Abstract

This study used the pre-test post-disigned quasi-experimental method. The purpose of this study was to find out the achievement and improvement of mathematical connection ability of students whose learning using the scientific approach and guided inquiry method was better than those using the scientific approach only. This research was conducted at the junior high school level. The instrument used in this study was a test of mathematical connection ability. The results showed that learning using the scientific approach and guided inquiry method was better than those using the scientific approach only in improving students mathematical connection ability, both from the significance of t-test posttest 0.017 and from the results of the t-test n-gain significance of 0.024. For the difficulty of solving the problem of experimental class mathematical connection ability lies in the percentage of questions number 6 which is 46.9% with indicators applying the relationship of mathematics to everyday problems, while the percentage of achievement in the control class is very low in question number 5 is 46.1% with indicators look for the relationship of one procedure to another in equivalent representations. Learning using the scientific approach and guided inquiry method makes creative students associate concepts or mathematical procedures appropriately.

Abstract

This study aims to: 1) know the achievement of problem-solving abilities and mathematical disposition of students, 2) the interaction between the learning model and the level of students' abilities to the achievement of problem-solving abilities and mathematical dispositions and 3) the association of problem ability and mathematical disposition students. This research uses the quantitative approach with the experimental method. The instrument used is a type of description test. Data analysis was done quantitatively by using t-test and two-track ANOVA test. The result of this research concludes that the achievement of problem-solving ability and mathematical disposition of students who gain learning with method Improve is better than students who get conventional learning either reviewed based on the whole students and based on students' early math ability. There is no interaction between learning method factors and the level of students' early mathematical ability toward the achievement of mathematical problem-solving abilities. There is no interaction between the learning method and the students' early mathematical ability towards achieving mathematical disposition abilities. Students have a positive attitude towards the learning of mathematics and Improve Method.

Abstract

In industrial revolution 4.0, education must follow and utilize information and communication technology. Android is an operating system on mobile devices, and Indonesia's most popular and widely used mobile device operating system. The Open-Ended approach is an approach in mathematics learning that provides opportunities for students to explore open problems with various strategies for solving problems. One problem that often arises in learning in schools is the study of the anchovies of each textbook varies, and the material contained in the book does not match the characteristics of the students. To realize this, the world of education needs to implement the use of e-Modules. Seeing this problem, the development of an android-based e-Module with an open-ended approach is required. Research and development with the ADDIE model is this type of research. The subjects of this study were as many as 15 middle school students in grade 8 for limited tests and 30 students for a broader test. The research aimed to produce Android-based electronic teaching materials with an open-ended approach to square and triangular materials. The resulting product is an e-Module in the form of an android package kit (APK). The result of the study concluded that the development of teaching materials with an android-based open-ended approach went well with the practicality test results obtained by 83%, which means that the teaching materials are efficient to use and got 86.6% in the effectiveness test, which means that the teaching materials developed are suitable for use.
