The role of the teacher is very decisive in efforts to improve the quality of education. To the teacher as an agent learning demanded to hold the learning process as well as possible. The teacher has a very strategic function and role in the development of education, and therefore it is developed as a dignified profession.
Students also tend to use the internet rather than open books. The discussion between friends also began to diminish. The same thing happened in other classes.
Learning is a human activity that will continue until the end of his life since humans were born into the world. Learning brings a change both in actual and potential terms, in this change new skills are acquired, of course, changes occur because of business.
The emergence of learning difficulties not only affects students who have the low ability but also experienced by high-ability students. This can be because, students who are above average (very smart) do not get adequate opportunities to develop according to their capacity, so they feel they cannot develop.
For ordinary people, the internet is only used for social media. But actually, the internet can also be used or utilized in terms of learning. Especially teenagers who often use the internet. Most of them use it only to play social media. In this case, the internet should be used in things that are more useful, such as just learning.
The internet is a computer network that is interconnected using a global standard system. On the internet, there are positive and negative impacts on their use. Tetrutama in terms of learning, where a lot of information can be obtained in this media for information in seeking insight. Most students have used this media to learn. Some just use it to play. With so much information that can be obtained from the internet, this media should be very useful in terms of learning.
Problems that occur in junior high schools, especially class VII, are still many students who feel and experience boredom in learning mathematics. Abstract subjects such as mathematics and loaded with cognitive content, require students to work hard using specific strategies to learn them. These characteristics often make it difficult for students to learn Mathematics. This difficulty can lead to boredom in learning mathematics which can also have an impact on learning outcomes and a decrease in students’ mathematical reasoning abilities, the problem occurs because of a lack of effectiveness in learning.
Based on the description, it can be seen that the reasoning ability is very important for students. If students are able to use their reasoning abilities to the maximum, students can easily understand, abstract, classify, and associate concepts that exist in mathematics. Conversely, if students have not used their reasoning abilities to the fullest, students will have difficulty understanding, abstracting, classifying, and associating concepts that exist in mathematics.
The abilities that must be achieved in mathematics learning are 1) mathematical reasoning ( reasoning and proof), 2) mathematical representation (representation ), 3) mathematical communication (communication), 4) mathematical connections (connections), and 5) problem solving (problem-solving). Of the five standards, there are mathematical reasoning. One of the goals of mathematics learning in schools is so that students are able to use reasoning on patterns and traits, make mathematical manipulations in generalizing, compiling evidence, or explaining mathematical ideas and statements.
