Articles m The study of continuous learning innovations is carried out on the awareness of the complexity of educational problems. It is a reference that underlies the purpose of this study. With thirty-six students in Class VII from the medium-low cluster education unit in the area, grouped in groups of low to medium and high mathematical abilities based on the ability to understand mathematical prerequisite material, intends to see the relationship between students' positive attitudes which is the impact of innovative treatment imposed, on the ability geometrical understanding achieved by students. With the help of SPSS 17, the findings lead to the conclusion that variations in students 'attitudes towards mathematics and learning are not exactly correct or cannot be explained by the achievement variables of students' geometric understanding abilities in all three groups of mathematical abilities, low moderate and high. There are other variables that influence the achievement of the geometric ability of students in class VII. Because the students' attitude toward mathematics and positive learning is not the dominant variable that does not even have a real effect.

The problem began at the beginning of the emergence of the COVID pandemic 19 in Indonesia, which continued to the necessity of learning as the only possible choice for the implementation of further lecture activities. Researchers view the importance of seeing the effectiveness of the treatment in this case the GC used in the achievement of the objectives of the lecture geometry euclides. The things that researchers pointed out in advance are reasons for researchers to designate research as comparative causal research, along with that involving students' initial ability in the form of a score from quiz 1 that measures the ability of geometric mechanical understanding of schools to the level of C5 thinking ability in bloom taxonomies that researchers have to obtain at the end of the first meeting and the geometric abilities of students obtained based on UTS scores. The analysis of spss17-assisted data was carried out based on the class and the mathematical abilities of the medium and high students of the two classes. From the findings, it was concluded that; Geometric ability of regular class students and non-regular classes after receiving treatment with GC is not different even though the initial ability of the two classes is different based on the quiz 1 score, so learning lectures with the treatment of google classroom can be both used as media and the treatment of geometry courses for regular class and class euclides non-regular in situations and conditions is minimal enough.

Difficulties experienced by students in learning greatly affect the achievement of student learning outcomes. This study aims to describe the results of the identification of the types of difficulties and the causes of student difficulties when solving problems based on Polya stages. This type of research is descriptive qualitative with the instrument used in written tests. The subjects of the research were 36 students of class IX at SMP Negeri 9 Cimahi. Based on the analysis that has been done, it can be concluded that the difficulties experienced by junior high school students when completing the Pythagorean theorem questions in the school are 1) difficulty understanding the problem 100%, 2) difficulty planning the completion of 40%, 3) difficulty implementing the plan 54.4%, and 4) difficulty in re-checking 76.7%. The causes of difficulties include 1) students are not accustomed to writing things that are known and asked of a problem 2) students are not accustomed to drawing conclusions from a mathematical problem 3) Concept errors because students do not understand the concept of the material. So, it is necessary to improve the learning process that prioritizes learning concepts rather than memorizing. Students must be accustomed to solving the application problems of a material. So, students will be able to solve contextual problems related to the material.
