Abstract

Abstract. The purpose of this study was to analyze and describe students' mathematical connection abilities reviewed through the application of SAVI learning approach based on environment and expository learning. This research is a quasi-experimental research, in this study consists of three stages, namely the preparation stage, the implementation phase and the data analysis phase. This study took two parallel classes which were randomly homogeneous by applying different learning methods, namely the experimental and control classes. Based on the results of data processing obtained Fcount for learning is 119,653 with a significance of 0,000 0,05. Then H0 is rejected or Ha is accepted. This means that there are differences in the increase in mathematical connection skills between experimental class students and control class students. Besides that, it can also be concluded that the increase in students' mathematical connection skills through the application of the SAVI learning approach based on environment is higher than the students whose learning uses expository learning.Keywords: Mathematical Connection, SAVI, Environment Based, Expository.

Abstract

Abstract. This study aimed to improve students' understanding of mathematical concepts by using guided discovery learning based on Toba culture and conventional learning. This research is a quasi experiment research with population of all students of class VII of SMP Negeri 1 Tukka even semester of academic year 2016/2017. The sample of this research is taken by random sampling technique chosen by VIIB class (30 students) as experimental class and class VIIb (34 students) as control class. The instrument used consists of the ability to comprehend the concept of mathematical concepts in the form of description and declared to have fulfilled the validity of the content, and the reliability coefficient. By using different test and descriptive analysis, it was found that the improvement of students' mathematical concept understanding that was taught by guided discovery learning based on Toba culture was higher than conventional learning. Furthermore, it is recommended to the math teacher to use the Toba-based guided discovery learning too as one of the tools to improve students' concept comprehension ability. Keywords.

Abstract

Abstract. Learning is the process of interaction between students and their environment so that there is a change in behavior towards a better direction. So that in generating a positive response it is necessary to improve the learning model. This research was conducted at the fifth grade IT FAZA AZKIA Elementary School, Kelurahan Hutaraja, Kabupaten Tapanuli Selatan, Provinsi Sumatera Utara. Research uses classroom action research. The study aims to determine how students respond to the use of inquiry-based learning models based on the concept of buying and selling on statistical material. This research resulted in the response of students in the first cycle still not achieving a minimum score of 80%. While the response of students in cycle second the entire response of students has reached a minimum value of 80%. So that the response of students has been positive and this has increased from cycle I to cycle II.Keywords: Student Response, Inquiry Learning Model, Buying and Selling Concept
