This brief presents the results of a study on the development of the mobile app-supported math trail program for learning mathematics. This study is a part of the MathCityMap-Project, a project of the MATIS I Team from IDMI Goethe-Universität Frankfurt, Germany, that comprises math trails around the city that are supported by the use of GPS-enabled mobile phone technology. The project offers an activity that is designed to support students in constructing their own mathematical knowledge by solving the prepared mathematical tasks on the math trail and interacting with the environment, including the digital environment.

The brief focuses specifically on the development of a model for a mobile app-supported math trail programme and the implementation of this programme in Indonesia. It offers both an empirical exploration of its implementation as well as critical assessment of students’ motivation in mathematics, their own performance, as well as teachers’ mathematics beliefs. It concludes with a future-forward perspective by recommending strategies for implementation in schools, among the general public of the existing math trails (including its supporting tool). It also discusses strategies for developing and designing new trails and suggests further research in other geographical regions and contexts for continued project development and implementation. Learning Mathematics in a Mobile App-Supported Math Trail Environment articulates an innovative and exciting future for integrating real mathematical tasks and geographic and digital environment into effective mathematics education.

Emertsgrund, BlackCoffeePost. Lebih dari dua ribu tahun yang lalu, Pythagoreans menemukan hubungan antara bentuk getaran string sederhana dan kombinasi suara yang enak bagi telinga dan otak kita. Sejak itu, ahli matematika dan ilmuwan telah belajar banyak tentang bagaimana ukuran, bentuk, dan dinamika nonlinier instrumen menentukan suara khusus mereka. Dr. Bruce Bayly, penyanyi dan pemain biola yang juga matematikawan telah menunjukkan kepada kita tentang matematika di balik musik.

Eschborn, adinegara.com. How does the receiver calculate its position?We will start by assuming that the clocks of the receiver and all of the satellites are perfectly synchronized. The receiver calculates its position through triangulation. The basic principle of triangulation methods is to determine where a person (object) is located by using some knowledge relating the position of the person (object) with respect to reference objects whose positions are known. In the case of the receiver of the GPS, it calculates its distance to the satellites, whose positions are known. (more…)

BlackCoffee Post. Imagine if we don’t have cell phones nowadays to contact other people when we need their help immediately; what would we do? In the past, people had to send letters that would take a long time. Nowadays, technology that has been developing rapidly enables us to send and receive information almost instantly. Daily life must be associated with the use of technology as a tool to facilitate human activity, for example:  people are easy and quick to get information through television, send message to others via mobile phone, and go to other place using modern vehicles. Similarly, the development of information technology also has been very rapid progress since the invention of computers in the 1950’s. This development has several impacts. In this essay I will discuss about advantages of the development of technology in many aspects of humans’ lives. (more…)
