Talking about education, firstly, education is a conscious effort in realizing the learning process in order to make students actively develop their potential to be able to have noble character, intelligence and personality that are good for themselves and society. Along with the development in the world of education that continues to change rapidly or develop rapidly which can change the mindset of educators, from being rigid to modern. That is very influential to education. The main purpose of education is to produce or make someone to have quality, knowledge and character, so that he has a broad view to get the desired ideals and to be able to adapt in environment. Education provides motivation to be a good person in all aspects of life. Education itself is a very important thing in human life. Therefore all citizens have right to get good quality of education. In education the role of a teacher is very important. A teacher is an educator, a teacher and an example for his students. Teaching is a very complicated matter, not as easy as we imagine when teacher is teaching, he must know each character of the students. In addition the teacher must also prepare designs before conducting the teaching and learning process. The teacher must think of ways that are used to increase students’ interest in learning and improve the quality of teaching. With the rapid development of technology, teachers must be able to use these technological developments in the teaching and learning process in the classroom. So that there will be no lag in that development. In the teaching and learning process the teacher only uses the monotonous lecture method that will reduce students’ interest in learning because students may feel bored or think it is not interesting for them. Therefore the teacher is able to apply the technology in learning. It is usually known as Educational Technology. Educational Technology is a medium that is used as a tool in education or the learning process to be more effective, and can be easily observed by students. The purpose of this Educational Technology is as a media to solve problems in learning that can improve learning performance. So that it can increase learning interest for students. Educational technology also help teachers in making media used in the learning process, so that students can attract the desire to learn. By Educational Technology, teachers can create media that enable them to apply the material presented with images on the internet. The material can be presented through videos or stories on YouTube. It is the same as making a TTS column from this technology the teacher can make questions through this TTS. So there is a touch of games in learning. This can increase students’ desire to learn. In addition, this can also make students more active and critical in learning activities.
Abstract---This research problem is caused by the low interest of students in following discrete mathematics lectures. The purpose of this study is to determine the use of learning methods with the provision of rewards in improving student self-efficacy. The population of this study is the second semester students STMIK Royal Kisaran which amounted to 512 people. The sample was obtained by using cluster random sampling method. The sample of research is four classes from 13 existing classes. Implementation of this research by giving rewards and ranking to students who are able to complete the given problem. Technique of collecting data by using test and questionnaire which given to student which become sample. Research data show that by applying this method of learning can improve self efficacy in following lectures on discrete mathematics courses.
The problem of this study is the low student mathematics learning outcomes caused by the lack of critical ability. The purpose of this study is to use the problem posing learning model based on open ended to improve mathematical critical thinking abilities. The population is the second semester of Asahan University students, amounting to 110 people. The sample is obtained using the cluster random sampling method. The study sample was two classes from 3 classes. The implementation of this research by giving use the problem posing learning model based on open ended. Data collection techniques by giving tests to students who are sampled. The research data shows that by applying the use of the problem posing learning model based on open ended to improve athematic critical thinking abilities in participating in probability courses.
This study aims to predict the smoothness of installment payments in cooperatives, making it easier for staff to analyze credit lending. Lack of prudence in analyzing credit results in customers who are in arrears in paying installments, resulting in bad credit. To minimize errors that exist, it is necessary to evaluate the provision of loans to prospective debtors. By utilizing past member criteria data in the past that will be used to predict smooth payments using data mining. The data mining technique used is the Naive Bayes classifier method. The prediction process uses the naive Bayes method, namely by determining the probability or opportunity based on the previous member's data, and the results are used to help make a decision. The criteria used are member data: employment, income, house status, number of credits, and type of credit. Based on the naive Bayes method, the results obtained are 90.00% accuracy, 0.880% AUC, 83,33% recall, and 100% precision.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
