in 1909. This block media is made of a wooden square and consists of 10 blocks with red and blue colors. Each red and blue segment represents the sum of 1 block. According to Fridani in Kompas Daily (2010), the block game itself has several advantages, including that children can recognize mathematical concepts because by playing blocks, children get to know more concepts - less, the same and not the same, the concepts of numbers and numbers and science. Such as calculating, classification, gravity, and stabilization.Objective: To determine the effect of number blocks on increasing numeracy skills in mentally disabled childrenMethod: The research design was a pre-experimental design with one group pre-test - a post-test design approachResults: Before being given the intervention to play numeric blocks, most of the ten respondents (59%) had the level of numeracy (analyzing number symbols, addition, and subtraction) in children with mental retardation, which was in the low category. Mental is in the good category for eight respondents (47%), and five respondents (29%) are included in the good category.Conclusion: There is an effect of numeracy skills on children with mental retardation before and after the intervention to play number blocks.

The criterion of block media strength and geomechanical back-calculation

Relevance and problematics. The mechanism of block medium and jointed rock mass deformation and breaking differs notably from continuum mechanics ideas, making up the crucial fundamental problem of geomechanics and distinguishing it from other engineering sciences connected with the mechanics ISSN 0536-1028 «Известия вузов. Горный журнал», № 6, 2020 47 of deformable solids. However, due to poor understanding of block media breaking mechanism, rock masses strength is overwhelmingly estimated by means of empirical dependences obtained by simulation in laboratory conditions. It is apparent that this approach does not solve the crucial fundamental problem and the accuracy of predicting mechanical characteristics of jointed rock masses may reach 100%. Research methodology. Based on the earlier theoretical research by the methods of variational, integral, and differential calculus, a new mechanism of block mass breaking at a point was substantiated. It implies translation and rotational character of blocks displacement in a rock mass in the process of its deformation making it possible to substantiate the criterion of jointed rock masses breaking. Research results, analysis and recommendations for use. The research was the first to obtain the block medium strength criterion. It has been shown that block mass strength is made up of the strength along the slip joint and block rotation resistance. Besides, within some range of loads, the ultimate strength of the rock mass is proportional to the tensile strength of a structure block. The work also proposes a range of analytical dependences obtained based on the solid mechanics making which make it possible to back calculate the rock mass strength based on the curvature of the shear rupture surface and assess the full tensor of the plain field of strain by the base axes orientation.

Efektivitas Alat Peraga Edukatif (APE) Balok Dalam Mengembangkan Kognitif Anak Usia Dini

The effectiveness of the use of teaching aids that are associated with cognitive development of early childhood, with the strategy of applying the method of playing blocks in the Kindergarten Plus Cinangka Sawangan Depok conducted by the teachers will determine the success of the effectiveness of the cognitive development of students, which are then developed routinely in accordance with the learning objectives It has been planned to be associated with the strategy of applying the method of playing blocks in accordance with basic competencies and learning indicators. Learning practices that use block media at TK Permata Plus are less than optimal due to the ratio of learners whose number exceeds the number of available beam props, so learning cannot be maximized. The active involvement of children is needed to improve their abilities and further research is needed from various variations to contribute to the learning problem. Playing with blocks can improve cognitive abilities of early childhood including: recognizing geometric shapes, recognizing colors. Make a Beam shape creation, sort objects based on five size or color seriations and classify objects into the same or similar group or in pairs with two variations.

Pengaruh Penggunaan Media Blok Pecahan Terhadap Minat Belajar Pada Mata Pelajaran Matematika Siswa Kelas III SD Kompleks Lariang Bangi Kecamatan Makassar Kota Makassar

Through this study, the objectives to be achieved are to (1) describe the extent to which: (a) the interest in learning elementary school mathematics through the use of Fraction Block Media, (b) student responses, and (c) implementation using fraction block media (2) see the effectiveness of the use of Block Fraction media, and (3) publication of scientific articles dijurnal national accreditation or international journals. The research design that will be used is a quasi experimental research design with a pretest-posttest control group design. The study population was Class III students at SD Kompeks Lariang Bangi consisting of 3 schools, namely Lariang Bangi 1 Elementary School, Lariang Bangi 2 Elementary School, and Lariang Bangi 3 Elementary School with two classes of samples. The research instruments consisted of (1) Questionnaire Interest in Elementary Students, 2) Student Response Questionnaire, (3) Sheet Observation on the Implementation of Fraction Block Media Usage, and (4) Documentation. Analysis Techniques Data to be used are Analysis of Descriptive and Inferential Data. The Research Results Show That (1) The learning process using Fraction Block media in the experimental class takes place effectively because the percentage categories for each meeting increase. (2) The value of post non test in the experimental class shows that more than 50% of students are in the category of interest. While in the control class more than 50% of students are in the less interested category, (3) The average student response is at an average of 78 with a standard deviation of 5.28 from the ideal score of 100, and (4) There is a positive influence on block media usage Fractions in the learning process.
