Abstract

The purpose of this research is to identify the learning obstacles experienced by students at Nurul Huda Jannatun Vocational High School. This study is a qualitative research that uses the Didactical Design Research (DDR) model. The population of the study consists of 32 students from the 11th grade of Nurul Huda Jannatun Vocational High School, while the sample is taken from 3 students using purposive sampling method. The research findings reveal the following student obstacles: lack of readiness to receive learning due to a lack of motivation in learning, lack of knowledge of formulas to solve problems, misinterpretation of problems leading to errors in calculations, lack of understanding of the concepts presented in the given problems, inability to answer questions involving two transformation concepts, inability to answer story problems, perception of teachers explaining the material too quickly and lacking easily understandable illustrations, and inadequate teaching materials that do not explain the material in detail for each part

Abstract

Learning about the concept and structure of a mathematical material and looking for relationships between them is real math learning. In many math learning materials, students often struggle to understand the concept of the material. The mathematical skills need to be stimulus and encouraged when learning. To practice such skills need innovations such as using motion graphics learning media. The purpose of this research is to know the student's response to the use of motion graphic media, to find out how much the mathematical skills of students after using motion graphic learning media, to know how much influence The media use of motion graphic learning to the students mathematical skills, to determine the effectiveness of the use of motion graphic learning media to the students mathematical skills. This method of research is experimental research with data collection techniques using poll and observation for variable X and test for variable Y. Population for this research is all students of grade IX SMP IT Umar Al Khattab Gunung Jati Kabupaten Cirebon, while the sample Taken by the cluster method of random sampling with the elected class IX B SMP IT Umar Al Khattab Gunung Jati Kabupaten Cirebon. Based on the results of the data processing, the student response questionnaire was obtained against the use of media in motion graphic media learning with an average of 85.23% with very strong criteria. Based on the hypothesis test result obtained tcount > ttable = 9,895 > 2.063, then H0 rejected or Ha is acceptable, the use of Motion graphics Learning Media is effective against the mathematical understanding of grade IX students SMP IT Umar Al Khattab. It is also supported through an N-Gain value of 65.40 as well as an indicator of the learning effectiveness of a KKM pass of 91.66% classifying, student response 85.23%, student activity of 77,,33%, as well as the ability of the teacher to manage the class that got the value 3.34.
