Abstract

The purpose of this research is to produce a learning audiovisual media that is suitable for the material of build a flat side room in SMP Negeri 6 Mataram. The method used in this research is according to Luther, is multimedia development life cycle (MDLC). MDLC have 6 steps, there are concept, design, material collecting, assembly, testing, and distribution. Field testing was used in this research are validation test, practical test, and test for the learning media’s effectiveness. In validation test, the result of this research is validated by some experts. The practical test was carried out by 2 practitioners and the test for effectiveness was based on the results of the questionnaire which were filled in by 74 students (37 students of class VIII and 37 students of grade IX). Instrumen indicators are based on the feasibility of the media according to Thorn. The results of the validation test showed an average score of 3.14, with a very good category. Meanwhile, the results of the practical test with an average score are 3.39 in the very good category, and the results of the effectiveness test with an average score of 2.86 in the good category. So it can be concluded that the audiovisual learning media that have been developed are suitable for use in learning mathematics.

Abstract

This study aims to determine the suitability of cognitive development of class I and II students in understanding the law of conservation of numbers, conservation of material and long conservation with Jean Piaget's theory of cognitive development. This type of research is quantitative with a qualitative-descriptive approach. This study population was 52 students in grades I and II at Madrasah Ibtidaiyah Al-Mukhtariyah Foundation Al-Islamiyah Mamben Daya Academic Year 2020/2021 with a sampling technique using a purposive sampling technique. Based on this technique, 14 research samples were obtained, six samples from class I and eight samples from class II. The instrument used was a test in the form of a brief description of the law of conservation of numbers, conservation of matter and conservation of length. The non-test instrument is an interview combined with a simple experiment. Interviews and simple experiments in this study use coins to the conservation of numbers, water and glass for the conservation of matter, and finally the rope for the conservation of length. Based on the results of the data analysis on the answers to the students' test questions, it is known that 50% of students already understand the law of conservation of numbers, the law of conservation of matter and the law of long conservation. Meanwhile, based on the results of interviews and simple experiments, it is known that 7 students have understood the law of conservation of numbers, conservation of matter and conservation of long, 2 students have understood the law of conservation of numbers and conservation of matter, 2 students have understood the law of conservation of numbers and conservation of length, 2 participants students understand the law of the conservation of numbers and 1 student who does not understand the three conservation laws. For further researchers, they can research the causes of students who have entered the concrete thinking stage and do not understand the law of eternity.

Abstract

The Errors made by students in completed math problems can be indicators of the low learning achievements. Based on these problems, this study aim to know the categories of errors and the relation or correlations of the types of errors each Polya's steps in solving the material story of system two linear equations students all grade VIII of SMP Negeri 13 Mataram academic year 2019/2020. The population in this study was all student grade VIII of SMP Negeri 13 Mataram. Samples used the Proportionate Stratified Random Sampling technique. Data collection used test essai and interview which had beenvalidated. Error categories were analyzed used interval categories of error levels and for the relation or correlations between types of errors used the Pearson product moment correlation. The results showed that students mistakes for high abilities in the low category, for the medium abilities in the high category and for the low ability level in the high category. Based on data analysis it was found three categories relationships types of errors : namely, sufficient, strong and very strong categories. The level of relationship strong enough for this type of error to understand the problem and formulate a plan, misunderstanding the problem and carrying out the plan, misunderstanding the problem and re-checking. Level of strong links to types of mistakes Arranging plans and executing plans, mistakes compiling plans and re-checking. The level relationship very strong for type error implementing the plan by checking again. When completed a problem should be solved systematically in stages to avoid mistakes that will be made at a later stage.
