[1] Al Jupri : Supermarket Context in Learning Estimation
Problems
Daily life questions: are there enough?, could this be correct?, and
approximately how much is it?.
Students are learn to solve this kind of problem by estimation
calculation, because most problems in reality are usually appear
in the number which is difficult to deal with exact calculation.

[2] Ariyadi Wijaya : Indonesian Traditional Games in Learning
Measurement of Length
The idea behind applied the
gundu game is to emerge the
concept of indirect
comparison. In this
game, each player should
throw their marbles from
starting point to a pole on the
ground. The winner
determined by compare the
distance of the marbles from
the pole.

[2] Ariyadi Wijaya : Indonesian Traditional Games in Learning
Measurement of Length
All players in each team have to hit a short stick and
then the distance of the fallen stick is measured. The
winner determined by the team which has the longer
distance of the stick.
Students are free to choose measure-
ment tools either the unit which use to
compare the length of distance. The
conjecture for this activity is the students,
while measure the distance of their stick,
may use different tool and unit, such as
their footsteps. It will lead them to
different result since every students have
different size of step.
From this situation, they will
realize that they need to use
same measurement to obtain
same result for same distance.
This basic concept can be used
as the first step in introduce
the standard measurement
for the students.

Learning mathematics outcomes using Android for blind students based on Newma...Journal of Education and Learning (EduLearn)

Blind students exclusively use braille materials for teaching math. Teaching tools that assist blind students' motor and hearing nerves are essential for learning. This study was to describe learning mathematics outcomes for blind students after using teaching material for Android devices based on Newman's theory. This research was a case study of blind students. Blind junior high school students from special schools for visual impairment— extraordinary schools in Bandar Lampung, extraordinary schools in Cimahi, and Madrasah Tsanawiyah with special education in Yogyakarta— contributed to the study's subjects. The study employed questionnaires and test questions as research instruments for both teachers and students. The results of this study demonstrate that learning mathematics outcame blind students' after using teaching material with Android apps based on Newman's theory, specifically: i) reading errors: students can understand the information in the questions; ii) comprehension errors: students do not write down things that are known and asked; and iii) transformation errors: students write down the mathematical model (formula) used; iv) skill errors: students can do calculations correctly; and v) coding errors: students do not write conclusions. The average score of the blind students’ results using braille was higher than that of the Android application.

The winner determined by the team which has the longer distance of the stick. Students are free to choose measurement tools either the unit which use to compare the length of distance. The conjecture for this activity is the students, while measure the distance of their stick, may use different tool and unit, such as their footsteps. It will lead them to different result since every students have different size of step. From this situation, they will realize that they need to use same measurement to obtain same result for same distance. This basic concept can be used as the first step in introduce the standard measurement for the students.
